I have a brand new MSI GeForce GTX 580 Lightning for sale.

Asking for 45BTC. Local transactions preferred. I'm in Los Angeles, CA.

Obviously not a mining card...

There's been a lot of discussion for the Sapphire HD 5850 Xtreme all over the place, making it hard to find important information.

Let's have it all condensed into one thread. I'll start first by posting my current settings:

I use Sapphire Trixx to change voltage and MSI Afterburner to change clock and fan speed.

HD5850 Xtreme CrossfireX
ULPS Disabled
Voltage 1.150V
Core: 945
Memory: 300
Catalyst 11.5 / SDK 2.4

357MH/s

I tried 1000MHz @ 1.200V but it got kinda hot so I dropped it down to 1.15V and worked from there. At 1.15V, 950 core, I had a few instances where the miner just stopped mining (no errors or anything) and GPU load dropped down to 0%. So now I'm running it at 945 core and seeing where it takes me.

Post your settings!

Just wanted to start a thread on Catalyst 11.5. I haven't updated yet but discussions are welcome.
