Having separate channels for egpu input and output on laptops with two PCIe x4 slots
I am new over here so don't know whether this question has been asked already or not, so please bear with me.
I have two unpopulated PCIe x4 slots in my laptop. It's is an Aorus X5 V6 if you are wondering.
I have read an article on I think ars technicia where they use a GTX 1080, 32 gigs of ram and a i7 6700k on different configurations of the PCIe slot and show the difference of performance across 20 games. On a x4 Gen 3 through chipset config, the average drop in performance is around 5 to 10 percent of a x16 Gen 3 config. The performance difference between x8 and x16 in Gen 3 is practically 0.
Is there any way that input and output streams of the gpu can be separated and diverted through the two x4 slots?
This could empirically create an x8 slot and possibly make laptops and machines like these more future proof with the ability of adding a gpu 3, 4 maybe 5 years down the line.
Or am I tripping balls and this is not possible at all?
And does anyone know a guide to overclock and undervolt the cpu(i7 6820hk) and gpu(GTX 1070 non max q) on a laptop with a locked bios?
If you can do so yourself please send me a PM.
