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.

Hi Bill,

 

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.

 

Cheers,

Peter

Hi Peter,

how much physical memory does your PC have?
