99FF85AF-848D-4123-A2C0-AAF657C02EE5.png updated the picture guide (OP, feel free to fix my mspaint skills lol) In other news I found a plastic 233 tillamook. Also, If a 4.5x multi exists…. What setting would that be? Bf2 pulled low? Edit: I’ve been working on a device to solder to the back of the …

Oh yeah, this is relevant to a thread I started the other day. https://www.vogons.org/viewtopic.php?p=1054063#p1054063 Follow it, I’m hoping to eventually have a pcb that can be soldered to the back of the motherboard with a bunch of tricks built in to solve problems like this. I am not familiar …

One of my boxes is similar, please let me couple of comments: +1 for adding forced cooling of a Voodo3 PCI. After some uptime they really become unstable or start displaying artifacts w/o any overclocking. And it would be a pity to damage such card keeping in mind their current prises. ASUS 430TX …

There is quite a lot of discussion about adhesives going on in the k6 2+ To 3+ Mod thread. For that you probably want a epoxy. A moisture cure would never harden to the center. https://www.vogons.org/viewtopic.php?f=46&t=85071&p=1053903#p1053903 Or as others have said, clean it up and get a new …

Can you return it to the way it was and see if it still works? If not, you should get it fixed before trying again. Can’t chase more than one issue

You'll need separate pull up and pull down resistors per pin. The diagram you show is effectively shorting all three BFx pins, making all have the same level Oh okay, so the pull up resistors should be on each line? Good catch. Thanks. I’m ashamed to say I missed that lol it’s so obvious. …

I’m curious, about something… The 233mmx supported 2x-3.5x But Later on the tillamook intel thought to put the bf2 pin here: (shown is the 233mmx p55c not tillamook diagram) ABBE305E-6967-4B60-95EF-7C1EA5232543.jpeg The tillamook supports multipliers up to 4.5x It’s possible that intel had planned …

ilembitov on discord just used the guide to do this to a pentium mmx :-) and says it’s working. It appears they are pulling bf1 to ground which should be relatively safe, but a higher ohm resistor may have been another approach that may have safety benefits. (The kingston used 25-ohm, the intel doc …
