Hey guys,
Hopefully someone can share their opinion with me on an issue im having with my new build. Full specs below.
What's happening is, when I populate the 3rd and/or 4th DIMM slot on my motherboard with a RAM module, the board fails to post. The system turns on, then off, then on and does this for a short time, then the DRAM LED on my motherboard remains lit. The system remains powered on, however it doesn't POST.
Currently I have the system posting and booting up successfully with RAM installed in the 1st and 2nd DIMM slots. Obviously this means it's only running in single channel however the system does appear to be stable. On this board you use slots 2 and 4 for dual channel operation when only using two sticks of RAM, but this fails to POST due to the problematic 4th slot.Currently, the only way to POST successfully is to populate slots 1 and 2 (or just 1 or just 2).
I have read this can be a sign of bent pins on the CPU socket, so I went ahead and removed my cooler to double check, but there are definitely no bent pins. I took great care installing the CPU (this isnt my first build) so I would have been surprised if I had bent the pins.
I have 4 8GB sticks of Corsair Dominator RGB RAM, and no matter which ones I use, the result is the same. Is it possible I have a faulty motherboard? The RAM is running with the correct XMP2 profile in the BIOS. I also made sure to update to the latest BIOS.
I would welcome any thoughts on this issue, and please let me know if I need to supply any more information.
Thanks!
