Hi,

Its been a week now of cracking my head and it seems i have no solution for this. My setup as below.

CPU: MSI fm2-a75ia-e53
Processor : AMD A10 - 6800K
Vcard: Sapphire Radeon HD 7750 Low Profile
Memory: G.Skill RipjawsX 2133MHz 8GB
Casing: Thermaltake SD101 PSU changed to 460watts

Am trying to xfire the APU and GPU but no avail. I tried a lot of tutorial on how to enable crossfire but my system wont auto detect. I have enabled dual graphics in BIOS forcing APU to IGD.

- GPU-Z shows Crossfire "Disabled"
- Hardware Display shows 8670D and 7700 displays
- CCC Hardware shows both cards are enabled

I have seen a video in youtube A10-6800K and 7750 LP xfire on a 300watts PSU.

Hope somebody can help me....

The integrated graphics adapter is automatically disabled when you install a PCI/PCI-E GPU.

Hence you only have one active GPU - so no CrossFire.

You need install a pair of identical PCI/PCI-E GPUs to enable CrossFire.

No It`s not the case as the first poster is saying.
To do crossfire with two Pci-e cards they have to match.

Model no: 7770 x 2 @ 2gb memory size.

The same is true for a Apu x Pci-e card solution.
They have to match in model no: and specs as in shade units.
8670D and 7700 won`t crossfire they simply do not match in specs.

Hi Philip, am trying to use the A10 IGD 8670D and the PCI-E 7750 graphics card to work with crossfire.

Hi Shaun,

Is there a specific driver that it will show 7750 instead of 7700?

managed to fix it by changing the board, i think its bios version issue as i had 2.2 version and the replaced board was on 2.1. After booting up and opened CCC then suddenly crossfire poped up.
