Memory issue on my 4GB 1050Ti #264

When I try to run the miner I get:

GPU 0, GpuMiner cu_kd failed 77 (31), an illegal memory access was encountered

‘GPU 0, Calc DAG failed! ETH: 07/14/18-22:31:11 - New job from us1.ethermine.org:4444 ETH - Total Speed: 0.000 Mh/s, Total Shares: 0, Rejected: 0, Time: 00:00 ETH: GPU0 0.000 Mh/s GPU 0 failed Setting DAG epoch #198 for GPU0 Create GPU buffer for GPU0 CUDA error - cannot allocate big buffer for DAG. Check readme.txt for possible solutions. GPU 0 failed WATCHDOG: GPU error, you need to restart miner :( ‘

Worked totally fine before a couple months before now, using Ubuntu 17.10 & GTX 1050 Ti (4GB).

Same issue accept Windows 10 Pro 64-bit. What I tried:

Tested cards individually ended up being the 1050 ti 4GB EVGA & not my ATI. downloaded fresh copy of dual miner. - No change reinstalled video card drivers. - No change Adjusted virtual memory - No change Tried on another computer - No change

Card had memory errors on some diagnostic software packs however since it's passing EVGA's diagnostics I can not warranty it. Was working fine less than a week ago.

I have an EVGA card too, curious if this issue affects other use cases like gaming. If not, I could sell the card and buy a new one.

So after much testing between systems I got mine working again by using the latest version of claymore dual miner and the latest Nvidia driver. I basically started everything from scratch & it worked. I believe the thing that helped the most was removing all Nvidia and ATI drivers from the machine/OS. It appears that the memory issues were due to windows or a driver conflict. When I scanned the video card memory outside Windows it came up PASS every time.
