Title: cudaminer settings for GTX 280 Post by: Jelz on November 29, 2013, 08:59:20 PM Well... I just cannot get my GTX 280 to go above 16 khash/s and would really appreciate some help considering I should get more out of it based on the GTX 260 results.
Autotuning doesn't come up with anything. When I use -D, it shows: D:\Litecoin\cudaminer>cudaminer -D -o stratum+tcp://netcodepool.org:3333 -O user:pass [2013-11-29 21:49:15] Starting Stratum on stratum+tcp://netcodepool.org:3333 [2013-11-29 21:49:15] 1 miner threads started, using 'scrypt' algorithm.

And I tried some manual settings like -l 27x3 -l 54x3 But the end result is always the same; "result does not validate on CPU!" What does work is -l F27x3 -l K54x3 But the rate does not go above 16 khash/s And I really do not know what kernel to use.. S, L, K, F,..? The known GTX 260 setting -l S27x3 Will then show: "using launch configuration K27x3" with the same (slow) result. Any help is appreciated! :) Title: Re: cudaminer settings for GTX 280 Post by: twerdster on November 29, 2013, 10:24:09 PM Im having the same problem with four GTX 580s . I have a GTX 690 and its running at 300KH/s for -l K42x7 which was found by hand. -D and auto tune showup nothing and cause a crash.
Cudaminer is crashing for my 580s. The only configuration that isnt crashing is -l K1x1. Any ideas would be great!

I tried more settings since my post, but none resulted into anything other than cudaminer crashes, booo's, unable to validate, etc.
I did get the card up to 22khash/s, but according to the pool I was still only at 14khash/s. Well, I have now decided to take a different path and purchase a 2nd hand ATI 6870 card.. Maybe it's too late to get my investment back, but heck.. it's fun to try anyways :) |
