    Good evening everybody, this one got me puzzled, so I tried to see if my RAM is any good for OC'ing and started with just bumping the clock to 1866Mhz, and indeed it works fine, left the laptop running a couple loops of memtest86 and it never gave a single error.

    Used the laptop a bit more, ran some benches(scoring 720 on CB R15 with a non OC'ed 4720HQ) and it did help with the FPS's in games.

    BUT, if I reboot or cold boot the laptop, the RAM reverts to using the SPD profile, I tweaked the values a bit, but its not instability its that at cold or restart the BIOS re-sets the RAM to using a stock profile instead of using my custom one.

    Any ideas why this happens?

    Best regards.

    No idea,

    but if you find a good OC then record them, you could try rewriting the SPD with the overclock values so it reverts to that instead?

    I think R/WEverything is used for that sometimes but Im not sure how its done.

    is mem training ,,all in SA domain ,,but any oc no need .,cpu versus oc mem not full usable this
    use msr fast boot ,.this disable training or manual training value

    Its related to training, thats a given, because at a cold boot after I do the RAM OC it takes longer to boot.

    If I go too far in any value it blinks the right side of the keyboard read a couple times, then resets the timings and boots with a stock profile.

    @TheReciever I have thought about that, and I know about thyphoon burner, its the last resort, and I would prefer to had a XMP profile than to edit one of the JEDEC ones.

    My RAM doesn't have XMP profiles, only the JEDEC ones, but I tried with a custom profile just to see for myself how much RAM speed impacts CPU performance, and was surprised by how much it does, given that with 1600Mhz RAM I score around 670-680 points on CB R15, 720 points is i7-7700HQ territory.
