I have done some test to see how much gain exist with memory o/c.
If anyone want to give us more from gaming/benchmarks it will be helpful.

All test are with the same cpu i7-970 at 3.8GHz and the 7970 at default core/mem voltage.

Memory Scaling - Sapphire 7950 Dual Fan OC

Over the weekend I used Hard Reset's benchmark to test the gains due to overclocking memory. I ran the benchmark at each setting three times, below are the the median results for each. Benchmark settings were max'd, including 4xFSAA. My 2500k is oc'd to 4.2ghz.

Stock Core = 900

1250 Mem = 77.5 Avg FPS
1300 = 77.7
1350 = 78.2
1400 = 76.9
1450 = 78.7
1500 = 79.2

OC Core = 1125 @ 1187mv

1250 Mem = 88.8 Avg FPS
1300 = 89.5
1350 = 91.6
1400 = 90.5
1450 = 91.5
1500 = 93.3

I did not overvolt the memory.
 
Nice results guys.Good to know some games add a few more FPS on the memory overclocks.
 
Nice, I'm running all 3 of my 7970s at 1100/1500 do I'm picking up some frames then.
