i've had a bit of a go at it, and i got my 3500+ venice to 2.5.
i used 250 x 10 to get this but i havn't much of an idea about setting a divider. and when i checked on the asus monitor my ram was in the red bit. and the voltages were on the max it would let me which i think was 1.525

i'd like to get it to 2.6 or even 2.7 if it will let me. i've had it at 2.6 but it wasnt stable. got in to windows but it wouldnt complete 3dmark without freezing.

my hardware is :-
3500+ venice
Asus A8N-SLi Deluxe nForce4 SLi
Corsair 2GB DDR XMS3200C2PT TwinX (2x1GB) CAS2
xp-120 cooler

i think i've been on the right track a few times and have nearly managed it, but i just cant seem to squeeze what i want out of it.

im not sure but would increasing my ram timings and voltages let me get a more stable fsb? and is a divider setting the rams max clock speed lower?

if you have time could you please point me in the right direction as i dont want to kill any of my stuff :)

im aiming for 237 x 11. i dont know if theres a btter way of doing it, lower multi higher fsb. but a bit of advice from someone with a similar system would be helpfull

thanks for reading.

Everybody makes this mistake to start with... Overclock ONE THING AT A TIME.

If you are overclocking your RAM, mobo and CPU all at once how are you ever going to track down and fix any instability?

Isolate your components. So, when looking to see how fast your CPU can run stable you want to stick your RAM on a divider so that it ALWAYS remains well within its limits. This way you'll be able to find your max CPU overclock while being sure that nothing else is making your system unstable. You can then find the max speed of your RAM by using a low multiplier on the CPU to keep it well within its limits while pushing the FSB (or HTT as I believe it's called on these new-fangled A64s - I'm still on an Athlon, so details might be a tad off but the principles remain the same)

Basically if your system fails when you've adjusted several things you'll never know which setting caused the instability. If you change one thing and it becomes unstable then your answer is right there. Find the limit of each component in isolation, then set your system accordingly.

Also, don't expect a major RAM overclock with 2Gigs

The opposite is true. :)

A higher FSB and lower multi means the components are under more stress at the same clock as a lower FSB and higher multi.

11*100 is under less stress than 10*110.

Increasing the chipset voltage will allow your components to be stable at higher speeds.

If your timings are slacker, you will be able to get it running at a quicker speed, however some applications prefer tighter timings to speed. Some applications work the other way though, and prefer more bandwidth.

Within a certain range, increasing the voltage will allow you to get quicker speeds and tighter timings, however when you get too high the voltage just makes the memory too hot and thus decreases the amount you can push it.

A divider will allow you to increase the FSB more since processors can usually be pushed further than RAM. A 200MHz divider will run your memory at 200MHz when the FSB is 200MHz, and 240MHz when the FSB is 240MHz. A 166MHz divider will run your memory at 166MHz when the FSB is 200MHz, and 200MHz when the FSB is 240MHz (stock).

Make sure you change the command rate to 1T, works much better with A64s. :)
