Re-using current Ram for Ryzen 3900x possible?

AnthonyA85 · 6 Jun 2020 at 16:44

I need a bit of advice on RAM, my current system is using this: Corsair Vengeance LPX 32GB kit and i'm slowly collecting the parts for a Ryzen build, got the cpu, got the cooler, just need the case and Mobo (either a Gigabyte x570-I or Asus x570-I), i'm going to reuse the psu and gpu, i want to reuse the RAM as well if i can, would the current kit i'm using be good enough?

Or should I get a new kit? What speeds are optimal for stability with a 3900X? I'm aiming for 32 GB capacity.

@AnthonyA85 I use that exact kit, at 3200mhz on my 3900X. Runs flawlessly.

Hm, so i'd be able to reuse my ram just fine? I'd just have to OC it? It's rated for 2666MHz, and i was told in another thread that is a bit slow for Ryzen.

It'll run fine at 2666, you'll just lose some FPS. How much depends on resolution and GPU.

Well my main monitor is 1080p, i do have a QHD 27 inch Wacom Cintiq (goes up to 2560x1440 i think), only use that for zbrush though. As for my gpu, it's an RTX 2070 Super.

Sorry, I misread, my RAM is the exact same, but my frequency is 3200mhz, and enabled XMP in the BIOS.

Ryzen prefers faster RAM, so could be a consideration for more..

Personally it wouldn't bother me, especially as you have 32GB (like if it was only 8GB then it'd be upgrade both ways). I don't know anything about zbrush, so couldn't say what impact it would have there.
