P2B and new celeron

[sasa]

I currently have P2B and celery 566*850. I would like to plug in new celeron (1000-1100), but I am not sure will it work on my MB? I have MSI adapter with voltage regulator. Anyone tried this combo? If so, I believe OC will work ok too?

Why not try it and find out firsthand?

[sasa]

Hmmm. I hate the idea to buy something just to establish it wouldnt even work...

My *guess* is that it works. If you have an own voltage regulator on the MSI-slotket, you should be fine.
You don`t get any guarantee of course ...

I'm still cynical about voltage regulators on slotkets... I've heard many people talking about them, but never seen a confirmation from the website of the manufacturer or from some engineer who knows what he's talking about (no offence to others)...

maybe slotkets allow you to set the voltage through jumpers, but that's far from having a voltage regulator on the card... they only tell the motherboard what it should set the Vcc at, but can't work around the limitations of what the mobo can actually deliver. Actually, it you wouldn't overclock your cpu and thus not need to raise your vcc voltage (well... the only other reason I can think of to rais the vcc is when your mobo can't provide enough amps at the vcc your cpu runs at by default), you wouldn't need to set the vcc jumpers/dipswitches at anything different from default.

If anyone can point me at a slotket of which they are 100% sure that it has a voltage regulator, then please tell me... that would mean that I can run a celeron-2 66Mhz cpu on my very old mobo with EX chipset (cut-down LX chipset).

the only rumours about slotkets with voltage regulators I've heard about was one by soltek, which never was actually brought onto the market (though they did have a page on their site for the product.... so they were more or less almost ready to release it I guess).

anyway... if they would exist, how would they guarantee proper voltages? would it request something like 2.0v VCC from the mobo, which almost any mobo would be able to provide? wouldn't the extra components for the voltage regulator increase the costs for the slotket significantly?

anyway, if there's no slotket on the marketplace with a real voltage regulator, I might be interested to build one myself (mod an existing slotket.... shouldn't be too difficult I guess).

The first thing I would check is if the P2B supports the 10-11 multiplier that you will need to run the chip.

I know I have had a problem with an ABIT board which didn't support the 9.5 multiplier. So the Celeron II 633 I was going to run in it didn't work.

The other thing is make sure it is a Celeron II not one of the Celeron IIIs that Intel are making as they will not work at all unless the Motherboard specifically states it supports them (Tualatin processors).

the reason that didn't work probably was due to the BIOS not having the microcode for the Celeron-2 (or not being able to supply the right voltage), since the multiplier is locked on the cpu... it doesn't matter what the mobo supports or not... you're not able to change it anyway.

[MatthewW]

Well, the board had the latest bios update, and the highest multiplier I could set in the Bios was 9. So the machine wouldn't boot as the Celeron 633 needs a 9.5 multiplier. The machine is happily running a Celeron II 566 @ 850.

dZeus, a lot of motherboards wouldn't boot if the MB multiplier was set differently than the CPU's multiplier. I can't explain it, but I know it happened a lot.

[dZeus]

ok... if you say so I believe you

it's just that I hadn't heard about this before.... maybe it has something to do with overclock protection in some BIOSes? I can change a setting in my BIOS called 'speed error hold' which will prevent the pc from booting when the CPU is set at any speed other than it's rated one.

[Greebe]

I have and even when speed error hold is disabled on a BH6 if the multiplier is set incorrectly the machine will hang.

[MK]

Yep, I can confirm that too. Some boards seem to be a little bit stubborn when a slotket is used with the wrong multiplier.

Talking about multiplier, P2B has jumpers for that. Anyway, as far as I remeber, a year ago when I bought celeron 566 the highest multiplier setting was insuficient for celery. He works ok anyway. Friend of mine have 633 celery in same MB. My guess is that new celery will work (not tualatin core) but I was wondering if someone tried it.

I've found a slotket with onboard VRM.... and they claim to be the only slotket with one

Powerleap makes them:

I'm going to order one soon, and upgrade my linux box with 440EX chipset to the fastest 66Mhz Celeron-2

Update: forget it... those things are more expensive than upgrading my motherboard to one that does support the right voltage

i've got one the older msi 6163 boards which was not supposed to support coppermine, but after reading at overclockers.com that many said that most unsupported bx boards would run fine with a slotket. so i got a celery 600 and asus slotket and no prob. i run the slotket at default and do adjustments in bios. multipliers up to 9. shows voltages from 1.7 to 2.0. 900mhz is ok by me.

putting my old 300a to bed was a strangely sad moment though.
