Hello

I have a 6 years old PC build with motherboard - AsRock X370 Killer Sli:
https://www.asrock.com/mb/AMD/X370 Killer SLI/#Support

Currently im running Win7 but will in few days make a new instal with Windows 10. Currently its with Ryzen 1700 CPU in it. In few weeks im planning to (probably) upgrade it to 5950X (i have to read more about that).
Im also planning to add new ram. Currently i have 6 year old RAM - 16 GB - 2x8GB (2 modules). I have these:

Corsair Vengeance LPX DDR4 16GB (2x8GB) 3000MHz CL15 White
CMK16GX4M2B3000C15W
https://www.ebay.com/itm/254347899188
(im not sure that description is correct on Ebay but i have these whites)

Heres a screenshoot of them from CPU-Z 2.03.1:
https://prnt.sc/kBYWXjRaKJK1

They sit in the Slot 1 and Slot 3 of ram slots (the Slot1 is the closest to the CPU). (And is blocked currently by my BIG air CPU cooler, and i would like the ram to stay in these slots ( 1 and 3) (1 especially) (otherwise i would have to dismount the cooler which i dont want (too much work, repasting CPU, cleaning, never done it, dont have proper tools, dont have new paste etc).
Here if you scroll down a bit youll find more info about the ram slots of my board:
https://www.asrock.com/mb/AMD/X370 Killer SLI/index.asp#Specification
(im not sure the info there is up-to-date)

And i want to add another 32 GB of ram (2x16GB Ram) to have a total of 48 GB of ram.
AFAIK i should choose as close of a ram to the original (old ones) i have as possible. Since i dont think i can get the same ram (since its 6 years old), the closest RAM i have found (and is available in my country; in "my" eshops; AND (!) with a good price) is:

CMK32GX4M2E3200C16

for example here:
https://www.amazon.co.uk/CORSAIR-VENGEANCE-PC4-25600-Desktop-Memory/dp/B07RW6Z692
https://www.corsair.com/us/en/Categories/Products/Memory/VENGEANCE-LPX/p/CMK32GX4M2E3200C16

Will these intended new ones (CMK32GX4M2E3200C16) work OK/Well/Without problems (are they "compatible") with my old ones (CMK16GX4M2B3000C15W)...??
Its the same vendor, they look the same (black/white color doesnt (shouldnt?) matter), old RAM max mhz is 3000 (2933 mhz) on CL15, new ones are max 3200 mhz on CL16. Old ones are 16 GB, new ones are 32 GB (48 GB in total i want).

The only thing i cannot understand is that they differ in the name in the "E(3200)" vs "B(3000)", im not sure what the "E" vs "B" difference/meaning is...? Other than that these should be closest to the old ones i can get...
Should there be any problem? Or is it quite a safe bet and i can order them...? If there is a problem (which one, in which area...?) what other RAM (32GB) would you recommend me to buy instead of these...?

Im planning to run them at the max speed i can, which is AFAIK those 3000 mhz (2933 Mhz) cause thats the (AFAIK) top limit of the old ones, so the new ones will have to run on 2933 mhz as well. (i dont mind running the ram at "just" 2933 Mhz)

Is everything ok? Should they run without any problems...? Or is there something im missing...?

Thank you

(BTW - if you are wondering - Currently the 16GB RAM runs only at 2133 mhz because thats the frequency they loaded in with- those 6 years ago, and i knew there are some problems with ram compatability with my motherboard back then, so i just thought to myself that ill wait for newer versions of BIOS, and than try to run them at those proclaimed 2933 mhz...) But years went by and i simply forgot :)... Thats why they still run on 2133 Mhz (all these years, lol) , and thats why i still have a super old version of BIOS (P1.3 - straight out of the factory, 1st bios version for the mobo i think - i just didnt update it).
(Im planning to update bios before putting in the new ram in of course.)

If you don't care what speed you're running your ram at. Pretty much any DDR3000~ ram should work. Honestly any newer ram you get now is gonna be faster than your old ram, and as long as you set it to the same speed as the old ram it should be fine.

That motherboard is already pretty touchy when it comes to RAM, but I used G.Skill and ADATA in my X370 with no issues. Sometimes simultaneously!

No one can answer this for you. This is something you simply must try and see if it works.

In general, I have had pretty good results with mixing RAM.

You can try choosing the XMP profile for both, and see if you can get all of the RAM to run with one of them.

Otherwise, you may have to manually set the speed, voltage, and timings. And you may have to lower the timings, overall.

Make sure to update your bios. It can often improve RAM compatibility.

Well, you're going to need to do that if you replace the CPU...

That said, I say, update the BIOS, hopefully there's a version that works with your current cpu and your desired cpu. Then, put in the new ram. Then, maybe, see if you can get it to run faster than 2133. Swap cpu then, I guess?
 
I have been debating this same thing the last few days. I got a 2x8GB kit of Dominator Platinum DDR4 2400 from 6 years ago also. I want to upgrade to 32 gigs because it seems many up and coming games are requesting it. Problem is you can't find these anywhere anymore, apparently. It's the 10-12-12-24 kit. I can find some on ebay that are different spec for somewhat cheap, but I'm not sure I want to go that route. Plus I don't like the idea of buying used ram to begin with.

I think I'm just going to get a new 2x16gb kit. There's quite a few 32GB CL16 3200 kits that are less than a hundred bucks.
 
Why are yoi afaif of using/buyinbg "used ram"...? I thought Used Rams (and even CPUs) are quite safe...? The only real problems with using used PC hardware stuff i read about is buying used HDDs (like the magnetic ones, not ssd), cause yyou simply dont know how the previous owner treated them, and how were they treated in transportation...

But RAM (used) AFAIK was always the safest from all used HW parts to buy used...?

Why are you afraid...?

I actually buy many, many used computer parts and peripherals, just not ram.

Be damn certain you know what you are doing before you do it.

The 5000 series compatibility tends to require a VERY SPECIFIC BIOS update. One that cannot be downgraded from and one that may very well strip out some of the features of your 300 series board. Check with the vendor, but the upgrade to run 5000 series CPUs will likely require a BIOS update that cannot be rolled back from. This is due to the fact that the 300 and 400 series boards were designed with too small a BIOS ROM region / maybe no real thought put into people running their 1st gen boards forever. You will have to use your 1700 to perform the upgrade and then pretty certain the board drops support for the 1700 as well after it's done.

RAM should fine, any 3200 Mhz kit will likely work. 300 series chipsets were touch an go initially with RAM, but that was all resolved over time after microcode updates. I had a 300/320 board that supported 3200 Mhz SoDimms, so I suspect you will be fine on the latest BIOS. It will be hit or miss for anything past 3200 MHz but you could try buying at 3600 MHz CL 15 Kit for cheap and then downclocking it if necessary. It's likely about the same price as the 3200 Mhz stuff and is the sweet spot for the 5000 series chips if you get it to run at the rated speeds (and it may very well run, properly, after the latest BIOS upgrade).
