    Default EP43T-UD3L, E5200, Corsair DD3 - Optimal Settings to get RAM to 1600 MHz

    So I have a new EP43T-UD3L, a E5200, and 2x2GB of Corsair DD3(CMX4GX3M2A1600C9). I understand that in order to get to 1600 MHz for my RAM I have to have the FSB at 400, but nothing I do allows me to boot at that speed, even when lowering the CPU Frequency. Here are my current settings. Hope I did this right.

    These settings run just fine but would really like to take advantage of the RAM I purchased. Thanks in advance!

    AFAIK the E5200 has an FSB wall around 320-360MHz depending on the sample, so your best effort would be to find the highest FSB possible.
    Up to 355MHz FSB (DDR-1420) timings 8-8-8-20 should be possible, then find the lowest possible tRD(Static tRead Value in BIOS) for both channels.
    Keep CPU Ratio at 9 or 8.5 while you experimenting then raise it.

    How are your CPU/core temperatures for this OC? What kind of CPU cooling do you use?

    I was beginning to wonder if it was not the chip. Thank you for the information. When you are talking about keeping the ratio at 9 or 8.5 are you talking about the multiplier?

    Right now 99 degrees F at idle and around 127 degrees at load. I am using a Ximatek HDT-S963 cooler now.

    Thanks again.

    Yes the multiplier, just to avoid instability that is cause by CPU OC, 9 should be fine up to 366GHz since you already running 3.33GHz.
    You may try to increase VTT(CPU Termination) a notch or two and see if it help with higher FSB.

    I assume those were core temperatures?

    Yes, they were taken with CoreTemp and HW MOnitor. There are discrepancies of ± a few degrees between the programs, but those temps are around the average.

    Thanks again for all your help. Another question I had would if it would be advantageous to look at getting a new 775 chip to push towards 1600 MHz, or should I just save my money and go with a new 1156 board and chip and reuse the memory at a later time? I think I may have just answered my own question, but comments or insights from the experts out there would be great.

    Lastly, a lot of the older posts that contain links to templates and such that I would really like to see. However, the links do not work (page cannot be found is the error, not a 404, just that). It looks like the forum changed its formatting for the URLs. I tried pasting the number into the "showthread.php?t=" line but it will not work. Any ideas? I was specifically looking for the profJim posts regarding a set of basic settings to use on a board like this. Thanks again!

    I'd say save the money unless it really burns in your bones, or if you can get E7500 for your E5200 for not too much extra bucks.
    In X-Bit labs article from 2 years ago the E5200 won the best price/performence ratio for C2D.
