Just tossing my confirmations out there:
Sapphire 5830s:
Pair 1: 264 Mhash/sec -> 271 Mhash/sec (each) at 875 MHz GPU, 900 MHz RAM (2.58% increase)
Pair 2: 273 Mhash/sec -> 281 Mhash/sec (each) at 900 MHz GPU, 600 MHz RAM (2.84% increase)
I'm also tracking Rejected shares.
Before Patch:
Pair 1: ~2.6% rejects (after 800+ shares)
Pair 2: ~3.2% rejects (after 800+ shares)
After Patch:
Pair 1: ~3.0% rejects (after 650+ shares)
Pair 2: ~4.0% (after 750+ shares)
So, the increase appears to also cause additional rejects that should be discounted from total increase gain, cutting it down a full 1% in my case.
