Solved: Ram Advice for my new laptop (32 bit or 64 bit)?

Hi all,

I just bought a new budget laptop but wouldn't mind upgrading the memory.

The laptop is the Lenovo G40 which came with 4GB and no OS installed.

I was planning on installing Windows 7 but if I go for more ram I will need to get the 64 bit version I understand.

The processor is an i7 CPU @ 2.00GHz

Would I be OK installing Windows 7 64 bit and then adding another stick of 4GB to bring it up to 8 GB or should I aim for more ram?

I'm planning to use it mainly for web surfing with Chrome, Word, and image editing with Photoshop.

My previous laptop was a i5 with 4GB ram (Win 7 32 bit) and it would grind to a halt fairly often so I would like more power for my day to day tasks.

If you are planning on installing Windows 7 you should go for the 32-bit version,because it is a lot faster [even when yo have extra RAM] than the 64-bit versions.Also 32-bits have some limitations.
So 8GB+ ram with Windows 7 64 bit will be noticeably slower than 4GB ram with Windows 7 32 bit?

But then you say 32 bit has some limitations. What sort of limitations and do they make 64 bit a better choice?

Not sure if Pijush has mistyped or what to be honest.

If you want to have more than 4Gb useable RAM installed you must have a 64bit operating system. Personally, I have had absolutely no problems running a 64bit system and it performs better in just about every task (again from my experience) with more RAM it can use.

Which version of Windows 7 are you planning on? Different versions of Windows 7 64bit support different amounts of RAM also, see here:

However, the operating system is not necessarily the only limiting factor. There can be hardware limitations that mean it could only support up to 4Gb RAM even with a 64bit OS. Which exact Lenovo G40 is it as there may be some hardware limitations.
Thanks for the info. Its a G40-70.

According to Crucial it can take:
Memory Type: DDR3 PC3-12800, DDR3 PC3-14900, DDR3 (non-ECC)
Maximum Memory: 16GB
Slots: 2

At the moment it has 1 x 4GB stick in there, so would I need to pair that with another 4GB stick, or could I put in a 8GB stick to go with the 4GB?

8 GB(4 GB X 2) of RAM is plenty for Windows 7 64-bit.

Make sure both modules(current and new) are the same speed, voltage, etc..

Thanks. Will install 64 bit Windows 7 then.
I would definitely go with Windows 7 64-bit with 8 GB of RAM instead of Windows 7 32-bit with 4 GB of RAM.

The Home Premium or Professional version should do okay for you.

Thanks. It feels a bit slow with 4GB right now so will look to upgrade to 8GB ASAP.
