Pcie and Pci express 2.0 question

[Paintedeyes87]

This might be a really stupid question. I'm looking for a new motherboard 1366 that has both pci express 2.0 and pcie. I'm a gamer and sound engineer. I currently have this

And i might be interested in getting another one and maybe a pcie usb3 card. so my question is this, is it even possible to attach one of those cards into the larger pci express 2.0. I know they're different sizes, but who knows!

i dont understand, PCIe 1.x and PCIe 2.0 are phsically the same size.

This is a PCIe card

and this is a PCI express 2.0 card.

different.

PCI Express (standard)
A PCIe card will fit into a slot of its physical size or larger, but may not fit into a smaller PCIe slot. Some slots use open-ended sockets to permit physically longer cards and will negotiate the best available electrical connection. The number of lanes actually connected to a slot may also be less than the number supported by the physical slot size. An example is a x8 slot that actually only runs at ×1; these slots will allow any ×1, ×2, ×4 or ×8 card to be used, though only running at ×1 speed. This type of socket is described as a ×8 (×1 mode) slot, meaning it physically accepts up to ×8 cards but only runs at ×1 speed. The advantage gained is that a larger range of PCIe cards can still be used without requiring the motherboard hardware to support the full transfer rate, which keeps design and implementation costs down.

PCI Express 2.0

PCI-SIG announced the availability of the PCI Express Base 2.0 specification on 15 January 2007.[9] The PCIe 2.0 standard doubles the per-lane throughput from the PCIe 1.0 standard's 250 MB/s to 500 MB/s. This means a 32-lane PCI connector (x32) can support throughput up to 16 GB/s aggregate. The PCIe 2.0 standard uses a base clock speed of 5.0 GHz, while the first version operates at 2.5 GHz.

PCIe 2.0 motherboard slots are fully backward compatible with PCIe v1.x cards. PCIe 2.0 cards are also generally backward compatible with PCIe 1.x motherboards, using the available bandwidth of PCI Express 1.1. Overall, graphic cards or motherboards designed for v 2.0 will be able to work with the other being v 1.1 or v 1.0.

And from the link you posted:

Fully PCIe 2.0 compliant x1 card that can be used in x1, x4, x8 and x16 slots

You shouldn't run into any problems 😉

 

[Rifter]

your first link is broken, the 2nd linked card is a PCIe 2.0 16x card, and it will fit in a PCIe 1.0 16x slot since they are the same size.

I think Paintedeyes87 was just re-posting the link the OP posted, which is a PCI-e 2.0 x1 card, and saying it is different to a PCI-e 2.0 x16 card. It is, but it will still work in a x16 slot, as it says in the manufacturer information:

# Cross-platform (Mac/PC), high-bandwidth PCIe (Express) card provides dedicated DSP for native DAW applications
# Card features a single Analog Devices SHARC 21369 floating-point processor that delivers 2.5 times the DSP power of the original UAD-1
# Fully PCIe 2.0 compliant x1 card that can be used in x1, x4, x8 and x16 slots

Peter is right.

There can be some incompatibilities with specific motherboards (where in the GFX slot, some other cards are not recognized properly or in older BIOSes, some cares are not recognized e.g. Asus Xonar HDAV Deluxe in an eVGA 680i SLI) but generally all PCI Express cards (1.X and 2.X) will work any PCI Express slot as long as they can physically fit (e.g. X1 in a X16 slot, but not the other way around (though it has been shown to work sometimes).

Therefore OP, since your card is X1, it will work in any PCI Express slot, short of any motherboard issues.

Assuming everyone invlolved(mobo maker, card maker) follow the PCIe specs any card(1x,4x,8x,16x) will work in a 16x slot.

For that matter larger cards(8x,16x) will usualy work in smaller slots(4x,1x) too if you cut the end off to make it physically fit in the slot, some mobo's even have open ended slots for this reason. You will however have less bandwidth obviously.
