XFX 780i unstable @ stock settings

OK. So long story but I'll make it as short as possible......

Machine specs.........
XFX 780i
Q6600
Thermalright 120 Extreme seated with Artic Silver 5
Duel EVGA 8800GT's KO Series
Crucial 2GB Ballistix Kit
Crucial 4GB Ballistix Kit
4 10,000 RPM 150GB HDs in RAID5
1 10,000 RPM 74GB HD
1 Sata DVD R/W
PC Power and Cooling 1KW PS
3 LCD Monitors
750VA UPS on Monitors
1500VA UPS on Tower


Parts RMA'd since troubleshooting........
motherboard, PS, CPU, 3 sets of RAM

So, here is the problem....

After RMAing all these devices my problem still persists. I can not OC and become stable and I can not run things at stock and still be stable.

If I OC I get stability for between 5 minutes and 2 hours on Prime95, if I don't OC I get stability for about 5 minutes and 1 hours.

When OC'd I get a bluescreen and the system has to be shutdown (Power killed) and when I'm not OC'd, the system reboots and I get a CMOS checksum error and the CMOS clears on its own. This is with a Prime95 stress test.

Any ideas because I'm fresh out.

Let me know if I'm missing anything.

Oh, BTW, If I run Memtest86 I gave no errors. I RAN for 18 hours without error. Only Prime95 causes the system to go down or 6+ hours of using the machine.

In the BIOS either Reset Configuration Data or Load Optimized Defaults. Change only those settings / Enable only those devices absolutely necessary to boot into Windows, and don't alter any voltages or RAM timings. Use Core Temp to read the VID of your chip (w/ both CPU Thermal Control and C1E Enhanced Halt State set to Disabled), and again fill out the BIOS template (enclose in CODE tags, as it makes for easier reading).

Edit: If you haven't already, remove completely the 2x1GB sticks of RAM from DIMM's 3 and 4, and install the 2x2GB sticks in slots 1 and 3... regardless of whether Memtest passed previously or not. And I assume you've already installed the latest nForce v9.64 driverset for Vista x64...

http://www.nvidia.com/object/winvista_64_9.64.html

before adding all the extras and trying to overclock you should be running with minimum hardware. cpu, memory, 1 gpu, and HDD thats it. then add the extras and the instability will be much easier to pinpoint.

with temps being 50c roughly in bios theres only so much your going to do ta boot

I am running tests with your recommendations, I will return with the results but this will (hopefully) take some time.

Anyhow, I thought I'd update you guys and let you know that I clocked everything back to stock. I disabled all power saving and OC features. I have currently run 17 hours without error with Prime 95 and had no errors. I will run further tests and narrow down the problem so that if anyone else run across this issue then hopefully I might be able to have a resolution for them.

Well bad news. Things are once again going south. I disabled SLI memory and all the power saving settings and have been running at stock everything and the system is really acting up. It has been giving me a BIOS checksum error when I tell it to restart and when the system decides to come back up and start running the CMOS has to be setup again because the BIOS error cleared it.
I also contacted XFX tech support via the phone and they gent on the phone said I should loosen my timings on my RAM. The timings were already sitting at 5 5 3 5 18 and are capable of 4. So we loosened them to 6 6 4 6 21 and still the same crud.
Quite frankly I'm thinking of trashing this board and going with one of the Asus's, one that is reported as stable. Of course I'll RMA this one first and wait for the new one to come back in the box and EBAY it.
So anyone else have any suggestions?

Well an update.......

Still fighting stability issues and here is what has been done........

Video cards have been swapped. One removed and machine tested and failed, then the other put in place and the machine tested and failed. Crucial RAM has been removed and RMA'd and temporary Corsair RAM has been put in place and machine tested and failed.

I just don't know what to do anymore. I have all settings set to stock besides the spred spectrum stuff disabled and power saving features disabled.

The MB, CPU, PS, and RAM has all been RMA'd and still I can not achive stability.
Could it be because I'm running Vista Ultimate x64? Could it be that my PS is bad and the manufacturer had a bad batch?

Any ideas because I'm stumped. I will be testing with WinXP 32 this weekend and if it fails then I'm going to rip the whole thing apart and RMA every major part so I can start with fresh hardware.

Well an update to all my problems.....

I just recently replaced both of my EVGA 8800GT KO's and my BSODs went away but now I'm getting random lockup/freezes. For no reason it'll lockup and I'll have to reset. I can however expidite the lockup by running prime and running a small fft test. Doesn't matter if I all stock everything auto or running at my current (and very nice) 3.6Ghz with an idle of 38-40C and max of 69C (Air cooled).

So I've about had it. I'm tired of the NVidia BS I've been seeing all over the web where it seems that many are having this freeze/lockup issue and no one can resolve it.

If anyone has any suggestions now that I've fixed my BSOD issue then I am all ears. I'd love to have this thing at least 80% stable.

OK, so I guess I'll post again here and just let those that read this post know that the problem with all my BSODs was the 2 video cards. Don't know how or why but both were bad and both were replaced. I no longer BSOD but am trying to stop system lockups. I stabilized my system @ 2.4Ghz with 1.28v and am now moving on to bigger and better clocks.

You never did mention what the VID of your chip is.

Well, you appear to have swapped everything out already.

So, whats left? I suggest testing without your UPS.
You need a smooth sine wave. A ragged A/C input or
voltage and amperage issues could easily cause your
indications and it seems to be the only variable left.

I hope I dont run into any of these problems, I just setup my XFX today, I Switched from ASUS to XFX because ASUS gave me all kinds of problems.

I had one of the top of the line ASUS boards and it was never prime stable.

I havent run Prime on this one yet, but so far so good, I am running at 3.4Ghz with no problems as of yet, just some weird sound issue...

Sorry it's been so long since I posted an update. I basically forgot about this post but since I have solved the problem...

So with everything swapped out the problems persisted but I dealt with it because I needed something even if it only worked so so. Then I built a buddy of mine a new system with the EVGA E758 and liked it so well I built myself a new one and RMA'd the XFX board.

Upon receiving the replacement back it was DOA with a bad BIOS so I RMA'd that one. Upon receiving another replacement it was just DOA so I shipped that one back and told them to not ship it to me without testing it, I do NOT want another DOA. Upon receiving that one it worked and everything worked fine. All the BSOD errors went away, everything ran smoother, cooler and better.
Bottom line, it was a bad MB which cost me around the ball park of 150 to 200 bucks to get figured out and fixed.

When all was said and done I sold the POS and boycotted XFX. I will never own another XFX anything again. They need to get their quality control updated and need to incorporate cross shipping.

Sorry XFX, but you have some work to do before I consider you as a hardware provider ever again.

Thank you EVGA for providing 100% customer support without question. EVGA has gone the distance for me with cross shipping and no more that 30 minutes of down time.

My current setup is as follows.....

EVGA E758 Tripple SLI, i7 2.67Ghz Quad Core OC'd to 4.064Ghz, Tharmalright Extreme 120 Copper heatsink, 12GB of Mushkin RAM, two NVidia 8800GT KO's, one NVidia GS450 Superclocked, 4 10K RPM 150GB WD Raptors in a raid 0, PC Power and Cooling 1KW PS and a draw of 500W on average from the outlet!!!

I have replaced my motherboard once with EVGA thus far due to a known intel chipset issue that causes the keyboard and mouse to act very strange. As I said I had 30 minutes of down time and some frustration due to a laggy keyboard until the board was swapped out.
