Yeah it does help, thanks.
Have you figured out a way to see that it actually does pick up the diablo kernel?
Topic: Sudden Bump in the Hash Rate (Read 725 times)
I get about 560MH from this:
7950 @ 1075mhz with 1.012v per afterburner under Win7 (memory at 625mhz with 1.5v)
cgminer 2.7.5
Core temps run 76C-73C
VRMs run 75C-80C (hottest)
I can overclock it much higher, but this is a very good noise/temp solution for my card. It's also very stable.
"kernel" : "diablo",
"intensity" : "9",
"gpu-powertune" : "20",
"gpu-threads" : "2",
"worksize" : "256",
Hope that helps
Oh, yay, post #5.

On which card and under what settings and environment ?

I guess I was trying to understand what the "best" miner was, and from there I would tweak settings. The board is a Gigabyte HD7950 3GB, standard board (ie not the OC board), but it does oc a bit before getting flakey - I haven't tweaked it too much, I am running for a while to get a baseline. So currently it is 950Mhz / 1285Mhz.
With cgminer, I haven't changed anything, I am guessing it is running dynamic aggression. This is under Windows 7 64bit, but I spend an equal amount of time in linux, but not with this card yet. My nvidia board under linux and rpcminer seemed to run about 30% better than with cgminer under Windows, so it will be interesting to see how this card goes.
I am getting 475Mh/s with cgminer.

So you were probably all wondering what the sudden bump in the hash rate was all about? Well, that was me, retiring an nVidia 570 for an AMD 7950.
Yeah, I know. A full .5Gh/s
Well, ok, it made me smile anyway.
I have been trying out various minors with this. I have the 2.7SDK and 12.8 drivers installed, and for some reason, phoenix 2.0 won't enable BFI_INT - unsupported. I am guessing the latest phoenix isn't compatible with the 2.7SDK? Without it, phoenix performs worse than poclbm or cgminer - at least with my setup.
Is there a "best" miner I should be using? I am getting 475Mh/s with cgminer.
Thanks...
