I'm posting today because HP actually impressed me with the cooling performance of this laptop. I'm maxing out temps at 70c on both the CPU and GPU in hard to run titles like Expedition 33 and Borderlands 4. However, I wish I could run the GPU at a higher power level.
HP implemented a 110W TPP for the entire laptop. This means despite me having enabled unleashed mode, turned up the power limit, turned up the battery max draw, turned up the chassis temp limit, the 5070 will not consume more than 80w.
This is handicapping the 5070 a lot, I am power limited 100% of the time as reported by afterburner/gpu-z. The laptop ships with a 150w adapter which does fail to keep up surprisingly but it doesn't draw down too badly. (Please stop doing this HP, include the 230w adapter next time). I also have stronger power supplies available that work with this laptop. I really wish I could get the GPU to consume like 100w, since it caps at 70c currently with no cooling pad. If I try to load a non-HP vBIOS the card is not recognized by the system, I assume due to the embedded controller HP uses. The 5070 continues to scale well up to 110W so its just forced to give up a lot of performance left on the table as it is.
I have 2 requests henceforth:
1. HP, please allow the GPU to pull up to 100w so the 5070 isn't being dragged down so badly, you already include a battery draw down slider for this since you cheaped out on the power supply.
2. Anyone have a vbios from the Non-slim HP Omen 16 with 5070, or the Omen 16 Max with 5070, that can send it to me or upload to tech power up's vga bios collection? Device/Hardware ID needs to be: 10DE 2D18

A further note on the power consumption of the GPU vs the power limit.
As it is, with +0 on the core and +0 memory, the memory often downclocks to 18gbps in games when the memory bus usage is relatively low. The memory will clock up to 24gbps max under highest load, with 22gbps being a mid point that is more often chosen. It's clear the card is doing this for power reasons.
I'm not sure if this is NVIDIA's power savings technique on mobile (Driver is set to max perf) or just the low power limit, but what I can say is that it seems like some of the power limit increase would just be allowing the memory to run at full speed nearly all the time, as desktop cards do. I can manually overclock the memory +1000 and it will basically do 24gbps instead of 22gbps or 18gbps, more of the time, but the core clocks lower because of that and the GPU is pinned at 80w more closely, but the temps and performance are the same.
I really think 100w would be feasible thermally speaking given the memory needs some of that headroom so its not forced into downclocking while gaming.
