Is there anyone running an OC'd four module Avalon on p2pool?
I seem to get the same hashrate (90GH) at 325 as I do at 300, except with more heat and noise.
And I don't think it's a problem with power or cooling because if I switch to a different pool it hashes at around 105GH.
What's your GetBlockLatency like? How fast is the machine running p2pool? To me (not having anywhere near that hashing power) it seems like p2pool isn't able to provide work fast enough?
If you want, you could point your miner at my node for a few minutes (0.25% fee) and see what it reports?
