ASUS Rampage Formula X48 ATX Motherboard

The ASUS Rampage Formula is an ATX motherboard built on the Intel X48 chipset for LGA 775 processors. It supports DDR2 memory up to a maximum of 8GB. The board is supplied new without original packaging and includes a SATA cable and an I/O back panel.

Target users and limitations

This board suits builders assembling or repairing a legacy LGA 775 system that requires the X48 chipset and DDR2 memory. It is not for buyers who need a newer CPU socket, a different chipset, or memory types other than DDR2. The single SATA cable provided may not be enough for builds with multiple drives.

Deciding specification

The Intel X48 chipset paired with the LGA 775 socket defines which processors and DDR2 memory this motherboard can accept. Matching this chipset and socket to your CPU is the single factor that determines whether this is the correct part for your build.

Questions about this item

Will my existing DDR2 memory modules work with the 8GB maximum on this X48 board?

The motherboard supports DDR2 up to a total of 8GB, so any compatible DDR2 DIMMs you already own can be used within that limit.

How can I confirm the board posts correctly after installing it in my chassis?

Connect the included SATA cable and the supplied I/O back panel, power on the system, and watch for the BIOS splash screen or POST beep codes indicating a successful start.

Which accessories ship with the motherboard and what must I source myself?

The box contains the motherboard, one SATA cable, the metal battery and the chassis I/O back panel; CPU cooler, memory, power cables and any additional SATA cables are not included.
