Question(Stutter all games) B760M GAMING PLUS WIFI + NVIDIA 4080 Super + Intel(R) Core(TM) i7-14700KF
Hi everyone,
I have been struggling with frametime spikes for a few months now and I really need some help. My PC is a high-end build, but I get noticeable stutters in almost every game I play.
The most confusing part:
I already replaced my motherboard. I switched from a Gigabyte model to a new MSI B760M Gaming Plus WiFi, but the stuttering is exactly the same.
My Setup:
CPU: Intel Core i7-14700KF with Liquid Cooling
GPU: NVIDIA GeForce RTX 4080 SUPER
RAM: 64GB DDR5 (2x32)
Storage: 2x Kingston 2TB SSD
OS: Windows 11 Pro
I have monitored everything with several tools. Temperatures and clock speeds look normal. I only see a massive spike in the frametime graph when the stutter occurs.
There's only one game where this doesn't happen to me, and that's Forza.
Things I have already tried:
Clean Windows 11 installation via USB.
Used DDU to wipe drivers and tried multiple versions.
Passed all stress tests with no crashes or overheating.
Replaced the motherboard entirely.
I have tried every "fix" I could find online but nothing works. Since the motherboard was already replaced, I am starting to wonder if the CPU or something else is the cause.
Any advice would be greatly appreciated. Thanks!
What is the specifications of your power supply unit?
Which game resolution are you using?
What are the current temperatures of your CPU and GPU when idle and during workload?
Are you performing any overclocking on your CPU, GPU, or memory?
The two Kingston SSD variants are listed, along with the PSU's make, model, and variant.
What is your RAM model and clock speed? Did you turn on XMP? Which games are you currently playing? Stuttering has become an issue in many titles lately due to UE5. Upcoming engine updates should address this, though existing games built with it often still experience some stuttering, particularly at 4K resolution. I share similar specifications as yours (except for the CPU, which is a 9800x3d) and none of my games consistently stutter except those developed using UE5. Most UE5 titles I've tried had stuttering issues—Silent Hill 2, Oblivion remaster, Borderlands 4, Avowed, etc.—though some improved after patches, but the problems didn't fully disappear.
The model PSU is a MARS GAMING MPB1000SIM. My display is 165Hz 1080p (MSI MAG272C), but I typically play at 60fps 1080p. For comparison, the stutter usually matches half of that; for instance, at 120fps the drop occurs around 63fps, and at 60fps it's generally between 32-37fps.
At idle, the GPU hits 37 degrees and the CPU 27 degrees; during gaming, both stay within 52 to 60 degrees. The system isn't overclocked—no extra settings have been changed. It's exactly as I got it. Just enable XMP and the Resizable Bar.
The RAM model specifications are 32GB DDR5 5600MT/s CL36 FURY Beast Black EXPO.
I attempted to activate XMP and Resizable Bar, but the results remained unchanged.
Stuttering was observed in Minecraft, Fortnite, The Crew Motorfest, and Beam NG. Forza Horizon 5 is the exception with no noticeable stuttering.
Cyberpunk 2077 also causes stuttering, though not consistently every 10-30 seconds.
That is a budget drive without DRAM cache, which could affect performance during intensive operations such as loading big levels or updating games. The lack of fast data handling might cause the drive to depend on slower system RAM or basic NAND speed, resulting in noticeable delays. Even though newer drives use HMB, they may not offer the same consistent, low-latency access as dedicated DRAM SSDs, potentially causing occasional freezes or stuttering. It's unclear if this is the exact cause, but it would be worth checking with a higher-quality model. Also, I haven't heard much about that PSU before.
I would first swap this used PSU. Never cut corners on the power supply. That's the first rule.
Also, 5600 MT/s at CL36 is a bit slow for memory. Intel CPUs aren't as responsive to RAM speed as AMD Ryzen CPUs are, but I'm curious if your stutters might be related.
