I read a post on Reddit saying past +300mhz memory clock, you actually lose FPS on the 5080, but don’t have this experience. I’m currently running 18000mhz memory/ +3000mhz memory, core is at 3330mhz, and it’s rock solid stable. I can run any benchmark, any stress test and validate these numbers and prove the VRAM overclock is making a difference. It scales linearly too. Every 500mhz jump is giving almost exactly the same fps increase whether it’s synthetic loads or real world gaming. I’ve use both cyberpunk and black ops 6 benchmarks for a lot of the overclocking as they’re both fairly short, consistent and I know I’m not capped by anything else.

Can anyone else confirm my experience so I don’t feel like I’m going insane? I see a clear fps increase trend as the memory increases all the way up to 3000mhz, that’s the maximum I can overclock within Zotacs utility, so I cannot go beyond that. My VRAM reports max of about 60c temps in HWMonitor. Hotspot reads as 255c, but this is clearly an error so I have no choice but to ignore that for now.
