OK, if already got an PIII-750 & a Tualatin supportable mobo, would it be wise to upgrade to using a 1.2GHz Celeron or stick to using an PIII-1GHz or can afford, which I doubt so, an Tualatin PIII-1.12GHz?

I would go with a 1.2 tualatin CELERON. These babies overclock very nicely and 1.5 GHz isn't impossible and at a low cost... :)

1.2 Celeron,....cheap/highly overclockable, ol'man has his at 1600, and Pinky has his at 1500+....

Tually.. You'll be guaranteed to hit 1500 or maybe more :)

1400 with stock cooling.

Go with the 1.2GHz Celeron - mine is running 1656 air-cooled (SK-6 and 20CFM Sanyo Denki) at 1.675v.

I just ordered the new Swiftech MCXC370, so when that comes in I'm going to remove the IHS and shoot for 1700. :)

Whoa going for 1700.. Are you using the wire trick..?

BTW, I am still hesitant to sell away my PIII-750 for this Celery 1.2GHz. But do you guys still think its better to switch?

Spose you didn't know that aluminum doesn't conduct heat as well as copper huh. Yeah that core is small and aluminum doesn't cut it. How do I know; do you need to ask? O well we will have another saying that it isn't worth it to remove the IHS and in this case with aluminum being next to the core it won't be. If I were you HEMI I would leave the IHS on unless you plan on keeping copper next to the core. Not sure why all the roundups point out that aluminum is not the way to go anymore but people still insist on getting aluminum HS's.

Thermal conductivity of aluminum is half of what copper is. Thus saying that copper will pump out twice as much heat in the same amount of time that the aluminum HS will which is needed since the core of the celery is so small. I can tell you as I have told many others here once you remove the IHS you are dealing with a totally different intel creature. I would say it is closer to the core of a athlon for HS requirements in all aspects.

The reason is because you are pumping more amounts of heat in watts through a smaller surface area. At 1650MHz you are pushing like 50w but yet it is througha area about 2/3 the size of the cumine. I think at most the cumines would hit what 35~40w at most yet they have 1.3x the surface are that the .13u cores have. You must also rember that these core have 50% excess non working L2 cache baggage that does nothing.

Word of advice. Don't expect the thermal shutdown feature to work as well without the IHS. That means always make sure you have very good contact between the core and HS and always test the core at default vcore+speeds or lower to make sure you have the maximium amount of contact between the core and HS. If you don't you may/will be sorry. I do this in the bios by slightly pressing down on the HS and seeing what the internal temps do. It is surprising. Could have been my problem the whole time. Well in a nut shell those are the funs things you will encounter as you remove the IHS and try to cool it with a decent cooler that made the grade for the older OC'd PIII's but you are not dealing with that anymore.

As for the guy above that is wondering if this will be a better chip than his 750. Yeah since you are about doubling clock speed and IPC @ 1600MHz.

Ok, thxs. I see the SSE-2 isn't implemented on this newer Tualatin Celeron. but is it available on the Pentium III Tualatin?

This cheap has very excellent performance.. It beats all P3 before the Tualatin series.. Its not expensive.. best of all your going to squeeze 300-400 extra mhz out of it..

I really think its worth the money/
