Parts:
MB: Z68 Extreme3 Gen3
MEM: Corsair Vengeance 2 x 4GB (tested and working)
PSU: Corsair TX 850W
CPU: i5 2500K
GPU: GTX 580

Everything works, but:

If one or two of the memory modules are placed in either slot DDR3_A1 and/or DDR3_A2 I get error code 38 which is Post-Memmory North Bridge initialization:


Only when memory modules reside in either slot DDR3_B1 and/or DDR3_B2 it boots ok with no error messages and everything in BIOS looks right.


Same exact problem as this guy: http://forums.tweaktown.com/asrock/4...tml#post407347

Anyone have a clue what's going on?

Have Asrock possibly printed wrong labels on the memory slots (confused the numbering)? Which ones are supposed to be populated first according to the user manual? If you have a chance, borow two more DDR3 strips from a friend and populate all slots. See what happens. If the RAM is then fully recognized and the system boots - it would confirm my idea above... If not, well, that would be a hint that the A-group of slots may be faulty. In that case I'd rma the board. Or check if there is a BIOS update that might sort the problem.

It works now:

I removed the CPU, inspected the socket pins for dust or damage/angles, they all looked like they should, I reseated the CPU, and it works now. I have no idea why that fixed it.



Since the thermal compound was brand new air bubbles shouldn't be that much of a problem right? I didn't remove or reapply any of it. The temperatures are great exactly as they were before. 34C.

Was the CPU cooler really completely down on all four mounting points? Unless the CPU itself was not properly lined up inside the socket I can only imagine unevenly applied pressure to be a reason for that...

Coming to the thermal compound - I'd strongly recommend to be very careful about not redoing it. At least do yourself a favour and thoroughly stress-test while you're closely monitoring the temperature

Anyway, glad to see that you were able to sort it out by an easy and inexpensive solution.

cheers!
