My XFX HD5770 Overclock

I don't think 1137 is too far from the stock voltage. Try it at that, and see if it's stable.

well i got a stable OC @ 1000MHz core and 1400MHz memory. it reaches 72 degrees celcius in crysis max details 4x AA @1280x960 and idles around 45 degrees celcius. is 72 degrees to hot? i dont think it is but some input would be nice.
Thanks to everyone who helped my with this OC, really appreciate it Now time to change my SIG

That is 900/1300MHz and is the maximum overclock possible without flashing the BIOS.

You don't have to flash the bios to go higher http://www.techist.com/forums/f10/s...ock-block-msi-afterburner-225554/#post1773313

Nice What voltage did you end up using?

Most graphic cards now are rated up to 90-100C on load. But try to keep it below 80-85.

I got Afterburner to overclock above 900 but I left it on overnight (folding) and I woke up to it running at 80C. Afterburner somehow let the voltage increase from 1.174 to 1.649 even though I didn't tell it to. What happened here, I doubt I'll use afterburner if it fries cards like that.

nice clocks!

I ended up using 1.2 volts exactly and it seem pretty stable.
