Following a CPU upgrade, the PC experiences stuttering during simple tasks but remains stable when gaming?
Hello. I recently changed my CPU from a Ryzen 7 5700G to a Ryzen 7 5700X, and since then my PC has been experiencing stuttering during everyday tasks like browsing, moving tabs, and music lagging when not in focus. I've attempted to reinstall Windows, update the BIOS, and even performed a full reset, but nothing helped. My computer only stutters during these basic operations, not when playing games. I'm running 32GB of RAM, and the CPU temperatures are normal (78°C under load). My graphics card is an RTX 4070 Super with 12GB of VRAM.
Welcome to the forums, newcomer!
When posting a thread of troubleshooting nature, it's customary to include your full system's specs. Please list the specs to your build like so:
CPU:
CPU cooler:
Motherboard:
Ram:
SSD/HDD:
GPU:
PSU:
Chassis:
OS:
Monitor:
include the age of the PSU apart from it's make and model. BIOS version for your motherboard at this moment of time.
600w is under the requirements for 4070 super 650w; I really dislike prebuilt units that skip basic manufacturing. I’d upgrade the stock cooler to one with at least 5 heatpipes. It’s either RAM or temperatures are the issue, and I’d switch the power plan to performance mode.
The problem arose only after I upgraded my CPU, meaning the GPU shouldn't be the main factor. Both CPUs and GPUs run at 65W, so it shouldn't impact performance. I considered RAM as a possibility, but it wouldn’t explain why games run better after the CPU upgrade. I checked the Task Manager during stutters and noticed a significant increase in CPU usage, which might be relevant.
As previously suggested, which BIOS are you using? Did you refresh it prior to installing the new CPU? If the version is outdated, that might be the cause. Are your RAM settings set to XMP? You can verify all of this using CPU-z.
Additionally, as discussed earlier, your power supply is insufficient for your GPU. For a standard 4070 Super, the minimum recommended power is 650w. They suggest 700-750w for overclocking. Most generic PSUs in HP prebuilt systems tend to be unreliable and may not deliver consistent, stable power. My 4070 Super consumes around 240w under load, with spikes reaching close to 300w.
Upgrading a prebuilt PC can be unpredictable. Numerous uncontrollable factors come into play due to fixed BIOS settings.
I'm using the latest F.34 BIOS, which is the newest release. I installed the most recent version before adding the new CPU. The BIOS check now shows no way to activate an XMP profile, though I could switch to an "Amp" profile or even a custom one with adjusted speeds.
I realized the power supply was insufficient for the GPU, which likely accounts for the lower performance compared to other machines with similar components. If I can't fix this issue, I might be able to replace the GPU, CPU, and RAM, then rebuild the system into a new PC.
This would be a great idea.
I've a similar set up as yours, only my CPU is 5600x. Same gaming performance but your 5700x is obviously better at multi core workloads. These systems are plenty capable of playing AAA at 1440p (where the load shifts more to the GPU than CPU) and having a great experienc.
One thing to try, and it may not be possible on a proprietary mobo, is to clear CMOS. Check the support docs for the PC, and see if it's an option. In CPU -z does it specify the actual mobo, or only the HP code? Is the F34 bios from HP, or a board manufacturer? Clearing CMOS and resetting bios defaults could solve the issue.
For the mem, if it's not running in XMP, this could also cause the stuttering and tank performance, specially in gaming. You can use CPU-z (SPD + Memory tab) and post a picture of both, and we can look at what speeds the ram is running, if XMP is active and also if it's in dual channel mode.
Reinstall the chipset drivers and graphics card drivers again. Consider forcing PCIE 3.0 mode in BIOS as well.
CPU-z only identifies the motherboard as HP-made, and I've also obtained my drivers from HP. I've attempted three distinct ways to reset CMOS, but none have resolved the problem. The only remaining option I've considered is physically removing the battery or shorting the CMOS reset pin. The challenge is that I can't locate the battery or the shorting tools, so I'll proceed with this as a final step, possibly needing to replace the GPU.
