  • XMP setting higher voltages than recommended?

    Hi guys, recently I bought a set of Trident Z 2x4Gb 3200MHz (F4-3200C16D-8GTZ).

    When I turn on the XMP profile, the Bios displays DDR VOLTAGE: 1.376v, when the one indicated by the label is 1.35v (out of the box, running at 2133MHz, that voltage is 1.216v, the same that the VCore).

    Further details:
    - I've passed Memtest86+ with all the setups and got no errors.
    - If I try to set ram voltage to 1.35v manually, after a reboot the Bios displays 1.360v.
    - My PC, built a week ago: Z170A Tomahawk AC + I5 6600k + Hyper 212 Evo + MSI GTX 1060 ARMOR OC + Seasonic m12II evo 620w + 2x4gb Trident Z 3200Mhz + WD Blue 1TB (planning on adding another set of 2x4Gb of RAM, same model)

    As a noob, my question is: Is this higher voltage okay? I have to set anything else besides turning XMP on?


    Thanks in advance :-)

    The XMP voltage is programmed to 1.35V, but most mainboards slightly overvoltage Vdimm for general compatibility reasons. That slight increase of +10 or +25mV is not really a big deal for the modules itself, because their PCB and the ICs used on them are usually rated for a lot more (and that gets exploited by overclockers world wide).

      Thanks for the reply!

      I thought my memories had some kind of problem, glad to see it's okay
