How to adjust VCORE when using Slocket

[Clevor]

When you use a Slocket, it allows you to set VCORE settings even higher than your MB will support. So how is this done? You set your motherboard to a real high setting above what you are shooting for (like maybe 2.00 volts), then set the Slocket to 1.90 or something?

But most MBs will only do 1.85, so do you set it to that in the BIOS and the slocket can bump it up above that via it's own jumpers?

I am trying to get an Asus P3C-E board (820 chipset) with RDRAM to work on an 600E with an Iwill Slocket II. This cCO chip should be able to do at least 133 FSB. I set the slocket to 1.75 volts for starters, as I want to hit at least 133 FSB, but in the BIOS, I can only go up to 1.60 volts, which is where it says I am running now. So far I can only get to 116 FSB.

And I guess the MB will tell me the VCORE is 1.60 (what it sees as it's max), but the slocket may actually be pumping out 1.75? And I presume the only way to check this is to install an OS and check using WPUID, or SISMark Sandra?

Right now I have no OS installed so I'm in the dark.

I know any slotket I ever set to higher than default voltage always ran the chip at that voltage.....it just told the mobo that whatever voltage I had selected was the default voltage for that chip. But your mobo shouldn't give you any more voltage that it's rated for....even if you run 110 through that slotket.

Cw823, so what you're saying is if the MB only goes up to 1.85 and you set the slocket to 1.75, it will run the chip at that and tell the MB that's what it's running at (in the BIOS).

But if you set the slocket to 1.90 the highest the chip will run is 1.85?

I thought somebody on the forum said with the slocket you can set higher VCOREs than the MB? I don't see how, though. It would need an extra power connection somewhere, plus the board itself can't take it.

I need to flash the BIOS of the board to the latest 1023. Right now it's the 1010. Maybe that's why I can only set 1.60 max in the BIOS. That would certainly explain why I can only hit 116 FSB now. That's not bad if I am running .05 volt under the default 1.65!

Hmm as far as I know slotket voltages are usually set to automatically which get a voltage from the vidpinning.

And you can adjust the voltage from the bios thats it.

And if you change the voltage around on the slotket the chip probably won't boot up at least it didn't for me !

I think what's going on is the slockets were designed in the day when you couldn't adjust vcores from the BIOS; you had to do it with jumpers on the board or something.

So if your board will only do 1.85 max, you set the jumpers on the slocket to 1.85 (or higher). Then you change the vcore in the BIOS.

This makes sense to me.

Slotkets were actually designed to run PPGA and FCPGA chips on Slot 1 boards. Many older slot 1 boards had default voltage preset to 2.0v with no adjustment as most slot 1 chips ran at 2.0v. The voltage ajustment on the slotket was to allow for use of new chips and also to allow for overclocking on a mobo without voltage adjustment and with preset FSB increments.

I have an old gigabyte slotket for slot1 to PPGA with voltage adjustment from 1.3 to 2.5v

Actually, most of the slot 1 boards can provide at least 2.8 volts as the original Klamath P2's were built on a .35 micron process and needed 2.8 volts vcore. This includes the BH6 and BX6 boards. All of the slot 1 boards should be able to supply at least 2.05 volts as that was the vcore for the P3 600 Katmai chips. I know that this Soyo board I'm running can supply at least 2.1 volts vcore because I had set the jumpers on my Abit slotket 3 to 1.9 volts and the Soyo board will let you raise the voltage by 10% in bios. The jumpers on my slotket are acting like vid pinning the proc on a FCPGA cpu.

[Clevor]

Yeah Deez, you are right. I remember when the Pentium IIIs came out back in 1998 you couldn't use certain BX motherboards because they couldn't supply voltage low enough for the newer chips. As time went on, the chips required less and less voltage.

So you can use the Slocket to drop voltage down, and a jumper to enable 133 FSB with the newer chips.

So all is clear now. I set the jumpers on the Slocket to the highest voltage my board allows, and change the VCORE through the BIOS.

[Clevor]

OK OK, now I know what you guys are saying. I went home and set the Iwill Slocket to 1.65, and when I boot, I notice I got voltage settings in the BIOS from 1.65 to 1.95! Wow! It's because this P3C-E board is for a Slot 1 and can do voltage well above 2.0.

So if you use a Slocket on a board that can inherently do over 2.0 volts, you can reach that. Pretty nifty since most modern boards will not do over 1.85 without voltage mods.

I set the board to 800 mhz/133 FSB and this 600E boots at default 1.65 volts! And my temp is 27 C. Man, these PentiumIII chips run cool! I was setting up an XP1600 system earlier and my temps were 44C on an Iwill KK266-R and 35 C on an A7V133. Heck, I'm only 2 degrees over my MB temp (I got a PAL 6035 cooler and a 120 mm fan blowing on the board).

Don't know how stable it is since I don't have an OS installed, but should go higher. Only problem is my BIOS will only go to 130, than 133 FSB. But I can go up to 180 in jumper mode, so I'll have to resort to that.

Heck, this 820 board with RDRAM should be faster than my current system, an 800 Thunderbird, since that is running on a 100 FSB (A7V board is limiting me). I know it's a dated board but I never got around to getting it up and running till now (I gotta RMA both the KK266-R and A7V133 board).

I guess I just lucked onto my sit. I have an asus p2b-f and I just plugged the slocket in and started to fiddle with the slocket voltage settings. Whatever I did on the slocket was reflected in the bios. I never looked into it cause...well....gift horse and that whole thing. Couple other posts lead me to believe that the sloket takes what it needs and runs it through. Board manual says that voltage is taken from the vid directly to the onboard controller which I assume is hooked with the slokot. The way I see it, that's the function of the adapter. To assume the needs of the chip chosen. Anyway, it works. Good luck.
