4G is a good amount of memory for W7. For W10, its barely enough. I have 16g Win10 machines. One of them may have 32G. I’ve never tried more than one instance of WSJTx though. I usually have Outlook, Excel, Word, Chrome and three instances of Putty open while WSJTX decodes.

Both of them have 4Gb. One is Win7 the other Win10.
I did another test today with 3 instances on the Win10 machine and the processor utilization never went over 60%, but it still stopped decoding.
