post #101 of 428
Bcdedit nx bcdedit pae google those .try to find ms article about it.dep is a protection xd is Intel on by default or nx is amd for 32 bit ,so technicly all is ok since a lot of us have w7 64 bit?did you plug a USB key of a few GB?then pae is back active.not sure for the 2gb USB drive if it enable pae,but more then 4gb,(I update bios via USB drive )activate pae back each time.i loose HD each time why?you would be surprised where 32 bit code hide and often not in the proper memory.dep step in and block this.annoying?you wouldn't believe

Yes I did with no success

Quad Fire Using the right display port on the GPU and the other active adapter and left monitor - 3dmark11 extreme - PASS
Previous tests
All cards individually in eyefinity mode - Heaven, furmark, dirt Showdown, other games... PASS
yes thats what I was having in mind, should I go with the GHZ edition BIOS and leave it that way? or flash it with the XFX black edition at 1000Mhz Core
I need a tutorial to flash the BIOS, I never did this. except on my Geforce 3
So it's definetely eyefinity. Try both DP -> DVI's for eyefinity? 2 monitor

@ Nemesis, my VTT is at 1.25 V and v dimm is at 1.5 ( its not overclocked, stock at 2133Mhz (1.5v) should I raise it.

Single screen power load =/= eyefinity power load. Turning Eyefinity on is going to greatly increase your GPU usage, especially in a quadfire situation, because all four graphics cards are processing several times more frame area than just on a single screen. it puts more load on the graphics VRAM and on the PSU, which still leads me to beleive that your 3.3v is starting to fluctuate just a slight bit too much and cause your ram to go Unstable.

Is the 3930k a C1 or C2?
Either way you shouldn't need that much VTT if your ram kit is 2133 stock . If it is a C2, having your VTT at 1.25 puts you at risk of burning up your IMC. i would try raising your vdimm to around 1.52-1.55 and drop your VTT to 1.2 or under if you can.

EDIT: actually, now that i think about it, it might not even be related to the PSU, but this type of crash is definitely RAM related. Now, due to what i say above about the C2 stepping IMCs not liking more than 1.2v, i dont put mine over 1.2 at all, and i know my ram is a slight bit unstable. I can run games single screen fine for hours, but if i fire up JC2 in eyefinity it will eventually crash (in a lockup just like what you are describing). hence why i beleive it is something to do with your ram. i think you would do good to try 1.55vdimm to start off with. if you are running a C2 stepping 3930k, drop the vtt down also.

Oh and DEP= Data Execution Prevention. dont think that has anything to do with his issue drbaltazar......

If it is ram crash why does it still do it on while loading defaults on the MB ?

I just played 2 hours of BF3 in eyefinity, hell the Jet scene was awsome, especially the begginning . After 2 hours, bang, freeze with no sound, again...hard reset.



@Nemesis : Yes I have C2 Stepping. I will try this in BIOS

I will Prime95 with vdimm at 1.54v and Vtt at 1.15v (VCCSA at 1.14v but with LLC at 1.175v) tonight. Blend with all available RAM

I don't know why I didnt think about raising the DRAM voltage before when I always got the BSOD 0x9c, which, I state where you see that all around the net about x58 and x79: "0x9C = QPI/VTT most likely, but increasing vcore has helped in some instances".Maybe this is my problem.

Yep, that's what I was thinking... When my old Antec 1200 died, it could no longer run trifire and quadfire.

Something you can try to nail it down is run trifire then quadfire and underclock everything. This will obviously reduce the load. See if it still crashes.

Mine Resets to default every time it does this too, Says: "overclocking failed, enter bios to re-input your settings" or something like that

I pulled enough power out of that thing to pop a 15A household breaker, more than once wink.gif

There's a reason my load testing lab uses a 20A dedicated line, and this exact PSU is that reason. If it's not shutting down, or the breaker's not tripping, it's simply not overloaded.

A friend of mine was having his his computer crash while playing bf3, turned out to be the PSU. Granted it was a several year old BFG unit, but youd think being 800w it would handle a single 580 easily.
Just because youre pulling a bunch of power from it doesnt mean its regulating the power as well as it does when its not under as much load. im still not saying its bad, i just think its a possibility that the 3.3v could be going slightly out of spec. Im not saying that is the definitive answer.
the only other possibility that I can think of is that maybe he doesn't have his ram set right for full stability. Eyefinity also stresses other components (cpu, ram) more than just a single screen would.

All I can say is before I sold it, I personally tested it using the same gear the factories do... two SunMoon load testers (one's not big enough to test this mammoth on its own) and a $2k oscilloscope. The 3.3V measured the same way it did in the review.

The PSU is the last on my own list of suspects. I'd rule out everything else first. I'm thinking drivers or RAM. If it did turn out to be the PSU, I've got another 1475W built by another OEM to send him. But I don't think it would make any difference in this case.

BFG? They were good for a while, when they had jonnyGURU helping them, but only for that little while. I'm not very surprised to hear that one.
