Rst, KNOW THE NUMBER OF REFRESH CYCLES YOUR MOTHERBOARD SUPPLIES! This is dependant on the chip set on you motherboard and the chip set initialization code in you BIOS. (Theoretically, depending on the limitations of your motherboard chip set hardware, the BIOS initialization code could be changed to use a higher refresh number allowing all available DIMMs to work together. I have never done this so, it is just a theory.)

Second, ASK THE VENDOR (OR MANUFACTURER) HOW MANY REFRESH CYCLES ARE REQUIRED FOR THE DIMMs YOU ARE CONSIDERING PURCHASING! This will tell you immediately if the memory will work in your system or not. There is no magic about it. Ask if the memory requires 1k, 2k, 4k, 8k, or 16k memory refresh cycles.

If the number of refresh cycles required by the DIMM is the same or less than the number that your motherboard supplies, the memory will work just fine. If it is more than your motherboard supplies, you will only "see" part of the memory on the DIMM. Additionally, any other DIMMs in the system may not be recognized at all. No Good!!!

1GB PC400 RAM does not work with motherboard A7S266-VM/U2


Hello the home page is here:

http://support.asus.com/download.aspx?SLanguage=en&p=1&s=10&m=A7S266-VM%2fU2&os=&hashedid=n%2fa

If any drivers or manual needed select first your windows.
Click on global for download.
Unzip the file and you need a pdf reader (adobe) to read the content.

Here are some specification about you mainboard:

2 x DDR DIMM Sockets
Max.2GB unbuffered PC2100/PC1600 non-ECC SDRAM Memory
2 x SDR DIMM Sockets
Max.2GB unbuffered PC133/PC100 non-ECC SDRAM Memory


(Note: DDR ram and SD ram memory can not be used on A7S266-VM/U2 simultaneously)

This means you can`t use SD RAM together with DDR ram.

The bios could have a setting for this because of the use of 2 different ram types.

Try downloading the manual.

Good luck

Hello, I want to know, if the motherboard Asrock K7VT2 can support DDR2 memory.


No, it supports DDR, SDRAM...front side bus speed 266/200 MHz...you can max out with 2GB's of PC3200...1GB in each slot. I hope this helps.

What is memory card EliteGroup P4VMM2 V8.1 Motherboard


You will need to install either DDR RAM (DDR 200 or DDR 226) or SDRAM (PC133 or PC100) memory. You cannot install both, you need to choose. The motherboard supports a maximum 2GB and there are two DDR and two PCI slots so 1GB +1GB would be the assumed maximum.

More details on your Motherboard here: http://www.motherboard.cz/mb/ecs/P4VMM2%20V1X.htm

RAM Slot does not recognize more than 512MB ( 184 )


Consider updating your motherboard bios.

http://www.asrock.com/mb/download.asp?Model=K7VT2&o=BIOS

Also make sure that your memory is correct for this system:


- Max. capacity of system memory: 2GB DDR or 2GB SDRAM
- DDR x 2, DDR266/200 non-ECC, un-buffered memory
- SDRAM x 2, PC133/100 non-ECC, un-buffered memory

Ram compatabilty for k7s5a motherboardand can I run a 1gig of ram with this board


A really unique MB since Each DIMM slot can accommodate DIMMs up to 512 MB in size, although both DDR and SD-RAM are supported, but any one at time, i.e. one among consisting of a bank of 2 DIMM slots(blue pair & black pair having the pairs 2 slots each) for DDR or 2 DIMM slots for DDR or SDR memory cannot be used at the same time. Thus the board supports either 1 GB of PC133 SDRAM, or 1 GB of DDR sdRAM, but not both at the same time.

I hope you got the Catch 22 here !! Nice low costs for doing simple work?
but it's a Catch 22 situation{either choose the Devil or Hell !) ................. sodeep

Can i install 1GB ddr2 on P4VMM2 Motherboard? i want to upgrade my pc; board is: can i P4VMM2 Motherboard; cani i use 1GB ddr2 on this and a 512 MB if vid.card? -jayvee_yao@yahoo.com


Hi,

Unfortunetly you cannot use ddr2 memory on this motherboard. The motherboard supports only PC2100/PC1600 DDR memory if you have version 8.1 of the motherboard. If you have v5.0 of the motherboard than you can only use sdram or ddr 266Mhz RAM. The same goes for the video card. The p4vmm2 motherboard is a rather old motherboard so I don't think it will payoff to upgrade the computer. It will be probably the best if you buy another computer.

best regards

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!
Mike

Ram support for intel 845 motherboard


Ok. So you've defined the Intel 845 chipset on your motherboard.

But is it the 845 or 845G chipset?

Click HERE for the specifications of the Intel 845 chipset.

Click HERE for the specifications of the Intel 845G chipset.

Peepnklown is only HALF right.

The Intel 845 chipset does NOT support PC133 memory.

The Intel 845G chipset DOES support both DDR and PC133 memory.

The difference?

The 845 has a single memory controller for DDR memory.

The 845G has two memory controllers. One for DDR and one for PC133.

Although you're going to need DDR memory as it is FASTER and less expensive than the older PC133 memory. (Believe it or not.)

I do NOT recommend using Corsair's ValuSelect memory on this chipset. I have two boards with the 845G chipset and that type of memory does not allow the board to boot.

These boards typically come with DDR266 (PC2100) modules installed.

I would go ahead and buy DDR333 (PC2700) memory for it. The board you have may not utilize the full speed of that memory, but will use tighter memory timings if the RAM is clocked down by the board. This will result in better efficiency of memory use by the processor.

Think of it as giving the motherboard "breathing room".

I could recommend PNY memory for the most basic compatability. (Not that they manufacture their own RAM modules...) Or perhaps Nanya, Infineon or Microtek.

Look for memory compatability lists for your particular motherboard module online. You could also use PNY's memory configurator on their website.

Click HERE for PNY's memory configurator.

Good luck.
