I am dissapopinted with the 2.8 northy. This is my second one and as the first it is not Prime 95 stble with any fsb over 150. it failed at 160 immediately and wouldn't even pass a single madonion loop. It failed at 155 in both Prime and Madonion even with the voltage upped to 1.6v. I even tried 153fsb and it was also bogus-city. The highest stable oc is 150. It looks like these C1 steppings are reaching thier limit.

1) P4 2.8
"Malay"
pack date 8-26-2

2) P4 2.8
"Malay"
pack date 9-27-2

Kinda sucks cause my Corsair pc3500 is barely being used to it's potential. Right now I have it running at 400mhz-(sandra 3038) and I was able to bench it at 160fsb which gave me 427mhz-(sandra 3241)

Atleast I'm not the only one.. My 2.66GHz C1 did like 2.9GHz and my 2.4C1 can't do 2.5GHz.. Those guys at intel are slipping..

no....you just have high expectations from C1.

looks like it's time for the cpu's that have been tested to OC well.

or use rambus.:p

I'm stickin' to my theory JD :) .. tried many chips over and over, with friends, their friends rigs all over the place.. nothing impressed me.. Max I saw was 500~600Mhz OC .. even if I don't sell this chip, I'll pair it with PC4200 and slap it on my P4T533 @ default 4x + Turbo and it'll be my video editing rig :)

Yeah bro thats real nice! Too bad it was a celly (stripped p4). I really think these c1's are just about at thier limit. What are the chances that 3 2.8's (pacino's & mine) from different parts of the counrty end up with the same oc results? i bet the hyperthread chips will do better. ;)

Yeah yer right...it is luck of the draw. But it sure seems like a lot of peeps are getting bogus luck...time after time with these new c1's. I sure hope Intel isn't turning a cold shoulder to us Oc'ers. I hope this is just a little bump and not the future. I would really hate to go back and spend all of my spare time at the AMD threads.

ROFL! ... no, I tell you what I want to do, 2.8 @ even 3.4 is no fun, what I want is real OC, 1Ghz would be nice :D .. I was close with my 2.26 @ 3.2 but the vapo + BD7II + chips all went banana on me, don't know yet what caused it but it was a nice experience LOL! yet, I want to try this again on water! :cool:

Leave it to JD to bring reality into the picture. ha ha ha Yeah bro dude...150 @ default is good enough (for now). I think we are conditioned with fsb lust. We are so used to getting insane oc's that we just expect it everytime. I know I do, but I should be more realistic...yeah thats right...I am using the "R" word. he he:p

the 1.8a didn't do that great in the begining....now look at them.

I think it was the same for the 1.6a.

lemme add my 2.8 chip in here also...it is a 32 week costa rican. OEM chip. it did 3ghz default voltage 100% prime stable. the max i got from it was 3105ghz on 1.65 vcore on a p4b533-e 100% prime stable.. it was air cooled with a alpha. im about to setup a rig with water cooling...ill let u kno if anything changes....but that wont be for like a week or 2. but ya...im dissapointed with my $400 chip. and i was getting crazy temps of 63C on full load with 1.675 @ 3105 and @ 3ghz i was getting around 56C max. it was making so much more heat then previous P4's i owned. my 2.5 C1 ES chip also dissapointed me as well i only got a 105mhz OC from that 100% prime stable. but i was running insane fsb speeds.

11-02-02, 06:07 AM

i got my new p4 2,8 too
had 2.5 c1 abit th7 II and prometeia cooling before
for some strange reason it didn't even make 3000 stable
so i decided this can't be it and build up a new machine

p4 2,8
abit it7 max2 v2.0
pc 3500 corsair cl2

im pretty happy so far , the max stable oc i can do is 3498
fsb/ram is 166/222 so my corsair is pretty much at its limit too :)
at least i think its stable
i pass super pi 32m test in 42mins
my expirience is that if there is the smallest instability you won't even pass loop1 of the super pi 32m test
so if you complete the whole test the system should be stable
at least the cpu , the ram still may be unstable i think and could produce crashes in some other applications
but i didn't have any crashes so far , so i think its stable ;)
i hoped for some 3600 or even 3700mhz , but i think 3500 should do it for a while ;)
it's a malaysia 08/26/02

my idle temp is -18°C and full load temp 0°C @1.8vcore
prometeia seriously kicks ass , vapochill is in my eyes no match to prometeia ;)

Horus bro, yuor 3700mhz p4 has the same pack date as my first chip. Looks like you got a good one there. About the Prometia though....with p4's I am not so sure that colder is better. I have lost several chips from small voltage elevations coupled with really low temps. It's nice to see that your chip is doing well...it seems to be the only one around here that is in the 2.8 family that is doing well.:burn:

pacino

11-02-02, 09:53 AM

I came to a conclusion, B chips don't like cold atmosphere :) .. don't go below 5c .. if you're chip is rockin' right now, it'll probably start to die in 4~6months from now, which ain't beauty, that's why I built my watercooling setup yesterday.. temps @ 33c load = my P4PE overvolts, hope a new bios will fix dis...

it's just 3,5 not 3,7 ;)
well he does fine cause he's 3days old now
maybe this could change , i don't hope so :)
what dou you mean by "i have lost several chips from small voltage elevations coupled with really low temps" ?
why could lower be worse than higher ?

and not going below 5° would be a problem with prometeia cause it just goes below or is there a way to config the prometeia controll ?
i had a look at the controll but couldn't find to modify anything
there were just a few numbers and i don't know what they are good for

No dude I ain't that dumb. I have the white goop in the ziff sockett with it underneath and ontop of the little square foam. I even put a considerable dab of the stuff (white goop) on the transitors on the bottom of the cpu before I stuck it on all the goop that I already put in the ziff sockett.

I even asked tech support at the asetek forums if it was OK to use AS3 on the top of the cpu.

One of my buddies bought a Vapo about the same time as I did and built a AMD rig with a stupid Soyo (Crapo he he) Dragon KT333 board and he put AS3 inside of the ziff sockett and in the pin holes. He called me up and said his computer wouldn't boot. ha ha haha haha ha! So i started to ask him some questions and he told me that he had put AS3 in the ziff sockett. I said, "YOU DID WHAT??" No wonder it won't boot you fried your mobo & cpu moron! He said, "But the AS3 package said it was dielectric!" I asked him just how does 99.9% micronized silver become non-conductive?

Interesting you had such good luck using 1.85v too, as a lot of people running that much vcore eventually wound up with failed chips. If I recall correctly, in the same spec Intel stated max voltage at 1.75. I too tried 1.85v on my P4, but just long enough to find out it wasn't going to help me OC any higher. :(

a friend of mine who bought a 1.6 northy, is running his chip for as long as a I remember @ 2400mhz using 1.85v till today .. I wish I'm some sort of an engineer @ INTEL to find the difference between A's and B's .. I don't think it's only a pin that is not connected, which will adjust the multi / bus. "A" chips seem to live longer in my dilemma.. or B0's at least .. aaah gotta figure this out before I go bankrupt! LOL!

My 2.8 was running fine at around 3.45. then it began to crash in UT2003. i figured i'd run prime 95. Well it is not prime 95 stable in anything over about 145 mhz FSB at any voltage. This rig is water cooled too.

Dang bro...sorry to hear that. How long did you have it running at that speed/voltage before it started to go unstable?

11-03-02, 12:15 AM

off and on the entire month of october. I dont think it was ever truly (prime 95) stable. I am just an idiot and never thought to torture test it.

I was really hoping for a 1000 mhz overclock that was fairly stable. But nooo, intel wants to make enemies, not friends.

in my opinoin the p4 2.8 is a good overclocker.
Mine is running @3213 Mhz with 1,57 v. and it is totally stable. my max temps are about 38´C. i can get higher but over 3.3 Ghz it gets unstable. i´m still using the intel stock fan, prometeia is comming soon. hope to get 4ghz :)

What ever gave you any reason to think you'd get a 1 GHz overclock from a 2.8 chip? Because people got one from a 1.6A or 1.8A? Did you ever think it might be a different situation with a 2.8?

If you truly understood the nature and capabilities of these CPUs, you would have known that this was unrealistic If you had asked me, I would have flat out told you that.

I've said over the course of time on the front page that these Northwoods wouldn't do a lot more than 3GHz. Generations of CPUs have inherent limitations. Short of using extreme measures, you can't expect to greatly exceed the maximums Intel itself expects from a generation of CPUs (which looks to be 3.2GHz).

(BTW, water cooling really doesn't help maximum speeds very much.)

Don't blame Intel for you not doing your homework before spending $500. You made a mistake and it cost you. It will cost you even more if you don't learn from it.

I try to set realistic expectations in advance for upcoming CPUs. Some people tell me, "Don't give me opinions, give me facts, and let me decide for myself." Then I see how they decide for themselves. They find one fact that tells them what they want to hear, and proceed to throw their money away.

This is very frustrating.

P.S. to others: I wouldn't expect to get 4GHz using a Prometia, either. Something over 3.5GHz appears more realistic.

http://www.overclockers.com/tips065/ this did.

some of my older B0 stepping p4s had no problem going another 300-500 mhz with an alpha HS/delta and good system ventilation. This POS 2.8 wont even do that with water cooling.

don't wanna dissapoint you
but i thought the same buying my 2.8 and owning prometeia
you will never reach 4ghz even under best conditions :(

i prime tested my rig yesterday
as sateted above its stable at 150fsb even at 1,5vcore
but it won't do any higher even if you throw 1.85vcore at it
it never will be prime stable
but maybe prime has problems running high speeds ?

@runsalone: Another reason why I hate C1s, pro'lly for the time being, Don't you think INTEL did this on purpose due to high volume of CPU returns + spies all over this forum? LOL!

@TbC: I highly doubt it, you will probably hit 3.6 Max, and probably won't be stable either.. I repeat, cold environment, will kill your CPU in the long rung..

You know what bro...I had thought about that too...several times even. If Intel wanted some free research or even wanted to know why they were getting so many returns on thier cpu's all they would have to do is come and register at the forums here. I have cable TV and I like to watch "Tech TV" all the time especially the show "Screen Savers" they had some guy call in and ask about overclocking his Intel mobo (yeah right) they told him that he was out of luck...in a bad way! he he but then they showed the front web page of our beloved forums...yeah thats right "overclockers.com". They recommended our site to the public. Cool hunh? But what I am getting at is if they know about this site I bet you milllion dollars that Intel has taken notice of us too!

so u would say it is a waste of money to buy a prometeia to get higher speeds
(i know that 4ghz a nearly impossible :P )

A prometeia is just a very good cooling system. Issues of frostbite aside, such a system will provide you with a good chance to go above what inferior cooling solutions can offer you. How much and how often that happens is partially dependent on the cpu and system choices you make, but also partially dependent on luck.

With the current C1 chips some people had trouble reaching 'even' 3Ghz. Equipped with a Prometeia, I'd expect 3Ghz to be easy on almost any of these chips. 3.5Ghz is a cut above that and I think that it is possible, but far from guaranteed even with such cooling. And yes, 4Ghz is off the radar.

Ladies and Gents!!!!

This is the CPU 2.4b 355FSB, SL6EU steppin. I just bought it this saturday along with a ThermalTake 7+. HOLY S|-|it!!! I can do 3150@175FSB Stable with 1.7V and only 45C on die temp.

I found a mojor problem though, i get lower marks in Sandra and 3dmark if i run it at these speeds. If i set the FSB to 164FSB and 3:4 mem, it scores much higher then 175FSB. I guess mem bandwith is more important these days then raw CPU power.

I need to set up this innovatek kit on here and see where it goes from there.

Here is my 0.2: Get an 2.4b with a SL6EU ending, any respectable retailer looking for your business will be happy to seek one out for you in their inventory. Make sure its made in the Phillipines

"1st letter or digit=plant code

1=Cavite,Philippines
R=Manila,Philippines
7=..........,Philippines" Thanks TASOS

A nice copper fan and ArcticSilver3, with this setup you should have low temps and a ROCK stable operation.

Now, why buy chips from the Philipinos!:

"Intel Corp. has announced plans to pump in another 4 billion pesos or 5 billion pesos US$78.3 million to $97.8 million) into its manufacturing plant in Cavite, the Philippines, to ramp up production of Pentium 4 processors using 0.13 micron technology."

Obviously Intel wants to make a point that making the best of State of the Art technology in Asia is a great possiblity. I'd rather buy something that was made on a good assembly line such as in Stuttguard or Munich as oppsed to something made at Detroit. Granted both will perform good at default but which one will give you the ultimate performance?? :) Sorry my crappy political opinions coming out! NARF!

Any who thats my 0.2 worth, maybe 0.5. ;)

You won't get more than whatcha gettin' right now, maybe 3.4 the most with low temps, but I tell you this, how long will this last? .. are you planning to kill your chip in 4~5 months? .. if yes, then go ahead .. extreme cooling DO kill northies and they die faster than the period I mentioned..

we will see
mine is meant to last at least 3 months ;)

i try to get the max stable fsb frequency passing prime95 now
fsb by fsb im testing
at the moment im running 154/3244mhz @1.50vcore
can hold the vcore pretty low at this speed
but there seems to be a border , when crossed even massive upping of vcore wont help anything more
i think this border is in the region of 3360mhz
what could be my problem ?
or is it just the chip reaching a sudden end of the line ?

So you say that 154fsb is the max stable oc? Actually thats pretty good foe a 2.8. My max is 150fsb and just like you, no matter how much I up the v-core it still doesn't make anu difference.

Yeah bro....looks like you have reached the end of your 2.8.

Horus

11-05-02, 02:18 PM

didn't say 3244 is the end
still testing ;)
but 3360 will be the end for sure
maybe i'm lucky and still get 3350 or something like this ;)

Horus

11-06-02, 01:17 PM

3286mhz
still 1,52 vcore :)

Is it Prime 95 stable? I can get my chip to run at those speeds but it won't complete Prime 95 past 2 seconds.

prime was running for 6hours
i now went up to 3307 still 1,52 vcore
but prime failed at test 4

restarted it just for fun
now it is at test 6

but i think it is really time for some more juice now :)

the magic border i was speaking of just seems to kick in :/

hmm test 18 and still no fail
maybe it is not as bad as i expected
some +0.025v should do it for the next +21mhz ;)

and still running :D
