Might want to have a look on the xs forums, they've had quite a few A64's cooked due to overclocking. It *seems* to be the memory controller on the cpu that fails, sometimes with and sometimes without added vdimm or chipset voltage. Careful.
Yeah, I worked that out about 3 seconds afterwords, the hard part was working out the URL. Seems they seem to have destroyed all their chips by trying to push obscene voltages through them beyond what these will let you do normally, so I don't think this is a problem.
Well, regarding the "Screwed Graphics at 233+" well, here I am at 234 curtesy of Mr Voodoo 3. So yeah, unbelieveably, my entire system overclocking is being held up because of my Radeon 9700. Way to go ATi :shakehead
The board seems fine at 240MHz FSB too, but I don't want to keep it that high as the voltage I have to use causes the processor to be obscenely hot as this stock cooling doesn't seem to be able to cope. A decent compromise seems to be 235Mhz as that only needs about 1.72v, still, I don't know why I am bothering as the damn Radeon won't go past 228. ATi need to look back at some of the older technology I think (and it's going to be a long time until I get a new GFX card. On the other hand, I could just use my Voodoo 3 until I actually want to game again as I don't play games often...)
We have upgraded your order to a priority service and you should receive it by Tuesday at the latest. You are able to track delivery of your order via the orders section.
So you are using the VooDoo3??! Well if you aren't gaming, it doesn't matter about the 9700 pro. That's a nice overclock, I haven't even started overclocking mine yet.. Im just glad it's stable...
Mine locked up about 15mins ago, but I thought "lets leave it for a minute" and about 20 seconds later it unfroze..... It may have been a fluke, but i'll wait next time too, see what happens.
With eBuyer, I just sent them a ticket stating that I "urgently need the shipping upgraded"..... so they did (Didn't know if it would work or not).
Mine is getting wierder though... it hasn't locked up since last night. All that happens is I get one of my two hard drives... just takes an age to access.. which freezes up the machine for a few seconds... Im starting to wonder if its the drive.. and not the rig...
This might be a stupid question but based on the alarming amount of problems you guys have had. Is that board stable at stock speeds or is it always unstable. I haven't been able to figure that out yet.

Im gonna nudge ebuyer .. worth a try..
But that is what is happening to mine, it goes to access the drive.... and everything just freezes....... and then a few seconds later, unfreezes and the drive actually does what it was supposed to do...
Though at one point when it froze, a few seconds later Windows blue-screened with "MACHINE_CHECK_EXCEPTION"...
EyesOnly: Mine is unstable at stock and overclocked, so I am keeping it overclocked (no point having it go stock and crashing when I can have it go faster and crashing )

SYMPTOMS
Your computer may generate the following Stop error message on a blue screen:
STOP: 0x0000009C (0x00000004, 0x00000000, 0xb2000000, 0x00020151)
"MACHINE_CHECK_EXCEPTION"
Note that the four parameters that are inside the parentheses may vary.
CAUSE
This behavior occurs because your computer processor detected an unrecoverable hardware error and reported it to Windows XP. To do so, it used the Machine Check Exception (MCE) feature of Pentium processors or the Machine Check Architecture (MCA) feature of some Pentium Pro processors. The error may be a result of any of the following:
* System bus errors.
* Memory errors that may include parity or Error Correction Code (ECC) problems.
* Cache errors in the processor or hardware.
* Translation Lookaside Buffers (TLB) errors in the processor.
* Other CPU-vendor specific detected hardware problems.
* Vendor-specific detected hardware problems.
STATUS
This behavior is by design.
MORE INFORMATION
A machine check exception occurs when Windows XP and your hardware platform cannot recover from some type of hardware error so that the system can continue to run successfully and reliably. More specific diagnosis of machine check exceptions is difficult and there is no general solution. Contact your hardware manufacturer or a computer hardware technician for help with troubleshooting this issue.
Machine check exceptions are frequently caused by one of the following conditions:
* Running the processor or mainboard beyond its specifications. For example, overclocking the processor or bus. Microsoft recommends that you run your hardware at the manufacturer-rated speeds.
* Noisy power, overstressed power strips, outmatched power supplies and failing power supplies can destabilize your computer. Make sure that you have a stable, reliable power supply to your computer.
* Extreme thermal conditions caused by the failure of cooling devices such as fans. Make sure your cooling devices are all working. * Damaged memory, or memory that is not the correct type for your computer. If you recently changed the memory configuration, revert to the previous configuration to determine what is wrong. Make sure that you are using the correct memory for your computer.
NOTE: Your hardware may support additional error logging features that capture the machine check exception and suggest a more specific solution.
The Pentium and Pentium Pro processors provide a mechanism to detect and to report hardware-related problems such as memory parity errors and cache errors. To signal a hardware error, the processor signals the detection of a machine check error by generating a machine check exception (Interrupt 18). Windows XP reports that the error occurred and displays parameters that you can use to decode the exception. Contact your hardware vendor or processor manufacturer for information about the Machine Check Architecture or see the Intel Pentium Pro Family Developer's Manual - Volume 3: Operating System Writer's Manual.
Hmm.... completely different. Makes me think it isn't the RAM
I am getting stupidly high temps with this damn processor. I have just redone the AS and reseated it, but it is still really high. What is yours at?
EDIT: 2365Mhz @ 1.75v = 45'c idle, 73'c Load.
The AS is on, it has perfect contact, the processor isn't giving any errors and the heatsink is only warm (copper on the bottom is hot, stupidly hot though). Which makes me think the Diodes temperature reading may be wrong...
The diode could well be wrong.. Im at 41c.. heatsink is only warm. Hammer processors do run cold. I benched an opteron system for 4 hours straight.. and the sink was only lukewarm.
39'c in the BIOS
31'c in Windows (still dropping, must be the HLT instruction)
45'c under load (with SSE(2) running)
The processor can heat up so fast, I mean before, it could heat up 10'c in 1 second or less (went from 44'c to 55'c in the 1 second interval). So, I have a feeling our temps are going to be higher than everyone elses as it seems that the thermal diode is infact in the center of the processor, so unless we cool the entire thing down with liquid nitrogen, it is always going to report high.
So basically, rule of thumb will be that it's only too hot when it starts failing
Not sure whether its the power supplies or the motherboards fault, but the RAM is fluctuating 0.03, the HT is 0.03 over voltage and the processor is 0.05 higher than what it should be. Kind of makes everything confusing.
Could it be the board itself that's broken and not the ram. In 2-3 days when you'll both have your new ram we'll hopefully find out. It's hard to believe that this thread is now up to 7 pages and most of it has been about bad things. Since i'm considering going 64bit i've given this thread a lot of attention as perhaps many others who wants to go that way also has.
If this continious then it's defently best to wait until more boards have been relised before switching.
The common part here is the TwinMOS memory. Yes, we have two different part numbers.. but they are on the same PCB.. this would lead me to find a more likely fault with the ram rather than board. The hammer family have the onboard memory controller as you know, so it's fussy about what memory it uses
Truth, I dont think either Enverex or myself would put anyone off going Athlon 64. It's a tremendously powerful platform, yes it has a few bugs.. but overall.. considering it's infancy, it's awesome.
I am back at 228Mhz now so I can put my Radeon back in (the voltages needed for the processor above 230 were too high for the crappy stock cooling, especially as it doesn't seem to make good contact with the CPU). And it all seems fine at the moment. Someone recommended putting the HT link down to 600Mhz, but last time I did that an alarm went off and the machine wouldn't turn back on
Enverex... I was wondering whether we should change/edit the title of this thread... and sticky.. as a sorta pseudo "Athlon 64 discussion" thread. 8 pages and counting
I think the title "Enverex and Shorty's discussion where Enverex talks to himself...... alot...." suits better
Agree.
I know you 2 have different boards that what worried me. One of you might have gotten a bad board but not 2 and from different brands. AS for sticking this thread that might be a good idea. Yuu seenm to be the first ones to go 64bit other then citrix so newbies would prolly want to know what you now know. For instance which brand of ram to choose or not.
I want to lie, shipwrecked in comotose, drinking fresh, mango juice. Gold-fish sholes, nibling at my toes, fuuun fuuun fuuuun, in the suuun suuuun suuun.........
Its cold outside, There's no kind of atmosphere, I'm all alone, More or less. Let me fly, Far away from here, Fun, fun, fun, In the sun, sun, sun.
Well, the RAM........ is ****. It won't even do 228 at laxest timings...... or even 220...... so consequently it is stuck at 190 (DDR333 with 228FSB) at max timings. Sandra still gives less than 3000 .
No lock-ups (other than RAM related (i.e. no HD light on)) yet, but i'll let you know if it happens.

Im gonna nudge ebuyer .. worth a try..
Drive, maybe, if it has a high seek and a small integral I\O buffer(ever seen a saturated hard drive buffer??), especially if IDE actual rates are running fast or the bridge is hot also(could be bridge, separate IDE controller, saturated HD buffer).... Since PCI and AGP fixation can stabilize IDE sometimes(how well this will work depends on bridging bus pipe and subbus off that bridge timing strategy ) you might try that. Ditto for video issue.

Im damn surprised by that. VERY surprised by that. What dimm voltage?

At default voltage and speed:

31'c in Windows (still dropping, must be the HLT instruction)
45'c under load (with SSE(2) running)

Enverex has the ABIT and I have the MSI

Edit
You beat me to it shorty. Oh well.
It arrived in a box big enough to fit 4 motherboard boxes. I mean, wtf were eBuyer thinking? lol.
About to fit it....
Bloody hell Ebuyer.. someone must have put a rocket up their arse!
Let us know! Mine didn't appear
