The KT266A has can support for up to 4 GB of PC1600/2100
DDR RAM, but as the AN11 Stealth only has three DIMM slots, it is limited to just
3 GB of non-ECC PC1600/PC2100 DDR RAM. During testing we installed three 256MB double sided
DIMM's and experienced no memory related issues or problems.
First International Computer (aka FIC) have chosen to use
the Award BIOS for their AN11 Stealth motherboard. After
a quick look around the BIOS I was happy to see that there are quite a
few memory tweaks available. Overclocking options were limited
With the ability to adjust memory speed from either 100 or 133 MHz, and the ability
to change CAS Latency and bank interleaving, the AN11 Stealth should keep any memory tweaker happy.
As we can see, the overclocking options are quite limited.
FIC have stated that they're not trying to target the enthusiast market with
this board and that's fine - not every motherboard has to be built to
satisfy 3% or 5% of consumers. . We did notice something very interesting when
looking at the FSB speeds shown above... According to the AN11's BIOS, when the
board is running at 166 MHz FSB, the PCI speed is 33 MHz! Does the AN11
have an unofficial 1/5 PCI divider since the KT266A doesn't support this? We're
not really sure, and since there aren't any multiplier controls, we couldn't bump
up our FSB to 166 MHz even though the DDR RAM we tested with the AN11 could
have run at that speed.
As for overclocking the unlocked
AthlonXP 1900+ we used for testing was detected as a XP 2000+, and since we
are now using a 12.5 multiplier, the highest we could push the AN11 was to 140
MHz FSB. Anything higher and the system would have a hard time
