Just built my first PC and everything seems to be going well. Installed drivers, etc. and am now running Memtest86+ to check the memory. On the first pass it had 1 error, but that has not shown up on the second pass. Should I be worried about this? I've read a lot about people getting either a lot of errors or none. Should I RMA my RAM or was it maybe a false positive? I'll keep running Memtest86+ and try the Windows Memory Diagnostic tool as well. Thanks for all your help.
