Re: Add more memory to my computer

Not able to access it in what way? Is there a password for the BIOS or something? Normally on most (all?) Compaq models, F10 is the key to use to access the BIOS.

Will an Asus A8M2N-LA motherboard accept a DDR400-PC3200 in addition to what is already installed?

Yes, that Locating Notch is there for a reason. Keeps people from putting the wrong ram memory in.

Uses DDR2 Sdram that is either 533MegaHertz, or 667MHz.
That is PC2-4200, and PC2-5300 respectively.

{PC2-4200 is sometimes known as PC2-4300 also.
It's up to the ram memory manufacturer }

DDR2 Sdram has 240 gold plated contact pins. 120 on each side.
DDR Sdram has 184 contact pins. (Gold plated also) 92 on each side.

Each contact pin has a purpose. It is either a pin for power, or ground, or signal.

The above is an example of DDR Sdram ram memory.
(This particular example is DDR Sdram that operates at a frequency rate of 266 Million Cycles per Second, or also can be said as 266Megahertz)

The Maximum Total Amount of ram memory for the motherboard, is 4GB.
The Maximum Total Amount for EACH ram memory slot is 1GB.

IF, you have only ONE ram memory module, ('Stick'), it goes in Slot 1.
On the motherboard it may have DIMM 1 next to it.

It is the ram memory slot that is closest to the Processor.
A Processor ALWAYS reads ram memory Slot 1, First.

At the bottom of a ram memory module are contact pins.
Gold plated.
Everywhere else on the ram memory module is the BODY.

Handle a ram memory module by the Body, because the Body is coated with a see-through protective plastic.

Refrain from touching the gold plated contact pins.

On the sides of the ram memory module, are blackish rectangular objects.
These are DRAM chips.

With the recent disasters in countries that produce DRAM chips, the prices of ram memory have gone way up.

Presario sr1710nx what type memory has an excellent wizard for locating memory.
Computer memory upgrades for HP Compaq Presario SR1710NX Desktop PC...

Lists memory compatible with your machine.
Memory Type: DDR PC3200, DDR (non-ECC)
Maximum Memory: 4GB
Slots: 4icon_note.gif Although the memory can be installed one module at a time, the best performance comes from using matched pairs of modules.

I have also found that the memory occasionally is not recognized. To fix remove the ram and clean electrical contacts with a clean pencil eraser. (Rub the contacts to clean.) Then replace memory. (My machine failed to boot, cleaning the contacts fixed the problem.

The board for this appears to have a dead ram slot.If putting ram into second slot the monitor just goes black with line distortions.Remove the Ram and install to first slot everything works ok add a 2nd...

Inspect the memory slot carefully. If there are are bent pins in the slot , you can probably align them with a pointed tip. Otherwise the best option would to replace the motherboard. Because after the process RAM is the fastest component in the computer. Out of experience in repairing the motherboards ,i recommend to replace the motherboard.

Thanks Fixya

Continual "beep" on startup. Startup screen appears and computer freezes. Replaced hard drive but not the problem. Could it be the memory board?

The beep you hear is a BIOS Beep Code.

The computer's way of telling you something is wrong, and a general area to look in.

The Compaq Presario S5100NX uses an Asus P4G533 motherboard, with an Award BIOS,

Left-click on - Motherboard Specifications, P4G533 (Echo)

One long continuous beep indicates Ram Memory failure.

Your diagnosis is correct.

I would like you to take the ram memory module/s out, and clean the gold plated contact pins on the bottom.

Suggestion is to try this, before resolving to replace the ram memory.
A pencil eraser is used to clean the contact pins.

The Compaq Presario S5100NX, uses DDR Sdram ram memory modules,

The above link is provided to give a closeup side view, of a DDR Sdram ram memory module, and it's gold plated contact pins.

Use the pencil eraser to stroke down each contact pin. Both sides.
(A DDR Sdram ram memory module has 184 contact pins. 92 on each side)

Refrain from touching the contact pins with your fingers.
You can touch the body of the module anywhere you wish, as it is coated with a see-through protective plastic.

If an eraser on the end of a pencil is used, do Not let the metal part of the pencil, rub against the contact pin.

Use air to remove the eraser dust. You can use a can of compressed air for computers, or air from your mouth may be sufficient.

Reinstall the ram memory module/s.

HP Support product specifications, indicate the Compaq Presario S5100NX comes with one - 256MB DDR Sdram ram memory module.

If there has been two ram memory modules installed, suggestion is to reinstall one at a time, to see if there is a bad ram memory module.

Yes, it's kind of a pain.

When installing just one ram memory module, it is installed in Slot 1.
The ram memory slot that is closest to the Processor.

Scroll down the above page until you come to the motherboard illustration, and the motherboard photo underneath it.

In the motherboard illustration - DDR DIMM 1 (64/72 bit, 184-pin module) indicates Slot 1.

Install one cleaned ram memory module in Slot 1, plug the computer into power, WAIT 1 minute, turn the computer on.


Computer shut down normally (Start>Turn Off Computer>Turn Off), unplug from power, observe anti-Static precautions.

Remove that ram memory module, install the other one.

[Anti-Static Precautions:

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.
(Hmmm, I did everything right, but my computer doesn't work)

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

If you get up, and walk away in the middle of working on your computer, upon your return Touch the metal frame again ]

Note the Locating Notch, on the bottom of the ram memory module.
It lines up with a Locating Lug, in the bottom of the ram slot on the motherboard.

At a casual glance the Locating Notch may seem to be in the middle.
It is Not.
Assure that you have the module turned the correct way when reinstalling, so that the Notch lines up with the Lug.

Note the Locks at each end of the ram slot. (White in color)
The top of the Lock is eased towards the outside.
(Away from the ram slot)
Ease both Locks up at the same time.

Note that the bottom corners of the ram module, sit in small slots, of each Lock.

As the ram module is pushed down into place, the Locks are brought up simultaneously.

Note that there is a Notch, on each side of the ram module.
The Lock has a protrusion ('Bump') that fits into the Notch, when the ram is fully seated in the ram slot.

Sometimes the 'Bump' does not fit in perfectly into the Notch. It's okay.

If there are two clicks, from the Locks snapping into the Notches, the ram memory module should be fully seated.

ATI AGP card and Compaq Presario S3100NX with open AGP Slot

This particular model of the system is basic home use system not built for games.
You can put in either a PCI graphics card or an AGP 4x graphics card that should not take more than 1.5v of power.
The max you can put is 128 MB , you can try the 256 MB, but i would suggest against it .

Thanks for using fIxya

You have One AGP 8X slot ,so add the same specification card.
For resetting the password of bios
  1. Temporarily set jumper CLR_CMOS to pins 1-2. c00783713.jpg
  2. Wait 5-10 seconds and then return the jumper to pins 2-3. c00783714.jpg When you start the system you will need to enter BIOS setup to reset any custom BIOS settings.

Presario won't recognize second 256 RAM

Remove the original module, install just the new one and then start your computer. If it doesn't start, the memory you bought is bad. The system boards used in the Compaqs will auto-detect memory, and there are no jumpers or BIOS settings needed.

Ram issue with compaq presario 5000 G1 Series

as you can see from the information below there are different requirements for RAM to work stable in your system . Most importand are the RAM VOLTAGE , SPEED , and Configuration of chips. you will need to consult the manual for qualified RAM requirements. Some RAM will work but not very stable. make sure the voltage supplied by your system is enough for the RAM. If you are running DDR RAM in dual channel mode, the ram needs to be the same size also. DIMM modules for the HP computer must meet the following requirements
  • The number of pins on the DIMM must match the socket type.
  • DDR memory requires a 184-pin slot and 1.8 operating voltage.
  • DDR2 memory is not compatible with DDR1 memory and requires a 240-pin slot and 2.5 operating voltage.
  • Synchronous dynamic random access memory (SDRAM): Only use DDR type SDRAM memory if the computer came with DDR-SDRAM.
  • SO-DIMM modules for the HP computer must meet the following requirements
    • The number of pins on the DIMM must match the socket type.
    • SO-DIMM memory requires a 200-pin slot.
    • DDR2 SO-DIMMs are not compatible with DDR1 DIMM and DDR2 DIMM memory modules.
    • With a computer running at a system bus of 533 MHz or 667 MHz, use a PC2-4200 (DDR2 DIMM 533) type.
    • The following requirements must be met for the DDR memory to function in dual channel mode:
      • Same density (256MB, 512MB, etc.)
      • Same DRAM chip technology (x8 or x16)
      • All either single-sided or dual-sided
      • Matched in both Channel A and Channel B memory channels

Adding memory

You shouldn't,t have to go into bios at all. Shut the computer off, install the ram, turn on computer. The bios will see the memory automatically.
