Hi Everyone,
I have about 3 rigs, never ran into this problem.
Specs: MSI 270a Pro Mobo 8 gb ram 6x MSI Nvidia 1060 1000W PSU (another rig runs this, its plenty) Risers
Running claymore (genoil doesn't work well on my rigs for some reason, slow text)
I flashed the BIOS to have the cryptocurrency mining setting on. I've tried installing windows with that setting disabled, only using one card, and running through all the driver installations. Then circling back around and turning on the bios settings (crypto enabled, gen 1, 96 latency etc.) I've tried leaving it on auto, I've tried gen 2. I've disabled and renenabled about every setting. I swapped out power supplies, changed out the motherboard (From a MSI 270 SLI to a 270A pro). I don't suspect the risers because I had it working for a brief period, then the miner hit this error and was never able to run it at 6 cards again. I'm using the same start.bat that all my other miners use.
Specifically, the miner is saying:
GPU X, GpuMiner cu_kd failed 77 (0), an illegal memory access was encountered GPU X, Calc DAG failed!
For every GFX card, where X is the GFX card number.
I've also tried turning off the cryptocurrency setting, and it seems to help sometimes, sometimes not. At one point I was able to get back up to 4 cards by turning this setting off, but after reformatting and reinstalling windows to try to get a clean install on drivers countless times, that has since passed.
I've also reset CMOS, etc.
Any help? I can't find much documentation on fixing error 77...is this a MOBO issue?
Thanks
