Hi all,

I bought a used AMD cpu for a cheap media server build. It is a AMD FX-670K, it is supposed to be a A10 APU made for HP (it was removed from a HP machine as per the seller). Anyways i installed it today onto a MSI A88X-g45 and i cannot get it to display video from the onboard VGA or DVI. It only works when i install a video card.

Any ideas?
How can i check if it indeed has a GPU on-board?

Here is a CPU-Z screen shot.(sorry for the quality cell phone pic)

I'm going to assume the 670K falls in line with similar A8/A10 APUs with their GPU disabled such as the AMD 750K.

However, there is no mention of this CPU on AMD's website or anywhere else except this:
http://valid.canardpc.com/i9n8z0

Therefore, it's very likely, if one follows the path of similarly named processors like the 750K, this one does not have a GPU on it or is disabled. It would explain why the onboard video does not work.

You could try running the Catalyst driver installation if it detects any GPU off the APU, or go into the BIOS and see if the option to allocate video RAM and/or disable the onboard GPU is greyed out or not.
 
I was checking the MSI website and they listed AD760KWOA44HL which points to a Athlon X4 Richland chip with no iGPU.

EDIT: Man I'm dyslexic. Didn't realize that the CPU-Z screenshots says 670K. Either way, I think it is a CPU without any GPU.

Then, you may have to check the BIOS of your board.

1.) If you see an un-greyed out option to allocate video memory and/or disable the onboard video, then the GPU should be working.

OR

2.) If it is greyed out and doesn't show up in Windows Device Manager, then one can assume your BIOS does not recognize the GPU entirely or something.
 
(Then again, it'd be odd if the BIOS only supported the CPU portion and not the GPU portion, but I'm going to chalk this up as a BIOS issue if that's the case.)
 
my guess is it's a specialty chip made for HP(OEM's) so that the gpu is only recognized by HP(OEM) bios. pretty common practice with HP hardware with rebranded GPU's in systems that only work on drivers modified/released by HP.

thats just my guess.

Greyed out cant change anything.

That could very well be the case.

http://www.msi.com/product/mb/A88XG45_GAMING_Assassins_Creed_Liberation_HD.html#support

According to that, there is no mention of an FX 670K under supported processor.

This could very well be a unique processor made just for HP's own PCs and only their BIOS can recognize both the CPU and GPU together.

I even checked the manual, there should be an option to use "IGD" (integrated graphics display), but it only sees the PCI-E graphics ("PEG") thus why it's greyed out.

I'm sorry that's the case with this processor.
 
This is the first unlocked-multi OEM chip I've ever seen... Strange how they call it an FX as well. Outside of the OEM board, it's pretty much a re-branded Athlon x4 760k.
 
Can't find squat about it within HP tech docs. Their part number for it is 751263-001, but there are no detailed specs to be found anywhere.

This CPU is found in some of the Pavilion 500 models, but even the spec sheet doesn't list the CPU details as far as the IGP goes. Being that the Pavilion 500 model with this processor also comes with a dedicated R7-240, I'd assumingly conclude that the FX-670K has no IGP.

The normal format for these parts has a 4 digit number... e.g. 7850k. Also, your description lists a Radeon HD 8670D. The "D" typically means discrete. Meaning it had an add-in card. The only reason to add a card that low end to a computer is if it didn't have an APU to begin with.

I'm going to go with this CPU being an OEM only part with a disabled iGPU or it never had one to begin with. Not sure why an OEM would go that route. Maybe they had a shit ton of low end CPU coolers that couldn't hand the extra heat of an APU or they had a shit ton of low end discrete video cards to offload.
 
Gotta love OEMs making everything complicated.

Based on the evidence and the naming scheme, I would think that this is a non-iGP APU. At least the CPU portion has been recognized correctly by your board. That is not always the case with OEM-unique parts.
