CrossFire Questions ..

[gfunk19]

Hey my friend has an Sapphire HD4850 512mb and he wants to crossfire it

He would like to know if he needs to purchase the exact same card to run crossfire?
for example: is it possible to run a HD4850 with a HD4830 and can u mix sapphire with asus?

Looking forward to the replies thank you xD

5. What happens when graphics cards with varying memory speeds and engine clocks are paired together?

A. In this scenario, overall performance will be adjusted to match the memory speeds and engine clocks of the lower clocked card. To obtain ideal performance, graphics cards should be paired correctly.

not to sure about the diffrent brands but it should work

that should help with which card work with what

Hybrid Corssfire says yes in theory.

It should work. The slower card will just bring the 4850 down to its speed.

Seeing that the prices are going to drop (all the 48xx cards) in the coming weeks, I would rather wait. You should be able to get the 4850 for the same price.

I want to test this over the weekend though, my bro is running a 4830, but think the buffer size might give problems. I'm running a 1GB and his is 512MB.

edit...

Mixing brands shouldn't matter either, for minimizing all possible issues though, it is advisable to run identical cards

NNNNNNNNNNNOOOOOOOOOOOOOOOOOO you CANNOT crossfire any card they MUST be the same and must be manufactured by the same company !!!!

Asus 4850 and gigabyte 4850 and sapphire 4850 all have different specs somewhere !

they should all be the same unless they are an oc version but even if it was diffrent the faster one will end up at the same speed as the slow one
