  • AGP4x/8x

    I know this issue has been beat to death pretty much, and that 8x is not much more than show and offers virtually no performance over 4x, but my motherboard is 4x and I am looking to buy a R9800 Pro. If i'm going to lay down $230, I want to get every bit of performance out of that investment I can (sans o/c) so can someone take a little bit of time and run a benchmark or two on 8x and then do the same tests for 4x and let me know the difference? I would really appreciate it, thanks a bunch.

    It's not worth wasting your money on a new motherboard for AGP 8x. The most difference that you'll see is 1-2%, which is not enough to warrant a purchase in my (and most peoples') opinion.

    Just stick to the current mobo - you'll be fine with it.

        so can anyone actually post a couple screenshots rather than just tell me that there's a 1-2% difference?

          What would be the point, it's common knowledge. Actually, 2% seems a bit optimistic.

              Someone tell me how to adjust mine down to 4x and I will do some benches.

              It is not supplied in my drivers.

                Can you control it via BIOS?

                  No, its an OS controlled feature (chipset driver enables 8x), no option in BIOS.

                  BTW whats up with all the MySQL errors?

                      so is mine, although it didn't take much digging at all to find it.

                        I've seen M-boards with Bios's that don't have an option to change the speed of an AGP port before, even though they support up to 8X AGP. If your board is like that and its not automatically dectecting the maximum speed of your AGP Port then I would try downloading the latest Bios for that board and updating it, you might have that option once the update is installed.

                              Trust me guys its not in my BIOS, I don't even need to look...you have no idea how many times ive been in and out of there in my overclocking/benching sessions.

                              Idiot-Savant, you need to get the Coolbits.reg file to open up the Clock Frequencies option in the drivers.
