Hello there



I have bought this mobo MSI G41TM-P31 some time ago :
www.msi.com/product/mb/G41TM-P31.html

When I have bought, it I did not see that it had only pcie v1.0

Now I know there are some turnarounds to make it work with a 2.0 vga card , but google is not helping me find a way to do it

Right now I am still on the x4500 ( play WoW ) so it is ok , but in the future I will consider buying some powerful card that uses 2.x

I do not want to buy a new MB just to use that new card

Is there anything I can do to couple the MB with a 2.x VGA ?

More about : pcie

Well I cant edit my post so :

I know that in theory 2.x is backwards compatible

But I have heard rumors that some 8800s were not working inside 1.0 slots

So does anyone have had experience with a 2.x card inside a 1.0 slot ?

Pcie 2.1 card may have issues with 1.0. slot. But if you buy 2.0 card, you are quite safe.

I don't know about those rumors, but I had 8800gts320, 8800gts512 and 8800gtx and all of them worked fine on my MoBo's pcie 1.0 slot. I have now a gtx460 768mb working on the same slot.

^because they are all 2.0 card. I am not saying all 2.1 card will not work in 1.0, I am saying the only known compatibility issues are from 2.1 card. So, FunSurfer gives good indication of 2.0 card compatible with 1.0. Get 2.0 card.

8800's are 1.0 cards as far as im aware. G41 boards are newer and shouldn't have problems with 2.1 cards. 2.0 cards wil work in any board. Nforce boards like my 650i have issues with some newer cards. There is a BIOS update that fixes many issues, just make sure you have the newest BIOS. Also make sure your PSU is powerful enough for whichever card you buy.

:sol:  :sol:  :sol:  simply disable onboard graphics by selecting PCIE on bios settings as display device, and what about your PSU, and cooling I think your PSU is not supplying the required power, and that card is pretty hot.If u want to run a gpu u need at least 600 watt PSU. :sol:  :sol:  :sol:

iam2thecrowe , I have a 400 W PSU
for the moment I am thinking of a 5670 with a consumption of 70W

I know that I have to update the BIOS to latest
But on the manufacturer site
http://www.msi.com/product/mb/G41TM-P31.html#/?div=BIOS
at the BIOS download section there is not mention of PCIe 2.x support at all

Only talks about cpu /ddr updates

Also what is bothering me is that at this link :
http://www.msi.com/product/mb/G41TM-P31.html#/?div=BIOS
or by going at support -> VGA cards

you only see 4xxx as the latest supported VGA cards
