Hello all,

I would want to overclock my Sapphire 7970 OC Edition to test out the Crysis 3 for benchmarking. But can i know what is the stock voltage for the card? And is there any successful voltage tweaks to share?

Using the Sapphire TRIXX overclock utility,

GPU Clock - 980Mhz
Memory Clock - 1465mhz
VDDC - 1025
Board Power Li - +0

Newbie here

Thanks a lot in advance!

sapphire i think hard to adjust voltage, because trixx utilities dont support voltage

Can't u just move the slider?

I think your stock voltage was 1050mv. though it could possibly be 1025mv also but it's hardly seen so I guess should be 1050mv default. here's some example of what you can achieve using Sapphire Trixx under watercooling. If air cooling, usually 7970 can be oc'ed up to 1200/1600 stable but you have to raise the fan speed. make a fan profile yourself.

better u use msi afterburner

seriously i really agree what he said ~ i hate triXX software so much

anyway if you are using ATI graphic card den i prefer you to use MSI afterburner ~

here is the link download here http://event.msi.com/vga/afterburner/download.htm

den click download MSI afterburner

the only reason i choose msi afterburner is it can unlock voltage with just one click.

there is no need to flash the bios. : )

lol trixx is one of the best oc software compared to msi afterburner for 7series

its more stable and it works

use the 4.40b mod.

What >.< !!!

are you serious sir ??

i thought MSI afterburner is better ~ i dislike TriXx because something it not working

trixx is the best and it works
no idea whats happening on ure end

try getting the 4.40 mod version

only flaw i know of is u need to disable monitor sleep timer

no problem overclocked to 1200mhz and run for 3 days full load without any bluescreen or error.

of course with msi afterburner.
