    Have you given it a whirl?

    "Improved fan rotation speed control." ..... wonder what exactly that means on this release.

    Can you run this command in Powershell on your computer?
    (just copy and paste the whole thing in PowerShell -> right click in the window will paste, then hit enter until it processes)

    Code:
    $buses = gwmi Win32_Bus
    
     foreach ($bus in $buses)
     {
     $id = $bus.DeviceID
     gwmi -query "associators of {\\.\root\CIMV2:Win32_Bus.DeviceID=`"$id`"}" | format-table Name
     } 
    Then reply to this thread with the output under PCI bus? Should be the last section.

    I had to search to find out what that means. Top Of Low Usable DRAM. Does this imply the usable RAM in 32-bit configurations?

    I am also curious, because if it's 3GB, what's the issue with the PCIexpress vidock mod? Why does that cause such a headache with 3.5gb of TOLUD?

    TOLUD is where system memory and device addressable space split. If it is 3GB then a 32BIT system maxes at 3GB of 4GB (as 4GB is the total for 32bit) and the last 1GB is all for device address space (i.e. PCIe bus and such).

    If it is 3.5GB then only 512MB is available for devices. Because you already have a GPU in the system and a bunch of other devices, that doesn't leave enough address space for the eGPU. The only way to make sure it has address space is to force the system into 3GB of RAM (so only 3GB total for the laptop) so the last 1GB is for devices.

    EDIT: I'm sure Nando4 or someone else can explain it better than me.

    "Fixed an issue where system performance might be down in high stress
    configuration."

    Is this a further improvement on the earlier throttling condition/

    I updated a few days ago to 1.22.

    No problems to report so far.
