Under/Overclocking 4870

[oli_ramsay]

I want my card to run at 250/250 when idle and 850/1050 in 3D. I don't want to mess around in the BIOS and I'm perfectly happy doing in manually. The only problem is that Rivatuner wont allow me to go that low:

Is there any other software which lets me go any lower? AMD GPU Clock tool doesn't seem to work with the newer drivers. Not sure about ATi Tray tools.

Thanks in advance

bump... anyone?

That's an easy fix.

Change the "MinClockLimit" value shown above to "0", and hit OK. Close Rivatuner and open it again.

Your GPU and MEMORY clocks should go down to 75MHz and 90MHz, respectively...

i used rivatuner to get my 4870 up to 860mhz core and 1120mhz memory http://www.techpowerup.com/gpuz/kuw6s/ works great

Do you use the reference cooler?

Do you use the reference cooler?
