[havoc08]

i have 2 hd3870x2 in crossfire mode well did have intill 20 mins ago now have only 1 card showing in devices and a solid red light on the offending card crossfire is now not a option in overdrive .i have reinstalled drivers and ccc.any ideas?

 

[havoc08]

cheers guys will try reseating it on its own and check psu cables

 

[havoc08]

none of the above worked ,anything eles before i give it the hammer test?

 

[havoc08]

the offending card is watercooled,and the other on air(waiting 2wks for ek waterblock out of stock}and the other card run with the cables the other card was on so even thoe the red light is on i dont think itspower even thoe the card isint getting slightly warm

 

[havoc08]

yep one card works on both sets of cables 8pin 6 pin the water cooled one that dosent work has no leak.someone said the red light on the card mean no power or lack off it but it don't work on its own or with different cables.

it had been working sweet for a month with water block on before this just put stock cooler back on and can see no damage and defo no leaks.how many time you think should hit with hammer:{

cheers hex i have to card s in crossfire so ive use the cables that work on the other card on this card and on its own,theres 3 lights on the x2 2 are together and 1 at the middle of the 8 pin the last one being the one thats on

 

[havoc08]

cheers hex it looks like the two together are the 6pin 8 pin and the 1 on its own which is on is the fault/error,card has been returned to ocks for test so will let everyone know the out come when i know cheers to all that replied.just hope this card dont die of a broken heart cos it s mate has died.

guys just been playing cod 4 ,amazing ,saying that the cards are 73c at max will be putting waterblocks back on sometime today. as for quad gpu *** can i say everything you throw at em they shine 3dmark06 says it all thats @4.2 ghz and stock on the cards.jambus did you have the same problems as me?

i more than happy with 2 x hd3870x2 set up and like you said hopefully improve with drivers,if you look at ** card the back plate acts as a heat sink for the mem and is hot to touch so if you where to put another card under it the top one would surly just be sucking in hot air as the gap between them is about 5 mm ,reason i have gone towards watercooling them.
