Asus P5K Deluxe WiFi
3. The BIOS
The BIOS is familiar if you have used Asus boards before:
The Advanced Tab includes all the "goodies"
Entering the Jumperfree submenu:
While the latest (beta) 0404 Bios added more features (FSB Strap to North Bridge):
The DRAM Frequency has four memory dividers:
- DDR2-533 (1:1)
- DDR2-667 (4:5)
- DDR2-800 (2:3)
- DDR2-889 (3:5)
- DDR2-1067 (1:2)
What's rather convinient, is that as you overclock, more DRAM memory dividers become available, that help squeeze every drop from your memory modules:
Intel's P35 chipset offers 1T and 2T DRAM command rate. This should provide very good memory performance, in case your memory module supports 1T:
If you need to set the DRAM manually, many options are available:
There are many options in the BIOS to set voltages too:
| BIOS Setting | Feature: |
|---|---|
CPU Clock Multiplier |
6x-13x in 1X increments |
CPU bus frequency |
200 to 850MHz in 1MHz steps |
CPU voltage |
1.1000V-1.7000V in 0.0125V steps |
CPU PLL Voltage |
1.50/1.60/1.70/1.80V |
DRAM voltage |
1.800V to 2.55V in 0.05V steps |
PCI Express frequency |
100MHz to 150MHz in 1MHz steps |
SB voltage |
1.05/1.20V |
FSB Termination voltage |
1.20V to 1.50V in 0.10V steps |
NB Voltage Reference |
0.61/0.67x |
NB Voltage |
1.25/1.40/1.55/1.70v |
Finally, more BIOS options. Rather unusual that you can set the CPU Ratio from both the JumperFree and Advanced tabs:
