Faster chip for a socket 7 mobo

have a 166 pentium in it now with 128m sdram.

I'd like to have a faster chip.

I tried a 233 pentium which I couldn't get to run faster than 166 because I didn't have the right multiplier in the bios and frankly, it's been too long since I bought this board...
I'm not even sure if I can change the multiplier in the BIOS or if I need to use jumpers.
I've tried everything i can think of and I'm done messing with it.
Hell, I don't even remember what brand this thing is.


Anyway, I'm wondering if there is a chip I can drop in this thing, Intel, AMD, I don't care.
Just something I can drop in where no matter what the multiplier is, I get a good boost in speed.

I don't want to mess with it anymore. I just want to lift the lever, swap chips and lower the lever.
Plug in the new fan.

So what are my options?
 
Old socket7 boards are not jumperless.. you have to determine the chipset to find out if it can take a K6 or just a regular Pentium, also you have to make sure the thing isn't maxed out at what you have.. (it may very well be) there is no way you can just buy a K6 or something and throw it in, and expect it to work... on new boards yes, not on a mobo like that.

order of business:

1. Determine the chipset. ALi Aladdin V for example can take all the way upto K6-2 550 or K6-3 500 if it's an older chipset, might be a P55C max (233 Pentium)

2. Find the jumper settings for sure.. if you find out the thing only takes a max of 233 then you can rest assure it's obviously not an Ali Aladdin chipset and likely will not take anything faster than a 233.

if it's an Ali chipset, you can likely do something about this, but will likely require playing with jumpers still


good luck man 😀
 
I was in that situation....I had a P166 w/ 48 mb EDO ram in win98(It was soooo slow 🙂) , and I was comtemplating upgrading to a P233 or P266, but instead I did the smart thing, and bought a used P2 motherboard and a Voodoo 3 AGP, and put in my old P2 400, 384 PC-100 RAM, 10 gig HD. I only spent $45 on it, and its a rocket in windows 2k
 
There are socket7 convertors u can buy, but I would find out more about your mobo before you try anything more.
 
To get a 233 to work in a board that doesn't have a 3.5 X jumper, set it for 1.5 X. You will need to figure out the jumpers on a socket 7 board.
 
Really old pentium motherboards only have 2 jumpers for clock speed, usually called BF0 and BF1 (names of the pins they connect to on the CPU) yielding 4 combos:

1.5x
2x
2.5x
3x

Pentium MMX and K6 (all variants) treat 1.5x as 3.5x instead, just set the jumpers for 1.5x (which is really 3.5x) to get 233MHz.

In order to support a Pent MMX (there is no such thing as a 233 plain vanilla pentium) the board MUST support separate voltages for core and data bus, which means that it WILL support a K6, no question. It might not support the proper lower core voltages for K6-2 and K6-3 though.

Also, for K6 series there is 3rd jumper, BF2, which if you put the jumper on will switch the possible multipliers from 2x-3.5x to 4x-5.5x If your mobo is missing that 3rd jumper, you will not be able to select a multiplier higher than 3.5x.
 
Yeah, I couldn't figure out the jumpers and I have no documentation.

I do recall that I have the ALI chips.
