LZ1GJD - Which BIOS are you using? I actually have the same issue with PC Mark with my OCZ Plat Rev 2 @1T, but I think that was only when I overclocked. Since I am using the Beta BIOS, I wasn't sure if that was related or if it was common with previous BIOS versions, but it's not something to get too too excited about unless you experience problems elsewhere. Since I experienced random restarts when I performed different operations, I went back to 2T, but the issue could have been that my processor was overclocked too hard (2400Mhz from 2000Mhz stock). That's just me.
If you experience no random restarts, and everything seems stable, then you probably are ok at 1T. If you do a Google search for this, you'll find that many others have problems with the same memory tests at 1T in PCMark, and the conclusion is that there is most likely something wrong with PCMark.
