Incompatible

I bought some new RAM for a small PC I was given and took the feeble 2 GiB that was in out. My plan was to add it to the 2 GiB I had in another system, taking that to 4 GiB which would be it's maximum and make it a bit more useful. Sadly it was not to be, the PC would boot up with either DIMM installed, but not both at the same time. I can now spend another €10 and buy some ancient RAM, or not bother...

Still way behind on my back blips...
