Asus P5N-E SLI Motherboard Review :: BIOS and Overclocking

The ASUS P5N-E SLI motherboard uses a modified version of the Phoenix Award BIOS that they like to use in their motherboards. The BIOS is split into the standard Main, Advanced, Power, Boot, Tools and Exit. The Main menu is where the system information including the Time, Date, Language, whether the system uses a Legacy Diskette A like 720KB floppy disks, Primary and Secondary IDE channels, HDD SMART monitoring and the total installed memory on the system.

The Advanced area of the BIOS is where the primary overclocking and tweaking on the board is done. The JumperFree Configuration is where the CPU overclocking is done. AI Tuning has Manual, Auto, Standard and AI Overclocking as its options. AI Overclocking has preset overclocks for the CPU of 5%, 10%, 15% and 20%. PCI Express Frequency can be set from 100MHz-131MHz in 1MHz increments.

Voltage options are set in the Voltage Controls area. The VCore Voltage can be set from 0.83125V to 1.60000V in 0.0125V increments. Memory voltage can be set from 1.920V-2.517V. NB Core Voltage can be set from 1.208V to 1.748V. The VCore Offset Voltage can be set to +100mV.

The FSB and Memory Configuration screen is the next item on the BIOS. Here you can set the FSB-Memory Clock to either auto, Linked or Unlinked. Linked means the FSB and memory clocks are linked, if you raise one, you raise the other. Unlinked means you can adjust one without affecting the other. The FSB/Memory Ratio is also set here. The options are 1:1, 5:4, 3:2 or Synced. The final option in this area of the BIOS is the FSB QDR MHz speed, 800MHz in the case of the Pentium 670 CPU.

CPUZ Overclocked


Overclocking the board was a breeze with few problems. The system would boot at the 20% overclock on the AI Overclock menu, but it wasn't stable at that frequency (4.56 GHz). The P5N-E SLI was completely stable at a 10% overclock (4.18GHz) but at 15% it was unstable running any demanding application. The limiting factor here is the CPU, not the board, as no Intel CPU was released past the 3.8GHz clock speed.
