Ok i have tried to read as much as i could about over clocking before i finaly decided to post here. OC is the only thing i never really got into until recently after reading so much about it.

My current rig is set up as follows

XP 2500+ Barton ( stock 1.83 currently 2.0 )
1 gig ( 2X512 mg ) PC 3200 kingston CL3 ram
Asus A7V8X-X mobo
Gainward Geforce 4 Ti 4800 Se 128 mgs ( FX 5900 Ultra 256 mg on its way )
Soundblaster Audigy Gamer
30 gig Maxtor HD 7200 rpm (upgrading this shortly)
WinXP Corperate Edition

Ok now the problem im having currently is this. I can not seem to get my computer to run over 2.0 ghz ( live speed check is more or less 1997 mhz )
Even though in the bios i switch the memmeroy settings from 166/33 to 177/35 it still only shows in windows as 2.0ghz and with wcpuid as 1999.77 with a a 166.65 system clock speed. The multiple is set at 12x so with the current bios settings i should be running at 2124 mhz.

I havent up my vcore yet to test other settings because i havent gotten away from my stock heatsink and fan yet. But if i try a multiple higher then 12 at any clock speed it doesnt wanna boot.

So my question is since i have seen so many people clock these 2500+ up to 2.5 ghz is what are the best settings with the mobo i have to get that type of speed out of this processor. And what would be a good current speed with the stock heat sink and fan?

The case has 7 fans total keeping it cool i have made sure it is evenly coming in and out.

Any suggestions?
 
well. that is not a bad overclock at all for stock voltage. I know that Tbred often can throw up 200-300MHz on stock vcore. Bartons although are a slightly different.
Maybe you can enlighten us on your current temperatures ?
I suggest that speedfan is your best option to get temperature...which is found...here:
http://www.almico.com/speedfan421.exe
I do not believe that many people on air can get a 2500+ barton to 2.5..im sorry. Possibly 2.4...but with air, bartons run very hot.
Consider investing into the new heatsink, find out your temps and go from there.
If your temps load are in the 40's i suggest throwing a 0.5v increase and put some more juice into that baby
oh and i almost forgot:
WELCOME TO THE FORUMS!
 
yea you would be VERY lucky if you managed to even hit 2.4 on air. 2.5 is out of the question unless you lived in the antartic @ night haha.

Edit: im sorry i didnt read your post correctly. Bartons and Mobile bartons are different stories. the mobiles are a LOT lower voltage and less heat consumption. they cannot be compared for overclocks really..
 
Yea i dont believe they got it off air cooling like that, or if they did they mentioned a specific thermal paste and a massive cooling fan.

I plan on getting a better cooling system expecialy if i plan to over clock that high. I was hoping to get it to at the least a 3000+ setting which would be a 2.16 ghz. The problem im running into currently is that even though the processor should be reading the clock speed at 177/35 and a multiplier of 12.0 it only reads my first overclock which was 12.0 multiplier and 166/33 clock. No matter what i put my clock at it always reads in XP and wcpuid as 12.0 166/33.

I was wandering why it wouldnt read it any higher even though according to the multiplier and clock it should be 2124 or so. Eventualy im going to try and up the vcore settings once i get the right cooling in there, but for now would like to get it at lease a 2.16 ghz like the 3000+.

And last i checked temp was 45c not to sure as i uninstalled the monitoring program i had. I need to reinstall it.

Thanks for the help in advance.

When you say 166/33 i am correct in saying you do not have a PCI/agp lock on that motherboard...or am i wrong?
 
Your board supports a FSB of 200, doesn't it? Why not try the old tried&true 11x200 for 2.2GHz. Most XP2500s can do that with little increased vcore.

You're going to have to get that FSB up for a better OC and you do have PC3200 RAM. At 200 you won't have to worry about PCI/AGP speeds because the correct divider should kick in automatically.

Are you sure that your chip is unlocked? If it's locked that would explain why going to 12x didn't work.

I have tried going to 11.0/200 but the computer doesnt boot after that. Any multiplier other then 12.0 and the computer doesnt respond well, it either doesnt boot or wont load windows.

the 166/33 are my options in the bios of the AV87X-X asus mobo. I'm very computer literate, but overclocking is a whole new world to me. I couldnt tell you wether the processor is locked or unlocked, i do know i have been able to clock it to 2.0 ghz thus far with no problems.

The options for the clock speed goes up in incriments of 1 so i can literaly go from 166 to 167 ect and so on. That is why i tried a clock setting of 177/35 but the computer didnt recognize it. So i am assuming even though the bios says its there its truely not unlocked like that?
 
Your barton will be locked. you would be VERY lucky if you somehow got an unlocked one. If it doesnt boot with a higher/lower multipliers, its 99% locked.
Try this: Boot 5MHz higher fsb (171fsb) Run Prime95, which is located here:
ftp://mersenne.org/gimps/p95v238.exe
If it passes, (let it run for at least an hour) then boot further, when prime throws an error at you under 1minute in...you know your unstable and now you can add a lil voltage.
 
Thanks ps2cho for the advice with the program. The thing is currently the clock speed in the bios is 177/35, but when in windows and i run the wcpuid it says the clock speed is 166/33 even though in the bios it isnt. It will boot pretty much at any clock speed, it just doesnt recognize that its a diff clock speed outside of the bios?
 
That board doesnt have a pci lock.The best thing is to try going for the kill and setting the fsb to 200.If that doesnt boot or crashes give it some more voltage till it does.You shouldn't have to give it more than 1.7 or 1.75v to be stable 2.2 ghz.
 
you CAN get 2.5GHz on air with a barton 2500+. it just takes alot of volts and a nice cool day with an open case. :D
 
Yes and a lot of volts wont make that chip run for long...as i have experienced with my tbred now, as it wont hit 2.2 like it used to...i still need to reseat and re-as5 it.
 
Have you tried OC in Windoze??? I use Gigabyte mobo's and they come with a program called EasyTune4
(http://www.giga-byte.com/MotherBoard/FileList/NewTech/tech_ez4_hlp_intro.htm). You can always try EasyTune with your rig and if it will not work it will most likely give you a message like "This mobo not supported." Surely there are other programs you can find that will do the same thing.

Seems odd that you have PC3200 RAM and cannot get this Barton running with a 200 MHZ FSB??? My old rig, an XP1800+ Pal, wouldn't go up at all at first and it turned out that the RAM was not PC2700 but PC2100! (It was labled 2700 though.) Can you try a buddies RAM in your rig or yours in his??? Also, try using just one of your sticks in your system with the other one out and then try increasing your FSB (still nothing, try switching the sticks out). Hopefully, if ... this is any part of the problem then you are not stuck with 2 sticks of RAM that will not run at PC3200 speeds.
 
Dah, I forgot to put this in: the thing about EasyTune4 is that you will start with the speeds set in the BIOS and then you can increase FSB 1 MHz at a time or jump it straight up to 200 or more. You can also adjust voltage of the DIMMs, AGP, PCI from this program as well as watch CPU/system heat & fan rpms. It's a good program to use because you don't have to keep rebooting your rig with every change you make ... your already in Windoze. After you find a stable setting in EasyTune you then go into the BIOS and set the values there.
 
Thank you all for your help, i will try uping the voltage later tonite and see if it will boot at 200mhz. I will also have to take a look at that program, this is all still knew to me as i never felt i needed to oc before. But recently wanted to get more out of my 2500 before going into a amd 64 eventualy.

I will let you guys know the results as soon as i get home.
 
Forget about that windows program because if you start upping the fsb 1 by 1 without a pci lock your going to run into problems eventually.
Go strait to 200 fsb in the bios.If it doesnt boot or crashes in windows go back and set the the vcore to 1.7v.Then 1.75 if needed.
If you have to go past 1.75v on that chip it would be very suprising too me.
 
I buckled down and picked up a volcano 7 heatsink and fan today. It seems to come with a switch for the fan to run at different speeds which is pretty cool. In about an hour or so i should be getting home and trieing to take the processor to 2400 mhz.
