Hacked on SO-DIMM Slot used to be Value a Shot

Discovering unpopulated pads on a circuit board is ceaselessly an indication that the instrument in query has some untapped doable. Those clean spots at the board may well be left over from options or features that had been deleted from the design, or most likely even constitute an non-compulsory improve that wasn’t put in in this explicit specimen. So we definitely perceive why [d0rk] used to be interested by the empty SO-DIMM footprint he lately discovered on a computer’s motherboard.

The price range Celeron system shipped with 4 GB of RAM put in in its unmarried socket, a scenario [d0rk] was hoping he may just make stronger upon with the addition of a 2d module. However may just it in point of fact be so simple as pulling the socket from a lifeless motherboard and soldering it into position? Would different parts wish to be added to the board? May the BIOS take care of the sudden improve? There used to be most effective one technique to in finding out…


Room to develop(*(*19*)*)

To start with, it gave the look of the affected person didn’t live on the operation. However an in depth glance exposed that the facility button had if truth be told gotten broken someplace alongside the road. As soon as [d0rk] mounted that the system began up, however sadly the working machine didn’t see the additional RAM module. Even after upgrading the BIOS, the pc remained oblivious to the extra reminiscence.

When he went again in to investigate cross-check his solder paintings for shorts or unhealthy joints, crisis struck. For causes that aren’t straight away transparent, the pc not begins. Even after pulling the transplanted SO-DIMM slot off the board completely, [d0rk] says it gained’t make it during the self-test. Clearly a disappointing conclusion, however we appreciate the hassle he put into the try.

Whilst this reminiscence improve didn’t move consistent with plan, we’ve noticed sufficient good fortune tales through the years to stability it out. From previous wi-fi routers to state of the art video playing cards, numerous units have won a reminiscence spice up courtesy of a soldering iron and a gradual hand.
