Gpu problem

[storm05]

I have tried to do a undervolt on my Rtx 4070 exactly the same way as in the tech yes city yt video but every time I do the undervolt or less of an undervolt my game instantly crashes when I apply it. It can't even do 1000mz on the memory because bo6 might crash and the crash report blames it on a gpu overclock. And some times when I play bob part of the screen flashes green or some other colour for a split second. Is there something wrong with my gpu?

Specs:

15 12600k 32gb Rtx 4070 windforce

3x Asrock b660M-itx/ac 750w

btw I don’t need the undervolt since the temps are really good but this issue concerns me, I can return it if needed

First thing, forget about overclocking the VRam for now.

I'd try : reset settings in Afterburner, check if you've still got green flashes,

Did you try higher than 0.910V at 2700MHz ? say 0.950V ?

Could you take a screenshot of your curve.

Could you try a safer setting of 2500MHz at 0.930V with keeping the beginning of the curve not above the original value (1700MHz)
