Trying to do a basic overclock setting. PC crashes.

[CudaJoe]

Hey guys. Ive done a lot of research about overclocking so far, followed the How to Guide (article specifically for Maximus VI Formula) and watched LinusTechTips for overclocking ASUS ROG mobos AND watched Jay jay's how to video for doing a basic overclock of the Maximus VI mobos line.

I am stumped. It seems the only way my computer will run if I leave all the settings at default for the Haswell i5 4670K and deal with having 3.8Ghz turbo boost.

All power connectors are connected to the mobo. When I run the RealBench v2 stress test, I will get the following error from windows after 3 minutes or so "SYSTEM_SERVICE_EXCEPTION" and the computer resets.

My build should be in my signature hopefully but if it isn't I will add it in this post. I do know that if I cant pass the stress test on my default setup, what chance would I have at overclocking?

Thank you for pointing out Real Temp to me. Far different temp reading than the Suite III utility. Where does Suite III get its temp from?!?! The temp of the water flowing through the water cooler? lol. Im guessing its a calculated value.

so at 4.2 Ghz O.C. and XMP settings for the Ram 1600mhz - 16GB -9-9-9-24-2T, CPU voltage set to 1.250.

I achieved a score of 65127.

highest Temperature from RealTemp achieved across the 4 cores = 59*C 59*C 58*C 55*C

Well now you have a starting point, increase the core ratio to 43 and test at 1.250v.
If it fails the stability test, then bump the CPU voltage to 1.260v and test again.

yes, I would like to probably try the 4-way optimization but initially I tried that after install and had a bad time. System crashed and required a reinstall of windows... So I havent tried it since but it would be alot easier. I think Im okay with 4.2 Ghz for now. The thing thats driving me crazy currently is I want to change my windows splash logo during boot on windows 8.1 and a neat little utility called "8oot logo Changer" keeps failing to put my new logo up.

I know it works, Ive see the youtube demo video. I just end up with a blank screen everytime 😧

4 way optimisation is not available on the ROG boards, it does something similar but not 4 way op. That is only available on non-ROG boards.

Really?

Then surely this ( scroll down to the the 4-Way optimisation section ) is way beyond misleading advertising?

I'm not trying to be a jackass here, and I have great respect for your knowledge, but surely it either has it or it doesn't, and Asus's website states quite clearly that it does.

Confusing yes?

The board does have 4-Way Optimization as advertised. Digi+ power control, fan control, EPU and TPU make up the 4-Way Optimization. The difference between the 4-Way Optimization on different boards is the manner in which the TPU overclocking is implemented. If you system is crashing when using one of the CPU overclocking presets it is because your processor's capabilities is below the average found after sampling 100's of processors. If this is the case you will need to use the TPU settings as a base and manually overclock from there.

yes, thats the conclusion ive come to as well. So I can try the AI Suite III but not click on that little button called "4-way Optimization" I can just do the performance overclock but not the Extreme overclock feature. So far manually I can do it fine, just requires more voltage to achieve 4.4 Ghz than it requires for other people.

So how much voltage is too much voltage? I am pretty sure 1.500v would be way too much voltage lol. At 4.4 Ghz im in the 1.300v + range and I dont know how high I am allowed to keep increasing that to get more speed.


Also, I havent been able to successfully do a stress test under default settings on my mobo. Is this a bad sign? or is my CPU so overrated that when its in "turbo" mode (3.8ghz vs 3.4ghz) it still isnt getting enough power?

Try to keep it below 1.35V.
