Re: CUDA error 11-cannot write buffer for DAG

Hello,

I had the same problem with CUDA error - cannot allocate big buffer for DAG. Check readme.txt for possible solutions. after upgrade nvidia drivers (7 x GTX 1060 6GB) and Claymore's 11.7.

I try lbr tip but this solved problem only in half way couse trully Claymore's run OK but I had some msg from OS that is a problem with my virtual memory and the OS must shutdown Claymore's... (No matter if I changed setting for virtual memory or not)

ppl say, that only W10(not W10 per ce but WDDM 2.x) has this limitation(reserved and unusable vRAM). So prly W8.1 will work.
Also we checked and 8x1060 work fine on W7.
But you have to to this - https://devtalk.nvidia.com/default/topic/738070/cuda-setup-and-installation/8x-gpu-gtx-issue-under-windows/

However, for some reason DualMiner was crashing with 8xGPU. Two instances worked tho.

Also Quadro/Tesla owners can use TCC mode.

After that I restored a whole system image and do some tests and... everything works fine. At now my rig works on this settings without DAG or virtual memory problem:

Win10 x64
Claymore's 11.7
nvidia drivers 385.69
OS auto update option is disabled

BTW: thare are new driver on nvidia support Official Nvidia GeForce Game Ready 397.55 Hotfix http://nvidia.custhelp.com/app/answers/detail/a_id/4661 but I tested it and they still have a problem with DAG and Virtual memory.

I think that is a problem with new nvidia drivers and CUDA, so we must wait for some fix and new version of drivers.
