Ok folks here is my OC score 4,44 gigs, just be water cooling the cpu only

a D0 stepping core i7 920 PRIME 95 stable showing SUper pi score.

Nice clock :)

What stepping cpu is that?

not sure mate

cannot find box anymore, tell u what ill pm you next time i do a re-build/review which will proberbly be in a few days time:P:P:P

hahah

No worries, I already have a D0 but i'm just curious to know which batches are doing well :)

Obviously the big thing about this is temperatures...and you seem to have missed them out :(

Indeedy, would be interesting to see what they are like after a while under full load.

gilgamesh
22-01-10, 21:29
with 3 low cfm noctuas

59c-60c on hottest core after 3 hours of prime95 full load, ambient air temps 21c

would anyone like the full rad air in/ rad air out, fluid in and fluid out temps?

Nice :D Is it IBT / LinX stable mate ?

I can (at the mo) get it at just over 4.5 and do a few benches, but defo not what id call stable :P

That's a very nice clock, the voltage isn't bad either.
Temps and a stable shot would be awesome :)

gilgamesh
23-01-10, 12:51
think i can do that 4.5 it is possible

220 on water seems tgo be the last stable setting. Think i can get higher by LOWERING the CPU BASE clock on the DFI X5U8 UT. I should hope so anyway as the cooling system on that board is loosely based off the dfi x48 t2rs which i helped to design with feeeeeeeeeeeeeeeeeeeedback

ill speak to jimmy su FAE at dfi to see if i can get higher on water. If not its back to my D-ICE POT:(

23-01-10, 15:22
Nice. :)

I could probably push 4.2ghz from my i5 but temps will be hitting 80C + under prime so I'm not bothering.

Max stable base clock I can hit on water is 235 on an 18 multi. I can boot into windows on a 20 (4.7ghz) to cpu-z but thats all its good for. I get the BSOD running super pi 1m lol :D

Knocking things to a 21 multi see me with a bclk of 224 but thats with 1.43v and temps in the low 80s.

Its good for a vantage run which nets about 26k I think (57.5k with physx) so its all good.

i have a q6600 and hyperpi takes 32s for 1m !!
v v v nice!

thats a little slow ;)

my Q6600 did it in under 14s and it's not the quickest!

295s are epic mate! Faster than your 5870 by a chunk but slower by just as much when compared to the 5970. They overclock nicely, don't get too hot and run games a treat. I don't think there's a game out there that can't be played on max settings with AA at 1920x1200 which makes it a very attractive card indeed. If you look hard enough they are dotted about but your looking at £400+ which is a bit of a shame.

as you know i have the bfg one

best way to describe it is

the core clock speed of 2xgtx260's in sli
but the RAW shader power of 2x 280's

MATE THOUGH THEY do get hot REALLY HOT BUDDY
hence why im looking at wc-ing mine

but they are fab cards m8

I'm fortunate with having the single pcb cards that hit about 65c underload when overclocked so it's not too much of a problem. The dual pcb ones get a bit toasty though I must say! My only gripe was the cost of the blocks!! Nice description there btw ;)

strange as my bfg one is a single PCB version, and its hot in idle buddy . hotter still to the touch on full load=ouch

Really??

Im sat looking at idle temps now. Got them back on air as i need to strip the blocks back and give them a clean inside. Seem to have a bit of a sludge issue...

Anyway temps are in windows 39/40/38/40 for the cores, 37/40/37/39 for the PCBs. Thats with fans on auto sat at 40%...

Fans still on auto when gaming and cores never peak past 65c. PCBs a little cooler.

sludge in your blocks, your not using feser are you???? grrrr

use thermochill or plain deionised-distiled water

It was feser yes.. Nasty stuff! Ive got a couple of litres of distilled water to go in.. I use black hosing so its not as if I can see the liquid in the pipes...

do me favour andy

can you report that issue on my site and inc photos please? I know what the main issue is with feser

I am collecting evidence from people with that issue, anyone else withthe same issue re: feser and gunge please report it on my site/ with photos if you can ; under the cooling section.

cheers

Its a bit late now bud.. everything has been cleaned up! It wasnt brilliant stuff, felt slightly fury but at the same time slightly jelly like. Almost as f there was algae in the coolant. Almost killed my graphics cards and CPU the stuff did. I couldnt work out why temps were slowly creeping up. It got to a point where It was cooler to run everything on air so I did. CPU is back on water now as its a nice and simple loop. The GPUs wont be until the weekend.

It does it in as little as a month mate! Right rubbish stuff! I suggest distilled water with loop dye.

AndyThe exact same thing is going to happen when you add a dye to water and apply heat...

Distilled water and coloured tubing or nothing

The loop had been up and running only a few months - noticed rising temps and drained the loop to flush and replace the fluid - After seeing the above and some Tommy L and wire brushing I went for un coloured / un readctive pure with a silver kill coil

Very strange, i bought quite a few bottles when i took a trip to tom's and i've never had a problem with it. That was last year and this is my 3rd loop since :confused:

Luckily this is my last bottle :)

What kind of clocks are max for i7's under "normal cooling" by normal cooling i mean non vapo etc or tec etc I dont have mine any more but i managed 4.2ghz 3d stable using a h50 and a asus gene II , i didnt actually try any higher which may sound odd......

As yet ive not tried clocking my i5.........

Nice overclock gilgamesh :thumb:

Wish I had a good 920 I need 1.28V for 4Ghz and 1.36V for 4.2Ghz :( I can post at 4641Mhz with 1.456V, but its no where near stable.

Do you guys know if the Core i7 930's are D0 stepping?
