GUIMiner Hash-rate is too low

[Malkavien]

Hi there,

I'm new to this.
I registered myself at BTC Guild and made some hashings.

I have a HD4670 grafikcard which provides around 25Mhash/s. But after a few Minutes it goes down to ~100kHashes.
Anybody knows why this is happening?

Best Regardes.

What kind of mining software are you using, and what settings are you inputting into the software?

EDIT: Ah, Guiminer. What settings are you using?

I'm using default settings, I didn't changed anything.

getting this:

sounds like the pool has gone down.

have a backup pool to switch over to

I recommend 50BTC.com and BitMinter.com
