Intel Core i7-14700K Processor
On the Z790 platform, the DRAM light is frequently a symptom of Integrated Memory Controller (IMC) failure within the CPU rather than the RAM itself. Documented 'Vmin Shift Instability' causes electromigration and silicon degradation in Raptor Lake CPUs, leading to an inability to train DDR5 memory modules at rated frequencies. Replacing the CPU restores the functional memory controller required to complete the POST sequence.

DDR5 Memory Kit (2x16GB) 5600MHz
DDR5 memory utilizes an on-module Power Management Integrated Circuit (PMIC) which can fail or become 'locked,' preventing the motherboard from initializing the DIMM. Furthermore, signal integrity issues on specific Gigabyte Z790 BIOS revisions can cause training failures with certain IC die types (Samsung vs. SK Hynix), resulting in a persistent DRAM debug light.

CR2032 Lithium 3V Battery
A depleted CMOS battery can cause corruption of the Extended System Configuration Data (ESCD) or the BIOS NVRAM. This results in the motherboard attempting to boot with invalid or 'stuck' memory training parameters that are no longer compatible with the hardware's current electrical state, triggering a DRAM initialization error.
