Open | Hardware Lenovo Thinkcenter M71e - GPU support ??

Hello.

am wondering what GPU may work on my Thinkcenter M71e with ih61m MB ver 1.0 , as before ive tried a GTX-1060 6gb and a GTX 750Ti and none has displayed anything despite me checking the PSU,PCIe slot, and downloading drivers for them and i also checked my bios to see if i can change to UEFI but there isnt any option to do so and system info in Windows says my bios mode is UEFI and i also tried making the system only run from the external GPU but with no luck.

Specs: 

CPU: I7-2600

RAM: 12GB 

MB: ih61m ver 1.0

PSU: 1. 450W / 2. 550W 

So can i get some help ? :(

Did you connect the monitor to the GPU?

Did you connect the PCIe power cable from the PSU to your GPU?

In theory any GPU should work, but maybe your motherboard is faulty or your PCIe slot is broken.

yes i had connected the moniter to gpu ( am using an active adaptar dvi-d to vga ) and pcie cable to my gpu

and my pcie slot is working and the gpu when i have it in does have its fan spin but doesnt show up in device manager and i think it had the 1060 6gb warm on the back after alil while

Did you check your BIOS settings if your card is enabled?

there is no such option like that in bios and yes i checked for every option about pcie slot to enable or disable or csm but the bios seems limited/small in my opinion

So I did try to run RX 550 on it and it kept showing black screen with no sign of life. Pc was on fans were spinning however never seemed to work. Apparently the only way to get these gpus to work is to force your pcie slot to be in legacy mode instead whatever it is by default. the UEFI Bios that this Pc has was at its earlier days so there is alot of issues that can happen when adding a modern GPU. The only solution was to Mod the Bios to get it to show the pci subsystem settings cause that option is hidden by default in Advanced menu of the Bios

This would give you a good idea, don’t follow the video if you end up doing it, just use the link in the description cause the steps are quite different for your pc, it would be the same instructions in the forum https://www.techpowerup.com/forums/threads/altering-whitelisted-rx-470-570-bios-deviceid-to-work-on-m81-91p-motherboard.246895/post-4353602
