Best DDR5 RAM for Intel Core Ultra (Arrow Lake)
Intel Core Ultra 200S "Arrow Lake" on LGA1851 runs DDR5-6400 natively, and the Arrow Lake Refresh raises native support to DDR5-7200 with CUDIMM modules (whose onboard clock driver enables stable 8000+ MT/s). These live picks balance speed, capacity, and current pricing for an Arrow Lake build.
How this guide stays current
RamRadar re-ranks these picks using live pricing and current fit signals instead of leaving a static affiliate list untouched for months.
Market-aware ranking
We favor kits trading well versus their all-time low so this page points to buyable options, not stale listicles.
Fit before hype
Capacity, platform fit, and real-world value matter more than headline specs that rarely change your outcome.
Trust-aware offers
We bias toward known brands and cleaner retailer signals so weak or misleading listings do not dominate the recommendations.
Quick recommendation
- •DDR5-6400 is the native baseline; CUDIMM kits unlock DDR5-7200+ on Arrow Lake.
- •32GB is the mainstream baseline; 64GB for creators and heavy multitasking.
- •During the 2025–26 surge, prioritize kits near their all-time low.

FAQ
What RAM speed is best for Arrow Lake?
DDR5-6400 runs natively; with CUDIMM kits, Arrow Lake (and especially the Refresh) supports DDR5-7200 and higher. For most builds, a quality 6400 kit is the value pick.
What is a CUDIMM?
A CUDIMM adds an onboard clock driver (CKD) that re-times the memory clock for stability at very high speeds (8000+ MT/s). Intel Arrow Lake is the mainstream platform that benefits most from it.
