Overall, very satisfied so far. However...
I added the Adata XPG Series 8gb kit (model AXDS1600GC4G9-2), and started up a quick MemTest+ scan. In the first pass, if found a single error is Test #4, where one single bit was read incorrectly. I then tested each chip individually in the bottom slot, 3+ passes, no errors. I then installed them in the opposite order from previously (swapped bottom & top stick), and ran overnight. 6+ passes, no errors. Next night, ran again, 6+ passes, no errors. Weird. I'm gonna just cross my fingers and hope for the best.
Anyone else get any weird results from MemTest+ ?
