Upgrading from 3GB to 4GB

I'm planning on upgrading my Sony VAIO VGN-FW230J RAM
it currently has 3 GB
and I would like to remove the 1GB module and replace it with a Kingston 2GB one;
Will it matter if my two RAM modules are from different makers?

 

no i don't think so as long as there the same type of memory

 

No, it does not matter. Are you running a 32bit Vista or 64bit? If it is 32 bit, then do not bother with the upgrade, because 32bit Vista only recognizes a maximum of 3GB of RAM.

 

That is a easy fix, just pop in a Vista install disk and install the 64bit version.

 

And have to reinstall all your programs, backup/restore all your data, etc, etc. Not so easy, only do that if you really need 4GB.

 

As they said, it will work with any other manufacturer.

But, what do you need the more memory for? If you don't really use any application that needs and uses it all, it don't see the purpose at all, as 1GB more system ram won't be noticeable overall, if you're not doing anything that really needs it that is.

And if you're running 32bit OS then you have to reinstall everything, that's more pain than gain.

 

vista will see 3.5gb but i would upgrade if i were you make it your lappy more future proof

 

Any 32bit OS will show anything from 2.8 to 3.5GB depending on what laptop you got, it's not the same on all!

 

??? he didn't say anything about his OS not being 64 bit, he's been here for 50 post i'm sure he should know about the computer seeing the memory based on what os bit you have

 

The only one is BamAlmighty that said pop a 64bit disc in, everyone else said " IF you have 32bit" None said he has 32bit nor 64bit. So we're just saying in case he has a 32bit OS.




And don't be sure on that 50posts is enough to know that, i know a guy here that recently made a thread about this, he had 2300posts(!!!) and didn't know this + alot more... hehe (see here http://forum.notebookreview.com/showthread.php?p=4520313#post4520313 )

 

well i did say should

 

Yes I was wondering the same question I have 2gb and a 1 gb stick. So if I put in another 2gb stick will it work. Because they are two different companies.

 

Doesn't matter if they are two different companies, it will work.

 

Yes it will work if your laptop accepts 4GB (2x2GB), this question has already been answered in this thread, thank you.

 

What happens if they have different timings. The one i have has a cas latency of 6 and the one I WANT to get has a cas of 5. So what will happen there.

 

All memory modules has to comply with the JEDEC standard, so no problem there. One memory module will just use follow the other, so it should not be a problem. But try to get one which has about the same as you have atm, just in case. Though the slower memory will as said be the one that tells the fsater memory to run in a slower latency. Lower latency = faster.

 

no

we have a Dell D630 that has 2x1GB DDR2 modules from different manufacturors .. no problems.

 

haha
sorry I didn't mention
I'm using windows 7 64 bit edition
thanks for answering my question

 

1. It's rare for me to be using two modules from the same manufacturer. They all comply to the same basic specs.

2. There will be a small boost to the memory performance because 2 x 2GB will give full dual channel memory access while 3GB is pseudo dual channel.

3. Task Manager is reporting 3620704 K of physical RAM on my Dell E6400 (32-bit XP).

thanks mates!!!

 

Theres a program that allows vista to see 4 gigs.

 

What's the use when you can't utilize it all anyways? I hope you mean vista 32bit. AFAIK Vista 32bit will show 4GB without any program, it did on mine, but i couldn't use more than 3GB anyhow. So it doesn't matter how and which app will show you 4GB as a 32bit OS is limited.

 

Theres a program called ULTIMATE WINDOWS TWEAKER that allows vista 23 to see 4Gbs.

 

So?

 

What do you mean so.

 

Maybe what i wrote to you in my previous reply?

 

Yes but 32 cant use 4Gb right .

 

Yes because 32bits is only limited to 3gbs of ram. Theres so math involved but I forgot

 

Look, there is no way that a 32bit operating system can physically address 4GB of RAM. Any program that claims to do so it a hogwash scam that is either trying to fool you, take your money, or both.

 

But if you saw it for yourself...

 

Hi fluffboy, I like your avatar,could you please tell me where to get it. Thanx.

 

you should pm him instead of replying in a thread when you get 15 post

 

No, it isn't. The amount of usable memory in a system varies with different hardware configurations.

It can, assuming a hardware configuration you're not likely to use, or, much less, want to use!

 

Thanx. Will do.

 

Exactly, so why do you even post about that application when you know this? There is no application that will change that fact.

 

The maths says that a 32bit addressing system can address up to 4GB of memory, however the system RAM isnt the only part that needs to be addressed - some of these addresses need to be used for the PCIe bus, for example. You can get round this on some OS's using PAE, but this doesnt work on 32bit windows due to the design of the OS.
