ASUS A8N32-SLI Deluxe: BIOS Settings

Like all mainboards from ASUS, the A8N32-SLI Deluxe uses the AMI BIOS. The product is targeted at PC enthusiasts in the first place, so we’ve got plenty of settings here.

Almost any thing can be adjusted, although the adjustment of the voltage on the chipset’s North and South bridges is limited to adding 0.2V to the default value. Meanwhile, the voltage on the memory slots can be varied from 2.60 to 3.20V and the CPU voltage from 1.0 to 1.7625V. The CPU frequency multiplier can be adjusted from 4x to 25x. The PCI bus frequency is fixed at 33MHz, while the frequency of the PCI Express bus can be varied from 100 to 200MHz stepping 1MHz. The HyperTransport frequency range is very wide, but setting it to above 1000MHz makes the system hang up. This is probably some kind of reserve for the future, for upcoming cores from AMD, but so far these high frequencies are practically useless.

The number of memory subsystem settings is astonishing – you can adjust almost every parameter imaginable. CAS Latency can be set at 1.5 to improve a little the performance of PC2700, but this mode is rather too aggressive for PC3200 modules. The memory frequency range is 100-250MHz. Since AMD’s CPUs have an integrated memory controller, you can use frequencies above 200MHz only with revision E cores that support DDR500 SDRAM (see our article called AMD Athlon 64 Processors on E Core: Memory Controller Peculiarities in Detail ).

We have only one complaint about the Power page – it shows the speeds of only three fans, including the CPU cooler’s. Otherwise, the options are typical enough. Note that you can turn on ASUS Q-FAN technology from here.

The BIOS of the A8N32-SLI Deluxe allows you to change the logotype displayed at the start of the system with a custom image (MyLogo2 technology) and also supports Crashfree BIOS 2 technology whose point is to restore the contents of a corrupted BIOS chip by means of a special image from a CD or diskette. This solution is much simpler than the additional chip other mainboard makers use as it doesn’t require hardware modification of the mainboard, but it won’t help if the BIOS chip is physically damaged.
