i noticed in the test setup that toms hardware used a KT333 mobo to test the new chips...the chip has a 166 clock. Does this mean that the KT333 boards can take a chip with a 166 clock? someone prove to me they know what they are talking about....(cause i see a lot of people round these parts just using lots of fancy lingo who may not know what it all means)

but does this mean i just set the clock speed on the mobo higher and thats that?

By clock speed I'm assuming that you're talking about the FSB(front side bus). In which case, yes, in theory all that you really do is set your mobo to use it and violla.

In reality though, since your processor's speed is the FSB times the multiplier, raising the FSB raises the speed at which your CPU runs. The CPU might not like this, and with an Athlon, if you don't have several layers of good thermal protection (a big-arsed heat sink with a copper base and a powerful fan, Arctic Silver thermal paste, and a motherboard that will actually read your CPUs on-die temp and shut the system off if that temp exceeds a set limit) you may end up with a fried Athlon.

So you may have to unlock the CPU so that you can lower the multiplier, and thus put the CPU back to it's rated GHz.

On top of that, not all models of the Athlon chip itself (especially really old ones) aren't guaranteed to like being run with a higher FSB.

So yes, the KT333 chipset can support a 166MHz FSB. Whether the rest of your system can is a completely different question however. :)

i wasn't exactly clear with my question OR i don't understand how multipliers work. I'm talking about putting one the new AXPs (2500+, 2600+) on a KT333 mobo. In this case I see you would up the fsb to 166 (since this is what the chip is meant to operate at) but would any multipliers have to be changed?

I believe you're mistaken. The 2400+ and 2600+ are still using a 133/266MHz FSB, not a 166MHz/333MHz FSB as you're thinking. So pretty much you would use the same settings that you would for any other AXP. (Voltage might be the only real difference.) No need to change the FSB or the multiplier.

If you change the FSB to 166MHz/333MHz you are overclocking your chip and may need to mess with other settings to get the chip to run happily.

As far as I understand it, the XP2600+ operates at 2133MHz - which is 16 x 133MHz. All the Athlon XP's are specified by AMD to work with a 133MHz bus. (Although the article on Tom's about the 2600+ didn't exactly make this clear)

So, running any Athlon XP with a FSB greater than 133MHz is overclocking it. Depending on the chip (since they all overclock slightly differently), in order to run it at FSB of 166MHz, it *might* need to be unlocked and the multiplier set lower than it was originally locked at.

ah yes, upon rereading some of the article i see why i was confused.

*might* need to unlocked? why wouldn't it?

133MHz (266MT/s)
166MHz (333MT/s)

if would be nice if everyone begin using MT/s instead of MHz. that way we get to educate a few people. that's just me though.

Educating a few people would be nice, but I gave up on trying hard to achive this particular education a long time ago. When it first started up and people were claiming DDR was 200MHz and all that jazz, I fought the system hard.

In the end, too many people listen to marketting. I just didn't have the heart to keep up.

MT/s is a nice concept and a fresh new way to attack the problem, but I'm still partial to 2x133MHz myself just so that we 1) know how many pumpings are used and 2) know the true clock speed.

In the end though, I just started using 133/266 to avoid all of the hassle of explaining myself repeatedly.

Good luck educating the masses though.

first of all, in <A HREF="http://www.tomshardware.com/cpu/02q3/020821/athlonxp-06.html" target="_new">this chart on this page</A>, you will see that the FSB is 133 under the T-bred B.

Now, the reason your CPU might not need unlocking would be if it is capable of handeling running 25% faster than it's rated speed stably. It took THG watercooling to get that to happen on the test bed, but who knows with the 2400+ if it will be able to do it with air cooling.
