2.4 Celly @ 3.2 that's it?

[naughty_guy]

Hey guys,
I'm just starting to overclock my new budget machine for my sister, anyways, first up are the specs:

Intel Celeron 2.4 @ 3.12 | 1.585V (400 FSB, 128 L2 cache) (SL6W4 | 09/30/03 | 7336A396 )
ASUS P4P800 (@ 130FSB)
Antec SmartPower 300W
AOpen GF4 MX440-SE 64MB
Maxtor DiamondMax Plus 30GB 7200rpm 2MB
Sony 52X/24X/52X CD-RW
Samsung PC3200 256mb @ DDR348 (running single channel, 3:4, 2.85V)
No case fan besides stock CPU HSF and PSU fan

The celly will run daily application stable with 1.585 Vcore, but not prime95 stable. I tried upping the Vcore to 1.675, still not prime stable, I didn't want to go any higher fearing the sudden death of northwood cores.

Is 3.12 the limit of my CPU already? What are your celly OCs??

[sandman]

Gonna say that's the limit.

I've never owned a celly, but what are your rails looking like?

[DazzXP]

Yeah looks like thats the limit still a 700MHz core clock is pretty good for air cooling.

[naughty_guy]

rails are hell strong. All 3 rails stays on nice margin under prime95 dual instance stress. Besides, Asus even overvolt the Vcore by a little bit too. I'd hate to believe that 3.2 will be the limit, but if that's the truth....

Anyone else?

[|_053|2]

a celly at 3.2ghz...

is it fast yet? :D

[DazzXP]

The Celeron hasn't gone though as many stepping as the P4 as no enthusiast’s will buy them, even overclocked to the extreme they are still poor peformers.

[naughty_guy]

com'on guys, i noe they're bad performers, but it's a budget system for my sister, my dad only gave me 600 CAD for the whole thing. :( It's not really fast still @ 3.12 of coz, but i wanna get more input...

just got a few more questions here:
is it safe to set the Vdimm to 2.85V and Vagp to 1.8V for 24/7 usage?? How about max Vcore for a celly for everyday use??

[Tedinde]

I've got my celeron 2.2 @ 3.3ghz in my shuttle box. 150fsb, And have had it to 3.6ghz+ in my vapo probably 8 months ago.

The chips scores 5K less in 3dmark clock for clock against a P4 with the same 9700 pro i was using then. 19k VS 13.8k. Same clock.

I got it from Intels IPD program for $62 back then. so i was a good deal.

My 2ghz one i had before it did just as good. and the 2.1 also.

The 2.4's and 2.6's are D1 steppings. I bet if he played with it some more a good heatsink and dont be afraid of some volts he would get 3.5ghz out of it.

[DazzXP]

I wouldn't have your AGP @ 1.8v 1.7v i would say is best for 24/7 but your DIMM voltage is fine.

[naughty_guy]

thx for the input so far guys

so 2.85 for a samsung ram will be fine for 24/7??? And how much Vcore will my celly take 24/7 without dying?? Any guesses?

[rashio]

totally off topic...

DazzXp i see u are from newcastle as well ;)

[Tedinde]

Im from Newcastle. Newcastle county delaware USA, hehe.

[rashio]

lol :toast:

[Tedinde]

Just a little water between us i guess!!!

[Kanavit]

Try running dual channel at 5:4 dude! set memory to 3-3-6-3.

[naughty_guy]

i'd love to run dual channel, but it's a budget system and i can't afford a second ram at the moment.

Please help me out guys....

[Tedinde]

5:4 will slow him up, this is a 100fsb cpu, he need the 3:4 for best speed.

I didnt get any amazing boost testing celerons in dual channel mode anyway when i tried it in my sig rig.

[Kalway]

A little off topic but... Why didn't you get her a Duron? Woulda cost about 1/3 as much and outperform it by a mile. The new Celerons are pathetic compared to the old ones. The P4's architecture needs an assload of cache to shine and the celery doesn't have that so it kinda dies. Not much I can say about em. I work in the industrial computer industry and we haven't touched celerons since the tualitin came out. There's just no real benefit to them.

No actually the new celerons are pathetic compared to the old ones' as in celeron 433-900's. tualitin not withstanding. Which you might as well call a Pentium3

Celerons @ stock 2.2-2.4 do suck, crank them above 3ghz and they arent that bad.

Why get a duron when for $10 more get an XP??

I go AMD all the way for customers, cheaper and faster for a lot less, I do agree with you. Budget and Intel arent words that go together. Guess he has P4 upgrade dreams in the future, that's all i can figure.

I've got to talk people to AMD everyday just about, They come in wanting INTEL but for what they want to spend which is always as little as possible. Always ends up AMD.

[naughty_guy]

i understand what you guys are saying, I noe AMD makes the best budget system, but there's 2 things in my mind that makes me go with a celly. First of all, i dun noe anythin about AMD, and have done Intel for quite a while. Secondly, Tedinde is right, this way i can upgrade to a 2.4C or even a prescot later on.

Will someone give me some words of wisdom on same Vdimm, Vagp and Vcore for 24/7 usage?

Yeah there is only a few thousand miles of water :D

[naughty_guy]

what do you mean by 0.3? You mean +0.3 all each? But that'll put Vcore up to 1.825..

[sinn]

i think 3.2 is pretty much as high as u are gonna get that celery, i wouldnt be too dissapointed with it

[naughty_guy]

not saying that 3.2 is bad or wrong.. but i'm only @ 3.12, the title is not accurate.

[DazzXP]

yeah +0.3 fpr all however doing so means you may need better cooling 1.8v for a CPU makes it hot.

[naughty_guy]

doesn't 1.8V for a CPU kill it easily? the northwood sudden death?

[Tedinde]

ahh it's a celery, I slammed over 2v in one to get close to 3.7ghz once.

Dont give it that much volts though unless you can afford to kill it.

[naughty_guy]

truetrue... but what's safe for 24/7?

[ALT-F13]

Once I had Cel 2.4 (well, it was Intel Confidential and even before official release). It o/ced up to 3.66GHz on water (!) but performance... Well, we even published english version of our review in April, you may check it here: http://www.modlabs.net/index.php?location=articles&url=c2400

[Tedinde]

Celerons, Northowood core work great for encoding, That's why it's in my shuttle box, It has my TV card in it, and running F@H which doesnt care about cache.

They have their purpose if you just have your heart set on intel only.

Games take a beating bad though. about a 25-30% hit in 3dmark, clock for clock.

I was getting all my celery's from intel's IPD program, they always were like $60 for the top celeron chip whenever it came out. So i bought it.

Plus it's easy to sell one cranked @ 3ghz in a budget computer, Customers just see the mhz. But then most users base how fast a computer is on how fast programs open, or how fast the internet is on it!!!

Same as AMD's XP ratings, I gave up trying to explain them. And AMD is a better value and faster even though less mhz.

I just say it's a 2400+ or 3000+ processor.

[naughty_guy]

a bit off topic, but what's Intel's IPD prgram? Is it same as Confidential thingy??

Anyone have what they think are safe voltages for 24/7 to share?

[Tedinde]

Intel Product Developer, And theres a Intel reseller center.

If you have a business you can sign up. Get product demo chips at a really reduced price. Chips before they come out, MB,s servers, anything intel.

Tons of store literature, books, pamphlets, posters. Guidance mostly on how to sell intel. A lot of seminars if you want to go. Where to get you to go, they end up like If you come there will be a special priced 3.0c chip and a nice intel MB for $199. This was when the chip was over $350 the last one i went to in Philly "philadelphia".

I run mine @ 1.75v for the last 8 months in a shuttle Mini ATX rig. No problems. Im kinda not scared of losing a $60 2.2 celeron.

The SNDS as they call it. I have a 1.6a running F@H @ 2.82ghz @ 1.87V for since feb of 2003 running F@H 24/7. Watercooled.

I laugh at your SNDS!!!. Course i wouldnt do that 24/7 on a expensive chip!!! That i cant afford to lose or replace. So the choice is yours.

1.75 on a celeron isnt too bad.

[naughty_guy]

mm i agree on what you say, basically just matter of if you're willing to risk the voltage for that extra speed. thx guys

[sKiTz0]

Seeing as I know little about intel, I can't really say what your safe voltages are. Do keep in mind though, that this is your sisters computer. Dont get caught up trying to push it to the limit like you would your system, because its not yours. Its easy to do, I know from experience. Be very conservative on voltages and see how far you can go with that, and be satisfied. Your sister wont be running 3dmark I wouldnt imagine.

[naughty_guy]

oo i definitely should keep that in mind. I guess it's just me not satisfied with 3.12G from 2.4G. Thinkin backwards , that's already a 700mhz increase,compared to the time when I don't noe what's overclocking. :P

You're right bro

[STEvil]

Keep it about 3.12ghz, thats fine 8-)

1.7v agp is fine, and ram you can run 2.85 no problem.

[naughty_guy]

Cool.. Stevil, what would you say about 1.8V agp?

Also guys, does anyone when does a northwood core start to suffer from the SNDS? I've heard that it's over a certain voltage.

[STEvil]

I'd keep it at 1.7 if you can, 1.8 isnt really needed and could shorten the life span of something... or other.

[naughty_guy]

thx for your input stevil.. anyone know when does a northwood core start to suffer from the SNDS?

[naughty_guy]

anyone?

[naughty_guy]

anyone know when does a northwood core start to suffer from the SNDS?

[Kalway]

Generally over 1.75v... 1.85v for sure over that and you start getting hazardous... Northwoods are so much more voltage frail than Athlons that it frightens me. Good thing they put a heatspreader on them. I bet one slight chink on the core and it'd stop working.

[naughty_guy]

OOoo over 1.75? That makes me feel better, i thought it's like 1.675V.
