I would try one stick at a time in one of BOTH OF the slots to see if they are damaged or dirty. A tiny piece of lint or "micro" paper between the metal contacts could mean the difference of turning on or not. You did not say if the the memory sticks are the same speed.That causes problems! Take the stick out and REplace it in again.

    to 2gig .
    Did you buy the menory in a wholesale, or discount store.The reason why they are discounted is that the co does not test the chip to its fullest. Sometimes u get a wacko chip.

Your motherboard my only recognise two of the same size or make of ram. try the 1024mb in on it's own and see if the bios allows the system to boot and recognise it. see what windows recognises, go to my computer, right click, properties and in the main window it will tell you processor speed and look to see how much ram is showing

I upgraded my gategay gt-5428 computer memory 1 gb to 2 gb but still runs with i gb, what i did wrong?
Hello Erik,

Are you absolutely certain that the new module is compatible with your system? Go into the BIOS and see if it is recognized there.

Crucial shows that your computer takes DDR2 memory with support for DDR2 PC2-5300, DDR2 PC2-6400 speeds.

Make sure it is not ECC memory. ECC is not compatible.

If you are sure of the compatibility, I would try to install the old one by itself first and make sure the system boots. Then I would remove the old one and install the new one by itself. Try booting. If it doesn't work, you may have gotten a bad module. (It happens.)

Just FYI, here is the crucial link for your computer:

I have a L7VMM2 - Rev 2 motherboard with a Athlon 2400 processor. I have replaced the 2 x 256 Mb ram chips (PC2100) with 2 x 1Gb PC2700 chips. Total memory is reported as 1Gb (i.e. 2 x 512). I am (almost)...
Have you checked the posibility of 512 Mb limit per slot for your motherboard? This is often at some older mobos. The manufacture page for your mobo is here check the revision you own.

Problems with 3 brand new PC 133 512 MB RAM in Netvista 6794
That last RAM probably is good. Many motherboards have problems using many different memory. All of the memory you have should be at least identical to ensure that they work. When RAM run at different speed or require a little more voltage, they will not let your motherboard boot. You can try mixing up the order you put the RAM in. Try putting the last RAM in the first slot by itself, the motherboard should boot. Then try the rest.

Also, whenever you add or change hardwares, you should clear the CMOS/BIOS settings.

Upgrading ram on laptop, new ram not recognized.
remove the bios battery for a few seconds...and place it back on ...this will make it see the new ram memory modules...if you are sure they are compatible ..they will work .....in fact ..the ddr1 333 512 M is more that compatible with your system and it will work after you remove the battery ...\ my recommendation is to reinstall a clean operation system after you boot up ...and format the C partition too...this have to be done after memory changes to get the max out of them ..

Toshiba Satellite Pro M15-S405 Memory upgrade problem
This usually happens when the laptop is not able to take more then a certain amount of memory, as the system BIOS does not support higher. By saying ACPI as the blue screen, that tells me that the power subsystem does not 'like' having more then 512MB of RAM. I am 95% sure this is your BIOS because of that information. Check and see if you can find a BIOS upgrade for your computer model, and that might fix the issue, if an update is available.

I bought from Gateway to double my ram ( 512 to 1024 ) and now my ram has gone back to 512. How can I find out which chips or whatever they are called have gone dead, the original or the newer Gateway?
Turn the power off. Swap out the memory cards putting one bank of memory in at a time. If the computer doesn't boot up after the swap, chances are that is the bad memory card.

Sdram capacity
its that 512 mb total capacity for your computer memory?? if so read this:
To find the total amount of RAM that can be added , subtract the amount of RAM currently in the computer from the maximum amount of memory the computer can hold. For example, a computer has 256 MB of RAM. If the maximum amount of memory the computer can hold is 512 MB, then 256 MB is the amount of RAM that can be added. this info from the HP website , to find out more , go to http://www.hp.com/support , enter the model number , and look for more information about your computer specs, hope this helps , please rate & thanks AJ
