My notebook is TravelMate 6291. There are 2 slots Memory (RAM) installed at this time, the first slot is 2GB (Visipro DDR2 800) and the second slot is 1 GB (Visipro DDR2). When I replaced the RAM 1 GB to Visipro 2 GB DDR2 6400 (Total RAM = 4GB), this notebook can not boot into Windows 8 64 Bit. Whereas in reference website (http://www.cnet.com/products/acer-travelmate-6291/specs/) informed that the maximum RAM this notebook is 4 GB.
My notebook BIOS version is v1. 3109. I find a newer BIOS update drivers 3117 for this notebook in http://www.acer.co.in/ac/en/IN/content/drivers. If I update the BIOS driver from 3109 to 3117, my notebook issue is resolved? Thank you for your help.
