Question about Intel Pentium 3 , 450 MHz Pentium III (SL364) Boxed Processor

3 Answers

I accidentally changed my CPU clok frequency from 100 to 250 and now my computer won't boot?

Ok, I tried to 'overclock' my Intel Pentium III Processor like in PC Mag
a while back and now my computer will not boot. I changed the clock frequency instead of the clock speed. When I boot my computer it powers on and the CD drive hums for 2-3 secs and the computer dies down like it is in stand-by.
I have tried booting my Win XP cd to repair Windows XP to try that but my CD drive will not boot anything either. I also tried Fix it Utilities 6 boot cd but it wont boot either. Can someone please help me???

Ok I realize this is old and you may have given up by now or gotten it figured out, but I'm gonna try to help even with that being said, first of all I just recently had the same problem, this is a sure fire way to fix your issue,
step one, open up your computer so that you have access to the motherboard,
step two, find the system battery.
step three, near the battery there should be a jumper, this will be a little plastic piece with metal connectors inside it, it should be slid onto two pins out of three available, move it over one space meaning if its on the left and middle move it to the right pin and middle pin, the three pin pole should say cmos right by it, or clear cmos.
step four remove system battery, no need to worry this is just the memory for the cmos chip and it will revert it back to when the board was new, you can change the settings in your bios program back to what they were when it last worked,
step five, making sure that your power cord is not hooked up to the computer in the back, (no power to computer) press and release your power button a few times, (this will drain the capacitors stored power)
step six, walk away for about 20 minutes, just to make sure that clearing of cmos was a success,
step seven, replace cmos battery.
step eight, move jumper back to original possition.
step nine apply power to the computer and boot up should be operatioinal again, you can then go back into your bios setting and change as wanted, however I would only overclock a little at a time as boards will only handle so much overclocking before they will freeze up, i would not go more than 200 mine froze at 200 so you may not even want to go there, Hope this helps.......

    Don't know what your pc model is but to access the bios you have to hit one of the following keys when the pc is re-booting. Before it makes it to Windows. F1, F2, Del, F10. Like I said, depending on your model. Sometimes there is a message on the bottom of the screen when the pc is booting telling you what key to hit to enter setup.

Installing new cpu on a emachine


According to the specs I have Serena, the eMachines eTower 633i Desktop PC, uses a TriGem Cognac motherboard.

[TriGem is the manufacturer, Cognac is the model.
Note it is Not the TriGem Cognac+ ]

http://www.motherboards.org/mobot/motherboards_d/Trigem/Cognac/

Specifications. (You can click on the photo to enlarge)

PDF motherboard manual,

http://www.elhvb.com/mboards/TriGem/manuals/index.html

Click on - Cognac - in the left side of the list.

Going back to the Motherboards.org page;
(Nothing like upside down photo information, and the motherboard is turned 90 degrees to the Right, to how it actually sits in your computer case )

The processor socket is a Socket 370,

http://en.wikipedia.org/wiki/Socket_370

Used for Intel Pentium III processors, and intel 'Celey' processors.

(Excuse me......Celeron.
An Intel Pentium III processor has TWICE the L2 cache, that a comparable Intel Celeron has.
The cache for a Processor is a small memory area for the Processor.

It is the First memory the Processor accesses.
The Ram Memory is second, and the Harddrive is third.
More cache for a Processor makes it more faster )

The motherboard chipset is an Intel 810.

The Northbridge chip of the motherboard chipset, is an Intel 82810.
The Southbridge chip is an Intel 82801AA, or an Intel 82801AB.
(Intel ICH, or Intel ICH0 )

Looking at the chart, and reading across, you can see what the Intel 810 motherboard chipset supports;

1) Processors: Intel Celeron, or Intel Pentium II, or Intel Pentium III.

2) Processor Front Side Bus: (FSB) 66MegaHertz, or 100MHz.

3) SDR Sdram ram memory at 100Megahertz.

[Single Data Rate Sdram is often just referred to as Sdram.

Erroneous.
Double Data Rate Sdram is also Sdram (DDR Sdram)
Synchronous Dynamic Random Access Memory
So is DDR2 Sdram, and DDR3 Sdram ]

Also referred to as PC100.

So when looking for a CPU you look for;

1) Fits in a Socket 370 processor socket.
Yep. The best is going to be an Intel Pentium III.

2) Has a FSB of 100MHz.

Hmmm,............

http://en.wikipedia.org/wiki/List_of_Intel_Pentium_III_microprocessors#.22Coppermine.22_.28180_nm.29

Scroll down.

Pentium III 1100.

Maximum frequency rate ('Speed') is 1.1GHz (1100MHz)
Front Side Bus = 100MHz
Uses a Socket 370 processor socket.
Part Number = RB80526PY005256
sSpec Number = SL5QW

256MegaByte of L2 cache. (256MB)

A comparable Celeron would have 128MB of L2 cache.

[ Don't forget to follow Anti-Static Precautions.
Clean the bottom of the Heatsink THOROUGHLY, and the top of the Processor if it needs it. (I always do anyway)

PROPERLY apply fresh, new Thermal Paste.

I upgraded the processor of my ibm thinkpad r51 to centrino duo and when i push the power button it won't power up.


I have found that just because a processor will fit in a socket, does not mean it will work. I asume the old processor was working; put it back in and try before doing anything else. One other consideration is: Windows (from 2000 forward) keeps a record of the processor number. If you change processors, Windows will not work, and will start but go the the blue screen. This is a built-in feature to keep you from using your software installation in other computers. If you do not mind reinstalling Windows, along with all your other software and updates, you might double check to make sure 1) the processor is situated correctly in the socket. Most will go in only 1 way; there are some you can get in wrong, and 2) that the new processor is fitting all the way down, all 4 sides. If your computer does start OK with the old processor, this would be a great time to make a backup of your files, along with a written record of which hardware you have and which drivers you will need.

What are the futures of a computer which is described as Pentium 4


Hi,

Pentium 4 refers to the laptop processor.

Intel Pentium 4 is a family of high-performance microprocessors that succeeded Pentium III family. Pentium 4 CPUs are based on new NetBurst micro-architecture, which differed significantly from P6 micro-architecture used in Pentium II/Pentium III microprocessors. As an overall CPU performance is proportional to its frequency and its efficiency, to achieve better performance levels many micro-architectures, including P6, strike a delicate balance between faster CPU frequencies and improved efficiency. The NetBurst microarchitecture used different approach - it attempted to improve performance primarily by increasing CPU frequency, often at at the expense of efficiency. One of key elements in this approach was "Hyper-Pipelined Technology" - 20-stage pipeline (not counting decoder stages), that was significantly longer than in previous generation of Pentium processors.

The rest of the components in the laptop are used in many other laptops. For example hard drive, memory and graphics.

Regards.

How to overclock Intel Pentium Dual Core E2140 1.6 GHz processor


The following link will tell you the very simple way to overclock this processor. Half way down the page you will find the header "OVERCLOCKING"

http://www.value-reviews.com/index.php?page=pentium-dual-core-e2140

"Since the architecture was designed for the 1066 MHz FSB, overclocking is as trivial as setting the FSB to 1066 MHz (266 MHz quad pumped).
...you instantly get a 2132 MHz CPU with little increase in temperature."

Next time you boot, go into your Bios and change the CPU settings back to normal. It's possible you did fry the processor but unless you set it back to normal you'll never know. Best of luck with your problem.

How to overclock a pentume 4 processor


Increasing of FSB (processor clock) from 10% up to 15%.
from 1700Mhz you can get 1850 Mhz.
from 2400 Mhz you can get 2640 Mhz
from 3000 Mhz you can get 3300 Mhz
but not all mater board allow this do.

UpGrade


you could only upgrade the processor and RAM in this condition i.e.

you can only change your an upgraded p-III processor like 1.0 GHz, 1.1 GHz or 1.3GHz and
upgrade the RAM by changing to 256 in each slot.

that is all what u can do with ur pc

OVERCLOCKING


The 800 MHz seems to be your system bus speed and not the CPU speed. They a related but no quite the same. Overclocking is usually defined as forcing something to operate at a higher speed than it was designed to. If you changed the 800 MHz to 1.6 GHz in your BIOS then yes it could be considered overclocking.

One thing I would like to mention is that when changing clock speeds in your BIOS, do it in small steps, if done in large steps it can cause system instability.
