    Install PCIe 2.1 card on Dell 0RY007 Motherboard PCIe 1.0a

    I am using the Dell Inspiron 530 desktop PC, manufactured on late 2008. After week of purchasr I got a GeForce 9600 GT, plus it has been capable to perform just concerning whatever thing I wanted it as well. However I have a sentiment Battlefield 3 will be a different tale. I am looking for to upgrade XFX HD-687A-ZNFC Radeon HD 6870 1GB 256-bit DDR5 PCI Express 2.1 on this. It comes with a straight case/PSU for good cost, except I very soon found out my PCIe x16 slot is edition 1.0a. I have studied that PCIe 2.0 is backwards companionable through 1.0a, except that 2.1 might cause a few issues. Lots of recommended that updating BIOS may work out it. Do you think that it is possible?

    There are only some motherboards that give the chipset problem when they have a Via chipset or some of Nvidia, but this is not usual, even I have a 2.1 on an Nvidia chipset and does not give me problems. Anyway, if the video card and your motherboard is 2.0 to 1.0 or 1.1 is backwards even so smoothly, so you can’t use the video cards. So I tell you to fast, but look more issue if you want to see more differences.

    The difference is the width of the bus where all the information passes and 2.0 the bus is twice that of 1.0 but 2.1 is almost the same as 2.0. So comfortable that any PCI Express card is going to operate as either a different bus width.

    2.1 contain characteristic bumps of 2.0, in line with 3.0 - but it preserves the limits of bandwidth of 2.0. Fully forward and backward compatible, you can slip a card into a slot 2.1 2.0 2.0 or 2.1 card in a slot - but it will only get the functionality according to the specifications of the lowest version used.

    All ATI / AMD cards are backwards compatible. The PCI bus about 5-7%. Bottleneck will be even more than your CPU. So do not expect miracles in terms of performance. I was not aware of PCIe 2.1. But for information, the PCIe x8/x8 can run some CF properly (it seems) x16 you can do anything with that, then 2.0 or 2.1, in my opinion nothing important.
    The slots are also backward compatible, which means a x1 card, for example, are also inserted into a x4 slot, the extra three lanes will then simply not used. The opposite version (eg insertion of a RAID controller with 8 lanes in a PCI slot with 4 lanes) is not covered by the specification, but is supported by a lot of chips and cards. In particular, PCIe x16 graphics cards can often be operated PCIe x8 or PCIe x4 also

    There are already motherboards with PCI Express 2.1 standard, however, use both the G80 and the G92 chips currently matching or PCI Express 2.0 graphics card! But since I still only have PCI Express 1.1, it would still be interesting to see whether and how much to accept poor performance are. By the way, now the confirmation that PCI Express is backward compatible with 2.x.
