2015 15" Lenovo G50-80 [5th,2C,U] + GTX 970 @ 4Gbps-M2 (EXP GDC 8.5D) + Win7 [Ricardas Muzikevicius]
Lenovo G50-80 15inch, Intel core i3 5005u @2Ghz, Intel HD graphics 5500, 8Gb RAM Windows 7.
I have installed m.2(NGFF) card from exp gdc to my wifi slot, connected power cables for NVIDIA card, plugged in HDMI dummy to hdmi port in graphics card. After drivers installed, my pc detected GTX 970 then in screen resolution settings i selected extend displays. No bios mods or editing nvidia drivers needed in windows 7. So when i dont need power laptop uses intel hd graphics, and when i start benchmark or game laptop uses GTX 970. The performance of laptop in gaming and benchmarking significantly improved.
Some results after upgrade from GTX 660 to GTX 970 using Unigine Heaven:
Is the hdmi dummy necessary?
My BIOS is updated tho. My “Lenovo” logo in disrupted pink light painting. Ugh.
Will the HDMI dummy save me from this torment? Because my GPU is not detected on device manager no matter what I do.
I disabled the m330, or the dGPU pcie, or by using UMA setting, or disabling PXE boot to lan etc. Fiddling the ATX ON/OFF and PTD delay 7s/15s etc.
While in UMA tho laptop got stuck on that Lenovo logo. On discrete got a black sceen.
Tried connecting HDMI from laptop HDMI output, No Signal. Tried HDMI from GPU HDMI output via UMA setting. Signals the fancy logo from Lenovo but stuck. External and internal monitors nothing works.
I also tried hotswapping the wifi card to the NGFF cable once but I almost electricuted myself.
How could you even install the drivers if the hardware is not detected?
Hope you could help me, I’m in the brink of losing hope.
