- Is 4800MHz CL40 fast enough for gaming?
- It works, but it is the entry DDR5 speed. Games run fine, though 6000MHz CL30 kits typically deliver a few percent more average frame rate on CPU-limited setups. The 64GB capacity matters more for simulation, streaming and multitasking.
- Will this run at 4800MHz without enabling XMP?
- Yes. 4800MHz with CL40-39-39-76 is a JEDEC standard profile, so most DDR5 boards boot at that speed automatically. You do not need to enable XMP or EXPO.
- Does it work with AMD AM5 and Intel 12th Gen and newer?
- Yes. It is standard DDR5 UDIMM, so it fits AM5 boards and Intel LGA1700 boards that take DDR5. Check that your motherboard uses DDR5, not DDR4.
- Can I add a second 64GB kit later?
- On a four-slot board you can, but four DDR5 DIMMs often force a lower speed, sometimes 3600MHz or less. Two 32GB modules are the safer configuration for stability.
- Is this a single 64GB stick?
- No. It is a kit of two matched 32GB modules, so you install both to get 64GB in dual channel.
- Does it fit under a large CPU air cooler?
- Ripjaws DDR5 modules use a relatively low heatspreader without tall RGB diffusers, so clearance is usually fine. Check your cooler's memory clearance spec to be sure.
- Where is the G.Skill Ripjaws 64GB DDR5, 4800MHz, CL40-39-39-76, Desktop Gaming Memory RAM (2x32GB) cheapest?
- At MBPC, for $649.99, as of our latest check.
