I have had nothing but trouble with this motherboard, well, actually two motherboards. The first one I got was defective and the memory voltage would not change, even when changed via XMP or manually in the bios. I got a replacement board and it was working for a couple months and then I started getting BSOD often.
The memory I bought is on the QVL list on both G. Skill and ASUS web sites: F4-3200C16D-64GVK - It's a 64GB kit with (2) 32GB sticks. It's on the QVL IF the CPU is a 11900K (which mine is). The memory timing is: CL16-18-18-38 1.35V
After getting the BSOD, I got an RMA and put in the replacement last night. It didn't boot. It got stuck at 55 (memory not installed). I wiped the bios and I put in only one stick at a time and finally got it to boot with both sticks. It passed a Memtest with the bios set to Auto. Once I turned on XMP1 or XMP2, it would either not boot (2A - memory initialization) or sometimes 55. Twice, I got it to boot and was able to run Memtest. It failed.
So the question is - is it possible that memory is on the QVL and still NOT WORK? I'm so frustrated. I can throw in some old memory (4x8GB) and it runs fine, although slower than I would hope. Amm I just plagued with bad luck on this build or is it possible the memory that should work, simply won't. I don't know what G. Skill will do. I can not longer return it to Amazon as I bought it in November. I've literally been messing with it since then. I did get a couple months where it worked but then the BSOD came back. Replacement memory appears no better.
Thanks for the help.
