Official C1 P4 stepping tracker.....

[RalfHutter]

Here's the actual C1 stepping list from Intel. Happy Holidays!.

Click on this link for the C1 goodness!

 

[TechMasterChen]

Is the C1 chip able to handle higher voltage settings better? What's the actual difference between the two chips?

 

[Duvie]

UPDATED LIST to include 1.8a c1's.....


As far as I know all c1's are starting with a higher vcore 1.525v and therefore obviously may not be able to push as far since I still hear 1.7v should be treated as limit...

how much vcore so far?

Default, or whatever my Asus P4PE decides to give it


I'll be starting a thread about it soon

What about its?
Pentium IV 2.66B GHz C1 Stepping Box
Pentium IV 2.80B GHz C1 Stepping Box

 

[Duvie]

No great surprise there as all 2.6(400) , 2.66(533), and 2.8(533) chips are c1 stepping chips....The real idea behind this thread is for us overclockers (ie cheapscews) to get the best bang for our buck which is likely to come with the 2.4 or less speed chips....

 

[THUGSROOK]

my personal goal is to hit 200fsb.
the 2.26b is only chip thats gonna get there. if the Granite Bay boards end up with "i845pe syndrome" (167fsb max) then ill have to change my gameplan and go for a 2.0A

 

[dbwillis]

2.0a? whys that?

[edit], now I got ya. Thanks Thugs

 

[THUGSROOK]

what would be the point of running a 1.8A @ 167fsb? we can already do that ~ no challenge
the next step would be to get a 2.0A up there

Yeah.. I know, Its just for doing a quick search on google
I still think you should add them to the list.....someone may want one

 

[TenEgg]

hmm...if they want one of those high multiplyer ones, they can just order/buy anywhere....

 

[Duvie]

I talked to atacom and they said they only have c1 stepping 2.4's...Hopefully they will notify me when any other c1's of lower rated come....

I need to talk to googlegear and see if they can guarantee a c1 if one ask for a certain SL code...

Just picked up a C1 1.8, but need to chill my beer before I start on this project. In fact the place I got it from only had C1's across the board. I got if from PC Club in Lynnwood, Washington for those in the area. I will update with my progress...

[godspeedx]

I got a P4 2.5ghz from NewEgg on September 3rd with C1 stepping.

 

[Duvie]

Yourself, does Pc Club have a web page for online orders??? Anyways that is good news as we have a confirmed c1 1.8 siting!!!

 

[Yourself]

Duvie-

It's www.pcclub.com and according to the salesman, they supposedly get some sort of priority when it comes to Intel shipments, hence the C1's. I don't know how much crap that is, but I do know that I inspected close to 10 cpu's from 1.8's to 2.53's and every one was a C1. The down side is that they are all OEM. But, PC Club does have a 1 year warranty on OEM and for most of us enthusiasts, 1 year is plenty

PS-Beer almost chilled, I'm about to sign off and try this chip out.

 

[THUGSROOK]

kinda pricey for oem chips :Q

thx for the link ~ looking forward to your results

 

[caboob]

That's awesome i just live 10 minutes from there!!! will pay a visit.

~$10 more than Mwave or Newegg isn't too bad.

Bad news so far :


Won't pass 1 second of Prime 95 at the following settingswhich is very conservative)

18X155
1.75v


System info:

Albatron PEV Pro
1x512 Corsair 3200c2
Ti4600
blah
blah

I will keep messing...

 

[Jgtdragon]

Oh No.
What S- Code is that chip?
Was hoping goign to 150fsb or above with default voltage. Also what Power supply you using?

 

[Yourself]

SL6LA

Antec 350w PS

I'm pretty sure its not power related as I have a P4 1.6 here that does 165 FSB all day long


Self

 

[Jgtdragon]

What cooling you using? hehe
trying to figure out what is holding you back. Hoping not the cpu.
BTW...what is the highest you can go at default voltage?

 

[Yourself]

Never a slacker on the cooling

Alpha 8942


Highest that seems stable at default is 140 fsb, but still checking.

[caboob]

with these northwoods, the limits seem to be within the CPU rather than heat management short of going to a prometia or vapochill. My watercooling setup for an B0 1.8A improved the operating temperature but did not help me gain anymore speed out of it.
