I have recently noticed why my performance is running so low...Only half of my RAM s being recognised, i should have realised this when Windows gave my RAM a rather depressing score of 5.5 (pretty poor for supposedly 2x2GB of DDR3 RAM). Here is a small list of evidence for my 'missing' RAM: System: Installed memory (RAM) 4.00 GB (1.99 usable) System Information: Installed Physical Memory (RAM) 4.00 GB Total Physical Memory 1.99 GB Available Physical Memory 908 MB Total Virtual Memory 5.99 GB Available Virtual Memory 4.35 GB Page File Space 4.00 GB Oddly CPUID thinks i have 4096 MB of RAM, Same with DxDiag. Before anyone mentions it, i have tried different combinations of RAM in different Slots and A1, A2, B2 i dont think work. Should i send the motherboard back of are the socket chips bent, i can't decide! NOTE: 64 BIT OS!!!!!!!!!!!!!!!!
