tualatin core celeron

[saimike]

hi guys,

i have a abit bf6 and i'm upgrading my cpu. yay. abit's webpage says that their latest bios will "Support Intel PIII/Celeron up to 1.1G(100) CPU. (Please mention: This board does not support Tualatin core P!!!/Celeron processors.)"

so my question is, what is the fastest non-tualatin core celeron i can pop onto my mobo? and how fast can i overclock it (its never fast enough *grin*)? thanks!

mike

The fastest Coppermine Celeron is 1.1 GHz. You'd probably be better off to get something like an 800 or 850 and overclock it.

 

[Richardito]

If you are lucky and pump a lot of volts to the core you could get a Celeron II chip overclocked to about 1.1GHz realistically. Maybe up to 1.2GHz if you are real lucky.

 

[saimike]

guys,

why is it a better idea to oc a 800/850 celeron rather than a 1ghz/1.1ghz celeron ... since their all coppermine/non-tualatin and my bf6 will accept it?

also, where's a gd place to pick up good oc-able celerons?

thanks!

I just saw how someone got a cel-t to work on a BF6 no problem. I think he hit 1500MHz. Here is the link and quote.



<< Yippie!!! My BF6 + C.1.0A works after all! . I tried it today again, and it just booted.
And the Vcore on first boot was again 2.05V!!! just like with my friends C1.2. No matter if i set 1.5V on one of my adapters i`t is always 2.05V on the first boot.
The CPU runs at 1500Mhz with 1.60 Volt. (2-2-2; ioqd@8, AGP@100Mhz) , it`s so fast, it`s a dream!!
(I upgraded from P2-350@480) >>



cel-t1.0a @ 1.5GHz on ABIT BF6

Worth checking out since you get a PIII at 1500MHz essentially for a little over $70.

The 1Ghz Celerons based on the coppermine core are already near or at their physical limits.
Overclocking probably wouldn't be that successful.

hi there, thanks for ur reply.

i remember reading a overclocking database (anyone know the url?) where ppl posted their cpu and what they're oc'd to. on it, 800-850's tend to hit 1-1.2 on the avg. i dont seem to remember what the 1ghz celeries did, but i'm sure they should be able to hit 1.1-1.2? this is my reasoning: if i buy a 1ghz celery i hit 1ghz _without_ trying and can get higher speeds without taxing the fsb (i have 1 pc100 and 1 pc133 sdram).

i'm quite a bit behind cpu tech since i bought this celery 366 (running at 555 now), but do i need a new slotket? where're the popular places to pick up a cpu (and slotkey if i need 1)? thanks again fellas!

Buy a p3 1000e and overclock it to 133... thats almost guaranteed. Problem is theyve gotten kinda rare.

The coppermine cores top out at 1.13Ghz don't they? Isn't that why Intel had so many
problems with their coppermine P3's at 1.13Ghz?

Thats ancient history. The early steppings had trouble @ 1.13. There have been many new steppings released since then. That speed is easy to do now.

 

[boyRacer]

Yup... look at me. 1.33 with no problems. Too bad its not fast enough compared to the rest of you running 1900s and NWs... oh well... its not like counter-strike needs a 2ghz computer.

Hmm I guess I haven't been following closely enough. I thought all 1.13+ chips were based on
the Tualatin core. OH well.

I have a coppermine based celeron 900 at 1.2ghz that works fine, rock stable.

I'd say get the celeron 900. Im pretty sure that starting w/ 900mhz, all celerons were based on the cD0 stepping, wheres the 800 and 850 both came in the cC0 and cD0 flavors.

 

[rogue1979]

Bang for the buck for a non-Tualatin goes for an overclocked 800-900MHz Celeron. The 800 is the surest overclock, they are all cDO now and always hit a 133MHz fsb for 1066MHz. The 850 or 900 overclocks very well too, but sometimes they won't hit the 133MHz fsb mark. CDO Celerons get suprisingly close to P3 performance when you get the fsb up to 133MHz+.

I am curious about the advice to overclock a lower-speed Celeron. I would think that the faster Celerons, while perhaps getting a lower percentage speed increase, would still overclock higher than the lower-speed ones. Even if they only win by a little, given the price differential I would think the higher speed Celerons would be the better option. Compare Newegg's prices:

Celeron 900 Retail - $64 shipped
Celeron 1100 Retail - $67 shipped

According to the Overclockers.com database, the average overclocks for various Celerons are:

Celeron 800 - 1128
Celeron 900 - 1179
Celeron 1000 - 1256
Celeron 1100 - 1309

Is there a flaw in this logic?

 

[MilkPowderR]

Yes, Boyracer is right.
saimike, if you can manage to find the P3 1000E cD0 SL5QV(Boyracer and I have em ), you will have the fastest P3 on your Abit BF6 mobo for the record. No other celermines will beat it no matter what they are oc'ed to. 1000E cD0@ 1333 is easy. 1400+ is possible. Mine's running at 1450mhz on an Abit BE6-2 mobo. Performs nearly as good as the Athlon XP 1700s with DDR setup. And I ran the bench comparison between this P3 and my Athlon T-bird 1.4 oc'ed@ 1575mhz(150fsb w/fastest ram timing) on a KT133a chipset mobo. This P3 literally destroyed my T-bird in 3D games and 3DMark 2000/2001. DDR on the Athlon would be very different story.

Well if you go w/ the 800/850/900, you might be able to overclock w/ a higher FSB than starting w/ the higher clocked celerons. The FSB does become a bottleneck at times.

Woah, this thread has come back from the dead.

 

[rogue1979]

I would definately give up a 100-150MHz of cpu speed to get a higher fsb with a socket 370 set up since it is so memory bandwidth limited.

MilkPowderR, the cDO P3 is an awesome cpu, but it still costs more than a Celeron 1.0a and a motherboard combined. Plus the Tualatin has data prefetch, uses less power, runs cooler and hits 1400MHz with little effort. Are you sure about those benches? My wife's Celeron 1.0a@1430MHz rocks, but even if I turn my Thunderbird down to the same speed, it beats the Tualatin by a considerable margin. I believe this is because of the Athlons DDR bandwidth and the muscular 128k of L1 cache vs 32k for the Pentium or Tualatin. I could be wrong, but I would assume a Thunderbird on a KT133a chipset would be about dead even with a socket 370 set up of the same speed. My kids Duron 750@1008 running on a KT133 non a chipset on a 112MHz fsb (150MHz Sdram) has more memory bandwidth than the Celeron 1.0a on a 143MHz fsb 815EPT chipset.

 

[Auric]

I compared the Coppermine and Tualatin 1100 256k's at default freqs and the latter outperformed by 12% on 3DMark 2001. And as said, all the while running cooler and at lower power for less than half the cost. Also, while they do whoop everything else on the CPU & FPU benchmarks they are not faster overall when including the chipset and memory, particularly in gaming. If you wanna keep what you have with no fuss and no muss then the P3 Coppermine is great but expensive. If you want the best bizang for the bizuck and like messin' then do the pin mod with C Tualatin. If it doesn't work or you destroy the mobo then you can always resign youself to a new FCPGA2 mobo and still come out ahead (just don't destroy the CPU).

 

[saimike]

wow, this thread really came back from the dead

just a quick update on what i decided on: 1.1ghz coppermine celeron ... newegg had the retail version for $67 and free s/h. so why deal with a slower celeron i figure, afterall they arent a lot cheaper. fwiw, its a sl5xr.

todate, i havent decided on a proper hsf yet, but the intel hsf lets me do 112fsb@1.9v without problems. i've been able to get it up to 117fsb and benchmark it with sandra (3443/1742 cpu arithmetric) but it is not stable, and UT crashes the system in less than 10min. i'm doing cpu burn-in with max heat generation now and that brings the temps to 35 deg celsius max so far with an avg of 31-32 most of the time.

btw, i'm using hardware sensors monitor ver 4.4.0.4.1 pro by alexander berezkin, and see 3 temps: mainboard, cpu1 and cpu2. where r they measured? somehow the abit hardware doctor doesnt want to run -- complains of some dll or smth and refuses to run.

anyone with ideas on how high vcore should get without long term (1-2yr) problems? i was running my c366@555 at 2.2v for over 2yr without problems.

 

[Richardito]

Those Celerons are known to run at about 1.9-2.0v with no problems, you'll probably squeeze out the last MHz's by that stage.
