I recently recieved my second HD3870, I tried to set up crossfire, the
driver installed fine, on reboot, when I go to device manager, it has a
warning against the first card, code 43. This is a software problem. I run
vista home premium 64 bit, a Q6600 @ 3.0Ghz, 8Gb ram, auzentech prelude
soundcard, terratec tv card, 4xx WD 500GB sata2 drives, all this is on an
asus maximus formuls motherboard. All software/ drivers are up to date. I am
thinking that the cause of this problem is simply poor drivers from ATi, and
I'd appreciate a few opinions before I begin to start trying to assign IRQ's
at the bios level. TIA

Is your 1870 Crossfire of CrossfireX? CrossfireX will not run on a Crossfire
MB.

Ignore JamesH's comment (CrossfireX has no relevance here since you are
dealing with only two cards).

When upgrading to a Crossfire setup, ATi recommends uninstalling the driver
for the existing card, then reinstalling driver for both cards at the same
time.

If that doesn't work, try the fix suggested here. Works for some people:
http://www.neowin.net/forum/index.ph...st&p=587866108

Remember that Crossfire doesn't come enabled by default. Until you click on
the "enable Crossfire" checkbox in Catalyst Control Center, Windows treats
this as a simple multi-card setup (commonly used to drive 3-4 monitors,
etc.). A multi-card setup is a fairly basic driver functionality; it's not
too likely for ATi to screw up that bad.

Aside from the little icon in Device Manager, can you continue loading
Windows and opening applications, or does the Code 43 error message stop you
from using the comp?

All 3870s are crossfire X. That only means it will work with more than
2 GPUs, if the motherboard supports it. It doesn't mean it won't work
with a crossfire motherboard, it IS crossfire.

When upgrading to a Crossfire setup, ATi recommends uninstalling the driver
for the existing card, then reinstalling driver for both cards at the same
time.

That's what I did.

I have no checkbox in the CCC to enable crossfire!

The PC boots, and everything runs. When I check in device manager, I have an
exclamation mark against the first 3870 in the list, properties reveal the
code 43 error. Also, I only have one Crossfire connector between the two
cards, which I have plugged into the left connectors, nearest the DVI
output, as I only got one supplied. I assume that it only needs one? I'll
try the fix suggested and see what happens. Thanks so far, First!

Well, tried that fix, it didn't work. Maybe I will try earlier versions of
the driver. I have cat 7.12 in, perhaps I will try 7.11.

Crossfire X only works on the new AMD motherboard. I see nowhere that the
two versions on interchangeable. So far every one seems to be having
problems trying to run CrossfireX on a Crossfire MB.

You need both Crossfire ribbon cables. Each 3870 card should be supplied
with one ribbon cable in the box. So if you got two cards, you would have
two ribbon cables.

See picture:

Once the code 43 error goes away, remember to check the "enable Crossfire"
box in CCC.

Crossfire X supports more than 2 GPUs on compatible motherboards, that's
correct. Crossfire X cards also will work with 2 GPUs on a Crossfire
board. The 'X' is added functionality, not a completely different
specification. BTW, he's only using one connector. That might be the
problem, you think?

I only received one connector! Cheers for the help!
