crossfire help please

[Unionjack]

Hi all - just a quick question when crossfiring do i need 2 of the adaptors/cables from one card to another or is it just 1 ?

im only asking because the latest xfx 5770 card i have just received has one slot the same as my older card but the second is a lot longer and will not fit the adaptor/cable ? ( wider plug is on the right of the card )

so basically my 2 cards are like this

---- ----
---- ---------- <------- this is the new card

i hope you can understand what im trying to say .

manythanks

You only need one bridge for crossfire. I've heard it's debated whether 2 improves performance but only 1 is necessary

ok thanks for that - but how do you explain that on the newer card one bridge is a lot wider than my original one ( both are the same card ) and bought within only a few weeks of each other ?


----------- ------------- old card

----------- ------------------------ new card

i just cant understand why they would be different ?

thanks again

That seems very strange. Are they 'Exactly' the same? Is it one of those things where you have a slightly different model with a different shaped cooler-case etc? Sounds to me like a different model of the same card...
Not really anything to worry about unless you're looking at tripple or quad configurations in the future.

no exactly the same model ( checked that on the box from OC ) - as i said the older of the two was purchased only 4 weeks ago & they are a match apart from the diff size bridges / also noticed on the monitor sockets , the older ones are black on the newest card they are red ? dunno if that means anything
