8 Packs 4ghz 32m Challenge win full Haswell 4770K Bundle.

Although it's just over 1GHz down on the other cpus, it's surprising just how close this is to the performance of current amd tech.

I've got an old Duron 750 that clocks at 1Ghz sat in the orriginal Ocuk Tornado case out in the shed :) I'm tempted to fire that up and SP it :)
 
Down to 16m57s on the OCZ ram after playing with a few things.

From a little research tRCD makes a huge impact on AM3 and this ram refuses to boot with it any lower than the default 9.

Going to make a few calls tomorrow to see if I can get hold of some dry ice locally at the right price.

If I can it's out with the tin foil, vaseline and kitchen roll and this OCZ is getting the sub zero treatment until my Mushkin arrives.

Sounds like the start to a really bad porno :D Your user name doesn't help either...

I wish you luck in your experiments with 'cold'. I'm rooting for you! I'd like to try clocking with lN2 or sCO2 one day - it looks like fun.




Sorry I didn't post a time yesterday... I screwed up my custom stripping of XP, and ran out of time. Not really been saving screenshots yet because I'm still figuring out the limits of the RAM.

XP does seem a little better than Win 7 though, mostly because it lets you get closer to the limits of the RAM. Well, at least with my crappy UD4H board anyway... In XP I actually see pi fail on occasion now. On Win 7 booting in was always the real test, and if it got into windows then I knew that pi would complete. XP allows you to push a little further.

Final weekend of the competition I'll get serious about clocking what I have. For now, I have only an old laptop. Might do a pi run for giggles though...

You're right that does sound very very bad.

Duff-Man will trust you some helpful info in a moment.

If the Dry Ice benching works with the RAM I might grab some proper insulation and put the CPU under as well to get the CPU-NB higher as I have some materials and a lathe I could make a makeshift pot with.

Really. Mines the complete opposites. All my fastest times have come in Windows 7 and I'm seeing PI errors when it doesn't complete. Not sure whether it's because I'm only on SP2 on XP but I just can get close to Windows 7 times. What kind of times are you getting on XP?

Glad I wasn't the only one that came to that conclusion when I read it.

Also ManLove be great to hear how the dry ice goes. Depending on your result might have a schedule a trip to Tesco's to pick some up and give it a go.

Kei thanks so much for your help with the leaderboard. I have been so busy recently with Taiwan and Haswell launch plus several other projects.

Here is my new best:

 
Damn, good job the comp isn't to beat your score then isn't it.

Still tweaking away shaved off just under a second now at 7:5301 on last few runs but trying to break the 7:52 barrier before I screen anything.
 
They certainly seem to be from my research. 2133mhz cl9. There was a cl7 version of the same kit, doesn't seem to be available any more though.

Yes they are the GSKILL BBSE IC kit. Ripjaws.

There is more in this run a couple of settings can tweak further on the next run. TRP I think can be 6 and TRFC can be 60 for starters with more volts.

Have you tweaked the XP for Pi efficiency. Windows 7 has Large system cache enabled by default XP does not. LSC is your friend!!!;)
 
If your insulation is good probably not. Its all about keeping moisture out.

I have used tin foil several times with LN2 and its been fine. Aany problems with stability you just stop dry out and go again. Not all sticks like extreme cold though. You need temp probes attached to the sticks so as to monitor any cold bugging.
 
8 Pack what are your thoughts on the "Copy Waza" technique? - I tried the CDT technique from xtremesystems last night but not sure if I followed the instructions correctly but I could see the System Cache and Available Memory figures changing.
 
Thanks. It'll be Mushkin Radioactive 1600mhz CAS6 I'll be using which uses PSC chips which I'm lead to believe love the cold?

I'm having a few issues at the moment with them though. XMP profile for them is 6-8-6-24 @ 1.65v but they won't even boot at those timings with 1.75v at the moment.
 
Okay thanks, will see if I can get hold of some dry ice to have a go.

Just trying to figure why it won't go as tight as it should. Frequencies can definitely be pushed more than my previous ocz though.

Only testing with 1M at the moment but it's stable @ 1800mhz with 9-9-9-24
