750W TP

[WojtekGee]

Hey guys,
I've been running into some issues as of late bsoding, and I'm trying to rule out possible issues.

I was considering that this may be a PSU issue, and I've tried to calculate myself and it seemed ok, but to make sure I thought i'd ask you guys.

It's a 750W Antec TP Blue (http://www.newegg.ca/Product/Product.aspx?Item=N82E16817371022)

Asus Crosshair IV extreme mobo, with 955 BE overclocked to 3.9, 1.5125V

8 Gigs corsair xms3 @ 1.5V

Two reference sapphire 5850s, overlocked slightly (i think +50/100 just in the CCC)

and a noctua NHD14 heatsink, with a few case fans and a noctua side panel fan.

One mechanical HDD
CD/DVD writer

CPU does NOT overheat, runs idle at 28C and under full load (stress tests) @ a steady 54-55.

GPUs do NOT overheat, run on full load (stress tests / graphic intensive games) @ a steady 60-65ish (I don't let them get higher with Afterburner)


Is this enough, would this setup cause BSOD issues because of power consumption issues?

BSOD error is atikmdag.sys... googling brings up a lot of issues, lots that are random, and some indicate that it is related to power consumption as well.. so I thought I'd ask

Most likely unstable overclock. The power supply you have is a very good one, and there's no way you should be exceeding its limits.

The thing is that I ran stress test for both the GPU (Furmark) and ram (memtest86) and CPU (prime95), one each night this past week - returning no crashes.

I doubt it can be unstable overclock, but I'll dial back the GPUs to start and see what happens.

I also agree that its likely not your PSU. After years of fighting with ATI drivers, I finally gave up and relegated my 4850 to my HTPC. Do you have another drive you could put a test load on and see if it BSODs on a fresh load?

You may want to ask a mod to move this to the Video card section aswell.

Nah I don't, however I've found that it may have been a setting undervoltage issue with the GPUs.

I upped it to 1187 mV and I haven't had a crash yet, so I'll keep an eye on it.
