Upgrading RAM in Dell Dimens. E521 HELP

[angelxplaya]

Hi guys, I am very new to this, so I hope you guys don't mind my lack of knowledge in computer hardware and etc. Anyway, I am having trouble upgrading the memory on my brother's Dell Dimension E521 PC. I bought two 2GB crucial DDR2 240-pin memory sticks. I checked to see if it was compatible before I bought it of course. And it is. And I know the memory sticks work because I tried it on my own PC and it works fine.

Now, I have a Dell Vostro 200 Slim tower and I upgraded the same exact RAM to mine and it works perfectly. When I tried on my brother's PC, I powered it on and the screen is blank and it makes a funny beeping noise. Am I not installing it correctly? I replaced the old memory sticks and put the new ram exactly where the old ones were. The old ram were two 512MB mem sticks if that matters. Can anyone shed any light to this? I would really appreciate any help in this matter, I am such a novice at this.

Beeps after installing new memory usually means the motherboard doesn't recognize the RAM and is telling you there's none installed it can use.

First, did you buy this RAM from Crucial.com using their memory finder tool? If so, contact them because they guarantee compatibility if you go through that system.

If not, there are a few things to try. You have confirmed that the memory is good (functional) in your system, which is a plus. The first thing to do is try one stick of the new memory in his system. If it doesn't boot, try it in a different socket. If that doesn't work, try the other stick.

If you cannot get the new ram to boot in his system, try the sticks from your system in his box (you can always just put the new sticks in yours since you've already confirmed they work there). If that still doesn't work, it looks like it's time to RMA the sticks and use the crucial memory matcher (load on your brother's system and let it pick out the memory in the amount you want).
