4870 1gb memory overclocks?

[Columbo]

What can I expect to overclock the memory to?

Currently on a slight overclock of 1000mhz in Cat 8.12, what are other people achieving?

I have the powercolour 1 gig and i have tried 780 gpu and 940 memory and on 3dmark06 i seemed to have lost a few points so not much of an overclock.
Maybe my CPU is holding me back??

ManuCuBs try out the in the pink benchmark "its in another thread" see what you get.

Think that mem clock is the optimum oc the core and see what happens to benchies!

Well the below seems stable:

800 core / 1000mhz memory

Everything stable. Should I expect much more?

edit: ignore the fan control settings, Ive got a Accelero S1 on it with 2 92mm fans.

wow nice i only see 790 on my max gpu clock you have 850.
Did you see a reduction in the temps on your card with the new cooler??

Same here on the Powercolor. Only 790 mac in CCC. How do I set it higher? Different bios?

Mine came with the 'toxic' style black cooler and it was idling around 60c and sounded like a jet engine when it warmed up.

I fitted the S1 with some AS5 paste and 2 92mm Xilence fans connected to the motherboard headers and its knocked around 20c off it.

The temp is taken in the screenie is as I've literally just exited about an hours session of COD4 and is still cooling back down.

Dunno on this mate, it came with that when I bought it. Mines a Sapphire though if it makes a difference.

i've got the 512 version and i've clocked mine to 800/1000 and it gave me over 1000 points on 3d mark.

suprised about the toxic fan though. Shame you've had to take it off as the card looks great with it on and mine is silent/cool

To be fair to the card mate, just about all of my setup is fanless. Got a Noctua 120mm on my CPU cooler and the 2 92mm's on the S1 and thats it. So any noise from it was going to be heard, even my PSU is fanless.

 

[magicroundabout]

fair point. if you've a fanless setup then the slightest bit of noise will be heard!!!!

My front 120mm Fan is noisy as hell and needs changing. I have unplugged this to see what the noise level is like and over my CPU cooler and exhaust fan i couldn't hear it which i was pleased with.
