The issue is I need more speed for fewer frame drops when streaming HTPC stuff.
This PC was my fastest with 8gb memory (and the Win10/32) and totally shamed my 100% reliable/robust Windows Media Play AMD X2 VISTA box I replaced.
However, in a relatively short time, it started slowing down. Couldn't find any real issue other than Firefox needing all available memory which appears to be a JAVA issue.
NOTE: ClamWin found 4 viruses that it could not move or delete probably because they were in use by Windows? AVE and Malwarebytes found nothing although neither do a full directory scan like Clam does. I know this is a separate issue but probably relevant to the slowing down issue. I've installed add-ins to detect bit mining at web sites and have never encountered any.
So I want to take advantage of the 16gb.
I do know that 8gb @ 64 bit is equivalent to 4gb @ 32bit, so the 16gb @ 64 is definitely not an excessive amount of memory.
