I have a Toshiba Satellite M645 running Windows 7 64bit Pro. The specification states that this particular machine can use up to 8Gb of RAM.
The specs state the RAM is:
DDR3 1066MHz (PC3 8500)
- I purchased two 4Gb modules and...
- Shut down the notebook
- Removed power cord
- Removed battery
- waited 10 seconds...
- removed and replaced (carefully and grounded) the SODIMMS respectively 2Gb with 4Gb.
- Replaced battery
- Plugged notebook back in
Windows 7 Freezes on logo screen:
Starting Windows...
But the logo never appears and it just hangs for a long time... better than 15 minutes and I finally got tired of waiting. This is the ONLY behavior I have been able to get when the 4 Gb memory modules are present.
The BIOS recognizes all 8 Gb (8192 Mb) and the same SODIMMS work in a 64 Linux system without any issues. When I replace the new 4Gb modules with the original 2Gb modules, Windows 7 starts fine.
Please advise.
