  • DDR3 PC10666 CL7 4GB (PI) - Gigabyte EP45T-DS3R

    I purchased a 4GB kit of memory that is labeled as "PC-10600 CL7 4GB 7-7-7-18 @ 1.65v" on the modules and "PC-10600 CL7 4GB 8-8-8-21 @ 1.65v" on the box sticker. To make matters even more confusing though, Everest and Gigabyte EasyTune both report the modules as "PC-10666 CL7" modules.

    My specs are as follows:

    CPU - Intel C2D E8400
    Motherboard - Gigabyte EP45T-DS3R
    PSU - Corsair HX520

    Assuming that the stickers are wrong and it is indeed PC-10666, I have a few questions:

    1. What is the difference between PC-10600 and PC-10666?
    2. If it is indeed PC-10666, is it still compatible with my motherboard?
    3. In my motherboard BIOS, what settings should I be using in order to run these modules at their stock settings? (7-7-7-18)? The BIOS is a touch confusing, however the manual setting for the DDR3 voltage doesn't have a 1.65v option, only 1.64 and 1.66. If I set it to 7-7-7-18 @ 1.7v should I be okay? There is a bunch of other settings like "Performance Enhance" (Standard/Turbo/Extreme), "XTreme Memory Profile" (Disabled/Profile1), "Memory Frequency" and "MCH Frequency Latch".

    Any advice would be appreciated. I am not interested in overclocking at this point, just merely having the memory running stably at the factory settings I purchased it for (7-7-7-18).

    Thanks!

    1. PC3-10600 and PC3-10666 are the same, the difference is only the word "10600" and "10666"
    'coz some country would like 10600 instead of 10666, so we have different model name
    but the SPD value are the same "10666"
    2. no matter 10666 or 10600, they are all compatible with your motherboard
    3. set DDR3 1333 7-7-7-18-2T@1.65v, it is our guaranteed spec
    and if you are running with 4 sticks, please try to add MCH voltage to 1.4v
    thanks

      Thank you for your reply, you have cleared up most of my issues, except I am still not certain on what to do regarding voltage. You say to set it to 1.65v and I understand that, but this motherboard bios doesn't seem to have an option to set 1.65v. It only has options for 1.64v or 1.66v. What would be your suggestion? I notice you have tested the CL9D memory in this exact same motherboard, is it possible you could test it and post a BIOS screenshot of your settings?

      Thanks in advance
