Hi Pallas
thanks for the work you've done. ive run my rig pointed at your address while setting up my miner, and will do so some more once i get
things running ok.

Currently im struggling to get my sapphire r9 290 over 850kh
i also have a dual x r9 280x in the same rig which is getting 1016kh

i originally tried the r9 290 on its own and was getting 1300kh and read at the begining of your post speeds of around 1700 for a r9290
so i upgraded to 14.12
i also introduced the r9280x and then made 2 bat files so i could run 2 instances of sgminer.
Now im only getting 800+kh on the r9290. and its hit and miss as to whether i get HW errors. sometimes i do sometimes i dont (even with the same settings)
I wonder if you can enlighten me as to what i am doing wrong?

I am using amd 14.12 omega, sgminer lyra2re win.

here are my bat files for the 2 cards

r9290 bat file


setx GPU_FORCE_64BIT_PTR 0

setx GPU_MAX_HEAP_SIZE 100

setx GPU_USE_SYNC_OBJECTS 1

setx GPU_MAX_ALLOC_PERCENT 100

sgminer.exe -d 1 --remove-disabled --kernel Lyra2RE -o stratum+tcp://eu.p2pool.pl:9171 -u VsLK3LaqdGijDVq6HSGbSWfQJhtzFGSBKr -p x --no-extranonce --no-submit-stale --expiry 1 --scan-time 1 --queue 0 -I 19 -w 128 -g 2 --gpu-memclock 1500 --gpu-engine 1000

ive tried intensity 15,17,19 all give me similar hash. same with memclock and engine 835,1500 980,1500 1000,1500 980,1250 all give me similar hashrate

r9280x bat file

p.s. currently im not getting any HW but the last time it ran ok, when i re-booted i got HW. stopped mining, left the pc running for a while then started mining with no HW errors.
