So i bought a macbook pro and i was wondering if i can max out the stock 4gb of ram to 12gb of ram, so i search in ebay and i found this two memories and i was wondering if i can combine these two

8gb stick

4gb stick

I would just stick with either 4GB, 8GB (4GBx2) or 16GB (8GBx2). Everything i have read says to stay with matched pairs...ie 2GBx2, 4GBx2 or 8GBx2.

I would buy 8GB (2x4GB) or 1 8GB (1x8GB) for now and wait until you can afford another stick or until they come down in price. Matched pairs provide the best compatibility and the fastest speed.

Agreed on the matched pair suggestion - I don't think it's worth going for 12 GB of RAM, so either go to 8 GB (2x4GB or 1x8GB) or go all out for 16GB (2x8GB). RAM is relatively cheap these days so I think it would be a worthwhile investment for your machine. But whatever you do I highly recommend staying with the same supplier/vendor and not mixing modules from different manufacturers - one less potential variable to worry about.

thanks for the answers, im not a graphic designer or something like that i just want to have more ram because i like messing with virtual machines ang games but it seems that the matched pairs would be a problem, and searching on the internet i read that that the CMSO8GX3M1A1333C9 memories causes kernel panics and stuff like that

should i buy this ones:

Kingston Hyperx
http://www.ebay.com/itm/Kingston-HyperX-8GB-2-x-4GB-204-Pin-DDR3-SO-DIMM-DDR3-1600-HyperX-Plug-n-/290633114696?pt=LH_DefaultDomain_0&hash=item43ab156448#ht_2296wt_1012
(for the people that have installed this memories does the 1600mhz improve the performance and speed and its true that drain the battery faster?)

or should i buy the 16gigs ram modules

(people who have installed the 16 gigs modules: Does the performance/speed increase with more memory or only works to have more programs open?)

No! First of all...way to much money...

Matched pairs should not be any problem at all. Go to www.crucial.com and fill out the wizard (apple->macbook pro->model. 8GB should run you less than $50. If you feel you need 16GB the price goes way up, but the wizard should give you all the answers you need.

Both the two posts above are good RAM.

If you don't plan on buying it in the near future, newegg.com usually has sales ranging anywhere from $25-35 for good quality RAM.

I'll disagree with the posters here and say that matching memory modules was probably wise in years gone by for the extra performance - you are highly likely to ever notice these days. If you need the extra RAM then the performance gained by that far outweighs any nominal speed drop due to dual channel.

I run 12GB currently in my i7 MBP for running Virtual Machines. I didn't go with 16GB as it was too expensive but 8GB on Lion for my work just doesn't cut it. The machines flies now it has enough room to breathe.

I'll add at this point though that an SSD is the best upgrade by far you can make so if a choice between 8GB + SSD if that is enough RAM and 12 or 16GB then SSD is the way to go.

Agreed, I don't think people will notice too much of a performance penalty, but by the same token, why introduce that penalty when you can avoid it.

so going for the 12gb of ram is not a bad idea, i mean the performance will not decrease because they are no matched pairs?

people that have installed 12gb: does the ram work well in your macbook pro ?
