Picture of Edge Connectors (full size)
I think this article needs a picture of closeups of edge connectors. Preferably all sizes to complement the picture of the slots. 123.243.109.192 (talk) 03:43, 13 January 2013 (UTC)
- I don't know what you mean by "edge connectors", but if you mean it needs one or more images of the actual PCIe x1 and PCEe x16 slots (like this), then I absolutely agree with you. Right now the only three pictures in the article are of MiniPCI and MiniPCI Express cards. --82.170.113.123 (talk) 17:41, 25 March 2013 (UTC)
use of SMBus at PCI Express add-in cards
On what kind of real existing PCI(e) add-in cards are SMBus-Devices implemented and with what kind of functionality is the SMBus used on this PCI(e) add-in cards? Erik--87.158.143.13 (talk) 20:24, 25 February 2013 (UTC)
PCI Express config space
Should the PCI Express config space link be removed? It is broken and essentially addressed by the PCI config space link.

- PCIe uses the same (software) configuration mechanism as PCI, so the config space isn't much different (if any). Zac67 (talk) 20:04, 18 March 2013 (UTC)
- Thanks! The config space link is less confusing now. Spinlock55 (talk) 16:12, 22 March 2013 (UTC)
copper vs fiber-optic latency
"Certain data-center applications (such as large computer clusters) require the use of fiber-optic interconnects due to the distance and latency limitations inherent in copper cabling."
'latency limitations inherent in copper cabling'
http://answers.yahoo.com/question/index?qid=20080822183553AAqkj9m http://physics.stackexchange.com/questions/2537/physically-induced-latency-in-internet-connections
These links suggest that the commonly used fiber is slower, but recently there has been development of hollow/empty core fiber which is faster, so certainly some financial trade related data centers and cables could be using it already.

Mini PCI Express Pinout
The pinout for the Mini PCI Express connector is listed on the German language version of the Mini PCI Express page (http://de.wiki.x.io/wiki/Mini_PCI_Express). I'm not comfortable editing this page directly, and I cannot verify the information listed on the German page, however I think it would be ideal to either move Mini PCI to it's own page as it is on the German site, or to at least list the pinout here.

Differential Signalling
The text of the article says that differential signalling is used, but the pinouts mark one conductor of each pair as 0V reference and the other as signal. One or the other must be wrong. Which? GoldenRing (talk) 10:00, 5 August 2013 (UTC)
Too much information about the old PCI?
I just wonder if this article talks way too much about the old PCI. Probably better to isolate the comparison between PCIe and PCI to one section only. — Preceding unsigned comment added by 85.23.88.39 (talk) 16:51, 18 September 2013 (UTC)
