Hi everyone,its my first step in overclocking and its not a succesfull day!!

i bought a system with a Pentium-s 133mhz and i want to overclock it so i go to the bios (AMI) and i can't find anything to help in this way.

No fsb available ......nothing!!!!

so i go to the dip switch on the motherboard,i make every possibility and the result gave me nothing good.

i just go down on megahertz like 90 or 100 or 120!!!
finally i put it back to 133 mhz.

i am so disappointed nothing to do maybe i done something wrong!

i saw on the motherboard the table for dip switch and when i put higher the multiplicater like 3x its put my cpu to 100 mhz!!!

really i don't understand!!!!

please help me to push this thing faster i am dying on windows xp

by the way its not so terrible with xp and 64 mb

thanks bye

there is nothing in the bios on an old machine. all jumpers and dips. 66mhz FSB? Try 2.5 mult. for a 166

Hmmm...there was a certain batch of P133 chips that was locked. I remember hearing about it. Can't remember if it was like SY033 or something like that or SY022. I dunno. My P133 runs at a 3.0x multiplier and 66FSB at stock voltage (no voltage tweaking on this baord) without problem...

Did a little research and found this...

Quote from Tom's Hardware Guide
In case you want to overclock a Pentium 133, try to avoid the 'SY022'. 33% of the Pentium 133 with this S-spec have been disabled for multiplier settings of more than x2. In my database there are 22 of 66 entries with the 'SY022', where the CPU wouldn't support multipliers of x2.5 and x3. A small number of SU073 also seem to suffer from the same problem.
If you have an SY022 P133, it is, most likely, locked. I read somewhere else just a few moments ago that said most P133 and P200MMX chips were locked. :(

thank you duronoverclock,its seems like my cpu is one of them.

maybe im gonna buy an other processor like a 166 mhz....

133MHz was the fastest a lot of motherboards supported. You may simply be at the limit of your mobo. MY P100 was like this- 100MHz was the fastest it would go, so wasn't much I could do...

my mobo can take up to 266 mhz on a pentium and 300 on a amd k6 i think ,i think its my processor who can't go further then 133mhz.

the mobo take 60 or 66 fsb

the multiplier goes to 1.5 to 3.5

the motherboard is a AI5TT baby-at makes by taiwan mycomp co.

My P233MMX was locked. No higher than 3.5x :(. Didn't really matter though because 3x83 was the fastest setting I could probably ahve used. 3.5x75 worked for like 261, but 3x83 for 250 was faster. Damn I loved that setup. Started with some POS Packard Bell that I got for $26 at a computer show. Ended up ruining that board somehow...I think I flashed the wrong BIOS, and then fucked up the bios chip trying to get it out. Then I bought a ASUS SP97-V. Worked awesome...that is, until another corrupted BIOS flash (damn floppies!). For a while, I had no idea what I was gonna do so I bought an ASUS SP97-XV. Basically the SP97-V with USB, and ATX form factor. Then I found this guy named Arthur Keekmeester or something. His site is www.flashbios.org I believe. Can't remember. So for $7USD (plus the $3 it cost to ship overseas back a couple years) I had my chip sent to him and reflashed with a good image, and back to me within a week. He's helped me a couple times with various dead boards I've received from people.

I'm going to be getting rid of my P133 soon I think.. depends if my uncle's P166MMX will work in my board. The Intel board I have doesn't support MMX chips, nor their voltages. So I'm gonna try the chip in the board with good cooling and hope it doesn't fry. I may eventually get around to voltmodding the board down lower as well. If the 166MMX works out for me (need the extra cache for my server), then I will be looking to get rid of the P133 I think...
