- XPS 13 9360
- UHD 620
you were getting 5500/17500 in clover in MacOS? wow I only have seen those scores in linux. I will gladly share my OC folder as soon as I get back home. reminder, I'm using dell Inspiron and not XPS9360. also my power limit is set to 44w. not sure how you achieved 28w, but that could possibly be an issue. don't quote me on that since I really don't know.
@jkbuha could you tell me how to remove the acidanthera from motherboard and bios please?
Not sure I understand the acidanthera bit. Could you explain exactly what you want to achieve here?
With regards to TDP, I strongly suspect the Inspiron has better cooling techniques than the 9360.
This is a bit offtopic, but the best performance scores on the 9360 (7th and 8th gen) are obtained with the following:
1) Removing the heatsink, cleaning the thermal gunk that's gathered on the CPU/GPU, and replacing it with arctic thermal pads with 1.5mm thickness. The net effect is that the bottom lid becomes a heatsink, but the CPU cooling is phenomenal.
2) Undervolting CPU/GPU/Cache/SystemIO etc using setup_var and/or voltageshift. This is highly processor specific, though you should at least get -50mV (~4-6C) across all chips. The 8th gen can be better undervolted, I'm on -150mV at the moment.
3) Raising the TDP threshold, using setup_var. There are a few combinations that need to be applied, such as unlocking CFG, unlocking TDP_lock, and a few other tricks. They're explained reasonably well elsewhere, but if there's any interest on this forum I could put a rough guide together. However I've found that a stable balance is 28W, as with 44W there's too much up/down clocking leading to a drop in performance. It's worth exploring this again though, and I'll do that once I have an updated OpenCore baseline on which to run tests.
4) Unlocking the 4x PCIe lanes for faster memory and SDD/NVMe throughput. I've explained how to do this a couple pages back, it's a bit risky as you need to use a programmer (and the BIOS chip on this laptop is incredibly difficult to attach to) but there's a significant boost. However, there is a slight hike in temperature, which in reality might also lead to the TDP limits explained in 3).
With regards to overclocking, I recall that the U-series chipsets have their max multiplier locked, so I don't think it's possible to unlock. But if anyone has any additional info on this please get in touch.
