Next I tested the processor in my Asus P3B-F ver 1.4 but I found that it POSTS and then a few seconds later the display turns off and the LED on the display turns orange. (Ie. no signal)
I just have a generic S370 slotket.
Could that be the cause of the issue?
I’ve set the multipler to 6.5 and the bus to 133 on the dip switches.
Has anyone got this adapter working with their Asus P3B-F?

Can you post a photo of your slotket ? It is possibly not supporting FCPGA cpu's.

It’s possible the voltage regulator on the motherboard doesn’t support the required voltage. There’s a thread here on vogons somewhere that lists the compatible ones.

Edit:

Found it:

Chips that can provide voltages down to 1.3V:
HIP6019BCB
HIP6020ACB
HIP6004CB
HIP6004BCB
US3007CW
Chips that can only provide voltages down to 1.8V:
HIP6019CB
HIP6004ACB

Link to thread: Asus ASUS P3B-F (Tualatin?)

Edit 2: You need a Coppermine capable slotket.

Asus P3B-F ver 1.4 supports 1.3v and up.

I would definitely try it out at 100 FSB first, as the 440BX chipset doesn't have proper AGP divider for 133, and depending on the clock generator, it might not have for the PCI either ...

Multiplier doesn't matter what you set on the motherboard, it's utterly locked in the cpu

I checked again, the board version is 1.03. My mistake, I was at work when I posted and got the version wrong.

The slotket supports Coppermine and I have an 850MHz in there clocked at 1130Mhz with 133FSB.

Here are the pics of the slotket and the voltage regulator.

I did try 100FSB but it behaved the same.

The HIP6020ACB supports voltages down to 1.3V.
Also, I have the same P3B-F v 1.03 motherboard and it works fine with modified Tualatin CPUs (manually modified, I never used the Korean guy's adapters) on MSI 6905 ver 2 / ver 2.3 slotkets. Since you have a generic slotket, your mileage may vary.
For what it's worth, I'm using this modified BIOS with my P3B-F, so you can try it out if you haven't already.

That sounds promising. You could try to set the FSB jumpers on the slotket to AUTO and maybe increase the voltage on the motherboard a bit.

I have all dip switches on my P3B-F’s set to auto. I have 2 running with 1.4GHz Tualatin’s. So make sure the slotket is configured for coppermine and leave the other settings up to the BIOS.

Maybe I made a mistake with the soldering of the adapter.

Does anyone have experience with that?

I’m not sure the reset pin AJ3 is making connection because the pin was removed prior to soldering the adapter and I had to fill the hole afterwards.
Would the processor POST without connection?

Should I remove the VID2 pin?

Man, that so called "easy adapter" is much more complicated than simply modding the thing manually. Don't know why you guys bother with it.
byte_76, I have to say, those solder joints don't look too good. So it's very hard to say if the connections are good or not.

I tested the solder connections with my multimeter and they’re all making connection.

I think the lower quality image makes the solder look bad but the solder joints aren’t bad.
I’m more concerned about the connection to the VttPWRGD (CPU side,AK4) pin and whether VID2 should be removed or not.

Yes, it works in my Gigabyte socket 370 board but maybe it’s more tolerant of issues.
There is something strange.
It reports 1.552V for vcore.

That may mean that the korean adapter is modded to signal for 1.55volt. My suggestion is to follow riplin's earlier suggestion and set the slotket to AUTO and set the P3BF to JUMPERLESS via the JEN jumper. If that does not work then there may be something unhealty going on with the slotket or with the power delivery of the P3BF.
That slotket, btw, is a knock off of the "Super Slocket-III" wich on its turn was derived from the Maxtium CPU370 ver. 1.0.

According to his documentation, depending on which pin you connect to ground, it should be either 1.45 or 1.5V.

Maybe the voltage reporting of the Gigabyte board is off ?

Could be... Either way, even if @byte_76 made a mistake when soldering and it's indeed running at 1.55V, it's totally fine.

Per Intel's datasheet:
