Question Noob question about ram

[spardason]

Hello!

Ok so, i have 2x4 gb RAM ddr4 , 2100 mhz and i bought today 2x8 gb RAM ddr4 3000 mhz...now my question is, how important are the mhz? whats the difference? all my life i thought the GB was the important part and not the mhz, but it makes me think, because other people seem to care about it, can someone please explain to me in a not very technical language the importance of mhz?

What Is ECC Memory in RAM? A Basic Definition

What’s the meaning of ECC memory? ECC memory in RAM explained.

Short story, fast memory makes little difference for Intel (1-3 FPS) but can make a large difference for AMD Ryzen (up to 20 FPS in gaming). In addition to speed a lower CAS latency is better (faster, more responsive) which is why you may see a kit (2x8gb @3200mhz CAS 16=$100) be much cheaper then one with a lower CAS latency (2x8gb @3200mhz CAS 14=$170) but besides that the specs are identical.

What cpu do you have? Faster ram will improve performance all around, and so will more ram. Amd ryzen needs fast ram to operate at its fastest, while intel will perform only marginally better with faster ram.

If you have an Intel system you will see little benefit, but with a ryzen system you’ll see more. A cpu works by pulling instructions from the ram and computing them, then returning it wherever. Ryzen needs speedier ram, Intel not as much.

People say 3200 MHz is the minimum for ryzen, but you’ll be perfectly fine with 3000.

I'd hold off for 3rd Gen Ryzen in a couple of months, well see more cores/threads and a higher boost/Overclock speed.

It's because of the way AMD Infinity Fabric (AMD's version of Hyperthreading) works. It's intimately tied to the ram speeds. DDR4 default speed is 2133MHz, and for Intel, there's very little difference, especially to games, between 2133 and 3200. But with Ryzen there's @ 20% performance gain between 2133 and 3200. After 3200, performance gains taper off while costs get high, so the value of 3200 in performance vs price is King. Best bang for the buck.

3000 is also a good option

Is there a big difference between 3000 and 3200?

This is common. Because of demands for 3200, it's artificially forcing prices that are within a few dollars. If 3000 is the same price or very close to 3200, which is the better deal?

Memory: G.Skill - Ripjaws V Series 16 GB (2 x 8 GB) DDR4-3200 Memory ($109.99 @ Newegg)
Memory: G.Skill - Ripjaws V Series 16 GB (2 x 8 GB) DDR4-3000 Memory ($109.99 @ Amazon)

Where i come from, prices are a little different lol
