Does that mean you posted something and changed your mind or are you putting me on your ignore list? :p

Once I've had breakfast and got the hangover under control, I'll be making a start on the watercooling for the gaming rig so that it's ready for when the barbs arrive. Once it's all together, I'll get the loop tested and see what's what. I have to work out how to fix the rad onto the case as I don't have any screws short enough that fit - may have to resort to cable ties for the time being.
 
Looking good Stan, I think you might be able to fold on that keyboard as well :D

Alcohol + PC building is all good, nothing like sitting down for an evening with some new boxes and a few beers! :p Damn it now I'm being drawn to the buy now button!!

Ooh, shiny! Even though I don't fold, I read the news that SS does - so I'll no doubt be seeing your name planted firmly at the top of the table now :cool:

Build was relatively easy - overclocking was a challenge. These i7s are a lot trickier to OC than the old chips but so rewarding. She's currently stable at 4.2GHz on air :cool: RAM is running under speed but I'll tinker with that later. CPU temperature is close to 80 degrees at full load which is absolutely fine.

nice! my i7 is in an SG01- not enough room to cool. Dunno if coretemp works on linux, but do you know what the tdp is? i found that i could clock to 200 x 21, but the tdp was 147W or thereabouts- higher than the chip rated at, and way higher than what the small cooler i had could handle.
way too hot though, it's now at 180 x 18 to be at about 85 degrees on air under my bed (who needs the heating on at night).
 
Ignore the TDP stated by Core Temp. Is 180x18 really the best o/c? Surely x20 (or x21) would yield similar results for the same temperature (by lowering the BCLK) but reducing chipset heat?
The standard TDP is 130W but you can work out the actual wattage here according to your overclock. Assuming it's accurate (and it should be, since it's tailored to your CPU type), my 4.1GHz o/c with a 0.1ish voltage bump's at over 200W.

4.2GHz, nice OC. What settings did you use?

Also, what is the general method for OCing an i7? There are like a million things to tweak by the looks of it. My C2Q was as easy as pie in comparison o.o
 
My method:
  1. At stock, check load temperatures just in case the heatsink needs reseating or something
  2. Change most if not all settings to manual (I tend to ignore RAM timings and suchlike :o). Made easier on the UD7 as it tells you what the default values are, whereas my P45 Asus did not.
  3. Decrease CPU, RAM and uncore multiplier (uncore multiplier should be at least twice RAM multiplier) while increasing BCLK speeds - this is an attempt to find highest stable BCLK for your mobo, just keep all other components at stock or less.
  4. Increase the other multipliers in turn to give you a feel of what they're stable at. Tweak voltages as desired. RAM I keep at/under 1.65V; uncore at/under 1.35V and when I have sufficient cooling, CPU probably under 1.5V.
  5. CPU max temp is 100°C before throttling occurs; the amount of safety margin you want to give is up to you. Mine is always between 75-85°C when folding.
  6. Stress testing etc is just the same as when overclocking any other CPU.

More detailed/better information will be found in the Overclocking forums :p

Edit: Oh, and there's a few features you may wish to disable, like speedstep IIRC, can't remember all of them, but leave hyperthreading on unless you're a clock speed junkie and only want 4 threads :p

It was actually Penderyn. I had it a few years ago at the OcUK Christmas meet in Swansea and proclaimed it (loudly in the middle of the pub) to be ****e. I felt I may have been a little harsh so I bought a bottle from Tesco the other day to give it a proper try. I have since upgraded it from ****e to unpleasant. Only reason I was drinking it last night was because it was all I had and I don't do overclocking without whisky :D

To be honest, I can't remember. I'll have a look later as I may have to tinker with it a bit more as it's frozen on me a couple of times today. It ran perfectly fine overnight for about 10 hours but has frozen twice since I moved it through to the other room :( Will see how it goes - if it freezes again I may have to ease it back a bit.

On another sad note, got my watercooling all set up and switched on to test. All the fittings seem to be perfectly fine but the waterblock is leaking like a sieve. Currently waiting for a reply to my RMA request.
 
Thanks for the info guys. Looks like I may be building my new rig later on today, or at least making a start.


And that sucks about the waterblock. But Stan, you work on an oil rig! Weld it back up yourself, man! :p

not to hijack stan's thread, but if i run 170x20 or 21, my temps stabilise at about 95-100 degrees (the multipliers drop when it hits that obviously). I am running at a very low voltage, I think at 1.08V or something close. Will have to play with the wattage tool later :) The multiplier seems to have a greater affect with regards to heat generated compared with the BCLK increase in my system, which is why I went to 180x 18.... was toying with 200 x 16 too, but i think then the BCLK starts playing an effect to the reported temps- so I settled on what I thought was my temp sweet spot :)

edit: I know this chip can do much better, but its just the case size and cooling solution that I have on :) If i leave the box cover off and blow a 80mm noctua at it, the temps drop another 10 degrees, so....
 
Never mind deltas, get some of these puppies in it:

:D

Seriously though Grimgoth, get yourself a better case and cooling (either that or keep it naked like I have :D). You're strangling the potential of that chip.

Sirius B.
Had a quick look last night as I had to tinker after it locked up again. The settings I can remember are that it's running at 200x20 with turbo boost switched on giving me 200x21 Vcore is now at 1.4V (nudged it up from 1.375 last night and it seems to have stabilised it) and uncore at 1.315V. Ram is underclocked atm with a x6 multiplier taking it to 1200MHz with timings of 9-9-9-20 and on 1.66V (might try tinkering with that but it's working fine for now). I did nudge up a couple of other voltages but I forget which ones - not sure what difference they made (if any) but I read them somewhere on the web.

As reported above, lifting the Vcore to 1.4V appears to have stabilised it. It's now run about 10 hours uninterrupted. HFM is reporting a TPF of 29.23 and ppd of over 29,000. Total ppd for the farm, according to HFM, is 54,589 and that's with the gaming rig still out of action. With that up and running on SMP2, I should easily get over 70,000 and when it's on bigadv when I go to work in a month or so, it should be around 80,000 :cool:

Better buy some more gfx cards KE1HA :p
 
Never mind those fans. Spacesuit fans (ex. NASA) are where its at. 19,200 RPM. I hear (!) there might be one going spare soon - it only does 18,900 RPM. I doubt it will come with ear protection though (sound doesn't travel in space). :p

Nice job sir. I wish I had the skill and/or confidence to watercool and overclock to those levels.
