Problems with Posting on Msi Gaming M5

HumbleGoatHerder · Mar 5, 2017

So, I've recently started building a new rig and recently tried to boot it up. Except when I do, the debug LED on the motherboard is consistently displaying the codes 45 to 49, which the manual tells me is an early memory initialisation.
I have tried everything, from resetting cmos, switching ram, resetting the CPU etc. and I'm still getting the same codes. Is there anything I could be missing?

Specs:
Motherboard: MSI Z170A GAMING M5
CPU: i7 6700k
RAM: 2x8gb Corsair Vengeance DDR4-3000

Try using a single stick and see what happens.

Same result as before, I'm afraid

What cooler are you using? I had the same problem and it turned out my cooler was too tight and causing the CPU to have bad contact with the pins.

The cooler master hyper 212 evo, I'll try to loosen the pins to see if that resolves it

What BIOS version do you have? There are quire a few versions that improve memory compatibility on your motherboard.

I'll be honest, I have no idea. I can only assume the latest version. How could I tell without booting up?

My 212 Evo was the source of my issue as well. If you have another cooler then try it out.

Jwpanz :

I removed the heatsink, and got the code 00, which apparently means there's a problem with my CPU, I might need to take it into a tech shop to see if that's correct

Jwpanz · Mar 5, 2017

Check your socket for any bent pins. When you said you removed the heat sink do you mean you took it out and tried to boot with no cooler? Or did you swap out a different cooler? Also, this may sound like a stupid question, but is your CPU power cable plugged in properly?

Jwpanz :

I took the cooler off and try a boot with no cooler attached. The cables definetely plugged in properly, and I can't see any bent pins in the socket

Jwpanz · Mar 5, 2017

Your motherboard won't boot without a cooler attached. It's a safety mechanism. Just lightly tighten your cooler down and try to boot.

Jwpanz :

I lightened the coolers grip down to the point that there was no pins holding the cooler on ( I had the case horizontal so I didn't need to keep flipping the case every 10 mins)

lakimens · Mar 5, 2017

I'd imagine if you boot into BIOS, you should be able to see the BIOS version somewhere in there.

I'll have to check tommorow, it's getting late. But thanks for the advice.
