turning down gpu usage? How?

[techman05]

My laptop I want to use for low hashing of bitcoins. I want to lower the amount of usage gpuminer is using on my card. I do the -f 60 but thats probaby for proper pcs with alot more air pass through.

Its doing about 3.4 Mhashes but I'd like to get it to be about half that without loosing out on missing hashes and my pc shutting down.

Thanks

3.4 MH/s, nevermind half of that, is basically nothing when it comes to mining.  You'll mine about 0.0003 BTC/day with 4 MH/s at current difficulty.  Combined with the power cost (more than 0.0003 BTC) and the wear on your laptop (mining on a laptop is a bad idea in general), my advice is "don't do it". Sorry :/

If you want to play around with mining you're better off using a desktop machine with a GPU you already own or buying a FPGA miner.  You can probably pay $200-500 for a used FPGA and actually make a measurable amount of btc without killing your laptop.  You could even buy a used video card for ~$100 (try to grab a AMD/ATI Radeon 5830.. you'll get about 250-300 MH/s) and use that.

But to answer your original question, I don't know.  Sorry again!
