CPU UPGRADE

By azizhakim ·
IN ATTEMPT TO FURTHER MY KNOWLEDGE IN PC HARDWARE I UNDERTOOK THIS PROJECT.I UPGRADED
MY PC WITH AN ASUS P5-A MOTHERBOARD W/AMD K6-2 CPU(333MHZ)THING WENT WELL.I DECIDED TO PURCHASE A FASTER CPU.GOT AN AMD K6-2(450MHZ)
REPLACED THE CPU .RESET THE JUMPERS AS ILLUSTRATED IN THE BOARD DOCUMENTATION(THIS WAS MY FIRST TIME WITH JUMPERS).THE PREVIOUS SETTINGS WERE 66.8MHz W/MULTIPLE OF 5.0 TO GIVE IT 334MHz CPU SPEED.I SET IT FOR 100MHz
W/MUTIPLE OF 4.5 TO GIVE IT IT'S 450 MHz EXTERNAL SPEED,HERE IS THE PROBLEM.I WAS TOLD
THE MAXIMUM INTERNAL SPEED IS 95 MHz.THE DOCUMENTATION DOES NOT GIVE ME THE CPU TO BUS
FREQUENCY MULTIPLE OF 95MHz TO TOTAL THE 450MHz CPU SPEED.I SEE THE SPEED DURING POST,@450MHz,BUT DO NOT NOTICE ANY CHANGE IN PERFORMANCE.IS THERE A WAY TO FIND THE INTERNAL SPEED TO SEE IF I INSTALLED THE JUMPERS CORRECTLY.I HAVE WINNT AS MY OS.AFTER
I UPGRADED TO 450MHz,WINNT EVEN ASKED ME FOR
MORE VIRTUAL RAM WHICH I CHANGED FROM 64MB TO
110 MB(THE MAXIMUM ALLOWED TO ME) I CURRENTLY HAVE 64 MB-PHY

Try using iCOMP 3.0 (Intel Comparative Microprossor Performance) and perform a benchmark test. www.intel.com

I use a program called sandra for looking at that stuff. The other place you can look is on the initial bios splash...shouls say K6-2 450 bear the top.

Couple of things you may wan tto try though

If you got 100mhz Ram, make sure you have the jumper set to use the PCI Bus instead of the AGP, If it's an older stick, you'll want to leave it on the AGP bus.

There's one jumper for a higher voltage with a warning in the manual saying that this is et if you're overclocking. Granted you aren't now, but it sounded like were before, so make sure you have that set back to the default. These are the only two things that aren't covered in the diagrams for setting all the jumpers

If this is your first time with NT, it will seem like it's running slower. NT doesn't have all the little graphics accelerators and things like that as 95/98 does.

Good luck to you

Mark

First off disreguard this statement from the previous answer:
If you got 100mhz Ram, make sure you
have the jumper set to use the PCI Bus
instead of the AGP, If it's an older
stick, you'll want to leave it on the
AGP bus.
The AGP BUS is for an Advanced Graphics Array or in simpler terms a higher performance video card. You main performance issue is with the amount of memory you have. You stated that you only have 64M of memory. Upgrading the processor by about 100 Mhz without adding more memory is only going to boost performance by about 10% (not enough to actually see). Since you were running a bus speed off 66Mhz it is probably safe to say that the memory speed is the same 66Mhz.
Changing it to 100Mhz and adding more will increase your performance noticably.

An AMD K6-2/333 will run on PC-66 ram a K6-2/450 needs PC-100 ram. I have also been able to get a K6-2/333 to over clock to 350 MHZ with no problem. you can go here for the exact jumper settings you need for your ASUS P5A. The Url is: http://www.bigedtech.com/bigedtech.com-new/html/mb/asus/socket7/p5a.htm
I hope this helps out if you need any more help or info feel free to contact me.

For information about your hardware I strongly recommend SiSoft Sandra 2000. Even the demo version will provide you any info you need. Even if it's designed for Win 9x, it also works under NT.
If the splash screen after POST diplays 450 Mhz, then 450 it is.
Now the bad news. One year ago I was in the same situation you're facing right now. I upgraded from a K6-2/333 to a K6-2/450 and the performance gain was so low that I got mad and bought an Intel based system (Celeron 400). I noticedthat the benchmarks indicated a 95% performance gain compared to the K6-2/450 system. Do not forget that the K6 based systems are a low end solution.
