Hi all,

I have an AMD Athlon 1000 MHz processor.
I have a PC Chips M810 series v 5.0 motherboard with integrated Sis 630/730 graphics card and Sis 7018 sound card, and 256MB SDRAM, 40 GB HDD.
The mother FSB claim to be 200/266 MHz

When i set my CPU PnP Setup Page in BIOS to
CPU Speed 1000 MHz
CPU Ratio 7.5x
CPU Frequency 133 MHz
DRAM Frequency 133 MHz

and run Windows 98 SE. the system freezes after some time.

But when i underclock my processor with
CPU Speed 750 MHz
CPU Ratio 7.5x
CPU Frequency 100 MHz
DRAM Frequency 100 MHz

The system runs fine without any problems.
Can anyone tell me how to run my processor at the highest performance level with the current hardware.

Regards
Abhishek

make sure the CPU is being cooled properly. It sounds like it may be overheating.

thanks eddaweaver for your reply.
but i encounter the system freezing up within a few mins of starting of my pc or invoking some processor intesive application. But the system runs fine with the lower CPU frequency configuration.

yes, that is consistant with an undercooled CPU. Intensive applications make the CPU produce more heat, and running a CPU at a lower frequency decreases heat production.

Make sure the CPU fan is running, and the heatsink is attached properly. Has the heatsink been removed and reattached lately?

thanks again for ur reply.
What should be the range of CPU temperature for the same specification.
My BIOS reports tempeatures in the range of 46-52 degree celcius.

I dont recall removing & reattaching the heat sink lately. I dont think so i have removed/reattached it from the processor before.

Hi abhi_ban, and Welcome to the AMD Forum!

If that 52°C is when it's idling, then it's likely too hot when under load.
Use SpeedFan from http://www.almico.com/speedfan.php' ">http://www.almico.com/speedfan.php for temperature and voltage info.
On the PCChips M810L, any version, Temp1 is always your System Temp, and Temp2 is your CPU Temp.
Temp3 is an unconnected sensor, and gives a 'bogus' reading.
This 'assignment' varies from mobo to mobo... compare SpeedFan's values with what's in your CMOS... your CMOS always tells 'the truth'

Try pulling one side off of your case, and just set up a small desk fan blowing cool air directly into the box.
See if that helps to extend the length of time before the system freezes, and please let us know what you find out.
If that helps, then you'll immediately KNOW that it's a heat related problem, and now it's just a question of 'Which component?', and 'What can we do about it?'.
This is the 'quick & cheap & dirty way' to find out if something is getting too hot.
But it WORKS like a charm!

There are many easy, and inexpensive, ways to cool things down, if that's what's needed, and I believe that it is.

Here is my new PCChips M848A' ">http://img.photobucket.com/alb...2_T-2-3-3-6-2_M848.jpg v2.1, with a 1700+ @ 2411 MHz, and my trusty old PCChips M810L' ">http://members.lycos.co.uk/mmm...00MHz_Sandra_tests.jpg v7.1A, with a Barton 2500+ @ over 3500+. Some of my fancy cars are on this pag

also check your heatsink for dust, dust is insulating, it stops the heatsink from cooling right.
