Config help

[jacoby0419]

Ok, so I'm not a total noob- but still relatively.

I initially setup a 7850 rig and am getting ~350mh/s out of it and am happy with that (unless I shouldn't be).  His weekend I setup a 1x 7950 rig (these are two separate pc's) and am only getting ~485 mh/s where I think I should be getting 550-600.

I'm using guiminer with flags set -v -w256

Any tips on what else I can do?

PS- I was using 50btc, but got tired of their site being down half of the time I went there.  Using btcguild now.

Thanks for the help!

Have you adjusted the GPU Engine/Memory clocks? I would recommend using cgminer rather than guiminer, as it will allow you to adjust these.

I have adjusted them, I pushed the memory and processor to max before artifacts would appear.  That gave me a bit more- but it seems to max out at 550 and seems to just want to chug along at 48-500.

It's sitting in a PCI-E x16 2.0 slot on a 3.0 C2D system (I had it laying around).

It's a HIS card, do you guys think that's what the performance is due to- would I have better luck with a MSI, ASUS, or other better brand?
