GA-G41M-ES2L >>> Does it have a PCIe 2.0 slot or 1.1?

GA-G41M-ES2L >>> Does it have a PCIe 2.0 slot or 1.1?
« on: December 02, 2009, 04:05:01 am »
I just got a GA-G41M-ES2L motherboard and I'm seeing that the G41 chipset is PCIe 1.1 not 2.0 but newegg and the Gigabyte site say it's 2.0

Anyone know anything about this?
Thanks,
Peter

Where abouts on the gigabyte site does it say its 2.0?  ??? But if the site says it does then it will. Although both 2.0 + 1.1 will work with any pci express graphics card and theres no difference in performance between 1.1 and 2.0 (at the moment)

I would imagine it would be PCIe 2.0 then. I'm pretty sure G41 can support 2.0. Though like I said, theres very little performance gain of 2.0 over 1.1. Even with a top end graphics card :)

I found this about PCIe slots...

PCI Express 2.0

PCI-SIG announced the availability of the PCI Express Base 2.0 specification on 15 January 2007. 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 backward compatible with PCIe v1.x. PCIe 2.0 cards have good backward compatibility, new PCIe 2.0 graphics cards are compatible with PCIe 1.1 motherboards, meaning that they will run on them 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.

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

In June 2007 Intel released the specification of the Intel P35 chipset which does not support PCIe 2.0 only PCIe 1.1. Some people may be confused by the P35 block diagram 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 was the X38 and boards began to ship from various vendors (Abit, Asus, Gigabyte) as of October 21, 2007. AMD started supporting PCIe 2.0 with its RD700 chipset series and nVidia started with the MCP72. The specification of the Intel P45 chipset includes PCIe 2.0.

So am I understanding this right that this motherboard uses graphics card that run at 2.0 at 1.1?

Yes they're backwards compatable. Which is why it doesn't really matter if your board is 1.1 or 2.0  :)

So will this board run at 500 MB/s or would I need to get the board with the G45 chipset?
