Hi there, I'm setting up a retro gaming rig on an MSI K9MM-V board. It supports dual channel DDR2 with the CPU. I'm wondering if using DDR2 667 is sufficient or if skipping to DDR2 800 would hurt performance. Also, I haven't found any benchmarks comparing RAM speeds for that specific processor online. Let me know!

What kinds of games interest you? If speed matters, why are you using outdated equipment? Surely an upgrade to 800 would help, though it won’t make a huge difference in how it feels.

It's designed for a retro setup—NFS, MW, underground, Farcry, Crysis, GTA, James Bond, POP, and more. It helps you experience the right hardware feel. You can also run DOS games with the setmul tool and slow them down to 486 MHz.

It might make sense to adopt the standard 667MHz dims for better precision

Using older RAM kits means focusing more on speed and CAS latency than the newer DDR5 options, where small differences in timing matter more than big jumps. You'd need to compare both the RAM specs and your motherboard, CPU, and storage for accurate guidance. DDR2 was released around 2004, so it's quite different from today's components.
