Should I overclock CPU along side overclocking GPU

[Livewire88]

Hello everyone,

I recently started tinkering with overclocking using MSI afterburner, and I have some questions.

1. When adding an overclock, if CPU/GPU temps are well within tolerance and there is no artifacting. Does this mean the overclocking settings are safe to use indefinitely?
2. I play games exclusively in 4K, which means I am GPU bound all the time. Is there any need to overclock my CPU?
3. Does a "mild" overclock have a drastic effect on a GPU's longevity?
4. is there any value in overclocking for the difference it makes to FPS against the possible wear it could cause on the card?

I have increased the core clock by 320MHz and Memory clock by 350MHz on my MSI RTX 5080 Vanguard, its upped FPS by around 8-10. CPU is a AMD Ryzen 7 7800X3D for info.

Thank you

Hi

1. Yes in Part but overclocks can become unstable over time

2. Best to test with and without the Overclock to compare looking at the 1% lows also.

3. Usually no but depends on the silicon lottery.

4. How much of a percentage gain would be relevant, you say 10fps more at 4k bit what's that as a percentage?

Another you could tinker with is memory timmings or speed.

7800X3D is hardware locked at 5050MHz so you can use a couple of BIOS options to get the CPU more consistently at or near the 5050MHz limit.

Personally I just set the Platform Thermal Throttle limit in BIOS to 75C and enable an all core Curve Optimisation of Negative 30 (stable on my CPU) also in BIOS. The PBO settings don't seem to do all that much on my Asus B650i motherboard so I left PBO set to Auto.

I use a 280mm AIO to cool my CPU.
