First of all, you can overclock this CPU simply by raising
the FSB within the bios of the KT7 RAID (or jumpers
depending on what motherboard you have purchased.) However, with such a low multiplier, the
Duron 700 will not reach the 1Ghz plateau with FSB increases. Therefore, the clock multiplier
will have to be raised, unfortunately, the L1 bridges on the CPU have been cut
by AMD. However there is no need to be worried, a simple pencil can
be used to reconnect the L1 bridges.
The pencil trick is reasonably simple, however the bridges
are tiny, and great care must be taken whence connecting them with the pencil
lead. I suggest using a very fine tip pencil tip, or one of the .5mm
mechanical pencils. Just pencil the bridges back and forth a few times,
and that should provide enough conductivity to unlock the CPU. After
successfully connecting the L1 bridges, the clock multipliers can now be
accessed and modified within the BIOS (or jumpers if the bios on your
motherboard does not support clock multiplier adjustments.)
I ran into some
trouble when setting the clock multiplier to 10X with ABIT KT7 RAID, it would
post and get into Windows 98 SE just fine, but there was one small problem, the
clock speed was only 900Mhz! I bumped up the clock multiplier to 10.5X,
and it posted at 950Mhz, going on a little hunch, I bumped
it up to 11X, and voila it posted and booted into Windows
98 SE at 1000Mhz! Stability was a bit questionable, so I had to go back
into the bios to adjust the Vcore voltage to 1.825V. One reboot, and a
100 frags later, I determined this CPU to be rock stable at 1Ghz
@ 1.825V.
So I thought to myself, how else can I increase the performance of
this CPU? Knowing that 1Ghz was the realistic limit on any Duron processor
with traditional air cooling, I decided to lower the clock multiplier to 10X
(effectively 9X on this motherboard,) and raised the FSB to 112 to get a CPU
core speed of 1008Mhz. I considered this to be reasonably close to the
1Ghz barrier, and surely the FSB increase would improve performance, or at least
memory performance.
