In a pickle

I built my system not long ago and at the time I could only afford 8gb of ram I chose 2x4 Kingston hyper x 2133 it's very good ram and can easily oc to 2400 with xmp. I'm ready to stick another 8gb in there. Should I buy the exact 2133 or bump up to the 2400 which actually a few bucks cheaper? Will I cause any instability?
System specs:
Asrock ab350 pro
Ryzen 1600 oc to 3.75 stock cooler
Gtx 1060 6gb
Cosiar tx 550 psu
Or for the same money get and aio cooler?

  1. never mix and match ram. buy the exact same stuff you have now and try to oc. (not that I like the idea of buying 2 packs of the same type of ram all that much either, its far better then mix&match).

  2. 1. Buying extra ram is not guaranteed to work.
    Ram is sold in kits for a reason.
    A motherboard must manage all the ram using the same specs of voltage, cas and speed.
    Ram from the same vendor and part number can be made up of differing manufacturing components over time.
    Some motherboards, particularly AMD can be very sensitive to this.
    This is more difficult when 4 sticks are involved.
    That is why ram vendors will NOT support ram that is not bought in one kit.
    You have to ask yourself... What is my plan be if the extra 8gb does not work?
    Will you return it or what?
    My suggestion is to buy a 2 x 8gb kit that is compatible and closely matches what you have.
    Buy a kit that the Kingston ram selection app says is compatible with your motherboard.
    Then see if your old kit works in concert. If it does, you have 24gb.
    If it does not, keep the old as a spare or sell it.

    2. To my mind a aio cooler is not a good thing if you have a case with 160mm cooler headroom.
    I recommend the scythe kotetsu @$35.

    Save your money for something more effective.
    My canned rant on liquid cooling:
    ------------------------start of rant-------------------
    You buy a liquid cooler to be able to extract an extra multiplier or two out of your OC.
    How much do you really need?
    I do not much like all in one liquid coolers when a good air cooler like a Noctua or phanteks can do the job just as well.
    A liquid cooler will be expensive, noisy, less reliable, and will not cool any better
    in a well ventilated case.
    Liquid cooling is really air cooling, it just puts the heat exchange in a different place.
    The orientation of the radiator will cause a problem.
    If you orient it to take in cool air from the outside, you will cool the cpu better, but the hot air then circulates inside the case heating up the graphics card and motherboard.
    If you orient it to exhaust(which I think is better) , then your cpu cooling will be less effective because it uses pre heated case air.
    And... I have read too many tales of woe when a liquid cooler leaks.
    google "H100 leak"
    I would support an AIO cooler only in a space restricted case.

    Your pc will be quieter, more reliable, and will be cooled equally well with a decent air cooler.
