Does Overclocking Memory Affect GW2?

I have heard that AMD's Infinity Fabric is sensitive to memory over clocks. Could this result in faster draw calls and more fps in GW2?

Ryzen likes fast RAM and you can see a performance uplift in basically everything with higher clocks, GW2 included.Can't tell you to which extent though in advance.3200-3600 MHz should be the sweet spot to get the best performance out of any Ryzen.

You can instead try to overclock the Infinity Fabric for very similar results

IF is not sensitive to overclock, it's sensitive to ram speed, in reality IF runs at the speed of your ram, faster ram equals faster IF. The two options are getting faster ram (new module or overclock), so IF works at the speed of the faster ram, or overclocking IF itself, or both.

If you have a really good memory controller on your 3rd gen Ryzen you can run 3800MT/s memory, but for most people 3600C16 or 3600C15 is the likely result. You can even run 4000MT/s on Ryzen but the 1:1 Infinity Fabric ratio will be overriden which will result in lower performance in latency bound applications such as gaming. This isn't even counting all memory subtimings, which have an impact as well.See https://www.corsair.com/corsairmedia/sys_master/productcontent/Ryzen3000_MemoryOverclockingGuide.pdfand https://www.anandtech.com/show/14525/amd-zen-2-microarchitecture-analysis-ryzen-3000-and-epyc-rome/11

For mainstream i5/i7 and i9-9900k Intel chips as long as you have 2933MHz or above the performance improvement will not be as large due to ringbus architecture. See https://www.eurogamer.net/articles/digitalfoundry-2019-intel-core-i9-9900ks-review?page=4

There really isn't any reason to run slower than 3000C15 or 3200C16 unless you have a locked Intel CPU that only supports 2933MHz such as i5-9600 or i5-8400 (DDR4-2666). The typical 3000C15 or 3200C16 kit costs within $20 of a DDR4 2400 or DDR4 2666 kit because largely they are using Hynix memory ICs rather than Samsung B-die or Micron E-die .
