Srry to say that, but I'm SO HAPPY to see your problem.
I got the exact same problem, asking all over the internet in various language and seems to be the only one until now.
I have 3 290 that do exactly the same: start at 2500 then get back to 2100 (all in the exact same second) after 10 minutes. I'm under Bamt, and it only do that with the 290 AND darkcoin. No problem in Scrypt, no problem in Darkcoin with my other kind of cards.
If you (or others) found a workaround, do not hesitate to share. I'll be glad to offer a few Darkcoins to someone able to fix this.
The quote train was getting a little long there lol.
I'm sure we're not alone. I'm using windows 7 . . so clearly it's not our platforms. This leaves something specific to 290's or the miner/kernel.
Anyone have a clue?
Are those 290's hitting 95c?
With full fan power they are under 45°, so it's not the temperature.
I tried some custom bios without any results.
I change the motherboard without any result.
I only have ONE clue: All the cards looses 10% hash at the exact same second. If there was some card issue, I doubt it happened at the same time, no matter what the temperature difference there is.
I'm not qualified to fixed this anyway...

Could you look if your drop happened at the same times?
I run a bamt linux rig and have the problem.
I had another card on the same rig that has No drop (a 270x).
