^^ Nice job done by you. You can stretch it further by tweaking the voltage.

Hey jas good job., it's helpful for me as a recent benchmarking of GPU i'm planning to acquire., thanks.

 

[Jaskanwar Singh]

thanks d6bmg and devx

UPDATE -
played upriver(BC2) with 900/1300 (stock volt) and found it stable. anything above for core wasnt stable in BC2 at stock volt.
so final clocks at stock volt -

memory didnt contribute much to increase in performance. so keeping it at 1275.

Nice OC for core. But memory seems low.

 

[Jaskanwar Singh]

thanks skud. i pushed memory to 1300 and it was stable. myself didnt go above still.

 

[Skud]

Load temps at OC?

 

[Jaskanwar Singh]

The temp was 68C~ at 68% fan (used a temp-speed proportional fan curve in afterburner) in BC2.

Great Job Jas !!!
Even I want to try my luck at OC`ing but can`t find the time to do it ...

keep up the good work ... OC further by tweaking voltages this time ....
