i just want to know f somebody out there already have done it. i have a tualatin celeron 1.3 and i overclocked it stably up to 1.73GHz @ 1.575 Vcore. i wanna know if its possible to run celeron 1.3GHz @ 2GHz by using pc150 sdrams like those of kingmax(or maybe a little over 150fsb, will 154fsb work?)...and how high should the vcore be? im planning to purchase pc150 sdrams, so i wanna know if it will work before i go on buying those rams. btw,m using abit st6-raid mobo (fsb can be selcted up to 250MHz, i think...)

thanx for the help!

Not likely. Most Celerons from 1.2GHz upward won't reach 133MHz FSB at reasonable voltages. You're just lucky it got that far.

ditto. Its not gonna be possible. The best ive seen is 1.6 - 1.7Ghz with liquid cooling according to OC databases.

aww shucks,i was hoping for a resounding 'YES', but then again...hehe thanx anyway guys! btw, i m not using watercooling on my system, just plain ol' air cooling with the help of my trusty cak4-88t! so does that mean im twice lucky? hehe...

*born to make a difference*

good lord, you put the massive copper Cak4-88t on that sucker? That's so overkill, but probably runs very cool even at low rpms

Instead of Rdram, why not just merge 4 Sdram channels...

by the way, i also got my celery working @ 1.63GHz on 1.425V, that's below Intel's default vcore specification which is 1.5V =)

wow. sounds like you have a extra special one there!

ok so it seems that everyone is very pessimistic with regards to the tualatin celeron's overclockability, hmm, i guess il just have to see it for myself then, ha...m gona buy those pc150 rams!!! hehe...ill come back as soon as i get sumthin out of it. (wish me luck?)

*born to make a difference*

haha you should put that money towards a new mobo processor and ddr ram instead

Treat your signature like a toothbrush: Don't let anyone else use it, and get a new one every few months.

1700~1750 is the tops for most recent Tualerons. Acording to the intel spec sheet vCore max is 1.75v, but lower is better.

what cooling system dya use for ur tualeron @ 1.74GHz? i got mine stable @ 1.75GHz using pc133 rams...i still havnt got my hands on those pc150 rams...

hmm, for a celeron running @ 1.74, i really do prefer a 1.74 running @ 145 fsb rather than a 1.74 with 134 fsb...

is it comparable to a p4 or athlon xp system running at a lower clock/frequency?

*born to make a difference*

Yeah, I've got some BGA PC150 to try when I get some time.

The higher FSB really helps.

In terms of raw processing power mine comes in around the same level as a P4 2.0 or an XP 1800+. Of course as soon as bandwidth comes into play it drops right back, but hey - not bad for a $50 processor.

For cooling I've got an old heatsink (& fan) off a Tbird-900. I've now lapped both the core and the heatsink and run 33/37C using AS3 as a TIM.

The chip I have in there now is a tB1 made in the 29th week of 2002. I've got a 32nd week tB1 to try as well.

What stepping is yours? What week was it made?

*Dual PIII-800 @900 i440BX and Tualeron 1.2 @1.74 i815*

i dont know the stepping, how can i know it? where can i find it? i also didn't took note of the date, all i know is its made in the philippines...sori, m just a newbie when it comes to overclocking...this is actually my first time =)

yeah! same here, when it comes to processing power, it surpasses the athlon xp 1700... talk about price/performance ratio, ehehehe...

*Dual PIII-800 @900 i440BX and Tualeron 1.2 @1.74 i815*

it says model B stepping 4 revision tB1...

i havnt yet dismantled my pc again so i still dunno what batch. what's the significance of knowing the batch?

*born to make a difference*

tB1 is the newer stepping (tA1) is the older one). I was guessing it was a tB1 when I saw the speeds you were hitting.

Some weeks overclock better then other weeks. In general it can be said that the later weeks overclock better then the earlier weeks - most likely because intel gets better at making them over time. I'm hoping my week 32 will run faster then my week 29 chip, or if not faster then the same speed at a lower voltage.

*Dual PIII-800 @900 i440BX and Tualeron 1.2 @1.74 i815*

Are all the tualerons sold today based on the tb1 stepping? so does that guarantee that a celeron 1300 can be easily overclocked to 1.73GHz?

ok, so m lookin at the celeron box and it says here:
pack date: 11/29/2002
fpo/batch # 7233a930
version # c10677-001
proudly made in the philippines, ehehe

so what do i look for f a want a newer/later celeron with the latest revision and can overclock more successfully?

hey, i rili do appreciate the help...
thanx!
