I have the TWIN2X2048-6400C4* XMS2-6400 2048MB 4-4-4-12 2X240 DIMM Black XMS2 and the bandwidth test on sandra is giving me really bad results. at 690Mhz 4-4-4-12 @ 2.1v I'm getting 6100Mb/s how does this seem to you. I,ve tried running them at a little higher than 800Mhz somewhere around 20-30Mhz more and I can't ge them stable. Also what bandwidth should I be getting with this kit on the p35. Thanks for any advice you can give.
