What is the best RAM to pair with an RTX 5090?

Seconding the recommendation above! Honestly, chasing 8000MHz is just burning cash for like zero gain at 4K. I mean, you can grab Teamgroup T-Force Delta RGB 32GB DDR5 6000MHz CL30 for around $100 and its basically perfect. Spend that extra $150 on better storage instead lol. Seriously, 6000MHz CL30 is the absolute sweet spot for value right now and youll save a ton without hitting any real bottlenecks!

Totally agree with the above! Unfortunately, I had issues with those ultra-high speeds before and it was NOT worth the stress. For an RTX 5090, 6000MHz is basically the SAFEST bet for long-term stability i think. Since you do video editing, maybe grab the Kingston FURY Beast 64GB DDR5 6000MT/s CL30 kit? Having 64GB is way more practical than chasing 8000MHz speeds that youll just end up struggling with. Does that make sense?

In my experience, even with a monster card like the RTX 5090, you gotta be careful not to chase numbers that just lead to blue screens and frustration. Honestly, I feel u on the confusion around DDR5 speeds right now, it is lowkey a mess. Over the years, I've tried many high-speed kits, and while 8000MHz looks cool on a box, it's seriously a headache to get 100% stable for daily use. For your situation, I would suggest sticking with a rock-solid 6000MHz CL30 kit. I know it might feel like youre settling for a dream build, but basically, stability is king when youre pushing 4K resolution. I have seen way too many people spend a fortune on something like the G.Skill Trident Z5 RGB 48GB DDR5-8000 CL38-48-48-128 only to have their system crash mid-game because the CPU memory controller just couldnt handle the strain. Its just not worth the tiny FPS gain, i mean seriously. Plus, since you mentioned video editing, definitely go for 64GB. Modern games and production apps are starting to eat up RAM like crazy, and having that extra headroom is actually so helpful. I'd grab something like the G.Skill Trident Z5 Neo RGB 64GB DDR5-6000 CL30-40-40-96 or even the Corsair Vengeance RGB 64GB DDR5-6000 CL30. Both use Hynix chips which are super reliable... just enable the profile in BIOS and you wont have to worry about stuff breaking. Better to have a rig that actually boots every time than a paperweight thats fast but broken lol. gl!

Sooo, before you drop a ton of cash on those 8000MHz kits, I gotta warn you that chasing those top-tier speeds often leads to a massive headache. If youre on a standard 4-slot motherboard, getting 8000MHz to run stable is like winning the lottery because the integrated memory controller just cant handle it most of the time. Ngl, seeing a blue screen every hour really kills the vibe of a dream build. Anyway, for a powerhouse card like the 5090, here is what I recommend for technical balance:

• Aim for 64GB (2x32GB) capacity. Modern 4K titles and video editing really benefit from the extra headroom, especially with high-res textures.
• For AMD setups, 6000MT/s CL30 is the sweet spot to keep the Infinity Fabric at a 1:1 ratio for the lowest latency.
• For Intel, 7200MT/s is the max I would go for daily stability.
• Brands like Kingston or TeamGroup usually have solid binning for these specs. I am super satisfied with my 64GB setup, works well without any drama. gl!

Seconded!
