"Put it in and reboot"... be sure the aptop is OFF when you add memory! Otherwise, you can damage BOTH memory and laptop! Once memory is installed there is no "trick" to get it recognized. If it is good and meets the BIOS specs, it will be recognized and registered after a cold boot.

1. Be sure the memory is inserted properly (both clips on the sides are flush with the half-moon tabs between memory and metal clips).

2. Sometimes on a memory slot that has been empty a long time (and gets a bit corroded) it is a good idea to insert the memory, remove it again and reinsert 5 or 6 times (only) to clean the contacts.

3. If number 1 and 2 have been done, and you still have this error, then there is a problem with the memory:

It may be the wrong speed (PC100 instead of PC133, etc)

It may be too LARGE for the BIOS to use (all laptops have maximum memory per slot specs that must be observed, because the laptop cannot see memory that is greater than its specified capacity.

In any case, check the manual or the website for your laptop, to get the specifications for memory type AND capacity per slot, and TOTAL memory if you have two slots -or memory soldered on board).

    Hola, la capacidad total de este modelo M2352 de eMachines y similares es de 1024Mb, NO de 1280Mb, esto es, tiene dos placas de 256Mb originalmente, una interna y una externa, juntas suman 512Mb, eMachines dice que acepta 1GB y en la web dicen que acepta 1GB, nadie define la capacidad completa, todos venden RAM de 512 y de 1GB, solo cambiando la RAM externa, si se cambia la externa por una de 512Mb mas la interna serán 768Mb totales sin problemas de reconocimiento, se puede cambiar la interna y la externa por un par de RAM de 512Mb sumando 1024Mb o 1GB como dicen sin problemas de reconocimiento, es la mejor alternativa que he deducido, por la falta de información y confusión que genera esa misma te pasas de 1024Mb totales, siempre va haber problemas de reconocimiento sin importar la marca o capacidad de la RAM a instalar.

    Sorry,my espanol is insufficient. But my Latin makes me think I understand, so I'll try:

    Some older BIOS 2-slot .laptops/desktops have quirky restrictions on mixing RAM sizes in the two slots. For example, when adding a 1024 and a 256 together, the smaller one may need to be in slot 2 (or "bank 2" as it is sometimes labeled) or vice-versa. Other BIOS may see the first bank (if it was 256) and only address RAM of 256mb after that, 12mb, meaning it would only recognize 512mb, not 1280. So beside cleaning the contacts on the RAM, you should try rearranging the order, IOW, which RAM is in the first slot, which is in the second. Of course, you must check your manual to see if it lists total/maximum RAM capacity, as you may be trying to exceed that restriction. Last, just because two different RAM chips work OK by themselves, does not necessarily mean they can work "together". If they are different speeds, many older BIOS machines will not recognize the second RAM chip..

My GA-VM800PMC motherboard has 1GB and 512Mb of Ram installed but does not recognize all of it. ?? (thanks in advance)

Just put in one memory card in the first slot and see if recognised. Then try the other in the same slot . If both ok then try the second slot and see if that too recognises both ram sticks. If the sencond does not recognise either stick then the slot is at fault.

Hi there,I understand your issue and would be glad to help you..
Soloution 1:Make sure that your Video card is firmly fitted into your AGP slot and that if you have a DVI slot(And if both your monitor and system handle DVI)try using that rather than DVI..

Soloution 2:It could be possible that your video card is not campatible with your current motherboard,out of intrest,What motherboard have you got?

When I take pics w/ my kodak easy share c813. The pics don't go to the memory card, it goes directly onto the camera's hard drive. how do I fix this problem?

Sounds like it doesn't recognise the card.

Probably the first thing to try is formatting the card. There is a function in the camera menus to do this. If it won't format or gives an error when you try, then there may be an issue with the connectors in the card slot or the card may be incompatible.

Maybe it is having trouble with the size of the memory. Memory cards have grown enormously in capacity in the last couple of years, and even relatively new cameras may not be able to cope with the memory size of the newest cards.

SD and SDHC cards fit the same slots, but many cameras won't work with the SDHC (high capacity) cards. SDHC is not backwards compatible.

When I plug in my compactflash memory card into the slot thing on my tower nothing happens. how do I get it to work?

You probably have multiple slots. and some memory cards will fit into other slots. usually the card type is listed under each slot. make sure you have it in the right one first. also there is usually a light that will change colors when it detects a card inserted. then windows should take care of the rest.

Additional SD card memory installed in the card slot

Check to see if it is the proper SD card. while several size ( memory) cards may fit the port the player may only recognise a 2 or 3 gig card.

Genius G-Shot HD55 (camera) - How to get SD card working??

For Genius G-Shot HD55 you need to insert the SDHC card deeper into the slot until it clicks closed, like opening a pen, then when you want to remove it press it again until it clicks to release, like closing a pen. Your card is recognised after the deep click insertion and restarting the camera.

Radeon graphics card and 3rd RAM slot conflict

I thought this board looked familiar to me. I recall some rules for the memory cards. Do all your memory cards meet this requirement:

Supports up to 3GB PC1600/2100/2700/3200* DDR SDRAMs

If you are using DDR 400 you can only use 1 slot.

What kind of memory are you using?
