4870 + x600 PCI-e x1 on P45?

[MN12BIRD]

Okay I have a 4870 and an x600 PCI-e x1 card. I can use one or the other but when they are both installed it runs off the x600 and the 4870 shows up as being disabled. I'm running a P45 motherboard that is NOT crossfire. Should this be possible? I want to run the 4870 as the primary card and the x600 as a secondary card for more monitors and the fact it has s-video/composite output while my 4870 does not.

Thanks

Well I updated my BIOS and the ATi drivers to the latest and now instead of showing this...

Primary: x600, Secondary disabled: 4800 series

It only shows the x600. Before in device manager it showed both cards as working now it says windows has disabled the 4870.

No one has done this? People running two cards for 4 monitors on non CF boards?

You most likely need to run two separate video drivers, one for the legacy card and one for the 4870. Unfortunately you cannot use two different drivers in Windows.

Hm. Maybe you need to use an older version of the driver that supports the X600 and the 4870, if they exist.

This may or may not help you: Due to some circumstances, I had to use an X1300 in my primary PCI-E 16x slot and a 4830 in my secondary slot. I was using a fairly recent ATI driver. (9.7 or 9.8) Well it turns out that they (I THINK) cut support for the X1300 in whatever driver I used. The BIOS screens and XP Boot would show up on the X1300, but as soon as XP had booted (between the black screen and the logon screen) the display shifted to the 4830. After I log in, I get the 'Found New Hardware' thing for the X1300. So either you need drivers for both cards, or a single driver that works with both cards. (But as erocker said, having different drivers for each card doesn't work in Windows)

I've done it before, sort of.
Ran a pcie card at x16, and an agp card at the same time, driving a total of 3 monitors, both ati.

I've heard it's not possible to do in vista, but completely possibly in xp and 7.

if the ati package only installs drivers for one card, try installing it for one card, then taking that card out and installing it for the other card as well with the "driver only" package.
