Idles look grand, load aint too bad. What type of crash or bsod are you getting?
Click to expand...

Just a restart!

Just tried 4.7GHZ using realbench at 1.280V and it restarted within 10mins.

What are safe volts?

Btw that 81C was in OCCT

( In Occt one core is some 6C higher than the rest at idle, so instead of 31C it's at 38/39, how odd! )
 
Check event viewer round the time of the crash, in particular look for WHEA event log, cpu event id 19. Often an indicator of low vcore. Also, are you raising the cpu input voltage? Might be labeled in bios as VCCIN. Each manufacturer rather confusingly has a different name for it. Typically this should be 0.5v higher than vcore, ie in my case 1.300 vcore means 1.800 on input voltage.
 
Doesn't seem to be much love for the i5 4690 around these parts!

Just thought I'd share my new buid results. Running a reasonable 4.4 at 1.15v and 4.0 uncore at 1.185v, default VCCIN and LLC Medium.


Just pushing it this evening to see what it can do when called apon, seem to hit a voltage wall at 5.0, but will do 4.9 with 1.375v, 1.9v VCCIN and High LLC. Haven't pushed uncore any further yet.

Ah I'll take a look now, just did a 1.3V run at 4.7GHZ, it only got as far as 80C, which in this heatwave is fantastic! My room temp is 30C at the moment :eek:

Cheers Setter

Could you place your image in spoiler tags please.

Looks like a pretty ok chip there, think there is a 4690k owners thread, though havent seen it updated in a while.
 
1.31V , 83C was the highest it got to with no thermal throttling. It also did a two run hash match success. I will retry tomorrow night!

Once these 30C room temps go away, you can knock a big lot of these temps for sure

More stability now for 4.7ghz :)
 
You might see a bit of a temp drop, but tbh with how hot theese chips get in certain programs. A 30 quid air cooler will cool the same as several hundred quids worth of custom watercooling.
 
1.310v = Driver has stopped responding

Although I did have chrome open at the time! Am I supposed to have everything else closed? :)

1.325v = Software crashed

Getting annoyed now :(

AID64 Extreme has been running for over an hour now, how long do I leave it for?

Developer Overclocking notes

1) If you would like to stress your system to reveal a potential hardware flaw or instability, then enable all tests in the System Stability Test window, and press Start. Let it run for a few hours. If it doesn't display any error messages, Windows also runs fine, and your computer doesn't reboot, doesn't lockup and doesn't shut down, then your computer is considered very stable.

2) If you rather want to stress your system from a thermal point of view, to reveal potential cooling issues, then only enable the FPU test in the System Stability Test window, and press Start. Let it run for a few hours. Watch the temperature graphs, where the motherboard temperature should stay below 55-60 Celsius, and your CPU temperature should stay below 80 Celsius. In case you have an Intel processor, then should also watch the bottom graph where the Throttling activity should stay at 0% all the time. If the Throttling graph shows any non-zero activity, it means your processor is overheating. In case your computer restarts, shuts down, locks up or throws a BSoD while running the thermal stress test, then your computer is overheating.

- AID64 Extreme is 2 hours stable!

I cannot get Asus realbench to remain stable, it constantly gives me a Nvidia driver has stopped responding! So I'm going to try 4.6GHZ and aim for lower voltages, using this as a guidance.

Could also be 353.38 related

I will have to go with Raja with this one. Realbench has consistently crashed my drivers at the end of the test when using Nvidia, for several years on several systems. There were known issues with Nvidia and Open CL/GL support. However, when using AMD cards and drivers, this is a non-issue. It's been known for years that AMD supports Open CL/GL better while Nvidia supports DirectX more or less on the same level as AMD. I thought these issues have been resolved long ago, but I guess not.

I never cared to report it because even when the drivers crashed when using Nvidia, the RealBench test still said it passed.

4.7GHz 1.236v, Nepton 140XL, 77C max (volts read from vcore points on mobo)

15min RealBench stress.

Power save states and turbo disabled, all else on AUTO.

New 'in progress' DC build :D
