If it passes memtest then its either cpu or gpu, gotta narrow it down....
Passed 9 passes of MemTest86+ with zero errors. This system rocked with the i3. And it's stable until I enable C3/C6.

I think it's board + GPU combination.

I've recently discovered than when C3/C6 states are Enabled, the GPU fan spins up and down quickly (just like when you bootup after a CMOS clear) between periods of 15' (eventually dies with driver error or freeze) while running Windows.

Also, Linux eventually crashes (e.g: video frozen while other activity ok).

This does not occur without the C3/C6 states.

From this description, what about some form of PCIe power problem?

My brother has a good ol' HD4850. Maybe i'll take that and try.

Additional data: Linux halted! And this is WITHOUT C3/C6!!!

*** ???!

I'll run MemTest+ again, I don't know where to look, really.

10 hours of MemTest86. Zero errors. Memory problems discarded.

Goddamn, I had the exact same mobo as you and it finally quit on me after about six months or so. I got stuttering and freezing when trying to install Windows after swapping out my GTX 460 for a HD4850. I would point my finger at your mobo for the issues, esp if you've already cleared CMOS then restored the settings you want to have.

(and to complicate things it turns out my GTX 460 had issues of its own, but I always had minor issues with that mobo - occasionally not displaying an image on boot, necessitatign a CMOS clear - one time out of nowhere i had a BIOS checksum failure that made it go into failsafe mode to reload an old BIOS - and the final indignity of the aforementioned stuttering and freezing)

Look I got borrowed a new PSU. With the i3-540 I used 4 pin ATX 12V, and installed the i7-870 with the same 4-pin connector.

I'm with a newer CM 500W with 8-pin (EPS12V) connected to the board.

My linear reasoning was: if Turbo is draining more power from the board, may be the 4-pin connector plus a **** PSU is the problem.

Go figure.

I'm testing now.

I doubt it will stabilize my system but who knows. Coolermaster PSUs range from very good to crap.

And I don't know about your experiences with Gigabyte, but my brother built a new i5-2500 system and suffered a lot of problems with standard components, no OC, 1333MHz kingston ram. All market standard. And the Gigabyte refused to work properly.

Finally got the board replaced and the computer is running without flaws.

Thanks for your help.-

Crashed again.

I'm starting to hate this thing.
post #47 of 53
Oh, and I wasn't even using the fanciest CPU - just an i5 760 which hasn't got the hyperthreading but does have Turbo. And come to think of it I had turbo turned on.

That said I was using first a Cooler Master 750W high-end PSU with a 8 pin CPU power, then I switched it into a different case with an XFX 850W which most definitely has 8-pin.

I even changed heatsinks to be sure I hadn't messed up the CPU with the screws on a Hyper 212+.

As you can see from my sig it's now sitting on an MSI board which I bought months back and finally got around to assembling into my case. The system is beautifully rock-solid with the HD4850, and I'm going to swap in my GTX 460 soon and stress test it again to really see how it rolls.

Crashed.

Trying another option:

Did you try to use the PCI-E 4x? I've moved the HD5770 to the x4 slot. The board whines and buzzes depending on GPU activity.

I don't care about performance loss since the 5770 won't exceed a full 16x PCIe bandwidth anyway.

No faults yet. I'm praying...

If this fixes it, no doubt that this MB has some problem with PCI-E 16x devices, according to all the complaning and *hatred* I saw when googling about these issues.

Huh! Sounds like the P55M-UD2 might be a bum steer then.

You may have said this already.. but what if you leave C3/C6 disabled in BIOS and run Prime95 (custom settings, 3/4 of RAM) for 4+ hours?
