Thanks for the reply - I'm guessing in that case that if there were 4 memory slots it would recognise 16GB, but as I only have 2 and there's a 4GB limit on each slot then 8GB is the practical limit.
It runs perfectly well on 4GB but I'm running Vista in a VM so it does noticably slow down...
I have an HP dv6-6052ea laptop with an i7-2630QM CPU and am looking to increase the amount of memory I have, hence my reason for downloading your software.
HP state the maximum memory is 8GB but it's not clear if that's because of a hardware limitation or just old information because nothing...
