Dual-channel memory support requires matching memory modules (identical) to be installed in pairs (2 at a time). The color-coded slots are for A & B memory banks.
Your MB (this is an OEM board, not retail) can use DDR 333/400 speed memory, so purchasing memory "kits" would be ideal.
If you plan on using more than 2 sticks of memory, note that the RAM will then run at 333 mHz, so purchase the lower-cost 333 modules. 32-bit systems will not address 4 GB (the maximum you can install). The OS will use the RAM, just not indicate it is installed.
Ideally, you would want to buy a 1GB memory kit (2- 512MB modules) minimum for Windows XP, or a 2GB kit (2- 1GB modules) for Windows Vista. You would install these two sticks of memory into slots of the same color. If you are installing less than 4 sticks of memory, choose the color closest to the processor to install them in first.

    Sasram, you are correct. buy 2 new 1 GB sticks of 400 if you can, you appreciate the boost in speed-- 2 GB is not a lot of RAM anymore, your system will enjoy it. Be sure to defrag and run diskcheck once in a while, or get a good utility like TuneUp.

Your instruction manual for the mother board should have this, however, with dual-channel motherboards, you will want to fill the same colored slots together if you have dual-channel capable memory, otherwise you'll want to fill in the off-colored slots first.  ASUS has it's manuals online, so if you've lost yours you should be able to download a pdf of it from their website.

I have an old K8V-MX mother board. Recently, the 1G RAM spoiled. I try to replace it by 2 x DDR400 512M RAM. Both 512M are used and with the same part no Kingstone KVR400X64C3A/512, but different...

Click on this link. It will open a copy of the motherboard manual. Check section 1-7 on system memory. Verify the part numbers of you RAM against those listed. SOme will only work in one slot or the the other but not both. Older boards were strange that way, in the early days of dual-channel memory mode.

Hope this helps!

How much can you upgrade memory (RAM) in a asus p4vp-mx motherboard. There are 2 slots with 256K each (128 pin, I think)

The Asus P4VP_MX has two slots for DDR2 SDRAM and supports a maximum 2G of memory, 1G per slot.

I am using this ASUS (asus M2N-MX nvidia mcp61p chipset

According to the manufacturer's web-site:

this motherboard has 4 x DIMM sockets,
supporting a maximum of 4 GB
of DDR2 800/667/533/ Non-ECC, Un-buffered Memory

and supports Dual Channel memory architecture.

So, add one 512MB DDR2 533 Mhz RAM into one of the slots,
being sure to leave *ONE* *EMPTY* slot between the two sticks,
in order to enable the high-performance "dual-channel" option.

Try your computer -- it should feel faster.

If you still think that need more RAM, buy two 512MB (or two 1024MB) DDR2 533 Mhz RAM, putting the 2 sticks into the two empty slots.

Ddr ram sdr ram i am same time input that tw0 thats not show two ram capacities just show one ram'' asus p4s533 model please help me

Hi safran0785,
The Asus motherboard, P4S533-MX can run two different types of memory.
(Just not at the same time & in different slots).
You can use 2, 184-pin memory, PC2700/PC2100 MHz or PC1600 up to 2GB. (1GB DIMMs) inserted in the two memory slots closest to the CPU.
Or you can run SDR memory, 168-pin PC133 or PC100MHz DIMMs up to 1GB of memory in the last two slots farthest from the CPU.
You can not run both types of memory at the same time.

The 184-pin DDR PC2700MHz memory is much faster then SDR memory.
The maximum amount of system memory supported is 2GB.

Need more information/questions, just post here.
Good luck safran0785!
