Known Bad Configurations

These configurations should have been mentioned on HCL if they work in some situations.


Manufacturer Model Size Speed Type ECC CPU Mainboard Mainboard PCB revision Firmware Fails under proprietary BIOS Known requirements to trigger bug Failure Notes
Micron MT36KSF1G72PZ-1G6M1FF 8GB DDR3-1600 Registered Yes Opteron 6262HE ASUS KGPE-D16 1.03G Internal development version of coreboot Yes Two DIMMs on one channel (i.e. a DIMM in at least one black slot) Severe memory corruption; coreboot goes into a reboot loop and the proprietary BIOS hangs on starting its PXE ROM(s). Leaving all black slots empty restores normal operation.
Micron / HP MT36JSF2G72PZ-1G6E1LG (HP: 672612-081) 16GB DDR3-1600 Registered Yes Opteron 6276 ASUS KGPE-D16 1.03G Libreboot 20160907 No More than 2 DIMMs per CPU Cannot boot (works fine with proprietary BIOS).
Hynix/Hyundai HMT151R7BFR4C-H9 4GB DDR3-1333 Registered Yes Opteron 6276 ASUS KGPE-D16 1.03G Libreboot 20160907 No Two DIMMs on one channel (i.e. a DIMM in at least one black slot). Crashes / Reboots (always boots).

On a side note: without proper cooling these gets really warm with Libreboot, unlike proprietary BIOS. However, the heat is not the problem but might be a symptom. (works fine with proprietary BIOS).

Micron MT36KSF2G72PZ-1G6E1FE 16GB DDR3-1600 Registered Yes Opteron 6308 ASUS KGPE-D16 1.04 Internal development version of coreboot (2017) Yes One DIMMs on one channel (i.e. the DIMM is in the topmost one orange slot, A2) coreboot cannot send MCT request and goes into a reboot loop; the proprietary BIOS also enters a (quite fast) reboot loop before the VGA port can be initialized. These modules do not work at all with either coreboot or the proprietary BIOS regardless of slot location!

Both Micron DIMMs tested fails at >64GB with two CPUs, coincident?
