Title: Sapphire 5850 kh/s
Post by: jsgh on January 10, 2014, 11:30:30 PM
I'm wondering if I'm around target for a 5850.  I am getting a stable 372 kh/s out of each card.   I try to OC gnu to 900 and memory to 1175 and one of my two cards goes sick and then dies.

I got max 305 kh/s when I tried Scrypt mining with 5850, 372 kh/s seems very good to me

I use work size 256, G 1, thread concurrency 7168, gpu engine 880 and gpu mem clock 1175.  cards run stable. 

I read somewhere a guy was getting 400 kh/s by using gpu engine 900, but every time I try one of the cards dies after about 2 hours. 

oh well, I guess 372 is pretty good.

According to this you're a good bit ahead of the average hash rate for the 5850.  Of course the cards will vary themselves, just OC them individually as much as possible and find the stable plateau?

with cgminer can you specify different OC commands for each card?  it makes sense that you can I guess, just never tried.  I will do that.

Thanks for the tip!
