Even one error is bad.

What kind of problems should I expect with errors like this?

Anything and everything is possible.
App crashes, data corruption, spreadsheet calculations getting the wrong results, visual glitches on the screen, CRC errors, data re-transmission, BSOD, machine fails to boot, or maybe if you get lucky no noticeable effect at all.

Should I test each RAM stick by itself to find the culprit? How many hours should I go? I'm pretty sure that the 5 errors showed up in the first 5 hours with no more errors after that. What kind of problems should I expect with errors like this?

V4 is now a very old version of the software. There was no logging in V4.

Yes, you should be concerned. It looks like the RAM is bad.

I have memtest86-4.3.7, since my computer is old. I just ran a test for 16 hours and got 5 errors, testing all my 8 gigs of RAM. Here's a pic of what it looked like. I then hit ESC, and it started to reboot, I removed my USB and then put it back in right away. I have no log on my USB. Are there logs somewhere on my WIN 10 computer, or is this pic enough. Should I be concerned or is this acceptable?
