CrossFire Question - MSI B85-G43 Gaming Motherboard

I have a CrossFire question regarding MSI' Mid-Range gaming Motherboards and more specifically the B85-G43 Gaming MOBO.

My RIG
CPU: Intel Core i5 4670k
Motherboard: B85-G43 Gaming MOBO
Current GPU: MSI Radeon r7 250 OC
Future GPU's: MSI Radeon r9 270x Gaming (x2 in CrossFire)

Okay so the MSI Gaming motherboards are heavily advertised as CrossFire Ready.

The B85-G43 Gaming MOBO has the following for multiple GPU CrossFire setup
PCI-E 3.0 x16
PCI-E 2.0 x4

So I am guessing from these specifications and being advertised as CrossFire ready, the PCI-E transfer rate for Dual CrossFire setup will be x8 x8?

Can anyone please confirm before I waste my money on 2 GPU's

Thanks :)

  1. Best answer
    No. That motherboard technically supports Crossfire, but the second card will only run at PCIe2.0x4. Generally you want one that's advertised as being SLI-ready, because the conditions are more stringent.

    I'd suggest getting a Z87 or Z97 board - you'd also be able to OC the CPU, which you can't on B85 really.
  2. Basically long answer short. My only real feasible and recommended option would be to buy a more powerful single GPU.

    I hate you MSI!

    Anyone had any success running CrossFire with x16 and x4
  3. Or a new board.

    It works, but is slow.

    PS: That's not MSI-specific. AFAIK, no one makes B85 boards that can do x8/x8 CF/SLI.
  4. I understand its not MSI Specific. They are just pro at marketing, less pro at Customer Service.

    Thanks a lot for the help tho :)
