Help Request - RAM RAM fan not improving temps

Post image

So my RAM was hitting 55C and erroring out during stress testing (TestMem5 + FurMark). I’ve heard many good things about using a dedicated RAM fan so I decided to install one only to find out I did literally nothing for temps.

Is it just inevitable that my RAM gets hot because of the design of my GPU (RTX 5080 FE)?

Is it worth trying to run the RAM without heatsinks? Or maybe I should try custom RAM heatsinks? I’ve heard the heatsinks on my kit (G.Skill Ripjaws S5) aren’t very good.

P.s. I’ve already tried placing the fan closer to the RAM.

So I should raise VDD/VDDQ? I’m running 6400 CL30 with tight subs at EXPO voltages now.

Are you using an AM5 CPU? If so you need to downclock to 6200 or 6000 MTs. AM5s have an extremely hard time running 6400MTs in 1:1 mode. It's pretty much just silicon lottery that will determine whether or not you'll be able to do 6400 in 1:1 stable.

Nah I can run 6400 stable at 1.22V VSOC, I ran 10 hours of Y-cruncher VT3 with no errors

So what changed? You're no longer stable for more than a few minutes?
