I have a laptop with 3 gb RAM DDR3-1066/PC3-8500 of SODIMM form factor. Now I need to extend my laptop RAM. But when I searched online stores it has found that presently the RAMs come with DDR3-1333/PC3-10600 configuration. Does this configuration supports my laptop?? I need to know more about this...

higher rated ram 1333 will able to run lower speed ram 1066 (and below) but not the opposite.... (as long as they still same type DDR3 SODIMM)

in fact most the mobo will automatically setting it to lower clock when installed....
also if u are going to run dual channel make sure u got identical ram (dual channel set ram)..

the negative is higher rated ram is price higher than it's lower rated ram...

Does this mean that to upgrade my laptops RAM, I need to have DDR3-1066 ram itself. Purchasing DDR3-1333 will be of no use for me? I didn't find any DDR3-1066 RAM on the online stores to buy for my laptop. Can you please explain it more clearly.

it's means u can use the 1333 ram in your 1066 laptop....

but lose in price since 1333 is priced higher, but since that only one they had then i see no choice then...

second are u just adding another stick of ram to the laptop (1 old ram + 1 new ram) or u changing both ram (2 new ram)? I assume your laptop has to 2 ram slot

My laptop has 4 RAM slots. Slot 1 has 2 GB. Slot 2 is Empty. Slot 3 has 1 GB and slot 4 is empty. Is there any problem in adding the new RAM of 4 GB DDR3-1333 to the Empty slot 2, with the 2GB in slot 1 and 1 GB in slot 3.
Then I will be having a total of 7 GB RAM for my laptop. Is it possible by this way??

so u already mix match the ram.... since it a laptop with that kind of configuration... I'm not quite sure (laptop bios is harder to tweak..)
I would said 90% it will work... can the shop let u tried first?

if it somehow don't work u may need to try this configuration 1G,4G,2G,0 or 2G, 4G,0,0 (ditch the 1G)... or other configuration...

btw u need a 64 bit OS to able use more than 3 Gb ram...

I'm planning to install the RAM by myself. Now I'm using 64bit windows 8.1. I have heard that 32 bit OS does not support more than 3 GB. Before purchasing the RAM, I have to make sure that DDR3-1333/PC3-10600 configuration works for my laptop smoothly without any problem. That's why I have asked it. Anyway, thanks for helping me out. Are you sure that DDR3-1333 RAM works with my DDR3-1066 RAM.?? If the answer is yes, then can you please suggest me some good Brands for the DDR3-1333 configuration to buy for my laptop.

In general term, then YES... the higher rated ram will always support lower ones...

they test the ram from the slowest/lowest speed to the top...
if the ram failed in higher speed test they just sold it as lower speed ones and lock the speed (that the simple idea)..

edit: I'm cannot suggest brands, all of my notebook rams have different brands each stick and i cannot see any difference in them...
(There samsung, hynix, there one original HP, also some local brand V-Gen)
