Question about Shuttle Computers & Internet

1 Answer

Memory I have an older computer and some time back I had to have a new motherboard and several other Items installed in it. I decided I wanted to upgrade the memory. I found a site and run the scan to tell what kind of memory I would need. So I found out it would take 3-256 MB PC100 DImm 168 Pin. which would be a total of 768. My problem is when we installed them it only recognizes 2 of the memory cards, which is 512 total memory. We Have installed them One at a time to see which one it is not recognizing and the third slot seems to be the one. Is there something else I can do to see why this is happening? the Mother board is a Shuttle AI61. Thanks

Ok well there could be a few things going on here. It is possible that A: your third stick is damaged which I'm assuming you dismissed through your installation of one at a time, B: the third dimm slot is damaged and is unusable, C: the dimm slot is turned off in your bios. 

Now looking at the Shuttle A161 motherboard it would appear you have a primary dimm slot and then expansion dimm slots (technically these are called the controller dimm slot and the estensions) 

The controller slot which is offeset from the other two should have your largest ram, make sure the ram you stick in this slot isn't a stick that requires dual recognition. Some ram is designed to work in a pair even in the early PC100 class ram. Most PC100 ram you'll find now requires the sticks to work in pairs and the ram is coded for this. (Especially since PC100 is on its way out very fast.) The expansion slots can be fitted with a pair that will work together. I doubt that your third and primary slot is turned off as it is the controller slot. If none of your ram works in this slot replace the old ram in to this slot and just use the two expansion slots. It may not be as much ram as you want but the motherboard has presets that are just problematic. 

My general advice however is, that if you're running this motherboard which is fairly out of date, I'd upgrade to a new computer. Buying a cheap Dell desktop or even a barebones off of and transfering your current Harddrive and what not over would probably be easier for you and will carry you for the next five years or so.

My computer has one long beep 2 short beeps, I put in new RAM and still does the same.

One, if I may; clean the gold plated contact pins with a pencil eraser, use air to remove the eraser dust. THEN try again before buying new Ram Memory.

(You are Following Anti-Static Precautions, right?)

Unplug the computer from power. Press the Power On button in, and hold for a count of 10 seconds. Let go.
Do this procedure two more times.

Plug the computer back into power.

What this does is clear CMOS Error Codes, and resets BIOS Setup back to the factory default settings.
We are just trying to clear CMOS Error Codes.

WAIT 1 minute, turn the computer on.

Still no?
'Slap' BIOS around a little bit.
Hold the Power On button in for a count of 10 seconds, or until computer turns off.
WAIT 1 minute, turn the computer back on.

I had to do this 3 times, one time, in order to get BIOS to recognize the new Ram Memory.

A) Ram Memory HAS to be in Slot 1. (DIMM 1)
That is the ram memory slot the Processor reads first.

Don't care about the other Ram Memory modules at the minute.
Just want to make sure a module is in Slot 1.

B) Are you SURE you have the correct Ram Memory?
There is a TOTAL amount for the motherboard, and EACH ram memory slot has a Maximum amount also.

Install in Slot 1 first. Try computer. If it works, then install ram memory in other ram memory slots.

No didn't work?
Then install in Slot 2.

You may find one of the ram memory slots is bad.

My motherbaord has only two slots for DDR2 RAM.Both slots are filled With 1GB DDR2 Ram Each.I want to increase RAM memory . Without Removing previous Ram from their slots.How to Solve the above problem.

Buy a new computer with more than 2 Gigs of RAM installed. Problem solved.

Otherwise I guess I simply don't understand why you would not want to remove the 2 smaller RAM modules and just replace them with larger capacity ones.

If you do decide to upgrade the memory, then one good and easy way to find out for sure how much RAM your computer can hold is to go to WWW.CRUCIAL.COM and run their SCAN MY COMPUTER feature.

This handy utility will scan your hardware configuration and tell you exactly how much RAM you currently have installed and what type it is.

It will also tell you how many RAM slots are fitted on your motherboard and what the maximum memory capacity is for each slot and the total capacity for that motherboard.

If your computer does have room to add more RAM, it will provide you with specific recommendations as to exactly what type and size of RAM stick to get to maximize the memory capacity and performance of your computer.

I hope that was helpful to you, good luck.

I have a gateway MA3 MX6453 that will not boot if both memory chips are installed. It starts up, fan runs briefly then shuts down, all panel lights stay on...but nothing else. Found that it doesn't...

Sounds like you're definitely having an issue there, hardware-wise, but the question is whether you have a bad RAM chip or bad motherboard. Since you say the same chips have worked fine for a while then you've answered some of my questions.

What made you suspect this in the first place? RAM Error?

If you can, find someone with the same memory and try your chips in their machine, or see if you can try theirs in your machine. That way you can identify whether it's the motherboard or the RAM for sure.

If you don't have access to that, you might see if you can take the RAM (remember they're static-sensitive so see if you have one of the anti-static bags around so you don't 'zap'em in the meantime) to somewhere like Best Buy so they can slip them into a machine to see if either doesn't work.

Seeing as how either works when you put 'em in, but just not both, I would be inclined to think the problem is on the motherboard. On a handfull of motherboards, there's a setting for how much memory/how many banks to use, so if someone wanted to mess with you they could turn off one bank (jumper), but that's a lot less likely.

Check your BIOS and the memory settings there. You might reset that to "default" just in case something got changed.. electronics can be fickle. since it's "several years" old as you state, it may very well be time to shop around and see if another motherboard, or another computer would be a better investment of time and funds.

Remember, you'll need to match the RAM to the motherboard requrements, so if you decide to replace the mboard pay attention to what kind of controllers you have now (IDE perhaps) versus what kind of controllers the mboards today have. There are many on the market, so pay close attention to the details.

(mine is 5 years old and I'm backing up my essential for when (not if) it finally gives up the ghost)

Good Luck!

Have older model presario computer plug usb plug in the back but nothing came up it said new hard ware found when i click on it computer could not found the things to set up so do i need the instalation...

An installation disk may help considerably.

Word of warning though. You say its an older model. My concern is that it may have usb 1,0. That is fine if you only have usb 1.0 items to connect to it and some items that are 2.0 may still work.
Point is that not all usb 2.0 will work on usb 1.0

You really need to work out what you have and decide if you may need to an a usb 2.0 card to get you up to date.

There is no way to convert usb 1.0 ports to 2.0.

Also being an older computer you need to be aware that if you are on an older operating system this too may restrict you from making best use of new usb hardware.

Windows 95 / 98 are best upgraded to a newer version of windows but that does not always mean vista.

Desert Combat will not start

With pleasure! Your problem is that during the time you did not use your game, you have added more items and your hard disk is getting overwritten. What you need to do is to look at the size of your game and figure how much memory you need. Your only choice is that you look at all your programs and decide which ones you can spare erasing. If you are a little handy, you cna go to the local used computer parts and buy a hard disk of at least 160 GB. All computers have provision for a second hard disk. Turn off your computer and then pull the line cord. Make sure that the "new" drive is set at "slave" and then install it connecting all connections with care. When you turn your computer on, at the start, on the upper left corner, it will identify the "new" drive and name it "D:\" most of the time, or choose another letter. Then you will have two drives with sufficient memory. Install whatever you want. Caution: during the installation of any program, the manufacturer, being used to microsoft, will ask you if you want the program installed to "C:\xxx". You need to tell the computer to change from C:\ (this is known as C-Drive) to the "new" Letter Drive, chosen by your computer. If the computer gives funny performance, change BOTH DRIVES to "Cable Select". Good Luck! Thank you for your consideration and choice to our service! CONSTANTIN (arzconst)

Abit AW8 LGA775 Maximum memory

Hi there
Sounds like the bios will need updating as the board will support 8BG ram.
Put your old memory back in the machine, boot into windows, go to the motherboards manufacturers website and download the latest bios update and install it and reboot.
make sure you read the info on how to install the bios update.
I must also warn you that if you are using a 32bit operating system it will only recognize 2.9BG of memory, there is nothing you can do about this apart from install a 64bit operating system if the board supports 64bit processors.

Good luck and thanks for using Fixya!!!

No, you've got it in one.

I think you'd only have two memory slots anyway.. so shut down, unplug the power, then remove the existing memory. Push the white tabs that are on either end of the memory out and down until the memory pops loose. Remove it, then install the new memory the same way around.

I'm not sure if your motherboard can support 2gb of RAM, but in any case, that is the correct procedure for upgrading memory.

How much memory can i add?


I have upgraded several computers using this site:

If this link doesn't work, just google for "Crucial"

They have an online scanner that will check your installed RAM, it will even try to identify your motherboard. It will then tell you how many available slots there are and give several different upgrade combinations.
There is a small active x facility to download which allows your computer to be scanned. The site is surfer friendly, no harmful activity and perfectly safe. Perhaps give it a go.
