ultimate S939 mainboard guide - tweaking guide ,known bugs, and fixes

[xgman]

DFI decided that they will (eventually release a 939/agp board as well as the pci-x version.

I had 4 asus A8V's (1.2's and 2.0's), and abit a8v and a gigabyte 939, and the Neo2 blows them all away as far as top end and ease of setup. (my opinion) Also Neo2 with bios 1.36 allows me a vcore over 1.9v and vdimm overvolts towards 2.9 with no further mods. Yes it does have bad chipset placement and fan, but replaceable for a few bucks.

You can, but you aren't.... right? I'd be quite scared to put an A64 over 1.9 from all the stories I've read here.

Well I have to put my 2 cents in here about the MSI Neo2 and it runs great on BH-5 and 3700EB and has so far been the best 939 board I've ran so far.

Ditto....I just think folks have sour grapes 'cause they expect an easy OC each time.

It took me a good 2 weeks of playing with different combos to find the one that my Neo2 liked. Once I got the Bios straight and the right mem...I've had zero issues.

Most Neo2 problems can be attributed to folks not having enough patience.

(Except `schr0et's NB fan problem...however that could of been easily fixed.)

So True.

My second 939 mobo was a NEO2 which I got the first week they came out. I grabbed it to replace my Abit 939 board which wasn't working out at all. But, just one day with the NEO2 and I disarded it as a piece of junk.

Then, another month later, after going through 3 more 939 mobos, I returned to the NEO2. And after giving it another chance, it really has turned out to be a splendid mobo.

Some quirks...yep. But life is relative and the NEO2 is the best of a quirky bunch of 939 boards. The work arounds are pretty simple too....once you know them of course.

I actually think there are a lot of happy NEO2 users out there. And, if you look carefully at the general trend of who likes the mobo, it tends to be some of the more veteran tweakers. No offence meant if any is taken by that comment...but it that is actually what I beleive I am seeing now. And there are definite exceptions to the trend.

I have the MSI K8N Neo2 card. Since you guys say that it takes alot of tweaking in the bios to get it stabile, maybe you could help a mate out

I'm currently using 1.36B bios, and a brand new 4000+ (sample) I got at work. Before that I used a 3500+. I've tried it with both 2x512MB OCZ3500EB and 2x512MB Geil Ultra X. Over to the problem. I can't get more than 200MHz overclock, and even then it is not stable. This is with both the CPU's. I can play games for hours and hours, but Prime95 won't go for more than a couple of minutes. Is there some special thing you guy's do to make it stable I've tried everything from 12x217 to 10x260. Hopefully you guys can give me some hints. Another thing. At what temps do usually these CPU get unstable. I'm using a CoolerMaster Hyper 6 w/ 2x80mm to cool it, but it rises to about 55 degrees under load. I'm also using the OCZ 520w PSU. Hoping for some good suggestions from you guys.

Try the following for the 3500+, adjust the multi a bit lower for the 4000+.

Also...try the MSI 1.3 release bios through live-update.

Mem: 2.5,3,6,3 1T 2.80v 1:1
HT: 4x
FSB: 260Mhz
CPU: 9.5x 2470Mhz 1.60v



Mem: 2.5,3,6,3 1T 2.80v 1:1
HT: 4x
FSB: 255Mhz
CPU: 10x 2550Mhz 1.60v



Mem: 2.5,3,6,3 1T 2.85v 1:1
HT: 4x
FSB: 260Mhz
CPU: 10x 2600Mhz 1.65v

it seems like 55degrees is a...high temp. I'm not sure, but 55 seems like a unstable temp for Athlon 64s. I don't own one myself but I would say a 52 degree load temp is good

your prime errors are not cause of the cpu. could be psu, ram or mobo.
