i5-2500K not seeing 4 DIMMs worth of memory

Hey folks,

I recently ordered an i5-2500k and a new ASUS motherboard. I got it all hooked up and turned out that the PC would not POST with 4 DIMMS worth of memory in. I immediately figured this was a MoBo issue and replaced it with an MSI Z77A-GD65. Upon hooking everything up, I found the same issue to be prevalent.

So, thanks to my stubbornness, I look up compatiable RAM and sure enough, mine is not listed as compatible. So, I pick 16 GB of RAM that is compatible install all 4 DIMMS and I still cannot POST. I can post with 2 DIMMS (8GB) fine.

I contacted MSI who told me that it was because there was a bent pin on my processor. I unseated the thing and checked it out and it looks clean as a whistle. MSI will no longer offer any support. This thing is less than a month old. I'm at a loss here and was hoping someone in the Intel community might be able to steer me in the right direction.

PC Specs:

i3 2500k

MSI Z77a-GD65 Motherboard

gSkill F3-12800CL9D-8GBRL RAM

800 Watt Corsair PSU

EVGA 570

Hello Josh,

Your i5-2500K supports memory up to 1333 MHz at 1.5v as shown below:

The Gskill memory you have is rated at 1600 MHz so it does not seem to be compatible.

You may also try to reset the BIOS and update it.

Besides that, if there is a chance the socket in the motherboard has bent pins you may need to swap the motherboard or the processor with another one in order to determine the faulty component.

Hey Joe,

Turns out that upon further inspection, the pins on the motherboard socket are bent to heck and back. I am surprised I was able to get it working at all. I am sending it back for return today and purchasing a different one.

Thanks for your help~!
