Hash rate dropping

[skypatrol]

No idea why my hash rate is dropping,
I was getting 256 Mhash/s
now i am only getting 8 mhash/s
nothing has changed, i even overclocked my CPU
no other processes are running

try other pool...or restart your pc so can driver can load again...

Overclocking CPU is irrelevant since your miner should not be maxxing any of your cores anyway. (Mine runs 0 to 5% at any time with four GPU's going).

- Your pool is not providing work fast enough. Try another pool or add backups
- Your GPU is quasi-crashing because of some kind of problem with its clockspeeds, power supply, heat, or it's damaged permanently
- Your computer has an extreme bandwidth limitation in the PCI-e port and/or subsystems that interconnect it to the rest of the computer. On cheap motherboards this is a common problem. On my PC my hashrate drops by 20% when one of my storage devices is transferring data. Even the network port when heavily in use slows my hashrate. It's because all of these devices share for resources on the motherboard (eg. chipset / southbridge bandwidth).

BTC or altcoin?

BTC or altcoin?

You're question is really SHA-256 or scrypt algo coin. If he's getting 256 Mh/s on a scrypt altcoin I will buy his card for $9999. So we can assume it's BTC, PPC, or TRC (the common non-merge-mined SHA-256 coins)
