Well, on up-to-date BIOS (BIOS 1.28) my E480 with i7 8550U and RX550 achieved (CPU undervolt proportional -0.108V, no thermal paste replacement/upgrade) in 3Dmark 11:
run 1: 4 771 (3Dmark11 result no 13175941) (Windows 10, power setting "Balanced, Best performance")
run 2: 4 746 (3Dmark11 result no 13175982) (Windows 10, power setting "High performance" [keeps CPU freq on max Turbo Boost even when idling, but probably decreases GPU thermal performance that way or maybe the laptop was just still warm, accumulated heat], TPFanControl with custom "smart 1" mode that goes to "64" fan level when CPU reaches that is faster than BIOS goes up to, judging by ear)
Normal hardware/BIOS fan control is also fixed and rational: lets the CPU achieve normal working temperatures like 45degC up to 50/48 maybe without turning on at all while doing web-browsing and other CPU non-intensive tasks in "Balanced, Better performance" Windows power-management mode (which is most of the time), unless you disable Radeon GPU which causes this embedded fan management algo to go crazy and try to keep your CPU under 40 degC quite aggressively.
Hi man, I'm also undervolting my machine. I use an offset of -0.105 in both cpu core and cache. I'm using Balanced, which alternates from Balanced [Better Performance] (on battery) to Balanced [Best Performance] (when it's plugged in). As of my tests, I couldn't see any difference between High Performance and Balanced [Best Performance], while plugged in. High Performance runs always at full speed regardless you're plugged in or not. Balanced otherwise automatically change modes depending on your energy mode.
About the fan, do you think it run faster with TPFanControl? Can this software help on lowering temperatures or just manages when the system kicks in the fan?
Last but not least, I see you're running bios 1.28. I'm still on 1.13 because of the agressive dGPU throttling Lenovo introduced on 1.14. How is your experience with the latest bios? Do you see any throtting on the RX550? The last time I tested on bios 1.24 it was still there... gpu clock goes from 900mhz to 200mhz after a few minutes of gameplay.
Hi again,
I haven't tried playing any games yet, but this 3Dmark11 test takes quite a while and I think the results are comparable to the reviewed unit with BIOS < 1.13?
Regarding TPFanControl: yes, it is just a custom way to control the fan speed, but you can set your own "smart 1" (which can be active by default) and "smart 2" profiles in the INI file (I can provide my presets if you want, but would probably be best to work out what you prefer) and you can make some profile(s) that are more aggresive than the default stock BIOS behavior, and that way you can improve under-load performance.
In practice, I only run TPFanControl with aggresive fan profile when I need to do some longer, processing-intensive tasks.
