In case you guys didn't know. There is a difference in terms of the Batch/FPO of the conroe CPUs. For this discussion, am gonna focus on the E6600.

If you guys look at the side of you intel box or your CPU you will notice somthign liek this : L628B121

28 - week (i.e. week28)
B - AFAIK there is a A and B series
121 - NFI

p.s. If you have the week L28B batch consider yourself lucky. It's proven to be OCable to 4GHZ stable with under 1.45 Vcore.

p.p.s. Currently have the L26A batch and it sucks shit Only able to get to 3.33Ghz with 1.55Vcore !!!!

I'll like to find out what the batch/fpo for most of the ppl here. Would be great if E6600 users can share their batch numbers here

Cheers
Hot CHoc

So 4GHZ definately can overtake a FX-62 already right ?

I would be grateful if someone could provide all the details of how overclockable between different batches of Core 2 Duo processors.

I have week 30... but dunno how far it can O'C...

The CPU still in the box

Update:

L630A768

Who said Week 30 cannot o'clock to 4G?

http://www.xtremesystems.org/forums/showthread.php?t=115109

Can we have our own malaysian database on E6600?

Can you please look at the side of the box (where the sticker is) or at the CPu to read the whole batch/Fpo number ? i.e. L630 ......

Many thks

My E6300 is week 26, so far the overclockability is acceptable to me, just wondering is there other batches can go better..

consider lucky if can find the 4ghz batch...

You can try international forums where they did some benchtesting on it

Cheers
HC

Can you guys please list your fpo/batch number like this: L628B121 (side of your intel box or printed on your cpu)

cos will be coming to kl soon and i wanna know what's the common batch available in low yat

i have L629A****, still in box ...

Many thks

Am trying to look for this series: L628BXXX (heard all the top OCers looking for it in the US)

AFAIK week 30 is not very ocable..

i assume yours is the week30 ?

mine is E6300 L626A422
does ths means mine is the A bathc n not oc-able?
im running 2.8 now...hv try higher

L623, L626 abd L628 is the most OCable referring to the other OC thread...

The A or B series? Is there even a B series available in KL ???

betul ka u cakap ni?? for ur info, we do have our elite here using this L628B but it seems pumped 1.6v just to reach 4Ghz barrier, its HERE

if u have the related source(s), do share us the link here. as far as i know, e6600 need atleast 1.45v just to stable around 3.4Ghz. u can see Y 4Ghz need more


for e6300, its diff la kawan
average e6300 can do the least 3.2Ghz
if not, then something might wrong wif ur system

6300 avg can go 3.2? wow, my friend can get it max at 2.5 only, dont know what is wrong maybe limited by the memory , he has a pair of corsair XMS

28 - week (i.e. week28)
B - AFAIK there is a A and B series
121 - NFI

I think I read in xtremesystems,

28 - week (i.e. week28)
B1 - Batch Production Code
21 - NFI

It's a code to differentiate between the batch of production. ES, OEM and Retail. Not so sure though. I'm still on AMD.

Refer to this url: http://hardforum.com/showpost.php?p=1029688&postcount=1

The results were posted back in July/August 06. Imagine the results by now. Prob. way higher than we can ever imagine o_0

Conroe Stepping Info---Conroe Week------Conroe Code (The Week and Code are found on the CPU box and on the CPU itself.)
A-1 = stepping 1-------------In form of L6##----In form of A###
B-0 = stepping 4-------------Example: L617A846= Week L617 Code A846
B-1 = stepping 5
B-2 = stepping 6

wahh, xmx onli can 2.5Ghz?
should be lack of OC skill there
my last e6300 paired wif onli kvr able to hit 460 x7 at 1.36v onli


thanks bro
that the way should be
my current e6600 running at 3.2Ghz at 1.325v onli

What batch number is urs btw ?

Its all luck and skills guys....not so much of batch numbers.

Trust me on this - its more luck than anything else!

This post has been edited by kcnyc: Oct 18 2006, 10:40 AM

A-1 = stepping 1
--> ES

B-0 = stepping 4
--> ES

B-1 = stepping 5
--> QS

B-2 = stepping 6
--> Retail version.

ES means Engineering Sample....

QS means wat? Quality Sample?

Ur fren pair with what MoBO brand?

Qualification Sample....close enough to retail version to do reliability test..drivers..yada yada.

In other words, means retail chips perform better in OC?

Nope....like the dood said... a lil skill, a lot of luck and the pre-requisite sacrificial offerings to the pagan gods of hardware.

I want the "B" series >.<

im not using e6600

btw..L628B121 able to do 3.6ghz at stock vcore..but if want to hit 4ghz,need around 1.4v to make it

edited:don think can find "B" series in malaysia leh..

This post has been edited by coolice: Oct 18 2006, 04:20 PM

Damn. I think the only place B is available is Taiwan/HK. Own country manufacture these chips but i can't get hold of em. Quite pissed actually

guess so..haha..
go to rob intel in pg

My friend works in the quality inspector for Intel in Penang. Maybe can ask him? hehehehe

But seriously, the "B" batch is not available in Malaysia?

Can some good soul here confirm this please?

dono..try to find in lowyat last time but cant..
may be can ask those who owned a shop

Colice you mean you tried looking for the B version in LowYat before as well ?

ya..but failed

so wat batch/fpo is urs now ?

- EDITED -

Help in finding the l6XXbXXX batch guys

I have a few friends who have the b revision. they get it from us.

Wah. All the way from US !!!

Just to let you know, the retail chips are doing much better in general than the ES/B chips. And not all ES chips are good overclockers........again it is all luck. Some people buy ES chips just to find out that they don't overclock well. So don't be too hasty to get one.....

The only thing I think the ES/B chips is worth is the unlocked multi. Other than that, they are mostly the same with the retail chips.

I thought all the CPus now should be retai lversion

You check it via CPUz right ?

This post has been edited by hotchoc: Oct 19 2006, 08:32 AM

You can still buy used ES chips. But you just have to find it.

Yes CPUz will show that it is an ES, but sometimes not.

Speaking of which....

Anybody can explain the VPO number?

Chargy??? Where are you???

how bout ur current 26A chip, can OC high or not?

It sucks shit

Need 1.55Vcore to go to 3.33Ghz

Was aiming to get 4Ghz (400X9) but the best i could go is about 370X9 stable

Gonna get a L630A to try.

Do lmk if you knwo where to obtain a 'B' batch

This post has been edited by hotchoc: Oct 19 2006, 08:11 PM

wow, tat very gay man
3.33Ghz at 1.55v??

will update my stepping later if i manage to get 3.4Ghz stable under 1.5v
currently still trying to increase speed of my e6600

It is !!! Week L628B121 = ownage

Guess i'll stick to the A version for now unless someone can direct be to the B series

This post has been edited by hotchoc: Oct 21 2006, 10:30 PM

WTA. Currently all retail processors sold in lowyat is B version meaning Retail Version? Any retail processors with A labeling? Thanks

What i meant is the batch number L6XXBXXX not the B2 revision

Sorry for the misinterpretation. Yeah i meant the batch number A/B that was referred by you . I heard somewhere retail units having L6XXAXXX? Is that true? I thought A & B also ES only B2 is retail right?

Thanks

I guess you have messed up the definition of batch numbers and steppings.

All E6600 should be the retail version now with the B2 stepping though you can still find some ES (engineering) version

Batch numbers come in the form of A or B of which A is easily sourced compared to the B (i.e. L6XXAXXX vs L6XXBXXX)

I don't think the A and B differentiate a lot, the week does.... It's all luck i say

Just got info from my friends working at Intel as xxxxxx(cannot mention here)

It's true L6XXAXXX is lower compare to L6XXBXXX in overclocking performances.But sadly this L6XXBXXX batch are only for export to mainly US market and europe recently.He said to me that all the proc are made in the same production weeks.Only at the last stage they will test the proc with some performances testing device before E-labeling into A or B type.Curenttly A type for local market or around south east asia.Since Intel is American company,they will give more priority to their end user compare to us.Also u can compare to their price+convert USD to RM..still their proc retail more expensive than Malaysian market price.

PS: I'm trying to get/buy E6600 L6XXBXXX batch from my friends working there but it so hard since staff purcase only can get ES version,but very cheap.. RM 400 only. .Hijack their warehouselah if dare..but be prepare cos more than 4 polis bantuan(not ordinary jaga) working in per shift with all their revolver & pump gun.Their security are more tight compare to local bank

now i know... erm..

Let's go rob em. hahahaha

Nice infor btw

rm400,so cheap?then mjoe realy untung banyak loh..

Hahahah..if u dare..why not?..
OFF TOPIC <--Just For Info

Last time i'm driving at PLUS highway & meet with their convoy with 2 lorry kontena + 8 unit (4x4 Storm).Totaling 16 security personal fully firearm just for deliver the proc from Penang to KLIA with their very own courier plane...

PS:Maybe hijack their plane is more easy

Not really...cos every staff only can buy 2 unit proc per years.. Better hit their MINAH KILANG as a platform to buy cheap proc..

hahaha. i wanted to buy from europe/us but after weighting the pros and cons - tax, warrant, shipping it ain't worth it

be getting the week 30A and i'll let you guys noe how did it go

thks for all the support

btw, will be in kl from 20th nov - 26th nov anybody wanna come out to lim teh ?

Well, just got my E6600 n DQ6 today...but just the matter of time to get my hands on those DDR800 high perfomance RAM, right now have to stick to shitty OEM RAM.

Anyway, manage to get 3.014GHz on stock vCore @ 1.32500v, still testing out SP2004 to c how it goes...

Btw, it's L629Axxx

aiyarkk.. if onli i live in penang, sure everyday take minah kilang jalan2 cari makan

btw, is the ES processor has unlocked multiplier same as x68series?

just downward..

i have one E6600 ES and its only unlocked 6-9multi...

Guys, i finally got the "b" series.

eheheh. gonna test it out

izzit? tot ES having the same as X68 ability, fully unlocked multiplier


nice. awaiting for ur result here
let c how this B rev. overclock ability

Gonna try with the stock intel HSF though. My Noctua HSF is still on the way. Probably. a deviation of +/- 5~10% in terms of OCing i'll say ?

proof...

hi there
what the highest speed, vcore & prime stable can u get with this ES e6600?

i din't try about prime stable, but hv super pi test as below...



Attached thumbnail(s)

ic. mine can do 3.2Ghz@ 1.325v onli & prime stable
but for 3.4Ghz, it cant be stable even i feed upto 1.475v

seems my cpu stuck or mobo holding me back

u use ds3 arr? actually i'm running at 1.575 vcore. i wonder y when i push it beyond 1.6vcore my pc terus restart....is it over voltage for mine ds3 or proc.?

yep. me oso using DS3 rev C2 mobo
1.6v maybe too high to ur cpu or might hold by temp

This post has been edited by gengstapo: Oct 27 2006, 02:45 PM

anyone here has a week 27 A E6600?

i've lost my screenie...

but, max is 3.4gig @ 1.4500v but the temp reading (using ET5) after 10hr priming almost reach 80C!! and that with zalman 9500led!! (sold it oledi).. guess my 24/7 is 3.2gig only at 1.3875v.. that's enuff.. additional for just 0.2gig for almost +0.1vcore and almost +10C temp is not worth it IMHO...

huhuu.. high temp liaw

E6600 L28BXXX

Vcore at 1.35

Damn stock intel cooling. Giving me high temp >.<

well, even dualie super pi 32mb cannot prove ur system stable enuff
coz if run orthos sure fail sometimes within a minutes

Bump for this topic.. can new C2Duo ownner share some result here??
proc week and o'c results

No ppl wanna post their proc week + o.c result here??

E6300, L627B123.. Current O/C at 2793MHz @1.3V Vcore on ASUS P5B E-Plus

trying to get higher. Anyone else with week 27 batch of e6300?

Ok.. i share mine here, but I cant find my proc week(actually dunno which code to refer), maybe bcoz i m using E6600(E.S), Stepping 4.Mine can hit 3.55Ghz, vcore=1.6, using Biostar Tforce 965PT, cheap Atrix 500w power supply and unknow brand air cooler.... SuperPI 1MB 14.2xx second.

L629A807 THAT mine e6600 push it before @ 3.6ghz but think my ram is not at the par of runnig 800,so not stable...corsair value select 667...haih need a performance 2gb kit la..

1 question here...

All E6600 can be overclocked to 3.0GHz easily right?
Because my target only 3.0Ghz.

This post has been edited by norazwan79: Dec 23 2006, 08:45 PM

Yes very easy. Even E6300 can do it with 430fsb.
for ur E6600 just need <340fsb.. far more easy haha..

thanks bro.

AFAIK, in order to get higher FSB try 3rd party cooling for the NB and the CPU cooler

< heat
> stability
> OC

i got 1ps..L630B013..got it from my cousin..didnt test it yet cz waiting for mobo n ram

sorry for d noob question,mine is e6600 ES..so how to know d week n batch 4 my proc? thnx:)

i think this is the batch, frank_fusion.
