Can anyone please help me. I'm only getting 240khs per 290s and i have 4 r9 290s. heres my spec.. and i have 4gb of ram running windows 7 64 bit

setx GPU_MAX_ALLOC_PERCENT 100
setx GPU_USE_SYNC_OBJECTS 1
"C:\Users\Mining Rig 1\Desktop\vertminer-0.5.3\vertminer.exe" -o stratum+tcp://s.ny.vertco.in:3333 -u fafs.1 -p fasfs -I 13 -g 1 -w 512 --lookup-gap 2 --thread-concurrency 8191 --gpu-engine 947 --gpu-memclock 1250 --auto-fan --temp-cutoff 85 --temp-overheat 83 --temp-target 75

I have the same problem first trying yesterday. Today just increase System RAM to 8GB and easily jump to 420Kh/s. But I am not sure 4 GPU need 32GB or not LOL
setx GPU_MAX_ALLOC_PERCENT 200
TC increase to 24000 and OC the VCC with 50mV E 1000 M 1500.

i cant go over 8192 without gpus going OFF. ima try to add 4 more gb
