Is it possible to use HD4850 and HD5850 together?

[pspcpog]

I've got HD5850 in my main system and there's
a HD4850 lying around. Is it possible to use these
two cards together somehow? No CF, no Eyefinity,
just each gpu running different monitors.

i think they both need to be either HD48** or HD58** not mixed, but am probably wrong.

Your 5850 should be able to output up to 3 monitors...do you need to output to more than that?

You cant crossfire those two.

Need to be in he same family. I.e 58xx series.

Even if you could it wouldnt be desirable as xfired cards run at the speed of the slowest card.

So xfire 4850 and a 5850 if it were possible would run like a 4850x2

There should be no reason why you can't use the two cards to output to multiple monitors, so long as you know that you'll only be able to game on the primary monitor on the primary card, with no CrossFire or EyeFinity.

Thanks for the inputs but as I've mentioned in
my question, NO CF and NO EYEFINITY, but just
each gpu powering a separate monitor,
so that each card's performance is fully utilised?

Cheers for that, I'll see how this setup goes.

i suppose, thinking about it it should work, i can run my 2xHD6850s in CF with my OBV so if it can do that then i suppose it would do it with 2 cards. but i think as soon as i plug something into the OBV the monitor connected to the 2xHD6850 cards revert to HD3000 speeds. i think, been a while since i tried it.

how do you propose to fully utilize the performance of both gpu's? to do that you'd need a game running on each, with two complete sets of inputs (ie, keyboard and mouse) independently controlling each. In short, dont bother.

if you need more than 3 monitors, sure. but a windows desktop isnt going to tax any gpu. otherwise just use the 5850 surely?

 

[pspcpog]

I thought of it like optimus tech when it comes to dealing with an external monitor, which assigns gpu A to monitor A and gpu B to monitor B. This way, provided that you have enough cpu power, you may fully utilise the performance of both gpus with only one set of inputs controlling both screen at the same time. Any thoughts?

For a secondary monitor for desktop use only you could stick a ViRGE S3 in there and it would be suitable.
