Need advice on RAM upgrades?
Hello everyone, I just set up a new PC and am considering upgrading my RAM. Here’s what I have so far: CPU – Ryzen 7 5800X; Motherboard – ROG Crosshair VIII Dark Hero; GPU – AMD 6800XT (ASUS TUF); RAM – Corsair Dominator Platinum 3200MT/s C16 (16GB x2). I’m replacing the old setup from a Ryzen 2700X and X470 motherboard. Should I upgrade to newer RAM for my current rig or purchase better replacements? Which option do you recommend, and what specifications should I look for? Thanks in advance!
I wouldn't settle for anything below 3200MHz for either setup. Considering this, it makes sense to opt for a fresh 3600MHz CL16 unit for your 5800X. The price gap isn't substantial, and it's much nearer the optimal range for that platform. The manufacturer doesn't really matter much. All these options rely on similar memory suppliers (Samsung, Micron, SK Hynix). As long as you choose a trusted brand (like Corsair, G.skill, Crucial, Kingston, etc.), you should be good to go.
The fastest RAM for Ryzen depends mainly on the clock frequency capability. For Zen 3, a stock speed of 1900MHz means you’d need around 3800MHz RAM for optimal performance, though that’s rare. In some setups, the FCLK can be adjusted up to 2000MHz, making 4000MHz a potential upgrade, but achieving higher speeds often reduces efficiency since the clock ratio drops. Pairing with 4400MHz would provide similar results to 2133MHz RAM. For Zen 2, the stock FCLK is 1800MHz, which fits perfectly. While you might push Zen 3 beyond 3600MHz, it’s less practical due to cost and availability. Generally, higher clockspeed is more important than precise timing settings. Aim for a clock rate close to 3600MHz with low latency for best results.
