Do these cpu stats look OK ?

[erger]

Hi all

I have just swapped my mobo and cpu for a gigabyte kt400 and athlon xp 2200+ combination.

I am confused about the fsb settings and at the moment i have the core volts up 5% so it is stable? If it looks OK thats fine but at the moment i am not sure...

Thanks for any comments.

Chris

Your question is "is it stable"?

Somebody will probably just post

but to answer your specific question:

To test the stability of overclocked CPU:

Double click on PRIME95.EXE to start the program.

Just Stress Testing (if prompted) > OK >
Options > Torture Test


The program should not give any errors.
It may be necessery to run the program 12-24 hours to make sure an overclocked system is stable (no program errors displayed).


If you get errors only after several hours, this is a result of slight instability because the system is running with little or no margin. It's stable enough to boot and moderate stress, but as soon as the system is under enough load to go over that critical point, it will freeze. To be 100% stable, Prime95 should run 12-24 hours without any errors.

You wouldn't need to up the vcore to run stable at stock speeds. Unless it just refuses to run good at default vcore, you're just adding needless heat. On your cpu, there should be a black sticker. Whats it say?

Careful raising the fsb on that kt400. There isn't a pci/agp lock, so you start running out of spec for your pci devices and agp card. That can result in a dead agp card and corrupted hard drive if you over do it. Personally I couldn't do higher than 180fsb on my gigabyte 7vaxp. A multiplier overclock is probably much more practical on those boards.

Welcome to the Forum!

Your chip is also a Thoroughbred "A" (as identified by the stepping ID in WCPUID) and will not do too much over stock speed. I agree with Tyranos in that you should not have to increase the Vcore for stock speed.

Thanks for your prompt replies. If i can add some more observations:

re: the Sticker - don't recall seeing one when i installed.

There is a switch on the mobo which was default to on and 100mhz. With this as std the machine is solid at std volts for the cpu but is reported by the bios as a 1500+ xp ???

So: cpuid print with switch to off or "auto" gives me:

Internal Clock : 1808.38 MHz
System Bus : 267.91 MHz DDR
System Clock : 133.95 MHz
Multiplier : 13.5

But it won't run unless +5% cpu core volts and cpu temp is then 46-50 C

With the switch on 100mhz the cpu is reported by the bios in POST as 1500+ and cpuid gives me this:

[ WCPUID Version 3.1a (c) 1996-2002 By H.Oda! ]

Name String : AMD Athlon(tm) XP 1500+

Internal Clock : 1363.42 MHz
System Bus : 201.99 MHz DDR
System Clock : 100.99 MHz
Multiplier : 13.5

This is rock solid with std volts but seems slow mhz wise?? - i new the AMD's clock lower than the "advertisements" but thought 1800 was where i ought to be with my 2200+..

I have read some posts regarding psu's and AMD using the 5v rail more than intel? Easytune reports my 5v rail as 4.89v does this seem low?

Any thoughts gratefully received...

Thanks again

erger WELCOME TO OVERCLOCKERS

[Tyranos]

What does it do when you have it at normal speeds (1.8ghz) and you have vcore at default?

[DaddyB]

MOst boards are shipped set to 100FSB to support Durons, they run at 100FSB and if the board shipped set to 133 and somone popped a 100FSB duron in it would be overclocked and possibly unstable or could even burn out.

Your chip should run at 133FSB by default, setting it to auto is fine. It should be stable at 133x13.5 with the default voltage of 1.75V. Your temps are OK for running at stock speed (and even with the extra voltage you should be OK at those temps), some people have their chips running over 60c idle at stock speed/voltage. It's only when you are overclocked that temps in excess of 50c become a real issue.

That said you should not need the extra voltage to run at stock speeds. What exactly happens when you are at stock speed and voltage? You say the chip won't run, does that mean it wont even post?

[erger]

With the board on auto and the volts as auto it "loops" b4 windows starts to load. No bios splash - it does light my monitor up off "standby" though.

If i up the core volts +5% it runs fine and reports the numbers as my previous post ie: 1808mhz or similar - standard as i would hope.

One thought i have had is if my power supply is poor? I have 3 HD's and two opticals. I may strip out all bar the boot drive and see if that helps.

Thanks for your input everyone - its good to have a response to fairly mundane questions.

You should try your cpu in another system and see what happens. If it still needs the extra voltage, rma it. If it doesn't, you should look at your motherboard and try a different cpu in it.
