Hi, I don't know if I should get single or double sided ram for this mother board, and is low density ram ok? Thanks, Wayne

Disks come in different formats . Double density. Single density Double sided singles sided. You must purchase the disk that your machine calls for.

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

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.

you need to check with board to fine what ram works with first.i use what they say to use so no problems later and save money as well ok jim

Check the specs for your new ram. It sounds like you have double density ram installed. If your motherboard only supports single density it will only see 1/2 of the modual hence 64meg showing for 128 stick.


Please rate this solution if it has helped you.
Thanks, Gary

Here you go....
CPU Support

• Socket 939
• Support AMD Sempron, Athlon 64 and Athlon 64FX processors.
• Support 800 and 1000Mhz HyperTransport (HT) interface speeds.

System Memory

• Four 184-pin DDR SDRAM DIMM sockets.
• Serial Presence Detect
• Support for single-sided or double-sided DIMMs (DDR 333 / DDR400)
• Support for up to 4 GB system memory
• Asynchronous HyperTransport and memory controller interface speeds
• Supports dynamic link width and frequency change
• Non-ECC RAM (ECC memory will run in non-ECC mode)
• Single and dual channel mode operation:
  • Single channel mode with single DIMM, non-symmetrical population or non-identical DIMMs
  • Dual channel mode with 2 or 4 identical DIMMs, populated symmetrically

Good luck!

Look at the sticks of RAM -- "high" density means fewer chips on each side of the stick, i.e., newer technology and production methods have packed more bits into each chip, while "low" density usually means 8 chips/side, using older RAM chips.

Older motherboards do not expect to find "high" density RAM, and typically will only detect 1/4 or 1/2 of the RAM on the stick.

If you buy a new motherboard, it will support BOTH densities.

I had similar problem with CORSAIR XMS2 2GB (2 x 1GB) 240-Pin DDR2 SDRAM DDR2 800 (PC2 6400) Dual Channel Kit Desktop Memory

If this is your RAM:
Corsair 1024MB Value Select PC2-4200 (533MHz) DDR2 RAM, 128Mx64non-ECC, 240-pin DIMM, Unbuffered, CL4, Lifetime warranty (VS1GB533D2) Then it is high density. You need low density to work, look for one ending with an 8, not 64.

Go to Crucial.com and install their configuration utility through your browser. They will tell you what you have and all the combinations you can do to max out your system. Look at the specs of the RAM and you can get it from Crucial or some other vendor.

If you are referring to the ASROCK mobo then it will work on the high density although not as good as with the low density but it will nontheless work.

Solution:



i)  LOW DENSITY modules have 100% compatiility with ALL systems and ALL chipsets.
    HIGH DENSITY modules only have 10% compatibility

    here compatablity means LOW DENSITY RAM are accepted by all system(100%)  or any make           system.. HIGH DENSITY RAM are accepted by 10% by only some system or computers...


ii) in order to check system performance or amount of Computer RAM usage press the ctrl+alt+del
   simultaneously a new window(window task manager) will appear showing:

    CPU usage: showing the amount of CPU or processor utilized at that particular time.
    PF usage: showing the amount of RAM memory utilized at that particular time.
    Physical Memory: showing Total RAM Memory, Available Ram memory....

iii) baiscally they are two types of RAM they are:

    DDR1:which is older one supported by older system  or older mother boards which is costlier
    DDR2: which is latest one supported by all new system or new mother boards which is less                         costlier

    DDR: double data rated ram......which will send data at a double rate compared to SD RAM

iii) here color doesnt matter, these slots either support DDR1 or DDR2 but not both at a time
    
    DDR1 has 184 pins or gold plated pinssss... on the edge of the RAM
    DDR2 has 240 pins 

    so difference doesnot allow DDR2 to placed in DDR1 motherboards or vice versa...

iv) it does have anything to do with no of chips on the RAM but they only differ whether it is DDR1 OR DDR 2(DDR2 are much faster than DDR1)

NOTE: whatever may the the RAM, each RAM has FSB(called Frequency...) which determines the frequency of rate at which data is tranferred from RAM to processor(CPU)  usually in MHZ such as FSB 300, 400, 200 , 333...................

more the FSB the faster data is transferred to the processor(CPU)

dont worry even RAM with less FSB's work well with the processor....having 1 GB RAM or 2 GB RAM is engouh, it only matters with the speed of CPU ... but not RAM......
