Well, it's a nightmare for me anyway. So I wanted to upgrade my computer. I ordered everything, and the first thing to arrive was RAM. My original RDRAM was two sticks of 128 MB RDRAM (40ns) in rimms 1 and 2. Rimms 3 and 4 had continuity modules. As far as i can tell, the RAM is non ECC, unbuffered, PC800. I have a 533 MHz FSB. I ordered two sticks of 256MB (made by Samsung, because that is who teh original RAM was made by). This is the specific RAM i got : http://www.newegg.com/app/ViewProductDesc.asp?description=20-151-102&depa=1 I opened my case, popped out the continuity modules and put in my brand new RDRAM. I plugged it back in, fired it up and all I got were ten distinct beeps. So I thought to go to Dell's support forum. I am told there i need to put the larger RAM sticks in rimms 1 and 2. SO i popped out the older 128s, put them in RIMMS 3 and 4, and stuck teh new 256 sticks in rimms 1 and 2. Still, all I got were the beeps. So, lastly, I put the continuity modules back in RIMMS 3 and 4 and put my new sticks of RAM in 1 and 2. Still, all I got were the beeps, without a system boot up. So, oh great members of the techspot forums, did I get faulty RAM? Or is it something more sinister. I was told on the Dell forums that this RAM should work, so I don't know what to do.
