PC reboots when FSB is increased !!!!

[Anthropy]

Hi
I recently bought a new Jetway Motherboard and an Athlon AMD 2.6.xp
The RAM is 500mb DDR 400 and is new. The power supply is 450w.
Everything is fine if I set the FSB to 133MHz (default) but when I
increase it to 166MHz the PC reboots when I run a demanding program
i.e game, video editing etc. The CPU temperature is about 50c and the
system 40c.
Am I supposed to do something in the BIOS after I've changed the
hardware FSB jumper?(the current setting is "optimum") There's nothing
in the manual about it.
Thanks for any help or ideas.

What's the temp of the video card GPU?

neighbours from crime, and became the victim of it. To jump to the end
of the story, as a result of this I need a bone marrow transplant. Many

What's the temp of the video card GPU?

My video card is a Geforce 440. I don't know how to get a temperature
reading from it. There's nothing in the software.
My PC uses DDR 400 Ram and the video card SDRAM. Could that be the
cause of anything?
Thanks

What's the board's full number/revision?
Also are you trying to Over clock?

The system temp is high. Is that the temp at idle or at load? Try running
with the case opened and see if the temps go down and/or rebooting problem
stops. If it does, you need better ventilation.

Well, is it a 266 or a 333 FSB 2600+ XP?

Nah, and old card like that shouldn't be overheating unless its fan has
died, assuming it has a fan.

That never hurts.

Did they even make any Thoroughbred (133/266) 2600+ CPUs?

Well, if they didn't then there's some sellers who're going to have a heck
of a time providing what they're advertising.

https://www.prismblue.com/shopping/product_details.php?id=270 is one.

I'm not sure. how do I find out?

Hi, thanks for the help.
The chip was sold to me as a an AMD Athlon 2,6 xp. CPUz (chip
diagnostic prog) says it's more like 2.
The board name is Jetway V2MDMP, 500mb DDR 400, H/D (80g)
and the manual lists this CPU as compatible and I am not overclocking.
At the point when the PC reboots the temperature is about 50c (CPU)
and 40c (board) so I don't think overheating is an issue.
I've had the FSB set at 133 for a couple of days running very
intensive software and no problems. Could it be a fault in the CPU?
Thanks again for any suggestions or ideas

No it isn't.

It's winter. 40c is warmer than any system I've had,
including my old t-bird which idled at 54c. 40c is not too hot, but it
indicates to me that either the OP has poor ventilation, the case is in a
stuffy, poorly ventilated area or he/she has a high ambient wintertime
temperature in their house. Considering the OP has symptoms that can be
caused by heat, I think it's worth taking a look at.

Hi, thanks for the help.

2600 isn't the MHz of the processor, it's a 'rating' and the nomenclature
is XP 2600+, with a PLUS sign (consider the + sign a 'tip' that it isn't MHz).

Near as I can tell a 266 FSB XP 2600+ should be running 2.133Ghz.

A 333 FSB 2600+ would be running 2.083GHz IF it were on a 333 FSB. With the
266 (133 MHz) you're having to run to be stable it would be 1667GHz and
that isn't anywhere close to your 'more like 2' number. So, off hand, I'd
say you have a 266 FSB XP2600+ and the 'more like' number is probably 2.133Ghz.

As to your previous post asking how you can tell, it's written on the
processor package.

Jetway isn't known for quality.They are best known for low price. That said,
there are a few things you can try. If possible,set the BIOS to default or
failsafe setting.Then, raise the vdimm voltage in the BIOS by .1v at a
time.Also,try changing the CAS setting in the BIOS memory settings. Try 2.5 or
even 3.0. Go to this website for everything about BIOS settings.

That's the clock speed, which has little to do with the 2600+ rating,
which is how it compares to intel processors in terms of performance.

What we're talking about here is that there were two Athlon XP 2600+ CPU
types released with different cores. One with an FSB of 133, and another
with an FSB of 166. If you have one designed to be used at 133, that
could be part of your problem! Though I would expect the heat to be
significantly higher at 166 if that were the case.

I have never seen the processor package as I had the dealer install
the CPU, it was a deal, board and chip (hangs head in shame) and I'm
quite new to all this. After hearing so many horror stories concerning
slipped screwdrivers it seemed the sane thing to do.
Is there any other way to correctly determine the CPU's FSB ? I have
run diagnostic progs but I'm sure they produce info based on the
current settings in the BIOS, not the integrity of the CPU. If I'm
wrong please tell me.
Thanks again and happy new year to all

Thanks again. I obviously need some education regarding CPU's. Can you
recommend a site or knowledge base?. I know I could Google the
subject and get millions of hits but maybe you or anyone else could
point me in the direction of a tried and trusted knowledge base
bearing in mind I'm relatively new to the internal workings of PC's..
Thanks and happy new year.

Here are the results of CPUz.

AMD Athlon XP

Code name: Thoroughbred
Socket A
Technology: 0.13u
Voltage: 1.632v
Family 6. Model 8. Stepping 1.
Ext family 7. Ext Model 8. Revision B0

Clocks

Core speed: 1662.8 MHz
Multiplier: x12.5
FSB: 133.0 MHz
Bus speed 266 MHz.

I'm not sure if this info pertains to the integrity of the CPU or is
merely a list of the BIOS settings..
Thanks for any help.
