Platimum4,
Can you please put the config file used for 290X? I want to mine X11 I read that your Hashrate is 5.4XX .. Is it ok to use the new miner with different pool ?
For what it's worth, I also get slightly over 5.4 Mhash (21.74 across 4 290X's to be precise) with the following X11 configuration:
Engine 1010
Memory 1250
xintensity 360 (I19 would be equal to 186, and I20 would be equal to 372 in xintensity)
powertune 15
worksize 64
I don't have shaders listed but a thread concurrency of 24577.
Threads 1
(I see from the example above that X13 should be able to run with no significant changes in configuration apart from calling out the correct kernel. I'll have to start fresh and give it another go...)
On x13 the hamsi-expand-big setting will apply. If you are on 290/290X please try hamsi-expand-big "1", as the base setting is "4" in the .cl file. Somebody up above was using "7" and has some different results but seem to be less hashrate improvement then it was advertised to be. If you are pulling 5.4M per card on x11 with that sort of config, and I'm pulling 5.46M/5.596M per card with my config, then I may not try and fix what's not broken; I may drop to your clocks to compare if I need to. When I went up to xI:320 (little less than 360) it was blowing my cards into SICK real fast (well, the one continually troubling one) so I haven't gone back to tweak just yet, I restored it to I:19 for stability. My thread concurrency on previous builds was 14080 when it was specified, which was the default given to it by the miner.
Ideally, I may try and knock my powertune down to 15.
EDIT: On the rig with the frequent SICK card I stripped out gpu-powertune entirely, but I still have max avail power draw +50% set in MSI Afterburner. Not sure how I can measure electrical draw until I get my weekly usage sent to me from my energy company. Ever since started mining they knocked me into a high-use "hey we're sending you emails each week so you don't forget your usage" type shit.
EDIT2: Stripped out all gpu-powertunes and no drop in hashrate; barely maybe .002; gonna roll with it for the time being at voltages .9V
