Question New Build - - - constant entire system stutter ?

[nijik ajies]

Hey all. Just recently finished building a new PC a few days ago, on occasion when its powered on the entire system will be constantly stuttering. Mouse movements will freeze and jump, videos/programs will stutter at the same time, audio can audibly be heard fragmenting and stuttering as well. All drivers are up to date, BIOS is updated, no temperature irregularities, tried re-seating GPU and RAM, and so on. The only way I can figure out to fix this, is by going into BIOS on start and loading optimized defaults.

This makes absolutely no sense to me, and I'd like to confirm the problem within my motherboard's return window just in case that happens to be the problem. I've changed Windows power plan settings for maximum performance, as I've heard about some people having their hardware bottlenecked by Windows default power settings. I've also disabled a few RAM settings in BIOS, just in case (DDR5 Auto Booster, RAM Power Down, and Memory Context Restoration). The reason for this is because I could not get the PC to POST when AMD Expo was enabled. I believe it should be compatible to use Expo? But I exchanged for different RAM sticks because I figured the ram was faulty and even with entirely different sticks it still couldn't POST. I'm suspicious of the motherboard's RAM slots and quality in general.

Build Specs
Mobo: Gigabyte X870 Eagle WiFi 7
CPU: Ryzen 7 9800X3D
GPU: PowerColor Red Devil Radeon RX 6700 XT
Cooler: Lian Li AIO Liquid Cooler 360mm
RAM: G.Skill Trident Z5 Neo RGB, DDR5 2 x 16gb 6000mhz
PSU: MSI Mag 850w
OS: Windows 11

Thank you for your time.

Observe system performance using Task Manager and Resource Monitor. Use both tools but only one tool at a time.

Objective being to discover what the system is doing or trying to do when stuttering occurs.

BIOS is updated
For the sake of relevance, please state the BIOS version you're currently working with.

Rams populating slots A2 and B2?

What did you change to or from?

850W Msi Mag PSU
Is this the PSU you're working with;

?

When you installed the OS, did you install it in offline mode? Speaking of OPS, you forgot to mention the drive(s) you're working with. If you're working with NVMe drives, please mention which slots they're populating on the motherboard.

When I went to check the version, It was on F2 from August 2024. Which is odd, I 100% remember flashing the BIOS with the newest version (F3i from 12/19/2024) when it was first built a few days ago, and told me it was successfully updated, but it didn't seem to have actually applied. This could easily have been the source of the problem, I flashed it again just a while ago and system info is telling me it is now on F3i. I'll reply again in the future if this has fixed it.

RAM is in A2 and B2.

I originally used T-Force Delta RGB DDR5-6000 2x16gb, then returned and swapped for the G.Skill I mentioned in OP when I couldn't get EXPO to work.

Yes that is the correct PSU, the MAG A850GL.

Installed in offline mode I do believe, don't recall connecting Wifi or Ethernet when setting up first.

The storage is running exclusively NVMe, a 2tb Inland in the main PCIe5 slot, then a Samsung 980 and a Samsung 990 EVO in the other two.

On a final note, after flashing to version F3i, EXPO seems to be working for my RAM now.
I feel like a fool, lol.
Will come back to this thread in the next few days or so to confirm everything's working fine.

Well the issue still appears to be present. The only way I can get this to fix is by going into BIOS every single time I boot the computer and load optimized defaults and not touch a single thing. Can't have EXPO on either. Everything must be defaulted. At a complete loss. No clue what I should try now.

When you load optimized defaults and everything goes back to normal. My suggestion is to try each setting one by one to find out which one is doing it. Have you tried that? These ones you mentioned
(DDR5 Auto Booster, RAM Power Down, and Memory Context Restoration).
Oh , sorry. So it's every setting that is doing it or just one thing changed? Are you sure? And are they the same results?

Also, you mentioned drives. Is it possible you have a Sata drive to try out? Maybe you could install a fresh copy of Windows 11 on it and see if it runs normally with the BIOS settings that you need. That could rule out the operating system.

You might want to try out Windows 10 LTSC or some bare bones modded Windows to get rid of all the bloatware. Also, maybe it's something you installed like a bad driver. Just to see how it functions.

By the way what copy of Windows 11 are you running? Is it professional?

 

[Ralston18]

Even though it is a new PC try replacing the CMOS battery per the motherboard's User Guide/Manual.

Also check that RAM is installed correctly. Some motherboards require that the first physically installed RAM be placed in a specific slot - commonly DIMM_A2.

Read all fine print.

From testing the settings in BIOS, turning EXPO on, disabling/enabling Memory Context Restoration, and/or DDR5 Auto Booster seems to cause the stuttering. (The options for Memory Context and Auto Booster are, Enabled, Auto, or Disabled. Only Auto seems to work.)

So far today my PC has been fine without messing with any BIOS settings related to memory. Memory training issues maybe? I'll keep my BIOS on optimized defaults and keep an eye on it when I turn it on tomorrow and in the future. Maybe the MOBO just isn't ready for EXPO speeds somehow?

The RAM was installed in slots A2 and B2 on initial building and installation. Do you mean that to be 100% safe, I should have inserted only one of the sticks into A2 on the first boot, and then B2 later?

I'll get a replacement CMOS battery and see if that helps when I can.

 

[PiersPlowman]

The 9800x3D officially supports two sticks of RAM up to DDR5 5600 and four sticks at 3600 (JEDEC).

Is your RAM on the motherboard QVL list? You may have lucked out.

 

[dev_cyberpunk]

How are the voltages?
Because it could be just poor grounding.
Otherwise, I would load ubuntu on the drive and see if its just poor drivers or that junk operating system.

 

[Ralston18]

As far as I know, the initial RAM install can be two sticks. The requirement being that the first one installed is physically placed in DIMM_A2 as is common.

Or some other designated slot. Be sure to check the slot labeling. Both in the User Guide schematic and on the motherboard itself.

Sometimes there are additional instructions with respect to RAM installation and configuration. Those instructions must be followed as well.

Pay close attention to all of the fine print in the Motherboard's User Guide/Manual. The User Guide probably contains some instruction to go online to the manufacturer's website for updated information.

Also be sure to follow the User Guide's instructions with respect to clearing CMOS and replacing the battery.

Take another look at the front panel connections as well. They can be confusing and/or easily mixed up.
