As promised I'm whipping up a quick article on how multiplier
unlock the Pentium II processor.
I'm sorry the photos are so large, but I've only recently re-built
these machines, and I can't find my copy of Photoshop. I
attempted to reduce them, but too much clarity was lost.
This is honestly really really really simple to do, and I know it's
safe, as I've run an unlocked 400Mhz PII @500 for 3+ years
now without a single burp. As you will see later, it works with
other PII processors.
Please read along, read twice, *then* attempt this. While
easy it is, I don't care to be bombed by questions that can
easily be answerd by looking at the photos, and reading my
simple text.
------------------------------------------------------------------------------------
Virst, the victim:
Typical PII 400, slightly modified by a young overclocker known
as The Lonely Raven. While I don't have a kick *** Nikon 950
that takes killer macros, this 3 year old Olympus in my steady
hands does pretty well. You can even read the serial, model,
and batch code!
Note the oversized heat sink and lack of stock fan, typical of
the Compaq computer I pinched it from. If my memory serves
me correctly, I got this from a machine that was struck by
lightening and replaced by insurance. The customer was so
happy with my customer service/technical skills they gave me
what they thought was a useless hunk for "spare parts".
Here we have the mod itself. Just a friggen piece of tape.
This is the same piece of tape that's been key to unlock this
processor for the past 3+ years. The key to the unlock is taking
the processor so the hologram is facing you, and count 11
THICK PINS from the right. If you look at the photo, you will
see thick pins and thins pins. The thin pins actually turn into
thick pins further up the PCB. Just like an AGP video card, two
rows of pins in an over under format.
What I do is cut a sliver of scotch tape thats just about the
size of the thick pin on the processor. It doesn't matter if it
goes over the little pins at all, but don't let it cover any of the
thick pins accept the #11 from the right that is our target!
Simply line up the piece of tape with the pin, press it on as best
as you can, and trim off anything that might roll off the bottom
and onto the other side of the PCB. Remember, only Pin #11!!
Just to retest this "magic tape" unlocking method, I grabbed
a PII 300 processor, unlocked it using above method, and
plugged it into my Dual Slot 1 Server Motherboard. Notice the
clock speed!
Then I thought, Duh! I can run my 400 @ 400 and the 333 @
400 and stop my bitching about how I don't have a matched
pair for this server!! Please excuse the slightly blurry photos,
even my steady hand isn't steady enough for a 1 second
shutter speed needed to shoot a photo in such lighting
conditions...
I'd show you photos of SETI crunching a WU on each processor,
but I didn't realize that I have to completely install windows
again for it to recognize and utalize the second processor.
I figured I'd better get this article up quick before I get lazy and
blow it off for a nice quiet (barring the fans) weekend.
I hope this helps out my new friends and team at
Overclockers.com!
Please ask questions here in this thread, I'll do my best to
answer them when I find time!
Thanx for reading!!
