Shuttle AV40R (1)
Overclocker 1 Oct 2001
Shuttle has made in roads to the Athlon boards
with it's award winning AK31 rev 2.0. To date, Intel has only introduced
Brookdale (i845) which does paralysed the P4 system performance with bundling it
with SDRAM. The problem with SDRAM is that it deters the real performance of the
Pentium 4. As we can see, the next logical step would be to go with DDR, but
Intel only licensed this technology to SiS and ALi. That is also why you don't
see many manufacturers producing P4 DDR boards using P4x266 which is still in a
licensing battle. Shuttle has made a bold move by adopting the VIA P4X266
chipset for the fresh Pentium 4 supporting the DDR modules.
Shuttle has adopted the suggestions from users
and webmasters by introducing a P4 board which has all the overclocking features
built in. While some prefers using the jumpers, Shuttle introduced all of the
following options that can be tweak within the BIOS.
BIOS FSB step-less setting from 100MHz to
166MHz with 1 MHz increment
CPU core voltage setting from +0.025V ~ +0.20V
AGP (Vddq) voltage setting from +0.05V ~ +0.20V
I/O voltage setting from +0.1V ~0.2V
