One of the ram isnt recognised???

For a Chaintech 9BIA motherboard;

Motherboard chipset is an Intel 845,

PC133 (SDR Sdram at 133MegaHertz;

{Single Data Rate. The proper term, not just Sdram.
Double Data Rate Sdram is Sdram.
Double Data Rate 2 Sdram is Sdram.
Double Data Rate 3 Sdram is Sdram.
DDR Sdram, DDR2 Sdram, DDR3 Sdram.

Synchronous Dynamic Random Access Memory )

Low-Density, Unbuffered, Non-ECC, Cas Latency of 3

(Don't get some cr@p off of Ebay.
It's usually high-density, ECC, that was used by old server computers)

WHEW! Unless you just want to run 1GB of ram memory, I would toss that board! (Two 512MB sticks) ->

-> Need two 1GB sticks of SDR Sdram at 133MHz

$400 smakeroos USD!!

Bah! That is just cra-zy!

Maximum TOTAL Amount is 2GigaByte. (2GB)
Maximum Amount for EACH ram memory slot is 1GB.

IF, you only have ONE ram memory module ('Stick'), it goes in Slot 1. (DIMM 1)
That is the ram memory slot closest to the processor socket.
The Processor reads ram memory Slot 1 first.

If your computer has two RAM slots on the motherboard, i would recommend trying it. The computer will run on the 512MB stick alone and just not recognise the other stick. And if it works it works.

I have searced for support documentation and came up with none for the original MS-6526

I run my original version MS-6526 on a 512MB PC2300 (DDR1) and a 512MB PC3200 (DDR1) and it runs just fine for games and videos.

Personally I would recommend trying the DDR2 first and if that fails, return the card and get a DDR1 card. They are expensive, but at least they work.

Your machine supports, DDR2 SDRAM or (DDR2) type Ram, maximum 2GB and has two Ram Slots.

Good luck.

Thanks for using FixYa.

From what you have stated, the original ram memory was two sticks of 512MB.
It's PC2-5300
(DDR2 Sdram at 667MegaHertz)

When installing ram memory, and installing two sticks with one stick being larger, the larger stick of ram memory is installed in Slot 1.

This is the ram memory slot that is closest to the Processor.
(The Processor reads Slot 1 first)
On the motherboard it has DIMM 1 printed next to Slot 1.

The 1GB stick should go into Slot 1 (DIMM 1), and the 512MB stick should go into Slot 2 (DIMM 2)

Scroll down for the motherboard illustration, and photo.

Won't boot up with the original ram memory installed again?
1) What type, and size of 1GB ram memory did you install?

2) What ram memory slot did you install it in?

3) Did you follow anti-static precautions BEFORE you put your hands inside your computer, and BEFORE you took that ram memory stick out of it's protective anti-static bag?

[Your body carries Static electricity.
Static will fry out (Short Circuit) the hardware components inside a computer.

You may not even see it, or feel it.
Poof!
No computer.

Computer unplugged from power, computer on a table, computer case open, TOUCH the metal frame to relieve your body of Static.

{A couch, bed, or directly on a carpet floor are HIGH areas of Static]

Before you answer my questions try this;

If the two sticks of 512MB PC2-5300 are still installed, follow anti-static precautions, and remove them.

Take a pencil eraser, and clean the gold plated contact pins on the bottom of each ram module. (Stick)

http://en.wikipedia.org/wiki/File:Generic_DDR_Memory_%28Xytram%29.jpg

(The above example is DDR Sdram, not DDR2 Sdram. I posted the link so that the gold plated contacts are clearly shown.

DDR Sdram has 184 contact pins.
92 on each side.
DDR2 Sdram has 240 contact pins.
120 on each side)

Remove the eraser dust with air. Use a can of compressed air for computers, or air pressure from your mouth.

Reinstall the ram memory modules.

Computer unplugged from power, press the Power On button in.
Hold the button in for a count of Five seconds.
(Count 1001, 1002, 1003, 1004, 1005)

Let go of the Power On button.
Do this procedure two more times.

What you are doing is clearing CMOS Error Codes, and resetting BIOS back to the factory settings.

Plug the computer back into power.
WAIT 1 minute, then turn the computer on.

I await your findings, and answers to my questions.

Is memory matched (DDR2 667)

Have you put original mem in slot 2

Download / install CPU-Z with both modules in and run program to see if it shows.

If all above is correct may be damaged mobo.

This is for your laptop from vendors site.

Memory5
• Configured with 512MB DDR2 SDRAM (1 slot occupied and 1 available)
• 512MB(min)/2048MB (max), 2 memory slots using 256MB, 512MB or 1024MB PC4200 DDR2 533MHz SDRAM.

it sounds to me that you have parallel port memory. This means that you have to have the same, ie both stick being 1gb, or 512mb. I just fixed my aunts pc and she was having the same problem . once I installed both 512 sticks it recognized both. ^_^ hope this helps. good day

Yo u have 2 slots in u r machine I am sending u details information of updradation in ur machine :

frequency of ram should be

667 MHz Dual Channel DDR2 SD RAM
option 1.
A system ready for the next generation of applications and games 3 or 4GB1 Dual Channel2 DDR2 SDRAM
2.
A system capable of handling Windows Vista® Aero as well as today’s latest games. 2GB Dual Channel2 DDR2 SDRAM
3.
Basic performance for the Windows Vista® AeroTM interface (PCs purchased with Windows Vista Home Premium and less than 1GB of memory will NOT be capable of running Aero). 1GB Dual Channel2 DDR2 SDRAM
4.
Basic performance, lowest initial cost (Windows Vista® Home Basic) 512MB Dual Channel2 DDR2 SDRAM

Not compatable at all.
DDR SDRAM memory uses 184 Pin Dimms
Double-Data-Rate Synchronous Dynamic Random Access Memory, better known as DDR SDRAM or DDR RAM for short, is a type of very fast computer memory. DDR RAM is based on the same architecture as SDRAM, but utilizes the clock signal differently to transfer twice the data in the same amount of time.

DDR2 SDRAM uses 240 Pin Dimms.
DDR2 SDRAM improves on DDR SDRAM by using differential signaling and lower voltages to support significant performance advantages over DDR SDRAM.

If your question has to do with buying a video card that is going to use DDR2 ram, that would be a faster graphics card. You can also get video cards with DDR3 ram which again is even faster.
Oddly enough in respect to system memory DDR2 is supposed to be faster than DDR yet the DDR memory cost more than the DDR2. Go figure.

Have a great weekend!

Your board can only handle 2Gb of total memory.
2 x DDR2 SDRAM DIMMs, Dual Channel DDR2 533/667/800.
Check your manual.
