Intel 855PM Chipset vs 333-DDR Memory support???
First of all, apology if this question is posted on the wrong 'topic' area.
I recently bought an ACER 804LCi with following specs: Centrino 1.7, 855PM Chipset.
The system comes with 512 MB (266-DDR) memory on a single bank. My questions are as follow:
1. Does the chipset support PC2700 (333 DDR) if I want to install one? (I have looked through the intel website, the 855PM product description webpage says it *does* support 333 DDR memory. But when I searched the net further, there was this white paper regarding the chipset, with no mention of 333 DDR, only supports for 266 and 200 DDR.)
2. If it turns out that I can install 333 DDR, can I mix and match? i.e. a 512(333 DDR) bank + 512(266 DDR) bank?
Hope someone can help me out, please. Thank you guys.
Regards.

Thanks for feedback surki1,
Just had a browse through the net again today, and it's turned out that the chipset supports DDR-SDRAM...am not sure whether this is right?
...but still cant find the answere to if 855PM chipset actually supports 333...
Nevertheless, when I looked into a website of one of the acer notebooks online retailer, to check what kind of memory options are they selling for the acer notebooks, they didnt seem to make any distinction regarding which memory options (i.e. 333/266) will fit into which of the acer notebooks(which some are running on 855GM or 855PM or even AMD based system). I could only conlcude that if I buy the 333, it should work well with my notebook. But again, I dont want to splash out a lot of money only later to find out it doesnt work, and worst, most most retailers wont accept memory package which has been opened.
Any advice? Anyone?

Thank you Callandor and Chris.
I am aware that faster memory, i.e. PC2700 will run at the fastest bus speed supported, i.e. 266, if fitted on such board.
I am trying to establish if it's any worth buying PC2700 (am planning to buy 2x512 MB PC2700) to replace my 2x256 PC2100. There is
1. Significant price different betwen PC2700 and PC2100 here in London, UK.
2. I thought it woud be nicer to get a faster DDR, and *actually* works at 333Mhz with my chipset.
But thank you for the feedbacks.

1. Rang acer, they didnt know anything, all they say. it's *possible, but we cant guarantee* so, that is as good as *dont know*
2. Am giving up
3. Thanks for feedbacks guys

If you have a local vendor who will take returns, you can buy the faster and slower parts, and benchmark them in your system, and take back the slower or more expensive part.
If I were you, I'd buy the PC2100 if it's cheaper.

As far as i know the DDR works like this
The empty slot shoud have the same equal size of memory i.e u have 266 the other slot should have the same size 266 if you can purcahase two 333 and replace it with 266 it will work...
But in case of SD RAM there can be mis match but DDR unfortunately it has to have a matching memory size.
