I hope you can help me here, I have spent quite a lot of time trying to achieve an answer just via google, but alas no luck.
I currently have an Acer Aspire E380 with an EM61SM/EM61PM motherboard. The system is 32 bit Vista
Currently I have the following RAM installed:
2 x 512MB (slots 1 & 3) 5300U 667MHz (this is the original RAM that came with the PC)
2 x 1GB (slots 2 & 4) 6400U 800MHz (this was a later upgrade from a few years back)
this has worked fine for years. I recently tried to upgrade to the max capacity of 4GB RAM by purchasing 2 more of the exact 1GB RAM. However, when I take out the original RAM and put in the new RAM, the system boots up and after 1 minute or so, crashes with a blue screen (check new hardware etc).
It seems to me that the motherboard is defaulted tot he bus speed of 667MHz and doesn't like the brand new RAM in slots 1 & 3.
is there anyway of changing this in the BIOS (I looked but am unsure) so that it will accept the new RAM and allow me to have 4GB?
Pull out the battery for 15 minutes and stick it back in with the RAM configuration you want to work as an end result. It might work. If you are religious, somewhere in that 15 minutes would be a good time to pray.
That may shortcut you to a good end result or it could completely waste 15 minutes, but I recently had RAM problems and it worked for me.
If you are going to surf the internet looking for solutions for that 15 min anyway, you don't really even have to monitor anything so it mostly doesn't waste any time to do this plan.
