Lenovo b590 ram driver#
As said above, the eGPU driver should be turned off, to once booted into Windows (if successful), enable the eGPU driver. Find the chipset memory or memory section to get maximum RAM information. The user guide can be found by searching for the product name at Check the Specifications tab in PSREF after typing the model name. Personally, the 56.12GB - 36-bit compaction worked for me (chose all PCI devices, force 32-bit upon eGPU). Search the manual for memory, maximum supported RAM, memory module, or soldered. If lower than 256 MB, perform PCI compaction (I am not sure which one would work, check setup FAQ for that).

Take note of how much TOLUD you have and how much free space you have. Once booted into Windows, enable the drivers.ĥ.2 Reboot with the eGPU connected to your PC and boot to setup 1.3.

Once the drivers are installed and the eGPU is detected fully (doesnt matter if its wokring correctly or with errors, such as 12 or 42, 43), disable the driver and try each method below until something works:ĥ.1 Reboot with the eGPU connected to your PC and the drivers disabled. If so, it should automatically start installing the missing drivers on its own. So check the device manager if the eGPU is detected. Once booted, the eGPU will not work, because there are no drivers, right? Right. Now, there is chance that this method could work, but only if the booting is successful, when the drivers are uninstalled. Uninstall the eGPU drivers (via show hidden devices in device manager you can keep the installation files) This method requiers you having setup 1.3, which provides the mentioned compation and also dGPU disable-type functions, which may also help.Īs I understand, Windows has the eGPU graphics drivers installed, right?īoot to windows without the eGPU connected I believe the same soliution might work for you (or any other PCI compation) (btw, I did this without DSDT override). Aparently, this free'd up 512 MB of PCI space on my laptop = eGPU success. Just yesterday, Ive solved my problems compating my PCI devices to 36-bit space and forcing my eGPU to a 32-bit space. I think the same is happening here with your PC. During my tests, I've noticed, that when with 2GB ram, the TOLUD value lowers, somehow freeing up much much more space for other PCI devices (went from 256 MB to 1 GB free PCI space).

Personally, I havent had any experience with eGPU vs dGPU situations, you should look up this forum or other places for the solutions.īTW, if you noticed, I have been ranting here about my problems with 2GB ram issues (that my eGPU works with 2GB and I also want 8GB). Well, the problem might be that there might be no space left for the eGPU.
