Title: Problems adding more cards - r9 280x Post by: merkin on March 04, 2014, 02:40:34 PM Heya Guys I finally made a little open case so I can start adding more cards to it.
I was running a Sapphire r9 280x in a standard case and Now I got a new mobo H81M-Plus with a celeron chip, and 2GB of RAM and I bought another Sapphire 280x I am running them both on pci-e powered risers on 1x (Comp wouldnt boot with having one in the 16x on rise) tl;dr Anyway I'm getting pretty low khash now... than I did before ( Was getting ~710Khash) on my single 280x in the rig before this Im getting around 450 now on one card, and the other is staying as low as 2.4 khash/s Shocked Looking at it now it's on 0.0 khash :| This is the kind of cgminer code i am using export GPU_MAX_ALLOC_PERCENT=100 export GPU_USE_SYNC_OBJECTS=1 COLOR 0A C:\Cgminer\cgminer.exe --scrypt -o stratum+tcp://rbbt.weminecrypto.pw:3333 -u user.username -p password -I 13 -g 2 -w 256 --thread-concurrency 11200 --shaders 2048 --expiry 1 --scan-time 1 --queue 0 --no-submit-stale --auto-fan Please, any ideas what's going on here? Help is greatly appreciated and will be happy to donate some coinage I am using 14.1 betas (as I did before) Seems the drivers are crashing heaps now and cg miner is crashing too :'( Title: Re: Problems adding more cards - r9 280x Post by: Ritual on March 04, 2014, 03:47:15 PM What kind of PSU do you have?
