    ASUS ROG Strix Z270F won't boot with more than 8gb RAM

    Greetings.

    I recently bought all the parts for a new computer and assembled it. After putting everything together, the computer doesn't boot, can't get into BIOS.
    It refuses to boot if I use 2,3 or 4 sticks of 3200hz DDR4 RAM, however, it does boot and function normally if I use only one stick of RAM.
    When it fails to boot with more than one stick, I get a red DRAM light on the motherboard.
    Am I doing something wrong here? Do I need to update my BIOS or change settings in it? Any help would be appreciated.

    Specs:
    Motherboard: ASUS ROG Strix Z270F
    Processor: Intel Core I7-7700
    Graphics Card: NVIDIA Geforce GTX 1080TI ROG Strix 11GB (not OC edition)
    Ram: Corsair Vengeance LPX 32GB 3200hz 4x8 (CMK32GX4M4B3200C16)
    SSD: Samsung - 850 EVO-Series 500GB
    PSU: XPredator 650gm 650w

    I checked the manufacturers list and I noticed that the RAM is not there, however very similiar ram is there.

    Hello Bjartur
    Have you checked that all of your RAM are normal?
    Thanks

    Have you tested each stick individually to see if your system would post?

    Yes, every stick works as normal, and the computer boots if i have any one of the sticks in a1 or a2, but it will never boot in any dual, triple or quad configuration.
    It will not boot either if I have one stick in b1 or b2. All 4 RAM work solo in slot a1 or a2.

    Hello again.
    Here is an image of the LEDs I get when the computer cannot boot. Internal speaker makes no sound, and it cannot post.

    Upon closer inspection, it appears 2 of my CPU pins on the motherboard are bent. Should I try to bend them back into place?

    CMK32GX4M4B3200C16 doesm't appear tp be on the Asus QVL tested list for that motherboard.

    I chose F4-3200C16Q-32GVKB (also 4x8 3200) and they work fine.

    If you feel capable, yes. Bent pins often affects the memory slots.

    Hello again.

    I was checking out the pins and I took out a spyglass to take a closer look. It turns out the pinheads were completely hanging off of the pins themselves.
    Just rotating the motherboard to see it a bit better made them break off..

    I suppose the motherboard is unusable now. I'm not familiar with ASUS RMA policy, can I return this and get a new one?
    The pins were bent in such a way that its impossible it was my fault. Its almost like the neck of the pin (right under the head) was burnt.

    My initial PRIME Z270-A was bad. Bent pins and I found a solder flake jammed in the pins. I was a bit shocked that it passed Asus QA.

    I bought it from Amazon and returning it to them was the fastest. I filled out the return information completely online, said the socket was bad, and they issued a total refund even before they got the old board back. They paid for the return shipping. I used the refund to buy a STRIX Z270F instead and with Prime I had the replacement in 2 days.
