I'm having this problem with my computer's memory:
Memory: CORSAIR 4GB DDR2 XMS2 PC6400 800MHZ (2X2GB)
BIOS registers the memory as PC5300 when I use the MB's (Asus P5WD2 Premium) default settings and it recognizes 4096MB. When I overclock the processor (no matter what speed) BIOS will only recognize the memory as PC3200 but still at 4096MB.
When Windows is loaded (Win Xp SP3, Vista SP1 or Win7 - I use cassettes with different HDD's to boot from) the O/S only recognizes 3071MB of memory.
How do I:
1. "Convince" BIOS that it REALLY is PC6400 that should be running in 800MHz - overclocked processor or not
2. Get Windows to recognize the full 4096MB's
