TDP lower to 7800W and PPT reduced to 3d.
I'm working on reducing the power consumption of the 7800x3d. So far, eco mode maintains around 88-90W under full load and still hits 82-83°C with my AK620. I'd like it to operate closer to 65W-70W or even lower, without worrying about peak performance times. For gaming sessions I don't notice it exceeding 60°C (last of us part 1, new world, black desert online, etc.), which is acceptable. Cinebench shows all cores running at 4900MHz and low frequencies in the 80s, that's what I'm aiming for. I've adjusted my fan settings but haven't seen much improvement. Any suggestions on optimizing it further? I'm currently using an EXPO profile (maximum SoC voltage 1.250 with BIOS EXPO) and a PBO negative offset of -30, but temperatures remain unchanged. I'm considering the ASRock B650E Steel Legend.
still no reason to do so With such low voltages the things already running at you can go and run at tjmax for decades and itll still be fine All you are doing is nuking cpu performance with absolutely no noticable benifit But if you wanna go ahead anyways i guess you could just set the powerlimit lower, retarded amd doesnt allow manual multiplier adjustment on x3d and you are not using a board that has asynchronous eclk so have fun trying to optimize both performance and power draw when you have half the tools needed
It's still a solid reason to do so. I'd rather keep the CPU operating at lower power consumption rather than reducing fan speeds and letting the chip throttle itself. I recall seeing guidance on specific wattage limits—like 45W, 65W, 90W, and 105W—along with their corresponding PPT, TDC, and EDC values.
Increasing fan rotation won't make much difference because the heat isn't leaving the CPU properly. Just set the fans to their highest speed you can hear without noticing. It doesn't seem like the chips are throttling much at 83°C, so let them run as fast as possible up to the maximum supported temperature (like around 90°C for X3D).
Goal achieved to reduce TDP. Successfully managed power usage at 75W, cutting CPU temps by nearly 20°C compared to full load. Previously, fans at 40% would push temps up to 88-90°C. Cinebench R23 performance remains stable. For the ASRock B650E, configuration is: Advanced > AMD CBS > SMU > PPT in mW set to 75000.
