    That was the point of my post #6. UMA on an AMD board assigns a certain amount of ram to graphics exclusively. It is therefore not available to the OS. WEI penalizes you for the reduced amount of ram. Glad you got it fixed right.

    Open a cmd promyt as admin and do:
    winsat mem

    Itll give a idea of what the actuall bandwidth is. If its close to what it should be, dont worry.
    If its extremly low, theres something wrong.

    The WEI scores themselves rteally don't give much to go by.

    As another suggestion, try an actual benchmark and see how the system is running. WEI should be used once to ensure Aero is enabled, and that's it. It serves no other purpose, is horribly unreliable, and can be edited to show whatever score you'd like. Putting any thought or effort into it is just a waste.

    Thanks Guys (Yet Again)


    Thanks (yet again) to everyone for your input/suggestions.

    Here is a screenshot of the cmd prompt output:

    Here is a link to the product info (F3-10600CL9-2GBNT):
    G.SKILL-Products

    How do I relate the 2 bits of info?
    I read a review on the more expensive version of my MB (ASRock 880GMH - I have the LE version).
    The reviewer's test result was ~12.5 GB/s, so I guess mine is performing pretty well. :)

    The weird thing is that my NVIDIA graphics card performance dropped slightly (WEI 4.5 to 4.3).
    This isn't a problem as I don't play any modern games.

    Thanks to everyone (once again).

    It looks like a $1 capacitor disabled my previous MB.
    It should be easy enough to repair.

    AMDs sometimes tend to have slightly higher Memory bandwith at a given speed Vs a Intel setup.
    His lower results could be due to Memory settings in the bios. Many possible reasons for it.


    Those results look fine to me. I wouldn't worry to much about it TBH.

    Although as DeaconFrost suggested, a actual Memory Benchmark will give you much more accurate, and more detailed results. if this is something you are interested in.

    The windows one is more of a ballpark figure, but usually pretty close.

    AMDs certainly do not have higher bandwidth. A Nehalem or Sandy Bridge will destroy any AMD in bandwidth.

    Benchmark Programs


    Just out of interest, which benchmark programs do people recommend?

    That is ridiculous, First, the Amd cpu comes with memory controller integrated into CPU to lower the cost of manfunaturing, Second, Amd CPU has be to tweaked to go higher clock frequencies to take advantage of more memory bandwidth.

    You're a little out-of-date as regards Intel. The Nehalem and Sandy Bridge CPUs have integrated memory controllers, similar to what AMD has been doing for years. Synthetic benchmarks (such as Core i5 2500K and Core i7 2600K review) show that the high-end Intel CPUs have better memory performance than AMD's finest. I doubt that the real-world differences are that large.

    The price/performance trade is more complex. Most of the budget gaming system guides I've seen in the past year or so use AMD CPUs.

    You can overclock the Northbridge and use high frequency RAM all you want on an AMD system. The truth is that it simply doesn't affect memory bandwidth to any notable degree. Even Thuban, the six-core K10 model, doesn't see any real benefit from RAM above DDR3 1333. Sandy Bridge similarly sees minimal gains from anything above 1333.
