DIMMDrive provides a front-end between Steam and its games and an old school RAM drive, letting you toggle which ones you want loaded into memory. It’s been garnering very positive reviews on Steam. What kind of gains should you expect?
Much of the ECC versus Non-ECC argument comes down to speed versus reliability. The reliability argument at least is easy to validate, but to settle the question of whether ECC actually lowers system performance, we ran a series of benchmarks with standard RAM, ECC RAM, and Registered ECC RAM that all run at the exact same frequency, timings, and voltage.
I often tell people that SSDs work better with more free space, so anything that increases free space will keep WA lower. The two key ways to expand free space (thereby decreasing WA) are to 1) increase over provisioning and 2) keep more storage space free (if you have TRIM support).
