Still a problem

You Gateway only supports up to 8 GB. memory. Hence it will not see your 5 GB. dimms

tops: 8129 MB (8 GB.). 4- 2GB. Adding the maximum amount of memory will improve performance and help extend the useful life of your system as you run increasingly demanding software applications in the future.

Specs:

Installed: 1024 MB DDR2 (PC4200), 533 MHz memory (two 512 MB modules)

Expandable to: 8 GB (4 memory slots)

How much memory your Windows OS will recognize depends on which version of Windows you are running. 32-bit versions of Windows will see (and utilize) only 3GB or 3.5GB. To utilize more memory, install a 64-bit version of your OS. More information about OS memory maximums can be found at http://www.crucial.com/kb/answer.aspx?qid=4251.

First you need to check your owner's manual or online at the Gateway site to find out how much memory your computer can hold and what type.
Then you need to see how many memory slots you have. You can then go out and buy the memory you need and remove the old and put in the new.
You may just be able to add memory if there are empty slots--otherwise, you'll have to remove the old smaller memory sticks and replace them with larger ones.

Hi there i will help you to get this problem fix: first i must tell you that its only a memory problem its not that the memory is bad, it mean that the computer is not recognizing the memory you put in and this can happen if the memory is not fit correctly into the slot, so you should double check to make sure the memory is fit properly in the slot if you still experience the problem then you should ask someone with more ideas to put it in for you , if the problem still exist take the memory back to the store along with the original 1 and let them exchange it for you with similar to those you take out and if the problem still exist there might be a problem with the memory slot
thanks for asking
if my advise is helpful to this problem kindly vote for me

Hi,

this is telling you that the Dimms ( Memory Sticks ) Have to be the same or equivalent.
i.e:- 2 x 256mb. 2 x 512mb. Your system does,nt seem to like 1 stick of 128mb And 1 stick of 256mb. et,c.
each channel has to have the same amount of memory. put the same memory in slots 1 and 2 on the motherboard, or if there are 4 slots. put the same memory modules in slots 1-2 3 and 4.
If this does,nt work, use the same memory in slots 1 and 3. or 2 and 4 respectively.

The computer has two memory expansion slots—Slot A and
Slot B. You can install one or two memory modules.

1 Shut down your computer completely using the Shut Down
command.

2 Unplug the computer.
CAUTION: Installing a memory module with the computer’s
power on may damage the computer, the module, or both.

3 Close the display panel and remove any cables you may have
connected.

4 Turn the computer upside down.

5 Locate and remove the screws that hold the cover plate in
place, then remove the cover from the bay.

CAUTION: Static electricity can damage the memory module.
Before you handle the module, touch a grounded metal
surface to discharge any static electricity you may have built
up.

To avoid damaging the memory module, be careful not to
touch its pin connector on the side you insert into the
computer.

6 Remove the new memory module from its antistatic
packaging.

7 Insert the memory module in the slot and gently press it down
into place.

The clips on either side of the module will click to secure the
module.

8 Replace the cover plate and the screws.

9 Turn the computer over and restart it.

When you turn on the computer, it automatically recognizes
the additional memory.

Removing a memory module
If you need to remove a memory module:

1 Complete steps 1–6 in “Installing a memory module” to shut
down the computer and open the memory module cover.
2 Pull the clips away from the memory module.
The memory module pops partially out of the slot.

Adding memory
Pulling the clips away from the memory module
3 Carefully remove the module from the slot.
4 Replace the cover plate and screws.
5 Turn the computer over and restart it.

DDR RAM needs to be installed in pairs, as in if you have two 1GB sticks these would, in a four slot board, be inserted in slots 1 and 3 or 2 and 4. The other odd 512MB stick could go in any other slot theoretically speaking. But, you would be better off leaving it out. The SPD chips on the two 1GB sticks should match themselves to time at the slowest common or fastest common denominator.

There is a chance that by having the odd bank population that you said worked for awhile installed as you had, that the MB RAM slots were put under unusual voltage stess. There is a pretty good chance you can remove the 512MB stick, leave the two 1GB sticks in slots 1 and 3 or 2 and 4. But, this is VERY important: consult your board manual or access it online and read what the population requirments are for the slots as in some cases, the two matched sticks go in 1 and 2 or 3 and 4. This little oddity is found from time to time.

Consult your manual or download it and read how the slots need to be populated and stick with the two 1GB sticks.

There are memory testing programs you can find for free at majorgeeks dot com and test your RAM once you have it populated correctly.

In the future, I'd suggest you purchase RAM from Kingston or Corsair directly online as they usually offer a lifetime warranty and this RAM right now for you board is dirt cheap.

Hope this FIXED, as in ANSWERED you question and was more than helpful. Should you feel compelled to rate this solution after reading, either rate it FIXED or not at all. I know its helpful by default, that's what we do here. But only a thorough answer can FIX your situation. You should be fine if you follow my instructions. But, please consult you manual.

have to tried to run both sticks in the slot thats working 1 at a time to check theres not a problem with the ram itself, try moving the 1 thats working now into the other slot and see if it works, then try the other stick of ram

put the new ram in slots 2 and 4.

Slots 1 & 2 are channel 1 slots 3 & 4 are channel 2, you need matching sets in each channel to run dual channel mode.

almost anything is possible, but in general a 430 watt P/S should be able to run 2 gigs of ram, however that doesn't mean that the ram you purchased is the correct ram for the motherboard or that you have so many other added perpherials i.e. dual or tripe CD drives, hard drives, USB perpherials that the load is simply to great for your P/S. A rule of thumb is find out what your system ' will ' run with and then work from there. For example if a person was serous about this problem he might disconnect all power connectors to all other equipment other then his hard drive, monitor/video card, and his motherboard just to see if the system could then boot normally. If it did, chances are the memory is okay for the motherboard in normal circumstances. However if the system did not boot normally, it might be an incompatibility with the 2 gigs of memory on that particular motherboard. Memory is not a generic add-on. A person needs to make sure the memory is correct for a motherboard before installing. Also you indicate the present P/S is only 4 months old, any particular reason why you had it changed out to begin with??

I had exactly the same problem with a 2 year old LX-1. The card worked fine on the computer, formated no problem but would not work in the camera.
I took a can of air and used maybe 3 one second bursts to blow out the card slot. Card immediately started working.
