2 or 3 RAM Sticks on Ryzen?

Recommended Posts

Posted · Original PosterOP

Hello everyone, i have a question about my RAM on Ryzen. I have an Ryzen 5 1600 and 3x4GB HyperX FURY 2666MHz CL15(https://www.real.de/product/309797742/?sl=aHlwZXJ4IDRnYiAyNjY2bWh63jGTYJ5tCgavmhxeCgTeJigzQEb7MI-pFQTii3KigWI) When i first build my computer i just bought 4GB because i was on a tight budget. A few months later i bought 8GB on top of it (basically the same ram so 2x4GB). Now i ended up with 3x4GB Sticks and wonder what's better for Ryzen, having 2 or 3 RAM Sticks installed? Currently im using 2 Sticks and successfully overclocked them on 3000MHz with the same timings. When i install 3 Sticks i can't get past 2933MHz on CL15.

Also another question, would you guys recommend me buying new RAM or just buy another 4GB Stick to have 16GB in total?

2 sticks is better for overclocking. With 3 sticks you're only getting 8GB in dual channel, the remaining 4GB is single channel so expect a noticeable hit in performance


Another 4GB stick is cheaper right? Unless selling the current 3 sticks and buying a proper 2x8gb kit is cheaper.
