Pci E 2.0

edk128 · 06-24-2008, 05:09 PM

I noticed Nvidia's newer graphics cards use PCI E 2.0.
I am not sure whether my computer has them.
I try reading what it has but I don't really undertsand it.
What slots does it have?

PCI Express 2.0

PCI-SIG announced the availability of the PCI Express Base 2.0 specification on 15 January 2007.[4] PCIe 2.0 doubles the bus standard's bandwidth from 2.5 Gbit/s to 5 Gbit/s, meaning a x32 connector can transfer data at up to 16 GB/s in each direction.

PCIe 2.0 is not completely backward compatible with PCIe v1.x. Graphic cards and motherboards designed for v2.0 will be able to work with v1.1 and vice versa, however v2.0 cards will not work in v1.0 and v1.0a motherboards.

The PCI-SIG also said PCIe 2.0 also features improvements to the point-to-point data transfer protocol and its software architecture.[5]

In June 2007 Intel released the specification of the P35 chipset which does not support PCIe 2.0 only PCIe 1.1.[6] Some people may be confused by the P35 block diagram[7] which states the Intel P35 has a PCIe x16 graphics link (8 GB/s) and 6 PCIe x1 links (500 MB/s each), for simple verification one can view the P965 block diagram which shows the same number of lanes and bandwidth but was released before PCIe 2.0 was finalized. Intel's first PCIe 2.0 capable chipset is the X38 and boards are already shipping from various vendors (Abit, Asus, Gigabyte) as of October 21, 2007.[8] AMD starts supporting PCIe 2.0 from its RD700 chipset series. NVIDIA has revealed that the MCP72 will be their first PCIe 2.0 equipped chipset.[9]

[edit]
PCI Express 3.0

In August 2007 PCI-SIG announced that PCI Express 3.0 will carry a bit rate of 8 gigatransfers per second. The spec will be backwards-compatible with existing PCIe
ati has something built into their cards to overcome any problems

Thanks, I get that but I don't get how many PCI E 2.0, PCI E and PCI slot I have. I was planning on getting either dual graphics card or a high end one but I am not sure of my slots.

i have never used a nividia based m/b so don't know for sure if they are pcie2 capable

PCI express 2.0 is backwards compatible with v1.1 and 1.0.

From wiki:

PCI-SIG announced the availability of the PCI Express Base 2.0 specification on 15 January 2007.[8] PCIe 2.0 doubles the bus standard's bandwidth from 0.25 Gbyte/s to 0.5 Gbyte/s, meaning a x32 connector can transfer data at up to 16 Gbyte/s in each direction.

PCIe 2.0 is backward and forward compatible with PCIe v1.x. Graphic cards and motherboards designed for v2.0 will be able to work with v1.1 and v1.0, and vice versa. In some rare cases it is possible that a PCI-E 2.0 card will not work correctly on a PCI-E 1.0a slot. This is only limited to certain video cards.

So far all Nvidia Geforce Graphics cards that use PCI-E 2.0 are backwards compatible with "Nvidia" Chipset motherboards that have PCI-E 1.0, 1.0a and 1.1. But try not to use a motherboards early 2005 as it may not work.
I myself am running a 9800GX2 in a PCI 1.0 slot and i have the same results as a PCI-E 2.0 slot.
