Memory

BAD_POOL_HEADER

Pool manager detected corrupted data in memory. It could be the RAM or the driver.

Memory

XMP-INSTABILITY

Activated XMP/EXPO profile causes instability or non-booting. This usually traces back to RAM incompatible with board, need for higher voltage and BIOS bug.

Memory

RAM-NOT-DETECTED

Motherboard doesn't recognize RAM - reports low memory or won't boot. Typical causes include module incorrectly inserted, oxidized contacts and defective DIMM slot.

Memory

RAM-ECC-ERROR

The ECC memory detected and corrected the error, but there is a risk of an uncorrectable error when retrying. Common triggers are aging of RAM modules, cosmic Rays, electrostatic discharges and unstable power supply.

PAGE-FAULT-BOOT

BIOS/UEFI detected a fatal page fault during operating system startup. Windows won't load.

Memory

SPD-CORRUPTION

The Serial Presence Detect (SPD) chip on the RAM module has corrupted data, the system does not know what timing and frequency to set. It sometimes comes down to SPD read/write voltage failure.

Memory

SPD-CHK-ERR

The motherboard cannot read the timing from the memory module. It's most often caused by poor quality CPU controller, frequency too high and dust in slot.

Memory

BNK-INT-ERR

Communication problem between the front and back of the memory module. The usual suspects are different modules in one board, poor quality CPU controller, frequency too high and dust in slot.

Memory

XMP-BOOT-FAIL

Memory cannot run at factory overclocked values. Typical causes include different modules in one board, poor quality CPU controller, frequency too high and dust in slot.

MEMTEST-ERR-8

Memory diagnostics detected a hardware defect in the memory cell. Common triggers are different modules in one board, poor quality CPU controller, frequency too high and dust in slot.

Memory

VDDQ-U-VOLT

The modules lack the voltage to maintain the set frequencies. It's most often caused by poor quality CPU controller, frequency too high and dust in slot.

Memory

1T-CMD-FAIL

The memory controller does not have time to process commands with a delay of only 1 clock. Common triggers are different modules in one board, frequency too high and dust in slot.

ECC-LIM-EXC

Server memory is fixing so many bugs that it can't keep up. It's most often caused by different modules in one board, poor quality CPU controller, frequency too high and dust in slot.

ROW-HAM-DET

Dangerous charge spillage between memory cells noted. It's most often caused by different modules in one board, poor quality CPU controller, frequency too high and dust in slot.

Memory

DCH-ASYNC

Although the memories run in Dual-Channel, they are poorly matched, which limits throughput. Typical causes include different modules in one board, frequency too high and dust in slot.

PIN-OXIDATION

Contact with the socket is broken due to dirt or oxidation on the pin. The usual suspects are different modules in one board, poor quality CPU controller, frequency too high and dust in slot.

Memory

REF-TIMEOUT

Memory cells have lost their charge before the next refresh cycle. The usual suspects are different modules in one board, poor quality CPU controller, frequency too high and dust in slot.

Memory

GEAR-MD-FAIL

The motherboard cannot run stably in split controller frequency mode. It sometimes comes down to dust in slot.

Memory

SUBTIM-CORRUPT

The board set too aggressive sub-timings (eg tFAW, tRRD). The usual suspects are poor quality CPU controller, frequency too high and dust in slot.

Memory

DDR5-PMIC-TMP

The Power Integrated Controller (PMIC) on the DDR5 memory has overheated. This usually traces back to different modules in one board, frequency too high and dust in slot.

Memory

IMP-CAL-FAIL

The motherboard is stuck in a loop while calibrating the memory signal impedance. The usual suspects are poor quality CPU controller, frequency too high and dust in slot.

MCE-MEM-READ-ERR

The processor detected an unrecoverable error while reading data from memory and wrote it to the MCE log. Common triggers are physically damaged RAM module and unstable XMP/EXPO profile.

RAM_MEMORY_LEAK_SYSTEM

The system kernel's non-paged memory pool expands continuously without releasing memory, consuming all physical RAM and causing severe freezes, micro-stutters, and eventual crash/BSOD. The usual suspects are faulty…

DRAM_POST_TIMEOUT

The motherboard BIOS takes an excessive amount of time training the DDR5 memory channels on boot, eventually timing out and reporting a POST failure or resetting the memory frequency back to 4800MHz. See the…

DOUBLE_FAULT

DOUBLE_FAULT (Stop Code 0x00000008) occurs when the processor generates an exception while already handling an exception, or when the exception handler itself raises an exception. This is a catastrophic kernel state…

RAM-DUAL-CHANNEL-FAIL

The system is operating in single-channel memory mode instead of the expected dual-channel configuration. Dual-channel mode doubles the effective memory bandwidth by using two RAM channels simultaneously.

ECC-MEMORY-ERROR

Error-Correcting Code (ECC) memory has detected a bit error in RAM. Correctable single-bit errors (SECE) are automatically fixed by ECC logic, but uncorrectable multi-bit errors (MECE) cause system crashes.
