Windows 7: Crashes during heavy gaming loads, no BSOD

24 Jan 2011   #11

Windows 10 Pro x64

Use OCCT to check your components including your PSU
It will check your system stability and report any errors with hardware

Haven't been able to change heatsink yet. Will come to that friday when i have time, will also upgrade cooling with sidemounted fan. However OCCT runs nicely on CPU test but crashes on PSU and GPU, in a matter of minutes.
GPU: MEMTEST is unavailable (?). Error message said something about couldn't recognize memory, unfortunately I can't get the program to display the error message again. Will try a reinstall of OCCT later.

I'm guessing this could have something to do with the amount of heat generated during these tests?

All help so far is greatly appreciated as i have little or no knowledge of this subject myself.

I'm attaching files.

Most probably one of these is the culprit(most probably the PSU), take out that GPU and try to replicate the same issue in another PC
As for the PSU, check the cables for any defects

Your heatsink could be generating too much heat

As i understands it the PSU test stresses most components on the motherboard. So my vote is on the GPU. Especially since I have recently discovered that the D601LED is lit at all times, wich indicates critical core power. This is apparently a common issue on 4870's across a range of PSUs and components. The problem is related to overheating of the voltage regulators. GPU-Z detects the following VDDC phase temps: 55C, 57C, 70C and 57C.

The cards is hot by default but 70C idle seems very high. I'm going to try upgrading the fan on Accelero S1 r2 GPU cooler to a more high-revving one, there is already adequate cooling in the form of a large copper heatsink on the voltage regulators beneath the fan and heatsink. I'm also going to try with another graphics card just to make sure, but if this doesn't work I'll throw in the towel and buy a new graphics card, 5770.

Thanks for your help and if you have any more pro-tips I'd be happy to hear them.
