I think I now know what you mean...  LTC stats:  "Time Since Last Block   63 Hours 23 Minutes"

ohw... ehmm... yes.. I see.. just no luck then..   

Hi Flound,

I was mining LTC with Multipool for 48hours until this morning and have seen my balance grow with about 0.02.
I was mining with 290kh/s (apart for 3 three hours with half that rate) using the EU pool.
I see a lot of accepts, just a few rejects and no HW errors; everything on cgminer side seems normal.

That balance growth just doesn't seem right. Would you be able to see what is going on?

Thanks,

Since at least half an hour scrypt is available again also (on EU, have not checked US).
Site has been up for some time as well.

Horrifying to loose coins like that. I have an encrypted wallet. And that is backed up to another computer in my house. And it is backed up to USB. And still I feel i could loose something...   but I guess that is cause of my past working with Word Perfect 4 / 5 ... lost big parts of scripts when I did not save and it crashed again .. and again...

Okay, so no tips and such? 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 

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:

And then cudaminer crashes.

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!
