Ram frequency HELP

Hey,

 

I'm assembling parts for my first self built PC (parts below) and have a question regarding ram.

 

I'm wondering what the benefit of faster ram is, mainly the difference between 3000Mhz and 3200Mhz ram for the build below. I got the advice that 3000Mhz can give issues with ryzen CPU's and that i should go for 3200Mhz. There is however a discount currenlty which means 3000 Mhz ram goes for €120 while 3200Mhz costs €150.

 

Is the 20% extra worth it and does 3000Mhz work properly/reliably in the first place?

 

edit: to I have to mess around in the bios to get the full benefit from the ram?

I don't know who told you that 3000MHz RAM would cause issues. I typically just recommend people get a 3000MHz or 3200MHz kit and whichever is cheaper is what they should get. There are margninal benefits to dual channel fast RAM with a Ryzen system, but the 200MHz differnce will not be noticeable nor will it cause issues. I have been using 32GB 3000MHz RAM that is not listed on the QVL by Asus and with Bios updates (I was an early adopter of Ryzen) the RAM issues went away. So as long as you are getting RAM from a reputable brand then there is no issue with your selection.

3200 MHz offers ~6.7% more memory bandwidth as well as reducing the length of a clock cycle by ~0.04 nanoseconds.

 

Higher memory speeds also increases the speed of Zen's Infinity Fabric, and this may provide a slight speed boost to your CPU in addition to the slight speed improvements of faster memory.

There is nothing wrong with 3000 MHz. I've been using a 3000 MHz kit with my Ryzen 5 2600 CPU for over a month and it's been fine.

 

And no, it's not worth it. Take the extra €30 and buy a game, instead.

Technically, yes. Probably not enough to matter, though.
