Overclocking a P166, help!

[Guest]

I don't know much about overclocking but I want to give my p166 a little more juice and i know it's clockable. I couldn't find my manual since the move. It's a TritonII board M-8500TUC-A Ver 1. The motherboard manual is at http://biostarusa.com/museum/Motherboards/8500TUC/85tuc_manualt.htm. I understand you have to do something with the jumpers? What jumpers do i need to mess with and how do i do this phyiscally? Anything else I should do. If anyone has any information or can guide me with this please respond, thanks!

There may be more jumper setting available than the ones listed on this page, which is located at
http://www.biostar-usa.com/museum/Motherboards/8500TUC/85tuc_manualt.htm
Make sure you get the address right next time.
If there are any listing screenprinted on the motherboard for 75 or 83 mhz bus speeds you should try them first. Otherwise, try following the jumper settings on the online manaul to get 200MHz out of it. If that doesn't work, set it back and be happy with what you have.
If you really want to go fast, get a K6-2 400, set it to the P55C voltage setting, and the jumpers to 2x (133MHz). The K6-2 will interpret that to mean 6x. Bios will probably say 133, but a clock testing program like wcpuid will show that it is, in reality, runing at 400MHz.

the manual is at
<A HREF="http://www.biostar-usa.com/museum/Motherboards/8500TUC/85tuc_manualt.htm" target="_new">http://www.biostar-usa.com/museum/Motherboards/8500TUC/85tuc_manualt.htm</A>
and it appeares that all you need to adjust is jumper 4 and jumper 7 depending on what speed you want.

I have had my 166 sys o/ced to 188 with no probs, It gets a bit unstable at 200 though

Someone was helping me online and told me to make jp4 open/close and jp7 open close open open open. The manufacturer doesn't have both pins covered in the second pin of jp4, just one pin covered and the rest hangin on. Now I don't know if that is why I get the dump screens when i boot up winnt or not. Does he have the layout of what pins to switch right? It showed 180mhz i think instead of 166 but crashes shortly after that. The manual is at http://www.biostar-usa.com/museum/Motherboards/8500TUC/85tuc_manualt.htm.

oops sorry all for posting that 3 times. crashman i cant get a k6-2 on this board it only allows pentium, cyrix, and k5

 

[Crashman]

That' what I trying to tell you-you CAN use the K6-2, not OFFICIALY but some of us have been playing around and knows what works. I have an AST behind me that only supports Intel processors OFFICIALY but has a K6-2 380 running 400.9 MHz for the past week with no problems. It is a trick that some of us "in the know" have done. It works with any Socket 7 board that supports the P55C processor, aka the Pentium MMX. Stock voltage for the P55C is 3.3v/2.8v and for the K6-2 is 3.3v/2.2v, but the excess voltage is known to not be enough to damage the CPU if proper cooling is employed-on the system I have behind me I have used a generic oversized Celeron cooler. So yes, you can use the K6-2. It will show up in Bios as something different, but a test program will show what it really is. At 2x multiplier with the K6-2 400, your Bios thinks 133 but your CPU runs 400! This is true and can be varified by other members, or look at my previous post here:
http://forumz.tomshardware.com/hardware/modules.php?name=Forums&file=viewtopic&p=626963#626963
BTW-Windows 95 had a glitch with AMD CPU's over 300MHz, the patch is avialable at amd's website and MUST be installed BEFORE going 300 or over if you are using windows 95!

you could but it would be slightly out of spec.
get a 350 or faster.
set jumper 6, 9, and 15 per intel p55c/ct.
close jumper 14.
jumper 4= 1&2 closed, 3&4 open
jumper 7= 1&2 closed, 3&4 open
you will get 400 mhz
to stick with the proccessor that you have
leave the jumpers 6, 9, and 15 at the original etting
jumper 4= 1&2 open, 3&4 closed
jumper 7= 1&2 open, 3&4 closed
you will get 180

jumper 4= 1&2 closed, 3&4 open
jumper 7= 1&2 open, 3&4 closed
you will get 200

if you have trouble booting remove jumper 14

jumper 4= 1&2 closed, 3&4 open
jumper 7= 1&2 open, 3&4 closed

jumper 4 is 4 pin, 2 sets, jumper 7 has 5sets, which ones would ii close if you mean 1&2 open, 3&4 closed

 

[Guest]

when i said closed that meant that those two pins were jumpered together
follow this link to see how the pins are numbered

also the patch for win95 for all k6 over 350 is called amdk6upd.exe you can get it here <A HREF="http://www.amd.com/products/cpg/k623d/win95_update_k6.html" target="_new">http://www.amd.com/products/cpg/k623d/win95_update_k6.html</A>

Tempre with some jumpers, i got my 166 to 200 with a switch of a jumper with the original HSF, but my board burned after serveral month, DAMN SOYO! SOYO SUCK!
