Question : Problem: Super P4DMS-6GM Issue: No Video + Beep Code

I am attempting to build the best server I can from parts lying around in our server room, and so far I have a Super P4DMS-6GM with dual Xeons installed along with 4 sticks of Kingston 1GB 184-Pin DDR SDRAM DDR 333 (PC 2700). I also have 2 sets of three same-sized Ultra3 drives connected and ready to have RAID set up. Also, there are 2 standard HDs connected to the same IDE cord and a standard CD drive on another.

My problem is that no matter how low I have the computer connected, starting with barebones, I cannot get any video out from the motherboard. Also, no matter the situation, there is a long repetitive beep that continues until I shut the computer down by holding in the power button for 5 seconds or unplugging it.

I initially thought it might be a RAM issue since the motherboard's manual says that a long beep means that it does not detect any memory. I figured this RAM may be too new and too fast, and therefore, tried every other stick in the closet to no avail.

What can I do/try to fix this?

It requires registered RAM: http://www.flytech.es/supermicro/Productos/Placas%20base%20Supermicro/E7500/Placa%20base%20Supermicro%20P4DMS-6GM.htm - like most server motherboards, you can't just install regular DDR memory in there.
