MSI K8T Master2 FAR notes

drasnordrasnor Hawthorne, CA Icrontian
edited Feb 2010 in PC Building
Well, since we have our own forum now *gasp!*, I figured I'd post my impressions on my choice of motherboard in my dual 64-bit system.

By and large the K8T Master2 is the cheapest board for dual Socket 940. However, there are a few things you need to be aware of if you're considering purchasing one of these.

1) The cooling situation on this board is downright bizarre. It does not take standard Opteron heatsinks. The board has a motherboard socket hole pattern matching that of the Intel Socket603/604 Xeon and Socket423 Pentium IV. However, at least one processor socket will have a plastic HSRM that accepts Socket478 Pentium IV heatsinks. I say at least one because some people have these on both sockets, though mine only had one on the top CPU socket.

MSI bundles heatsinks with the board, but they are loud unless you use the SmartFan control feature in the BIOS. This feature cuts the voltage to the CPU fans until the CPU temperature rises above a minimum threshold temperature that you set (60 C and up in increments of 10 C) at which point it brings the fans up to full speed. I found these heatsinks to be inadequate for use on two Opteron 248's in my Lian Li PC-7 midtower.

I use a pair of Swiftech MCX478+ heatsinks with a modified retention brackets (the $3 extra ones) coupled to high-output 80mm Panaflo fans. I modified the retention brackets by cutting off the holes that allow mounting on Socket478 systems, leaving only the Socket423/603 holes and allowing me to use 80mm fans. Alternatively you can buy the motherboard retention kit for a MCX603 direct from Swiftech; it bolts onto the MCX478+ without any modification required since the MCX603 and MCX478+ are essentially the same heatsink.

Behind each CPU socket on the back of the board is a massive steel load plate attached to the board with insulating foam. The load plate has threaded inserts that come into the holes surrounding the CPU sockets. The threads used are metric 3mm threads. If the heatsink you're planning to use has English threads on it, you will need to either replace the offending bolts or standoffs with 3mm metric ones or cut 3mm metric threads onto the bolt/standoff. I chose to cut 3mm threads onto my Swiftech standoffs using a thread die you can get at a decent hardware store.

MSI's explanation for the odd hole spacing is so that you can easily watercool it by not having to wait for Opteron and Athlon64 water blocks to become available, but rather use existing Xeon blocks.

2) There is about 2mm of clearance between the AGP Pro slot and the lower CPU heatsink. Don't even think about installing a Zalman heatpipe cooler; it won't fit. The stock MSI cooler for the lower heatsink is offset from the center of the CPU socket to allow extra room for your AGP card at the cost of decent cooling. Depending on the memory heatspreader configuration on your graphics card, you may not have room for an after-market cooler. Mine doesn't have memory heatspreaders, and I live with having only 2mm clearance between my Panaflo and the AGP card. The card hasn't complained yet.

3) Many people have had trouble using Corsair registered ECC DDR400 with their K8T Master2 systems. Their machines exhibit stability problems and occasional pagefaults. I had these problems initially, but they went away when I bumped the DDR voltage up to 2.65V. My machine has successfully complete 7 passes of Memtest86+.

4) Don't use Memtest86 3.0. It cannot properly detect AMD64 CPUs and chipsets. Use Memtest86+ instead.

5) The two IDE connectors, floppy disk connector, and both SATA headers are in the bottom front corner of the board. Make sure cables meant to reach drives in the top of your case are the same length as your case's height. Really.

6) The K8T Master2 does not support dual floppy drives. :(

7) Since this board is a standard ATX board (12"x10") and not an E-ATX board (12"x13"), it will fit in most standard ATX mid-towers and desktops. Just make sure you have adequate ventilation to dissipate two fast, modern processors worth of heat.

8) Due to space limitations and less confusion-related problems with people running a single Opteron or AthlonFX on this board, there are only two banks of RAM (4 slots). They're both controlled by the top CPU, so you there aren't dual memory interfaces on this board. In other words, if the second CPU has to do something in RAM, it has to go through the HyperTransport link to the first CPU and use the first CPU's memory controller for memory access. This isn't any slower than the CPU having to go through the Northbridge for memory access like in a normal 32-bit system so you aren't likely to notice unless you're benching versus someone using a 4-way Opteron system.

All that being said, this is an excellent performer and I'm satisfied with my purchase. It's about half the price of the next board up, and is the only dual processor board that I'm aware of that uses the VIA K8T800 chipset instead of the AMD 8000-series logic. The AGP performance on the K8T800 is supposed to be better, but I haven't really looked into it.

    Outstanding. I multitask while I game, so I can frag away happily in Counterstrike at maximum detail and 1600x1200 resolution while listening to Winamp and running Outlook and Trillian in the background.

    I'm real unhappy at the moment though because ATI just sent me another lemon All in Wonder 9700 Pro, even after telling me that they would test it this time. The AiW still has the same problem of horizontal light and dark patterns. I've decided that they're testing these cards with DVI displays, and as such don't get to see when the DACs are failing and see the results on an analog display such as mine. I've already ruled out dirty power (installed a phat capacitive filter circuit on the AiW's power dongle), EMI (the GeForce 3 Ti500 doesn't give me this problem), bad monitor (switched monitors), bad cable (switched cables), bad DVI->VGA adapter (switched adapters). That pretty much leaves bad card and bad drivers, neither of which are things I can fix.

    The MSI 1.1 BIOS makes the TV Tuner work (it doesn't in the 1.0 BIOS), but it also makes my machine unstable. So frustrating... MSI tech support is nonexistant no matter what anyone else says: they don't respond to e-mails. They do respond to RMA forms however, but I'm not ready for that yet. The 1.0 BIOS works, just not with the All in Wonder.

    EDIT: I think I may have fixed the instability in the 1.1 BIOS. I purged the PCI IRQ/DMA configuration tables in the BIOS and it seems to have fixed the problem.

    Another note:
    I experienced profound stuttering with my Audigy 2 Platinum and the 1.1 MSI BIOS. This problem did not occur using the 1.0 MSI BIOS. I fixed the problem by applying the following patches from http://www.georgebreese.com/net/software :
    Patch for Creative Labs SoundBlaster Live! and Audigy-series drivers
    "PCI Latency" patch for VIA chipsets

    I don't think they'd fit, and even if they did, there's no way to mount them without some serious modification. A heatsink for this board can have a maximum footprint of 80mm square, +/- 1mm. They're that close.

    They will, sort of. If you're lucky, your board will come with s423 to s478 HSRM's on both sockets. Mine only had them on the top socket. You can use any P4 heatsink that will mount to a s478 HSRM as long as it doesn't exceed the 80mm square footprint.

    Does this board have any multiplier adjustments ?
    What is max vcore and vdimm?

    Thanks :)
  • drasnordrasnor Hawthorne, CA Icrontian
    edited May 2004
    Opterons have a fixed multiplier so there aren't any multiplier adjustments and no way that I'm aware of to unlock the multiplier. I wouldn't want to overclock this board, since the HT bus and PCI/AGP buses are coupled (raising HT frequency raises AGP and PCI clocks and disables SATA RAID). If you're going to build an overclocking FX rig, you'll want to consider one with a single CPU socket (s939) and a K8T800 Pro or nForce3 Pro 250 chipset because they have AGP/PCI locks, PCI express, and compatibility with newer AMD 64-bit processors.

    Max Vdimm is 2.65V.
    Vcore is not adjustable AFAIK.

    Butl I have an FX51 and it's unlocked, and from what I've read at MSI's site this board will run a single Opteron or FX.

    I have an MSI K8T Neo FIS2R for my soc 754 3400+ and allthough it dosnt have much in the way of voltage adjustments it a sweet overclocker. 228 FSB is a very stable and easy mark.

    This board has came way down in price localy, and is very tempting. I would realy like an MSI board for my FX
  • drasnordrasnor Hawthorne, CA Icrontian
    edited May 2004
    If you already have an FX-51, you'll have to go for a single 940 board then. I'd wait til the nForce3 Pro 250 and K8T800 Pro boards start hitting the streets and see if they make a single s940 board with those chipsets. If not, Tyan has some out and if you really want to you can use this board. Be aware though that you can only use low-profile cooling on the Northbridge since a large heatsink will interfere with the AGP slot.

    Hey All,

    I'm a noob to this thread but I've been scouting around the web for a solution to a problem I'm having that I think may be DDR related.

    MSI K8T Master2-FAR
    2 x Opteron 248
    2 Gig of Corsair TwinX1024RE-3200LLPT
    2 80GB WD800JB (Raid Striping Array using builtin VIA Raid on mobo)
    1 80GB WD800JB (compressed)
    WinXP SP1 and critical updates

    When I try and compress a large amount of data using either Winzip 8.1 (full installation) or 9.0 (evaluation) I get crc corruption errors when I unzip. I've experienced this trying to back up large outlook archives and other things. I was thinking this might be a DDR issue but I cannot run memtest86 3.0 successfully (just noticed that I need memtest86+ from above post so I need to test this).

    Any other ideas as to what might be causing this?

    Could this be a mobo issue?

    I'm hoping it's just something with WinXP and not a hardware issue - when I get around to reinstalling I guess I'll find out.

    Thanks!

    I had that problem initially too so you're not alone. It went away when I dialed up the RAM voltage in the BIOS to 2.65V. Try doing that and then running the latest version of memtest for a few passes to make sure everything's happy.

    Thanks so much for the quick response - I will give this a shot

    What are the operating temps of your CPUs? I'm concerned b/c my BIOS has CPU2 running hotter than CPU1 - although it seems like it should be the other way around unless CPU2 is primary for some reason?

    BTW I'm using the heat sinks that came with my k8t master2 - I did use artic silver 5 on the sinks (removed the heat pads from the sinks before I did this) when I installed them, but other than this I am pretty much running a stock system.

    i believe cpu2 has a smaller heatsink (slightly) and is also situated in a hotter part of your case (as far as airflow is concerned). look at this thread:

    If by "slightly" you mean a lot smaller + off-center and if by "in a hotter part of your case" you mean strapped to the back of your GPU then you'd be correct. My temps are fairly equal because they've got the same heatsink and fan on both processors and I have decent airflow.

    On a side note, I flipped the fans on the processor heatsinks over so this is a change from the configuration in the Cooling thread. I figured I'd experiment since other pin grid heatsinks like the Alpha PAL's ship with their fans sucking air out of the heatsink rather than blowing in.

    Hey All,

    I've upped my DDR voltage to 2.65 and was running memtest86+ but I cannot seem to get past 50% of test 2 w/out having it freeze up.

    I had this same issue with memtest86 v3.1 (I know this is test is not suitable for opterons)...

    any ideas?

    I am going to run my "winzip" test and see if it results in the same crc errors as before, hopefully at least these will be resolved.

    Could there be some issue w/ the mobo (already RMA'd once) that is causing this? Is there any DDR issue that could cause memtest+ to freeze up completely?

    I believe I am using BIOS v1.1 - I need to restart and check - could I need some kind of BIOS update?

    Thanks again for all the help!

    Well, you're not going to like my answer...

    Standard diagnostic procedure says test each individual component of the machine in a known-good test machine to try and isolate the damaged component. I don't put any faith in those utilities for telling me exactly what the problem is. For instance, earlier today I got lots of kernel page errors that many would automatically assume RAM, except that I know my RAID array made some funny noises before I could slap the VIA latency patch on (filesystem corruption).

    That could be your problem, but I doubt it since I only had that problem after loading the VIA Hyperion drivers and I didn't have it in DOS or Linux. I had real trouble with the 1.1 BIOS and system stability in Windows before applying the latency patch, but everything is happy now. Someone earlier was badmouthing that fix as being ancient, but it was designed for the 6235/8237 Southbridge and that's what's on your board.

    Your best bet is reposting your problem in Hardware Discussion with a title like "Can't pass Memtest, what's the problem?" and get some better help than just me.

    one quick question...

    by the "latency patch" do you mean the beta v1.35 Award BIOS? When I go to the MSI site I only see the v1.1 BIOS and the v1.35 beta for the k8t master2.

    I've avoided mucking with the BIOS thus far b/c I know that I will put my workstation down if I screw it up. But if this could potentially be the issue then I might as well suck it up and take the plunge.

    I will post this in the hardware forum as well and see if I get any bites.

    thanks again drasnor!

    okay - reading your post closely this time I see the patch was for VIA and not for the BIOS. Sorry. Been a long day. I will look into this and see if it yields anything.

    Would this affect memtest86+ though?

    Is there any reason why test2/50% would stall for an unusually long time - could I just not be waiting long enough for it to complete?

    headed to the hardware forums as we "speak"...:)

    The latency patch in question can be found here. It shouldn't affect memtest86+, which is why I don't think that's your problem ;)

    No, IIRC Test 2 doesn't take very long though the later ones do.

    Drasnor,

    I just purchased the MSI K8T Master2 about 4 days ago. I am using it with two Opteron 250.

    I am having all the problems with noise everybody is complaining about..... Since the begining of your research on this matter there has been a lot of elapsed time. Are you aware of any new solution they may have invented and sold commercially.

    Do you know what is the recommended temperatures. What are the acceptable temperatures. With the fans in high I get 47 and 46 centigrade. With the fans on low I get 57 and 56. I read somewhere that with the pipes people should be getting 37 and 36 centigrade..... is this correct?

    Good question. I really haven't looked around for new heatsinks that fit lest I spend more money on the project ;) so I'm not aware of any new ones though there probably are several that will work.

    Acceptable temperature is a matter of opinion. The processors are rated for 80C, but they typically show instability well before that. The only way to find out is to run lots of CPU intensive stuff at those high temperatures and see whether or not it crashes. I won't accept anything higher than 50C.

    Remember to look at the deltaT when looking at people's temperatures. Sure, 36C is an outstanding temperature if your case temperature is around 30 C (typical for a good case in a normal room) but it kinda sucks if the ambient is much lower (if your case is near freezing, deltaT would be around 36C in this case). My deltaT is around 20C, which isn't particularly great but is about 10C better than what MSI could do for me.

    I suspect that the K8T Master2 reads temperatures high, but I can't verify without a temperature probe. Touching the sinks with my bare hand is accurate to within 5C, and it feels a lot cooler than 48C.

    Bottom line: experiment and see what works. I think it'd be awesome if someone else came up with a different solution than mine and we could compare the results.

    Hi,
    I have recently purchased a Master2-Far with 2 opteron 248. The board came with no heatsink/fans. I have read the thread about 'Cooling the Master2'. However, i don't know much about hardware so i would prefer not to have to do any modif.

    Also, the difference with what i have read so far is that my board came with identical brackets for both cpus. I have a picture here :
    http://www.sebastienm.com/master2far.jpg

    1 - Sorry about this trivial question, but i have no idea whether they are Xeon/P4/Opteron brackets... or which socket number they correspond to. Anybody? (from the picture above)

    2 - I called MSI.
    ... by the way, i first had a hell of a time to get in touch with them... it took them 10 days to reply my first RMA by email, but then i called them by phone and i left my number on the voice mail, and they called me back within the same day. They said they could not recommend anything besides the usually shipped system, but they added that some customers would switch to p4 (or did he say Xeon?) heatsink/fan... and he mailed me an additional bracket (since i supppose the ones shipped with the board are usually 2 different types). These brakets are in fact the same as the ones i already have on the board (see pix above)

    3 - From 1 & 2... my priority being on noise reduction (a good cooling is enough; not need of 'excellent'), any idea of heatsink/fan?

    4 - My CPUs are OSA248CEP5AU. Have you heard of any issues i should be aware of with this stepping (CG) and the Master2, before i plug it in?

    5 and final - The board doc says it takes only DDR333 with dual cpus, but i have heard people speaking of DDR400 earlier. So, does/doesn't it work with dual processors?

    Thank you and once again sorry if my questions sounds stupid.

    Some of these have been answered already but since the answers are buried within threads I'll go ahead and answer them again. The questions are valid, though just remember that in general asking stupid questions and sounding stupid is preferable to how you'll look if you shell out serious cash on hardware you can't use or return. Getting these questions out of the way now will save you a lot of grief in the future, so feel free to ask away though we do ask that you do a minimal amount of Google research in advance ;).

    I was less than impressed with their knowledge of their own hardware as well during my own contact with them. You'd think they'd have better answers for anyone wanting to purchase a workstation board. They designed it after all.

    The brackets on your motherboard are compatible with any heatsink using the standard s478 (Pentium 4) heatsink mount. The holes on your motherboard that the brackets are screwed in through are the same as that of s423/603/604 (very early Pentium 4 and all Xeon). What this means is that you can use just about any standard Pentium 4 cooler that will fit and any Xeon cooler designed to mount through the board (with screws instead of clips).

    The main caveats when buying heatsinks for this board is that you need to make sure the heatsink stays within an 80mm square footprint (anything with more than an 80mm fan is unusable) and that the thermal contact patch on the underside of the heatsink is large enough to cover your CPU (shouldn't be a problem). If you want me to toss out some names for you, I was considering going with Vantec Aeroflow2's but I didn't have the second set of brackets to make it work. It's Vantec's take on the very successful series of heatsinks by Dr. Thermal/Thermal Integration. These will probably also work. So will these.

    5 and final - The board doc says it takes only DDR333 with dual cpus, but i have heard people speaking of DDR400 earlier. So, does/doesn't it work with dual processors?
    I'm not up on my Opteron steppings so I really can't answer number 4. As for number 5, the memory speed in all Athlon64/AthlonFX/Opteron systems is determined by what kind of memory controller is on the processor die. This means that the board has essentially nothing to do with the kind of memory it takes, which is completely opposite of how every other computer before has worked. At the time MSI released the board, all Opterons only took DDR333. That changed a little more than a month later with the release of the Opteron 248, and AMD went back and quietly validated all the currently released 246's and up as DR400 compatible (I remember hearing somewhere that it was because they were waiting for DDR400 to become an official JEDEC standard). I read recently that all new Opterons 240 and up are DDR400 compatible, but I don't know what core steppings that corresponds to. You have 248's so you should be fine (I got my 248's literally when they came out and am using 2GB of DDR400 with them).

    Thanks a lot, Drasnor. Your reply clarified a lot of things for me.
    Google is good and necessary in order to find info (that's the way i found Shrot-Media.com) but too many times, while it answers my question, it opens the door to 10 new questions :-)

    For now, I am gonna try 2 of the Thermaltakes you have listed (TR2-M12 SE) as they are only 21 db. I'll move to something else later if they don't cool enough. However, I'll first try to lower the temp in the chassis. With my current system, the inside of the chassis feels cool (i have no probe though; maybe i should check with a regular thermometer). I may get one or two additional fans too.

    Concerning the memory. i have already bought 2x1Gb DDR333; i guess i'll sell them back and get some DDR400... but now i am tempted to get 2x2Gb ;-)

    So far i got the MSI board + 2 Opteron 248 + 2 x 1Gb of DDR333 ECC Reg for $1200... but i still need to make sure all the parts work properly :-)
    I'll use most parts from my current system (if compatible, which i am not completely sure yet). If everything works fine with no surprise (moneywise) I'd like Sata Raid with two Raptor 10k rpm drives. Currently i have 1 x 80gb and 2x 200Gb.

    ... almost there...

    Thanks again,
    Sebastien

    Need help with K8T Master2-FAR (x2). I can't get any ram to load on either of my boards. I figure it has something to do with ECC, registered type ram which I know very little about. I built plenty of computers, I bought these boards to replace my dual athlon mp 2400 (both fried because of bad bracket). It's a 900watt system, 600watt for the board only, 300watt for fans, amp, etc. Water cooled. Nvidia pci 5000 i think and a Nvidia 7300 gt AGP (both BFG). Lots of different ram, none work.

    Is any of the ram ECC? I believe this board needs ECC.

    Confirmed on that. I had almost the exact same setup as Dras in my old system with 2GB of DDR-400 ECC Registered.

    Ok well I ordered a gb of registered ECC for 40$ to test it out. Ill order more when it works. It supposed to be built for this board though. I'll post some pics but they don't do there justice, it got really messy when I was trying to get it to work.

    Mo pics, almost everything is home made. the water blocks were made at my dads work and there really nice but those ugly brackets i got on them aren't. those black things hanging out of the front is temp gauges just not mounted yet.

    Got the ram, worked for a little bit then rebooted from increase of 200mhz to 233mhz, now computer won't boot... again... water cooling read 31c and 34c and pc read 32c n 34c so it didn't overheat plus I put the overheat protection on. tried emtpying the cmos by removing battery twice, other then that no idea why it is not working this time.

    DDR-400 runs at 200MHz and this board isn't much of an overclocker. Also, your case mods and custom water cooling make this the most awesome thread necro ever. Welcome to Icrontic!

    Remove all but 1 stick of ram, see if any 1 stick is causing the issue. 200 to 233 is a pretty sizable overclock for ECC Ram, you might get away with 10MHz, but not much more.

    Yeah, I could never touch the RAM speeds on that board, and the FSB overall was pretty touchy. It's basically a server board in ATX, rather than E-ATX format.

    Also m_wally: I have a ton of stuff leftover from that old build. I have RAM (which may be suspect) (4x512 DDR-400 ECC) and 2 Opteron 246 processors if you're looking for any spares.

    Oooo more ram. How much? as for opterons I was close to frying them today but there still kicking.. water read 57c after the peltier could only imagian how hot it was running. But ya its working now, when erasing the cmos you have to jump the pins too:bigggrin:. Need to add some rads to this. Had to move it so I had to drink the 60c+water with red dye. Not fun
