Hey there,

I'm just wondering if anyone would be willing to give me any suggestions (beyond buying a new computer) to improve my hash rate.  I have a Intel Core Duo 2.28 w/ 3 GB L3 cache.  Unfortunately I'm sitting on a ATI Mobility 3400...so no GPU mining for me.  I'm running jgarik's (I think that's his name) miner and only getting roughly 300khps with 2 threads and the cryptopp algorithm. The 4way algorithm seems to be popular, but I can't get above 200kbps with it.

There was a fellow on the new pooled mining thread saying I should be getting proof of works every 6 minutes or so.  I can't get 1 in 6 hours...more like 12 or 13.

Try this SSE miner. I'm using a Core 2 Duo E8400 and my rate increased from ~2mhash to ~7mhash.

I'm on Ubuntu.  Would switching to something on Windows really be faster?

I'm legitimately asking, not being sarcastic.

I can't really comment on the Windows vs Linux issue, but I can vouch for the SSE2 miner as being at least twice as fast as the other CPU miners on an Intel Core 2 Duo processor.  With normal miners I get 1000 khash/s, while with the SSE2 miner I get closer to 3000 khash/s per core.  Granted, it runs the processor quite hotter than most applications so I typically only use one core at a time for CPU health reasons, but that's what it is.
