Title: Ga-M68MT-S2 (rev 3.1) PCI Express question
Post by: gc on December 30, 2011, 01:07:25 am

I don't really understand the difference so I will ask for your help.
The MOBO has 3 PCIEX slots. Are these slots
PCI Express
PCI Express 2.0 or
PCI Express 2.1
Does it matter. Will a PCIE 2.1 card work in a PCIE slot?

Thanks you in advance

PCI-E is 16 times on that board, That would be PCI-E 1 is before 2.0

The PCIE busses are backwards compatible so uyou shouldn't have any worry about them functioning. ;)

Thanks.
I guess from the answers and my reading on the subject that they would work but at a much slower rate that advertised. I think from this that there is no need to purchase a PCIE 2.0 when a PCIE 1.0 is available.

Similar Question.
I have a  m68mt-s2 based machine and am looking at upgrading from a cheap old Gainward 9500 GT Graphics card to a Radeon HD 6870.
The radeon is PCIE 2.1. Will the MOBO be compatable with the Graphics card understand there will probably be a performance loss due to less bandwidth.

Thanks
Giwan

Dark Mantis already answered you to this ,but there were cases in the past with Nvidia G92 8800 GT on VIA motherboards and ATI 5700 series cards that needed VGA BIOS updates to work on boards with lower PCI-E versions.

You will have to try it yourself.
I would advice you to update to a newer AMD chipset based motherboard though ,they are much better now than the Nvidia chipsets in many aspects.In this way you will get the maximum out of that excellent card.If you pair that video card with a Phenom 2 X4 975/980 you will be able to play any game out there at 1080 resolution.
