Edit:
Retested 1200/1800 with 1.3v/1.6v.... looks like you were right about needing more core voltage. Now I'm sad that it takes 1.3v on water to reach 1200core for my card. thumbsdownsmileyanim.gif

I'll do more testing after work today and see if lower memory can grant me higher core clocks. Thanks for your advice!

you make the same score i do with a lightning 7970 @1250/1600 so, or your score is awesome or mine is crap

Aluminium is that metal.

Try heaven benches at a stable core speed and voltage and increase the memory with slow amounts.
100mhz max increase every time. That way you will notice when error correction kicked in (when fps dropped compared to previous run)
Good luck thumb.gif

It's a worth a try. I will update this post as I test.

1200/1300 - 1.3v/1.6v



1200/1400 - 1.3v/1.6v



1200/1500 - 1.3v/1.6v



1200/1600 - 1.3v/1.6v



1200/1700 - 1.3v/1.6v



1200/1800 - 1.3v/1.6v (reposted, not a new test)

It looks like my memory OC of 1800mhz is definitely stable as there is a linear performance gain from 1300~1800mhz in steps of 100mhz.

Will test more later today as I have work in 5 hours. tongue.gif

No it is not wink.gif

In the beginning you almost get a full frame advantage.
In the last test it is just 0,6 fps anymore - error correction !
I would set the memory to 1600mhz

Is that how it works? I only reposted the test I took earlier for the last one, but I'm too tired to run more tests. Thanks for your tips though, I will try to confirm by tonight.

Yep, thats how it works.
By the way, the gain in frames you get from 1600mhz to 1800mhz is really not worth it. Chances of the memory error correcting are just too high compared to the gain in performance you get.

Your sweet spot is 1200 core and 1600 memory. your best min fps is at 1600 mhz memory. so you can be pretty sure after that error correction is setting in a bit. and even though 1200 mhz on water might be disappointing the perf you are getting out of that card for which you paid USD 350 is amazing. As said above people with MSI HD 7970 Lightning (1250 / 1600) are getting the same perf you are getting. And not to forget the MSI Lightning costs USD 530 . so its still very decent perf and amazing price perf. you should be happy. thumb.gif

where did you get the card for such a low price and is it a new card or a used card ?
