Electrical signals travel at the speed of light for the current medium and wavelength. The "speed of electricity" term normally refers to the velocity of the actual charge carriers, e.g. electrons or ions, which travels many orders of magnitude slower than the electrical signal itself. The sentence in the "Serial bus" section should be reworked since as it is right now it is inaccurate and may be misleading to a reader without sufficient background in physics. —Preceding unsigned comment added by 91.66.18.56 (talk) 16:15, 6 November 2010 (UTC)[reply]

nVidia and PCIe

Why it is stated that nVidia supports PCIe v.2.0? None of nVidia chipsets fully support the standard (same for the graphics cards) - nVidia chipsets are somthing that Intel marks on its product PCIe v.2.0 (2.5GB/s) - might be a bit more. As to the graphics cards - they use "Graphics PCIe* - a propriatary and slower than v.1.1 version of PCIe —Preceding unsigned comment added by 78.36.39.135 (talk) 17:37, 11 September 2010 (UTC)[reply]

PS. Someone is persistently deletes any info about NVIDIA "Graphics PCIe" - seem to be NVIDIA-paid, as full info on non-standard NVIDIA PCIe interface (no parity and very slow, still in use up to Fermi processors) may be found in several Intel documents. Support of "Graphics PCIe" is specially noted in X48 and X58 chipsets docimentation. The problems with "Graphics PCIe" on PCIe v 1.0 slots - in several much ealier documents. The problems with standard PCIe 1.0 cards in ealier NVIDIA "PCIe" chipsets slots - in Areca, Adaptec, HighPoint documentation

Standard mini PCIe SSD

Can the editor or someone explain what the next sentece talks about?

"[...] there is a true 51mm Mini PCIe SSD with two stacked PCB layers, which allows for higher storage capacity. It preserves the PCIe interface, making it compatible with the standard mini PCIe slot [...]"

Nonstandard PCIe form factor

Does anybody have more info about PCI express cards which have the same connector as a Mini PCI type III (124 pins, legacy 32 bit PCI used for laptop Wifi) but they contain a PCI express interface? I have a SAS adapter made for IBM servers which is such a nonstandard card (lookup 44X0411 in Google / Google images). We tried it in a PCI to MiniPCI adapter - it of course haven't worked (we did not know it is PCI express at that time). So we were lucky that there was no smoke - but the card mechanically fits, which is quite an issue! Thanks for any info, Daniel. 95.105.164.207 (talk) 14:55, 16 August 2010 (UTC)[reply]

Compatibility

It is stated that PCIe 2.0 is backward compatible to PCIe 1.0, in most cards and in most motherboards. It is also stated that most new motherboards supports PCIe 2.0. However, I think the article is missing information about support between 2.1 and 2.0 (in both "directions"). --Petter, 130.236.60.26 (talk) 16:13, 14 September 2010 (UTC)[reply]

Backward compatibility of 3.0

3.0 slots are not backward-compatible. This ought to be mentioned, perhaps with an explanation from whoever made the decision to break compatibility. 98.235.81.240 (talk) 20:59, 21 November 2010 (UTC)[reply]
