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

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.

8-Core X3D is for gaming, that is the genal consensus and what I focus on here. Of course none-gaming workloads will be impacted with different speeds. Just like the None-3XD ones. Still I'm not concerned over losing 15 seconds on a 13 minute blender render. If you don't have 13 minutes to spare per frame, buy a faster CPU.

Anything with a-die and tune it your self

Nevermind, I was wrong about 13 minute. its 20 minutes per frame A whopping 13 seconds faster with 6000 CL26 vs 4800 CL40. The 13 minutes IS the faster CPU hehe.

I was just being pedantic. The OP did not state what's the intended purpose of the rig, I assumed everything is on the table.

This is very true.

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.

I came here to say this.

Buy affordable DDR5-6000 CL30 with an EXPO profile and that matches your build aesthetic. Just about any 6000 kit is perfect for a 9800X3D. Fast system RAM is a crutch for when the L3 cache misses, and "the 9800X3D never misses"

I mean, there are probably some edge cases where faster RAM might provide a measurable advantage, but those really aren't very common and are likely to be bandwidth-limited so any 6000 kit (even a slower CL36 kit) would be ample. The goal is to stay at the 1:1 divider (Gear 1) so that's DDR5-6000 unless you want to try your luck with overclocking the IMC, which is damn-near a fool's errand on the 9800X3D.

Given the small number of high-profile X3D chips overheating and burning the PCB and socket, I'd be tempted to say don't even try and overclock a 9800X3D or push the memory beyond the sort of speeds that kits on the QVL are validated at.

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

Hello,

$200-ish buys you 64GB 6000.
If you want 32GB, G.Skill and larger heatsink best bang for buck is:
F5-6000J3038F16GX2-TZ5N (should be cheaper than RGB)
For 64GB:
F5-6000J3040G32GX2-TZ5N (should be cheaper than RGB)
Or 48GB:
F5-6000J2836F24GX2-TZ5NR (yeah no avoiding RGB with this one)
Depends on the prices really, if you find something close in price but with tighter timings go for it but don't exceed 1.35V for 32GB and 48GB, and 1.40V for 64GB.

Also look at Patriot Viper Venom. Very good kits.
PVV532G600C30K - 32GB
PVV548G600C30K - 48GB
PVV564G600C30K - 64GB

No point in paying extra for 3 fps, the larger capacity will serve you better in the long term.
At 6000 you're already running over the rated speed, no need to sacrifice voltage for under 30 CAS.
If 64GB is overkill for your future plans, no problem go 48GB.

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.

If it's possible (and you can afford it), get that CL26 kit and enjoy the fastest CPU/RAM combination on the planet

If I had a RTX 5090, I've consider getting something other than JEDEC 5600 Memory

Still I'm not concerned over losing 15 seconds on a 13 minute blender render. If you don't have 13 minutes to spare per frame, buy a faster CPU.

Nevermind, I was wrong about 13 minute. its 20 minutes per frame A whopping 13 seconds faster with 6000 CL26 vs 4800 CL40. The 13 minutes IS the faster CPU hehe.

XD!

Thanks everyone for the input, ideas, and data. That ram comparison for 9800X3D really shows how small the differences are for this CPU. Really, I should probably think about the 64GB version of the kit I have now. But I think I'll let it be for now. I could put the price difference into an AIO to pump hot air out of the case and improve airflow for my other components.

Plus, if I decide to change it later it shouldn't be that hard to flip lightly used CL28 DDR5-6000 ram...right?
