System reguirements to inrease ram memory


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! ]

I have this ASUS P4GE-MX Motherboard. I want to upgrade my ram from DDR 256 MB TO DDR 1 GB. For temporary purpose, I tried another 256 DDR ram with 400 MHZ, but I had some problem with booting my system....


Hello, The Motherboard's specifications mention that it uses DDR Ram, while the FSB runs at 400MHz. That means that any kind of DDR memory will work up to the maximum of 2 GB (it has 2 slots, so it's up to the max of 2x1GB DDR sticks).
There's no issue with the speed, actually the faster you can get the better results you will have. Try looking for 1GB DDR 400MHz (preferably two of them, if you want to max out the capacity and since it's kind of cheap to do so).
The one you tried and didn't work, might be due to a faulty RAM module.

Pc3200 wont see it


I pulled up the specs on this board and the maximum memory speed for this board is PC2700 (333). PC3200 is (400). It is most likely out of range for the motherboard to use. I would try doing a bios update on the board with the old memory installed before returning the memory.

Upgrading ram


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.

Memory 1 gb with pc 3200,can i use in p4se?


Dear blatz

The ASUS P4SE - motherboard Supports DDR SDRAM RAM.

The Supported RAM Speed is: PC2100, PC1600, PC2700


This means that the speed is at a maximum 333Mhz. The PC3200 is rated at 400Mhz but its ok. It is backward compatible with PC2700 or 333Mhz.



It will simply work but not at its maximum speed.

RAM upgrate


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.

Memory upgrade


you can use any DDR 180pin. But having two RAM of different speeds may not be compatible sometimes, so upgrade it to 1Gb by just using (1) 1Gb pc3200.
