Hi all,

Couple of quick q’s:

1) I have a TR1 - does anyone know what the maximum RAM is on my machine?

2) Does anyone know which RAM chip I need to buy (model no.) that is compatible for the TR1?

3) Can anyone recommend a cheap and reliable place to but RAM online for the TR1?

Thanks all

1. 1GB is official maximum stated by Sony. The reality is that 2GB is possible on the TR since that’s what the 855 chipset supports. You’re best off with 1GB maxed out since 2 x 1GB modules is very expensive.

2. The official Sony part model is: PCGA-MM512U. There are two 184-pin microDIMM slots on the bottom of the system that can take PC2100 or PC2700 DDR microDIMMs. Ideally, you really want a matching pair of memory modules (i.e. two PC2100s or two PC2700s with same timings).

3. Kingston has it although if you shop around you can probably find it for a little bit less.

Groove, is there any performance advantage to having 2gb? I was not even aware that was possible.  Do u have any part numbers for the 1gb sticks that work in the TR?

I have 1gb and drain that down alot when working.  I use FreeMem Pro to recycle the mem on the fly, but what a waste of time….

thanks jigs

Generally speaking, no.

It depends on your application or your number of used applications at any given time.  Basically, if your don’t know why you need 2GB then you probably don’t need it.

Swissbit (http://www.swissbit.ch) manufactures and sells memory modules up to 1 GB in size on their website.
I’m using their 1GB MicroDIMM DDR266 PC2100 172 Pin part.

Be aware that if you install more than 1GB hibernation will have issues, due to a bug in windows xp.

Groovyone,

Thanks for your answers - you are the man.

A couple of more follow up q’s:

1) Is there any major difference b/n the PC2100s or PC2700s? i.e. is one better than the other (performance wise)?

2) Are you certain that my TR1A can handle over 1+ GB of RAM? i.e. right now I have 2 x 256MB installed (total 512) - so if I took out 1 x 256MB chip and replaced it with a 1GB chip - that would work without any problems? (e.g. bringing my RAM up to 1.256MB RAM)

3) Can you recommend any 1GB chips?

4) Are there any places that I could sell one of my 256 chips and use the proceeds towards purchasing a 1 GB RAM?

5) (side question) Do you know of any reliable places that sell the extended battery for the TR1? Thanks

Thanks again

Can you provide a specific link for the specific RAM part?

Also, could you explain further what the hibernation issues are exactly? i.e. does hibernation not work at all?

Thanks again

1. There is no performance difference. The system can only operate using 266MHz (aka PC2100) so faster memory won’t help performance at all. However, the PC2700 memory is compatible with the system and can be run at PC2100. That said, you don’t want to mix PC2100 and PC2700 modules.

2. You “could” but again, you may run into timing issues. You’re probably better off selling both 256MB modules and buying two 512MB modules for a total of 1GB (least expensive option) or simply buying a single 1GB module.

3. The only one i know selling 1GB modules is Swissbit. If you’re in the US, the only place i Know that sells them is PortableOne and they’re $299 each.

4. eBay or this forum.

My advice:

Unless you have a specific reason why you need more than 1GB of memory, I would stick with 1GB in a 2 x 512MB configuration. It’s the cheapest option and will probably only cost you around $130-160. A single 1GB module is $299. Two is almost $600.

Also, as someone posted earlier. Having any memory configuration above 1GB basically disables Windows XP’s ability to hibernate correctly. You can still standby but Hibernation is no longer an option. This is a known issue at Microsoft and they have no intention of fixing it. Windows Vista should fix this problem.

I see… well if I understand correctly then, there is no performance difference b/n the 2100 vs. 2700 - just don’t mix them, correct?

Also, is there a step-by-step guide somewhere on this site or a link which can walk me through replacing these chips?

Thanks again

gr00vy has a nice pic here of the right and wrong ways to do it.

Thanhks dude…

Groovyone is the man… again.

i know when 1gb + would be helpful   adobe photoshop. adobe premiere. or if you want soo many more windows openned in your tiny 10.4 inch monitor

The more memory have you dont use makes ur computer actually run slower so like groovy said if u dont know how u need 2G dont go for it

Just an FYI

$250 shipped… still pricey though.

51.50.

The ones we need are 172pin, you probably found 184pin SODIMMs… but your link item isn’t found… so I dunno.
