How to read P4's??

[Kunaak]

I am pretty familiar with how to read a great deal of the code on a AMD CPU, but as of now, I still can't see how people know what thier P4 CPU is.

I know my CPU is a costa rica only cause it says so on the CPU IHS itself.

other then that, heres whats on the box.

Product code: BX80532PG2400DSL6WF

MM: 852314

FPO/Batch: 3318A035

Pack date 6-5-03

so what here in this tells, me anything?
it would help to know, so next time I can look for a malaysia.

"Reading the FPO/BATCH Code on your Intel CPU"

by TASOS

Since there are many new member here in these forums....that cannot really "translate" the fpo\batch of their cpu....here follows a small guide....the more experienced members can correct me if i'm wrong in any of these....thx.

1st letter or digit=plant code
0=San Jose,Costa Rica
3=..............,Costa Rica
1=Cavite,Philippines
R=Manila,Philippines
7=..........,Philippines
9=Penang,Malaysia
Q=...........,Malaysia
L=............,Malaysia
8=Leixlip,Ireland
Y=Leixlip,Ireland
6=Chandler,Arizona

Example:L149A463-0726

L=plant (Malay)

2nd digit=Year of production (2001)

3rd & 4th digits=week (49th week )

(A463)=some kind of traceability number

(0726)=Serialization code

Any more input is welcome
Thanks

FPO/Batch: 3318A035

so from here, thats 3=costa rica, 3-year, 18 is week, rest is blah blah blah (useless)

from here: BX80532PG2400D

would SL6WF be considerd the "stepping"?
is steppings even important in P4s?

[charlie]

SL6WF is the S code
Stepping is C1, D1
S code identifies whether a chip is OEM, RETAIL, voltages and origin.
C

[Kunaak]

I don't really understand what you said there:confused:

[charlie]

S code...I used to have a great link for an S code calculator on Intel website. You enter the s code and it gives you important info. S code is important for Intel oc. But current P4/800's are all on the same s code. I will search for it on Intel.com
C

[AZN]

SL6WF is the sSpec code like charlie said and yes it is very important cuase it will tell you what revision the chip is AKA Core Stepping BO, C1, D1...
the myth about which plant the chip came from is somewhat accurate and sometimes its just luck.

the costa rica week 52 for the sl6rz seem to be the best C1 overclockers for the 2.4b. that chips performed slightly better then the malays but now it seems the malays D1 are performing better then the costa rica. seems to go back and forth so i really dont know what to say but just pray you get lucky.

[charlie]

BOOM! There it is...thanks AZN.
Kunaak, all you can really do is try to find a current week code and a Malaysia chip...

[Zroc]

There's something really important to realize, though, Kunaak.
It really is a crapshoot. Not long ago, I built up 18 P4 2.4C's...all the same batch. At default core voltage, the highest hit 3372, lowest hit 3060. Unlike the athlons, there's always going to be a bit more luck involved. Hell, I once had 12 2.0/400's, and the worst wouldn't do 2.6, and the best did 3.3...again, all the same batch.

There really isn't a magic batch number for P4's.
Hell, if there was, we'd all have 2.4's at 3600 or 3.0's over 4GHz ;)

It's a crapshoot.

[Kunaak]

yeah, I kinda see that now.
having been an AMD guy for the first year of my OC life, I never paid all that much attention to P4's, but now I have had a few P4's and am learning, they are really about luck more then anything...

no DLT3C or AQXEA to look for :(

[Ragnarok]

u look for s-specs + core week (not packaging date) + plant of origin

Personally I am supersitituos and always go for th 'L' Malaysian chips

[Neptune5k]

I just got my 2.6c today, I'm going to get everything set up later this week. Anyways, its from the Phillipines, are those good overclockers?

[Kunaak]

not usually from what I hear :(

[Boogotop]

i really like my 2.6c from malaysia :) on my ic7 the max i can reach is 303fsb....but on this crappy MSI Neo2 865PE i can run it 24/7 at these speed

[Kunaak]

Boogotop, how do you like that MSI?

I am probably gonna need to replace my P4C800 here soon.
I seem to have some weird block on my CPU voltages past 1.6 volts, and no one seems to know why :(

[sandman]

What would happen if you did a volt mod, but only increased the voltage up to what it should do from the settings in the Bios.

[Kunaak]

I have no idea, but I'd rather just get a different board, then bother with that. Vdimm mod is the only one I wanna do, but if I can't get the Vcore working above 1.6, then the Vdimm mod on this P4C won't do much for me.

[QuadDamage]

yo Boogotop,

what's your max benchable speed of your chip/mobo? also, does your chip like 1.7v+ v-core?

edit ;

what's the problem?

[Johnny Knoxvill]

just something interesting i found on another site.

quote:


Just to clear something up, the markings on the back of the CPU refer to the packaging site - not the manufacturing site of the actual silicon chip itself. Intel has no fabs in either Malaysia or Costa Rica, they are packaging facilities. The silicon die/chips are manufactured elsewhere in the world and are shipped to either of these two packaging sites. In addition, Intel manufacturing has a goal of running a "virtual fab" - meaning that, among other things, products from one fab are statistically indistinguishable from those manufactured at another fab. So even if, for example using fake names, Malaysian packages used chips only from fab #1 and packages marked Costa Rica use chips from fab #2, there should be no difference statistically between these two.

The silicon is what defines the speed of a CPU, not the package. And the silicon comes from multiple fabs scattered all over the place that are all supposed to be identical anyway.

There's been a lot of discussion about which Northwoods are better... Ones "made in Costa Rica", or the ones "made in Malaysia." The problem is, no Northwoods are manufactured overseas. All are made in the USA, with the vast majority coming from Fab20 in Hillsboro, OR. They are packaged (in the Socket 478) overseas, but that has no effect on the overclockability.

Normally, these discussions don't raise an eyebrow from me... But lately I've seen resellers charging more for "made in Malay" chips. And in my opinion, this is a ripoff. I just don't want to see people get taken.

i don't really like the mobo...he don't like all memory stick..

twinmos pc3700: can't pass 266fsb
Geil Golden Dragon pc3500: can't pass 240fsb :(
hyperX pc3500:313fsb no problem

today i will try with some Corsair XMS3500

4068mhz look like the limit of the chip/mobo....and no prob with 1.7v or more

today i'll put the 9800 on it and i will try 24k ;)

Quad Damage, my issue with the P4C800 can be found Here. (http://www.xtremesystems.org/forums/showthread.php?s=&threadid=15966)

[QuadDamage]

Kunaak,

i had similar issues with MSI Neo2. To get 1.7V actual, i had to set the v-core in bios to 2.3V. However, the second board i got wasn't undervolting. I got P4C800 myself now and i must admit the voltages are very stable. I think you got bad board and should replace it if you can.
