I have 2 Sapphire 290's that mine perfect at 880khs each on air. BUT
As soon as i add my EK Nickel/Plexi CSQ Clean blocks the cgminer will open say the first line of text and not continue. (Although GPU's are showing under load in GPUZ)
So if it was 1 block then ok people can mess up i could see maybe i had a bad mount but i mounted these cards like 6 times each now and also have 10 other cards on water and have mounted countless numbers of blocks for myself and customers. (So ruling mounting out as a problem at this point)
Here is the part driving me nuts:
As soon as i put the stock coolers on the cards mine perfect again ??
My conclusion is it has to be something to do with the fan being unplugged and cgminer but i cant seem to find anyone else mining a 290 or 290x on water and im hoping so badly someone here knows because i really want to keep my blocks on.
All Games and Benchmarks work Perfect - Only cgminer is effected.
Things i tried already:
Deleted .bin files from cgminer and re ran these commands:
setx GPU_MAX_ALLOC_PERCENT 100
setx GPU_USE_SYNC_OBJECTS 1
Remounted blocks many times and left back plates off for now. (cards always mine with stock coolers)
Reinstalled same driver and Trixx utility which i prefer over Afterburner.
I am using this .bat file which always works perfect on my cards with 1003 Core and 1500Mem :
START C:\cgminer\cgminer.exe --scrypt -o stratum+tcp://earth.vircurpool.com:3333 -u username.5 -p password --thread-concurrency 32765 -I 20 -w 256 -g 1
Tried crossfire and non crossfire mode and am also am in slots 1 and 2 on an MSI Z87 G-45 Gaming Board with 8 gigs of ram.
Tried Plugging the fans in while the cards are on the bench but the wires are to short and my cards are not mounted.
last week i tried just 1 card and had the same problem and even reinstalled windows and it did no good so not bothering this time as i know if i put the stock coolers on they will work.
Between $300. it costs me for Blocks and Back Plates and the money i am losing daily not running these cards i seriously need some help but for 1 i cant even find anyone with a 290 or 290x on water that mines which i cant believe. I really need to get this fixed today before i take the blocks off yet again for good which will be very bad as i got the blocks to run 4 cards on 1 board without risers so i need to blocks working.
Oh yeah also tried --gpu-fan 0 and --gpu-autofan and still nothing.
