    Hi,

    I'm curious if it is possible to use 2666 memory on 2933 with loosened timings.

    thanks in advance

    But I guess you need CPUs that actually support the higher memory frequency?

    @Micro thank you very much.
    I didn't find any affordable dual rank 2933 memory so I went for 2666.
    Now it runs @2933 - 3000MHz depending on OC or not.
    So I get over 250GB/s read and over 160 gb/s write speed as well as superb L3 cache speed

    frequency displays different values but during benchmark values are equal

    Sorry for the late reply, but could someone help me in overclocking my memory? I´m running 2 * Xeon 8167M and 6 Dimm´s of Samsung 2Rx4 16Gb 2400T Registered ECC on the ASUS C621E Sage.

    I went to the Bios, disabled POR and changed memory speed to 2666. Upon saving and restarting, memory still boots as 2400. Am I missing any step? Thank you

    the pc restarts a few times to get the memory configuration.
    I had to increase the dram voltage.
    have you put your dimms according to the manual?

    everything else regarding memory settings is set to stock

    Thank you so much for your answer!

    Yes, the dimms are according to the manual, in the right positions. I will try to bump up the voltage, maybe that will do the trick. If it doesn´t work, I´ll replicate the exact settings you have.

    Best regards
