So, Europe, late 2025.

As i said, seems to be a cost reduction of the known design. Plausible. Thank you for sharing this information.

Until we have more information, RebelsTool won't be able to help with your power limits. I am sorry, can't give you any time frame when this would change.

Das nehme ich als Grund, komplett auf Linux umzusteigen, wo mir "lact" 375 W ermöglicht und die Karte auf das Niveau ihrer größeren Schwestern bringt.

 

[hellm]

Yes, linux has more possibilities, as you can overwrite at least the open source part. I don't know if the SMU mailboxes aren't secured there, i highly assume that they are.

So, whatever LACT may give you as maximum, without tinkering with the amdgpu module, should be the same as +10% power limit in Windows. I suppose your card has 340W stock limit?

 

[Timpa]

the card on windows therefore from bios has 304+10%pl, in lact I can get up to 375

Interesting.. this is some number LACT came up with, or does it seem plausible due to other stuff, like real measurement of the cards power consumption or at least some benchmark scores.

As a softworker, i now one thing: never trust software. Not even your own.

Of course, hardmods also work. On my GeForce i simply soldered another shunt resistor in parallel, and now i have ~380W limit instead of 305W. Works also on Radeons, since the power signals from the controllers are somewhat tangled to the measurement on the shunts. Curent limit, though, not so much, but it is recommended only to go beyond this limit with proper water cooling.
So, 400W or something is totally doable. You would lose warranty, if you care about that.
