Issue with micro-stuttering on a brand new PC?
Issue with micro-stuttering on a brand new PC?
I've been working on resolving this for three months now and feel completely stuck. I recently installed a new PC, leaving out the GPU and storage components.
Technical Details:
- Motherboard: ASROCK Z790 Pro RS DDR5
- CPU: i5-12600k (operating at default speeds)
- RAM: Kingston Fury Beast DDR5 6000mhz, 2x16gb, CL36
- GPU: Gigabyte GTX1080 Xtreme Gaming
- Cooling: beQuiet! Pure Rock 2 (provides adequate CPU cooling, idle temps 30-36°C, peak under load 60-65°C)
- PSU: Cougar GEX 750W 80+ Gold, fully modular
- Storage: Kingston A400 120gb (boot drive only), WD Blue SATA SSD, Samsung generic NVME SSD
- Case: 1stPlayer T7-P
I previously shared a question about RAM problems before. The issue arose when using XMP 6000mhz; the PC would crash randomly, typically once daily, lasting up to eight hours without issues. Event Viewer displayed a "Kernel Power" error. Adjusting RAM to 5600mhz via XMP resolved it, and manually setting it to 6000mhz also worked temporarily. However, I haven’t run enough tests to confirm stability, as the PC was taken to a repair shop the following day while still under warranty.
After fixing the RAM problem—since I’m comfortable running at 5600mhz—I’ve shifted focus to another challenge: microstutters in most games. These aren’t noticeable FPS drops but feel like brief stalls or freezes. In more demanding titles (Squad, Escape from Tarkov), these occur more often and last a second. Lighter games (CS2, R6 Siege) show millisecond stutters. I’ve tried various solutions: BIOS updates, clearing CMOS, disabling E-Cores in BIOS, reinstalling GPU drivers, adjusting Windows settings, updating all drivers, setting NVIDIA performance mode to "Max performance," managing C-States, and using Latencymon. None have resolved the issue.
I suspect hardware problems might be at play, especially since my storage and GPU are functioning correctly compared to my previous setup. The i5-12600k performed well in benchmarks, so it’s unlikely to be the cause. My Cougar GEX PSU could also be problematic due to voltage regulator issues common in 12th-gen chips, which may struggle under load. The motherboard remains a possibility but is harder to test.
At this stage, I’m uncertain whether the problem lies with the PSU or the motherboard. I’m running out of ideas.
Did you reinstall Windows or simply upgrade to version 11?
Monitor the GPU temperatures.
Verify storage using the manufacturer’s utility and consider updating the firmware later.
Test RAM with MemTest.
I upgraded to Windows 11 first, then performed a complete reinstall via USB using the ISO from the Microsoft site – I also have a valid key, confirming it’s an authentic copy.
GPU performance drops to 62C under load; I’ve limited FPS in every game because my monitor runs at 75Hz. Attempts to increase FPS were unsuccessful.
I should note that I also tested another NVIDIA GPU (borrowed a GTX1650 from a friend) just to ensure it wasn’t my 1080, but the problem persisted.
Storage is running the latest firmware and drivers.
I completed memtest86 on both drives individually, spending roughly two hours per drive with the longer test; RAM detected no errors.
DDR5 supports ECC but isn't identical to traditional ECC memory, which means it can handle minor memory issues. These might cause the stutters you notice and suggest a possible memory concern. The A400 boot drive could be contributing to the problem, especially if it's full. Check if your page file is stored there; consider moving it to the Samsung drive if space allows, and keep about 20% of the drive empty for TRIM operations. Modern games often perform on-the-fly decompression of files and textures, which can strain slower drives. If your drives are sufficiently slow, you might see similar issues. You were likely using the same hardware before, but Windows 11 uses more memory for performance, potentially limiting system memory bandwidth. It could be that the system is depending more on the drives than on loading data into RAM. The power supply should be upgraded generally, especially if it's an older model like the GTX 1080—replace it with a unit offering a 10-year warranty from brands such as Corsair, Thermaltake, MSI, ASUS, etc.
I revisited Windows 10 after realizing that upgrading to Windows 11 didn’t fix my issue. On my boot drive, I have roughly 50-55gb free space. In my previous build with a budget MSI AM4 board, a Ryzen 7 2700 and two 16GB at 3200Mhz, I experienced no microstutters in games such as Witcher 3, CS2 and R6 Siege for instance (excluding squad or hell, since maintaining a smooth 75fps was challenging due to my CPU bottlenecking my 1080). My power supply is brand new, purchased with the latest build, but if that proves to be the problem I’ll probably swap it in for the Corsair RM850x. Should everything else fail, I’ll likely sell the motherboard/CPU/RAM package at a slight loss and upgrade to an MSI B550-A PRO paired with a Ryzen 7 5700X3D and my existing DDR4 RAM.
inspect the motherboard's CPU socket for any bent or discolored pins. ensure the CPU cooler isn't too tightly secured on the CPU. determine the CPU's running frequency, as it might fluctuate. identify the RAM slots you've used. locate the PCIe slot where the GPU is installed. find the M.2 slot for booting and system storage.
The PC was put together in the workshop I purchased it from. The cooler appears correctly configured because I installed my storage and verified all connections. If they cannot resolve the problem, I will inspect the CPU socket when they return it.
The frequency fluctuates significantly—rising during gameplay and dropping to as low as 1GHz when idle to conserve energy. It changes a lot depending on what I’m doing. I haven’t disabled this setting through BIOS yet, since I’m not present at the shop, but I’ll attempt it once I receive the unit again (in case they fix it there and figure out the issue). I wouldn’t expect this to solve the problem, as these CPUs are built to handle such variations. RAM is placed in the proper slots (B2 and A2).
what you meant was whether the frequency changes significantly while under load and during stuttering. Did you install any tuning tools such as afterburner or something similar? Check the CPU using the intel diagnostic tool once you're back.
I ran the CPU through Intel diagnostic tool and it passed. Before installation, I used afterburner and rivatuner and checked the core frequency; everything seemed normal. While gaming, the frequency fluctuated between 3.7ghz and 4.2, depending on the game and situation, but stutters didn’t appear since the changes in frequency were happening. I’ll recheck when I get it back to confirm.
Received a call from the repair shop recently. They confirmed microstutters occurred during game testing on my PC. After switching to one of their SSD drives and disconnecting my boot SSD, the stutters disappeared. The technician suggested it might be due to my Kingston SA400 (highly unlikely, as it worked before) or the Razer drivers, given I don’t use Synapse. I haven’t installed Razer software because I’ve heard it can cause problems on many systems. I’m hoping the issue is straightforward—once I restore my PC and test with a standard office mouse, the problem should resolve. If not, the SA400 SSD will need to be replaced.
