I am surprised that there are only 19 7870 members. I thought this card is a popular mid-range card.

Seems pretty normal to me. Mines around 55 on load at 1120/1250 on the Twin Frozr III cooler.


Once again though I'd recommend trying to lower your memory speeds. I believe you'll get higher benchmark scores. As someone else on here taught me, after a certain speed the error checking the memory starts doing actually becomes a detriment to scores/FPS.

For me its 1250. Thats the inflection point on my card. 1260 my futuremark score starts dropping. A small amount mind you, only about 10 points, but drops nonetheless. Drops increasingly lower as I up the memory speeds accordingly. Try around 1200 for memory and compare that to the scores you get on futuremark now.

Yeah, I also noticed that the memory act weird on these cards. Going from 1200 to 1250 gives me a nice performance boost, then the next boost is on 1350 with anything in between causing the performance to drop. I would assume the next performance boost to be at 1450, but I can't get it stable there.

The best way to OC these cards is to max out the core and then look for the memory sweet spot. The core on mine can go up to 1245 with 1225mV, but I settled for 1230 at 1212mV in order to keep my temps just below the 70c mark.

Not really sure why you would oc past 1050/1250, other than to increase benchmarks. I have my 7850 set to 1050/1250 and I crush bf3 on full ultra paired with my fx8350.

For e-penor

It makes people feel good if their 7850 can overclock to reach stock 7870 or 7950 performance.
