Overclocking my Vapor-X 7970 - Page 2

post #11 of 14
Thread Starter 
Well, so far I`m up to 1225MHz core and 1675MHz on the memory clock at stock voltage (1.256V). That gets me a score of 1813 on Valley. Increasing the voltage to 1.3V, I went up to 1235 core, but then the GPU temperature went up to 69C and the mem temps to 72C. I think I`ll just run my card at stock clocks for a while, and if I ever feel I need the extra power I`ll up it to the stable clocks at stock voltage.

At least I have an idea of what my card can do. Thanks guys.

How about the memory voltage? 1600 would be very low for a 7970 AFAIK. All 7970s ship with at least [?] 1500MHz on memory, so they get the quality Hynix stuff. The 7950s @ 1250MHz get the bad samples. So if you're only getting a 100MHz oc on the memory thats a tad disappointing. Just make sure its at 1.6v and not 1.5v


Well currently im away offshore at work so i cant do anything before i left ; i thought my voltage was locked at 1.256 but ive had a read on forums and it seems that if you delete the ome file in AB you can edit the voltage.Hopefully that works

Also i was at first testing for artifacts in Heaven (cant remember what version the one with the floating ship and islands) i had good results and got to 1200/1600 quickly with no artifacts on stock voltage (1.256 thats pretty high for stock) i then tried Furmark and got some artifacts raghu78 says to ignore and bench with other software that so maybe ive got 1200/1600 on 1.256. I will have to wait for a another two and a half weeks until i get back from work and can overclock it again.

Is the you card the double 8 pin version ?
