Upgrading RAM I have a emachine t5026 that is 512mb and i bought a 1gb memory to install in it. i tried to install it but the computer will not load windows what would cause this issue?

Try swapping the memory in the two slots. It sounds like either one of the memory chips is bad or one of the memory slots is bad.
If you find that one of the slots is bad, then you might try just putting a 1GB Chip in the slot that works.

I don't know your specific model, but some of the Emachines had some memory directly on the motherboard. With the 1Gb and 512Mb sticks installed, boot the machine and report how much memory the system sees. Perhaps the onboard memory is causing you to exceed the 2Gb limit.

Please post the memory size you get here with the above sticks.

Thanks,
Dan

Will it boot with only ONE of the 2GB memory-sticks installed?
Will it boot with ONE of the 2GB memory-sticks AND one of the 1GB memory-sticks?

Look closely at the 1GB memory-sticks.
Does the label show 'DDR266' or 'DDR333' or 'DDR400' or 'PC2100' or 'PC2700' or 'PC3200' ?
Do the 2GB memory-sticks have _identical_ information?
It's definitely _not_ acceptable to have "slower" RAM (smaller numbers) in the new RAM,
but it _might_ be acceptable to have "faster" RAM (larger numbers).

PC3200 is backwards compatible with PC2700. Meaning you can install PC3200 into your motherboard but it won't run any faster than would PC2700, however it will not cause any harm and should work fine.

Emachine's would say you need PC2700 most likely because they're trying to sell you some.

One of your new memory modules or the memory slots on your computer may be defective. I recommend installing a single stick of memory and booting your system. If it is successful then shut it down, disconnect the power and install another stick. Boot again and keep doing so and by process of elimination identify the bad memory stick or the bad memory slot.

This is the "likely" cause and isn't too uncommon.

Good luck.

Do you get any error beeps when you turn on your computer? Check this list here: http://www.5starsupport.com/info/beep_codes.htm

Also, there are three different types of RAM: DDR1, DDR2 and DDR3. I have never come across a computer that will run two different types simultaneously, if your motherboard supports both DDR2 and DDR3 (The pins and key are different, so they won't fit in a non supported slot)

If both sticks of RAM are exactly the same, try running it in dual channel mode, by inserting the RAM sticks in the same coloured slots on motherboard, providing your motherboard supports this

try each ram one by one. if there is prob in ram it will show only 512 instead of 1 GB.. Second check for memory shared in bios

The Ram specifications for your model are:
1024MB DDR2 (2 × 512MB), 533MHz (PC4200)
Expandable to 2GB

If you are using Microsoft Windows, the operating system will recognize the memory by itself, there is nothing you have to do. Go to your start menu, right-click on "My Computer" and choose "Properties". In the lower right corner of the "General" tab, you can read the amount of memory available to you.

If you want to know how to put RAM into your computer, have a look at this web page - it's a good video instruction. Make sure not to touch any of the electronic parts on the stick itself - try to hold it on the side.

If your computer does not recognize the newly installed RAM it can have different reasons:

1. The RAM is bad. Nothing you can do but send it back and get it replaced.
2. You got the wrong RAM. Look at Crucial's webpage (link) and compare the specs with what you've got. They are very reliable and the memory I bought from them always worked.
   
3. It is possible that you have to install the RAM in pairs. (eMachine's web page (link) has no download for a manual and does not cover this topic.) It means, that either both memory slots have to be populated or even populated with the same kind of sticks (2 x 512MB, 2 x 1GB).

Solution: try to replace one of your old sticks with the new 1GB stick and see if that increases your memory. If that doesn't work, take both of the old sticks out and put the new 1GB stick in the slot closest to the CPU (look at the video: it's that unit with the fan on top). If that doesn't work either, try the other slot.
Last resort would be to contact eMachine. You can either use LiveChat or call them. The contact info is on their web page.

If all fails, come back here and leave a comment including what you did. I will check back and then we go from there.

Good luck!

try removing the cmos battery and put it again and booting up.. since you have bought same kind of ram i dont think it could be a problem.also check for the jumpers in *********** board where you can reset your bios. be sure to read *********** boards manual before this

I think you are mixing ram.... Use the same make and module for your ram... when you mix ram, the problem is other ram can be difernt Voltage. some 1.9V, 1.8V, 2.0V, 2.2V to operate. If you have 1.8V and 2.0V the computer won't boot. Hope this helps.

the ram should not go higher then the MHZ or GHz you have

like 2 Ghz computer should not go over 2gig of ram

i hope this helps out
