You figure this will fix the issues? Reinstalling OS is a tough sell for x46.

It should resolve any OS instabilitys if anything seems to still be going on you can also try the repair OS option using the windows cd...but havto have the cd.

Also even reinstall your intel chipset drivers/windows ME driver if you feel its needed.

One thing I like about win8 is the fast restore option its so nice any corruption issues etc and itll reset winows to default and keep all your files and software.

Okay, there is something that I think is weird happening to me. I will start by stating my hardware/bios info first then describe the issue.

CPU: 4770k Batch #: L315B407
CPU Cooler: H100i in push (PS: I applied rubber washers method on the backplate to ensure better seating of the pump)
Mobo: Asus Hero

Overclocking settings:

Core multi: 44x
Vcore: 1.25v (bios) 1.264v in hwmonitor(during stress test)
Cache multi: Auto (3900mhz in hwinfo during stress)
Cache voltage: Auto
Vrin : 1.85
LLC : level 8
CPU power phase: Extreme
SVID: disabled
Internal graphics: disabled
Cstates: On (c7 short)
Other setting are left untouched (stock/auto)

Now my issue here is that when I run Prime95 27.9, temps spike to high 80's after 25'ish minutes in blend test (90 max) and will reach those temps much quicker in small FFT but I didn't run it for alot of time fearing that It will damage the CPU. (ambient 22 C, fans on max speed) Other stress tests don't produce this much heat. Aida64 and x264 for example run much cooler temps.(mid 60's as average 73 peak) Even IBT standard max temp was 84C. Idle temp is 28 C.

Are those temps normal for H100i and 1.25vcore ? I find it very strange looking at other people having the same cooler and pushing much higher Vcore or even the same vcore but much lower temps.
I pushed 2h aida64 with 45x on this Vcore but I haven't gone through more tests. (IBT X264 Prime)
I'm more concerned into solving this heat issue first before proceeding with overclocking. I'd appreciate feedback on this matter.

Yes, that's completely normal. On a ~h100i or high end air equivelant you can hit 100v by ~1.2v with some tests. That's why there is favor for stability testing with x264, or when other stuff is used, to do something specific like prime 27.9 custom fft 1344-1344. i7 is hotter than i5, at a low temperature OC it's like ~7c difference and expands towards like ~12c hotter in my experience as raw temperatures get higher and further from ambient

If you're testing with something intensive like prime 27.9 fft 1344-1344, you can probably test that with HT disabled then re-enable HT and expect everything to work fine, also

Your chip is very close to the one I rescenlt got almost same batch and same overclock results....

Keep this in mind a lot of the high overclocks and vcore you see are guys that have delidded the cpu which is the act of removing the IHS from the chip and removing the glue that binds it down ulimatly removing the gap that causes heat to gather under the lid and not properly exit through the lid.

Now even with 1.25v without delidding can result in high temps keep in mind the tjmax is 100c so essential yanything below is fine.

also not a fan of prime95 but of xtu

I am currently not delidded but I have considered that those people might have delidded cpus, however i have seen non delidded cpus doing much better in terms of temps/voltage on the h100i which has struck doubt in my system. I might just have a really hot chip and everything is normal, but I would like to hear more feedback from overclockers to be sure and have peace of mind.
I'm considering delidding in the future with CLU once I am certain that everything is working as intended and nothing needs replacing CPU/Cooler.

I don't favor Prime actually, I only tried it to check the temps. I usually stress with AIDA64 extreme, X264 and IBT standard. I'm gonna try now XTU since alot of people are using it and will see how it goes.
Btw, I never compared my temps to an I5, it will be lower of course.
Thanks for the tip of turning HT off, I didn't think it wouldn't affect stability.

IBT is worse than prime27.9 fft 1344. I don't know a lot of details about XTU bench but it's likely hotter, too

I can confirm degradation/breakin time, i started out @ 1.255v VID for a 4.5 clockspeed. Stable. Now im up to 1.300 stable in bf4. So i thought, last night i had a 0x000007e. *** is this code for???

Hard Disk or RAM issue is generally associated with 7e BSOD's

Try running chkdisk to look for bad sectors on your HD and run memtest as well to check for RAM issues

+1 0x000007e is usually Hard Drive related.
