It will work. You could see an improvement over a standard 4870.
4870 + 4830 xfire

it's just the same as xfiring two 4830s. but it's still an improvement over a single 4870

thats what i was thinking cuz the 4870 will only run as fast as the 30...
dont hold me to it but i think there are few ppl that are xfiring two 4830s and are great performance

but enough of one to warrant keeping the card

but since with my mods the 4830 outperforms a stock 4850 it will be like xfired 4850s??

yep. the logic for xfiring is, the higher specs tune down with the lower specs, and it's the lower ones that gets doubled.

so having a voltmodded 4870 will be useless as its just lowering itself to the 4830

That's the idea... your 4870 tunes itself down to run in sync with your 4830. That said, you'll be wanting to focus on your 4830 overvolt/cooling/overclock as it'll be the limiting factor

Sorry guys, not true.
The only thing that will scale down is memory size, only if you are mixing cards with different amounts.
CF is different than SLI in that no card slows down, they just render their frame at their respective speeds.
You can run each card at whatever speed they can reach.
I CF'd a 4870/50 together results were not bad at all, results here.
Oh yeah
I'd sell the card, put the $ toward another 4870.

Sorry, but your 4830 is not as a fast as a 4850. It only has 640 SPs compared to 800. It would take a massive clock speed increase to overcome that... One that you won't attain without heavy volt modding and possibly, LN2/DICE.

well, i couldn't find a test there that has mixed crossfire.
i'm sure with xfired 4870s, it's possible to have different clock speeds and without the other getting to tune down.
but xfiring a 4870 and 4850 together is a different story. the main thing is the 4870 will tune down to ddr3 w/c is its advantage over the 4850(not to mention sp, and memory size in different models). so in the end, it's just like 2 4850s in xfire.
here's a sample

excuse you but mine is heavily voltmodded and it does exceed a stock 4850 go through the thread in my sig the proofs in there
