Hi all - new creating forums, that’s just how desperate i am!
TB250 biostar BTC+
2x GTX1080ti Gaming X
1x GTC1080ti armour OC
1600 watt PSU
128 gb SSD
USB risers for all GPUS
been mining Z cash easily with 2 GPU’s (gaming x and armor OC) getting good results and running super stable mining z cash with ewbf 0.34b for about 2 months. problems came when i bought a third GPU (another Gaming X)
the 3rd card makes the entire rig super unstable, it is detected in geforce experience and device manager.
-when i open nicehash/ewbf my graphics drivers crash and recover but then my computer only registers 2 of the cards and then i am able to mine, usually graphics drivers crash then i get a windows prompt then nothing works(sometimes mines zcash for 15-30 seconds before crashing)
-sometime when i reboot it doesnt even detect all three GPU’s, it detects them when it wants to
-i can mine LBRY using all three cards and runs the miner well but is still feels unstable (havent ran for more than 10 minutes)
what ive tried:
-reinstalled the drivers a thousand times- done clean installs, done reinstalls, completely deleted and reinstalled all GPU software.
-moved cards around to different PCIe slots and with different rizers/slot combinations
-formatted the hard drive and did a complete reinstall/setup of the Rig’s software
-changing clock speeds - dont think power is the problem
