Windows Vista Ultimate 64-Bit 4GB RAM RRS feed

  • Question

  • I have been running 3GB RAM on my system with 64-Bit Vista for quite a while now. I have recently tried to upgrade from 3GB to 4GB RAM.


    PC Specs:


    Intel C2Q q6600 @ 2.4

    250GB WDC HD

    XFX nForce 680i LT SLi Mobo

    eVGA 8800GT SC

    3GB OCZ SLI-Ready RAM ( 3x 1024 MB)


    After inserting the fourth DIMM into the remaining RAM slot and powering on the computer, the monitor doesn't kick on. I get no POST or ANY boot screens. The monitor remains inactive until powering off the system. The system works fine with 3 GB RAM, but I have had no luck getting it to run with 4GB. I had a similar problem when I was running 2GB RAM before. I accidently installed the sticks into slots 0 and 2 on the motherboard and the monitor didn't kick on. I simply moved the second stick to slot 1, and it worked fine. However, there is no option for rearrangement seeing as how I'm using all 4 slots when trying to use 4GB RAM.


    Is there certain BIOS requirements and/or settings I should be using in order for the system to run with 4GB RAM? Any help or suggestions would be appreciated.

    if your ram runs at 800 mhz try to lower it to 667 mhz. Don't known about your ram, but i have corsair 4*1024 and at ramguy i found topic, that if you wanna runt 4 gb in 4 dimm you have to decrease it to 667 mhz. That helps me.
