[Socket 754] MULTI-record (SuperPI - Pifast - Screen)

Today we did a Dry-ice run with a Socket 754 3700+ clawhammer which allready did 3137pifast on a prommy Mach1 @ R507 :).

The hardware used:

-DFI Lanparty UT NF3 250
-OCZ DDR booster
-OCZ 256MB and Mushkin 256MB (OLD bH-5)
-PCPower&Cooling 510w sli psu

And last but not least the 3700+ clawhammer S754

And some pics:

The Home made container and holddown mounted on the board

Checking the contact. It's ok :). Insulation ring greased up with vaseline to creat an airtight seal. This worked great. We did a 4hour run without any condensation problems!!

Neoprene on the board (greased up).

Springs were VERY tight :D. The extra plate on the backside made the total assembly stiffer so the boards doesn't bend under the extreme stress.

3.9v on the mem. 4.0v has been used allso but didn't help.

Container on a artificial load (movie will be online soon!!)

Tnx to The Doctor who polished the container and helped me on the run :)

Nice setup. My dry ice tube doesn't hold load at all :( Have any pics of the inside?

For the container

it's just a tube on a round plate with ring for the holddown. That's it :)

very nice craftsmanship on that. and GJ on the world record. 754 for life ;)

wow, most impressive. :toast:

Well done, guys :toast: Great container and setup!

Also, not only CPU clocks, but BH-5 is running really nice :thumbsup:

awesome

i see a dt200 AND a fluke 52 :eek:

Fluke 51 ;)
The fluke is mine the dt200 is epsilon's

wow, nice scores. I think that is the wr, but I'm not sure.

Dang guys, very fine work :toast: I for one can appreciate how hard that must have been, since I was playing with DryIce+3700+DFI-nF3 yesterday too :D though sadly I couldn't get as high. What stepping/week is your 3700+? What core voltage? IHS on/off? Loaded temps?

Sorry for so many questions, hehe, but I am very intersted in your answer :yepp:

Well done fellas :clap:

KICK ASS!!

sry, but that rocks.

I dunno though, that's a lot of volts running throught that chip.

Very good :D

We made a movie of the superpi 1M run. You can clearly see the temps rise :).

IHS was still on.

This is the stepping:

What were your resultst ? :)

Very nice job guys. Lots of s754 action this weekend :D

Great job, who would have guessed S754 being that fast... on the other hand, dual channel doesn't give you that much.

Nice WR

Hehe, funny watching those temps rise and rise :D :eek: The video stopped at -55C, did temps continue rising after that?
And what was core voltage for those speeds?

Your stepping is VERY close to mine (CAAZC 0441DPMW). I don't know what my temps were since I have no temp-probe, and I don't trust BIOS --- actually I don't WANT to believe the BIOS :p: :( It said my temps were -38C to -43C at stock volts, -28C to -33C at 1.9v+ :eek: :mad: I'm really hoping that's not reading correctly.

My max 3D was 3207mhz with 1.92v, I ran a Super Pi at 3240mhz with 1.92-1.95v, but crap mem speed so not good score. Suicide screeny at 3331mhz. My mem is not very good, I can't seem to go above 270mhz at all :( and I get boot problems at high vdimm (3.6-3.7v). Most times the board just won't boot up even though fans come on, no video display.

-55c was the end of the run after that the temps went down pretty quick.
Epsilons board didnt boot at 3.6+ vdimm either just boot and turn the vdimm up right after the boot.

Good work there guys. Clean setup and impressive results ;)

:toast:

so cold ice iss just ice cubes from the frig?

:rofl:

solid carbon dioxide, aka dry ice
the stuff is usually around -78c, or colder

So adjust PSU 3.3 rail after powering on? Isn't that risky?

Well we used a OCZ DDR Booster

But adjusting the 3.3 rail is ok though. The PSU most likely is protected. My enermax 465w stops at 3.75v at the 3.3v line. Above that value, it just shuts off. I didn't wanted to mod my PCP&C PSU because it is new and expensive :D. So I bought a DDR Booster.

If you raise the voltage slow it will not matter. The board can handle it. Within a second The Doctor (accidently) lowered the voltage of the DDR booster by 0.5v (single turn pot isn't a good idea, they should definately take that into reconsideration). The system crashed but everything lived. So if you use a multiturn pot on the Vsense line of your PSU, you can not kill anything unless you use an electrical screwdriver to turn the pot ^_^

Of course its safe! Just go slowly.

Very impressive clocks guys, congrads! :toast:

nice work

congrats :D

its close to if no the WR for 754, and beats the clawhammer WR set by eshbach and myself a few weeks back.

congrats guys! :clap:

Fantastic results! :toast:

Tnx Haldol

Now it's up to you :)

Nice job m8s

I need a new cpu :)

Nice Job! I wonder what you could do with Newark. :D

yes.. i want someone to lend me a phase unit soooo bad :p:

LOL It would be cool if you could do it. HAHA you were the first with Newark! :D

I am afraid this 754 WR won't stand for long. BUT amazing that this was done with a claw. :cool:

nice work!

but I don't understand why everybody is complaining about loaded temperature rising with DI. Just use some liquid that doesn't freeze and small bits of DI and you should be fine...

congrats buddy :toast:
if its a wr lemme know and i will post it on the front page :)

Just done a search on a couple of oc-db's and i could not find anyting higher than our score so im pretty sure its the wr :D
But if anyone knows higher scores/screens please post them.

I know zxy(or is it xzy?) had 3.4ghz on a newcastle but I'm not sure how much over 3.4ghz.

Smokin:D

Very clean setup you guys have and nice results.

Very nice job :toast:

Very nice guys! I hope you are gonna try for even higher. :) lol

I've used a metal screw driver while turning the pot on my fortron 530w when it was on(couldn't get a wooden one). Was the scariest thing I have ever done... :yepp: :shock2:

lol :D

You got a very nice score there zyx :D

Nice scores man :toast:
Too bad our cpuz files were corrupted. We had a file at ~3460MHz but when uploading the site gave an error (file corrupted).

WOW rocks :p:
