Question Overclocking RAM

[Zizo007]

Hello, I am trying to OC my bdie 4x 8gb 3600mhz gskill ram. With 2 sticks I am able to achieve 3800mhz c16 with 1900mhz FCLK however with 4 sticks anything past 3666mhz pc won't boot no matter how much voltage I give the ram and the cpu memory controller. Currently running 4x 8gb 3666mhz c16, I tried tightening the timings to c14 but pc eventually crashes or won't boot sometimes regardless of how much voltage I give.

Is there crappy bdie ram? Though with 2 sticks it did 3800mhz c16.

you have hit memory controller limits

I forgot to say its using a Ryzen 3700X with an Asus tuf x570 motherboard.

So if I get a 5800x3d I will achieve better with 4 sticks?

If you want faster ram, buy faster ram in the first place.
Ram chips are binned, and if they were capable of 3800 speed, they would be sold as 3800 speed for more.
You could get lucky, but do not count on it.
All ram must be managed with the same specs of speed voltage and timings. It is much harder to control 4 sticks than 2.

How well ram does is controlled most by the motherboard.

Then, there is the question of how much would you really gain?

Impossible to say for sure... Maybe, maybe not. But you will get a faster CPU for gaming ... With vastly larger gains than what you'll get with a memory overclock (in certain games).

If you want peak performance you may have to stick with 2 sticks. 4 is more difficult for the CPU memory controller and pushes the limits of the mobo's capabilities farther than 2 sticks.

Tightening timings with 2 or 4 sticks at 3600mhz or more will also give you gains, so there's still performance to be had either way you go... Just a lot of work testing limits and stability.
