Comments (eg: how has the eGPU improved your workflow or gamin

Hey guys i recently ordered a eGPU dock but whatever I try to do it only using 2 PCIe lanes.

Do you think there is way to force it to use all 4 lanes?

@kunal_ralhan, welcome aboard.

Based on  https://youtu.be/watch?v=vEVjYTWcYMo [ASUS ROG Strix G15 G513 - disassembly and upgrade options ], your laptop has 2 x M.2 NVMe SSD slots.

May I ask, have you tried switching your M.2 NVMe eGPU to use the other slot to see if get a PCIe 3.0 x4 link instead?

Some manufacturers will may electrically or BIOS limit secondary M.2 slots to lower 2-lanes due to platform limitations.

If that primary M.2 NVMe SSD slot, which should be 4-lane for highest storage performance, still sees a M.2 NVMe eGPU link at 2-lane, then it would suggest the BIOS downgrades the PCIe link when detecting a non-SSD device attached to that slot.

@nando4,  hey thanks for welcoming me on board in this great community.

Yes i did tried switching the nvme slot to second one but still the same issue i face only getting 2 lanes active.

If its a bios issue do u think that there will be any workaround?

Link lane width is, at least on Intel CPUs, controlled by BIOS bootstraps requiring a BIOS mod to alter it's vendor set behaviour.

Can refer to my HP ZBook Studio G5 signature link where it refers to a Fuss-Free Bootup (FFB) to see an example of some techniques to wrestle with the BIOS to try to get the eGPU working.

Not sure if your F43SG has it but a K43SG/R43SG has a BIOS-defeating switches PERST & CLKRUN# to try to hide the eGPU from the system during cold bootup. They are a good start.

Other techniques may be testing if a sleep/resume changes link width as well as a warm reboot (inc testing with FastBoot enabled/disabled).

Lastly, could unplug a PCIe plug from your GPU during bootup to see if that changes things.

Could boot Ubuntu Linux Live USB stick to see if it somehow manages to get a x4 link for your eGPU after BIOS bootup which could then see if can replicate pre-Windows OS boot using UEFI shell and a UEFI Bootloader.

Yes, it's trying to find a magic pathway unique to your gear to bypass the cold boot setting a x2 link for that PCIe link when not detecting a SSD attached during a cold boot.

laptop display not recognised while using output from eGPU

i tried alot but when ever i try to take display from eGPU on my laptop display stop working like windows can even recognise it

and also my amd igpu stop working as well showing code 43 in device manager 

is there a way that i can take output from eGPU and still use laptop display doesn't matter if igpu is display outputting laptop display i want both display to work

@kunal_ralhan, you're earlier screenshot showed the iGPU + dGPU + eGPU as active in Device Manager.

If the iGPU, that drives the laptop's LCD has an error 43 against it preventing it's functionality, then eGPU accelerated internal LCD will no longer function.

I'd consider DDUing all AMD + Nvidia drivers in Safe mode to see if can get the iGPU all active again.

Furthermore, have merged your topic into build template form to appear in the BUILDS area of the site.

Pls consider completing missing sections and expanding others to form a comprehensive build of what was required to get your eGPU going on your notebook and what performance you are seeing from it.
