It does work, but sometimes, and this is mobo dependent, a 2.1 will be very buggy in a 1.0, to be safe we just suggest if you have a 1.0 slot you get a 2.0 card. If there is a 2.0 version of that card he might as well get that.

its not so much the card as it it the mobo. if the mobo has a BIOS that supports 2.1 cards you will be fine, if it does not (mostly in mass produced PCs like HP, DELL, Acer, etc.,) then you may have issues.

Regardless of whether it's 2.0 or 2.1, it's still motherboard dependent. Check when the last BIOS release for that card was created. If it wasn't within the last 2 years, I have my doubts. Not because a 2-year old BIOS won't support PCI-E 2.0 (it should), but because it definitely won't support 2.1 - it's too new a standard.

Originally, all ATI 5000-series were PCI-E 2.1. If companies are now making 2.0 versions and they can guarantee compatibility with a 1.0 or 1.0a motherboard, then get a 2.0.

did some more homework, after i ordered it due to RazberyBandit post

your right raz, their all 2. 1,in the HD 5000 series cards
the card makers all Lie and say 2.0 For marketing!
as not to "confuse" people
and under
system requirements for my card even says
PCI Express® based PC is required with one X16 lane graphics slot available on the motherboard.


they lie, knowing Some hit or miss older mb's 1.0s wont work!
the bastards, so now when it gets here, its a hit or miss, my mb as linked, is very old, but sure being sold, i don't see any 2.1 pci-e bios updates in the logs, but have updated the bios to its current date of 2010-06-29
so i have some hope if not tiny

i guest am just in a state of panic, its already been ordered,
i hope amazon takes gpu returns or exchanges for a other gpu if this does not work

it turns out all the cards are 2.1 , and they lie, knowing older 1.0s wont work

if thats true then it means im also running a 2.1 card on a 1.0 pcie slot. im using a hd5570 on a dell inspiron 530s.

Man I wish this issue had a clear answer, such as PCI-E 2.1 cards don't work or do work in PCI-E 1.0/1.0a motherboards, but it's not a yes or no issue at all. The truth is, sometimes they work, sometimes they don't.

It boils down to whether or not the BIOS can recognize and initialize the card, and that all depends on the specific motherboard and BIOS version in question. Specifically, the BIOS must have been programmed to support devices using the PCI-E 2.1 standard.

The problem arises because many boards using 1.0/1.0a PCI-E slots lost manufacturer support prior to the development (or acceptance) of the PCI-E 2.1 standard, clearly making them incapable of supporting devices using that standard. Not all 1.0/1.0a boards lost their support prior to the creation of the 2.1 standard, though. However, only boards which received continued manufacturer support that specifically included BIOS updates enabling PCI-E 2.1 support can identify and initialize 2.1 cards.
