The motherboard is the backbone of your computer that connects to all other devices.
The Asus P5e and P5e Deluxe motherboards feature many similarities. However, there are certain differences that can affect your choice to buy either one. Before purchasing one of these motherboards, research the differences between them and decide which one is right for your computer. This decision determines which kind of processors and memory your computer can use.
Processor Support
Both the P5e and P5e Deluxe support Core2Duo, Core2Quad, and Core2Extreme processors. The P5e also supports the older Pentium 4, Pentium EE, and Pentium D processors.
Memory Support
The P5e supports memory clocked at 1,066 MHz, but allows this memory to be overclocked to 1,200 Mhz. Overclocking memory may cause overheating and device failure, but allows for higher speeds. In contrast, the P5e Deluxe supports memory clocked at 1,200 Mhz, with no overclocking required.
Northbridge Chipset
The P5e Deluxe uses the Intel X48 Northbridge chipset, which connects the processor, memory and advanced graphics port. The P5e uses the slightly older Intel X38 Northbridge chipset.
Hyper Threading Support
The P5e supports hyper threading, a feature found in Pentium 4 processors but absent in Core2Duo processors. The P5e Deluxe does not support the Pentium 4 processor, and does not support hyper threading.
