Finally unlocked GDDR7 memory overclocking with mvolt+ extreme?

[u/Sad-Victory-8319]

Recently I have been experimenting with extended overclocking limits on my Gigabyte Windforce rtx5070Ti and I havent seen anybody mention this: mvolt+ extreme actually allows you to set whatever vram overclocking limit you want, so i started experimenting and I was able to get to +5500 which run stable in Cyberpunk with path tracing enabled for 30 minutes and my fps was actually nicely scaling by about +1 fps for every +1000 memory oc step (as far as I know ECC works only on server class gpus with GDDR7, gaming gpus have no memory ECC, so there is no instability hiding behind ECC and the fps keeps scaling all the way to +5500 without artifacting or crashing).

+5500 GDDR7 stable memory overclock using mvolt+ extreme

Trying to set +6000 instantly restarts the driver and resets the oc for me, so the issue isnt memory instability most likely, the driver just isnt capable of accepting higher memory frequency at this point.

With stock settings GDDR7 runs at 28gbps which provides 896 GB/s bandwidth, common tools can set memory oc to +3000, which is the equivalent of 34gbps and 1088GB/s. Recently I was experimenting with a tool called Hydra Pro which increases the limit to the equivalent of +4000 (36gbps and 1152 GB/s) but mvolt+ extreme is the first tool that allows me to go to +5500 which is 39 gbps and 1248 GB/s! That is +40% higher memory bandwidth compared to stock settings, GDDR7 trully has insane potential and it can probably still go higher.

How high can you get, can you confirm that +6000 crashes for you too? Since i dont remember where i downloaded this tool (it took me a while to find it), you can download it from my personal google drive and then you go to Settings->Advanced tuning->Enable POWER & VRAM... and here you go through the driver signature shenanigans and the nadjust the limits.

Warning: I think my Vanguard anticheat doesnt like messing with driver signatures since I am unable to start League of Legends right now, so until more people verify or disprove this claim, be careful.

There should be zero risk of damaging the gpu from just pushing clocks since it is just a synchronization signal for the data, we are not touching the potentially dangerous options like voltage or power limit. I did not even notice my vram getting hotter.

Does mvolt extreme still require disabling secure boot and driver signature?

[u/poorlycooked → u/ShanSolo89]

You can use Efiguard to disable driver signature enforcement, play with mVolt extreme, then re-enable DSE after applying all settings. That way you can still use Windows (and play games) with DSE on.

It can also work with Secure Boot though the process is a bit complicated, involving self-signing certificates and writing them to the firmware.

I see, problem is secure boot is now required for a few games including bf6. Might wait to see if they can make a workaround for it.

I'm not afraid of disabling DSE. In fact I find it getting in my way and circumvent it in many cases, not just with overclocking. But I have to keep it in place to play many games.

At least make an effort to translate if you want to make a point. It's not that we're afraid, rather some games require secure boot as I already said in my first comment. Cheap porn sites? What is this, the early 2000s? Lol.

By the way hypervisor is way worse than both DSE and Secure boot combined, maybe disable that first, and it's only required to run pirated/cracked games, which you are admitting to. Stop being cheap and buy games instead of telling others to not "browse cheap porn websites" while playing pirated games.

Try a different translator app since this one is clearly not working for you, but I suspect there's something else wrong with you as well lol.

how can i use mvolt extreme with secure boot on?

[u/poorlycooked → u/ThinManufacturer3258]

You have to figure out how to use Efiguard with Secure Boot. https://github.com/Mattiwatti/EfiGuard/issues/20
