Maximus IX Hero wont boot with memory slots A1/A2 populated

[lufiron]

A bad mount can warp the board or cause uneven pressure on the socket - that can cause issues with memory detection.

I had this exact issue with the Apex build I recently completed. *I kept getting error code 55 with no post. *Initially, I thought it was the memory so I tried a different kit but it still wouldn't post. I reseated the CPU and tried to see a POST with no cpu cooler and sure enough it came to life. *So what I did then was use a torque driver with an overrunning clutch set to 2.5 newton meters to torque the mouting screws of the Noctua alternating 90 degrees each screw until the specified torque was achieved. *It's been fine ever since.

This is really helpful, thanks for sharing! I will surely try it out!

The thing that confuses me the most, is that the 2nd mother I sent back to the computer shop got tested by them before replacing it, so they didn't have my watercooler installed, this is either a really pressure sensitive motherboard, or something different happened (or maybe they did used my watercooler, what do i know? haha)

Tried to boot without a CPU cooler, I'm still unable to boot.

I am having similar, though intermittent problems. I am at the "grasping at straws" stage. Are you using an external graphics card? If so, you might want to remove it and use the on-chip graphics as a test. I did this and am not having issues, but it may just be coincidental and a matter of time before the problem resurfaces.

Still code 55 if the memory is in slot A2? I assume after clear CMOS, as the CPU will get hot very quickly if not the case.

I agree that the CPUs nowadays get bent so easily. That being said, and considering that you've tried other RAM modules, I guess there's no other way other than RMAing the board.

If by external you mean a PCI-E then yeap I'm on a GTX 1080. I could try the on-board GPU but that would be more of a workaround than anything else...

Just out of curiosity what ram are you using?

I did a clear CMOS, yeap. I got a CC code and got stuck there, tried memOK! and got the same results, to be honest i didn't wait to see a 55 because i wasn't really confortable with the CPU without a cooler. I did however tried with the slots B1/2 and as ussual they did boot right away. Could retry if you suggest it.

I'm trying everything in my power before RMA, could this issue be related to the fact that the ram has leds, and somehow affect the motherboard? or in a far fetched way, the PSU? I've got a brand new EVGA SuperNova G3 850w, i mean they don't get more premium than that... but still i don't know what to think anymore.

The one thing i couldn't try yet is the CPU in another motherboard, i'll try to do that this weekend with a friend. If everything works, then i guess is RMA again for me.

I tied with two sets of RAM, GEIL and HyperX Fury, both 2x8Gb. Identical behavior for both. As I said, the problem is intermittent, so I cannot conclude with any certainty that the presence of a PCIE board is signficant. I am using the system right now with the built-in video and it is working for the present. Incidentally, this is on a Code board.
