My home computer will not except 512 stick of ram ??

Question

My home computer is running on 256 ram, I went out today and bought 512 of ram (the man double checked it with my 256) My computer will not boot up with the new 512 stick of ram ?? It go'es "beep - beep - beep" Can anybody in the world help on this subject

Answer 1

the beep,s you are hearing is a sign that your memory is eitherincompatible or not inserted correctly
first check is make sure the white clips on either side of the ram are correctly closed and holding the memory ok,if needed take out the memory and re-insert it again
however i have bought a 256mb sd ram module a few years ago and although it was exactly the right module it did exactly the same as whats happening to you
i just took it back to the shop and they happily exchanged it,as some modules although they seem the same are not compatible with your motherboard or p.c model
i have allways bought kingston value memory as i find no problems with this make ,and i also beleive corsair are very good too
try swapping memory banks(slots) and see if this makes a differencebut i would recommend you return it to the shop you bought it,im sure they will exchange it
note: some memory needs to be installed as "pairs of 512" so you need to check this aswell
also make sure the memory you have has a speed(this is the pc3200 ect code) which is the same or higher(as memory is backward compatible)
however if the 512mb module is slower than your existing module this will cause the system to fail to boot
this is why some pc enthusiasts buy memory faster than their stated spped as the newer faster memory is cheaper than the older types,this may seem strange but the older memory gets the more scarce they become and harder to find
for example if you were looking for a 16mb edo so-dimm for a ibm thinkpad,this can cost around £5 per megabyte as these are very rare,but i look at computer shows and boot sales for old p.c,s just so i can either revive them or salvage some parts such as old memory so i can sell them to other enthusiasts
take the memory back to the shop tommorow,but just to be sure go to crucial(http://www.crucial.com/) and run the on-line memory tool and this will give you a report with your memorys exact specifications,print this out and take this to the shop,the guys at the shop will know exactly what you need,when they exchange it ask if they can give you kingston memory,you cant go wrong with that
any more help just let me know
good luck

Answer 2

There are three possibilities.

1) The 512 stick is bad (or the guy was wrong, and it isn't the same kind of ram)

2) You stuck it in the wrong slot - try it in the other slots in case there is one that is for using a standalone stick (it should be the same one you pulled the 256 out of.

3) Your motherboard won't recognize the new stick due to it being the wrong kind of memory, wrong speed, or too large.

Try sticking the 256 back in, if it won't come back on, you might've messed something else up while inside the computer (easier than it sounds).

Answer 3

Your slot where you put your new stick could be not working.
If your computer is old maybe your mother board only can handle so much of RAM.
Try taking out your old ram stick and replacing your new one in there, and see what happens. Thats where i would start.

Answer 4

the beeps mean the ram won't work. if you system is old, it may not take a full 512 in one slot, or the memory you were given is EEC registered. this type is for servers and very very few systems. if your board is supposed to take a 512mb in a slot then you'll need non-eec and unbuffered.

Answer 5

Well putting the ram in can be a little funny, try putting both ram sticks in and then switching them around and trying again. Your computer should boot.

Answer 6

your mb may not be able to run more than 256 or 378 check your man on ram limit.

Answer 7

Some computers will not accept a 512MB memory stick configuration. You may have to use 2-256MB DIMMs instead., See your user's manual.

Answer 8

i think you need to take it to a repair place or somewhere.
