My biggest concern now is the voltage requirement.

I ordered an Intel Tualatin Celeron 1.4GHz(256K) 100MHz FSB 1.5v with On-chip Socket Adapter for Coppermine sockets
https://www.ebay.com/itm/281931957654
the seller lists the Biostar M6TBA as compatible with the right slotket.

Should the MSI MS6905 Master v2 Slotket with VID as low as 1.5v work with this CPU and mobo?

I am concerned about the voltage requirement because I don't know if my Biostar M6TBA Ver. 1.4 is able to work with VID on the Slotket of 1.5v.

I am pretty sure the board it self is from sometime in '99, and it has an award bios update from June 2nd 2000.

MSI MS6905 Master has a good reputation but the version 2 was followed up by three revisions in a short time span. Over time I ran into a couple of reports on instability of version 2 so it may be hit and miss. If I had the choice I would go for version 2.1 or version 2.3 with the latest date stamps.

I don't think it would make difference since my boards regulators can't handle 1.5 volts? I don't know...

Also, I already bought a ver 2.0, but the seller seemed fishy, so it may never show up.

Don't know if you've seen this... https://en.wikipedia.org/wiki/List_of_Intel_P … _III_processors

This lays out all P3 compatible CPUs... Tualatins have more L2 cache which is a big boost. Katmai L2 cache runs at 50% clock speed, whereas Coppermine & Tualatin run at full speed.

Thank you.
I think I have seen this, but yeah. My motherboards voltage regulator is designed for 1.8 to 2.8 volts. LX1664CD

So I may, in a while, get a Celeron Coppermine 1100/128/100/1.75v (close enough to 1.8v shouldn't be a problem)
But the 1.5 volts 1.4Ghz Tualatin might cause issue issues with my voltage regulator?

And if the MSI MS6905 Master V2 shows I'll use that, if not I'll probably go with a generic coppermine Slotket. Do you suppose it would need VID jumpers or should it do fine with a jumperless slotket?

I can't return the Tualatin because of... conditions I won't discuss here... but I won't be able to use it without a Powerleap PL-iP3/T since that has an on board voltage regulator...

-A Tualatin will not live long at 1.8 volts.
-You cannot use a slotket without voltage jumpers because your motherboard will not boot with a cpu with lower voltage than 1.8 volts and the slotket has to be configured to send an 1.8 volt signal so that the motherboard 'thinks' there is an 1.8 volt cpu installed.

You can do it on most boards. It’s just a matter of finding a suitable upgrade for the vcore buck controller chip.
I upgraded it on multiple boards such as the Gigabyte GA-6BXC rev 1.9 and the Amptron PII-3100, and they work great with every chip, including modded Tualatin 1.4 GHz CPUs (even though the Amptron has an older BIOS which doesn’t support the Tualatin at all).

That may be beyond my abilities at the moment, but that is a great idea. I was also told my board uses faulty capacitors that are imminent for failure at any moment. But I will use it up until its end, or maybe save it by replacing the capacitors at a time which I am capable.

In the meantime I will try a Coppermine Celeron 1400/128/100/1.75v with the MSI MS6905 Master v2 if it arrives, or an alternative coppermine slotket with voltage jumpers to at least 1.8v.

It will be a while before I can see if it works because of circumstances.

I did check, no bulging or leaking capacitors yet, and I haven't had any weird graphics or performance issues/crashes.

Do you mean the Tualatin Celeron 1400/128/100/ 1.5 V (not 1.75 V) ? By the voltage mentioned though, I believe you meant Coppermine Celeron SL5QW 1100/128/100 (100x11.0) - 1.75v.

I meant to say the 1100, sorry about that.

Weird this page and whatever chatgpt sourced (which may have been this or a similar page) says 1.8 to 2.8? I wonder what's up with that...

I would guess the link you provided is for LX1664CD which is based on LX1664 but not identical in output.

And the chip on my board is LX1664CD, so it is safe to assume I can't handle a CPU of 1.5v?

Also the spec sheet you sent includes: Regulation Accuracy 1.8V≤VOUT ≤2.8V
