PCI-e Link Width Tags: Graphics Cards PCI Express Graphics Last response: July 12, 2008 1:03 AM in Graphics & Displays Share Lord_Santa July 11, 2008 9:45:17 PM First of all, hi everyone Since I managed to screw up my first (detailed post) and never got it posted, here comes the short of the long. I am trying to make my PCI-e Link Width to be x16 instead of x4 as it is at the moment. I have been searching for the past 5 hours, through forums and the internet, to no avail Sure there are maaaaaaaany explanations out there, but none that I can comprehend. Can someone please tell me if there is an "easy" way of fixing this? (I am not afraid to mess with BIOS, etc.) My MB is a: 4CoreDual-VSTA My GraphicsCard is: Geforce 7950 GT OC And according to RivaTuner it does support up to x16 ANY help appreciated. Thanks in advance More about : pci link width cjl a b U Graphics card July 11, 2008 10:11:54 PM The graphics card is in the top slot, right? Often, the top spot is the only one that supports a full x16. spathotan July 11, 2008 10:15:07 PM That motherboard only supports PCIe at 4x speed max. This is due to it being a dual slotted board, it supports AGP as well. At 4x you might as well be running AGP, hell. http://www.asrock.com/mb/overview.asp?Model=4COREDUAL-V...
