Does the nf7-s v2.0 detect ddr400 automatically?

That is, do i have to just slap both ram's in and forget about it, or must i do something in the BIOS or something? (If so, where in the bios would that be)?

I know it defaults at 100 for the cpu fsb... so i have to change that to 166, but how bout for my ram?

thanks

    It will auto detect but you really want to run syncronus fsb and dimm speeds. That is you want the ram to run the same speed as the fsb. Just go into softmenuIII setup and select 3/3, 4/4,5/5 or 6/6 for the ratio.

    well my barton 2800 is 333 fsb... 166 in bios, but my ddr can do 400 ... I assume 200 in bios..

    I was thinking where in the bios is the clock rate for the ram... so i can make sure it was 200. I mean, the mobo supports ddr 400 ram, so why put the fsb lower --- that is, why would it be beneficial to run the same speed as the fsb?

    AND, is there a difference btwn 3/3, 4/4, 5/5, and 6/6?
    (According to what i think it stands for... i dont see a difference because it is simple math.. but why would they be there if they are the same?)

    And what is the default "by SPD" mean... the manual dont say :)

    The RAM cannot run at a base faster than the CPU or the CPU will barf. Period-- it will throw its little electronics hands and say "I can't cache what you are sending me this fast, STOP it." This is always so.

    So, you can run the ram slower, to match CPU, or you can get a faster base CPU.

    You can, and this is where the confusing part comes in, run RAM at slower base than CPU. The CPU will pause and wait if it knows how often and long to wait.

    By SPD lets the BIOS talk at teh RAM ship and have the RAM chip tell it how fast it can run-- literally, done with electronics but they do send query, reply, and then BIOS figures out how fast it CAN run it.

    When you manually setup RAM you override BIOS auto settings. The other numbers other than 3/3 apply only if other busses get set certain ways in relation to the RAM and CPU bus-- ignore unless broken for those.

    Normally if By SPD works, let it be. If broken,then plan on lots of playing as if you mess up RAM settings manually very badly the system will not boot right until the BIOS's CMOS work table is cleared.

    Thanks for the help guys...

    and in order to get this straight... if i dont touch anything in the bios (that is, before i overclock or whatnot) then my pc3200 ram will run at pc2700 speeds?

    if that is true, then i understood what you said ageek, if not, im a dumass...

    That's right PC2700 = 333MHz (AUTO mode) to match your CPU.
    If you select SPD is gonna boot @400MHz so you need to raise FSB to 200MHz to compensate.

    For knowledge purposes... if you leave your fsb of your cpu at 166 and leave by spd for the ram...

    what would go wrong or what would happen if you didnt compensate?

    thanks guys!

    Ummm.. but you can run asynchronously... that is why they give choices such as 3/6 ....

    That is the whole reason I am confused...

    Read this, especially the conclusion

    Um, err.... Um, err.... Only if you want to use SLOWER RAM than FSB. OR overclock FSB to meet RAM and deal with a sudden overheat problem that increases a lot. To increase FSB over 15%(to 166 + 24 or 190) gives you issues with heat adn speed rattioing that most people handle with huge heatsinsk and massive airflow or water cooling-- and a good water cooling rig is more expensive than a better CPU these days.

    You can try, I do not expect it to be stable. CPU is likely to die.

    Then why would they give a ratio choice of 3/6... which would make your ram bus speed twice as fast as your fsb...:confused:

    thanks for pointing that out though, could have led to bad things!

    if i put my fsb at 166, which it should default at if it wasnt for the mobo, and left it "by spd" which you earlier recommended... would everything be fine...? I assume it should, as i didnt change the ram speed at all...

    Try it. Will not boot if the BIOS cannot get a good setting. THAT part depends on BIOS.

    From your link:
    The bottom line here is using an Asynchronous bus doesn't give you a real boost in memory bandwidth. Using a true 166Mhz FSB is what you want from your motherboard.

    Ageek, it will boot just fine.
    Look Torque, you have a mobo/CPU/RAM combo that can handle 200MHz FSB easily without raising the voltages so why run it slower?
    Noting bad can happen and as long as you don't raise voltages, your CPU will run cool without the need for any extra colling.
    I run my 1.7GHz @2.2GHz (200x11) with default voltages and tight mem timings. I don't have WC'ing nor massive airflow, temps around 33c idle/42c load on a hot day like today (100+)

    If you want super stability without any fun, run CPU/RAM at AUTO (166/166) and be done with it.
    You might be able to use tighter memory timings as well since your RAM will be under-specs.

    Ok, try whatever you want.

    I build systems for stability. I like them to run months at a time-- they DO run weeks at a time between reboots and get sold to second users and stay stable. From now on any thread that gets into OC beyond about 15% I will not stay in. Simple. Too much milage variance from person to person depending on stability of PSU, heat and environment details, and other things like how clean and stable incoming power is and understanding of exactly what to do or not do.

    Well..., that's your choice but you might not get to post ever again then.
    You see..., around here most people overclock their systems... :D

    John,

    Look at my sig and you will see that I'm O/C'd more than EQuito on basicly the same chip he is using. I have been running this config for almost 3 1/2 months without a single problem. The "B" core Athlons are actually made to run 166 instead of the old 133. that makes running @200fsb not as bad as one may think.

    Thank you so much for the help... I really appreciate it, and im sorry if i caused any trouble...

    I still have two questions... hopefully simple... then i'll dissppear lickity split.

    1. If i do overclock (most likely) i know how to change the fsb to 200, but should i leave the ratio at "By SPD", because there is no "auto" option...? And are you sure that i could do it with stock cooling... i have 3 case fans, so that might help... and i dont wanna change the voltage if i dont have to... i know... i suck :)

    2. If overclocking goes bad, and i have to return the fsb to 166, or not as high as 200, then would i leave the ratio at "By SPD" or change it to 3/3, 4/4, 5/5, or 6/6 (because i dont know the difference btwn these... they all seem like 1:1 ratio's to me)?

    Thanks again, i really appreciate it!

    1. I use the 3/3 option so I know without a doubt and it is manually configured instead of having it detected and set by the mobo. If you don't want to increase the voltage and it's not stable you can just decrease the multiplier one step at a time. You shouldn't have to do it though. Adding a little CPu voltage won't hurt either.

    2. If as you put it goes bad, all you need to do is change the CPU operating speed back to stock and leave it all like that. I don't suspect you to have any problems with default multiplier and 200fsb.

    Thanks again, i really appreciate it!

    If i must change it back to fsb of 166, should i change the ram back to "By Spd" or leave it at 3/3 ?

    And, i keep throwing this question out, but why would the BIOS let you choose 3/3 all the way to 6/6 if those are all 1:1 ratios?
    Am i missing something?

    Thanks mtgoat

    >>> EQuito--
    I will just chatter about universal things then-- operating systems, Power Supplies, how to figure out what died when something overheats or the thing will not even post, what fans are best quality, etc.

    Many of the posters HERE will not maybe follow my advice, but I have lots of happy customers. And I can tell you what things tend to go first heatwise (RAM and Graphics RAM, because they are the things not often cooled with heatsinks). So, can offer that kind of thing and plan to stick nose in cuz a virtual blown off nose does not hurt me and cracking my online box would at worst result in my sticking the other HD tray in(legal, box is not a windows box). At best, I will learn some things, which is the other reason I say what I know-- to learn what I can learn if have a detail here or there wrong.

    Knowing what can be overclocked a lot with minimum cooling tells me some things about how well the heat factors were considered in designing our play toy construction kit parts.

    So if I say I would not and ten people say WE DID with this, the same things might be decent for others down here in FLorida who use the boxes in unairconditioned shops to look up car part info, etc. Let's say interested in heat, not a lot of time to play or money to burn on cooling gear or hyperactive fans or cutting tools beyond basics to stress test RIGHT, so keep track of users and the OC sites in part to see what folks agree on. And if can have an idea I think might help will not get too peeved if someone details how to do better-- but "I CAN" is not enough for me. Knowing the details helps me find patterns that the newsgroups alone and tech support areas alone cannot do.

    Let's just say I yearn for an nF3 board when they come out, and a VT800\8237(if those prove out) or i875P board. Probably will not talk too much about RAID or video cards in great detail, but core things I remember like an elephant in terms of patterns.

    So not ever too proud to learn, though am an older dog who has covered a lot of ground in the IS\IT rural farm country. I know, you did not want to hear all that..... :) ;P

    Only 3/3 4/4 5/5 and 6/6 are 1:1 ratio, anything else will run the mem asynchronously and just like you, I also wonder why Abit did it that way. :confused:

    Well, i just read this while doing a quick search on google.. it was on some other forums... but this is what it said...
    No, there are 4/4, 5/5, and 6/6 etc... It doesn't say in the manual, but I'm guessing it has to do with the PCI divider- setting it to 6/6 will divide the FSB by 6 to get the PCI bus speed. You don't want to use 5/5 with your FSB at 200MHz because then the PCI bus wil be running at 40MHz. Get my drift?

    u think this has any validity or is it full of crock?

    thanks again man:D

    Absolutely incorrect. The PCI bus is locked on these boards therefore there is no PCI divider. It doesn't matter at which frequency you run the FSB, the PCI bus will always run at standard 33MHz

    I use 6/6 but it doesn't really matter because as I said before, X/X = 1/1
