请问OP大神 是middlecoin好一些还是Clevermining收益更高？ 我是看了这个帖子的比较https://litecointalk.org/index.php?topic=15124.30 请问有类似比对的经验不～～？谢啦

Guys, what is the kind of CPM to expect on a 280X?

I get around 3373 c/m at stock 1000/1500 and 3500 c/m at 1050/1500.

3500 c/m at which algorithm you run? -1, -2, or -3? My card only has 3200 cpm at -2.

2x Sapphire R9 280x vapor-x oc 3gb ddr5 384bit
1 psu chieftech super 750w

My bat file: clpts_x86-64.exe -u x -p x -t 0,0,1,1 -a 2

Miner version: clpts-v0.2.2_win_x86-64

Undervolted as follow:

Core voltage (mv): 1094 mv
power limit: 0
core clock: 1055 mhz
memory clock: 1500 mhz
fan speed: 56%
Temp: Gpu0 - 66 oC
           GPU1 - 55 oC

Hi znakistu, I have very similar config just like you. My two 7970 are Sapphire ref. design cards. I flashed them to GHz bios (with default voltage 1.162v), which mean now they both have 1050/6000(effective), and yours are 1055/6000. Just wondering how stable have you run under that voltage, 1094mv? I am thinking to undervolt it but not sure how to test it, because the ref. design, my cards are now 85 oC and 82 oC. Hoping I can under volt it and give me some temp down. Can you share me your experience?

@NaN, our 7970/280X are all at sweet point with your num. 2 algorithm... It is weird. I tested each alg. one by one.

The Tahiti improved in clpts 0.2 is significant, which used to net1200+ (similar to 680/670) in its  v0.1 or any other miners now. I believe only clpts 0.2 makse a big step. If as you said, pts is designed by sha512, ,which should make no different, then I believe cuda has no reason behind AMD.

Hi abc123, will be any performance improvement for Cuda? We all know AMD is much much faster. :-(

"AMD will is much much faster" is not true for SHA512, it is true for SHA256 and scrypt.
I don't think more significant performance increases can be made on GTX 660.
10~20% performance increases may be possible, but needs a lot of work.
Greate performance improvement for Tesla etc may be possible, or may not. But Tesla card is very expensive,
and whether the performance can be improved is uncertain, so I have not made decision to buy one.

My friend's R9 280X can have 3100/3500 (default/OC) cpm on clpts-v0.2.2, and my gtx690 has 2200 cpm in total. I believe this means AMD now is much faster in SHA 512, single chip beats my two. clpts also asks for 2 threads for each chip like your miner, apparently, it is much more efficient and optimized.

Hi NaN, any update for CUDA miner so far?

Please try to release Nvidia edition with equivalent cpm ASAP~~~ thanks a lot. My GTX690 only has 280x speed in ptsGPUz, come on. T.T
