Oh yeah, I remembered what I wanted to ask now. About voltages, how much can I use? I think I tried like 1.48v gpu and 2.05v mem but as I said I still haven't removed stock cooling, even to look underneath it.

Careful you don't melt those DigitalPWMs off

so they all run hot do they

It's a case of contact area - Volterra do make them with different surface areas, Blackops has big ones, abit did not. Problem is if they are not implemented well, abit on early boards had a flaw were if one of the ICs overheated it would shutdown, however this meant the other 4 had to take up the slack -> they got hotter -> shutdown cascade. If it's done well then they should run pretty well, and hopefully the cooling solution is well made *read braced underneath* as contact is everything with these parts.

well i am at 1.61v on stock cooling... 972mhz..... not a single problem SO FAR!!

790i SLI FTW Digital(a mouthful..) works fine up to 5GHz on air

Haven't measured PWM temps yet but it's working so I'm not asking any questions.

**loonym** · 10-04-2008, 04:13 AM

Thanks for the tip Bong

Managed to up my 03 score a little

I put around 1.64vgpu and 2.09vmem.

**JamesBong420** · 10-04-2008, 07:18 AM

cant quite see your clocks... what are they?

**loonym** · 10-04-2008, 09:29 AM

lol... I didn't realize they were covered. 939/1030. I'm going to rerun that too, I want to try experimenting with drivers because my 01 still sucks

**loonym** · 10-04-2008, 09:50 AM

This is the cooling I put on last night...

And an 03 run I did playing around before I swapped out the q9650...

If I had better cooling I wouldn't even bother with the e8400 but I can't get this q9650 over 4.3ghz

**[XC] gomeler** · 10-04-2008, 03:54 PM

Will update the scores tomorrow. I've been a terrible host

Keep on pushing it, 1GHz core is calling your name.

I'm definately going to be trying for 1ghz and above but I want to get at least one decent 01 score up before I start trying to kill the card

**STEvil** · 10-04-2008, 09:40 PM

Got a heatsink rigged up today, just have to mount it.. and dig out my VR's.

Would have done that as well but I got sidetracked working on my 8800GTS...

**dinos22** · 10-05-2008, 08:44 AM

guys how do i mod the RAM to reduce the volts to try improve clocks

i'm back benching the card on air

**loonym** · 10-05-2008, 09:25 AM

What's the lowest yours will go Dinos? Mine are like 1.97v

**Johnny Bravo** · 10-05-2008, 09:26 AM

you can mod the potential divider Dinos normally we vary the resistance between the divider setpoint and ground - if the vary the resistance between the divider setpoint and the memory voltage you can effectively decrease the voltage.

lowest atm is 2.15v

hence why i want to reduce volts

**dinos22** · 10-05-2008, 09:34 AM

btw my air benching seems to be producing similar results

985/2160/848

about 90% stable but doable heheheh......

**Johnny Bravo** · 10-05-2008, 09:43 AM

don't joke I'm moving from LN2 to water - think the Qimonda chips don't like the cold as I can't clock anywhere near what I had under the chill

**dinos22** · 10-05-2008, 09:51 AM

i dont think its the cold but voltage
it's

ing odd

ok so it seems 1.74v load is max i can give it
i am at 972/2106/848

lobbies are giving me issues with voltage

**dinos22** · 10-05-2008, 09:56 AM

holy smokes
390FPS CH with 169.21 drivers eeek

**Johnny Bravo** · 10-05-2008, 09:58 AM

damn you! I cant get higher than 1.71 volts or the card cuts out!

Time to put a fire under your ass with some bad ass results me thinks

Strange the lobbies are giving you issues as it was dragothic low and high for me

**dinos22** · 10-05-2008, 10:04 AM

they can run higher but lobbies will cut out
i've tested 1.8v nature loaded

RAM is killing me
but i also must be messing up my LOD for Dragons
they are weak

**Johnny Bravo** · 10-05-2008, 10:10 AM

well I was running 980 core 1100 memory on all except dragothic, which had to nosedive down to 920/1050. That put me a 69k but I'm certain if I can get dragothic to play ball I'll be smoking past 71k
