Fixing DDR SDRAM Memory Modules' SPD Information

[Ascii2]

I want to properly set the SPD data of two modules and correct for any errors there may be.

I have two, double-sided DIMMs of DDR SDRAM modules from an unknown original source. The modules use Hynix HY5DU12822DTP-D43 memory chips. The modules' SPD data seem to have been edited and one module appears to have the EEPROM replaced. The sticker labels do not appear to be from any particular memory OEM.

I have provided a picture of the memory modules.
I have dumped the SPD data of the modules with SPDTool 0.63 and have attached them here.
The datasheet for the memory chips may be found: http://docs-usa.electrocomponents.co...tockno=6686199 .

The CPU- Z 1.64.0.x32 data from the modules:

I request assistance in determining proper SPD register vales for the two modules.

Seesh that's a tall order. Best advice I can see is to just clone the SPD off a known good similar stick.

[Ascii2]

I did not have a known good similar sick to clone the SPD data from. I did, however, find a dump from the Thaiphoon Burner software database that included most of what appeared to be the correct ODM SPD data. From that I was able to fix the SPDs. The original brand, if any is still unknown, but that is acceptable.
