I got ~10% hardware errors and ~10% lower hashrate mining at Eligius overnight, and switched to Btcguild this morning and the problems went away (my hashrate for November Jupiters went up by ~10% and the hardware errors went away at Btcguild).

October Jupiters using the .99 firmware don't appear to be impacted, but some November Jupiters running the .99e most definitely are.

I prefer to mine at Eligius versus Btcguild to support pool decentralization, but won't do so if it means a 10% hashrate hit.

I am not the only person having this issue. Check out the Eligius thread for more examples.

I received 2 November Jupiters yesterday that are both hashing at 670ghs on average at BTCGuild with a LOT of variance. The 72 hour graph fluctuates between 640-711ghs. My Oct Jupiter has much less variance at 560ghs average.
