Best 32GB RAM kit for 9800X3D? (here are 5 I've found so far)

This is to be paired with the 9800X3D. I'm looking for a 32GB dual channel kit with great performance. I learned the hard way on my last build that the best kits don't stay available forever and I want this kit to be kick-ass so I never feel like it needs to be upgraded. That being said, I'm trying to keep the price sane. I think $200 is plenty for RAM and I don't want to exceed that. Here are some compelling options I found.


CMH32GX5M2X8000C36, 36-48-48-98, DDR5-8000 (gear 2) 9ns
CMK32GX5M2X6600C32, 32-39-39-76, DDR5-6600 (gear 1) 9.7ns
F5-6400J3039G16GX2-TZ5NR, 30-39-39-102, DDR5-6400 (gear 1) 9.375ns
F5-6000J2636H16GX2-TZ5NR, 26-36-36-96, DDR5-6000 (gear 1) 8.67ns
F5-6000J2836G16GX2-FX5, 28-36-36-96, DDR5-6000, (gear 1) 9.33ns


The system is primarily for gaming, but I care about general performance. Is it worth it to have a faster data rate in exchange for slightly worse timings? Is DDR5-8000 worth it despite Gear 2 meaning your memory controller speed is halved? Or does it make sense to get the highest data rate Gear 1 supports for a slightly higher CL timing?

Just not sure how much weight to put on timings, data rate, and first world latency
 
Welcome to tpu enjoy your stay mate...
 
F5-6000J2636H16GX2-TZ5NR is the best kit out of the bunch, but I recommend getting 48 GB at least. 32 GB is wood level now. :fear:

So you don't think the upsides of the Gear 2 kit is worth the downsides?

In the review guide, AMD states that 1:1 ratio is the one to go for.

TBH, Gear 2 is just there so they can promote 8000 / 8400 memory speeds on MB boxes / marketing slides.

Oh, hey Dro! I see that 48GB is double what the 4090 and 5090 have for VRAM which is probably why you recommended it. But I do not see myself buying a $2k-3k card so unless companies start putting more vram on their lower offerings I don't know when that will come up.

What is this review guide you speak of? Like, guide for reviewing AMD CPUs?
 
VRAM ≠ RAM

The review guide is the one companies send to the reviewers to guide them through the process of properly, well, reviewing the product.
That was lots of reviews ;)

Oh I know, Dro had shared earlier (different thread) that due to the way Windows handles memory, having a 2:1 ratio of RAM to VRAM might be advantageous.

Sorry I'm low on sleep, I do not get the joke with the winkyface :(
 
Honestly it doesn't matter with X3D. Buy whatever looks the best to you and is a size you like.

G.SKILL Trident Z5 NEO RGB DDR5-6000 32 GB CL26 Review - AMD EXPO

Today’s review focuses on the G.SKILL Trident Z5 NEO CL26 memory kit. Tailored for AMD Ryzen processors and systems, this kit aims to deliver peak performance thanks to ultra-low timings paired with a 6000 MT/s clock config, hitting the Ryzen Memory Controller's sweet spot.

They're less impacted by memory speeds/latencies, yeah, that is correct. Thank you for the remark!
 
1% lows at 1080p with a beefy video card will see some benefit with lower latency memory, but generally it's only special instance.

How much is some benefit?

So you're saying if you can afford it, go for it, but if you're on a budget, any 6000 kit will do no matter the CL timings when the CPU is an X3D, correct?
 
I picked up that 28CL 6000 kit before I realized the 26CL one existed.

I hadn't heard that the X3D chips were less sensitive to Ram speed. Maybe I'll forgo swapping the 28CL kit for the 26CL kit then. I have a few days left to decide.

I do hate the feeling of leaving performance on the table. Why buy the world's best gaming CPU and then knowingly give it slightly worse ram? IDK, maybe the money would be better spent on a case with superior airflow. My Fractal Define S is a solid case, but the 4080S is just too warm in it. I'll a few more fan configurations but I'm leaning towards picking up something designed for extreme airflow like the Antec FLUX Pro. Any recommendations along these lines would be welcome too^^ I don't love the grill design on the front of the Flux pro, but wow that airflow!

I mean, the reason these CPUs are so fast in games is that they don't rely on memory so much. That's what the cache is there for. Otherwise, if you're chasing memory bandwidth figures... you better pony up for a ROG Apex board + a 9950X or Intel CPU. The INT and FP performance of Ryzen X3D chips is actually relatively low compared to the numbers they pull on games and some memory sensitive applications.
 
I do like the topic.

I had on an i7-3610qm already 24GiB DDR3 DRAM. Max was 32Gib DRAM.

  • 32GiB will not be full futureproof in my point of view. I talk about the time perspective another 6 years.
Someone else in a german forum wrote, AM5 is most likely DDR5. the 5 stands for DDR5. I assume my hated ASUS X670 mainboard will be a long time with me.

I do not see much progress on the DRAM section. My kit lost a few Euros in price since may 2023. I do think hynix a-Die are the best choice.

  • I expect AMD to implement CUDIMM on AM5.

There was already a topic for it. When it comes, yours and my DRAM kit will be obsolete. I think there is a very small probability to get CUDIMM on my existing mainboard. Asus has very bad uefi firmware department. No money is spend in that section. Hardly any updates - and delayed updates.

-- I paid 100€ extra for my 2x32Gib DRAM kit in may 2023. My ryzen 7600x is very bad silicion, not worth tuning it more. the next cpu will utilise my hynix-a-die kit most likely much better

Isn't the performance worse on 48 GB kits compared to 32 and 64 GB?

No. The 3 GB chips have one of their subtimings looser than the 2 GB chips by default but almost all of them should reach about the same level, @ir_cow can explain better :)

The tRFC values are higher because 3GB ICs need more cycles (time) to refresh the banks. It's around 30% more. But so far I've been able to manually set any 48GB kit to 32GB tRFC values and be fine. Technically it's out of spec and well into the overclocking realm, but there is even more headroom past that. At least with SK Hynix ICs.

Check out the review I linked. Anything but DDR5-4800 will be just fine. I'm not worried about 1 fps. If I had a RTX 5090, I've consider getting something other than JEDEC 5600 Memory :)

Actually, it can matter with X3D. There's a reason X3D are marketed as "gaming CPUs": the size of the cache is tuned to accommodate as many games as possible. There are many non-gaming workloads that do not fit in the X3D cache, those will overflow to RAM. But it really depends on what you will do with the CPU.
