Solved Corsair XMS2 1066 Mhz Running @ 245 Mhz Tags: Memory Corsair Last response: December 8, 2012 2:47 PM in Memory Share Edszx December 1, 2012 2:12:43 PM Well i think this is a very simple and basic question, this is my pc: S.O: Win7 x64 SP1 CPU: AMD Athlon 64 X2 4200+ @ 2.2 Mhz (No OC) GPU: Geforce 8400 Gs 512 Mb DDR2 @ 559/1489/309 RAM: Corsair XMS2 1066 (Version 4.1) (2x2 GB) MOBO: ALiveNF6P-VSTA HDD: Western Digital Caviar Blue 80 GB Optical Drive: Sony AD-7240S Audio: Sound Blaster Audigy SE @ X-FI Xtreme Audio My MOBO only supports DDR2 800 memory, but im using these 1066 corsair ones and they work. The problem is that they underclock to 245 Mhz!! I dont know if my CPU is the reason, maybe, but i suppose i can make the clocks go a little high (667 at least). Can someone help me to know if i can OC them or leave them as this?
