5960X Overclocking perhaps not going well...?

[DarkSilentSC]

This 5960X has been OC'd to 4 Ghz with VCore of 1.185 + offset of 0.015V

Yet the CPU just gives in after 30 minutes of torture testing via Prime95.

I'm wondering if there are more things I can play around before admitting I got a below-average CPU.

 

Basically the hardware are the following besides the CPU

 

AsRock X99M Killer MB

Corsair H80i

2x GTX 780 Ti

1200W Silverstone Strider Gold Evo

 

I would like to hear your thoughts.

i don't think your vcore is 1.85v mate  also i don't think realtemp is reading your temps right if you were running prime95. you don't want to use prime 95 on a haswell cpu. you should use intel xtu.

Bump the voltage higher than 1.216. I'd assume you can safely go up to 1.3v for extended periods.

Whoops! Edited.

[SeanAngelo]

the voltage says 1.216, try bumping it up

[DarkSilentSC]

Apparently even after setting my BIOS as 1.185 + 0.015, it adds more than 1.2. I'm thinking if voltage config is set to Adaptive Mode, it causes that?

[79wjd]

Just wondering about your basis on the voltage number you just came up with.

Well, 1.3v is perfectly fine for Haswell and Devils Canyon, so I'm assuming it would be fine for Haswell-E

I've over-set to 1.26 before, sure the P95 ran for quite a while, but the temp was hitting as high as 95C! I guess H80i is too small for this beast huh?

[Jumper118]

Whoops! Edited.

ha ha. its prime 95 thats making your cpu overheat if your using adaptive voltage. try a different stress program and keep an eye on those temps. the h80i isn't the best thing to cool a 5960x with.

[Cookie Monster]

The 5960x is a scorchingly hot chip. You'll ideally need something beefier than an h80 to cool that nuclear reactor.

[Najuno]

I have a custom water cooled loop to cool an i7 5930K on an Asus X99 Deluxe.

 

I do not like Prime95 because for me the best way to stress test my hardware is Aida64 Extreme. That being said I´ve got 1,35Volts on the core with a stable OC to 4,625GHz and my RAM are running at 3GHz stable as well.

 

It sure depends on the silicon lottery a bit about how much you will be able to overclock, but your H80i might be a bit undersized for this CPU. With that I wouldn´t go over 1.3Volts. I have seen CPUs die with Prime95 before, please make sure you are not using Adaptive Mode for your voltage.

 

I ran my system in a 24h stress (Aida64 extreme) test and the hottest core was at around 70° Celsius. And sure I know mine has just 6 cores but I´ve got the same TDP.

[awettree]

You may not have lucked out in the silicon lottery, but I have my 5960x at 4ghz at 1.133v. Just a thought, because setting more voltage than necessary can cause an unstable overclock. Also, with my old Corsair h100 in push-pull with Noctua NT-H1 thermal paste I get a max temp of around 75c in prime95 small fft. Temps struggle to reach 60c when I'm rendering. My ambient temps are around 20c.

[DarkSilentSC]

Thanks everybody for sharing your overclocking experience!! Now I am much more familiar with where I'm staged now.

Definitely I got almost an unanimous vote on selecting H80i was not a good choice for 5960X. (I'm in dead end for that since I have FT03 case...)

[runit3]

I wouldn't bother using Prime95 or AIDA64, the only benchmarking utility I've gotten to work properly with my 5960X is Intel's XTU https://downloadcenter.intel.com/Detail_Desc.aspx?DwnldID=24075 AIDA only shows 5 out of 8 cores and my experiences with Prime95 on Haswell (4690k, 4790k, 4770k, 4670k) have been less than amazing.

Like everyone else said, the H80i just isn't going to cut it. Here's a screen grab of my current BIOS settings:

Working on doing an X99 OC tutorial, going for higher than 4.375 tonight via BCLK as it wasn't Cinebench stable using my insane voltage settings, might throw in some offset tries as well.

i'd up the DRAM voltage to 1.505/1.565v on both banks. 1.362 may be the XMP,

but the IMC might need more for 4x modules and the VCCIO would deffo need a

boost from "AUTO". kind of a haswell tuning thing for stable OC.

1.35v is rated on the G.Skill kit, I had to toss all of the XMP settings as they wouldn't load properly in Win or the BIOS. Using the XMP dipswitch on the board worked, but locked the multiplier at 35core/24cache/125BCLK. Every setting is on manual aside from the obscure voltage settings I never had to mess with on Haswell. Thanks for the VCCIO tip, I'll give it a go when I'm ready for another 4.5Ghz adventure.

That's fixed with HW-e.

@Op just up the vcore
