3080 Ti transient spikes triggering OCP on a 1000W PSU?

[Tetras]

Okay so I get the same issue in Battlefield 2042 with a power cycle within 5-10 minutes. It's also happening in Balder's Gate 3 but very occasionally.

• I replaced my Focus GX with a Corsair RM1200x and the problem actually got worse, I couldn't even load into a game of Battlefield before the PC power cycled, it would just happen in the menus.
• I swapped my 3080 Ti with my housemate's 3080 and bizarrely neither of us had any issues, he also has 5900X but only a 750W PSU. We matched settings best we could, so I don't think it's the GPU.

This has left me confused, it points to the combination of GPU, Motherboard and CPU but I'm not sure why or how? Sure enough, if I lock my CPU to 4.25GHz (all core) it completely fixes the issue - presumably due to the lack of 'bursty' behavior.

I'm sort of okay with accepting the motherboard is knackered, but I'm not sure why this issue is present with my 3080 Ti but was unable to be replicated with another 3080, they both take 75W from the PCI-E slot?

What's the difference in cooler design and power consumption between the two cards?

It may have got lost in the thread but I did buy a new PSU as I was convinced it was transient spikes causing problems, however the power cycling still happened. That coupled with the GPU running fine on my friends 750W system means I'm discounting GPU issues. Incidentally I always run my card with an undervolt curve and a power limit of 90%.

Manually setting PPT TDC EDC to stock values didn't do the trick alone

Ah right, I missed that point. Sorry.

That is weird. Glad that you appear to be sorted.

AMD can be a pain at times and their BIOS can often need careful tweaking.

I had an issue ages ago where I needed to manually set the SOC voltage to 1.1v or the system wasn’t stable.

The ASUS BIOS just wasn’t doing its job properly.

That being said, once I manually set a lot of voltages and updated the chipset drivers, I’ve not had any issues since.
