Edit:
I moved the intensity to 19 and it gives a stable hash of 423. At 20, it still works but pc starts to lag and I can't do anything else

Updated:

With Sapphire R9 290x BF ed, I'm using the below to get stable 436 KH with zero hardware error. Any other setting and tons of HW errors start coming in. I think the thread concurrency did it for me. Has to be 2816*8 for this card. Don't ask me why (though I'm a computer engineer; just not very upto speed with AMD chipset). Also I run the fan at fixed speed of 75% from Trixx to keep temperature below 75C.

setx GPU_MAX_ALLOC_PERCENT=100
setx GPU_USE_SYNC_OBJECTS=1
COLOR 0A

vertminer.exe --scrypt-vert -o -u -p -I 20 --lookup-gap 2 -w 256 --gpu-engine 1000 --gpu-memclock 1500 --thread-concurrency 22528

I'm running these same settings, but also trying to mine with an A10-7850K at the same time, and vertminer gives me a black screen. It starts up, it mines, but the UI is not there. I am also running The Stilt's improved Litecoin BIOS for my Radeon R9 290X.

Here's my bat file.

Code:

setx GPU_MAX_ALLOC_PERCENT 100
setx GPU_USE_SYNC_OBJECTS 1
COLOR 0A
vertminer.exe --scrypt-vert -o -u -p -I 19,11 --lookup-gap 2 -g 1 -w 256 -d 1,0 --thread-concurrency 22528,5120

I'm gonna try running without the iGPU for now, which allows me to see the UI.

Whenever I try a bat file enabling only one GPU, whether I do -d 1 or -d 0, it chooses the iGPU, effectively keeping me from hashing with only the R9 290X.
