Ok, so i got a XP2400 and I was under the impression that they came factory unlocked, so i tried to change the multiplier to any setting other than auto and the system wouldn't start. If i pushed the power button to turn it off and then turned it back on again it would load. The bios would say the multiplier was whatever it was set at last time, but windows would say 15. So i would turn the computer off to check the bios. Then the computer didn't start and had to repeat the "power button" process above. Is this something that is wrong with my kt333 or is my XP2400 not factory unlocked??

And can someone please tell me how to change the dividers, or at least tell me where some information it about is?

Jhoop I just got done reading some articles that go either way, some say no and some say that on a kt400 chipset they are unlocked.

hhmmmm, well, i guess mine is one of the ones thats not unlocked. S***!

Ok, so i can't change the multiplier, at least not until i unlock it. So i decided to see just how far I can go without changing the multiplier, i raised the fsb to 142 giving my 2600+ speeds 2.13 Ghz and got into windows and explorer wouldn't open up a web page. So then i said something has been pushed to far, so i changed the DRAM clock to 133 instead of 166 and here i am back on the internet. Can someone tell explain to me what the dram clock does??

I beleive it regulates the speed of which your fsb will run @, on that board I really cant push the fsb past 140 because it becomes to unstable, I have to up the voltages to make it run well at that speed but that produces more heat.
Find an artivle on how to unlock that baby, and as it has been said b4, after unlocking lower the multiplyer and rais that fsb

Hold on Jhoop, I am looking up your BIOS settings now.

EDIT: This is the manual I am reading from:
KT333 DRAGON Ultra Plus manual Rev: 1.0

I didn't find the manual to helpful, but this is what i got running right now, everything seems stable, and i upped the Vcore voltage to 1.7.

Ok, First make sure these settings are done.

Advanced User settings.
SOYO Combo Default setting.

Selecting “CPU Frequency Mode” to “Manual”.
(This is right under the Manual FSB setting)

You need to select the correct Divider from this table for the Frequency that your running on the FSB.

Example: For a FSB Frequency of 150-166 you need a Divider of 5.

ok i will try that, i must admit your a genius, i couldn't find it and BA couldn't either, but i gotta go eat so i will get to it as soon as i can.

Continuing because I can't add more then one pic above.

Make sure that the "SYSTEM PERFORMANCE" setting is Fast or Normal, not Turbo.

And this should help if you hadn't picked it all out yet.

just curious , why not turbo ? mine are on that just cuz I thot it was better.

It is better if your not overclocking, but if your running out of spec, optimized defaults are too finely tuned, you'll crash like a Heroin Addict in the County Lock-up.

um, maybe i'm just an idiot but i don't see that anywhere in my bios. I looked through my manual and the online one which is here http://soyousa.com/downloads/selectr...46&col3=Manual and i still couldn't find it.

EDIT:: Page 37 is where the manual starts talking about the bios and its the same as what i actually have except some things like the multiplier selections. I have more then this manual shows.

Looks like a diffent file, probably a different manual, I'll check it out.

Alright, I have something.

First, looks like I had the wrong manual, sorry Bro, My bad.

Second, I looked all the way through it and your right, there is no refrence to a divider setting for PCI/AGP. It looks like this board and BIOS does things a little differently.

This board is capable of an Asychronus Memory Bus.

This statement from page 18:
"On this motherboard, DRAM speed can be set independent
from the CPU front side bus speed."

I do not know if this setting automaticly sets the Divider, or if the Divider is locked.

But you can play with this, the only suggestion I have is don't use a slower DRAM speed then the FSB.

First, use a default setting, check WCPUID for the FSB and the DRAM Frequency. Then manually up your FSB about 3mhz and see if it has any effect on the DRAM Frequency. This should give you an indication of what you can and can't do.

In a way, it just makes your life simpler, and I can't tell you how it will perform.

Don't worry about reading the wrong manual, its not a problem.

I can tell you right now without looking in the bios. First off, your right about the DRAM speed being lower than the cpu frequency and that is not possible, the minimum for the DRAM is what the cpu is at.

Anyway,
there are several lines in the bios:
CPU : DRAM Frequency 133 : SPD +0
CPU Frequency Select 133 : MHz
Frequency 1 MHz Stepping 133
DRAM Clock By SPD
CPU Ratio Select Auto

That is for default for a fsb of 133, now when the DRAM clock is changed to 133 then,
CPU : DRAM Frequency 133 : 133
when it is changed to 166 then,
CPU : DRAM Frequency 133 : 166

when you increase the fsb by (lets say 7), with a DRAM at 133 you see:
CPU : DRAM Frequency 140 : 140
CPU Frequency Select 133
Frequency 1 MHz Stepping 140
DRAM Clock 133

now when the DRAM is set to 166, you see:
CPU : DRAM Frequency 140 : 173
CPU Frequency Select 133
Frequency 1 MHz Stepping 140
DRAM Clock 166


I still kinda don't understand why i had problems when the DRAM was set to 166. I thought that it only affected how fast info was sent from the ram to the cpu, now by raising that DRAM to 166 raised all the other frequencies such as AGP and PCI (which would make sense cause it shut off when i tryed to play music) then i kinda understand that.

I remember reading something about Asychronus Memory Bus but it kinda went over my head when i read it. Can you explain that a little bit??

I also got it to 2205 Ghz and everything seems stable. PCMark2002 ran fine .

Yea, well, by looking at this I can see the settings are having the following effect:

The DRAM Frquency isn't really setting a true frequency, it's adding or subtracking an additional speed from the HClock.

So, SPD is asychronous and will run at the Memory's rated speed.
133 = HClock (or the CPU frequency).
166 = HClock +33

That is why your last entry shows the HClock of 140 + 33mhz from the DRAM Clock 166 setting coming out to 173mhz for the DRAM Clock.
This is of course an asyncronous setting and will not gain you much performance because the CPU bandwidth limits what will be feed through the wider DRAM bandwidth. It won't hurt you, but it won't help much either unless it begins to effect stability.

Try benching it at 133 DRAM and 166 DRAM and see how it goes.

But if you stay asyncronous and you push the HClock for a good CPU OC, you will probably find your RAM will fail at the higher frequencies and limit how high you can get the CPU, and for no real benefit depending on your benchmark testing.

Although your current OC doesn't look bad at all.

thanks, I think i will keep it here for awhile to see if everything is as stable as it seems to be.
