  1. It just get weirder..... Furmark screens below. Low FPS on AC power High FPS on Battery Back to low fps when plugged back in to AC power again?? I don't get it Screen shots in order: on AC (after cold boot), on battery & lastly back on AC.
  2. Yep, all drivers are up to date, latest BIOS, latest intel drivers, latest Nvidia driver (used DDU to clean install) Here's a screen shot of Hwinfo First image is low power / low fps after a cold boot Second is after doing the unplug / re-plug of the AC adapter. 3 x more FPS after doing the AC adapter dance!!
  3. Howdy all, longtime lurker - first post Briefly, the machine has an i7-8750H & GTX 1050 4gb (non TI), 2 x 1tb ssd's, 32gb ram. All drivers are up to date & system bios is also the latest (F10.A). There's a weird power switching issue going on that I can't seem to find the source of..... Sorry for the long post below haha. With the machine on mains power, from the initial cold boot, the CPU runs fine (undervolted & running 45-60w @ 95c under benchmark loads). The problem is the nvidia GPU, with the machine in the same state after a cold boot, running any Performance test 10.0 GPU benchmark results in super low FPS - see below. From cold boot - AC adapter plugged in DX10: 10-12 fps DX11: 20-25 fps DX12: 14 fps Logging shows GPU core v .715 v, Clock 1000mhz. Just horrible!! But here's kicker #1, if I unplug the charger from the laptop for a couple of seconds after the system has booted to the desktop, plug it back in & rerun the same benchmarks..... DX10: 49 fps DX11: 80 fps DX12: 50fps Logging: GPU core .811v , Clock 1354mhz. Kicker #2: Over clocking the GPU..... Gpu core .950v, Clock 1825mhz, mem 4000mhz DX10: 65 fps DX11: 105fps DX12: 72 fps Unplugging the charger (momentarily) puts the GPU into a higher power state – but WHY?? The exact opposite happens with the CPU – high power state on initial boot (45-60w under full load). Unplugging the AC adapter & plugging it back in again results in the CPU power being limited to 20W (showing as PL2 limit in throttlestop) only shutting down & re-booting the system will restore the CPU back to it's full power state. I'd appreciate some input to get my head around this behavior & see if there is a way around it? It isn't being caused by windows Power Plans changing & not changing back - I've even set up another power profile with all power saving disabled & there's no change. The screen shot below shows Cinebench R20 results & the performance difference between 'normal' 2734 @ full power & the drop to 1672 @ 20W. (Both runs are with the ac adapter plugged in - but the low score is after unplugging the adapter for 5 seconds & plugging it back in prior to re-running the bench mark)
