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?
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..
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.
