Hi there,

Need some advice.

I have made a custom case for my mining rigs.
I would like to EXTEND my Pci-e16x slots, my motherboard has plenty of them.

I have tried extending them with these cables;

I've tried this solution but unfortunately it doesn't work.

Can somebody confirm that i can use Pcie1x->16x extenders on a 16x slot?

Thank you

A few things come to mind that mess people up populating cards on the 1x ports

First being short the pressence detect pins, to fool the slot to go active as if its a 16x or whatever X

Second being some older bios only have so much bandwidth, and you have to down clock the bandwidth on the pci-e slots to distribute the bandwidth across all slots..  this one is RARELY the case..

I personally am using a ebay china adaptor, 1x to 16x ..

I had to make NO changes to get it to work.. it simply just worked..

From a native x16 slot you need an x16->x16 cable.

From a native motherboard x1 slot, you can use the x1->x16 adapter cable.
