Thread: ? on swapping RAM on a Gigabyte EP45-UD3R rev 1.1

    Default ? on swapping RAM on a Gigabyte EP45-UD3R rev 1.1

    I have 2x2 (4G) kit of OCZ Reaper series RAM. It's PC2-9200/1150Mhz. I have the option to swap out to 2 - 2x2 (total 8G) OCZ Vista Upgrade DDR2 PC2-6400/800Mhz. Both have the timings of CL 5-6-6-18 (CAS-TRCD-TRP-TRAS). The Reaper series has voltage of 2.1 and the Vista series is 1.8v. I have the mb set to 1066 and I know I'll have to drop to 800mhz with the Vista kits.

    Since I'm not doing gaming do you think this is any real loss in performance? I'm running Win7 Pro 64bit with the Intel E8400. It's current clocking at 3.83Ghz but I'm concerned that I will not be able to maintain this speed with the CPU by swapping the memory. I'll get 4G n capacity which may help a little and the swap will not cost me anything. Possibly more stable (things seem fine now) but feel I'm going to take a noticeable hit in performance.

    Feedback would be great. Thanks!

    There is no way to tell if they are stable or work at all untill you try.
    If they do work, there a good chance you can get the CPU to 3.7+GHz so the performance loss is not that bad.
    It all depands what you need the 8GB for.

    I don't NEED it but it's what's being offered as a replacement at no cost to me. I will say that I have seen Win 7 perform a little better when jumping from 4 to 8G when 4G seemed to be ample for my needs. I think Windows just like memory.

    If it works don't fix it, that's my opinion. Memory compatibility issues are always possible.

    I went from 4GB to 8GB on my EP45-UD3P rev 1.1 w/ G. Skill 8800PI and do notice the difference. I would as long as the ram is mobo friendly.
