Do Socket FM2 CPUs require a non-APU FM2 motherboard?

Hello,

I just completed a new build with:

- This CPU:http://www.newegg.com/Product/Product.aspx?Item=N82E16819113329
- And this motherboard: http://www.newegg.com/Product/Product.aspx?Item=N82E16813130709

When I turn it on I get no beeps, no screen. The computer doesn't even toggle the monitor on with a black screen. The monitor cannot detect a video signal at all.

VGA cable is plugged in to the standalone GPU I have installed in my PCIe slot.

So, I'm wondering if FM2 CPUs (not APUs) require a non-APU-specific motherboard.

I have searched and Googled and cannot find an answer to this question, nor can I find a solution to my no beep, no screen problem.

This is not my first build but it is my first built using an FM2 chip.

Thanks for your help.

I found the problem.

The CPU was improperly seated in the socket. 3 pins were bent and not in the socket correctly. Thankfully, I was able to bend the pins back (gently!) and now the computer is working correctly.

I can't believe I did that... and now I'm worried about the stability of the chip. What do you guys think? It's running fine now. Do you think those bent pins will create instability? Maybe just wait and see?

Ugh, it hurts me just thinking about it... bent CPU pins... eesh. :(

Reset the BIOS to defaults.
Did you mount the motherboard on either raised bumps in the case OR standoffs, but not both, and have a standoff only where there is a mounting hole?
Is the 8-pin CPU power cable plugged in?
What graphics card do you have? If it needs one (or two), did you plug in its PCIe power cable(s)?

Thanks for the quick reply.

My GPU is a Sapphire Radeon HD 5450, passive cooling. It does not require a power plug from the PSU.

See here: http://www.newegg.com/Product/Product.aspx?Item=N82E16814102882

PSU is a Thermaltake Smart M750W (750 watt, 80 Plus Bronze Certified)

Is my mobo just a dud?

I believe the motherboard should be set up to auto detect if an integrated GPU is present or not. If not then it should default to the PCI-e slot.

The only thing I can think of that may be the likely answer is the motherboard is defective, or maybe the BIOS is too old to recognize the APU. But I think the chipset is newer than the CPU; I could be wrong. Are you positive the GPU works properly?

I would recommend you request an RMA and order a different motherboard like the following socket FM2+ mobo by Asrock. Socket FM2+ means that it is compatible with AMD's next generation Kaveri APUs / CPUs which requires socket FM2+. They are expected to be released on January 14th.

Of course you can simply return what you bought and wait for Kaveri to be released. I do not know what the performance difference between Trinity and Kaveri will be. However, Kaveri will have the new Steamroller architecture which to the disappoint of people with a socket AM3+ motherboard, AMD will not be releasing any next generation FX CPU in 2014.

Your motherboard is a dud. I would return ASAP (if you still can). The board will determine whether you have an APU or a CPU and determine whether or not to use the graphics card. If you get no beep and no BIOS then that means there is likely something wrong with the CMOS, in which case the board will not work and there is no way to fix it other than to get a new board.

Do you have a DVI to VGA converter? You usually get one with the graphics card. If so then try the DVI output on the graphics card.
Do the fans spin up when you switch the computer on?
Have you tried clearing the cmos?

I have the CMOS battery out now to reset the BIOS. Couldn't find a jumper to do it that way, so I'll just wait 15 minutes and put it back in.

The mobo is mounted on standoffs, and only where there is a standoff hole.

CPU power is plugged in.

The card didn't come with a DVI to VGA adapter.

The fans spin up, including the CPU fan and three case fans, and the power button also lights up when I turn the power on.

I wish this mobo had the LED error code display on it. I have that on my gaming rig and it is awesome!

Can you try the graphics card in your gaming rig?
If you have to RMA the board maybe consider an Asus or Gigabyte replacement.
I don't dislike Msi boards but have known 2 people who have received dead ones. Maybe they were just unlucky

You should be okay now it's seated in the socket and working:)

I think you are very lucky straightening the pins without breaking them.
I once snapped a pin off a CPU straightening it. I cut off a very small piece of wire the same length/thickness as the pin and put it in the hole in the motherboard where the snapped pin should have gone.
After about 30 minutes of playing and re seating the CPU it worked. I gave the motherboard and CPU away when i upgraded and it still works to this day. The CPU has not been removed from the motherboard since.

I'm glad it all worked out for you. To look on the bright side at least you leaned to be very careful next time you install a CPU into a motherboard.
A lesson i have already learned myself:D

If the pins didn't break, you should be fine.
I have successfully used the tip of a 0.5mm mechanical pencil to straighten AMD CPU pins, and I have also used a needle and a jeweler's loupe to straighten them, or to straighten LGA pads in an Intel socket.
In any case, all's well that ends well.

You might be right about that for me too! But hey, it WAS the correct answer (discovery of bent pins), and someone checking the forum because of a similar problem might be helped by discovering it, so it should be marked as such.

And I'll bet you thought us Moderators only wielded big nasty banhammers...

Noooo! I have found the moderators on this forum to be quite fair:)
I had an argument with one who was very rude and who i shall not name but that's it.
In fact anort3 gave me some very helpful advice in a lot of detail last week:D
