I have an old HP Pavilion dv6 Series
(model dv6-1140ej).
It has 2GB of RAM in 2 sticks. According to the specs, it supports 400Mhz DDR2 memory.
I would like to increase the amount of RAM I have.
Someone told me faster memory sticks (say 800Mhz) cannot be used when only 400Mhz are supported.
This is a bummer, because for some reason 4GB of 400Mhz DDR2 costs about 3-4 times more than a modern DDR2 stick with the same size.
Is this really the case ? Can't a memory stick work in a frequency lower than its optimal ?
Here is the CrucialScan results:
And now it's even weirder, with the help of "HP Support Assistant" here are the memory details:
1GB 7F7FFE0000000000 800MHz (X2)
Can I really use DDR3L-1600 SODIMM for this old laptop ?
