Upgrade RAM I need to upgrade as I have Oem512MB DDR 333MHZ (PC2700) memory Arua 03120005. How hig can I go? Can I insert 3 of 1GIG PC3200?

need more info.What memory did you use?
That MB requires either DDR PC2700 or DDR PC3200 Unbuffered,NON-ECC memory.
Max of 1gib per slot.

wrong parts, its not support by chipset
Memory -
One of the following
2-GB DDR Synch Dram PC3200 (400-MHz) Non ECC (2x 1GB)
Memory Speed Supported DDR Synch DRAM PC3200 (400MHz) non-ECC
Product documentation

Ram Memory typically operates at half of the frequency rate, ('Speed'), that the Processor's -> FSB does.

Your motherboard supports Processors that have either a 400MegaHertz Front Side Bus, (400MHz FSB), or 533MHz FSB, or 800MHz FSB.

(Northwood Core for 400MHz FSB. The rest is in the other solution I provided)

Processor has a 400MHz FSB?
You can use DDR Sdram ram memory that is 266MHz.
(PC2100)

Processor has a 533MHz FSB?
You can use DDR Sdram ram memory that is either 266MHz, Or 333MHz.
(PC2100 and PC2700 respectively)

Processor has an 800MHz FSB?
You can use DDR Sdram that is either 266MHz, or 333Mhz, or 400Mhz.
(PC2100, PC2700, and PC3200, respectively)

NOTE*
When using a processor that has an 800MHz FSB, and using PC2700, (DDR at 333MHz), the PC2700 ram memory will run at ->
320MHz.

JEDEC has set the voltage requirements for DDR Sdram at 2.5 Volts.
'Performance' ram memory that is DDR Sdram may use higher voltages.
Not recommended unless you know how to overclock.

Although the motherboard, and the ram memory module may have SPD, it doesn't always work,

http://en.wikipedia.org/wiki/Serial_presence_detect

A lot of times you are faced with going into BIOS Setup, and changing the ram memory voltage, IF BIOS Setup has this feature.
This is why I say overclocking experience helps tremendously.

You want Low Density, Unbuffered, Non-ECC, and a CL of 2.5 for PC2700, and a CL of 3.0, (3) for PC3200.

[Why would anyone want to run PC2100> Lol! ]

You need DDR SDRAM like this,

Best value for the money

Have a nice day!

• Your Packard Bell Easy Note maximum RAM capacity: 2GB
• The Easy Note W3910 has 2 memory slots or sockets
• This Easy Note module upgrade PIN count is: 200-PIN
• The memory speed is: DDR 333MHz, PC2700
• The motherboard NON ECC DIMM type for your Easy Note W3910 is: SODIMM.

so your looking for 2x 1GB ddr 333mhz pc2700 memory chips.

:)

This is the memory specs for the SR1500.
Presario SR1500NX Memory Specifications Standard Memory 256 MB (removable) Maximum Memory 2 GB Memory Expansion 2 sockets Memory Comments PC2700 DDR SDRAM DIMMs. CPU Type 2.0GHz AMD Sempron 3000+ Model Comments 333MHz FSB, VIA KM400A Chipset.

The PC2700 refers to the RAM speed, so you can use PC3200 which is faster RAM than PC2700, the PC3200 RAM should be more expensive not cheaper unless this supplier has stock he needs to unload.
You will not get any speed performance with the PC3200 RAM because the motherboard cannot make use of this faster RAM.

You should be able to use just 1 stick of 1GB. your model supports
Each memory slot can hold DDR PC2700,DDR PC3200 with a maximum of 1GB per slot.*

Hi,

According to the maintenance manual only 266Mhz Ram can be added to the notebook.
This would be SDRAM.
Hope this helps!!

Kind regards!!!

Hi reisrui, yes it is odd. (It's not the first time I have seen this.)
According to you're manual on page 6, under Specifications. The manual say's you can run up to a Max speed of PC3200 400MHz, 1GB in slot one. In slot 2 you can run a Max of 1GB of PC2700 333MHz in slot 2. Every motherboard I have come across that can run two different speeds of memory. The system will reduce the Max speed to the lower MHz memory speed. If you currently are using 512MB PC3200 400MHz in slot 1 & add 1GB of PC3200 400MHz into slot 2 for a total of 1.5GB of memory. The motherboard will ruduce the total memory over all speed to PC2700 333MHz. Motherboards alway run at the lower memory speed if two different speeds are presant.
I can’t be 100% sure of the 1GB of PC3200 400MHz into slot 2, will run at all! Or if it will be reduce down to 333MHz. I am sure you can run 2GB of PC2700 333MHz, 1GB of memory per slot in you're board for a total of 2GB.

If I can help you further, feel free to post.
Suggestions & comments welcomed.

you can upgrade to a max of 2gb on that board. These are your 1gb options: 1GB PC2700 333MHz DDR Memory, 1GB PC2100 266MHz DDR Memory, and 1GB PC3200 400MHz Non-ECC Unbuffered 184-pin DDR DIMM Memory. Install a set of any of these and your off and running.
