hi this is my first time coming here to ask always came to read so here it is :
i have a core i7 920 d0 and i need it to run @ 3.8-4.0 with low temps/volts and even with the auto i get high temps/volts and BSOD im runing it @ 3.9ghz every thing on auto in cpu-z i get 1.328v and 1.360 on load and its not the other way around anyways 1.3+ for a 3.9 or a 3.8 isn`t this too much for a d0 i just cant get it to stabling any how what should i do this is my specc`s :
MSI X58 pro-e- evga GTX 216 260sc-FSP bluestom 800W Quad Rail +12V 90A-Microsoft sidewinder/steelseries mouse pad-Bloomfield i7 920 D0 @ 3810 190x20 ~ 4018 211x19 1.328 V (auto) with Thermaltake frio (lowx2 fans 50% push/pull) - 6GB transcend pc-10600 @1333- ocz vertex 60gb os-WD 2x1TB all in Thermaltake M9D mid tower case .
i hope than i can get some help like i saw others get :)  :)

Don't underestimate how far you have overclocked that chip, 2.6 to 4ghz is a mean feat, just because tons of people doing it and its now become "easy" with the i7 doesn't mean every single person will be able to achieve it.

Taking my i7-920 from 3.8 to hit the magical 4 I had to start getting real silly with the volts. Pretty sure i'm manually set at 1.42 at the moment (can't remember off the top of my head) and obviously as you start needing to lap on the volts your temps are going to go up just as fast. I think 1.32v is too low to achieve 4ghz on a 920.

To start off i'd leave off the auto voltage and manually set it.

211BCLK is a huge base clock. Plenty of people have said they have had issues getting over 200. Turn speedstep back on or try another combination of say, 191x21 (which is what i'm at). I also have none of the advanced CPU features disabled at all, and i'm fully stable.

Won't let me edit my post, dammit

What I was going to say was, you say that "isn't 1.36" too high for a d0? Yes, it probably is a little high, but what a chip needs...you're going to need to give it.

Are you sure it's instability due to cpu vcore? What is your qpi voltage? If your BLCK is 211, what is your ram running at?

thanks for coming back to me so fast :D  :D  but sheesh i feel like im under attack :kaola:  :kaola:  naa :love:  :love:  im runing it @ 3.8 now with auto 1.352v on cpu-z ra, running @ 1524 9.9.9.24 (1.5v) all others QPI and stuff are on auto too 190x20 with turbo off only C is on all others are off and its not working well it hangs and restarts with BSOD on prime95~linpack test`s and im getting high temps with that 82c and today is a cold day here 6c outside :p  yes the frio fans are on 1100rpm but on 2k its only a 4c deferent so to my ears its not worth it :kaola:  :kaola:  so im sure on lets say low 190blck will it is kinda in limits im needing a lot of volts now i might not have the golden cpu im welling to stale with a bronze one as long as it stays sold :kaola:  :kaola:  if you get what i mean so im looking for a way to lower this temps and i might even lower the speed a bit if thats what it get but i need it to be in good volts so i dont feel all that riped off :cry:  :cry:

ya i know what you feel now :p  :p 
p.s i ran the rams @1800 on 1.5v and they worked fine so on low 1524 they r ok for 1333 rams

First off all... DON'T USE AUTO FOR SUCH A BIG OVERCLOCK.

*ahem*

Ok I don't mean to "yell" at you, but like blacksheep said you're adding well over 1ghz to the chip, that's a LOT and if you've read any amount of overclocking guides they will all tell you to do it manually and test it.

So, first off, I can see one issue. If you left it on auto then I'm guessing you have Turbo enabled too. That is most likely giving you problems at such high speeds. Turbo isn't that reliable over 170 base clock... I have it at 177bclk but for my CPU/Mobo that's the absolute highest I can go with it.

Disable turbo.

Secondly, you have Vdroop under load. Once you turn off turbo boost, turn on Load Line Calibration. This will give your CPU constant voltage.

Once you do that, I highly recommend you set 200bclk and start at 3.6ghz. You want to adjust Vcore and Vtt/IMC/QPI (same thing just different mobos call it different names). I'm just guessing here but 1.32 Vcore 1.25Vtt should be roughly what you need.

If that runs fine, increase the multiplier to 19x for 3.8ghz. Try at the same voltages. If that's fine, try 4ghz.

If it BSOD's, increase the voltage a little bit, like 0.01V Vcore. Then 0.01V Vtt. Test after these changes with Intel Burn Test or Prime 95 or whatever you want to use (OCCT, LinX...).

And yeah underclock the RAM so that it will definitely not be an issue. Just set it to the lowest multiplier and sort it out later.
March 9, 2011 4:37:17 PM

OK ^^ well do and get back to you asap and for my mb it dont have llc or vdroop controls and i dont have turbo running trying it will all off first and trying to turn one thing on at the time vtt=qpi in msi pro-e ^^THANKS FOR REPLAY !! ops caps :p 
March 9, 2011 9:53:50 PM

sorry im back so i tried it and its working so far 8min on linpack but it looks slowish and hangs im waiting on it to crash :p  its get 75c max
next what should i do :p 
a c 100 K Overclocking
March 10, 2011 2:18:40 AM

75C isn't bad. If it passes around 20 passes at a high stress rate, like ~2gb used RAM, then you should be stable. Some people suggest up to 24hrs of Prime95 but... linpack is a lot higher stress and it's faster.

Anyway so yeah, if you're stable you want to lower the voltages to the point that it's unstable and then just raise them back up a tad to the last stable setting. That's how you get the coolest temps. Then, get the RAM to go as fast as you can.
March 10, 2011 2:06:04 PM

so now im @ 20x189 with 1.280v 1516ram did about 30min on linpack so far no crash temps are 69.68.66.63 on realtemp btw i use OCCT linkpack so i dont know how many passes it did in 30min but im think about 6h test on linkpack this night will do it
March 10, 2011 2:07:31 PM

first you cant leave on auto for vcore or vtt and hope achieve anything .... set your ram timings and ram ratios manually. Then make sure RAM voltage is what the Manufacture recommends. Then raise your VCORE and Vtt slowly until you post .... Once u get into windows run Burn test and prime 55 ... once u can past 3 hours on prime 55 your good
March 10, 2011 2:15:22 PM

i did put the v.core manually qpi cant recall maybe its on auto rams i did manually and all im missing now is a long test on linpack witch i just downloaded in a intelBurnTest file ^^ keep you guys posted and thanks for the help

That's pretty good but a bad RAM speed IMO. Try 200x19 at the same voltages, and then see if you can get the RAM stable at 1600mhz. What is the RAM's spec speed and timings?
March 10, 2011 2:21:39 PM

cheap ram`s :p  transcend jetram ddr3 1333 600MHz 8.8.8.22 TRC30 @ 1.5v on all speeds 444~666MHz but they are good so far i could push them to to 1810 on 1.5v :o  but i think i might just push them too far like that so ya 1600 might sound sexy now ^^
a c 100 K Overclocking
March 10, 2011 2:35:57 PM

Oh ok well it's not terrible. At 1.5V 1600mhz 9-9-9-27 might work. And if you're lucky @1.65V will let you run 1600mhz 8-8-8-24 although I don't know that I'd recommend that if the manufacturer doesn't.
March 10, 2011 3:33:06 PM

i tried to run it on higher speed`s but i can only do that if i want to run it on 1910 :S and i know it wont run it this high and im not welling to put more than 1.5v on them so for now its 20x190 vcore 1.280v (cpu voltage = +0.100 on bois)on cpu-z QPI=1.25v DRAM=1.5v PLL=1.8v Ram timing 9.9.9.24 on 1520 missread the last ram speed`d before atm testing it wil linpack very high =4gb ram and 10 test`s some how im getting lower temps oO high blck same vlots = lower temp im guessing my cpu can run faster on the same volts after this i might give it a try 6-10 now on linpack and im doing 65.64.62.59 on realtemp
March 10, 2011 3:36:38 PM

ooh! i cant edit anyways the rams dont have any kind of cooling system thats why i wont push them far after all remember they are cheap :p 
March 10, 2011 3:48:30 PM

ok the 10 runs was doing to very high all the results are the same temps are 65.64.62.60 im going to safe the settings and try 20pass`s on 2gb tonight but for not im going to test the 200blck make ^^wish me luck on the same vlots :p

i need to ask you some thing ! i read some were that ram volts vs qpi volts should be with in .5v like this gay says
((Make sure that vDimm - vQPI ≤ 0.5v and you should be fine.))
now i have my qpi on 1.27v and my ram on 1.5v i only count .23v def here !! is that bad ????

March 10, 2011 4:56:56 PM

Yeah that's sort of true I've heard of that rule before. But it is to be LESS than 0.5V difference. You're half that, so it's fine.
March 10, 2011 4:59:36 PM

so it should be some thing like .05 not .5 !?
March 10, 2011 5:17:35 PM

hmm i guess i get it now so i have QPI@ 1.3 i dont want to let the rams run on any thing lower than 0.8v oh higher than 1.8v is that the case ?
i know i know i can be thick headed some times but English is not my mother language
and no im not from mother Russia :p 
a c 100 K Overclocking
March 10, 2011 6:08:45 PM

The rule is DRAM voltage be less than 0.5V higher than QPI voltage. This won't really apply to you with 1.5V RAM, but for example I have some performance RAM that runs at 1.65V, so my QPI pretty much has to be higher than 1.15V, and I think at stock it's 1.08V or something...

The highest allowable DRAM voltage according to Intel is 1.65V, although I've ran up to 1.7V... I wouldn't recommend it tho.
March 10, 2011 6:16:06 PM

i dont understand why it shouldnt apply to my rams :p  i have them on 1.5v and the qpi now 1.29 im taking it down soo after i down my v.core to a more nicer place ^^
a c 100 K Overclocking
March 10, 2011 6:27:47 PM

Keep in mind Vcore and QPI are very related with stability. If you lower Vcore too much, you can't lower QPI, and vice versa. I personally like to keep Vcore around .1V-.15V higher than my QPI but that's by no means a rule.
March 11, 2011 2:14:02 PM

yes i just did the same so for now im good with my O.C 20x190 with 1.256v on the v.core in cpu-z that gave me a 69c on realtemp when linpack 4gb was runing so yes come summer and the fan speed will go up from 50% to 75% to stay on this heat i hope i wont set it @ 100% :p  other wise i will remove all this o.c xD anyways thanks alot for you help and hope i see you around for my next O.C :>

Personally i left all my voltages on auto
hyperthreading on with air cooling up to 3.1ghz off air is good to 3.4
over that i recommend water


I... have to disagree. Auto voltages are ok at low overclocks, 3.1ghz being a small one. But air cooling is fine for some pretty big overclocks. I've done 4.13ghz on air, and I've seen similar on i7s.

It maxed at about 82, but I wasn't talking about a 24/7 OC. If I was talking about a 24/7 OC I'd have said that mine is 177 base clock with turbo enabled, so 3.7ghz to 4.25ghz and max temp is 70-73C depending on the day.

Try testing with Prime95 small FFT for at least 4 hours (plenty of people recommend as much as 8, 12, even 24 hours).

If it passes that then you can try Blend tests. If it gets an error in blend but not small FFT then the issue is RAM. If adding a little voltage doesn't fix it you can also try adjusting the timings. Memtest86+, of course, is a pretty good check for RAM.
