I have recently begun to consider a RAM upgrade to my laptop. It's an Acer Aspire 5610 (5612AWLMi) which currently has 2 x 512MB sticks installed running at PC2-5300 (667 Mhz). I have been confused by ideas whether the laptop supports 2GB or 4GB maximum. Acer's own eSettings say that it maxes out to 2GB but then I have seen conflicting information which says it can go up to 4GB. It seems the Intel chipset used in this particular Aspire model is an i945GM which goes up to 4GB. Is there anyone out there who has this model of Acer and can tell me whether this system definitely does or doesn't work with 4GB. I have updated to the latest BIOS version of 3.60.
Also the Intel datasheet states for 945GM - Maximum Memory supported: up to 4 GB at 400, 533 and 667 MHz. If I used DDR2 800Mhz RAM on this chipset would it just fall back on 667 speeds (which I believe it should) or not actually work?
