So, I hopped on the Ryzen bandwagon as well, upgrading from an i7 4790 based system to the current one. I got the parts on last Wednesday and since I've had extremely annoying issues with stuttering and lagging.

My build is the following:

CPU: Ryzen TR 1950x cooled by CM 240 Lite
MBU: AsRock Taichi x399
RAM: 2x 16gb (32gb total) Team NightHawk 3000 (@2666mhz) heatsinks removed for saving space.
GPU: Palit GTX 1080 JetStream
SSD: 1x 512gb WDC Black m.2 & 1x 480gb PNY SATA
HDD: 2tb WDC 7200rpm & 2tb Hitatchi 7200 rpm
PSU: Corsair RM 850w 80+ Gold Cert

Few things first:

The RAM heatsinks were removed after this issue was identified.

The PNY SSD, both HDD's and the GPU were cannibalised from the old system.

I have disabled HPET per instructions, have checked the RAM, have fixed old legacy registry issues that come with an upgraded Win 10, and the latest one I did just now was to enable SATA Hot Plug in Bios.

The bios is flashed to the latest version available on AsRock website. All the drivers are updated to their latest versions using TWO different driver managers along with Win 10 drivers and manual driver installation.

In a nutshell this is what I've done so far:

1. Flashed BIOS.
2. Enabled SATA Hot Plug.
3. Re-installed Win10, wiped the drive a couple of times before doing this
4. On first boot, WENT STRAIGHT to Windows updates and got the latest ones in.
5. After a reboot, used a driver manager (I used 2 different ones, Driver Booster and Driver Pack Solution) to install all the needed drivers.
6. After another reboot, got GPU drivers.
7. Got and installed the MOBO all-in-drivers.
8. Got and installed AMD chipset drivers.
9. Disable HPET.
10. Cleared Registry.
11. Tested RAM all ok.

The CM 240 Lite was reinstalled from a vertical position to a horizontal one, that being the reason for removing the RAM heatsinks, and is now giving an idle temperature of 31C, under rendering load being around 65C. The GPU temps are roughly the same. MOBO sits at 26C and the m.2 is around the same.

The problem at hand:

STUTTERING! I'm alright with lags, freezes and coughs while rendering my projects because all the cores are in use along with the GPU. I'm not alright to have to suffer from the same thing happening while I'm downloading something or multitasking. I mean, I've got 16 and 32 threads in my use, the year is 2017 and my cursor can't follow the movement of my hand?

The issue is most apparent when I'm downloading something such as earlier when reinstalling the Adobe CC programs onto the m.2 drive. The cursor lags and I see whole windows becoming unresponsive with the occasional desktop disappearance. This points to something being wrong with the m.2 drive or the connection to it I guess. (Cores aren't under heavy load here)

With my old system and with my laptop this issue popped up from time to time when downloading at higher speeds (the connection here is 200/10) and I concluded that the HDD couldn't write as fast as the data was streaming in. Now however, it should be the other way around given the m.2 writing/reading speeds.

So if I manage to solve this problem (seems a lot better now with the Hot Plug enabled), the thread here is for someone experiencing similar problems, and if not, PLEASE HELP MAH!

The tinkerer in me is rejoicing but the working professional is getting very annoyed and stressed because of approaching deadlines!

PS. From MSI Afterburner I can see that the CPU temps pulsate (2-5 sec @ 31C then a sudden jump to 40C and a decrease back). I'm new to liquid cooling, so is this normal? I guess it might be heated up liquid circulating between the sensors and the heatsink.
