I plan to raise the qpi v to see if I can run at a lower cpu v (1.55v used for 4.1) but I imagine my temps will stay pretty high. So, my question - if money is no object (but low noise is still desirable) - what is the best extreme cooling solution for hot i7s? Plan to use the machine 8-12 hours per day for two years then cpu can die. :D
For extreme cooling it would be a single stage but dont expect it to be low noise, maybe it can be modded to run quiter but im not that uptodate about phase change cooling. :p:
Water would be a possibility with a "monster rad" and 9 low rpm fans.
Its noticable for sure, especial in TF2. In crysis its less noticable. In Crysis it costs me ~2fps running boinc and crysis together but in TF2 its a lot more. The bad thing is that it considerably hurts the min fps, without boinc TF2 on a 32player server dont hits the 40s, with Boinc it dips down into the 20s :|...Quote:

Hornet331 - wow that's a radiator! I wonder if i can find that here in the states. What other components would be the best of the best: block, pump, ...
just get a simple 2x120 rad with a gtz, d5 and some quiet fans :)
A nice single stage would be ideal. Ask someone like Dimas what can be done.Quote:

It's amazing how hot they get compared to the last gen. That chip must be pushing 250w to worry a 120.2. A PA120.3 should be good for 425-450w with moderate fans. Quad's a safer bet. Mines on 2xPA120.3 the actual loop temp is no higher than a QX9650 same voltage/speed. Even with the EK the core temps aren't brilliant though, 15C hotter core than the QX with the same setup.Quote:

It's odd. My ambient is around 22C, my loop is lean with no 90's or 45's, I just flushed my rad, cleaned everything meticulously, and my 4.2ghz HT on load using blend is cresting at +80C. You think it could be the Zerotherm TIM that I used? It worked great on my E8600 @ 4.9ghz 1.56v but now I'm skeptical. It seems the only thing that I can pinpoint as the weak link.
For water with i7 at 4.2+, HT on and with cpu v at 1.5 to 1.55v what should be an expected steady state cpu temp at full load?
On air at 4.1 - I am at 97C!
That high of voltage, with a livable ambient (between 19C and 24C) expect 80-90C.Quote:

Right now with [200x21] vcore 1.406v set in bios, 1.376v reported with droop during blend, 1.42v VTT and 1.78v vdimm i'm @ 52-55c on cores (all else stock). I listed vdimm and VTT because they no doubt contribute to cpu temp since they're all located on the cpu now.
With same settings but bios set vcore 1.49v, reported with droop @ 1.456v, i top out at 59/60c during blend, again HT off. Will do some testing with HT eventually to see how much temps rise out of curiosity.
my new one can handle higher uncore freq. :)
max. with my D9JNL, but i think it is the uncore limit :D

1.344 - 1.360vcore, 1.375 VTT, 1.86v PLL and 1.66vdimm which is stupidly low for these clocks. I use HT on primarily because every benchmark that I've ran gets a boost from it. That's pretty much all I do with this rig; bench and game.Quote:

I know it well enough. I mean generally, they don't usually match what you can get separately or it may not be entirely suitable. And if he doesn't know what he's buying there's plenty of stock around with the old Apogee. Personally I'd look at a PA120.3 (or Feser), DDC Ultra (Petras Top) with an impingement block like the EK Supreme. I tried a high flow D-Tek, gain a few degrees with the EK. Triple rad for a little more headroom with slower fans and the DDC 3.20 to match the more restrictive blocks, but a D5/MCP655 is fine.Quote:

Reverend - yes! exactly - not a lot of folks are hitting 4.2 HT on - including me!

When I am not benching with this machine (and that is not often) I run at 4ghz HT off (21x191) @ 1.28125v, see below -
Well, you can always try to tell your place where you are buying that you want to buy a CPU but only if it has ####B### in the code, instead of ####A###. However, there have been some A chips as well that were good for voltages. As they are the same stepping I would say that there may have just been some issues with the very early chips, but I will be able to tell that soon. I am getting a brand new i7 940 from Intel in a couple of days so I am eager to compare it to the existing one. If I can shave down the voltages to 1.35-ish range for 4.0GHz I will be reasonably happy. The 1.2xV chips for 4GHz are lucky even if they are B chips.Quote:

Looks like there's more uses for Intel's Turbo mode on DFI UT X58-T3EH8 especially for single threaded benchmark/apps like Super Pi. In bios set Turbo enabled, EIST enabled, Set to 1 core enabled and you have access to fixed 22x cpu multiplier :cool:
Quick Prime95 @22x134 Bclk with DDR3-1600/3200 DRAM/Uncore frequency set in bios for 6x DRAM memory multiplier.
http://fileshosts.com/intel/DFI/DFI_...ime95_load.png
Will test more to see how far I can push cpu and Bclk with 22x multiplier :D
Also flashed from intial 12/18 official bios to 12/31 beta bios for improved DDR3 memory compatibility as well as support for latest setFSB 2.1.88 :)
More 22x cpu multiplier results:
- With 22x multiplier, seems max bclk in memtest is 208 bclk compared to 21x multiplier and 224 bclk
- With 22x multiplier, max windows bootable is well below 200 bclk, I booted into windows at 190bclk and using new setFSB 2.1.88 bumped bclk to around 200-205 for max screenshot and validation. Compared to 21x multiplier and 220bclk bootable from bios into windows.
@22x205 = 4515Mhz at 1.52v idle (vdimm = 1.875v bios)

Ok so trying to push the boundaries here a little – see below.
Trying to figure out if I can get 4.2 HT on - prime and linpack stable.
So, on air - linpack passed 5 runs but at an outrages temp of 100C about 10 times in quick hits– it is a wonder it did not blue screen or restart
I also ran prime for 5 minutes just for comparison – max temp was 90C, a full 10 degrees less!
So I don’t think this is a doable do on air but I think a good water setup might have a chance on this proc? Your thoughts?
eva2000 - do you like your 3520/SSD set up?
I have been very pleased with mine so far - see link in my sig.
Question - I was never able to figure out how to change the block size on the 3520 - what 3520 bios and driver are you using?
Mine is - HPT 3520 FW - v1.2.22.16, BIOS setting utility (driver?) is v1.3.1016
I wonder if a later bios/driver adds the ability to change block size?
I also posted a review and a comparison of raid 0 SSDs at -
http://www.ocforums.com/showthread.php?t=549980
and at -
http://www.ocforums.com/showthread.php?t=552010
EDIT - I see it - "Before plugging in the OCZ core SSDs, I flashed the 3520LF controller to latest bios and firmware versions, 1.40.0416 and 1.3.28.16 respectively." But did this allow you to change the array block size?
block size is changed from within 3520LF bios on boot up and so yup i could change it see screenshots http://i4memory.com/f9/ocz-core-ssd-...744/#post98279 it's a linked not inline image.Quote:

What block size are you using now?

I'm not sure if you can trust that or not, i passed 50 runs yesterday on linX (2hr 50min~) then proceeded to crash after 9hr of blend. I know it's 3hr vs 9hr but from what pretty much everyone says 10 mins of linpack is supposed to be more reliable than 10 hours of blend. I don't know why but i had a feeling this would happen, i'll probably be sticking with prime after all.Quote:

Its only the long term cpu volts that I'd like to know opinions on.
ranger07 - What are your multi's at?
rge helped me find a little trick that you might want to try.
At least for my 965, I found that running high bclock and low multi gave me much lower temp then the other way around - see below -
I agree - I doubt my 4.2/HT on would last an hour on prime.Quote:

.. If your using high speed fans go for high-fin count radiators.

How much vcore are you using? 1.385v? what kind of cooling are you on?

1.35v and 78c max prime load are nowhere near the worry zones, it will probably out live you ;)
Good to know, thats a relief. Are there other voltages you can drop to help lower temps? Such as RAM, PLL, etc etc?
When you guys post your OC can you guys state which bios your using?
so many different bioses for a lot of the boards.
I'm on the newest P6T bios whichever that is... just flashed it about a week ago.
Anyway, do you guys know which voltages you can drop besides CPU voltage to effect overall heat? Does dropping the DRAM, PLL, QPI (and others) effect temps?
They're all voltages that are going into the cpu itself so they will affect it to some degree, which voltages will make a difference to your cores though (the temps you care about) are up for question.
You should try to run with lowest volts possible anyway, on all settings :)
Looks like I have some detective work to do then. I'll post in if I find anything interesting. And anyone else with info please chime in.
Have a look where prime crashes on blend... mine kept crashing on 4096 FFTs, however, ran 24/7 with small FFTs only. Therefore, I concluded that it was down to memory timings/voltage and not the CPU. So I raised the Vdimm a little and slackened off my RAM timings... it still crashed?? So... I lowered the BCLK from 200 to 190, now it's stable @ 4.0GHz (21x190) and it could only do 3.8 before. :) Yea I know it's still 3.8GHz for multi-threaded apps, however, I have an "A" revision chip and I'm happy with 3.8GHz stable for 24/7 use.Quote:
Originally Posted by Xello

Good point, i might look into that later. I wonder if you can set 5000k+ FFT's, to use up the same amount of memory linpack does.Quote:

Thx
my 4.0 on air - this is also a doable do with cpu v at 1.4v, qpi at 1.34v and dram at 1.64v
So, my i7 920 will be here on Monday or Tuesday. I will be initially running on air using a Noctua NH-U12P SE1366 on the bench while I decide on what case I want to put this new build in. I was going to order a TRUE but was having a hard time finding a vendor who had the 1366 bracket in stock. I will be going water with a dedicated CPU loop ultimately. Anyway, in my tool box, I have both AS5 and Ceramique. Any idea which one I should try first with the 920? I suppose I could try both, just trying to see if anyone has already been down this road. Thanks.
AS5 unless you are going sub zero
Interesting, I'm not sure my CPU would be stable at those settings though (its picky) but the 30x/134 setting is very interesting. What made you come to this setting... is it more stable than having a lower multi and higher BCLK?Quote:

The 965 lets you get past that, but there are SO many 200x21s it seems that is the Q6600 G0 equivalent of 3.6GHz. The question is what is the limit in the 4.4-4.6GHz range? Is it QPI, which means that the 940 may show an edge of the 920? Or is it the CPU itself, which would mean the 920, 940, and 965 are functionally equivalent?
So would you suggest that those of us who have troublw at 20x/200 try something more along the lines of what SteveRo did, with a 30x/134? Is there any danger in using unbalanced combos such as that? Or is it in fact more dangerous to drive the BCLK up (like 200+)?
If you have a 965 you can try everything independently and use the Bclk for granularity between multipliers. If you can't get a 200 Bclk I would think that tuning that independently would be the first step. The QPI is 3.6GHz which is fairly close to the stock 3.2Ghz 965 setting. Can you make 15x200? It should be similar to any other system. I tried, so far unsuccessfully, to get posts of Core i7 settings in a different thread. Otherwise, they are spread all over.
Have you seen the NCIX video or read Saaya's thread?
Yes, I've seen the video. I was simply wondering about the merits of high multiplyer with low BCLK vs those of low multiplyer with high BCLK.
By the way, I believe I have reached a Prime stable 3.8ghz overclock. It just passed through 4 hours of torture testing with all 8 threads, with a top max of 77c and an average max of 75c.
It is as follows:

Here is my daily setup for now, still going higher day by day:
Got a shot of my background so you'll can see what the rig looks like as well :D
quick run in wprime so you can have an idea of what temps are like, dont get any hotter over the hours

I have found (so far) - for HT on - I have better success with high multi, low bclock. Just the reverse for HT off - lower v's and temps come with low multi and high bclock -Quote:

i ran at 4.2 GHz stable for about one week until I decided to re overclock the whole thing, i have it saved in my bios though, I can just go and load it, works like a charm. HT Enabled of course, if you want some benches let me know, I can post them :DQuote:
