Hello
Im building a new PC and in my build ill have the AMD Ryzen 5 1600 paired with MSI x370 Gaming Plus MOBO and the stock cooler. So I have some questions:
How much can I overclock the speed of CPU,
How much can I overclock the RAM speed( I will go with the 3000MHz or the 2133 MHz RAM speed depending on the answers u give me or recommend )
Please help
Thanks

1) It depends on your cooler. If you are only using the stock cooler that comes with the CPU, then not much. Further, it depends on how good you did on the silicon lottery. No two same chips ever overclock at exactly the same level.

2) I would not recommend overclocking RAM on a new chipset like Ryzen. Motherboard makers are still working out bugs, especially around memory. Further, in typical use (gaming, light video editing) there won't be much difference in performance between say 2400MHz and 3000MHz.

3.8 Ghz is good, but 3.7 is better, bcs you can lower CPU volt under Stock, and both ram timings and Hz will oc higher=less watt/noise/temp vs the extra 2.5%cpu speed/ 2-4 extra fps in games and dont forget the very high ramtimings..no way, in the end you will gain nothing. I always do OC where Ram Timing and Watt is my main concern. I have TridenzZ 3200, but ryzen/trident sweetspot on stock Volt is 2966hz.(even 3066 on these 3200=very high Ram timings).... My 24/ OC=3.7ghz-1.244V....2966Hz, 1.35V,14-14-14-30-52..CineB=1250, (14-13-13-30-52 was slower-wierd?)

Ryzen CPUs have a BIG performance boost when you increase the memory speed.

Show me the numbers in games and productivity like Vegas studio, hotshot. I'll wait. Oh by the way N00B, you do realize you are responding to a nearly year and a half old thread, right?

Ryzen do benefit from faster ram, at stock in bios my boys pc and my pc runs at 2333, xmp it runs at 3000 and you do notice it even on just normal desktop tasks. The stock cooler also will let you do a decent overclocking without overly high temps, my boys 1600 is oc'd to 3.8ghz at 1.26v and sits at 35c idle 75c load in a cheap gamemax case (his choice) with the stock cooler.

Here ya go:
https://www.eteknix.com/memory-speed-large-impact-ryzen-performance/

and an entire Reddit thread discussing the whys and wherefores:
https://www.reddit.com/r/Amd/comments/5xgw0q/memory_speed_has_a_large_impact_on_ryzen/

and another article demonstrating CPU performance improvement with RAM overclocking.
https://www.tomshardware.com/reviews/overclocking-amd-ryzen,5011-7.html

By now it should be common knowledge that Infinity Fabric, the data transfer 'blood supply' interconnecting Ryzen's CCX's, is tied to memory clock speed. So overclock RAM, improve data throughput across IF and CPU performance improves.

wow. year and a half old and still relevant

And yet none show real performance increases in my previously mentioned scenarios. Synthetics do not count as always because nobody cares about synthetic benchmarks. What we do care about is fewer seconds in video rendering and more frames per second in gaming. My point still stands as someone who has been building and overclocking PCs for over 20 years now. I've seen it all and know where to not focus on overclocking: memory speeds. Sure you can buy faster memory, but the ROI rapidly diminishes in most real world applications.

Many of those BM comparisons are real-world...including CPU/memory bound game FPS improvements. And agreed, not every use case will benefit the same way. Your use case examples could be optimized to execute out of cache, for instance, and so wouldn't benefit from main memory optimization even when it favorably impacts IF.

The key to optimum system performance for the broadest spectrum of use cases is to optimize all areas, including memory which directly affects infinity fabric in Ryzen. If you happen to have a highly specific use case then by all means optimize for that but that doesn't support saying optimizing memory clock-speed is worthless universally.
