Not enough Ram?

[Flyer1010]

This is my first experience building a PC

System:
Gigabyte GA-P55A-UD4P
Intel Core i7-860 (quad-core)
Crucial 8192MB (8GB) PC3-12800 DDR3
eVGA Geforce GTX 260 Core 216 896MB DDR3 PCI-E
Western Digital 1000GB 7200rpm SATA

At my first boot, a long constant beeping sound occurred. My first thought went to the installation of the ram. When I ordered the Crucial DDR3, only one stick arrived.

Should I have received two?

I saw in the installation instructions they he used a DDR2 and 3. Do I need to order another so I do not have this beeping noise anymore?

(written later)
After re-reading my Motherboard's manual, I found that a long continuous beep is the graphics card. So I guess I will need to check both tomorrow morning.

All help is appreciated.

Something's not right. Crucial doesn't seem to make an 8gb kit of DDR3 12800.
Maybe you ordered two 4gb kits. I don't know. One thing is for sure, 8gb is far more ram than you need.

Ricky,

This is the Ram I ordered:

This morning I cleared the CMOS. I took out the Ram, turned the computer on, same long, continuous beeping noise.

Took out the video card. Same beep.

I even moved the RAM to slot 3 (manual says 1 and 3 are fine for one RAM module)

I reinstalled everything, and when I turn the system on, I receive a long series of fast, short beeps.

The manual states that this is a problem with power. How can this be? All the fans turn on and the motherboard lights up.

At the corner of the motherboard near the processor is an 8 pin power connector. Do you have a connection there?
