y550 - kinds of memory, maximum bandwidth

Hello!

It's me again. Earlier I got problem with an unknown driver, but it was solved. Now I would like to improve performance of my:

 

Lenovo IdeaPad Y550

Intel Mobile Core 2 Duo P7350

KIWB1 PM45 rev.07 82801IM (ICH9-M) rev.03

2x 2GB DDR3 Samsung (by CPU-Z)

Memory max bandwidth (by CPU-Z): PC3-8500F (533 MHz)

NVIDIA GeForce GT 130M

 


I give the main components of my notebook to better recognize what is this a model. I would like to increase amount of RAM. From what I read in lenovo page I can have max 8 GB RAM. Ok, I get it. I read about choosing memory according to maximum bandwidth and that which CPU-Z shows me is above. But I wonder what this F mean? If that what I read from superuser.com is true, then I need to look for the same bandwidth, with F at the end. But I'm not sure. That is why I please for support.

 

What is the meaning of s, f or u and what are the difference between these letters?

 

Second question, if we can solve problem above, is about maximum bandwidth. I read some topics in this forum and from one I got page from kingston where are shown memorys. So I choose my notebook and see that : kingston memory. From this page I can see that maximum bandwidth I could choose to my new RAM is 1333MHz. But is this true? It would be nice to have more efficient RAM's, I have now 1066MHz but in lenovo page I have not noticed such informations.

 

Can I have RAM's with maximum bandwidth 1333MHz?

 

Regards,

Krystian Hoppa

According to Crucial this should be compatible:

If this is the only way to find it out, then I will accept it as a solution. But I'm disappointed of Lenovo support technicians.
Thanks jonas!

Re: y550 - kinds of memory, maximum bandwidth

So I bought at last 8GB ram sodimm (2x 4GB) - and I can say that lenovo doesn't support RAM's from "dolphin" manufacturer. What a shame .. I can't believe it, all other laptops with max 8GB memory don't have problems with that manufacturer. It works with Hynix, Samsung, Goodram .. and I think many others, but didn't tested.

 

So good manufacturer, "dolphin" .. 1066MHz cl7 .. and it doesn't work .. pff.
