Full Version: Physically adding RAM ?

I have a problem I need to add some RAM to my archaic HP computer . It only came with 48mb of Memory not including all the other little sound card mbs and such and I need more .

So I have decided my new skill to learn this month is computer component intsallation . Unfortunately I don't know what I am doing .. Well I do, in theory I have a good understanding but I've never done it before .

Is there any-one who can give me a bit more advice before I pull my Modem to
pieces?

I can try to help you. I build my own computers and do all my own upgrades.

I am just not sure how long it takes to drive to New Zealand from the Seattle area... tongue.gif
Kismit
Lol Fluffy unless your running some wicked hydro car thingy you wont make it ..

But you may be able to help me any way . with an upright Modem where would you find the memory cards positioned zand what are the pitfalls if you put the wrong card in , and should I remove the old card before putting in the new one or will they run alongside eachother compatibly ?
PsychicPenguin
wait a sec.. are you talking about a computer (PC?) or a modem?? huh.gif
Kismit
Well I may be confused but , isn't the Modem the wee square box which holds all your hardware like memory ? It was when I was a kid and it looks very similar only it dosen't have a little apple on the front .
Fluffybunny
The modem is the thingy that connects to your phone line, which is what allows you to post here tongue.gif

If you know what type of computer you have, I can find a tutorial to walk you through the installation, with pictures and everything...

Do you already have the memory?

What kind of computer do you have?


Are you sure there isn't a bridge from Seattle to New Zealand? If not maybe a good running start may do the trick.


Here is a basic walkthrough that I found at computermemoryupgrade.net: It may not be appropriate for your type of computer, but I am going to make a guess:

Installing Computer Memory
Memory installation is a pretty easy upgrade to perform. Most of the work, if you could call it that, comes before you actually do the upgrade - in being sure you get the right kind of memory for your system.

SIMMs (EDO)

First some info, though. Your computer, if it uses 30-pin or 72-pin SIMMs, organizes its SIMM sockets into groups called banks. Some boards say that two sockets make a bank.

Some say that one is a bank. Nevertheless, a bank must be full. A half full bank will drive your computer nuts. Also, you can't mix two different kinds of memory in a single bank. For example, you can't put a 4MB SIMM and an 8MB SIMM in one bank and expect to get 12 MB of RAM. Also, many systems require you to put the memory in in pairs. Therefore, if you want 32 megs of RAM, you have to stick 2 16's in instead of one 32.


Here's a shortcut which is almost always true. An older computer with a 386 or an early 486 chip usually has a 4 socket bank of 30-pin SIMM modules. A later model 486 requires only one socket of 72-pin modules. Pentium machines have two socket banks of 72 pin modules, meaning you must install RAM in pairs. In all of these systems, the bank must be full for your system to operate. Following these guidelines, lets say you want to add 16 meg of RAM to your Pentium machine. You could buy one 16MB SIMM, but this won't work because you will have a partially filled bank. You must buy two 8MB SIMMS instead, and install them in a pair.

Turn off the computer, unplug it, and take off the case cover.

Locate the memory slots.

Remove the old memory (if applicable). This will entail loosening the little retainer springs on each end of the memory socket until the memory stick can be removed.

Install the RAM. To do this, first locate the little notch on the pin-side of the module. This notch will line up with a notch on the memory socket itself, to ensure proper alignment. Position the module over the slot at a 45-degree angle with the module pins in the slot. Gently rotate the SIMM until it is in an upright position. When it is in an upright position, the retainer springs will snap into place and secure the SIMM.

Repeat previous step for all remaining SIMMs you wish to install.

Test it. Before you put your case back on, power on your system and make sure it correctly tallies the RAM.

Close up the case.

DIMMs (SDRAM, DDR-DRAM)

Now, we can all thank God that SDRAM and DDR came out, or we'd all have to decipher all that bank stuff in order to upgrade memory. DIMMs are much simpler. Most motherboards have the 168-pin slots for SDRAM or 184-pin slots for DDR-DRAM. Each DIMM slot is a bank, so one can install these types of memory in any combination they want. It is best, if you have several open DIMM slots, to use the lowest number slots first. The slots are numbered, such as DIMM 0, DIMM 1, and DIMM 2. Choose the lesser, unused number. If this is the only module in the system, use DIMM 0. Some older motherboards have both SIMM and DIMM slots. On these, each DIMM slot is a bank, just like normal. The SIMM slots right next to them are usually paired in a bank, just like the normal Pentium bank setup.

Turn off the computer, unplug it, and take off the case cover.

Locate the memory slots.

Remove the old memory (if applicable). This will entail pressing down on the little ejector clips on each end of the memory socket until the memory stick pops out of the socket. Then you just life it out.

Install the RAM. To do this, first locate the little notches on the pin-side of the module. These notches (usually two) will line up with keys on the memory socket itself, to ensure proper alignment. With the ejector clips in the open position, position the module over the slot and begin pressing the module down into the slot. You will need to press down pretty hard. As you press down, the module will sink into place and the ejector clips will close themselves to lock the module into place.

Repeat previous step for all remaining DIMMs you wish to install.
6. Test it. Before you put your case back on, power on your system and make sure it correctly tallies the RAM.

Close up the case.

Lol Fluffy and Phsychic Penguin . I've had my mother in-law staying so I may not be completely comprehensible for a day or two .


You so rock Fluffy allthough thats not the tutorial I need so perhaps if I give you some stats .

Hewlett packard Pavillion 4413 and using SDRAM need anything else ?
Did I tell you you rock . I'm going to build a trans-pacific bridge in you honor ... thumbsup.gif

I got a few specs that may help out: HP Website specs

It looks like you can get up to 256 megs in that little badboy of yours(2 128 meg dimms). Dimms are pretty inexpensive to get a hold of, if you need some help there I can recommend a few sites. I found them at about 45.00usd for each 128 meg memory dimm

Here is another link to a website that has another tutorial for SD ram:Link

Putting RAM is the easiest thing you can do upgrading a computer. Just put in the right one with your computer and your computer should automatically detect theres a new ram in it.

It seems your computer is quite old you could buy a new one tongue.gif
