Brand new PC stuttering everywhere from plain desktop to games

[Encinitas2252]

Hello! Thank you in advance for your help.

OS: Windows 11 Home

Mobo: Asus ROG Maximus Dark Hero z790

CPU: Intel i9 14900k

GPU: 4090

RAM: G.SKILL Trident Z5 RGB Black DDR5 6800MHz

Cooling: NZXT 360 Elite

SSD: Samsung SSD 990 Pro 4TB

Since day 1, the computer has random micro stutters.  Even when no programs running on the desktop.

So far I have;

1. Change Power Settings to Gaming mode (high)

2. Change RAM speed in BIOS to 6800

3. Enabled XMP

4. Disabled Hardware-accelerated GPU scaling

5. Updated all drivers/ uninstalled GeForce experience and manually installed latest driver

6. Cleaned up the startup tasks

I know I've done other things but at this point I cant remember them all.  Can anyone help? I have searched through so many of these threads and haven't really found anyone with the same problem even (where it happens on desktop).

Thank you!

My suspicion is that your problems are likely related to memory stability. A good place to start is to reset the BIOS to defaults, leave XMP off and run some memory tests. You could use MemTest 86 in your BIOS for starters. Quick and easy. Let it run for the full cycle. 

If OK, turn XMP back on and see if stable. Then report back on your results... you need to find stable settings first as a baseline for further tweaks. There are better memory tests available, but you have to start somewhere for now.

Thank you. I had the same problem before I tweaked the memory stats but I will try right now, I appreciate it.

Also, the next thing I was going to do was update my BIOS from 1102 to 1202. Would you say this could help?

[JohnAb]

Hard for me to say, I don't have your board (or faster RAM like you). Maybe see if stable on defaults first with the BIOS you have now. If problems, then try the latest one. At least you'll have a comparison that way. 

Best just to try one thing at a time when troubleshooting.

As John has suggested, test at Optimised Defaults (No XMP).  Frame pacing issues can certainly occur if the memory is unstable.
