I also noticed that if I put three of the Crucial sticks in (two in blue and one in white) and also put one of the old Kingston KVR133D3N9/2G in the other white, it works fine two. &nbsp;

I have an ASUS P5P43TD PRO motherboard. &nbsp;It has four slots, two blue and two white. &nbsp;It originally had two 2gb sticks of Kingston KVR 133D3N9/2G (<a href="http://www.ec.kingston.com/ecom/configurator_new/partsinfo.asp?root=&LinkBack=&ktcpartno=KVR1333D3N9/4G&id=2" rel="ugc">http://www.ec.kingston.com/ecom/configurator_new/partsinfo.asp?root=&LinkBack=&ktcpartno=KVR1333D3N9/4G&id=2</a>) in it. &nbsp;Online, it says the motherboard can have a maximum of 16GB. &nbsp;I purchased four 4gb Crucial CT2KIT51264BA1339 (<a href="http://www.crucial.com/store/mpartspecs.aspx?mtbpoid=DA1BDDDEA5CA7304" rel="ugc">http://www.crucial.com/store/mpartspecs.aspx?mtbpoid=DA1BDDDEA5CA7304</a>). &nbsp;When I placed all four sticks in, the server started beeping and not booting at all. &nbsp;Then I removed two sticks from both white slots, and it booted up fine. &nbsp;I tried it again, and still the same issue.<br />

RAM not working

Servers are computing devices that are similar to desktop computers in that they have the same basic components, but are significantly different in size, configuration and purpose. Servers are usually accessed over a network, and many run unattended, without a computer monitor, input device, audio hardware or USB interfaces. Many servers do not have a graphical user interface (GUI), and are configured and managed remotely. Servers typically include hardware redundancy such as dual power supplies, RAID disk systems, and ECC memory, along with extensive pre-boot memory testing and verification. Critical components might be hot swappable, and to guard against overheating, servers might have more powerful fans or use water cooling.

Server Hardware

Hardware includes cell phones and other digital living devices, tablets, computers, servers, peripherals and components, printers and scanners, gaming consoles, networking hardware such as routers, hubs, switches and modems, storage devices and security equipment such as firewalls and other appliances.
