Hi,

Basically I am repairing a computer for a friend and just recently he has been having frequent reboots & BSOD.

I have tried replacing the hard drive, memory & graphics card, without success.

Yesterday I decided to load fail safe defaults in the BIOS, which changed the FSB to 166 instead of 200. (AMD Athlon XP 3000). Although the chip is now detected as a 1.7GHz instead of 2+Ghz the system is stable and performing brilliantly.

What does this mean – cpu, power supply or motherboard faulty??

Look forward to your replies.

Thanks

Robert
 
I have tried running mem test. All okay!

Even tried new memory!

Would you leave processor at 166FSB if stable - even though it should be 200
 
May be a PSU issue then, got another PSU you can test with? Or can you test all of the hardware in another PC?

Found this about the AMD XP Athlon on good'old wikipedia.

Specifications:
Barton (130 nm)

L1-Cache: 64 + 64 KiB (Data + Instructions)
L2-Cache: 512 KiB, fullspeed
MMX, 3DNow!, SSE
Socket A (EV6)
Front side bus: 166/200 MHz (333/400 MT/s)
VCore: 1.65 V
First release: February 10, 2003
Clockrate: 1833 - 2333 MHz (2500+ to 3200+)
166 MHz FSB: 1833 - 2333 MHz (2500+ to 3200+)
200 MHz FSB: 2100, 2200 MHz (3000+, 3200+)

3000+ appears to be 200 fsb, as standard.

is his cpu definately the 3000+?
could be a 2500+ or 3200+ overclocked, and you are positive its not overclocked? I would say if you reverted back to defaults and its changed the fsb, its a sign it has been OC'd.

If it has been OC'd could be ram n cpu speeds not in sync etc.

:)
 
3000 should have an fsb of 200 mhz.

I suspect either his ram is DDR333 (in which case it can only do 166 mhz) or you need to re-do the thermal gunk on the cpu.
 
How can i check what the actual CPU is without taking out the CPU. Any software?

Can putting more paste on the CPU solve this issue?

Should i replace the power supply?

Thanks everyone for your help so far.

If its overheating then its a possibility, not TOO much though, thin layer.

Test it before.

Np ;)
 
Here is the processor details from CPU-Z

Name: AMD Athlon XP
Code Name: Barton
Technology: 0.13 um
Voltage: 1.648 v

Spec: AMD Athlon(tm)
Family: 6
Model: A
Stepping: 0
Ext. Family: 7
Ext. Model: A

Clocks
Core Speed: 1746.9 MHz
Multiplier: x10.5
Bus Spped: 166.4 MHz
Rated FSB: 332.7 MHz


Is this a 3000 chip. Or is the 166 correct for this type of processor?
 
What motherboard are you running this on and what version?

Some NVIDIA socket A motherboards boasted they could run at 200 Mhz (400MHz effective) but the truth was that only the "Ultra 400” (revision 2) fully supported synchronous operation with AMD’s 200MHz FSB speeds such as the 3000 and the 3200. I simple BIOS update won’t do the trick either.

So it maybe that the chip was running under clocked before you touched it.

It’s also worth noting that PC3200 memory requires at least 2.7 volts to operate at 400 MHz.. so check you have this set correctly.


as far as I remember there were two flavours of this chip. All Barton cores came with a default FSB of 166MHz. The 3200 came out much later and was the first to have a default FSB of 200Mhz. The 3000 (200Mhz) came out later as the Barton was dying out iirc.

there you go.. read the above post... Look inside.. It will have the revision stamped on the motherboard... 1.0, 1.1, 1.2 or 2.0

Only 2.0 will run this chip at 200MHz FSB at default.

Post back what you find...
 
Hi,

Its a rev 2.00

- Is it worth changing power supply.

- CPU runs at 60 c - is it worth putting more paste on.

- What else to try or leave at 166

Did you not read my post above? Try testing the PSU in another system, or the system on another PSU.

That is abit hot for a CPU, reseat the CPU clean the paste of and reapply.

Why don't you try it and find out?

Glad it's the 2.0 :)


as Jaffa Cake said it's a little too hot but this wouldn't cause the system to BSOD.. it would just cut out when it reaches a certain "fail safe" limit.

Try re-seating your CPU with some Artic Silver 5 (You only need a very small amount on the die, size of a grain of rice). Clean off the old stuff first.

As for the voltages, Asus have a good Voltage history monitoring tool which will tell you if your voltages are stable or not..

Allow for some deviation. For 5volts between +4.8volts and +5.2volts and for 12volts between +11.5volts and 12.6volts.



Anything outside these there is certain to be a problem with the power supply.

Have you checked the memory voltage as per my previous post?
