^^^ so basically lower multi, higher BCLK will provide lower temps as you can lower your QPI/VTT voltage and more stability? I use a excel sheet sometimes to do gather some data together, helps out a million :)

I have the NBMAX on the Northbridge. Was also thinking about getting the EK MOSFET blocks and the EK NB/SB full waterblock. Going to hold off on that until after the holidays. Hoping someone else gets them and I can see if there are any performance gains.
I am just cooling the CPU. NB stays relatively cool on my board, it has a little fan on it from the factory.
I might try the little ASUS sidefan that came with the P6T aimed at the NB or DRAM .. has anyone used this thing on the MB at all ??Quote:

Gone retry tonight to see if it wasnt a fluke .. but I might be happy enough with this for everyday gaming use (which is all I care about in long run) - played Crysis & Assassins both over an hour with these settings no problems at all ..
Also primed for over an hour (stopped manually) @ 1.45V CPU .. but with crazy temps ..
I think I got to about 40 minutes before it failed at 200x20. But I've run over 14 hours at 211x19 with 1.36vcore.Quote:

The rest is the same as yours. There's something obvious that I might be missing but I'm happy with 4.0Ghz @1.36v for now.
I figured out why I couldn't post at a multi of 196, I forgot to disable turbo mode, so 210x21 equals 4.4 GHz which at 1.35v I dont think will boot. Imma try it again and disable turbo mode to get 4.0 GHz then try to work my way up to 4.2GHZ at x19
What is your QPI/Vtt Volts and other settings for this screen ?Quote:

I'll give it another shot when I get home, but I have no clue how you guys are doing this with 1.39
Well my head is officially done in ..
No sooner had I achived my own Prime Personal Best (over 2 hours and still running) with flashys settings from above there.. now when I try go back to those settings.. I can barely even get more than 1 Cinebench run .. sometimes cant even get into Windows !
I think I've given up .. I've gone back to basics .. set 200x20 .. the rest Auto .. it seems to run multiple loops of Cinebench and all my games .. thats good enuf for me ..
I have an Asus Rampage II Extreme. With the stock fan I can get my i920 to a Bclock of 160MHz. I raised the CPU voltage to 1.4V but this did not really help.
I have a Mach II GT cooler which cools the CPU down to -50C. Under a 200W load it goes up to about -10C. The thing is that colling the CPU did not change the Bclock performance. I was still only able to get a Bclock of 160MHz at -50C. Once I had the CPU at -50C I also raised all of the CPU voltages to their maximum safe settings (core voltage at 1.5V) but this did not help.
I am assuming that it is not the CPU that is holding me back. I reduced the memory speed so as not to exceed the rated speed of my memory so that is not the issue. Can anyone give me any pointers?
Man stop doing that it makes me wince :eek: :p:Quote:

OK, my system is up and running (P6T with 920).
Must read a little bit about Nehalem Overclocking (coming from S775), but don't have the time before christmas holidays begin.
So would you guys be so kind to give me a little starting help ?
Some good starting settings and more important values not to exceed (like QPI voltage or the well known dram voltage of 1,65v) would be awesome ;)
got me a L383B107 Batch, maybe someone has tested one already and knows how it clocks ?
lol 1.75V qpi... talk about stressing the chip. :p:
Ok, I'll try 1.4 Qpi/Vtt and if that doesn't work, I'll come back and post my system specs as well as bios settings. Hopefully, someone out there will be able to tell me where I've gone wrong.Quote:

Try 200 x 20 and with 1.4 vcc and test for stability.
Yeah i wouldn't go over 1.5v while testing max qpi / bclk etc. One reason is because that's a sort of limit i set myself based on what i've seen and another is that i already know i can get up to 216bclk with 1.44v stable, and that i won't be wanting to go that high on my final OC anyway.Quote:

So there's no way i'm going to set a whole .08v higher for only 100mhz extra when the clock is already so high that it won't make a difference to me personally.
Please do post your bios settings though, can't figure out why you need such ridiculous VTT. When i started to find max bclk all i did was:
Bclock 200 (my starting point as i knew it was stable already)
CPU Multiplier 12x
Uncore Multiplier 12x
QPI Multiplier 18x (36x in bios)
Memory Multiplier 6x
Vcore 1.275v
VTT 1.46v
Vdimm 1.64v
Then i started raising bclk until i hit walls. Under this setting your roof is only going to be how high your QPI clock tops out - meant to be around or just under 4ghz.
I'll give this a shot as well. Iirc I did try it when I first got the chip and I couldn't go over 200 Bclk with 1.46vtt. I then raised it to 1.55 and was able to hit 205.Quote:

Not sure, maybe someone else running the same can comment. I wouldn't think it would need a whole lot more juice. Maybe at higher (1600mhz?) clocks, but for now try reducing memory multi to remove that bottleneck and see what bclk / QPI / Uncore you can get :up:Quote:

He he, I hear ya. I've been begging for a step by step for a while. I guess if nobody else makes one I'll go ahead and document and photograph my entire experience when I OC here in a few days. Only problem is that its my 1st OC, so I'm not so sure how professional of a source I'll be. ;) I've been trying to do my homework though. From what I can tell it involves lossening everything up (to maybe 12) and then seeing how high you can safely get youe bclock... then you keep that and start tightening the next component. Does that sound right guys?Quote:

Then I can take it outside in 5C air, UC 14, mem 6x, Vtt 1.68, +/- DRAM 1.8+, and +/- red line all other volts, bclk will then go to 217 barely load windows then freeze. no higher regardless of settings.

your bclk seems to go from 205 to 211 like mine goes from 215 to 217. I think both are just near their limits.
Yep. I can run 200 Bclk on <1.4 Qpi/vtt, but for me to run 205, I need about 1.55-1.65. I can't remember off the top of my head, but somewhere within that range. You saw what it took to get 211 so for me, I'll have to settle with 200 x 21 for now.Quote:

Sounds like you're limited by your chip after all then lukee. What's with all those other settings though, cpu pll etc? I've hit pretty high clocks without having to touch that stuff (not even sure what it does), i wonder if they're high enough to cause instability.
I agree if you want to 'challenge' someone to a benchmark create a thread for it. Alternatively, there are probably a hundred reviews by now detailing how much faster i7 is than penryn at any given task..
4.3 prime stable 10 hours - HT off, unlikely I will get 4.4 on air but must try!
The spread sheet was rge's design - good approach!
I think 4.3 on air is the max for me - 4.32 @ 1.55v is way to hot!
Interesting that it actually got through linpack x5.
On real temp - when it reaches 100C - thermal status goes to "HOT" for that proc.

Bring memory Multi to 6x and Uncore Mult to 15x. That should give you more stability.Quote:

rge - did I get that right?
That was dejanh with the uncore to qpi ratio of 8:9 on i920's. uncore to memory is 2:1 or higher.
Yeah, i should have said before all other voltages on auto. There's a post on this thread from way back with someone who was using all sorts of voltage increases, cpu pll / qpi pll, IOH core increases, etc and some others from that page of the bios. I tried out his setting with all those tweaks and while it was stable, i then tried it with all of those on auto (just keeping the vcore, vtt, and dram), and it was also stable!Quote:

If they allowed you to set your own multis, from 12 to 50 or whatever, everyone would be happier.
Is there a reason they only have for example 3 to choose from on QPI, does anyone know?
965 = everything unlocked.
And expensive... ;)
word, and they're grossly overpriced unless there are intentions of using DICE/LN2. All I've seen with the 965's are high assed multi's and weak bclk's. the guys who are taking 920's passed 4ghs are in the win this round.Quote:

Still, cheap as chips compared to the QX9770!
Just because your temps are under control does not mean you will be able to get higher clocks. After a certain point more voltage to your components will not gain you anything in OC ability. I cap out at 4.2GHz on air (good for bench, not for 24/7).Quote:

reverandmaynrad: I have the 965 and so far several folks with 920s and 940s are doing better than I am.
QPI options for me on ggbt extreme mobo are: auto, slow, 36, 44 and 48.
Is this the same for the folks with 920 and 940s?
QPI needs to be much more adjustable - like uncore - x12 to x48.
My I7(RMA) is going to be shipped out tomorrow, I hope that I get I7 B' batch, as it seems to run on low Voltage as per the members in this thread.

got the same case as me, looks good, here is a few shots of mine:

I can no longer justify spending all my free time rebooting my freaking computer!
One thing that I am considering is just buying a SS. I hate throwing *more* money at a problem, but, at this point, anything to avoid the BSoD.
So those multis aren't unlocked on the 965, that's what i thought.Quote:

Depends on what CPU and on much youve OC'd, 4.2 is def not the max for a 965. Prob 4.5- 4.6Quote:

What are you talking about? It's all chip to chip. There is absolutely no rule of 965 clocking as high as 4.5-4.6. Infact, there is barely any that are clocked so high.Quote:

I agree. I don't know what kind of binning Intel are doing with these chips, if any, because so far we've seen plenty of 920 and 940s going to insane clocks just like some 965's are, under xtreme cooling, obviously the 965 is just a more efficient option if you are doing that because of the unlocked multi.Quote:

I'm really impressed with i7 and x58 in general in this regard, the bios's have been coming hard and fast and pretty much every board has a feeling of maturity about it even after such a short time. It's easy to complain when things go wrong but it should be noted when things go so right :up:
yep i admit im happy with my 920 , 4ghz - 4.2ghz stable with HT on is good, but i do feel sorry for the ppl that spent more on 940's and 965's and are almost getting the same clocks , ok maybe 4.3 - 4.4 prime stable* if there lucky, if the 920 goes to 4.2ghz prime stable then the 940 should go to at least 4.6ghz prime stable and the 965 at least 5ghz prime stable, but thats just my opinion :D
Do we pay much of a performance penalty by setting qpi to slow (gigabyte boards).
It looks like this is the setting I must use for qpi - if I want to use high bclocks with HT tuned on.
I think qpi on slow is something like - 100xbclock, so for 200 bclock that would give a qpi speed of 2000 vs stock speed (for 965) of 3239 mhz.
QPI only makes a marginal difference, and then only even only for multigpu setups.Quote:

I dropped the voltage down to 1.4v in bios but in windows its still running at 1.475. Going to knock it back to to 1.35v in bios and see if i stay stable.
I game. When I've been able to have a system run stable for 2 hours on Prime, I don't have any issues gaming. My PC isn't on all day, I just use it for 2-4 hours Max.Quote:

I say reasonable because these things run scorching hot out of the box so, you get my point.Quote:

Cooling is not an issue because my max temps @4.0 range from 69-73C across all four cores with HT enabled.
Yes, I was lazy and put a Koolance Exos-2 LX with an Apogee GTZ water block on it but my CPU is the only thing in the loop and it seems to be working very well. Plus, I must admit, if you heat this stuff in hot water and then apply it correctly, I think it's paid off royally:

My temps are consistent with the most "hardcore" H20 rigs and I think it's because I used the best water block and TIM, not to mention that my CPU is the only thing being cooled.
Do you mean 10 hr small fft + 10 hour blend, or 20 hour small fft + 20 hour blend? You shouldn't waste your time with small fft, it's for testing max heat output - good for testing your cooling. It puts less stress on the cpu than large fft, which is why Blend is the best option :up:Quote:

i have a 965xe. Am i right in saying _ALL_ i need to do to overclock this is just increase the multiplier (along with Vdim) and not worry about the QPI? I am currently running at 4ghz stable with:
BLK: 133Mhz
Multiplier: 30x
Core voltage: 1.275
My QPI is currently 3.2GHz.
I use everest, but for some reason it does not show my real cpu speed or multiplier, for that i have to use cpu-z, any dieas ? is everest not compatible with i7 ?
