RAM is a type of computer memory accessed randomly during hard drive processes.

A computer's RAM is considered "random" because any byte of memory can be accessed without processing previous bytes.

Purpose of RAM

RAM is used to load and run programs or applications on a computer's operating system. More RAM means more applications and programs can be run simultaneously.

SRAM

Static Random Access Memory, or SRAM, stores data on a computer in a static method, meaning the data stays the same with power being supplied to the memory chip. SRAM is the faster RAM when compared with DRAM.

DRAM

Dynamic Random Access Memory, or DRAM, is a type of memory used in personal home computers. This type of memory must have an electrical current to refresh. DRAM is used more commonly because it's less expensive to manufacturer and install in chips.

EDO RAM

Extended Data Output, or EDO, is a new type of DRAM chip that uses technology to add 10 to 15 percent more speed than normal. A computer that uses EDO technology must meet the chip requirements or the EDO will not be recognized.

FPM

Fast Page Mode, or FPM, is a RAM speed enhancement that uses rows of bits selected in columns and rows of the memory.

FPM is used in EDO RAM.

You can upgrade it direct x 10. on win xp.

Instructional steps

• RAM

1. Determine what kind of RAM you need, and whether your computer has enough open slots to hold it. The new RAM should match the existing RAM's specifications and configuration.
   
2. Shut down the computer and leave it plugged into the surge suppressor.
   
3. Disconnect all peripheral devices, such as the monitor, from the computer.
   
4. Remove the computer cover.
   
5. Ground yourself to the computer with professional grounding equipment like an anti-static wristband or hold a metal part of the chassis.
   
6. Remove any cards or internal components necessary to give yourself unobstructed access to RAM sockets.
   
7. Pick up your SIMM (single in-line memory module) or DIMM (dual in-line memory module) by the ends without touching pins or chips.
   
8. If adding a SIMM, find the notched end and turn the SIMM so that it is parallel to the existing RAM card(s). Insert the SIMM into the socket at a 30-degree angle. If adding a DIMM, insert the DIMM straight in so that it is perpendicular to the motherboard.
   
9. Use slight pressure to keep a SIMM from backing out while rotating the module to an upright position perpendicular to the motherboard.
   
10. Make sure the small holes on each side of a SIMM fit into holders
    
11. Feel or hear retaining clips lock a SIMM into the socket; close the side clips on a DIMM.
    
12. 1 Gently try to pull the module out to ensure it is locked in position.
    
13. Replace all internal components.
    
14. Leave the cover off and reconnect the monitor, keyboard and mouse.
    
15. Turn on the computer.
    
16. Check the amount of RAM by right-clicking the My Computer icon in Windows and choosing Properties. On a Mac, use the About this Macintosh command in the Apple menu.
    
17. If you don't see the right amount of RAM, turn off the computer and try "reseating" the SIMM or DIMM (take it out and put is back in) and reboot. If that doesn't work, call a technician.
    
18. Shut down the computer and disconnect the peripherals again.
    
19. Replace the cover and reconnect all the peripherals.
    
    

You can calculate it yourself.
a = the number of simm slots
b= the maxium value of ram chip the moher board allows


there for the total is a * b ram memory
eg 2 slots , 512mb max memory chip size = 1024mb memory max

SDRAM (Synchronous DRAM)
Almost all systems used to ship with 3.3 volt, 168-pin SDRAM DIMMs. SDRAM is not an extension of older EDO DRAM but a new type of DRAM altogether. SDRAM started out running at 66 MHz, while older fast page mode DRAM and EDO max out at 50 MHz. SDRAM is able to scale to 133 MHz (PC133) officially, and unofficially up to 180MHz or higher. As processors get faster, new generations of memory such as DDR and RDRAM are required to get proper performance.


DDR (Double Data Rate SDRAM)
DDR basically doubles the rate of data transfer of standard SDRAM by transferring data on the up and down tick of a clock cycle. DDR memory operating at 333MHz actually operates at 166MHz * 2 (aka PC333 / PC2700) or 133MHz*2 (PC266 / PC2100). DDR is a 2.5 volt technology that uses 184 pins in its DIMMs. It is incompatible with SDRAM physically, but uses a similar parallel bus, making it easier to implement than RDRAM, which is a different technology.

Not different types per se, but you may be able to put different speeds.

Type would be like DDR Sdram, or DDR2 Sdram for example.

Speed is a slang term for Frequency Rate. What frequency rate does the ram memory module (Stick) operate at.

Example: DDR2 Sdram that has a frequency rate of 667MHz. (PC2-5300) MHz stands for MegaHertz.

Mega = approximately 1 Million. Hertz stands for Cycles per Second.

The above ram memory module operates at 667 Million Cycles per Second.

If you install two ram modules that have a different frequency rate, all the ram memory installed will operate at the slower frequency rate.

(Provided the computer will support more than just one frequency rate)

Have a computer in mind, or is this just a generic question? A what if?


Reply to your recent comment:

If this is in relation to two different manufactures of your ram memory, it shouldn't be a problem.

Where you may get into trouble in this area, is if one ram memory module (Stick) is generic, or low budget, and one ram memory module is a high performance gamer ram memory.

Without knowing the exact manufacturer of your computer, plus the Model name of it, and also knowing the information you have about your ram memory 'sticks', the following information is just generic, or general information.

High performance ram memory may use a higher voltage. Not always, but a good portion of the time.

High performance ram may also use a faster set of ram timings.
It may also have high density DRAM chips, and the chip configuration may be setup differently.

(The black rectangular modules you see on the side of a ram memory 'stick', are DRAM chips)

To explain so far;

SDR Sdram was the typical ram memory for years after SIMM ram memory.
SDR stands for Single Data rate.
Commonly just referred to as Sdram, but in actuality that is erroneous.

(Sdram stands for Synchronous Dynamic Random Access Memory)

Then came DDR Sdram.
Double Data Rate Sdram.
Then DDR2 SDram.
Double Data Rate 2 Sdram.
Then DDR3 Sdram.
Double Data Rate 3 Sdram.

1) http://en.wikipedia.org/wiki/SDRAM

(Anything you see on a Wikipedia page that is in blue, is a link to more information.

To further illustrate this,

2) http://en.wikipedia.org/wiki/DDR_SDRAM )

SDR Sdram specifications were all over the place. What was considered to be a standard for one manufacturer, differed for another manufacturer.

The JEDEC organization was formed.
JEDEC sets the standards for ram memory from DDR Sdram on up.

Voltage for DDR Sdram is 2.5 volts
DDR2 is 1.8 Volts
DDR3 is 1.5 Volts.

Ram manufacturers found that by upping the voltage requirement on high performance ram, the ram could perform, better.
Not true in all cases, as there is high performance ram that operates at the JEDEC standard.

Ram timings were also varied.
Also the chip configuration
Plus the density of the DRAM chip.

Unless it is a really cheap, generic ram module, (Stick), there will be a manufacturers code on the side.
With this code I can tell you the specifications of that ram module.
I can also explain

No - there is no code for that, the printer should recognize the additional 8MB memory instantly after restart.
Did you follow the manual description on page 4-5 (41-42 in the pdf file)?

1. Install the SIMM into the slot and push gently until it clicks into place.
2. Do not touch the memory chips and the surface of the main controller board. If static electricity collects, it damages the memory.

I would assume that either the SIMM is not connected correctly (it should fit in only one direction and should really "click" in) or the SIMM itself is damaged.

If you have any more questions, just come back here and leave a comment - I'm happy to help.

No there are no DIP switches to change, or jumpers to move on your motherboard, in regards to your BIOS recognizing ram memory installed.
(BIOS. Basic Input/Output System. This tiny program, {64MB in size usually}, that is burned into your BIOS chipset, is what recognizes ram memory on your computer)

Things to know about the older Sdram ram memory.
1.It's really SDR Sdram. Single Data Rate Synchronous Dynamic Random Access Memory.
DDR is Double Data Rate Sdram, DDR2 is Double Data Rate 2 Sdram, and so on.

Point? All ram from SDR to DDR3, IS Sdram.

2.Standards have been set by JEDEC for computer ram memory starting from DDR Sdram on up. This standards were not implemented back in the day of SDR Sdram.

Point? Ram memory manufacturers didn't all follow the same standard, and ram memory made for one computer, would Not work in another computer.
This means you need THE ram memory for YOUR eMachines computer.

Main factors when buying SDR Sdram,
A.Correct type. You know this. SDR Sdram.
168 gold plated contact pins on the bottom of the ram 'stick'. (82 on each side)

B.Correct 'Speed'. ('Speed' is slang for Frequency Rate) You know this. SDR Sdram that operates at a frequency rate of 133MHz. (Or also known as PC133)

C.It must be low density Non-ECC ram memory. It cannot be high density ECC. (Error Control Correcting. Used for Server computers mostly)

D.Correct CAS Latency. Also known as Ram Timings. 3-3-3-3-2 would be normal for SDR Sdram.

E.Correct Chip Configuration. How the DRAM chips are accessed. DRAM chips are the black rectangular chips on each side of your ram memory 'stick'. Also what size the DRAM chips are in MegaBytes. (MB)

F.What the Maximum TOTAL Amount is for the motherboard. Is it 256MB? 512MB? Or more?

G.What the Maximum Amount is for EACH ram 'slot'. (Correct speak for 'Slot' is Bank)

H.Do you have four ram 'slots'? You MUST have a ram stick in Slot 1. This is the slot closest to the processor. It is the first ram slot the processor 'reads'.

Your nick name sounds fimiliar, you need to remove all the memory, power up, power down, put the old memory back in and you should get picture.
