    Default DDR3 2x4GB 2000 MHz Sector 5 on Z68 chipset - help needed

    Hi. How do I set up Sector 5 on Asus P8Z68-V LX mainboard? I know 2000MHz is not good for Sandy Bridge. Currently it's running as 1033MHz. I tried 1866MHz 9-11-9-27 1.65v but without success. Any ideas?

    Thanks!

    Hello,

    Try flashing the motherboard to the latest bios.

    In addition to dram voltage at 1.65v, set cpu core voltage to 1.40v, vsa or system agent voltage to 1.40v.

    Are you using the native Baseclock and changing only the memory speed to DDR-1866?

    Let me know if this helps. Unfortunately you may have to relax the timings and/or frequency; ie; 1600MHz, 8-9-8. What we found was that memory speeds may not necessarily correlate from (memory tested on) the P55 to the Z68 platforms.

    I have the latest bios already.
    I'm changing only the mem speed. 1866MHz won't work but fortunately 1600Mhz does - that's something
    Is it safe try overclocking to 2133 or better leave it alone?

    I have found manually setting the voltage to 1.65 volts first and then selecting the memory frequencies and timings you want on second boot often has the best success on these platforms. You can try using the XMP profile which may or may not work for you. Otherwise, set it all manually. Keep in mind that you are consequently overclocking the CPU's memory controller, so a bit of patience is required. Let us know how it goes.

    You can try 2133MHz, but it might not work since it's only been tested at 2000MHz (especially if 1866MHz wouldn't work). Your best bet would be to keep it at 1600MHz and trying tweak the latencies. Good Luck!
