[SOLVED] VRAM overclock @ RTX 3070 >> Safe?

Hello,



I see many RTX 3070 owners OC VRAM from 7000Mhz to 8000-8400Mhz and call it "Very safe, worst case, it will slow down due to error correction, then you simply under clock it".



How much truth to that? really no damage?



Secondly, boosting RTX 3070 up to 2077Mhz, considered safe? if I do not increase Voltage.



Only thing I did increase: Power Limit to 113%.



Palit 3070 GamingPro Edition



Your professional input appreciated,



Thanks!

I would leave Vram OC'ing alone.
It's just not as forgiving when things do go wrong, and the gpu will last longer - you know, for if you want to sell it off later, or maybe hand it down to a relative/friend?

Error correction is not foolproof(failproof?). I wouldn't put all my trust in that, except if it were ECC ram, which it isn't.
"Very safe, worst case, it will slow down due to error correction, then you simply under clock it".
By the time you get your first symptoms that the OC that was stable is no longer, it's already too late, and you delay the inevitable downclocking and making it slower.
Plus, the voltage sent to the Vram is fixed from bios - gpu undervolting does not affect it; at least if cpu and gpu core OC's aren't...

Plus, the voltage sent to the Vram is fixed from bios - gpu undervolting does not affect it; at least if cpu and gpu core OC's aren't stable you can both lower the clock and voltage.
Whereas if it was left alone...

It was designed to do that - pursue higher clocks as long as it's parameters were acceptable.
So yes, it's safe.

No OC'ing is without its risks, but ram isn't as forgiving when you screw up.
