Overclocking Ryzen 9 7950X3D with DDR5 memory
Overclocking Ryzen 9 7950X3D with DDR5 memory
Hello. I used a 7950x3d with 64GB Corsair Dom Plats 6400MT CL32. My setup reached stable speeds around 6200mts CL28-38-38-50-88. Here are my Aida64 bench results in safe mode. How impressive is this? I also tried 28-36-36-48-84 but it wasn’t stable during memtest. My VDD and VDDP were 1.45. I’m curious if there’s more I can do to boost performance. Unfortunately, running 6400MTs causes the system to crash and fail to POST.
It's good, though the performance isn't tied to RAM speeds since you have a large 3D cache. Still, keeping it at 6400 c28 is excellent.
Absolutely, that's quite intense—don't even say it's the original version of DDR5 RYZEN.
Can I adjust timing more precisely by increasing voltage? The tests with 28-36-36-48-84 didn’t pass memtest. OC is at 1.295, vddp/vddp at 1.45. Vddio is auto, and while X3D doesn’t depend on RAM speed, I’m curious if pushing it further would help for my own testing.
You'd be pushing the limits of what's possible with that kit, especially since you're just starting out with overclocking. Watching Ryzen DDR5 OC tutorials could give you some great insights, but make sure you're comfortable with the basics first.
Safe mode is not ideal. Your voltages look elevated, but you're not using the AM4 board. X3D thrives on fast RAM and precise timing.
I struggled to achieve such precision initially by increasing the voltage levels.
