Memory selection

[csendesmark]

Hello Forum,
Which memory modules should I pick for AMD Ryzen 9 9950X, most like with an ASUS ProArt X870E-CREATOR WIFI
The following two kit of 2 and costing about the same.

KINGSTON FURY Renegade 6400MHz KF564C32RSK2-96 with CL32-39-39 @1.4V - Product link
Corsair 96GB KIT DDR5 6800MT/s CL40 Vengeance XMP with 40-50-50-110 - did not even found the product on Corsair's site

Which is more important for memory bandwidth?
The frequency or the better latency?

Corsair, at least with DDR 4, have had well known issues with AMD rigs...not sure if they have been fixed or not in Gen 5, but just sayin

And I don't buy anything by Kingston, as they are a bottom-barrel brand that randomly & frequently switch components from 1 batch to the other, & use whatever is cheapest at the moment and therefore you can never know for sure what you are getting until you have them in hand to examine close up, and their RMA/warranty process is slow AF & a big PITA at best, and almost non-existent at worst

I suggest you stick with any other, better-regarded name brands like G-Skill, Patriot, Crucial, Silicon Power, Samsung (but watch out for the Sammy Tax") etc, hell even Thermalfake is ok most of the time

If you're gamin or editing rendering audio or video with it, then latency is probably more important overall IMHO.....otherwise it likely won't matter that much....

You will want to stick with 6000-6400 for maximum performance. However dual-rank 6400 might not work in 1:1 mode for your CPU (just a silicon lottery) . I suggest if you really need 64/96GB to get DDR5-6000 instead for hassle free experience.

The only semi-sane option. If your CPU doesn't do 6400MT/s, you still get a 6000MT/s XMP profile.

Looking at those primaries, I'm not even sure that's Hynix M-die. Could be some weirdo Corsair bin of Micron D-die running at 1.45V or 1.5V.

Depends on how much time you are willing to spend to tune.

Manually tuned tight timings outperform pretty much any higher clocked XMP/EXPO profile in the 6000MT/s to 64000MT/s range for AM5.
Mainly because XMP/EXPO still stick to the JEDEC refresh interval of ~3.9µs. Manually, you can increase that interval to over 20µs, but you'll should use a fan on your memory for that. Other sub-timings help as well, but that's pretty much the easiest way to improve memory speed quickly. However, most AM5 boards will provide some automatic tuning features for memory, I think even the ProArt series does.

there are no 96gb 2x48 that are less than 6400 to my knowledge. at least i didn't see any when i was looking the other day. its a niche kit.

I just found ~20 kits of 2 available at my local online retailers that are 96GB and clock below 6400MT/s by default where I live. Plus a few more that are out of stock.

Personally, I had no problems buying multiple 6000MT/s 96GB kits from Kingston, the slower variant of the one the OP linked.

hmm thanks for this, i just was looking on amazon so maybe my search just sucked. i will try some other sites. i think i will cancel my order if i can find some QVL 6000 kit

@csendesmark

The Kingston set out of those two for sure.

If you can find this set, it should be less expensive - the difference here in the US is about $70

Okay, I can get that - so you telling me that does not worth the extra price?
I will use them a lot with Handbreak to encode my 4K and 8K videos. And I noticed sometimes my CPU don't go to 100% which can only means the process is bottlenecked on memory bandwidth.

Also what is your comment on @bonehead123 's comment regarding Kingston's reputation?

As @ir_cow mentioned, getting 2x48GB sticks to actually run @6400MT/s is going to depend if your CPU memory controller can do that - some can and some can't. It's almost certainly not going to be plug-n-play.

I haven't used Handbrake in years so I can't be much help there, but the difference between 6000 and 6400 is very small.

I've used Kingston memory for, well, decades. I've never had an issue with them and I have had a 32GB set of the DDR5 Fury Renegade 6400MT/s set for almost two years without issue. I don't really care for their SSDs, but that's just personal preference. I haven't had an issue with the few I've used.

If your mobo has the ram as QVL though, it should though right? assuming you aren't using a low budget cpu, otherwise it wouldn't be QVL for the mobo?

You may need to run at 1:2 ratio, which will kill performance. So run: Yes, but at worse performance than 6000, 1:1.

Okay okay @Super Firm Tofu
Will take the easy road and follow @ir_cow and your advice...
No need to be fancy, I need stability!

I occasionally still use Handbrake since I completely went away from macOS for my post-production stuff, but not utilizing all CPU cores is normal for video encoding since the encoder has to wait for certain spatial and temporal data that can't be parallelized. It's pretty much what Amdahl's law describes.

If your mobo has the ram as QVL though, it should though right?

No. The ultimately limiting factor is your silicon in hand. Motherboard manufacturers happily list the results from their hand-selected golden sample CPUs for marketing purposes. If you are looking for somewhat useful QVLs, look at the one of the memory manufacturers. Kingston and G.Skill are typically the ones that are most accurate in that regard.

From my personal experience and observation of various OC-related websites, most Ryzen 7000 can do 6000MT/s in 1:1 mode, with a little luck you can get a CPU that does 6200MT/s in 1:1, and 6400MT/s in 1:1 is winning the silicon lottery. 6600MT/s in 1:1 seem to exist, but I've never seen one that passed an extensive stress test.
Since Ryzen 9000 uses the same memory controller as 7000, you can expect a similar distribution. Ryzen 8000 are monolithic and can't be compared directly.

Did someone say stability...I can recommend some ECC sticks that are running great for me at LOL-6000 CL44.

Not that important
I mean, I am okay with a regular non-ECC RAM, if it reasonably stable if not OC-d
And CL44 isn't that inviting

You may need to run at 1:2 ratio, which will kill performance. So run: Yes, but at worse performance than 6000, 1:1.

it annoys me motherboards say QVL, even if its worse performance than a cheaper 6000 kit. sigh.

 

[JWNoctis]

For what it worth, Corsair had a nice 6000C30 2x48GB Hynix M kit. I tried to overclock mine to 6400; It did not stabilize, and the performace would not have been very different anyway. 6400MT/s 2:3:3 on Zen 4/5 might be quite like 4000MT/s 1:1:1 on Zen 3 with that kind of memory capacity.

As to QVL, I stuck my neck out and chose a B650 board with a XMP-only kit. Neither were listed on the other's QVL, but worked out fine in my case.
