    Hi again. I tested my ram modules as you advised. And here are the test results.
    Hyperx modules, Dram voltage 2.2V, Mch 1.26V Maxxmem results:
    Test1 Test2 Test3
    5607 5562 5607 Memory copy
    5947 5777 5968 Memory read
    4842 4394 4841 Memory write
    83.5 85.5 83.5 Memory Latency
    5.39 5.09 5.31 Gb/sn Reached memory score

    Mushkin Modules, Dram voltage 2.02V, Mch 1.26V:

    Test1 Test2 Test3 Test4
    5164 5595 5601 5595 Memory copy
    5766 5940 5942 5950 Memory read
    4799 4839 4841 4842 Memory write
    87.6 83.6 83.5 83.4 Memory Latency
    5.28 5.30 5.30 5.31 Gb/sn Reached memory score

    Both memory kits (8Gb), Dram voltage 2.16, Mch 1.28V:

    Test1 Test2 Test3 Test4
    5102 5614 5641 5607 Memory copy
    5652 5954 5598 5949 Memory read
    4405 4825 4527 4844 Memory write
    89.7 83.7 89.7 83.7 Memory Latency
    5.03 5.24 5.06 5.24 Gb/sn Reached memory score

    Windows experience index was 7.1 in all of the configs. I really don't understand why they perform badly compared to yours. Any more recommendation? It seems nothing much left to tweak :-|

    I did some research and found out that mean ddr2 read values are around 7-9 Gb/sec. Mine are not even close to those values :(

    About 6300MB/s read that's the maximum I get with 266MHz FSB.
    I don't like the differences in results, mine never differ more than 30-40MB/s from each other, and more than 1ns latency.
    Please chech in task manager there is no process that consume CPU. Processes tab, sort by CPU, system Idle process should be at 99%.
    Were the DIMMs installed in the same slots in all tests or did you test both 1&3 & 2&4 with at least one of the kits?

    I tested all the modules in their respective slots. Mushkins in 1-3, Hyperx in 2-4. Please don't say that I did the test wrong :) I disabled most of the cpu consuming processes and startup apps before testing. If we oc fsb without oc'ing cpu what should I change in BIOS? Any more cooling needed? We couldn't make both kits run @1066 also. So a frequency under 1066 is needed I guess.

    No, the tests are fine, just to make sure both channels behave he same.
    No extra cooling needed we'll try to keep CPU at 2.4GHz max with default voltage, only idle frequency will be a bit higher.
    Lets try 300MHz FSB first. Load optimized defaults, make any changes nesessary like drive boot order than make the following changes in M.I.T:

    Run a few passes memtest86+ before running windows.

    I applied the settings above. 1 pass in memtest. And here is the maxxmem result. Scores improved, seems to be working but latency is still bad. I really don't get how people gets under 70 even 60 ns latencies with their DDR2 rams?? At least my results improved thanks to you guys ;)





    ps: read values still not close to your 266 Mhz maximums

    This is a real mistery.
    Is this with tRD(Static tRead Value) 8 or 7?
    We can try higher FSB, with x7 multi for the CPU, this means it will idle at 2GHz (instead original 1600).
    You may even need to disable C1E and EIST and let it run at 2.4GHz at all time, or instead set VCore manually.

    There is a newer, unofficial, beta BIOS F11i in the BIOS thread (2nd page) dated November 5th 2010, another thing you may consider.

    Ahah if it's a mistery to you guess what it is to me! :D

    Well I'm aware of that bios but I'd like to try it when it becomes available at Gigabyte's download section. The only issue with my current bios is the random error of "Smart command failed" (I'm using an ssd for boot/system volume).

    tRD is 8. If we try higher FSB what will be the speed of memory? I guess 960Mhz is the max we can make the both kits run at together. Idle 2Ghz is not a problem. But I don't know what does disabling C1E and EIST (does it disable idling all together?)

    The BIOS may never make it to GB site, try to search the BIOS thread for the changes that are listed for that BIOS, it may be targeting the smart error.

    I thought 343MHz FSB, x7 CPU Ratio and 2.40B for the memory(DDR-823) with 4-4-4-12 timings, tRD 8-7.
    It is possible to try 3.00A for DDR-1029, but it may not work or be unstable.
    C1E and EIST is power saving features. If Vcore will drop to the level it was at -1600MHz idle the system may become unstable.
    So it's either diabling this features (Advanced BIOS Features), or set Vcore manually to the default value shown in BIOS, try the second first, it will let the multi drop to 6 but not lower the voltage.

    Yes you were right about the beta BIOS; they updated the AHCI rom and smart issue in Sandforce SSD's.
    I'll try the new settings you've thought. And I agree that they won't run @1029, 'cause they didn't run @1066. As for the C1E and EIST, why does CPU gets unstable when we just change the FSB? CPU is running @ its stock speed right? Why'd there be a Vcore drop? Or is it because it'll have to run @2 Ghz at the voltage level it was @1.6Ghz? Hmm I think I get it while asking :) At least I can try, a BSOD or hangup won't harm...

    I couldn't understand this part..

    The second option, set vcore manually to default value shown in BIOS or one tick highr.

    EDIT: those function lower the CPU multiplier and lower thevoltage at idle to save poer. Not sure if the voltage will be enough at 2GHz as it is at 1.6GHz.
