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

So my CPU is crap!! Cannot do 4.6 with less than 1.3v...!!! 😞

yeah, IB chips differ a lot, I had 6 of them in my hands (all 3770K) and I've seen one needing 1.51V for 4.8Ghz (or around 1.3ish for 4.6GHz) and I've seen two that could do stable 4.6GHz with near stock voltage (1.2v) and 5.0GHz with 1.46V ... they just differ greatly ... all numbers at Ultra High 75% LLC.

now generally if I see a 3770K that needs more than 1.15v for stock Turbo 3.9GHz (with Intel spec LLC) I consider it a lemon, usually those need hell of vcore at higher clocks and quickly hit the wall even with decent cooling.

good test is to see what it takes to boot 5.0GHz (doesn't have to be stable, just boot successfully), if it is more than 1.35V vcore (to boot) then it's crap.

ouch, sorry to hear that man ... I had one of those, quickly returned it for exchange ... if the return window is closed, then remember that you can always sell it on ebay and take your chances one more time in silicon lottery. in US we have decent CPU prices, best ones probably in local Microcenter, but Fry's can price match or get it online from newegg, tigerdirect or even amazon (this one allows reterns for a refund, others don't).
My initial chip was average, but it died on my former faulty Z77 board, the replacement was awesome butI used it briefly on same faulty board so it degraded like crazy later even when it was already running on MVE ... took me 3 more chips to find the same batch I had (as second) which was very nice to me, but I found it in a local Microcenter hehe.

now building GB Z77 UDH5 + 3770K + 660Ti for a colleague, seems they gave him a poor batch (3228B, the worst one I had) in Microcenter, but further testing will tell fi this chip is same of differs even from other sample of same batch. it's a lottery after all! certain good batches only increase the chances, but they don't guarantee anything.

Hey Joni, 1.32V is still in the limits though more than normal.. As you and, every1 else here have mentioned, it does vary between each chip set.. Though, I am curious as to, what happened to your previous 3570k? Have you tried it on the MVG?

Actually even 1.32v werent enough for 4.5GHz 😞 Had to up volts to 1.340v to stop random whea errors during long gaming sessions so this is really rather poor chip. Anyway im not hc benchmarker so 4.5ghz is easily enough for daily use so dont care that much about it.

I Dont have that another 3570K anymore, i bought it long time ago when ivy:s were released and it went along with other parts when i sold that rig.

Oh, thats bad.. Sorry to hear that mate.. As long as the temps are under control, I guess you can still use this chip especially, since you do not plan on over clocking to higher clocks.. However, I still do not understand the logic behind this much variance between chips.. If every chip is done by a robo, shouldn't most of the chips be much more equal (in terms of volts/temps/etc..) than, with so much of variances?? Wonder why the quality dips to such levels at times.. Huh.. Just got to live with it eh..

I do not consider that crap at all. Your CPU works just fine as it is or am I missing something?

It's below average result for an Ivy Bridge 1155 to be honest.
4.6GHz @ 1.32V or so is flimsy ... most Ivy Bridge I've encountered personally or in forums, average with 4.7-4.9GHz at such voltage. it's not tragic, but ain't golden for sure 😉

this guy, feniks, trust me, he has done his homework!! 😉

1.32 for 4.9?? Wow.. Thats a jackpot.. Who is this chosen one you speak off?? 😛

However, as long as it servers your needs, I would not call it a crap.. Unless of course, you are into benchmarking and, want to break the OC records.. 😛

mine can do 4.9GHz with 1.37V under full load (my daily on offsets), it can also do 5.0GHz with 1.465V under full load but that doesn't work with offsets only fixed vcore.
I've seen much better chips on HWBot forums and in OCN forums. A fellow OCN member (PuffinMyLye) bought a chip in Microcenter which was doing way higher clocks with same voltage as mine, think of +400MHz higher, forgot his batch # 3229 or 3230. his chip was able to do 5.5GHz with 1.61V while mine can do max 5.1GHz at such voltage on water, go figure the difference 😉

here is the OCN member 5GHz Club chart:
