Micro Stutter Is Diabolical!
Micro Stutter Is Diabolical!
What voltage is needed for this part? It's unclear how voltage might lead to issues like stutters, though I'm not entirely sure.
I reached out to ASUS about a motherboard, and they suggested it might be the one I was testing. They also recommended checking other components, but I’m limited in what I own. They mentioned it could be the GPU or CPU, though I can’t confirm. I’ve kept an eye on both and usually cap my FPS at 120, so I’m not throttling performance or forcing the CPU to overwork. The GPU isn’t overclocked either. I plan to reset all settings in Windows and BIOS to their defaults to avoid any overclocking. Then I’ll see if the game stutter persists. If it does, I’ll return it for repair and try a new one. If it still stutters after the new one, I suspect the CPU is the problem.
I have reset everything back to defaults completely, even reverting to older drivers (allowing Windows to handle them), but the issue persists.
I also undervolted the GPU further, reducing power, temperatures, and clock speeds—yet nothing improved.
I want to note that recently I installed new RAM on the ASUS Strix X570-E Gaming motherboard, G.Skill RipJaws V Series BLACK 64GB (4 x 16GB) 288-Pin SDRAM DDR4 3200 (PC4-25600) CL16-18-18-38 at 1.35V, with all four sticks connected temporarily.
Unfortunately, this caused my drives to become corrupted. Interestingly, after running a memtest on them, no errors were detected. That made me realize I should perform another full reset and restart Windows 10 again.
After completing the fresh installation and restarting the computer, the corruption resumed immediately!
I removed two of the four RAM sticks, and the system stabilized afterward. It seems the RAM slots or PCI connections might be damaged.
It looked like my PSU was plugged into a power strip with many other devices, so I changed it to an outlet—still experienced stuttering.
I tried using a GTX 750 for testing, but it also stuttered.
This suggests that even after a fresh Windows install with a new motherboard, RAM, and GPU, and improved power delivery, the issue persists.
I’ll need to test with a CPU next to determine if the problem continues.
Did you check if your bios were updated to the latest release?
I believe it's typical. You're running a 3900X, which is a CPU made up of three sets of quad-core blocks, with the final block containing its own die. The transitions between these blocks, particularly from one die to another, have increased latency and can cause minor stuttering, but not actual lag. This setup works well because the application uses no more than four cores and you don't encounter any problems, though it's not always guaranteed.
The 3900x is built with two distinct 6 core 12 thread chiplets, and based on my experience, I’ve noticed no microstutters when using both slow and fast RAM. The idea that chiplet-to-chiplet latency causes stutters seems unlikely, as these latencies are generally within the 170 nanosecond range, which wouldn’t trigger such issues alone. If this were true, many users would be complaining on forums about AMD CPUs causing microstutters in games.
It is uncommon, but a faulty CPU can lead to various problems even when functioning. Have you experimented with another AM4 CPU to diagnose the issue? I previously used a 3900x on an ASUS x570-f with a 4x8 GB kit of 3600 cl14 15 15 36 RAM. I haven’t encountered any strange microstutters like you have.
