unable to mine ravencoin: CUDA_ERROR_OUT_OF_MEMORY

Hello fam,

Need your expertise. Card was mining fine until this morning and t-rex is giving me this error

CUDA_ERROR_OUT_OF_MEMORY

I thought "did the DAG size increase?!" – doesn't look like it.

I tried using different mining software (nbminer, lolminer) and gives the same error.

I have also increased my virtual memory and still giving the same error.

Card that I have is a GTX 1650S 4GB mining on Windows 10.

Card mines fine on ETC but not on ravencoin.

Also tried using older version of T-rex – no go.

Tried using default setting (no OC) – no go.

​

Any insight would be highly appreciated. Thanks in advance!
