hello there,

just bought some ram off ebay, 2 x 1GB samsung ddr400 dimm pc3200 modules. chip number is K4H510438B-TCB3. i've installed it into my dell dimension 3000 but when it boots there's a beeping noise, think it's a 2-.-. bios code, and the computer doesn't load. as far as I know the memory should be compatible?

any help much appreciated

Motherboard make/model?

Try them one at a time

Assuming that you have checked that it is ok for your pc (mobo documentation) I would just try one of the sticks as it may be a mismatch between the two sticks, failing that it may be worthwhile remembering not to buy this sort of thing from ebay and use a reputable source like Crucial for this kind of purchase.I hope this was not a too expensive mistake..

"This is the RAM type you are recommended to use. click here"

That's the type he's got!

Yes, sorry. I meant to say which is what you have got! Apols for the confusion.

cheers

Check the motherboard manual for details of memory acceptabilty - and which order you can install them.

the computer didn't come with a motherboard manual. not sure where to find it online?

You may find it on the Dell site - Support/downloads section, or search on the manufacturers site. Check out Motherboards .org for address - also computerhope site.
You should get the make/model from system Information [Start/Programs/Accessories/System Tools/], or by using Belarc (belarc.com) or similar 3rd party system info utility (AIDA, SiSoftSandra, etc.)
..Or you can open up the case and look, too.

"..just found out they're "high density". could this be the problem?"

Yes it certainly could. I keep forgetting this, as it wasn't an issue 3 years ago when I stopped building systems for a living.

The Dell documents I looked at didn't specify it either way - but since it's a motherboard from a year or two ago - it probably only taked low density RAM.
