mixing ram

[hollyh88]

Good afternoon i have a question

 

I have some old memory
https://tweakers.net/pricewatch/1236895/hyperx-predator-rgb-hx432c16pb3ak2-16.html

And its not available anymore thus i need to buy newer ram. and have to decide whether to mix or to buy fully new.
Would it be fine to mix the one above with for example this?
https://tweakers.net/pricewatch/1728578/kingston-fury-beast-rgb-kf432c16bbak2-16.html

i will be using it on my ryzen 3800XT system. and i have heard that in general amd cpus arent too fond of mixed memory. 

would be happy to recieve some input on this. As my knowledge on this topic isnt the best.

Yes it should work, altho i would make sure you use the right slots.

So dual channel works properly. (should be as simple as filling the empty spots).

 

They are the same speed, latency and voltage.

You should be able to run both sets at 3200Mhz and a CL of 16 at 1,35V

 

 

But sometimes you can get unlucky and they just wont work together, you wont know until you try.
(Also 4 sticks of RAM is harder on the memory controller on the CPU then 2 sticks. But a 3800XT should be good enough i'd think).

On my system with an intel CPU, I have two different sets of RAM from two manufacturers. If you match their speeds and timings it should be fine, even on AMD

Yeah on AMD works the same, i have mixxed sets and works fine.
(And yes they surely are a mixxed set altho i bought the identical exact same ram, but thats another discussion)

i already have 2 slots populated with the as mentioned before ram sticks. So if i would buy the other ones they would populate the remaining 2 slots. 

my biggest fear is that they will lead into issues due to as far as ive seen many comments on ryzen and 4 slot mixed ram. 

But according to you i should be fine and just run them together with a-xmp? Im running it on a b450 gaming pro carbon ac. 
or do you think i should contact kingston about it and ask what they think?

It indeed should work.

But my words are not gospel.
I will take no responsibility for this.

If you're really lucky you will be able to run them with XMP.

 

If you have neutral luck they will only work at default speeds.

 

And if you are unlucky they won't work at all.

 

Press Your Luck.

so i have spoken or rather questioned someone at kingston about it. they reckon i should be able to pair it with this model: https://tweakers.net/pricewatch/1729642/kingston-fury-renegade-rgb-kf432c16rbak2-16.html 

 

due  to it being the so to say replacement of my current pair of ram sticks. And according to them is an identical module. 
And the reason my current pair was discontinued is apparently due to the hyperx brand being bought by HP. and thus they needed to replace it. hence the reason why its now called kingston fury and no longer hyper x.
"The KF432C16RBAK2/16 is the module which follows the discontinuation of the HX432C16PB3AK2/16 since the purchase of the HyperX brand name by HP "

so can i trust them and go ahead and mix it or is it still just a matter of being lucky or not?

There is no way to know. Even a matched set of 4 sticks can often not work right.
