I'm having a problem that I can't seem to narrow down with an Asus Prime X299 Edition 30 motherboard. The configuration is as follows:
Asus Prime X299 Edition 30
Intel i7-9800X CPU
Asus "Thor" 1200 PSU
EVGA GTX 680 (placeholder known working)
3x Intel M2 SSD6 1TB NVMe drives
The system powers on fine, all the onboard displays come on and the fans work. During the initial posts I received a QCode 53 (Memory initialization error or invalid memory). I pulled out the first memory, cleared CMOS and put the second memory in and this time got into the bios. However, it only detected only one of the 2 memory 16GB DIMMS (Corsair Vengeance DDR4 3600). Then put the first set of 2 RAM modules (G.SKill Ripjaws V 32 GB F4-1600C18D-64GVK). Again, it only detect 1 of the two modules. The recommended placement for this motherboard is put one DIMM in the C1 slot. This worked fine. When I added the second DIMM to the recommended A1 slot I got the QCode 53 error again. It turns out that the C1-C2-D1-D2 are working fine but the A1-A2-B1-B2 are not being recognized in those slots. The same memory works fine if both are installed in D1-D2 at the same time. I don't have enough RAM at this point to populate all 4 slots on the one side.
I contact ASUS but the board is six months out of warranty and they now treat it like a leper. However, I did some digging and found out two things. First the i7-9800X only supports 128GB (the i9-10989XE supports 256 in this platform). Could the CPU be shutting off half the RAM slots? That doesn't make sense to me. The only other alternative is that the motherboard has multiple dead DIMM slots on one side (something I've never seen before). This is a rare motherboard and I'm fond of it. Any suggestions for possible fixes, repairs or possible ideas. I'm reluctant to buy another processor but that is probably the next logical step if I can't find out if the motherboard is bricked.
Thanks for any/all ideas.
