Noob with crossfire.

[emii89]

Hello! I have a question. A few weeks ago, I bought 2 Sapphire 5850 used with Accelero TwinTurbo Pro's installed ... but not if crossfire is working. While the plate is connected to the monitor (top), temperature rises and works ... the one below, does not raise temperature values ​​in the catalyst are half strangers. Here I have some photos to help me and if they can tell if something is wrong.

emii89, for crossifre you only need 1 bridge.

To enable Crossfire you have to go into the AMD Vision Control Centre > Performance > AMD Crossfire x

OMG! sorry... i did the translation, but i didnt used it .

Edited post #1.

Thank you.

I did it! and the crossfire its "enabled", but im not sure if its working. BTW, now i cant put it on. So... I disconnected everything and now I'm cleaning up a little. I will try to restart and enable it ... and that by checking "enable crossfire", it was returning to the option "disable"

Look the 2 new images...
Im pretty sure, that the secondary 5850 its not working... i mean... it doesnt hot... themps are always at 30º... the top 5850 when its working is at 50/55ºc

try running 3dmark 11 or some other gfx intensive benchmark. Disable crossfire first and check results with a second run with crossfire enabled. Also the second card usually remains idle until its needed, ie any desktop app. My 2nd 4850 hardly broke a sweat unless i was playing BF3 or something intensive.

If Cfire is enabled your gpu-z will look like mine.

 

[emii89]

good idea... i'll try a 3dmark benchmark and i'll show it in this trhead!

Why use two bridges for a dual gpu/crossfire setup? You don't need to use two bridges for such setup, otherwise it will harm performance. Try to use 1 bridge instead and see if it works better.

 

[emii89]

i dont know , it comes with the 2 bridges, and i connected it xD. Now is with 1 bridge.

I did the 3dmark 11 benchmark...
Wth CF desactivated, the result is x1294, and with CF activated, its x2506. So, apparently its working...

Thanks all for your help!!

EDIT:

And thats are my specs:

Phenom II x6 1090t BE.
Hyper 212+
2x2gb G-Skill CL9 1600 mhz

No problem, and don't forget about the Thanks button to the bottom right of each post

False. There is absolutely nothing harmful whatsoever about using 2 crossfire bridges.

Though it is true that only one is actually necessary.
