I have Toshiba satellite laptop C850 with these specifications:

===============
Now I want to upgrade my memory . replace the 2GB RAM with this 8GB DDR3 :
HEORIADY DDR3 RAM
Will it work? or face problems?

I'd rather it didn't specifically mention Macbooks, but yes, that is the right type of memory.

Crucial's recommendation also includes 1.35 volt memory (DDR3L). It would save you a little power on the battery.

SO-DIMM DDR3 1600Mhz CL 11 1.5 volts

There is no guarantee that the 4GB stick and the 8GB stick will get along, but it is worth a shot. Worst case you will at least have 8GB instead of 6GB.

Thanks, I have one concern. THE BRAND? Is it good?
and what about the pins? I think I read something about that

I've never heard of that brand of memory. Likely it is a cheap chinese product. I'd stick to Crucial, Kingston, Micron, IBM, Mushkin, G.Skill, Corsair, Toshiba, Patriot, Samsung, SK Hynix, Supermicro or even PNY branded memory before trusting any of the unknown brands.

SO-DIMM DDR 3 is always going to have the same pinout, no concern there.

I have never heard of that brand, but it is pretty hard to go wrong with memory. There are only a few makers of the actual chips these days and these companies simply buy it at the bulk price, assemble them into sticks and sell them. To even work they have to basically meet a minimum standard, otherwise they wouldn't stay in business very long.

I don't recall ever hearing of fake memory. Maybe unscruplous sellers distributing used memory as new, but again, that shouldn't matter all that much.

Not really sure who to trust in the Asian market outside of the OEMs. Samsung, SK Hynix, Micron, possibly Nanya. You can certainly trust globally popular brands like Corsair, G.Skill, Kingston

Even if a reputable chip maker is sourced for the components, there can still be very questionable quality and implementation in other areas of the memory module assembly process. I would not go with an unknown, questionable brand unless it was a last resort or the budget absolutely dictated it. I always recommend going with a product that you pretty well know what you are getting instead of rolling the dice on a surprise.

I don't believe that model uses 8GB DIMMs.
It supports
Slots: 2 (2 banks of 1)
Maximum Memory: 8GB

That would be two 4GB modules. I would recommend using:

And yet Crucial themselve say yes
