PCIE V1 and PCIE V2

post #1 of 8
Thread Starter 
Hey guys

Ive recently been upgrading a PC for a friend.

I got him a 750watt PSU and a 6770 for his current PC. He has a ECS HT2000 motherboard which is only PCIE x16 v1.1 but the GPU is PCIE x16 v2.x.

When I try and boot the PC nothing happens no beeps no nothing :/ but with the old GPU a 7300LE it works fine.

Could the v1 and v2 be the issue? I have read online that it should be backwards/forwards compatible.

That could be the problem, some video cards have backwards compatibility, but some don't. Its kind of one of those "optional" things that some companies put on their products to make em sell.

The other possibility is that you have a bad 6770.

PCI -e 2.0 is completely backwards compatible with 1.0.

Could be a bad card or PSu or other connections (you do have the pci-e power cable plugged into the card, right).

Are you sure about that? When I did research, it seemed to me that it was kind of iffy. As in: it depended on your board and card to both be fully compatible. However, that was a long time ago, so I dont know if my information was from "legit" sources, if you know what I mean. smile.gif

The only PCIe compability issues that I have ever heard about was with VIA's chipset implementation. However, who runs VIA chipsets?


Would you happen to have a POST code reader?

Haha, thanks. I guess I was reading from "shifty" sources all that time ago. You learn something new every day, I guess! thumb.gif

Right ive checked the mother board site and it says it is only V1 compatible. I have swapped the psu alread and it works fine. Also tested the card in my sig rig and that worked fine so its not the card or the psu. Also yes I have plugged the power cables in lol what do you take me for?
