How stable is your hash rate?

I have 2 rigs running and the hash rate fluctuates on all 5 cards.

Cards are 7970s and the hash rate keeps changing between ~700Khs to ~712Khs.
If I move the mouse the hash rate on all cards drops down in the 600s and then climbs back up
to the 700 range.

Just wondering if this is normal or if I still need to do a little more tweaking?

Normal

That is not happening on my rigs! Rock stable hashrate, but unusable machine.. I run reaper!

This is normal, but sometimes causes the driver to fail. This happens on 2 of my 5 rigs.

Normally upgrading your system ram will fix it. If you're running a single core CPU, you're probably out of luck.

Glad to hear that it's normal ... I still want to try putting in a cheap graphics card(6450) as the default, then disable it in CGMiner. I think that will increase the rate on the other cards by 10-15K or so and it shouldn't vary as much.
