Your point on the new steppings is?

For overclockers, this stepping chart could be quite useful, and in general for people who want to get the C stepping CPU's.

That's the point of my question, what is the purpose of posting the C1 chart if we or him do not know what is different? There could be many having the same OCability, and posting it like this would make no use, unless specified why.

Ya, but I presume this is simply for people who are looking for a particular stepping.

Correct. very usefull for people about to buy a P4.

Are you really that clueless when it comes to "new stepping"? or you just jerking my chain?

The new P4 cores are superior to older NorthwoodB cores. Higher Mhz @ lower vcore/temps.

People are reporting over 3.3Ghz OC on air with the new core @ 1.6x vcore.

You are limited to what your mind can perceive.
August 28, 2002 7:15:15 PM

How come higher MHZ at lower Vcore? The latest 2.8 is higher than the previous Vcore.

Dude, you did not specify the damn difference between the old stepping and the new one, how is someone gonna get a clue to why are you posting this?
If the C stepping has lower Vcore, then explain the 2.8's Vcore.

Ok, so you are clueless my bad.

My example of <A HREF="http://service.madonion.com/compare?2k1=4301626" target="_new">3.33Ghz @ 1.61v</A> This clock speed let alone very low vcore at that speed is a major plus for overclockers.

I will dig up changes in the new core design and post a link. I do not want to state something incorrect as you guys would just love to jump my [-peep-] over anything. hence your reply to this thread.

Untill then, enjoy the stepping chart.

Eden, the steppings are for people who <b>do actually know</b> what all the various steppings are. In other words, it's a reference for people who need it.

The steppings chart is not meant to explain what the purpose of each stepping is. To get that answer, you would have to ask a serious guru or experienced OC'er about that. All I can tell you is that the C steppings are better. They OC a bit better, and they are supposed to take more of a beating (in terms of durability, voltage, and OCing).

The 2.4B and 2.63B with new C1 stepping will start shipping August 30. The 2.66B and 2.8B are both born as C1 steppings. All the rest, 1.8A and upwards, will only start shipping on October 4.

A 2.0A with C1 stepping (SL6GQ) could be very interesting together with PC2700 DDR RAM. At 166 MHz FSB it would be running 3.3GHz.

A 2.2A with C1 stepping (SL6GR) could be very interesting together with RDRAM. At 150 MHz FSB and it would also be running 3.3GHz and PC1200. :tongue:

August 28, 2002 8:34:27 PM

THANK YOU, that was all I needed. If Fugger was smart enough to include what the new steppings help in such as better OCability, I'd say some people like me, would have known why he posted the chart.

Eden, it reminds me of the old saying about cost.

Err, you have too many old sayings Slvr!

I'd be all over these chips if we get some new reports from hardware review websites, and it reveals the majority can attain these scores.

hehe, glad I could help. Fugger might provide some links to explain the steppings. I could dig some up, if Fugger doesn't.

Well that's ok, we know the basic of it, the C1's OC better and should have less power requirements and draw.

The C stepping has shown in several tests of the 2.8 Ghz to gain more than simply the appropriate increase in performance for abotu a 10% increase in speed over the 2.53.

If ignorance is bliss, then why is everyone so miserable?

Im currently running a IT7 MAX w/Media XP again, the P4T533 died in less than a week at stock speeds.

I would post the only benchmark I was able to complete but madonion is down currently.

Does this chart comr from intel or others website

At the end i have speak with a horny lady
August 30, 2002 5:19:44 PM

Both, that list is from the available products list of 8/2002

Several sites including Intel has that information listed.

Pulled some benches at 3.4Ghz.

<A HREF="http://service.madonion.com/compare?pcm=613805" target="_new">#3 Intel P4 on PCMark</A>

I passed a P4T533 3.4Ghz, notice the machine below mine. Now look at the memory scores. he even has a faster FSB.

Quick compare for those who do not know how to use the orb.

<A HREF="http://fugger.netfirms.com/8393.jpg" target="_new">DDR vs RDR RIM4200</A> @ PCMark2002

PCMark cannot determine the Mhz worth a crap, 170x20 = 3.4Ghz

I have look at spec finder and specfication update only P4 2.8 have C1 stepping are the part i have look is not update yet i will be happy if you can give my a link.

At the end i have speak with a horny lady
August 30, 2002 11:51:25 PM

Thanx FUGGER....some usefull info...i copy and pasted ur chart into a notepad document, and if i ever build a P4 system for me or anyoen else Ill remember which stepping to get =)

This CPU owns hardcore, 3.3Ghz full time.

I took #1 Spot on 3Dmark2001 Unlimited tonight. I maxed the orb <A HREF="http://service.madonion.com/compare?2k1=4342039" target="_new">over 20k</A>.

R9700 is a sweet card. They got the drivers correct with the release for once. OpenGL and D3D are both top notch so far.

August 31, 2002 3:52:14 AM

Wow, that's a really nice system you got there. I wonder what the 3d marks are for that system that was OC'ed to 3.9Ghz. It was C1 stepping, p4 2.8, running stable at 3.9 with LN2. They got it to POST at 4.3, too.

August 31, 2002 4:13:40 AM

That is a different class of scoring, I run a stressfull benchmark at a high Mhz, not boot into the OS and take a SS.

LN2 is not good for extended periods of time. I can run 24/7 at top speed. My fricken vcore is like 1.575

And the lamest catagory is where you use a camera and take a pic of posted Mhz on screen.

You are limited to what your mind can perceive.
August 31, 2002 4:34:16 PM

Agreed....but we also all know the reason why they do that is because the system didnt prove to be stable in Windows so they took a SS to show what they could clock it at and have it post......

August 31, 2002 6:00:15 PM

Wow, nice score Fug. You say well into 20k....how high did you get it?

This sig runs too hot.
August 31, 2002 7:41:29 PM

Intel and ATI making the top score in 3DMark2001! If you'd told that to people a year ago, they'd laugh at you! WOW, times have changed! :lol: 

Intelligence is not merely the wealth of knowledge but the sum of perception, wisdom, and knowledge.
August 31, 2002 8:52:47 PM

I know, but I'm just interested in seeing the benches for that 3.9 system. They probably had their vcore at like 1.75 or something. I agree, your system is stable, because your voltage is at a good level.

August 31, 2002 9:08:06 PM

Kamu is benching at 3.9Ghz today, he just posted a new #1 in default with a Ti4600. Should be knocked down soon with a R9700.

Eden, I am the first to max the orb (non-bug/cheat). This was done in the "unlimited catagory" against LN2, phase change, dry ice... I posted a short list of cooling I use.

Best of all my system is a 24/7 system and the ATI quality has not been crapped out like you can do on the GF4 to get high score. I am still at 3.310Ghz

August 31, 2002 10:41:29 PM

What was the stock clock for your P4?
If it was 2.8GHZ, I'd be rather disappointed, because 500MHZ using such cooling is pretty sad IMO for an OC. I am sure you can get higher, but I wanna know first the stock clock before judging for sure.

Im using a 2.66 @ 3.31Ghz on a unmodded IT7 board.

But that is not important right now, this is...

<A HREF="http://www.xtremesystems.org/forums/attachment.php?s=&p..." target="_new">Oppainter's 2.66</A> on Promtheia phase change. 3.4Ghz on default vcore of 1.525

I will update my bios and mod my board. pure stock these things rock. I will get a PR rating from Sandra benchamrk. good for a laugh or two.

August 31, 2002 11:34:11 PM

Yes but don't you think it can go further than 3.3GHZ?

very impressive... would like to crunch some cure for cancer with that.

but i wonder whats the max speed one can stabilly get with just simple aircooling... say the mcx4000 or the big alpha aircooler?

<b>My CPU cooler is so Massive it bends Space and Time! :eek:  </b>
September 1, 2002 4:05:02 AM

Hey, for that kind of voltage, that's an impressive clock speed. It can go farther, but <i>may</i> require more cooling depending on how far it's pushed.

September 1, 2002 5:10:50 AM

If it's on the same voltage then yes it is impressive, but if it starts to go higher to say, 1.65V, I disagree.

Oppainter is somewhere near 3.7Ghz now. Not sure about his vcore. but pulling 3.4Ghz on default vcore shows how much breathing room Intel has in this core. I may hit 4Ghz by years end.

September 2, 2002 12:57:07 AM

But aren't you using some refridgeration unit? As Eden said, try using only air cooling if you've got the time. I'd like to see how well it can do.
