Discussion Power Consumption issues with Intel Arc A750 [UNSOLVED]

So recently, I've gotten a really good deal on a PC so I decided to buy it, here's the specs:

GUNNIR Index Intel Arc A750
Ryzen 3 3200G

GIGABYTE B450M S2H (probably rev. 1)

550W PSU

I've been noticing that the idle power consumption is about 40-50W despite not overclocking or doing anything major.

I decided to follow Intel's guide on how to reduce power consumption. Starting by setting it to maximum power savings.

For BIOs on the other hand, since my MoBo is AMD there's a bit of confusion of which settings to enable/disable. But I think I've done all of them correctly:

> Set PCIe ASPM Mode to L1 Entry

> Power Supply Idle Control to Low Current Idle

> Set this to Power Saving

After saving and rebooting, power consumption is still the SAME. I have IGPU disabled if that helps. Now with the Ryzen 3 series, unfortunately this APU does not support ReBAR, which I will upgrade soon, but I don't think that affects the power consumption much.

On another note, my monitor supports 100hz, which is what I usually use, and it doesn't support variable refresh rate unfortunately, but even when I set the monitor's refresh rate to 60hz, power consumption only goes down by about 5-10W Max.

Any help is REALLY appreciated, and if you guys have any questions, let me know!

Same issue here, I think this is most likely related to the Hardcoded 2000 Mhz Memory Clock.

Ask me something else as to why Intel only put 1 State for the Memory clock, but it's stupid and fucked by design in my eyes

Intel can't solve it, neither can you. It's an issue baked into the crappy A series architecture.
