[Official] AMD Radeon HD 7950/7970/7990 Owners Thread - Page 1381

post #13801 of 38701
Well I finally got my loop up and my 7950 is a bit strange. It takes 1.25v to get 1200core, but with the stock 1.6v, it can do 1800mem no problem.wth.gif

1200core with 1.25v gets the card to 45C and up
1040core with 1.093v gets the card to 38C and up

Edit: Single RX240 rad with two 2150GTs in push (runs around 1000RPM), D5 setting at 3. XSPC Raystorm also in the loop.

My Unigine score isn't as great as I expected as someone with a 1100/1400 did almost the same as my 1200/1800 overclock.

your performance is lesser than pureblackfire's HD 7950 at 1150 / 1350 Mhz memory. his score is 1180. avg fps 46.8 min 22.8 fps. Maybe the memory overclock on your card is running into errors and reducing performance . GDDR5 will retry if transmission fails at high speeds thus reducing performance. try with memory speeds of 1400 - 1450 Mhz. And if you get better perf then slowly increase memory till you see perf increase and not reduction.

Sounds unstable to me. The memory seems very high. If you want to find stability with overclocks with the HD79 series, crysis 2 benchmark is a must.

I got a worse score with 1200/1400. Maybe my core is unstable, gonna try a lower clock.

Edit:

1155/1400



1155/1800 (memory OC looks stable since it does lead to a higher score with the same core clocks)
