Hello
My RAM upgrade (bellow) worked for a few days on my old motherboard, then all of a sudden the computer would not start any more. On rare occasion I could still get the initial UEFI splash screen, nothing more.
So I keep thinking and thinking: what kind of defect could make the RAM work for just 1 day ? Any ideas ?
Clearing CMOS and replacing the old battery did not work. Trying one RAM stick at a time did not work. I checked the RAM sticks are seated in the slots and both clamps click (the sticks are hard to fit in the slots). If I visually line them up with the old RAM, and check for size differences, nothing is wrong.
Putting back the old memory makes the motherboard work as expected again.
So maybe somehow the motherboard automatically enables the higher 1600 MHz memory speed, despite the CPU not supporting it ? Is that possible ? But how do I turn down RAM speed, since I can not enter UEFI ?
If I just buy a new CPU (i7-4790K), would it solve the problem ?
How could I re-write the SPD to lower the RAM frequency ? Do I need a payed app, or can I use Linux ?
There is a minor BIOS update from Asus for my MB, but updating is not trivial for me since I modified my BIOS to add the NVMe module (by a stroke of luck), by following a forum post that I do not remember now. I use an NVMe SSD to boot Windows, connected to the PCIe slot with an adapter from M.2 to PCIe. The MB predates NVMe drives, so I had to unpack the BIOS file and add the NVMe module from Asus to it. I should be able to do the same again, but it's been a long time. The new BIOS version only says
"Improve system compatibility. Support ALC897 audio codec" Could this BIOS update fix my RAM issue ?
