Lets look at the bad Northwood chips

[PhoenixOfWater]

Hi, Every time I come here I read a thread about someone not being able to overclock there northwood cpu but I haven?t seen a thread taking just about it, most people just think they can run out and buy the CPU and mobo thinking that they will get a 2.4Ghz on a 1.8A or 1.6A (me being one at first) so I made is thread to show people that just because you have the same CPU, mobo and Ram you may no get the same overclock

So I would like to have people list they bad overclocking of the northwood chip
(?Bad? being under a 400Mhz over overclock) and please list all the info you can
(Please list only if you have pulled your CPU to the max. This is opened for all northwood chip not just 1.6A and 1.8A)

I?ll start
1.8A Date 5/8/02 Ver. 3
Asus P4B533
Running at 2.1Ghz@1.65
Ram is Samsung DDR PC2700
500W Power Supply

I have tryed may things but i can't get it to run stabe at anything higher then 2.1Ghz

I have a buddy with the same problem (at the moment):

1.8A
Abit BG7
2.1 GHz (vcore 1.5)
Crucial PC2100
350 Watt PS

I have seen many as well, but I would have to say half of them get resolved...often it is related to their inexperience, bad bios settings, instability of other hardware, etc....

Most also whine when they don't get the super high oc, but still get a great oc when comprade to what the athlon xp is putting out....


I still think it is pretty good odds you will get a good oc....

3 chips here over the 6-8months...even inclucding a 12/01 packing date and every one of them has at least hit 600mhz oc with default to +.15vcore....I am batting a 1000....look at my sig to my best to date...just starting to play with my new 1.8a (w/ 6/14/02 packing date)...

Yes i know its that but some of its is that the CPU will not go any high..all i want to do is show that if you run out and buy one that you need to do some work to get the speed that you want and still you may not get a i

 

[fatbaby]

is 6/7/02 a good packing date for the p4 1.8a? me doesn't know jack sh!t...

 

[Freejack2]

We got a 1.6a for my wife a few months ago. System wouldn't boot when the cpu got much about 1800mhz. Turns out it was the mouse going nuts of all things. Once I put the mouse on the ps/2 port the system does 2.4ghz.

 

[Duvie]

Fatbaby,....The later the better...The later the date means it was likely fabbed later and thus taking advantage of intels higher performing chips...Since All chips are cut from same wafer they are all theoretically 2.53ghz chips out of the gate. For reasons of minor defects are filling marketing needs they all don't become 2.53ghz chips. I hope I am not insulting you...You likely knew all this....


I think the main thing to watch for are the supposed 1.8's that are running with the decreased die size....I think the code one wants for a 1.8 there is like 66Q or 68Q...something like that...


Either way you likley have a chip that may do 2.3-2.4ghz at default vcore (133fsb)....May go as high as 2.6-2.7ghz with 1.65v....

Is yours a rev 003 or 004??

 

[fatbaby]

mines is an 003, how do i know of its a 68q or a 66q?

 

[Duvie]

look on the box for the fpo/batch #....List all the numbers on the white label and I can tell you...

I think you are looking at a potentially a very good chip to oc!!!

 

[fatbaby]

fpo/batch #: 3211A626
Version #: R78297-003
Pack Date: 06/07/02
MM# 842169
Prod Code: bx80532pc18000dsl63x

 

[Duvie]

Nope...It is 63x there at the end of the product code....The advanatge as stated before is that it is a later 1.8a chip and over time the 1.6's and 1.8's have been successfully getting higher and higher at defualt vcore....

I am not sure if anyone around here as got a new die shrinked p4 1.8a anyways....


Go play and find out!!!

 

[Duvie]

BX80532PC1800DSL63X
MM#: 842169
FPO/BATCH#: 3219A043
VERSION#:A78297-003
PACK DATE: 6/14/02

Here is my new 1.8a info....A lot like your!!! I will find out tonight its true potential...

 

[etrin]

My 1.8a is a lemon.

BX80532PC1800DSL63X
MM#: 842169
FPO/BATCH#: L146B053
VERSION#:A78297-001
PACK DATE: 12/27/01

from the cpu core
SL63X MALAY
l1468853-B483

This cpu won't do 112 FSB on my ASUS p4b266-c with crucial 256M PC2100 memory
It will boot into windows at 109 but takes about 1 minute to open a folder and 5 minutes to shut down.

Someone said it was a bad chip and return to INTEL but I don't have any idea about that. and don't have 2 -4
weeks to spare to get a replacement.

This doesn't sound like a cpu problem by the way...

If the chip runs at default then the chip isn't faulty..Intel sold you a 1.8 not anything else and if they live up to that end of the deal then oh well on the chip....


I had about same info on my earler 1.8a...same packing date...malay...and it reached 2.4ghz w/ 1.65v on an asus mobo with kingmax pc2700 ddr.

Repost:
Hello! I have been trying to overclock my P4 1.6a with many problems. I still cannot get it stable beyond 1.6Ghz. Here is my rig:

Epox 4G4A+
P4 1.6a CPU (Costa Rica 6/04/02 pack date SL668 1310A823-1374)
ASII well applied
Zalman copper heatsink
2x256mb Crucial PC2100
GeForce3 TI200
Seagate Barracuda 80gb
TurboLink 420watt dual fan PS

Even with 1:1 memory settings, AGP/PCI locked, and increasing the vcore all the way to 1.70, the system isn't stable under long term testing with any frequency beyond the default 1.6Ghz. I can't even boot at 533mhz bus of 133*16=2.12Ghz. Windows won' t load at anything higer than 120*16=1.92Ghz and long term stability isn't achieved with anything over 1.6Ghz.

The system temps are in the mid 40s (usually 45-47)C with the system at 1.5vcore and 1.6Ghz. At 1.92Ghz and 1.6vcore the temps are around 50-52 after long term testing. But it will usually fail in an hour or so or while playing video games at 1.92Ghz.

I originally had an Antec PX303 300watt PS, so I replaced it with the 420 on the theory the old one wasn't good enough (it was from pre P4 days)... but I notice no difference with the new PS.

I have tried removing one of the DIMMS and leaving only one DIMM in slot 2, per the advice given here, no difference. I've tried different memory timings, no luck.

I'm running the 4/24/02 Bios from Epox... I've read several threads here that advised against upgrading to the newer one.

Is there anything else I can do? Do I just have a dud here? Could it be the board? I _really_ wanted to run 16*133=2.12Ghz I'm almost tempted to sell this CPU and order a 1.8a and give it a try. But if it's my board that is the limiting factor, I'd be just as screwed.

Thanks for all your help here! This isn't my first overclock by any means, but it is giving me the most trouble!

 

[PhoenixOfWater]

wizz0bang : Have you try overclocking it with just one stick of ram?


There a lot more people overclocking 1.6A Vs. 1.8A ...why, can you get a better overclock on a 1.6A?

 

[wuaffiliate]

hi,

bought a p4 1.6a yesterday just before they start going up in price i think anyways this is whay my prod id is anyone know if its a good thing?

prod code: BX80532PC1600DSL668
MM# 844085
FPO/BATCH: 3211A593
VERSION: A82110-003
PACKDATE: 05/15/02

cpu engraving is:

1.6a GHZ/512/1,5V
SL668 COSTA RICA
3211AsA3-0122
Intel (m)(c)'01

any insight would be much appreciated

 

[PhoenixOfWater]

What Mobo are you going to try to overclock the chip on and what ram are you useing?

 

[Jgtdragon]

I got a lemon too.

pack date: 12/27/01.

1.8a

It can't do 2.4ghz at even 1.7v.

Currently running at 2250 at 1.625v.

 

[PhoenixOfWater]

Wow.. It looks like there are more 1.8A lemon then 1.6A...
I think i am going to get myself one of the 1.6A (the price are going up right? )

if thats meant for me il getting the MSI 645E Max-C and i have Kingman 256mb DDR2700.

Sorry about that....i have hear good things about the ram that you have, but i really do not know about the MSI's Mobo...i have only used Asus on my own computers and i find them to be better for overclocking of any chip (Intel or AMD) the 1.6A chip that you have, i haven't hear anything bad about that PACKDATE and others with the 5/??/02 date have geting there chips up to 2.4Ghz and more..

 

[Duvie]

Take anything with a pack date of 12/01 with a grain of salt....Many from that timerarely did 133fsb or 2.4ghz. At that time the best Intel chip out was only a 2.2ghz...Since the 1.8's rarely got to 133fsb to lock the agp/pci down that is really when the 1.6 push began...It usually got to 133fsb or 2.133ghz and usually topped out around that same 2.2-2.3ghz range....


The main chip out today is the 2.533ghz with the 2.8 coming out this month...That is likely why june or greater pack dates will start pushing up to the 2.7-2.8ghz range...In May the best out was the 2.533ghz and many were getting 2.4ghz at default vcore with 1.6's and 1.8's...check past threads...most got to2.533ghz with minimal vcore...The days of 1.8+ vcores are goingaway yet the speeds are getting higher with the lower speed chips still....

Since 1.6a's have been discontinued awhile back it is unlikley they will take advantage of the ramping up to 2.8ghz speeds...

 

[PhoenixOfWater]

Duvie-
so are you saying that the newer the date the better of an overclock you could get?

 

[Duvie]

YES!!!!

Since the chips are all made from same wafer they all start out withthe intention of being whatever is the latest and greatest intel is ramping to.....

Not all those 1.8's are there cause they can't go higher speeds...INtel gets good yields but bins them for marketing needs...NOt everyone want to spend 600 bucks for a processor...

12/01 1.8's maxed around 2.2-2.3ghz

4/02 1.8's seemed to hit around 2.5ghz

6/02 1.8's I have seen so far are getting to 2.7ghz

some of the new 66q or 68q die shrink chips are getting 2.8-2.9ghz...
