If the RAM isn't on your motherboard's QVL list then it likely won't run at their tested speed (3200MHz). So it's very likely that it's only stable at 2993MHz which showed you 0 errors in memtest86. You should be fine now if there's 0 errors on memtest86.
It depends really.
For example my Apacer Blade Fire is not in QVL. Rated speed is 3000Mhz but on my Ryzen system I can push it to 3333. Intel system can do 3466.
Load XMP profile it wont even POST. No matter XMP profile 1 or 2. It will just keep falling back to 2666mhz. I have to set manually with values I get from Ryzen RAM calculator, then set to 3200mhz for it to boot. Even then there's 1 error in memtest86. Have to fall back to 3000mhz for 0 error . Not sure its the motherboard or the RAM
I've just tested.
Ryzen 7 1800X with MSI Xpower Xgaming Titanium - Set to 3200 but falls back to 2666Mhz.
Ryzen 5 2600X with ASRock X470 Master SLI/ac - Set to 3200 via profile, stays at 3200Mhz no issue.
XPG D41 btw, what board was yours again? Gigabyte / AORUS right?
The stock cooler is more then enough to cool the ryzen if you do not plan to OC. Make sure you setup the cooler properly and have good air flow and ventilation in your casing.
On the contrary, the stock cooler actually works great even if you do OC.
It's just a matter of degree of OC you're doing, and also depending on the Ryzen model, some of them have "off" reading due to temperature reading off-set.
Based on my experience with Ryzen, pushing your memory speed gives you better return than overclocking.
Overclocking is even less required on 2nd generation thanks to the PB2, add XFR to that and it's already auto-OC on the fly.
About stock cooler, the Ryzen 2700X's stock cooler is a beefy model, easily worth the performance of many RM 200 - 300 cooler models.
MYR100 category, Deepcool Gammaxx 400 MYR200 category, ID Cooling Frostflow X 240 (provided your casing can accomodate it. I have a cheaplug Tecware mid-tower casing. It has no problem accomodating 240mm AIO).
Good stuff.
ID Cooling Frostflow 240+, I use that one for my 1700 OC last time.

You don't need to cool down CPU more, not for Ryzen. As I said, 2 reasons, 1) Ryzen is not a hot chip. It doesn't generate much heat. What's there to cool? 2) Ryzen has extremely poor OC headroom. Having premium HSF doesn't give much OC headroom. The limitation is the Ryzen chip as it just doesn't give you much overclockability.
I think depends on model.
Based on my experience, models like 1700 run really cool. 1800X can go quite toasty even after factoring temperature off-set.
2nd generation feels warmer than 1st gen, probably due to the PB2.
Ryzen 5 2400G for example runs hotter than I expected, the provided stock cooler shows show 90c+ when I do Blender test (video above).
About giving better cooler, the AMD Ryzen system will decide XFR based on how cool it runs.
Hi guys, recently built a rig with AMD Ryzen 5 2600 and using stock cooler..noticed that the temp for idling is around 45-50'c..is it normal? And when i load some games like GTA5, NFS Payback, Dota 2, and etc, the CPU temp can go as high as 85'C and GPU temp can go up to 90'C in few minutes..mostly i play games also less than 30mins..
I will test it (Ryzen 5 2600) later today and let you know if I encounter the same.
