Topic: GTX 680 Mining IS Profitable (Read 14231 times)

Nope bitcoin mining needs good integer performance and that is something no nvidia device has. Drivers and software can't fix that.

Actually I estimated here that the GTX 680 should be theoretically capable of 300-475 Mhash/s (it still sucks compared to AMD GPUs though).

okay, how to get that?

TDP says 62% load 98->99%
118->120.5mhash

with youtube playing, gpu to 1280mhz memory only boosted 52mhz dont think that matters for hasing

No, memory clock does nothing for mining. In fact, underclock the memory to slightly decrease heat output and reduce temperatures. Put it at like 700-900 mhz when mining for extended times.

with 5970 I found that memory as 1/3 of clock gets significant increase in Mhash rate

Well I guess you estimated wrong then.

Hmm.

Spend $500 on a 680 GTX and get 120 mhash overclocked.

Or...

Spend $250 on a 5970 and get 650 mhash undervolted.

HMMMMMMMMMMMMMMMMMM............

If you want to use square wheels on your vehicle, then by all means... it's not going to be the most efficient or fastest route though, and people will probably point and laugh at you or give you weird looks.
"Yeah, I got square wheels, but I can still make it to work! I only have to pay half my paycheck in gas too!"

OR

already have a 680 for editing

on off time use it to mine

You write your own miner and properly optimize it to exploit the performance of the GTX 680

OK be back in 8 months

EDIT: I'll give 4BTC to anyone can get me 300+Mhash on it
