    Default Help with GA-EP45-DS3R and OCZ Reaper 8500

    alright, first I'll give you my computer specs:


    • Motherboard and revision: Gigabyte GA-EP45-DS3R v1.0
    • BIOS: F10
    • CPU: Intel C2D Q6600 @ 2.4GHz
    • Memory: 8GB OCZ Reaper HPC OCZ2RPR10664GK (I have 2 4GB kits)
    • Video Card: Saphire HD4870 1GB
    • Power Supply: Cooler Master 750W
    • HDD: 3x WD 500GB (No Raid)
    • Optical Drives: LG SATA DVD+/-R
    • Operating System: Vista Ultimate 64bit

    I'm trying to get the system stable at 3.6GHz, but memtest tests 5 & 7 fail. Actually test 5 locks the system around ~52% of the first pass.

    So here are the settings I'm currently using:

    Ok, I made the changes you recomended and I get a rebooted from memtest during the first pass. I get a stable system at a x8 CPU multiplier giving me 3.2Ghz so I have hope. I'll play with the range values somemore and see if I can make it work.

    Ok, no joy with those values. Either memtest locks up or it reboots after about 28%.

    What is your exact settings that fail with two sticks? Sorry to ask likely again, but have you tested each stick one by one at stock?

    I can get them to run fine at stock just not at 3.6GHz I'm doing some more testing today and I'll let you know what I find. Thanks so much for the help also :)
