setup is probably what most users will access to tweak the system. In our
tests, we first set it to Ultra, Manual, CAS 2, 4 Bank, 2-6-2 (TRas
can only be set to anything lower than 6). DRAM burst length was set to 8,
and the rest are similar to the screen shot above. The problem is the
3DMARK2001SE hangs many times. We later set the Fast Command to FAST and
everything is stable, the rest of the parameters set are as above.
The PCI bus frequency is selectable from
100Mhz to 250Mhz at 1Mhz stepping. It seems that although there is a
display only option of PCI/AGP Frequency, it seems that its derived value
is basically obtained by FSB multiply the divider by a ratio. There is no
way we can FIX the PCI/AGP to 33/66 as in SIS or nForce2 boards. Perhaps
newer bios can do that. If you use a 133mhz CPU (axp2400+), you can choose
anything higher than 165Mhz, if you use a 166Mhz CPU, you can choose up to
250mhz.
DRAM Clk can be set to
DDR266, 333 or 400. In our tests, we run AXP2700+ at both DDR333 (SYNC)
and DDR400 (ASYNC)
CPU Voltage can be increase
to 5%, 7.5% or 10% higher of default.
AGP Voltage can be increase by up to 0.3v
The same as AGP voltage,
DIMM voltage can be increase by up to 0.3v
