Stability Testing i5 4670K

[Trojan Horse]

I just want a meagre overclock on my chip. I have my i5 @ 4.3GHZ with a vCore of 1.245v. It's a pretty bad chip.

Its ran succesfully on P95 and OCCT (linpack + CPU) for 30m ea (will test for longer, just don't have time to right now), but then I downloaded the new P95 (w/AVX) and though my temps are stable 60c on 100% load, for short times it spikes to 90c for about 30s and then returns. Should I worry?

On all my other tests my temps don't exceed 65c at full load and 35c at idle (fans at 100). When doing work though I turn off my fans and hit 50c on idle - is that a safe temp?

Try using Asus realbench as it will give a more realistic idea of temps.

Look that it spikes at 90.... its in the dangerous level.... well the again do you usually make your cpu go at 100% load ? under regular use ??? i would also install 1 more fan i was overclocking if theres no money for another cooler

Good AVX programs do get recent chips very hot. My hunch is the transistor density now is so great that the die-IHS interface is limiting the effectiveness of the cooler to do its job.

You'll have to accept that at that OC it will spike to very high temperatures under certain conditions, or drop the overclock and make it AVX safe.

Just downloaded the latest PM95 for Win 10 (version 28.9 64-bit) to see what happens to the Vcore on an Adaptive overclock compared to a Fixed/Override overclock.

i7-4770K @ 4.3GHz
H100i cooler with Phanteks MP fans

On Fixed/Override (1.28v Vcore) the stress test added nothing to Vcore, and highest core temp after 2 minutes was 70C.

On Adaptive (1.28v Vcore), the stress test added 0.1v to Vcore (1.38v Vcore), and highest core temp after 2 minutes was 83C (it would have reached higher had I left it running longer).

I can get my 4790K running 'stable' at 4.7ghz @ 1.27v in a number of stress testing programs. I find however that I get instability when playing Battlefront (only game that causes instability!) which causes crashes (whea error).

Got a screenshot of it passing recent Linx or IBT with at least 120 GFLOPs (135 better)?
