Hello. I have just upgraded my MSI KT3 Ultra with a Barton XP2500+ and
Thermaltake Silentboost 7.
[Currently readings are as follows
XP1900 @ 1466Mhz.
Resting temp (in BIOS, side off case) 33 deg C
Used Artic Silver 5 so it should drop a bit more.
System temp (in BIOS, side off case) 32 deg C
CPU fan speed 2600rpm
I have PC2700 RAM at latency 2.5, set to SPD.
FSB 133, memory clock 133, AGP clock 55.5, PCI clock 33.3
CPU ratio set to auto]

I have found instructions to change the FSB, but it says
"make sure if your running at 133 that you dissable hostclk+33 first "
Where do I find hostclk+33 in my BIOS (v5.7)? I can't find it. Instructions
were at

Also, do I need to overclock the memory or something?


You do not need to overclock the memory, it is PC2700 which is correct
for a synchronous memory to FSB ratio of DDR, sometimes called 333MHz
but often called 166MHz at Double Data Rate.

See this review,
http://www.pcstats.com/articleview.c...eid=989&page=3
If your bios settings menus are still the same, the first picture
shows the memory speed as 333MHz when they used a DDR266 CPU. Focus
on that memory speed, don't try to change the rest of the settings to
match those in the review. The memory speed at 333 is at "+33" in the
example provided in the review, because they were using a DDR266 CPU.
It would be synchronously set at 266 or at "-33" at 200. However,
since you start out with a 166MHz, DDR333 FSB CPU, after manually
setting the CPU FSB to 166MHz (which is DDR333), you'd set the memory
also to 333, which wouldn't be "+33" anymore, would be synchronous to
the DDR333, 166MHz of the CPU FSB.

However some boards have bios bugs, where changing the CPU FSB doesn't
change the memory menu, so if your choices for memory don't change
after you increase the CPU FSB to 166MHz, choose the "middle" speed
setting of the three.

If the setting is difficult to set on the first try and your board
fails to POST, just clear the CMOS via the jumper (or remove battery
for a few mintures) and try again. If you don't have a printed
version of the motherboard manual handy it might be good to check the
online manual to see where the motherboard Clear CMOS jumper is before
trying to change these settings.
