Thaiphoon Burne is the most popular and probably the only tool for modifying the spd.bin. It has many built-in templates and you only need to select the speed, clocking, and voltage you like (e.g., DDR3-1688/DDR3-1333 and CL10/CL11 and 1.35V/1.5V) and it will do all the rest calculations and generate the spd.bin for you. Then, the only thing you need to do is to flash the spd.bin to the spd chip on the ram, and reboot, and your ram stick is overclocked.
Unfortunately, it is only available on Windows. So I have one harddisk loaded with Windows 7 and Thaiphoon Burne specialized for this work.
I haven't found any linux software can do this unless you calculate and modify the spd.bin by hand. (If anyone found one let me know)
Cool - I never knew about that tool. Seems like a good investment if the goal is to generate an spd.bin from scratch.
Sebastien - What are you trying to do, exactly? If you only need to change one or two parameters, then a hex editor and a calculator should be sufficient. The relevant specification for SPDs is JEDEC Standard No. 21-C Annex K for DDR3 and Annex L for DDR4. (you'll need to register with jedec.org to download the specs)
