Hi everyone, i'm trying to edit my RAM sticks SPD eeprom using thypoon burner. I already physically disconnected the write protection pin on the SPD eeprom following the datasheet of the eeprom manufacturer, the problem is that SPD write is disabled by default in bios. No options are available to enable it in the interface. I already tried to mod the latest official MSI bios following this guide (softnology.biz/tips_spdwritecap.html) from Thaiphoon Burner themselves, patching the "SmBusPei" PE32 image, but the procedure didnt work as Thaiphoon Burner still detects the bios write block. Can someone please edit the bios for me in order to disable the SPD write protection? Thanks in advance. Latest official bios for MSI z97-g43 attached (download.msi.com/bos_exe/mb/7816vHB.zip)

So on that forum that you saw that... does it state that your motherboard model has that string/variable in the bios?
A quick search for "SPD" string with the AMIBCPtool 4.55 didnt showed nothing related SPD "Write Protection" strings/variables.
If its there then its possible to change, if not present then nothing to do about that with conventional methods. And dont ask if it can be added as new string...

The AMIBCPtool is valid for Aptio IV core bios gen, sometimes it can perform the changes in bios, other times it fails and needs manual hex edit like the recent Aptio V bios gen.
