Hey guys,

Thought I'd add this to help those who may be struggling to get the most out of their 5970s.

I was running the 2.1 Stream SDK + 12.6/12.3 drivers and was getting 320Mhash/s across all cores (cgminer) with clocks at 800/300Mhz.

I spent the entire day tearing my hair out trying to get BF3 to run right on the quad crossfire and landed on drivers 12.1 only to boot up cgminer to see that I'm now getting 320Mhash/s at STOCK speeds and 370Mhash/s at 800/300.

So it would appear that for a machine used for gaming and mining this combination is your best option.

Transactions can optionally carry transaction fees. Whoever mines the block which ends up containing your transaction will get the fee. The Bitcoin client will sometimes force you to pay a fee when it thinks that no miner will accept your transaction otherwise.

Hey mate,

I use SDK 2.1, drivers 11.12, I installed the SDK via the WinRAR method of extracting and installing only the .MSI file.

Now I'm clocked at 1000 MHz / 350 MHz, and get 475 mhash/s per core.

375 mhash for 1000mhz on a 5970/5870 core is REALLY slow. Just saying.
You should easily clear 460 mhash at 1000 core speed for a cypress xt core.

Woops, sorry mate just a typo.
I meant 475 mhash/s.
