    Motherboard code 55

    I just finished putting everything together and when I turned it on, the LED display on the mobo reads 55. What's wrong?

    On my M5F the manual says code 55 is "no memory installed"

    try booting with single channel first, then apply RAM settings, then reboot, check, shut-down and insert the second one.

    usually happens with some crappy RAM or if you change from certain IC to IC (e.g. Hynix CFR --> PSC = "55" always...)

    Something with the sub-timings on mem-reset imo...

    Reseating the RAM fixed it.
