That's a PPGA Celeron only slotket I'm afraid.

Celeron only? It supports the copperming p3 cpu for sure, since it has the bus 133 mhz selection.

The slocket pictured has no VRM onboard, so it relies on the mainboard to provide the appropriate power to the CPU. Some BX-based boards can provide low voltages, so the best thing you can do is check the PWM-chip located near the SLOT and Google the datasheet to see how low it can really go.

This slocket simply tells the mainboard how much V to provide, and it's up to the PWM to deliver that. If the PWM can't deliver the required power, the system will (at best) not start.

Other more advanced Slockets (Powerleap etc) have voltage regulators on board, and they disregard the mainboards CPU power circuitry. that allows you to run a Tualatin on practically all Slot 1-boards (and the whole reason they're nigh extinct.

edit: Tualatins also have some pin alterations, so you'll have to mod this slocket as well as see to the V requirements.

That is not necessarily true.
The 66/100/133 fsb selection affects just the bus speed.
The difference between a slotket that only supports Mendocino Celeron versus a slotket that supports Coppermine core cpu's is that the pin wiring is different.
There are a lot of recipes for modification on the web. Here is one (in german) that describes the modification that the Gigabyte GA-6R7 Rev 1.7 needs for Coppermine support (second paragraph from top).

Thank you very much for the clarification, it seems I was short sighted seeing all those voltage support on the back, it's pretty useless

I think it was one of the last revisions before Gigabyte launched their Coppermine supporting slotkets. Your slotket has a time mark indicating week 49 of 1999. Around the same time or shortly after the "Pro" and the "+" versions hit the market.
