AMD64x2 Dual Core 5800+
Gigabyte GA-M57SLI-S4 Ver:2 - BIOS version FE
Gigabyte Nvidia GeForce 7600GT 256MB
Kingston KHX6400D2/1G HyperX x2 - total 2G Ram at 800Mhz
Power supply: 550W
And thats my problem: When i first installed the PC (first time i opened it) at boot screen at BIOS i saw that my computer identified my Ram at 667Mhz speed. I read that my motherboard supports 800Mhz DDR2 Rams but my Rams where identified at 667 speed. Then i searched about the voltage needed for my Ram to work properly and about how many volts my motherboard's DDR2 slots give, and i get that numbers: My Rams need 2v to work at full speed(800Mhz) and my motherboard's DDR2 slots give only 1.8v. I also saw that KHX6400D2/1G HyperX work at 667Mhz speed if the voltage of the motherboard is 1.8v. I tried to overvoltage the DDR2 slots to 2v but my Rams still working at 667Mhz. Is there any other option i need to change from my BIOS so i can achieve 800Mhz speed? Thanks in advance.
