Closed How to tell how many PCI-E lanes? Tags: Graphics Cards PCI Express Graphics Last response: May 27, 2012 8:44 PM in Graphics & Displays Share WyomingKnott May 27, 2012 12:10:04 AM I had to put my graphics card into the second slot in my Asus P7P55D Deluxe. The fanless cooler conflicts with my CPU cooler when it's in the first slot. Is there a way to tell how many lanes are actually available to it in that slot? The manual doesn't mention what happens with a single card in any slot other than the first. The card is a Sapphire Radeon HD 3650 512MB DDR2. Okay, it's not the fastest and it probably can't max out 8 lanes, but it's silent.

Anyways, make sure you enable the little test in GPU-z that gets your graphics card working so that it reports the lane speed correctly.
