Onboard memory utility

BIOS work for onboard memory (DDR4 / DDR5 and others): change the memory size, inject SPD data, disable onboard memory, extract SPD, with checks.

What it fixes

Onboard memory chips were replaced with another size / part and the BIOS memory data must change
Onboard memory is bad: disable it and boot from a memory module
You want to read the SPD data out of the BIOS

Log in → Online tools → choose “Onboard memory utility”
Upload the full original BIOS dump; to inject SPD, also upload an SPD data file
Pick the new size (density) and tick what you need: disable onboard memory / extract SPD / APCB check / SPD CRC check / part name check
Download the processed BIOS and write it back

The full original BIOS dump read by a programmer; optional: an SPD data file

Note：After disabling onboard memory a memory module is needed to boot. Back up the original BIOS before writing.
