The theoretically largest possible is your memory size divided by the thread size (Nf18 = 64MB) R7 240 4GB -> 64H / s -> but real only 29H/s-32H/s (it's a slow card) and you can't allocated all memory! Maybe use 70% for fast cards, I don't know. 8GB/64MB*0.7= ~ 89H/s ...
for the Ikarus pool use the --no-extranonce Option if you can, the pool do not Support extranonce!
Thanks for the answers, my doubt is for the following
According to the law in the previous cachecoin thread, the following cards had this hashrate with the modified cgminer version for scrypt-jane
[ANN] [CACH] CACHeCoin released based on scrypt-jane
<< <(196/520)> >>
Guys, can you tell me if my hashrates are OK? I'm using cgminer that supports scrypt-jane algorithm. I've read somewhere on the internet, that scrypt-jane hashrate should be something like 75% of scrypt hashrate. In my case, it is not
I'm not getting any HW errors at all.
Radeon 7970
265 kH / s (WU: 220 kH / s) - scrypt-jane
760 kH / s (WU: 690 kH / s) - scrypt
Radeon 270x
186 kH / s (WU: 195 kH / s) - scrypt-jane
465 kH / s (WU: 410 kH / s) - scrypt
Currently mining at 590kh / s and 635kh / s on my two R9 280X.
But that was in the past I do not know if those cards still maintain that hashrate if the code changes, I imagine it is the same, because in the old thread says scrypt-jane: 18
Finally, according to tests gtx 1080 gets 520 h / s
Has anyone corroborated these cards?
