safe voltgae for 5850 with afterburner

[rippling]

i am about to try and clock my new 5850 i got today , if i ever get stiflash to work with dos boot usb stick grrrr

if i get it flashed what is a safe voltage to overclock the gpu to 1.25 or 1.3 ok? what settings should i go for first ?

its down to the temps really, core & VRM's... anything up to 1.35v is fine if the temps are low.

And Asus lets you go to 1.5v so as said, keep an eye on temps.

how did you manage that clocks on your 5850 , mine freezes on benchmark if i go over 940 gpu?

don't forget every gpu is different. 1 may do 900 with high voltage, where another may do 1000+ with lower voltage.

it's similar to cpu's

Voltage and watercooled.

That is my day to day speed. Previously with MSI my max was 1070 core with 1.35v and with the Asus bios and 1.5v it's 1110 but not worth the extra 60Mhz for the increase from 1,25v to 1,5v even watercooled.

And as said, every card is differenct. My first 5850 was a poor overclocker that wouldn't even be stable at 1000Mhz no matter what voltage.
