    Default How to set the BIOS to work with 8GB @ 1066MHz?

    Hi there.
    I have GA-EX38-DS4 MB and I use 8GB= 4 slots x 2GB sticks RAM of G.SKill
    ‎ F2-8500CL5D-4GBPI-B‎
    ‎ 5-5-5-15 ‎
    ‎ DDR2-1066 (PC2-8500) ‎
    ‎ 2.0 ~ 2.1 Volts ‎

    I use Intel E8500 3.16Ghz @ 3.80Ghz.

    I want to set the RAM to work at 1066MHz and keep CPU at 3.80GHz.

    What are the recommended settings for timings and voltages?

    You may not be able to easily get 8GB working at 1066

    Can you give us a link to your memory

    it's this heat case: G.skill pi black ddr2 800

    but PC8500

    I need a link to it at G.Skill or the store you purchased from, but just to check the voltages which you can show with SPD Tab of CPU-z if you want.

    Above settings should be good for you to use

    Yes that is correct, you may need to tinker a little bit to get going, or you may need to use a slower memory speed with 8GB

    I was able to get 1066Mhz without raising voltages except for DDR2 voltage and ran 10 tests with latest version of MEMtest+ 86 with no errors. Do you recommend on another software for memory testing?

    Sounds good so far!

    Yes, I use HCI Design memtest, 3-4 instances at once with 600-800MB within windows, you can get it here
    MemTest: RAM reliability tester for Windows

    And of course you should also run Prime95 or LinX to test CPU and ram together
