Bad pool, or flaky ISP connection.
On a side note your memclock is way too low you should add another 0 to the end of that.
Uh, no. Memclock has no affect on hashrate with quarkcoin. Lowering memclock saves energy. As for the 'Waiting for work' it matters not if the memclock is 1500, 1250, 700, or 150.
Any one else have any other ideas?
ahh, gotcha..
I wasn't saying memclock was causing your connection issues, that's either a bad pool or bad ISP connection.
