Tualatin in P2B 1.10

Hi all,

I have a Tualatin SL6BY on the above board. I'm using a Lin Lin adapter -> slotket into the motherboard.

At first it wouldn't post, but with the latest bios it is, and with jumpers set, I'm getting 1399mhz and it boots, however, I get a warning with a hardware error saying there's an error on the Vcore, and it's running at 1.5v.

I confirmed the board has a voltage regulator that can handle the lower voltages required, is the error being thrown because it's not typical? Or is there something else afoot? Just trying to figure out if I should be concerned at all. I was hoping to set it to 1.45V and the Lin Lin is jumpered that way, I think, but it's still giving 1.5v, but I'm not exactly sure of the Lin Lin/Slotket interaction.

The slotket is a Super Slotket III, for reference.

Any help would be great.

EDIT:

From what I can see, my slotket has no jumper settings that affect voltage, it's basically all Auto or chosing the FSB/Intel or Cyrix and dual or single CPU. So for whatever reason 1.5v not 1.45 is being request by the Slotket. I'm not sure how the Lin Lin adapter affects this all.

Sorry for the double post.

Been fiddling with this a bit. The motherboard does respond to the voltage changes requested by the Lin Lin. If I set it to 1.4v, it recognises that. If I set it to 1.55v it reads as 1.6v, so it seems like the motherboard can't read or possibly rounds up voltages in-between .1 of voltages, which I suppose makes sense? It seems like it works fine either way.

Could anyone with a P2B verify if their Vcore can read to the 0.01? It's gotten my curiosity!

I actually have a P2B in one of my retro systems and could take a look this evening.

That class of motherboard comes with a voltage regulator configuration that fully supports 'in between' voltages - see attached.
My guess is that the Lin-Lin and the slotket don't work together properly by design or maybe some of the pins don't make good contact.

Hmm. When I transplant the CPU directly into my BH6 it seems to work correctly with the correctly reported voltages. Although that tries to let you select the voltage yourself.

On my bios screen, the Vcore is only reported to the first decimal place, whereas other voltages are reported to the second. Screenshots I've seen of other P2B bios screens don't look like mine, so it's hard to compare.

Seems like it could be something to do with the bios, and the way it reads the voltages.

See speedfan attachment. It goes from around 1.44v to 1.47v at highest.

I appreciate this isn't probably of much interest to anyone, but I've found out so many things by searching 'oddly specific retro hardware issue - Vogons' that maybe it'll help someone in the future 😀
