Now i use 2GB DDR2 667 MHZ under Windows 7.
Later,I have bought a new one 2GB DDR2 800 MHZ..
But,the new ram seem smaller than the old ram..About half of size than the old one..
Then,When i put the new one together,it cannot BOOT as usually..The red led light on my cpu..
What Should i do???
AMD Athlon 64x2
ATI Radeon HD 4650 1Gb
