Just spoke with Smokey, who does some beta testing for Epox. There familiar with the Vcore bug and are working on it :D
Hopefuly the fix this sometime soon

I've been getting that for a while as well. I prime for a while, decide I want to check my email, and boom BSOD then blank screen. Hard disk stops spinning, it posts, finds my HDD and it starts spinning again and it boots up.. Whats going on? Why do I always get stuck with the bad stuff. I swear NewEgg is sending me refurbished stuff. My Clawhammer came in a retail box with tape holding it.Quote:

Hopefully a bios issue, but have no faith in it anymore.
Can you explain this? 4 hours prime95, and then BSOD...i can not...
WIred the mobo up today and put a active hsf on it. I checked the chipset revision and it is indeed a2
Also, my vcore is overvolted at stock about.5 but it does not fluctuate....maybe like 1.59-1.58v
It's pretty stable now here too. I flashed with 5-14 and left the voltage to default in the bios and am using the VR only to adjust the core voltage.
USDM is giving me a little fluctuation, but only a small step 0.016V sometimes 2 of those steps. But I measured with my multimeter and got only differences of 0.002V.
The difference between idle and load is bigger though. Could also be a nice feature, but then we'll have to know how much it goes up. I don't like it if I don't know how much my proc is gonna get under load.
There's a new version of UDSM available btw, It should work with negative temps, but I can't get it to work :(
the latest usdm sucks :(
Epox and the voltage issues :(
i'm also getting reboots, and i can't understand why????:(
I dont know.. Maybe you guys are overclocking too high?
No probs whats so ever with the 5-14 bios.
Might be the chipset voltage and heat.
Is anyone using this board with a Tagan 480W PSU ?
getting kind of tired of this board.. I can prime, play, bench for hours and stil i get random bsod' s and sometimes colsboots not work, i have to restart.. :/
and btw theres no way for 300htt here, anything over ~290 hangs up.. and guess what.. 2x ldt doesnt work. and well, vcore jumps pretty good :rolleyes:
With bios 15-4 I get better results with 4 x HTT. with 3x HTT I could pifast upto 287 x 10. With 4x PiFast ran with 289 x 10. Strange....

Dunno what exacty causes the spikes in idle mode, but loaded I get more spikes. First I tried running prime, but that wasn't giving me enough cpu load (less the 50%) Super Pi worked better for testing vcore with 100% cpu load...
I can't get the VCORE to stop undervolting nomatter what BIOS I use. Sure the "BIOS" and other software says the VCORE is fine, but my multimeter disagrees. At "1.7V" in the BIOS, depending on the BIOS, I'm getting anywhere from 1.31 - 1.45V on the multimeter idle, 1.28 - 1.3V under load.
WTH?
Is your processor hot? You might be measuring it at the wrong place.Quote:

i was having the same problem too...
do you have vcore mod in place?
i noticed mine dropped like yours to 1.4X when the vcore mod accidently fell off..
tried another bios and same result..
finally just redid the vcore mod w/o adjusting pots and everything was fine again...
I haven't modded anything. There are two coils above the power connector. I'm measuring at the top coil. Is there a better spot?
Flashing to 14-5 and clearing CMOS after that did the trick for me.
So it will probally do it for you too ;)
I'm on that BIOS right now and I'm still stuck. I'll flash it again. At what point do I clear the CMOS? Do I load the Optimized Defaults before or after I clear the CMOS?
Flash the bios first,
reboot your pc and shut it down
switch off power, remove the battery and place the jumper in the clear position....
reinstall battery and place the jumper back and boot your pc.
That did it for me ;)
Nope :( Didn't work. Maybe I'm measuring VCORE wrong? I can't see how I could be doing it wrong, but it's possible.
Some mosfets give different readings :shrug:
do you or anyone know which mosfet to measure to read the vcore voltage?Quote:

Well, got mine up and running a couple of days ago; and I must say that I am pretty happy with this board. I haven't had a single cold-boot problem since I got it. The only problem I've noticed so far is the vcore fluctuation, but it isn't really that bad, and it only fluctuates up, not down. Still running the shipped bios though. Running 250x10 atm, with mem 1:1. Haven't tested the FSB much further, but it seems like the ram still wants to go a bit more lol. This is my first a64 rig, so I need some more thinkering time with it ;)
Anyway, one question: Why aren't there 12v and 3.3v sensors on this board? Theres nothing in the bios, but sandra found something, and reported back 10.5v on the 12v rail :P Measured with a multimeter, which said 12.05, which seems right.
Well, I'm starting to think that the coils are not the correct place to measure VCORE. I looked at the VCORE mod for this board and started taking measurements at the various pins. The first pin in the upper left hand corner with the board installed (1? 2?) shows the proper voltage as shown in the BIOS. It goes up and down when I change the BIOS, so that's the pin. I don't know where else on the board I can check the VCORE, but I'm not going to use the coils anymore. They're obviously not correct for my board.
Uhm, another question: What is that feature called "system performance" under the power bios settings? It can be set to Normal or fast. WTF is that?
Also, how much chipset voltage is "healthy" for these boards?
Hi @ all.
First I want to excuse me for my bad english (I'm swiss).
I've a quite big problem with my Epox Epox 8KDA3+
I've bought a new system:
- Epox 8KDA3+
- A64 3200+ Clawhammer c0
- 1024MB (2x 512MB) DIMM DDR PC400 CL2 KINGSTON HyperX (KHX3200AK2/1G)
- be quiet! Blackline 450 Watt 2 fans
- Plextor 712A
- SEAGATE Barracuda Serial ATA V ST3160023AS 160.0GB 7200Rpm 8MB SATA/150
- case with 6 fans
- Zalman CNPS 7000-ALCU
- Powercolor x800 pro vivo
I would also have a Creative Audigy 2 ZS, but it isn't in the pc yet.
My problem:
Sometimes the just shuts down. Sometimes after 5 minutes, sometimes after 300 minutes. It's like someone would remove the power plug. I've I remember right, some of you have had (or still have) the same problem, am I right? But strange about my problem is that that doesn't happens during im in a game. For example: Yesterday I played for 1 1/2 hours Far Cry (with the highest detail grade, without problems). Then I had to go. So I started the demo mode in far cry, to test, if it will shutdown. But, surprise, when I came back after about 4 hours the pc was still running. I wanted to get back in to the game, to continue. But, surprise again, the pc shutted down exactly when I pressed the "Back to Game" button. After that the pc didn't even got up to the Windows! I had to wait about 15-20 minutes and then it runned again. I try to fix this problem since last friday, when i started the pc the first time. And yesterday night the pc already shutted in the Bios (!!!) after 5 Minutes.
I've tried out all available Bios. Atm its the one from the 16th July.
I've also tried out, all ram slots, or just 1 ram. Didn't helped.
I've the newest nForce3 driver. Cat 4.7.
Can you help me?
Best regards Tscherny
edit: I forgot ti ask: Why do the last two bios versions (7.9; 7.16) not support the Coll'n'Quiet option. Or is it automaticly disabled?
just got an idea! maybe the chipset gets o hot and unstable with that little stock cooler?
Can some one please upload the 5/14 bios? cant find!
