How do I calc the memory clock and gpu clock speed?

Do I times the clock by 4 to get the effective clock?

Okay so GPU-Z says:

default is 1046/1502 and the actual clock (with my OC) is 1096/1752

So my memory is running at 7,000Mhz wow!

correct. is it stable? i cud only get my memory to 6428. So ur lucky. what did u stress it with? did u go up on your voltage?

It is stable using 3d mark 11, evga's stress test (after 30m no artifacts) and I did up the voltage. BTW I OCed the gpu up to +75 and still stable.

Here are my settings:

Power Target 110%, cgpu +75, mem +500, voltage 1050mV, and I changed the fan speed map. I put the fan speed at 50% for 70c and it goes linear up to 100% at 80c. It doesn't go past 71C and is still quite.

My case's airflow is:

2 120mm 79cfm intake front
1 140mm exhaust top
2 120mm 79cfm in push/pull with radiator exhaust out the back.

You used EVGA precision then? If so, maybe I'll try it. I used MSI afterburner and haven't played w/ voltage yet.

yeah I use evga precision and evga oc scanner. From what I have heard is I'm lucky to have got +75, +500.
