Need some help please! Getting 2.6Mhash when I think I should be getting 150+

[dragonboltz]

Hi, I'm very new to this kind of thing and am trying to get the best possible Mhash/s using my GPU.

I followed the directions on this forum and got the Gui installed, made an account on bitcoin pool and got everything working, except I'm only getting 2.6MHash/s with this, which is about as much as I was getting just using my CPU with bitcoin.

The hardware comparison list says I should be getting 150Mhash/s + with my GPU - ATI Radeon HD 5770.

I'm probably making some basic mistake somewhere but I'm not computer smart enough to find it, any advice would be much appreciated.

please see pictures for my specifications and setup. ( I tried uploading them here but it said the upload folder was full)

you're currently mining on your CPU,
in the miner GUI, click on Device (where it currently says "AMD Athlon...") and choose your GPU (device 1 instead of 0),
that should do the trick.

Hi, that would make sense, but when I click the drop down menu there aren't any other options??

hmm, maybe a driver/SDK issue, try to reinstall those (i'd recommend to use SDK2.1/2.2 instead of 2.3).
