What version of PCIE slot my motherboard BIOSTAR P4M900-M7 SE has?

Solution


That will work perfectly fine, left 4 dead and GTA IV will work on that as well. Get a 2gb variant if you can preferably.

Your board:

http://www.biostar.com.tw/app/en/mb/introduction.php?S_ID=289#spec

Unfortunately there is no listing as to 1.0, 1.1, or 2.0, it may be 2.0 based on the age of the chipset, but VIA's website doesn't list it in the details. PCIe 2.0 came out after this chipset did, but that doesn't mean support couldn't be added. That said it really does not matter, even PCIe 3.0 cards will work in a 1.0 slot.

If you check the link I posted you can download the manual and it also lists it as PCIe 1.0a on page 12

The link you posted didn't mentioned if its 2.0 or 1.0 and the guy above said its 1.0 and the link is user manual for FE not SE
I searched for SE manual and i found it in PDF format downloaded it and it were mentioning SE & TE without also mentioning if its 1.0 or 2.0

Click the link I posted

http://www.biostar.com.tw/app/en/mb/introduction.php?S_ID=289#spec

This is for the SE motherboard, click on Download, and download the manual. Go to page 12, it lists right at the top PCIe 1.0a

Direct link to the manual:

http://www.biostar.com.tw/upload/Manual/P4M90-M7A_P4M89-M7B_070611_B.zip

Text direct from the manual:

PCI-EX16: PCI-Express x16 Slot
- PCI-Express 1.0a compliant.
- Maximum theoretical realized bandwidth of 4GB/s simultaneously per direction, for an aggregate of 8GB/s totally.
PCI-EX1_1: PCI-Express x1 Slot
- PCI-Express 1.0a compliant.
- Data transfer bandwidth up to 250MB/s per direction; 500MB/s in total.
- PCI-Express supports a raw bit-rate of 2.5Gb/s on the data pins.
- 2X bandwidth over the traditional PCI architecture.

Upgrade your motherboard then, they're dirt cheap now a days and are often neglected when experienced people are upgrading. Since your motherboard does not support 3.0, I'm guessing it is rather old along with other hardware components. Maybe even look into purchasing a completely new system.

Honorable
what gpu are you trying to buy? Every pci-e 2.0 or 3.0 is backward compatible on your 1.0 motherboard.
If you looking at high end gpu, u might have to change your whole system as ur performance will be halted by cpu and to some extent by your motherboard's pci-e slot.

Both GPUs are backwards compatible, they should work on any PCIe version.

Not true, As I mentioned in my original post the version of PCIe of your board does not matter, PCIe 3.0 will work in 2.0 or 1.0 slot no problem.

Even if you got the fastest LGA 775 processor that will work on your board, it will still bottleneck any card as fast as an R9 270x or GTX 750/950. Just keep that in mind within your expectations.


EDIT: Just saw what you plan on buying. Sorry I missed that post. Those will work fine together and with your board.
