Newbie to Overclocking - Advice please on a XP2000 and a7v333 Mobo?

I have a XP2000+ Thoroughbred B core CPU nd a Asus A7V333-X mobo.
I also have PC2700 DDR (333) ram.

As I understand it the actual Mhz on this CPU is 266.
If I up it, will I notice a big improvement in performance?

If so, how do I go about doing the overclock?

FYI
As I understand it the FSB * Multiplier = CPU Speed
So on my XP2000 it would be 133 * 12.5 = 1667

Do I up the FSB or the multiplier


cheers

try to speed up your FSB... I think 166 should be ok.
If you ram is 333 it should work in synchronous mode.
My Athlon 2500+ is 11*166 so you'll get even more than this

Good luck

I would say both but 166mhz x 12.5 should work (and maybe up to a max of
about 180Mhz but you might have to increase the vcore a bit to get the cpu
to run stable - I used to run my A core 1800+ in my a7v333 at 166fsb and a
bit beyond.
But 12.5 x 166 limits you to 2075mhz even 172 x 12.5 is only 2150mhz - the B
core might go to 2400mhz so I would suggest looking into accessing the
higher multipliers a tried and tested way is the pin mod guide at

http://www.ocinside.de/go_e.html?/ht...md_pinmod.html

14 x 167 seems to work for me @ 2340mhz and 1.85v vcore

yeah try bumping your fsb straight to 166 your ram pc2700 is rated at this
just depends if your processor core will handle the speed increase.

Thanks for the replies guys.

If I up the FSB to 166 will I stress the PCI cards at all (eg Is the
PCI Bus increased as I up the FSB)?

thanks again

Harry

Hopefully not 100, 133, 166, 200 should use the same PCI/AGP frequency
(33/66). On the other hand my motherboard doesn't allow me to change FSB
from 166 to 200 without changing PCI/AGP speed so I guess you have to try
it for yorself.

Well I got the FSB upto 159 stable, before windows crashed.

I did have it at 166 (33/66) for 5 minutes but it was far too
unstable.

Ideally I want to see if running it at 166 (in synchronous mode with
the 2700 RAM) will give me a greater performance boost.

What other things can I do to get it stable at 166? So far I have only
upped the FSB but I didnt touch the Muiltiplier or Vcore. Any help
would be greatly appreciated.

cheers

Harry

The first thing I would try would be to up the vcore one stage at a time and
see if it runs stable - if it is a 'b' core it should get well over 2000MHz.

Have you tried seeing how fast the fsb will go - by using a very low
multiplier in order to check how fast you can run it.

You may try setting any memory timings to 'normal' or safe - try not using
the faster timings - or set them manually to the biggest values there are eg
3.5.5.8 and seeing if that lets it run faster, then start making the values
smaller until it is unstable

I do not think increasing the ram voltage will help - I have an A7V333 (non
X) where the ram voltage is 2.78-2.85v - so it is overvolted by default (the
undocumented jumpers J1 & J2 determine memory voltage)

a better performance boost than having the fsb at 166mhz would be having the
fsb at 166mhz and increasing the multiplier
