When I tried to run a CPU like that (FCPGA) on some slot 1 boards using a slocket, it wouldn't run. But my boards are all early pentium 2/3, and I think they don't support 133MHz FSB. If yours does, you can try it.

It's possible that SquallStrife's socket 370 1GHz Coppermine is a 100 MHz bus version. How do "budget" slotket adapters work? Do they rely upon the mobo's CPU voltage circuitry to power them, or do they have their own VRM?

Nah, it's a 133MHz FSB model, says so right there on the wafer! 😀

Theres a chance it simply may not work? It may also depend on the motherboard.
Btw, I think doing from 667Mhz to 1Ghz is a good improvement 😀

I wonder if the slocket you used was designed for Tualatin and it wasn't giving enough voltage for the coppermine processor (1.45 for tualatin, 1.7ish for Coppermine). Some slockets seem to have VRM's built into them.

Of course its always possible that the BIOS and chipset simply don't support that CPU even with the slocket. Back in the day I tried to upgrade my aging Pentium 2 266MHz with 440LX chipset to a 766MHz Celeron (Coppermine). Even with the slocket the system wouldn't boot. Thankfully I got the celeron for free since someone was throwing out their system, and I returned the slocket to the shop. If only I'd waited a few months for the 440BX and 100MHz FSB P2's to come out I would probably have been able to upgrade up to 1.3GHz without problems 😒

In my case, I think it's pretty sure it has to do also with the slocket. It's very simple( I suppose a VRM would have some sort of extra circuits, right?) and I think it's written Pentium II on it.

Interesting replies, cheers guys!

The motherboard is an Asus P3V-4X, and the current CPU is a Slot1 Pentium 3 667MHz, 133 FSB, 256KB, 1.67v.

Based on that, I think that maybe the current CPU is probably a Slot1 Coppermine? So a "passive" Skt370 to Slot1 slocket should be enough to get it working, yeah?

If it won't work, my guess is that the high end slot 1 Coppermines (at least the 133Mhz fsb ones) are cheap these days.

Well, no more need to wonder!

Try clearing the CMOS, remove the mobo's coin battery, and unplugging the mains plug. Then wait for a couple of minutes. Hopefully, it'll be OK. Changing CPUs can very occasionally confuse the BIOS.

Edit: minor typo corrected (Changing)

Yup, mobo's don't die for no reason.
Something must've happened.
Reseating often helps, as does cleaning any contacts.

Do you get any beeps?

Mm, appreciate the help, but I spent a good few hours trying to revive this sucker, reseated everything, cleaned contacts, remove battery, cmos clear jumper, reseated everything again, tried different RAM, different graphics card, ad nauseum.

No beeps, dead as a doornail.

Have to decide whether it's worth buying a Skt370 mobo, or maybe just forget about it and put in one of my Socket A boards...

If you have no s370 board whatsoever, they should be dirt cheap these days. Imo, they can only go up in value and even if not, they will become scarcer with passing time, so you'll get less choice.
s370 is, imo, one of the best Sockets ever made 😀

Yeah, there is a Computer Market every Sunday near where I live, I might get lucky and find something there... Might get super lucky and find some pre-Skt478 gear!

If not, I'm pretty sure I have a SktA board and an Athlon somewhere around here... *rummage*

Recently, I got a socket 370 mobo with 2 ISA slots! It accepts a 1.4 GHz 133 MHz Tualatin server CPU, and seems well built. It's a Soyo 7VBA133U mobo. Perhaps consider this mobo when browsing for retro parts, either at markets or online...
