I want to get one of the new high end video cards soon and will have to buy a PCIE board for it. I like a lot of things about this one but I've heard of various problems when using it with Corsair value select memory. Unfortunately, that happens to be what I have right now, but I would like to keep using it in the new setup at least for now. It seems that some people have no problems with it and others can't get it to work stably at all. I've heard that setting the voltage to 2.8V or the max async latency to 7 (which is actually the default setting on my current board) can fix the problems, as can updating to a newer BIOS. If you have tried this motherboard/memory combination, can you post about your experiences here?

The other possible issue is with the location of the chipset fan. It looks like a large video card (like the upcoming 512MB 7800GTX) may mostly cover it up. Does this cause any problems?

Also, can this board detect the new 939 Opterons without any BIOS flash?

Sorry if these things are covered in the sticky thread, but I don't have time to read all 1500 posts there.

well, the corsair as you say is hit or miss. since you already have it, no harm in trying. :p

as for the chipset fan, my gtx sent the chipset temp skyrocketing. well, not sky rocketing-still safe ~55c but higher than i like. so i moved the card to the second slot which lowered it back down until i got my nv silencer for the card. now its all good in slot 1 and the chipset ~42c @ 2700rpm.

i'd be prepared to flash the bios on first boot. most likely, you'll have an older bios in the box (3.10 maybe?). i'd get the 623 official on a floppy and just flash it and be done with it :p

yeah I was thinking about that, but I want to put my sound card in the lowest PCI slot and having a dual slot video card in the bottom PCIE slot will restrict airflow. Their new expert board appears to have fixed this issue but the layout is otherwise a bit weird and I bet it's going to be much more expensive. :p

I did some google searches and it looks like this BIOS fixes some of the problems with Corsair memory. Do they still have the 3.10 on shipping boards? I mean, even the 6.23 one is fairly old now.

I will probably upgrade to a 2GB pack in a few months but wanted my current 1GB to hold me over until then, since the games I play now don't use any more. I guess one potential issue might be that my corsair sticks are not from a dual pack and were in fact purchased almost a year apart. Don't know if that will cause any problems.

How loud is that fan, by the way? A lot of people seem to be complaining about the nforce4 chipset fans, especially the ones on the older Asus boards. I haven't heard of as many complaints about this one, but it would be difficult to put an aftermarket sink in its place with the video card so close by.

i agree with rise4310, installing an nv silencer 5 on your gpu will lower chipset temps substantially, as the hot air won't be exhausted onto the dfi cooler. and if that doesn't suffice then you can get an Evercool VC-RE. a number of people on the dfi-street forum have replaced the stock cooler with it and their temps went down ~5-10 degrees, with less noise. i ordered one last week and hopefully i'm gonna get it tomorrow. i would stay away from this new asus x16 sli board because of the slot layout. if you want to sli and also have a sound card, there will be no way to use dual slot coolers on the cards and still get sufficient airflow, unless you have a side panel fan. if you really must have a socket939 mobo now (m2 is coming soon), i would get either the regular asus sli board (good layout), the new dfi expert, or the soon to be released msi diamond plus (sli 16x like asus but much better layout).

Yup. I was using 1GB of PC4800 OCZ and now I'm using 2GB of PC3200 OCZ stuff and both worked great.

i have a PVR card in the lowest slot and it didn't effect it.

its not as loud as everyone says. well, it is if you run it as full blast 7000rpm but if you have decent case air flow there should be no reason to do so.

my 2 dfi's chipset fans run at ~2700 and ~3800 rpm which i control through ITE smartguardian supplied on the driver disk. both have load temps ~48c and idle ~41-42c. adding more rpms doesn't matter at some point. at those rpm's i can't hear them at all.

some people position an 80-92mm low rpm fan to blow over the area and cool it more quietly that way.

i would assume you'd still get the 3.10 bios as the 6.23 didn't become official until august iirc but you may get lucky. there are plenty of modded/beta bios' about that may help you with the corsair so i wouldn't sweat it. you maybe one of the fortunate ones :)

if not it'll spur your 2gig purchase :p

first off, you are getting bad advice from somebody. Corsair VS will not post with Max Async set at 7ns. Must be 8ns or auto.

Corsair VS works just FINE on this board. as a matter of fact, the DFI will OC it FURTHUR than other NF4 boards. don't get frustrated if it won't boot at first on a particular divider, because using dividers requires a bit of tinkering.

try these settings at DDR400, all are in the same order as 704-2bt bios (which you should flash to immediately, i had little luck with other bios):

I'll make three posts here, based on settings I know to be stable for Corsair VS1GBKIT400, YMMV of course:). #1 fail-safe, #2 max oc with tightest timings possible, #3 lowest latency possible.

#fail-safe timings. stable from <200mhz to ~230mhz YMMV. pretty loose timings.
cas = 2.5
cpc = enabled
trcd = 3
tras = 7
trp = 3
trc = 14
trfc = 17
trrd = 4
twr = 3
twtr = 2
trwt = 4
tref = auto or 2048
Bank Interleave = enabled
DQS Skew = decrease
Skew value = 255
drive strength = weak4 (level 7)
data strength = level 3 (this is a MUST)
Max Async = auto or 10ns
dram response = normal
read preamble = auto or 8.5ns
idle cycle limit = auto or 256 clocks
dyn. counter = enabled
R/W Que Bypass = 8x
Bypass Max = 4x
32-bit granulation = enabled

these should get you up and running and allow you to use all dividers

#2) Highest OC with tightest timings possible at CAS 2.5 (YMMV). these got mine to 229.5mhz (306FSB @ 150 mhz divider), memtest86+ stable for over 15 hours, whereupon they hit a brick wall. can't exceed 230mhz stable regardless of timings :(

#3) tightest timings possible for lower latency. works for me from ~195mhz-216mhz or so, and memtest86+ stable 12+hours at 216mhz. YMMV.

Wow, thanks a million for all that info. That's exactly the kind of stuff I was looking for.

On my current A8V board, the VS memory tops out at 207mhz at 2.5-3-3 and does about 220 at 3-4-4, but underclocking it to 183 allows 2-3-2, which is what I have it at right now. The only possible concern is that these are two VS512MB400s, not a kit. They were bought about a year apart as I mentioned before and actually look slightly different. Although I have heard that even the VS kits don't necessarily have identical memory anyway.

I'm not too concerned about memory performance anyway, just want to have it stable with dividers for CPU overclocking.

i agree with rise4310, installing an nv silencer 5 on your gpu will lower chipset temps substantially, as the hot air won't be exhausted onto the dfi cooler. and if that doesn't suffice then you can get an Evercool VC-RE. a number of people on the dfi-street forum have replaced the stock cooler with it and their temps went down ~5-10 degrees, with less noise. i ordered one last week and hopefully i'm gonna get it tomorrow. i would stay away from this new asus x16 sli board because of the slot layout. if you want to sli and also have a sound card, there will be no way to use dual slot coolers on the cards and still get sufficient airflow, unless you have a side panel fan. if you really must have a socket939 mobo now (m2 is coming soon), i would get either the regular asus sli board (good layout), the new dfi expert, or the soon to be released msi diamond plus (sli 16x like asus but much better layout).

I basically want a board that is under $150 or so, has a good layout, overclocks well and is relatively stable (after whatever tweaking is needed) and the DFI seems to be the only one that fits all the criteria. I most likely won't need SLI support, although that will depend on how video card prices look a few weeks from now.

That new A8N32-SLI is getting good reviews as far as the overclocking goes, much better than the other Asus boards, but it's nearly double the price of this board and as you said the layout isn't the best. And I haven't had a great experience with my last two Asus boards anyway.

The latest rumors are that M2 will arrive sometime next summer, which is far enough away that I want to get something in the meantime (mainly so I can upgrade my video card), but still close enough that I don't want to spend a lot of money on the board or new DDR1 memory at this point. Sort of a bad time to be upgrading the motherboard, I suppose.

its not as loud as everyone says. well, it is if you run it as full blast 7000rpm but if you have decent case air flow there should be no reason to do so.

Those rpms don't sound too bad. It's mainly the Asus fans that I have heard all the complaints about, actually. I could try 6.23 or that 7.04 one cobbler referred to.

I'm ready to spend some time messing with the settings to see if I can get it to work, although I suppose I will be out $20 if I have return it and pay restock fees.

Are these boards still moddable to the SLI version, or was that "fixed" ?

actually it depends on how old the NF4 chip is

Nvidia started epoxying both spots on the PCB. they just stick a big glob on there, obvious what they are doing, lol

probably have better luck getting an older one from Newegg, though I just picked up my SLI-D at CompUsa two weeks ago and it was not epoxied.
