GA-P67A-UD4-B3 Will Not Power Up

[Dark Mantis]

All it would indicate is that there is no pulses being transmitted to the buzzer. The reason for this would still be unknown. It would just help to hear a beep code as it would point us in the right direction. If you have a multi meter try checking the supply voltages of the PSU to the motherboard.

I removed all ram from the board and did get beeps which I think is a good sign.  Installed 1 stick of memory in DDR3 2 and got one beep and did get a post.  Installed the second stick of memory in DDR 3 4 and then no beeps and back to the same restart attempt every few seconds.  Installed the two ram modules in DDR 1 and DDR 2 and the system will start, but when I install per the manual to have dual channel enabled I run into the problem.  The memory I am using is Patriot G2 Series PC3-12800 1600 MHz, 2 4GB sticks.

[Dark Mantis]

THat is where your problem lies then. The memory should be installed in DDR3_1 and DDR3_3 It is Dual Channel!

[BillyE100]

That is how I had the memory installed initially, but this is when the system will not post.  Have tried modules in DDR1 and DDR 3 and moved to DDR 2 and DDR 4 and will not post in either case.  When I install just a single module the system will post and when I install both modules in DDR 1 and DDR 2 it will post but I do want to have these in Dual Channel so does this mean the modules are not a matched set?

[Dark Mantis]

Did you purchase them as a matched kit ?

[BillyE100]

Yes, purchased as a matched kit.

[Dark Mantis]

In that case i think we need to check them for faults. Please follow these insrtructions EXACTLY.


I would suggest that you download and run the latest version of  Memtest86+ to check your RAM first.

Memtest86+        http://www.memtest.org/

Insert one stick of memory in slot 1 and run Memtest on it for at least 10 complete loops/cycles and if there are no errors then swap it over with the next one and continue untill you have checked all  modules.
 
If you have any errors the module is faulty.

If you have any faulty modules you will have to return the whole kit as they are matched.

Post back when you have done that with the results.

The memory testing is complete and it indicated no problems with either of the sticks (2 x 4GB sticks).  So what does this mean?  Could it indicate that there is a problem with the DDR 3 and DDR4 slots on the board?

[Dark Mantis]

It is beginning to sound like that might be a possibility. However let's check the CPU socket for any bent pins first.


Take all the usual anti-static precautions.

Very carefully remove the heatsink and fan. Probably a slight twisting motion is best to release the two as the thermal paste can act like a glue.

Once off remove the CPU taking extreme care both physically and electrically(static) and place somewhere safe.

Make sure that the lighting is very good and even.

Now scrutinise the socket for any pins that are out of alignment, even slightly.
If in any doubt whatsoever take a couple of macro (close up) photos of the socket and post them on here for us to check.

Also look at the bottom of the CPU at the lands (little copper circles) and make sure that there is a mark in each somewhere near the centre.
If there are any missing marks or any of the pins are obviously bent then that is your problem.

Before refitting the CPU clean off all residue of the old thermal paste and the same on the heatsink and then apply a small amount (about the size of a grain of rice) to the centre of the CPU once it is inserted in the socket.

I can check the CPU pins later today, but if this were the situation would I even have been able to run the memory check tests on this system?  DDR 1 and DDR 2 slots both work and when I install just one stick in either DDR 1 or DDR 2 or both in these slots the system posts and is looking to load the OS. 

[Dark Mantis]

Yes that is exactly my point. The pins that relate to DDR3 and DDR4 could be damaged and stopping them working.

[BillyE100]

I removed the CPU and all looks to be in good order.  Attached are a couple of pictures, not the best quality, but I believe it is sufficient.  Does this mean I should return the board?

[Dark Mantis]

I am afraid that the photos are nowhere nearly good enough! We would need a couple of close up macro photos in which we could see every pin clearly.

[BillyE100]

I know they are not the best, but can not get much better.  I checked all the pins myself and there are no bent pins.

[Dark Mantis]

Well I really don't know what to suggest next as it still could be a faulty board or CPU. Did you puchase them both from the same retailer ? If so return them both to him for RMA testing.
