PCI-e version 2 card, does it work in a pci-e v1.1 board?

[JonJ678]

I ran into the insta-lock thread http://forums.overclockers.co.uk/showthread.php?t=18103502 which I'm not trying to revive.

I thought pci-e 2.0 cards worked just fine (maybe fractionally slower?) in older boards. It seems the angry owner of the 5770 (which I assume is pci-e 2.0) disagrees with this.

I'm fairly sure the angry poster is ill informed, but he's sufficiently confident that I'm doubting myself. Could anyone confirm?

I think it should be fine, sounds like the poster did something wrong on the install perhaps or has another faulty component as it sounds like it was RMA'd back to OcUK and was working fine, hence they charged the rather mean 'testing fee'.

I thought they were all backwards compatible to be honest. There is just a bandwidth limitation that may or may not be met depending on the performance of the card.

yes i think it should work, but what i read from that thread is that he seems to think the card is 1.1

Yea, I read this thread and did a double-take as I was sure PCI-E 2.0 is backward compatible to 1.1.

I checked the interwebs, and it seems that we are right.

Wiki seemed to back me, but that's never terribly reliable. Looks like the chap's going to have fun at small claims.

Cheers guys

It'll work fine bar a minor performance hit

Works ok in my rig.

Is definately backwards compatible with 1.1

 

[cmndr_andi]

Its kind of funny really. If the guy didn't title his tread "refund" and complain a lot we probably could have got his system working.

Hopefully he sees this thread and we can sort him out.

If he hadn't of sent it back to OcUK saying it was faulty he could have saved himself £20 too. I think it's too late now anyway, OcUK will probably return it to him, and hopefully he's seen this thread. I was about to post in there and ask how he knew it was faulty, perhaps he can clear that up for us?
