Maximus V gene & 3570K - Strangely high stock voltage

[Joni]

Hey,

Just got my V gene/3570K rig together earlier today and now im really wondering why i have such high stock volts (1.268v at gaming load, 1.248v at P95 load ), i tested the cpu yesterday in my brothers rig which has asrock Z77 mobo and with that stock volts were way lower ( 1.178v)

Everything is working fine, just really bizarre that there is such big difference on volts which obviously makes cpu temperatures a lot higher which really aint very nice.

Cleared cmos and loaded defaults but didint change anything.

System details are:

Asus Maximus V Gene ( bios 1309 )
i5 3570K
Thermalright True Spirit 120 rev A
EVGA GTX 680 2GB
G.Skill Ripjaws X 2x4GB 2133MHz
Intel 330 120GB SSD & WD 1Tb HDD
Super Flower Golden King Platinium 650W
CM Storm Stryker
Windws 7 Ultimate 64bit

Thx

Joni

well, that is strange that temps stay low for IB chips at higher volts LOL, but it is good news actually hehe. I've encountered only 1 chip like that so far and not personally. good for you 🙂
if cooling allows try seeing if you can get 4.6GHz stable and where the temps land. vcore could be looking too high I admit, but if temps are fine then go for it 🙂

usually majority of IB chips run HOT even at 4.5GHz LOL, but that is mostly because of very poor TIM application on the CPU die (under IHS). this can be corrected by delidding the chip and using CoolLaboratory Liquid Metal Ultra or Pro compound, some insane drops in temperature were achieved by this. Personally I've seen a drop of 31C under load on one of 3770K chips. However don't attempt this process if you are not feeling confident about taking the chip's lid apart and don't even consider that on poor clocker chips, not worth it.

Yours is a paradox however, hehe, good luck with this one! 🙂

I must say this chip is really strange, did some more testing today and there is insane jump in needed voltage from 44 multi to 45. 4.4Ghz is stable around 1.220v, so there is huge 0.110v jump at voltage it needs for single multi increase which is just nuts.

But another even more strange thing is that my temps are really low for IB specially considering high volts i need, even with 1.340v im getting only 73c,77c,71c,72c at 3h prime 27.7 run with my mid range TR true spirit cooler. With that another 3570k i had in past i got way higher temps ( low/mid 80:s ) in P95 with 4.5ghz 1.175v and had H100 with push pull GT AP15:s on top of that.

i Think im done with this chip now and just leave it to 4.4ghz for daily use as with that i get really low temps, considering the huge leap at volts it allready needed from 4400 -> 4500 i probably couldnt even get it much higher. I just seem to be one of the guys who always gets dud chip.

It was same with SB for me, had 4 different 2500K:s and 2x 2600K:s and only one of those got past 4.8Ghz with reasonable volts, first 2600K was total lemon and needed 1.38v for 4.5ghz and didint get past 4.7 no matter how much volts i gaved it. I think from now on i will buy my cpu:s second hand to get even half decent clocker for change LOL

pffft, haha, it sounds like my luck too LOL. this IB chip I have now is the only good CPU I had in 4 years LOL ... had same bad luck with 2600K (1.57v for 5.0GHz or daily 4.8GHz with 1.43V or so) ... and a few 3770K ... duds or below avg clockers nearly all of them ...

4.5GHz is a very decent clock for IB (similar to 4.8GHz on SB equivalent) and certainly it won't bottleneck even a 680 SLI, so you are golden for daily performance and temps are low, that's a nice touch. you did a good job with the hardware at your disposal, enjoy it man! 🙂

just today, finished building a rig for customer. 3770K under H100 at Quiet mode topped out thermally at 4.6GHz with 1.27V under full load (IBT) with following temps:
a) idle 27C
b) Cinebench load 71C
c) IBT 2.54 load 93C
temps per hottest core.

left it at 4.6GHz for longevity and with Internal PLL disabled, so I didn't have to sacrifice the Sleep ability.
batch# was 3228B, had one of those (personally) some time ago, similar or worse results. batch theory mostly works, but not always (there are exceptions, in both directions).

cheers and have a nice weekend people! Heineken time 😄
