Can I mismatch these ddr3 ram?

[Arty_ily]

Hey guys!

I'm going to upgrade my ram in my PC and I found a good deal used (2pairs, different modells)but not sure if it would work together okay. (disclaimer: fossil era pc)
MB: ASRock Z97pro3
The new ram that I'm not sure about: HyperX SAVAGE HX324C11SRK2/8,

HyperX PREDATOR KHX24C11T2K2/8X

Would these 2 pairs work together just fine at 2400MHz?

EDIT:  I've found these: hyperX FURY HX318C10FBK2/8  its a full 4x8gb kit but it's 1600MHz, so the second question is should I buy these, or risk the higher speed ram with the mismatch? How much difference is there between 1600 and 2400MHz?

You might need some finetuning to get a stable 2400, but it should be fine.

 

Hearing Z97 described as "fossil era" makes me feel way too old.

Yes, the different ram sticks should  work just fine as long as you have them on the same timings, correct slots in the motherboard. Just know that mixing ram kits can lead to unexpected issues in your build. If you have any issues, just update BIOS and you should be fine.

Might be able to, just gotta try! The best chance if all 4 sticks has same memory and PCB layout. (sadly not easy to check before you plug em in to look in CPU-Z and layout is even harder unless you know what to look for)

It's just starting to fossilize don't worry!:)

Would it be easier to run it at 2133 maybe? (also I've edited the original post, now I have even more questions:D)

What kind of unexpected issues?

Would it be more wise to buy a 1600mhz fully matching kit?

So if it's same memory layout it is gonna work fine without any hassle if I'm getting it right?
But if it's not then is it salvageable or I have to replace one of the pairs with a matching one?

I'm looking at Kingston's  datasheets of the 2 rams but thb It doesn't really make sense to me

It's going to boil down to either it works or it doesn't, setup the way you are wanting it to be.

There is a possibility of different sticks from different sets/set models with different IMC's not playing well together (Not compatable with each other), that's is a "Thing" but normally it's not a big issue to worry about.
Also, if these sticks are spec'ed for two different speeds ALL sticks in the system will only run at the speed of the slowest stick(s) - No way around it.

Best advice:
Have all RAM settings in the BIOS set for "Auto" and see if it boots or not.
If it does, then you can mess around with settings from there to see what you finally get. If doing that results in crashing/BSOD's and the like, leave it all on "Auto" and be done with it do the system will work at least.

So i might be better of buying the matching kit which is 1600MHz because if the mismatches sticks don't like each other I'm gonna end off with a even slower ram than the cheaper matched ram? And is it even worth risking it over the that much performance? (Idk how much is difference between 1600MHz and 2400Mhz in performance)

The matched set can always be overclocked past 1600 and is more or less guaranteed to all work together.

 

Sometimes RAM doesn't like when you mix and match, although I've not experienced that in a meaningful way personally. Generally you should be fine if you just put your RAM settings on Auto in the BIOS and slap the new stuff in.

Symptoms of incompatabiliy can range from slower speeds, weird behaviour, crashing/BSOD's to the system just not working at all.

As said, normally it's not a problem if speaking of the machine working or not period BUT, even if it does work you can't 100% rule out all the rest of these symptoms being a possibility.

I'd get a matching set(s) of sticks to eliminate that risk.

DDR3 running at 1200/2400 takes a highly binned set of DDR3 just to get there and I know your setup should be capable by the specs of the rest but also know there is no guarantee of anything to that end, aside from it's/their stock specs anyway meaning the "Bin" of the sticks you get has to be good enough in the first place.

That's why I say "DDR3 running at 1200/2400 takes a highly binned set of DDR3 just to get there" and that's true, I do have a few sets binned for those speeds and they will do it too.

You won't see alot of difference (Except in certain benchmarks) between sets of PC1600 or PC2400 - Even PC2800 sets to make it worth going for on average.
If you find a highly binned set(s) that cheap - Go for it.
Otherwise 1600 is just fine and will get the job done.

No, it’s either going to work or it isn’t. Just try it and if there any issues that you can’t get around then you can consider a 1600mhz kit.

Thanks for the help! Gonna buy the matching kit which turns out is actually 1866:)

Been a pleasure, and thanks again for the information!

A set or matching sets of 1866 sticks should do well in your system.
