Hello,

I just recently started running a 7970 card for Milkway. I have been running NVIDIA cards for the last decade and am new to recent AMD cards. I am noticing in both Linux (Slackware64 14/Ubuntu 12.10) and Windows 7 64 that there is a fairly significant difference in run time from one task to another. Generally when I first start BOINC, the first task will run 41-57 seconds. Then most every other task after that runs 61-93 seconds. Is this normal?

I have no other load on the CPU and have disabled EIST and C-states power savings features. The GPU has a factory frequency of 1100 MHz but runs at 1050 MHz with this particular project and the memory frequency is 1500 MHz. GPU temperature is 55-60C under load. I see no indication in OverDrive that the GPU frequency is dropping under load. Thanks.

The time variations are normal. The biggest difference you can make is to lower your memory speed. Milky Way will not make use of it and it just consumes power and produces heat. I run my card's memory at 300MHz and it stays nice and cool.

Thanks. I will try to lower the memory frequency. Any extra power savings will be good to have.

BUT if you want to run TWO units at once swiftmallard has the key to that too! Cooling is the key to that, so if it runs too warm it is not a good idea to try.
