I install motherboards in old pcs and new pcs...

I just cant justify anyone using pci express x1 cards.....

( the little connector in the expansion slots )

I have got my self 2 tv tuner cards just to justify myself that pci x 1x actually does something usefull over pci.....

made by pinnacle

But there aint many more uses for it, is there ?

no x1 video cards, and the rest are hard to get hold off

Just wanna know your comments..

PCI express 16 - no problem

but pci express 1x - a duffer

Sound cards, RAID controllers, external E-SATA drive connectors...

Many manufacturers of these types of cards see no reason to move from PCI to PCI-E as the available bandwidth from PCI is sufficient.

just as i thought

none what so ever

if they want to dump the pci format in favour of pci express then the motherboard manufacturers will have to do more to move it along......

all of them seem to be chicken, by the looks of it....

ISA and PCI overlapped by 5 years or more while things were phased between them, I wouldn't expect this transition to take less time. It is all about legacy support, especially in the business arena. Hell it took more than a year just to get PCI-E graphics slots, let alone the smaller 1x and 4x on the common market.

The PCI-e x1 is the legacy version of the AMR riser slot found on older PCs. It's got a limited use and shares a lot in common. Truthfully, the slot has some high points, but many Mobo manufactures fail to create a 'slot easement' for this bus slot. Consequently, some of these X1 cards interfere with either North/Southbridge heatsinks or capacitors that are mounted directly in line with the x1 card. I'm wandering if many mobo manufacturers consider it as 'token' hardware, or unused/unneeded hardware.

They might as well kill PCIe x1 and use the connectors/lines,etc for some thing else like FireWire(?), don't know if it's possible though.

Ultimately a PCIe slot with any number of lanes is a PCI killer. PCI slots share bandwidth between them. 133Mbyte/s will be fine one active periphal/HD raid card but not 2+. Since PCIe 1x start at an aggregate bandwidth of 500Mbytes/s (250Mbytes bi-directional) which is serial point-to-point it is a much more powerful solution than the shared, parallel architecture of the PCI bus.

I like the fact that you can put smaller PCIe cards into multi-lane slots. Like I have a Firewire 800 controller which is 1x in a 4x (16x physical) lane PCIe slot. (Why?? Cause its a server board with only 1x PCI slot and lots of PCI-X slots)

The sooner PCI is killed off the better as far as I am concerned... Its like the ISA standard - a relic of yesteryear!!

Everytime I open a case to diagnose a problem and see an ISA port I shudder.

Everytime you open a case and see an ISA port, the bill for opening the case is likely more than the value of the computer :D

Hmmm, I wonder how much shuddering would occur if you opened a case to see a vesa local bus slot...still in use by a rather long video card?

Yes, I know...it belongs in a museum.

Seriously!!! I always try to convince the older folks that it's much cheaper to transfer your data to a post-1999 system than to continually try and repair problems with the old system.

I think I would shudder, and then cry a little inside.

EISA baby! thats high performance compaq right there.

PCIe x1 slots can do video, audio, networking, raid, simple IDE or SATA controller, Firewire, or USB, and any combination of those at the same time. As PCIe gets more popular we will see more cards, but right now there isn't much demand as everything is included built into the motherboard now anyways. Before PCIe 2.0, we were seeing the problem that if you have 2 video cards installed ALL other pci express slots were disabled and useless. with the additional lanes provided by the 2.0 specification we can have 2 video cards and an x-fi gamer card or whatever we really want.

PCIe x1 makes perfect sense for a wide variety of cards, it's just taking a long time to see these adapted. Lots of people have RAID cards for example, and PCIe is fast enough for a low-end RAID 5 array whereas PCI is not. You'd might as well be saying PCI is worthless and we should all go back to ISA.
