Currently building a new MITX system and having a reboot loop on boot. I've narrowed it down to being RAM related.

Motherboard: https://www.overclockers.co.uk/giga...1151-ddr4-mini-itx-motherboard-mb-536-gi.html

RAM: https://www.overclockers.co.uk/cors...hannel-kit-black-cmk16gx4m2b30-my-445-cs.html


  • Stick 1 in Channel A boots to bios. (Slot 2 empty)
  • Stick 2 in Channel A boots to bios. (Slot 2 empty)
  • Stick 1 in Channel B does not boot to bios. (Slot 1 empty)
  • Stick 2 in Channel B does not boot to bios. (Slot 1 empty)
  • Stick 1 in Channel A and Stick 2 in Channel B does not boot to bios.
  • Stick 2 in Channel A and Stick 1 in Channel B does not boot to bios.

Unless I'm being silly, I've tried every RAM combination and the RAM shows as compatible on the Gigabyte website so I don't think it's that. I've also tried updating the bios from F6 to F7 and it's still looping.

I have nothing apart from a monitor and keyboard attached (i.e. no graphics card (using on-board as I was ruling out graphics card) and no hard drives attached).

Unless there's a setting I don't know about, it's looking like Channel B is faulty as each individual stick boots fine in Channel A? Anything else I could try or check?

That is weird, because the memory is in the supported memory list.

Go into the BIOS with just one stick, set the timings manually as per specs, then try the second stick of RAM.

I've tried that and still no luck. Also tried with XMP on/off, clearing the CMOS and using a different +12v cable in case it was that.

Tried running a few rounds of memtest on each stick individually?

I'll give that a go but fairly certain it's not the RAM sticks at this point - both seem to work individually, it's only when they're in Channel B does it not boot up. At least we'll be able to rule it out if it is them with it.

I've tried everything I can think of now. Fortunately I can't actually use the system for a week or so yet as I'm still waiting on a couple of parts but it's frustrating!

Check the cpu pins on the motherboard socket to see if any are bent, overtightened aftermarket cpu cooler can cause problems.

Good call! I seem to remember hearing about heatsinks being put on too tight causing problems with memory.

Yep - great shout. Took the CPU off and there's two bent pins on the left and one in the middle. I've had a quick go at straightening them and it does now detect/boot with two RAM sticks, but seemed to freeze and have issues when I turned on XMP - might be a case of one of them not being straight enough.

I've taken it out the case so I can have a better look and see if I can fix it otherwise not sure what my options are.
 
Forget xmp for now.

Take your time straighting the pins get a magnifiying glass and a pin so you can be more precise. I had problems with bent pins and after i strightened them the memorry would not run in dual channel mode.

Bugged me for ages so i tried again to straighten them perfectly, eventually one pin snapped, so be careful.

Good luck and lets us know if you sort it.
 
I'll see if I can pick one up tomorrow from a supermarket. Here's hoping it's fixable - thanks a lot for the pointer!
 
Managed to pick up a magnifying glass and had a go at straightening the pins. It's now detecting both sticks of RAM and enabling XMP works.

I'm just copying across some benchmark/stress tools to see how it handles those but looking good so far!
