Terrible Stuttering with threadripper 1950x

AMD threadripper 1950x (Chipset drivers from AMD)

Asus Prime-a X399 (Bios 503)

64gb ddr4 3200mhz cl14 tridentZ

Samsung 850 Evo SSD 512gb

HyperX 120gb

EVGA GTX 660sc

WD 2tb HDD

Corsair H100iv2

Corsair Obsidian 750D Airflow

Corsair HX 1000w

Windows 10 Pro 64 bit

Nvidia Drivers 397.31

What i tried to fix the Stuttering :

1- Installing AMD Ryzen Master to launch in gamemode

2- Installing the lastest Asus AI Suite

3- Disabling the HPET

4- Disabling SMT

5- Installing AMD chipset drivers instead of Asus ones

- No results, my mouse lag on the desktop and my computer seems to throtling even if my temp are between 31 to 58 degree in CoreTemp or Ryzen Master.

- My chrome take 3 to 5 seconds to open, my hyperlink in my email take 10 seconds to open. My i7 920 D0 was 3 times faster for a 9 years old CPU.

- I was running my game at 60fps+ with my i7 920 and now with my threadripper 1950x, my games starts at 140fps but slowly drop to 30 fps in less than 2 minutes and the games are unplayable even in game mode.

I'm poor and handicaped, i saved all my pennies for 3 years to build the best CPU i can afford for my Zbrush Workstation. I'm litteraly crying now, even if i am 38 years old. 3000$ spent for something worse than my 9 years old Workstation. Please Help Me !

Re: Terrible Stuttering with threadripper 1950x

Asus AI Suite enables HPET. HPET is known to cause stuttering issues with NVidia GPUs, so i would look to uninstall AI Suite and make sure HPET is definitely off. I've seen many NVidia users have the same issue as you unfortunately. https://www.reddit.com/r/AMDHelp/comments/6wmhrf/help_threadripper_1950x_asus_zenith_x399_lag/

I have an identical system as you, same Motherboard and everything(Threadripper 1950x ), but with a Vega GPUs and see no stuttering at all.

Disable HPET: https://www.ghacks.net/2013/04/18/try-changing-hpet-settings-to-improve-your-pcs-performance/

Re: Terrible Stuttering with threadripper 1950x

Already tried that with no success.

I'm reinstalling Asus AI suite, just in case.

I looked into others forum and they said i need the 8 pins connectors + the 4 pins connector for the CPU. My Corsair HX 1000w doesn't have a 4 pins connector at all only the 8 pins one. In the User Manual; it say plug the 8 pins connectors or the 8 pins connectors + 4 pins connectors.

Can't find the HPET setting in my asus prime-a Bios ?

I used the CMD command to disable it : bcdedit /set useplatformclock false

Re: Terrible Stuttering with threadripper 1950x

Hmm, interesting, that could be an issue. In both of my Threadripper systems i have all the relevant CPU/PSU pins connected, definitely worth trying that first with a better PSU.

Yes it's a windows setting as Asus AMD boards don't have the option exposed in the bios. I would look at the PSU issue first, you need all the pins connected.

Re: Terrible Stuttering with threadripper 1950x

Why my HX 1000w from Corsair doesn't have that 4 pins connector ? Can i get a fitting for my extra 8 pins connectors i got ? I have two 8 pins but no 4 pins, weird ?

Where i can find a list of all PSU compatible with the asus prime-A and threadripper 1950x ?

All nvidia card get thoses issues ? Even the new GTX 1180 or gtx 1180 and gtx 1080 ti ?

Edit : Never Mention, i'm an idiot, i can split my 8 pins into 2x 4 pins. Sorry !

Re: Terrible Stuttering with threadripper 1950x

I'm not that familiar with Corsair PSUs or Nvidia GPUs, so best to direct any questions relating to those products to the manufacturer's.

Re: Terrible Stuttering with threadripper 1950x

warsoul, where did you get your chip set drivers?  I think you should get them here.  I assume you have the latest video drivers but how about the GPU firmware?  I would think you should best run factory default settings, including SMT but not HPET as amdmatt points out.  Is BIOS/UEFI 503 the latest?  What version of W10 (command prompt - winver) - I'm running 1709.16299.371 and 402 is available.  Enjoy, John.
