Upgrading PII->PIII?

I have a Dell PII-350 machine which I would like to upgrade to a PIII-600 (E I think - 100MHz/Slot1/256K)..

I have been able to upgrade my bios to a version that supports PIIIs, but Dell will not say one way or the other wheather a PIII will work in my motherboard (this is a Precision 410 Workstation).

With the same bus speed, connector and bios support, the only problem I can imagine is voltage: Do PIIIs have different voltage requirements from the PII line? Does anyone know if this should work?

Thanks,
bliab

 
PII uses slot 1. PIII uses mainly socket 370, but also a few models are slot 1. your motherboard bios can surely cope with the voltage. even if it couldn't, there are slot 1 to socket 370 converters which have voltage adjustment on them.
 
if your only planing on a 600p3 i'd buy a 566 celII and slocket.then ride the 100 buss.🙂
just make sure your mb will handle that speed.
 

The slot 1 to socket 370 converter sounds interesting, but I cannot locate much information on any with the exception of the Anandtech article on slocket II. Are there any other converters with VRM?

Tho I'm not interested in running dual CPU right now, this is a dual system and the article states that the slocket cannot run dual..


 
get an Asus 370-DL slocket!
this will allow you to use dual cpus in the future should you so require or just the single cpu. the asus is a slocketII & will work satisfactorily, provided your m/board voltage regulator can supply a minimum voltage of 1.8V or less.
 
The PIII slot 1 katmais (eg., 450s) are similar to the PIIs voltage-wise. The PIII cumines (like the 600), need much lower voltage, ie., 1.65V. If your BIOS (or a jumper/dipswitch on the mobo) lets you drop the voltage down that low, then you might be okay...

I have a PIII 600 slot1 and there are still quite a few out there for the 600s, 650s, 700s. In fact, last I heard, intel decided not to drop the slot 1 format yet with the 800s as originally planned, so there's a few of those as well...

If you can't adjust the voltage on the mobo (and considering this is a Dell mobo, that's more than likely), then you would need to get a slocket for a 370 CPU that will let you step the voltage down to 1.65V or so...
 
Ok, does anyone know if these things actually convert voltages or do the Vcore jumpers simply tell the motherboard what voltage to generate?

I've found a few reviews that indicate that voltages are still dependant on the motherboard, and I have been unable to locate any serious documentation (other than jumper settings) on any of these slockets/slotkets (Abit, Iwill, Asus or otherwise)..

They change the voltage to what you set the jumpers on the slocket for. You can also put the slocket on auto and it will set the chip to the default voltage.
