Is it possible for me to Crossfire these two Graphic card( r9 270 and r9 270x)

[Milleus]

Hi Community,

i have recently bought a 2nd graphics card so i could try out crossfire, but after playing arround with it, and reading other posts here on the forums i am now unsure if my cards can be crossfired.

here are my two cards:
my old card: ASUS R9 270X DirectCU II TOP
http://www.techpowerup.com/gpudb/b2450/asus-r9-270x-directcu-ii-top.html

and

my new card: GIGABYTE R9 270 WindForce 2X OC
http://www.techpowerup.com/gpudb/b2623/gigabyte-r9-270-windforce-2x-oc.html

both cards are installed correctly and in games i can choose one or the other, but in the CCC, under performance i do not have the crossfire option, only amd overdrive and frame rate

i have read many posts in here, about uninstalling all drivers, taking out cards one by one, and reinstalling, using different versions etc.

i thought i was carefull enough, by choosing two cards that were both 270's but then afterwards i realise that one is 270x and other 270.. So main question is:

Do they even work together for crossfire?

No they don't
http://support.amd.com/en-us/kb-articles/Pages/Crossfire-Chart.aspx?hootPostID=7806dc9eccc491f9d779e1bc1cfd10f6 I'm sure you've heard this alot, but you should have gotten a better single card anyway. I know you just wanted to try it out but...

YES, you can crossfire them. 270 and 270x are identical; 270x has higher gpu clock only, which AMD drivers will automatically synchronize with 270 gpu clock

you have to connect the Crossfire bridge as well

so one says: "they don't" and one says "they can".
what i read was that as long as 270x or 270 has the same "speccs" like both 2k ram and not one with 4k and 2k, i should be able too.

@azca: i ahve put the bridge on, but i will now reboot and double check, thanks for the fast respond really amazing!

 

[ESPclipse]

AMD's CrossfireX compatibility is not as strict as Nvidia's SLI, and so bridging cards of the same family is possible. I believe that those cards will support crossfire with one another, at least assuming the content of this thread is true. That being said, you are better off with a single superior card in just about any circumstance.

so i just opened my computer and checked if the bridge was attached propper, and it is.
i identified the two cards i am using with "TechPowerUp GPU-Z" and looking at the box of my new card.

but it is still not working..
when entering a game like path of exile it shows both graphics card i can choose from.
and still in catalyst control center, it does not show the option for crossfire in the performance tab


anyways, i didnt have that much money this month, so i wanted a cheap solution.. i guess since i packed it out, i can't return it.

DOES your motherboard support crossfire? what are your computer specs...?

 

[Milleus]

@azca: again thank you for the fast respons. Here is a picture of my computer speccs:

i am sorry but my knowledge about motherboard supporting CF is limited...

 

[azca]

^your motherboard DOES NOT support Crossfire or SLI unfortunately. If you want to do crossfire, you'll need a motherboard that supports it.

 

[Milleus]

okay, step 2 is now advice seeking, and thank you SO much for your help.

what should i do? buy new motherboard? if so which?
try and sell my graphics cards and buy a new one, if so which one?

i am not a rich person, but i guess i could spend my entire august earning alittle extra.

 

[azca]

you have 2 options
1) buy a new motherboard
2) buy a new video card

I sent you a PM.

Thank you.
