P3 1ghz Stepping

[BaLa]

I have a Dell Precision 420 Workstation with a single
Dell P3 1ghz SECC2 Proc....
I would like to add a 2nd proc to this machine...
I e-mailed Dell and asked them if the proc needed to be special or something


this is the response I got

Tim,
The Precision 420 was validated with PIII Coppermine CPU's. This
class of processor has an 256 meg L2 cache with external speed
of 133 megahertz (MHz). To add a second cpu, they need to also
be the same speed and stepping.

BTW I used a fake name

he made a mistake 256kb (NOT MEG)

I understand everything he said except for "stepping"
wtf is stepping....and how do I find out what it is....
Here's where I will (most likely) be purchasing the proc from...

http://www.accessmicro.com/productin...d=CPPINS11G100

this says nothing about stepping at all....

[Joe]

first of all do you have a dual cpu board?

[BaLa]

yes I do
I know all the details already, I was just confused about the stepping part....

[BaLa]

this is EXACTLY what I have except for mine has W98SE

Im not sure but I think stepping just means your second cpu has to match the first one.

[Qwijib0]

Each processor goes through several revisions during it's lifetime. This is the stepping of the processor. Because each stepping of processor is slightly different, you need the EXACT same stepping for SMP to work correctly. Use this intel utility to determine the stepping of yours, so you can oreder another exact duplicate. the stepping info is under the "cpuid" tab.

[BaLa]

how do I go about ordering me one of those....I know thru wcpuid
my proc stepping id =6

[Qwijib0]

My best guess would involve calling several retailers and asking about specific stepping.

[BaLa]

damn hardwork
ok thanks....

[Qwijib0]

GOOD NEWS!!!!

Intel publishes a quick reference guide . Match the specs you need with an Intel part number for easy shopping!

[BaLa]

cool....
thanks again

now if I only understood this...

PENTIUM ® III PROCESSOR SPECIFICATION UPDATE
Pentium® III Processor Identification and Package Information

SL4BS cC0 0686h 1B GHz/133 256
Steppings ECC/Non-ECC Proc Sub Rev Package and Rev.
N/A ECC C SECC2


that would mean....the S-Spec is the Intel Part Number?

in this Case SL4BS

[Qwijib0]

That code (in your case SL4BS) is printed on the front of the chip. Since many of the online retailers (or even frys) don't sell boxed processors, it should be easy for them to take a look at the chip they're going to sell you, and read to the info off of it. It's similar to the AMD'ers asking for AXIA's, you just want a SL4BS.

[glc1]

SL4BS = a core stepping of cC0

[BaLa]

I double checked it on my chip
it does say SL4BS on the top.....so thanks again Qwijibo......

now all I need to do is e-mail a few retailers and make sure they have the SL4BS and then I'm set, to throw my money out the window....
