Question Optimizing RAM Speeds for DDR4 3200 MHz

[vixtor2004]

Hello everybody,

I wanted to see if anybody had any possible leads on why my system is unable to handle bumping my ram speeds up to their rated 3200 MHz speeds in BIOS. I am currently running an ASUS ROG STRIX B450-F, a Ryzen 7 2700x, a 5070, and 32 GB of corsair vengeance RGB pro memory in a 8x4 setup. I was attempting to manually set the speed to the DOCP standard profile in my bios in order to hit 3200 MHz, but after boot looping it reset to 2133. After this I went down to 3000, which had the same issue, but after lowering again to 2800 it seems to be running stable at the moment.

Since the system is able to run at 2800 MHz on the 1.35 V DOCP standard profile, is it possible that 3200 is simply too power consuming for the system to handle? Or might there be other causes for these issues?

The 2700 has a max memory speed 2933 at default settings.
It may or may not work at 3200.
Depends on the IMC of the CPU. some will run faster than default ,some will not.

Zen and Zen+ are very hit and miss on the memory controller so chances are that's what you're being limited by.

Test a 2 stick kit in the proper 2 slots.

Nothing to do with power consumption, it's minimal anyway and frequency doesn't influence RAM power.
2700x and b450 MBs are capable of 3200MHz RAM (used to run that same combo) but......
You run into same problem all consumer grade CPUs have, With 4 sticks of RAM you run into IMC (Internal Memory Controller) built in the processor overload which limits high speed memory operation. With Ryzen it helps if RAM is single rank but not much.
PS. Overclocking RAM also means overclocking IMC and each one has own frequency limit over which it's considered OC. For 2700x it's 2933MHz over which even for one stick is OC.
