In is refernce from the type S forum

I did some research and looked into it for the TR and it turns out. It is also possible.  The Intel 855GM in the TR3 can handle up 2GB RAM at 333 mhz.

not that I use the gig I already have, but good to know.  Cheers

Can anyone else confirm this too ? Could this mean an absolute jump in performance or are there going to be any downsides.

You won’t get any jump in performance unless you’re working on tasks that require more than 1GB of memory. You may be able to speed up a few operations using a large RAM DISK swap disk but again, the gains will only show up in a few situations.

So upgrading RAM to 2 gb wouldnt speed up the windows loading process ? I noticed a significant change in starting up speeds when i upgraded my old toshiba to 512 MB a few years back.

No, it won’t.

Basically the way this works is that Windows tells all programs they can have as much memory as possible. As things load and allocate more and more memory, if you don’t have much physical RAM, Windows is going to put stuff that isn’t being used on the hard drive and will retrieve it when it’s needed again. The hard drive is many times slower than RAM so it will slow your system down while it’s moving allocated memory to and from the hard drive. At 256MB, space is tight to fit Windows AND the programs you want in memory. 512 will give a lot more breathing room so Windows doesn’t have to page to disk. Unless you have a ridiculous amount of programs launching at startup, this is about the last point you should see a benefit in startup times. 1GB is good for power users and 2GB is more than most non-pro users will see benefits with at this point.

sigh.

That’s not how modern operating systems work.

It will give you a performance boost, because the kernel automagically uses larger read-ahead values, allocates *every* free page to things like disk cache.

Using a ramdisk is actually *contraproductive*, because you take away some pages which could be used for caching and buffering from the kernel.

On Linux and other Unixes, there is a thing called “temporary filesystem” or “shared memory filesystem”, which is basically a ramdisk without that downside, on Windows no such thing exists. Just plain old ramdisks, which just use up the physical amount of memory.

And using the ramdisk for swap is actually one very, very senseless thing to do. The kernel often decides to put things into swap - although more than enough memory is still available, or “free” (although, in today’s operating systems vm implementations, no thing like “free memory” really exists). Why? To speed things up! Some things are just not needed in memory so it’s better to swap them out on disk and leave more physical RAM available to the cache/buffer mechanisms.

VM is a very, very, very, unbelievably highly complex thing today. You will notice a big memory increase. It’s possible however that you won’t notice a lot when you’re upgrading from 1GB to 2GB but the performance increase is still there.

On the windows XP platform, what would be some of the noticable differences with an increase from 1GB to 2GB?  I sure there would be some improvement with graphics processing, but would it improve gaming performance, video editing, and similar programs?  Plus, the fact that it would be jumping from a PC2100 to a PC2700 memory module.

I am curious to know some more details. 
Since the TR3 is my only computer at this time.  I use it for everything.

Here is the manufacturers web page with specs:

I have written to swissbit regarding this RAM upgrade and if they have some test results they can provide us with just to realize how big the change is. Some person at a link provided here claimed that swissbit had test results for the S type upgraded to 2 GB, may be they have it for the TRs too

It should take 3-4 days.  Good luck.
I would like to see what the test results are.  I didn’t think about asking about them when i emailed Swissbit.

Heres the response that I recieved from Swissbit today.

Hello,

the desired module is a standard µDIMM DDR 333MHz memory module. Standard means it is conform to the JEDEC standard that defines the pin out and the physical sizes for the connector. So it will definitly fit into the connector. We tested a Sony VAIO S1 in our laboratory and it fits in easily. The S1 is from a similar generation as the TR3 and it was able to run even 2GB having both slots equipped with our 1GB µDIMM DDR module. Find below a drawing with all the important values, if you like you can verify it on your own.

I hope this information will help you. Hopefully the module will get the best out of your notebook. Enjoy it.
Regards,

Andreas König.

Yes, graphics processing is harddisk intensive, so it’s a candidate.

but would it improve gaming performance,

No, I don’t think so

video editing,

Oh yes!

and similar programs?

All in all you get less harddisk accesses.

Of course this doesn’t happen right after turning your notebook on. The caches and read-ahead buffers have still to be filled.

But after 5-10 minutes, it’s safe to assume that the most relevant filesystem metadata is loaded into memory. At 2GB, after half a day of working on the machine, you can really expect to have everything relevant in memory. Harddisk accesses will be reduced to a bare minimum where very seldomly used data is loaded (i.e., you open up a movie that you haven’t open up for the past 2 hours) and where you don’t care about your harddisk accesses anyway.

Plus, the fact that it would be jumping from a PC2100 to a PC2700 memory module.

If the chipset handles it gracely, than that’s a performance increase no matter what. Right after turning it on, no matter what you do. The CPU’s main task is to fiddle around with bits in your memory. If your memory’s faster, your computer is faster.

I am curious to know some more details. 
Since the TR3 is my only computer at this time.  I use it for everything.

Then go for it!

2gb… wow.  i’d run sooo many programs just to take advantage of that

even 1gb is quite a bit

Thanks, FrodoID for the explanation.  It helped out a lot.

Unfortunately i found out that the PC2700 doesn’t work with the TR notebook.  The TR is made to run on DDR266 or DDR200 due to the 855GM not being able to utilize the DDR333.  A 855GME is what is needed for that.  To bad the TR doesn’t come with 855GME, but the S does.

That is the only downside, becuase they do offer a PC2100 1GB module to run with the TR series.  Which will be placed on sale shortly at the Swissbit website.

I just got a reply from the swissbit tech team, there is no mention of the test results i requested but anyway..

Hello Varun,

I checked the technical specifications of the TR5MP and well, it takes a maximum
of 2 modules with 1GB capacity. So if you like you could even reach the 2GB in
your notebook as well. The only thing to know is, the TR5MP is equipped with the
Intel 855GM chipset and can run therefore only PC2100 DDR modules, which is
266MHz. So please order SDM12864A1B42MT-75 which is in fact a PC2100 DDR module
for µDIMM-Connector of Sony VAIO portable series.
Enjoy the product and good performance,
Andreas König.

The real question: how much would it cost?
