Shunt mod obviously works, because i have a AX860i PSU with Power monitoring and the power draw is ~50W higher now running 1924/1949MHz in Furmark instead of 1800-1860MHz before.
Actually when i did the shunt mod i had the Strix BIOS loaded in it and i have seen the same behavior in MSI AB and GPU-Z, but the power draw was the same, simply like if the shunt mod wasn't working and as i suspected flashing back stock BIOS solved the issue and made shunt mod working, so obviously Strix BIOS and Stock FE BIOS are handling power management differently, maybe it has something to do with the fact that i didn't put CLU on the PCIE shunt?
It's better you didn't put it on the pci-e one, safer. Shouldn't draw more from the board itself.
Although did you measure your resistors with a multimeter? I read its recommended to measure them to see if you put enough clu or not.

You'll never get a sustained 120% unless you can find a stress test that pulls that kind of load and I haven't found one that does yet.
I DID hit 120%+ off and on regularly running the custom TimeSpy, it jumps all over the place though.
So is that not similar to when you hit 330 watts on the stock BIOS then? Because it does happen occasionally on the stock BIOS.

Note to get anywhere near FE bios I added +100 more to the mem clk, Asus doesn't power limit as much but I'm still hitting it around 111% even if it can spike past to 114%
2138 although I think it was going as high as 2152
115% and massively power limited
Asus clks higher or I should say further than FE, curve would be similar but the little extra power allows it to use a few more bins, performance for me at least is not as good as FE and I feel that's because they soften some settings to allow for bigger clks on core and mem that take more voltage and power but probably end up at a similar result with tweaking.
26c temps are full titan block on chilled water cooler system. curve is defaulted, then raise,
1.000 - 2075
1.011 - 2075
1.025 - 2088
1.031 - 2088
1.043 - 2101
then flat at 2101
just see if you drop lower than 2075 in my case, and if so raise the next voltage down to minimize the loss.
Hopefully the shunt mod works, or we get a full unlocked Asus bios, I could work with that
Looks like your Asus bios results are worse than FE, similar to everyone else's experience, besides KedarWolf.
Truth be told, when we're power limited we're running the core in a gimped state. Who knows if you can truly hold 2138-2152 Mhz on a shunt mod. This is evident when you compare our scores to users without power limiting, them at 2050 Mhz is like us power limited to occasionally hitting 2101 Mhz.
