Hi,

three days ago I started to read about Bitcoins and played around with it a bit. I also bought some Coins (yes, I know - expensive at the moment, but it was more 'toy shopping'), got a bit familiar with bitcoin-otc, chatted a bit and read a lot of long threads and many videos.

Now I am playing around with mining. I am running Windows with a Radeon HD5770 on a machine that runs nearly 24/7 anyhow. So I invested the extra 60 - 65 Watts to let the Card do a bit of work. It does not work a lot (up to 213 MH/s) but I am not here to try to get rich. Wink

I do have a little technical problem and since I may not post in the tech support forums yet, I ask here:

If the GPU is IDLE it should reduce the GPU clock. (e.g. I am not mining and do desktop stuff) When there is load on the GPU it should go to full clock frequency. If I start GUIMiner core clock and memory clock go to max, stay there a bit and then both are constantly switching up and down running about 15 seconds on IDLE speed (hashrate drops to 120 MH/s) and then go back to full speed for about 5 seconds hashing with 213 MH/s again. Anyone seen this before and fixed it? Don't want to run the GPU on full speed constantly by editing the BIOS by removing the power save modes.

Have a great day!

Hi and welcome. I'm confused by your question though - try disabling ULPS to prevent the intermittent reclocking if you mean that.

Perfect! That did the job! I did not know about ULPS and since there was no option to disable it in the Programs I used...

Thank you for your help. Mining runs at 212 to 214 MH/s constantly now. So I can use the last few days of a difficulty under 10.000.000

No problems, just remember to stop when the difficulty rises too high.  Cheesy

Yes, it not generating a lot already. The extra Watts the machine burns might be paid at the moment but running it for mining only would be 300% more electricity than the bitcoins pay. But it is more a toy than a business anyhow. Wink

Impressive! What are you hashing on? Radeon 9800Pro? Wink
