Decided to upgrade my NGC-1 to 8Gb. A time ago I bought a Crucial SODIMM but it wouldn't work in the NGC-1; the computer wouldn't even boot to the BIOS.
So I reckoned that this SODIMM for some reason had a defect. So I bought the 8Gb. version of the 4Gb. SODIMM (Samsung) that was installed from the factory, but it also wouldn't work at all.
Upgraded the BIOS to version 1.3 and still no success. Took the plunge and upgraded to BIOS 1.7 and lo and behold... it works.
So, that is one thing that BIOS 1.7 changed (at least for me). Happy camper now. Upgraded to 8Gb. RAM and 256Gb. SDD.
