Some slockets have voltage jumpers - are these just to instruct the motherboard or do they have regulators on them? - most seem to have 1.8v as the lowest voltage

There is only one slotket brand that comes with a Coppermine supporting regulator on board and that is Powerleap.
They come in two flavours:
PL-iP3 for Coppermine
PL-iP3/T for Tualatin & Coppermine
The 'T' version is relatively rare, one is currently on offer on the famous 'e' site for $300.
The other slotkets that have on board voltage jumpers are indeed just instructing the motherboard. If your board does not go below 1.8v than that is as low as you can get. There are a number of slotkets with jumpers that start around 1.4v. but I have seen quite a few reports on this forum and elsewhere about running Coppermines at 1.8v.

This was my main rig from 1999-2001. Mine also didn't support Coppermines. (I found out the hard way. I had to return an upgrade CPU because it wouldn't work.)

Mine ended its life as an audio/video capture machine running Windows 2000 with a 1.4 GHz Celeron (on a PL-iP3/T), 768 MB RAM, a Matrox G450eTV video capture card, and a Sound Blaster Audigy 2 ZS connected to the Hi-Fi system via the breakout box.

Nope, unless you mod the voltage regulator you're limited to P2 Klamath and Deschutes, P3 Katmai and Celeron Covington and Mendocino.

The fastest CPU at stock speed will be the P3-600 (non-E, non-B). None of those CPUs overclock much beyond 600MHz, but you may be able to run a P3-600B at native 133MHz if the motherboard can handle it and your VGA is OK with 88MHz AGP speeds.

Was the upgrade cpu via a slocket or an actual slot 1 cpu?

I was looking at this modification which seems to make coppermine possible on slockets with this board (assuming you up date the bios to ones new enough to support)

It was a 550E Slot 1 Coppermine and simply wouldn't work. I wound up getting a 500 Katmai, later a 600, which was the fastest CPU officially supported. (I emailed the OEM company asking this.) This was before I got the Tualatin Celeron and adaptor.

No it won't.

This is a PPGA to FC-PGA mod for a PPGA Celeron slocket to let it use FC-PGA Pentium 3 and Celeron CPUs. It doesn't change anything about the voltage options on the board. so won't help getting Coppermines to work.

Yes, realise this wont change the voltage, but looks like needed to make coppermine CPUs work in general - both coppermine based celerons and P3s?
Realise would still have a slight over-volt but from the looks of posts before, 1.8-2v on a coppermine is doable.

Yes, it may be 'doable'. You can find references everywhere including here in Vogons threads.
But the title of your thread is: "Slot 1 ms 6119 440bx cpu advice".
And that is what you got in this thread and earlier in:
MSI MS 6119 440BX board and coppermine Pentium 3?
When you ask for tips to build a kludge that will run high-end cpu's out of spec on a board with a 16 Amp VRM that was designed for a lower class of less power hungry cpu's you will likely get different answers.

No, not in general. It has nothing to do with the motherboard but is only needed on an old PPGA slocket. If you have a FC-PGA slocket it is not needed and Coppermine So370 CPUs can work (just like Coppermine Slot 1 CPUs) on a motherboard which supports their voltage. Like yours doesn't.

So FWIW for future forum searchers -

Got a coppermine 1.1GHz 100fsb 1.75v CPU working well in a slocket on this board.

I got a slocket with voltage jumpers so could manually set (as my board doesnt have a voltage regulator that can go below 1.8v) and set the jumpers to 1.8v
Didnt get POST and had -- on POST card
So went on to modify the slocket following http://krick.3feetunder.com/370mod/
However, rather than try to remove the AM2 pin from the socket or cutting it off the CPU, a wrapped a very small peice of sellotape around the CPU's AM2 pin to isolate it.

Then got POST but wouldnt get to the second POST screen after RAM test etc where gives system summary and starts to boot. Tried disabling cache, tried overvolting a bit to 1.85v - no dice.
However, overclocking the FSB to 112 MHz solved it and it POSTed and booted. Seems stable - able to run half-life, quake etc without stability issues so far.

Cool, better bookmark that, that was the mod I was trying to find for my M748LMRT, which are socket/slot boards where coppermine works in the slot but not the socket, because it's PPGA.
