hey guys! got a new 2.4B with C1 stepping (pics of it at 3.1 with 1.7V)

thats right i got a new 2.4B with C1 stepping!

cpu info:

BX80532pe2400SL6EF

and my version is:

C10670-001 Pack date 09/25/02

FPO/BATCH# 3231A416

i used (the forum is down so you have to copy paste it<sorry>

and here is the retail box with the info

ohh and it runs at 25C idle.. sisoft is correct checked the BIOS and it says 25C and the probe says 24C

That's a pretty low CPU temp, my 1.8A OC'd @2.1 runs @30C idle. BTW, can I have your old CPU?

janusz · Oct 17, 2002, 10:31 PM

well winters helping and the watercooling.. plus the low voltage on the cpu..

my old cpu is in a grave. it suffered SNDS
Sudden Northwood Death Syndrome
: its were if you run the cpu over 1.85volts it will start to cook itself no matter how cold.

RIP my 2.26B@3.2 everyone take a moment for silence

Wow, sweet OC. 700MHz is alot

Anyone know that the main changes are with the C1 stepping? Just curious as a C1 P4 2.53 arrived on my desk this morning

nice job janusz, its about time Abit starting giving you alot more free hardware though

It's with out a doubt much better for overclocking: http://www.vr-zone.com/guides/Intel/Northwood/

But acording to overclockers.com, they have raised the core voltage to 1.525V from 1.5V and optimzed the 0.13 micron core, so it will be more stable and allow better overclocking. Also they expect that C1 stepping will be used to almost 4 gHz, so it seems to be a very stable and overclockable core.

But there is more!!

Geek News repports that if you underclock a C1 stepping CPU to the same speed as an "old" P4 CPU, it will run faster, since they fixed a bug in the core (this one: http://www.theinquirer.net/?article=5184 ). AnandTech reports that it runs 2% faster then the "old" CPU with the same speed!!

Or as HardOCP explains about the C1 stepping:
(a) they get higher quality higher speed processors from the production; (b) remove bugs and; (c) obtain a higher ‘yield’. (Yield is sort of like planting 10 seeds and getting 10 plants instead of 8.)

Phew that's all for tonight

Thanks

Yeah but did anyone notice that in the bench mark it didnt do so well against the 2.6 ?(im assuming you did the benchmark overclocked right ?)

Erroneus · Oct 22, 2002, 07:06 PM

What benchmark is that? But if the CPU is overclocked, the fsb is set higher then normal and this will effect result....

That sounds so cool.
