512mb+512mb=?

Today i recieved a, or shall i say two, 512 mb DDR RAM chips. When installing both at the same time, my screen became, just a screen with a box saying that the monitor was OK but it probably wasn't pluged into the computer. Well, i toyed around with the problem. First i put just one at a time in. WOOT! it works. ok, now i just to put in the other one. put it in, that stupid screen again. So then i put in the original RAM that i had before (256 mb DDR) and what-do-ya-know, it works. so then i begin to think its just a bad chip. so then i put in the RAM that i thought was bad by itself, and then with the old RAM. IT WORKS!!! Then i try putting it into different slots, and it comes out the slots are just fine. Finally comming to this award winning essay's end, I have come to the conclusion that is it possible that my baby (or computer, whatever you wanna call it) can't hold over a Gig of memory? Is this true? Only you guys can help me...and the manufacturer which is only a call away, but i would have to wait till tomarrow because it's Christmas.

BTW this is a good messege board, i dont even play this game, but theres a lot of intelligent peoples here. After visiting the topic about the graphics card, (which i still haven't figured out yet) i can really post my pc problems here.

Hello DangerBunny367

We will need some more details like mobo and graphics

Oh and youre running XP right?

There are a lot of p***ed off people on this site at present(keeping out of that one)so try not to upset any more by calling FS a game.......ITS A SIM

There sorry for shouting

Could I ask what motherboard you are using? Roughly how old is it? Also, are there more that 2 slots for memory chips? If so, sometimes they have to be 'paired'.

Well, first of all, sorry about calling it a game. I really don't know anything about the, SIM. I have just heard about it a couple times, and heard it was pretty cool. About the mobo, I dont really know. Im sorta a newb, and i don't know everything about my pc, and where to find it. I do know it's a Compaq Presario 6000, and i purchased it about a year and ¾ ago. It's really outa date. Rigth now im running XP on it.

BTW there's only two slots...

Are the two chips you purchased EXACTLY the same architecture? Same make, model, size, speed...etc?

Yup, both DDR DIM 512

Well, in that case - I am guessing your motherboard cannot take 1024MB of memory. If you could find out the motherboard model - we could confirm this.

well, i called the manufacturer and he said the model of my comp can hold that much, and he then told me to call compaq. so i did and i went through like 20 min of pressing keys on the phone for the automatic operater, and being on hold. and i kept getting this guy from Arabia, and i couldnt understand him. so yes, my computer can hold over a gig of memory

Can you test the memory in another machine?

It might be a faulty chip as i was running 2x256 sticks and would only show as 470 or something but run them on there own and both showed 256

I had a couple of 128 sticks and with trial and error found the faulty stick

( HHMMM buying of Ebay )

Let us know

Go to this site and you can enter your computers specs to see if your MBoard can take that much ram.
If you can call them they'll will help you.

Good company good prices good luck.

Yep they are one of the best and its free P&P at the moment

I think this is because something in your comp (possibly onboard grx or video card) is using shared graphics

take out your graphics card before you put the memory stick into the slot then put the sticks in and then replace your video card a viola that is all there is to it
