Yes, but not all processors can be overclcoked.  keep this in mind.

I have got email from people that have overclocked PB Hillary, PB 600, PB 640, PB 680.  I am sure there are others, but I just need some one to tell me.
 

That decision is yours, there are some risks.  Most people have no problems, but there is the occasional horror story.
 

Simply change the jumpers or dip switches on your motherboard to the next higher setting.  For example a 120 MHz would be set to 133.  If it does not boot, then you may have one of those CPUs made by Intel that can not be overclcoked.
 

Try one of my system pages, if I wrote a page on your system it should have the jumper locations on it.  You can also try you motherboard manual, if you don't have one go here.

That's ok, just visit this page to find out your system type or if you are lucky the jumper setting are printed right on the motherboard, if you can read them.

If it boots, is a good start.  If the system does not boot, forget about Overclocking.  Also they system must remain stable, run it for a time.  If you keep getting crashing, that was not normal before then you either need to keep the chip cooler, or forget about Overclocking.

Also I would recommend running a benchmark on your system, like Wintune.  This way you will know if the gains you get are worth it.  for example Overclocking a Pentium 133 to 150 is not enough gain, this is due to the lower bus speed.
 

Please read the following Overclocking links, they will explain the theory behind Overclocking much better then I can.  I learned everything I know from these pages.
• Intel FAQ
• Info on Overclocking (Speed-Margining)
• The Overclocking Guide - One of the best sites on the net
• Overclocking the Final Frontier!

No.  Intel has tried hard to make it so certain cpu's can not be overclocked.  They disable something inside the cpu to prevent it from being overcloked.  This disabled jumper is usually connected to the Multiplier frequency and those CPU's can still be overclocked if you use a higher bus speed.  However PB computers do not have 75MHz or 83 MHz bus speed needed to do this.

Some time intel will sell a higher processor as a lower one, the most recent example is the PII 300 production is ahead of demand so intel is rumored to be selling them as PII 266.  This makes these chips perfect candidates for overcloking.

In addition to the P133, the P200MMX and P233MMX are not overclockable, at least the newest ones.  I read that the earlier CPU's can be overclocked.

While I was writing this page I got the following email:  "...if a motherboard will support 66 mhz (like the pb600) the 180mhz overdrive will run at 200 mhz. it seems the 180mhz is obtain on a 60mhz bus. the overdrive is clocked at 3 and you cant change that but you can change the bus speed... cause it reads the bus speed then x 3 whatever it is.. of course this is Overclocking and he didn't condone this but I am sure the processor would work okay." -  Joe

I have not confirmed this, but it gives you something to think about.

Also, my boss has been running the Evergreen MxPro 180 at 200 MHz with absolutly no problems.  However another individual said he tried it and it worked for a week and then they system started crashing, he immeadiatly set the speed back to 180 and has had no problem since.
 

No, it is like tuning up your car to make it go faster.  Of course you go too fast and get caught you will get a ticket.  With overcooking your system will crash or your processor will burn out.

Of course if you sell the overclocked chip as the higher processor then it is illegal.  This has happened many times.  Shady computer dealers will sell P166 that are really P150.  Some of them would even go so far as remarking the chips.
 

Simply because of the number of questions I get on the subject, this web site grows by the email I get.  If I get too many questions on a particular subject I will make a page on it.

Also I wish I had a chip I could overclock, unfortunately my P133 is not very overclockable, read my experiment at overclocking my PB 640.

You bet, any experimenting with your system like this is not recommended and PB will not cover it if you screw up your system.

my official answer is, don't overclock.

I would unofficially say it is best to overclock when you were thinking of a major upgrade.  For example someone with a P75 that wants more speed, but is looking at $400 to upgrade to where he wants to be.  For a little more he could basically have anew system.

I would say a person in that situation could try Overclocking, it might get them by until prices fall for an upgrade and if something happens the price of a new motherboard and/or CPU is a price he was willing to pay anyway.

Or when you are willing to take the risk.  I can not emphasize this enough, I do not need anyone coming back to me and say "it's all your fault".  No it is not, it's your computer and I told you not to do it.

There are some product that will let you have higher multiplier settings, such as the powerleap adapter.  Read my CPU upgrade page for, more details.

The heat is caused by overclcoking and it is this heat that could cause your chip to fail.  You need to keep your system cool.  Start by getting a good fan to put on the processor, many of the processors that are 133 Mhz or less do not come with a fan on the processor.

Other ways to cool are to run with the case open, or to install more fans that blow air into or out of your case.  You should also make sure you have a good heatsink on your processor.

Get a hold of a program like CPU Idle, Waterfall, or Rain all three of these utilities are designed to keep the processor cool through a special instruction set in the CPU.  See my PB Tool Page for links where you can download these.

Also if you have a PowerLeap Plus the contraol panel will monitor the CPU temperature for you and warn you if things get too hot.

Just send them to me by visiting my contact me page.
