I recently purchased RAM chips for my daughter's Sony VAIO PCG-K13. The laptop came with (2) 256 chips and I needed to upgrade to 1 gig in order to install Adobe's new Creative Suite. I purchased (2) 512 chips that are supposed to be compatible. The laptop will only recognize 1 chip at a time, so I still only have 512 RAM and am unable to install the new software.
I've checked both chips in both slots. The chips seem to be working. The slots seem to be working. After about 4 hours with tech support from Sony, the chip maker, and the vendor where I got my chips, I'm still no where. I updated the BIOS this morning, but it still only recognizes 512 RAM. Have any suggestions?
