hi guys new to the forum this is my first post,
i have found a thread on this forum that relates to the same issues im having,
https://bitcointalk.org/index.php?topic=360964.0that link is someone else with similar ish hardware but i cant post in that thread
i started mining about 3 months ago and have now built a custom rig to mine with
Corsair Odsidian 900D
Asrock Fatality gaming mobo
Intel Duel Core chip G620T i think,
3x Hd 7990's all malta cores, all 3 now have waterclocks, i fitted only 1 of them and thats the card im having issues with.
Corsair AX1200i
Corsair TX750 Both in use on my board 1200 = 2gpu and mobo 750 = 1 gpu
windows 8 x64
cgminer 3.7.0 and i was using 3.1.0
now for the problem, the one card that i added a waterblock too has started throwing me problems, i mined on it without issue except slightly higher temps than i would have liked mid 80s, however now i have added a water block and now run it constantly untill yesterday.
i should add to this it mined for about a week with the waterblock on i kept an eye on temps no higher than 85c on either core
my system started locking up first this one card was mining slowly no temp rise out of the ordinary, so i just left it for a bit to see if it would speed up, when i next look at the machine it had locked and frozen the picture on the screen the card in question showing something like 500c on the temp scale, everytime it locks it shows me that sort of temp.
troubleshooting steps ive taken,
updates drivers for all video cards (locks up when it gets to the card in question)
updated cgminer
tried bfgminer
run this card on its own from installing drivers to mining locks on both operations
ive tried using this card on my ax 1200 psu as this one card has had its own 750 psu to soak up still no difference, my other 2 cards are fine.
i even had a spare hdd lying around so did a fresh install just to be sure still no go, any help would be much appreciated
