I was thinking it'd be fun to pick up a Tualatin setup to play with and see if I can break some records. Looking around it seems there are Tualatin celerons with 100fsb and 256k L2 cache (10-14x multis), and Tualatin "PIII-S" versions with 133fsb and 512k L2 cache (8.5,9.5,&10.5x multis).

I've got an old P3 board that will run up to 150FSB, which would be like 2.1GHz on the 1.4 celeron tualatin, but is that possible?

What is the hot board/ram combo for P3 overclocking? I know they came in DDR, SDRAM, and even Rambus. I'm sure some modern PC3200 would be killer in a P3/DDR setup, and I've got some PC133 that will run at least 150 at CL3 and stock voltage. I know rambus was funky with P4's...figure it wasn't much better for OCing with P3's (yay PC800!).

Any advice from you guys who were benching Tualatins back in 2001 or so would be much appreciated!

See if you can find an Asus Tusl-2 motherboard and some Mushkin Rev 3+ sdram.

Only problem with Tualatins is that you need to see if your mobo is compatible with them. Not all where done according to the new (Universal) specs needed for the Tualatins to be run.

Check in your mobo site if a BIOS revision was released to make itcompatible.

I have a few Tualatin chips kicking around but it is not easy to find boards for them. Be sure that if you put a Tulatin chip into a non Tualatin capable board you will kill the chip. You can get a converter and use a normal socket 370 board with these chips though.

The Tualatin Pentium 3 S with 512kb and extended feature set will easily beat an Pentium 4 clock for clock and it measures up very well against the Athlon XP of the same MHz. It runs much cooler than XP and will have a much more stable 24/7 lifespan.

The Abit ST6 and the Gigabyte GA-6OXET boards work well with the Tualatin processor. They sport the robust and stable Intel i815 B-step chipset.

The Abit ST6 features RAID 0, 1, and 0+1. Bus Speeds 50-250 MHz (1MHz increments), VCore Range 1.1-2.0V (0.025V increments).

The GA-60XET board has 4X 168-pins DIMM SDRAM 512Mb PC133. Bus Speeds 66-200 MHz (1MHz increments), VCore Range 1.05-1.850V (0.025V increments).

There are DDR and RDR based boards for the Tualatin out there somewhere but damned hard to find.

As for a Taualtin with DDR I have one. Good one BTW, unfortunatly it's a dually, but you can try in Iwill site for another option. I have a DVD-266uR-N with dual Tualatin 1.26S chips and 1 GB of memory.....currently waiting to be put back into commision with some upgraded hardware and a new PSU to keep the power too two CPUs and and HIS Excalibur 9800Pro (with a 9800XT BIOS).

If you have a socket 370 mobo, you'll need to check to see if it will support Tualatins. If not, you can probably get an adaptor. I remember hearing about a few Tualatins that got up into the 1.7 to 1.75 gig range. Don't ever recall seeing any above 1.8 gig, but maybe with supercooling.

That's a rocking system though... Dothan has more in common with a Tully than a P4.

Amen! The P3 was a good cpu, tualatin was an awesome core and dothan/sonoma are also great. I'm loving my new pentium m.

I had a 1.2 Celeron and a 1.0A, the 1.2 got to around 1.4 and the 1.0A would run 1.5 at stock voltage. It's hard to get the fsb up too much cause much SDR can't maintain those speeds and since most of the boards didn't have pci lock, it was running way out of spec. My 1.0A is still my secondary pc tho

[funnyperson1]

The two consensus best boards are the Abit ST6 and the GA-60XET from Gigabyte. There were many a heated debate around these parts about which was the better board, the Gigabyte did have a 1/5 pci divider supposedly, but some said it didnt work. Either would do you well if you could find one.

I also had good luck with an Iwill Vx133u, it had my 1.1a up to 1.67 and that system was pretty fast for what it cost me, but eventually the lure of an even cheaper system with DDR lured me to the dark side.

I know ol'man had done some interesting experiments with extreme cooling and had screenies of tuallies at 1.7-1.8. I say go for it, should be interesting to see what happens.

[>HyperlogiK<]

what about i840 boards? they were fairly solid weren't they (dunno about oc options beyond pll mods though).

[JCLW]

i820 was a good choice too. There are a few people around running dual PIII-S chips on Asus P3C-D boards. Just remember that i820 only works well with Rambus - SDRAM is broken.

Tualatins typically top out at 1700~1800. I've got two Celeron 1200s running at 1600 (133FSB) around. Both are tB1 stepping.

Although I really don't remember anyone with good results on an i820 except for those with P3C-Ds or P3Cs. Also I wouldn't recommend it because its easy to find cheap SDRam that can do decent speeds, not so sure with RDRam.

Of course, the board you use for this project is going to be very much limited to what you can find. I see a decent amount of tualatin boards on ebay, probably with the TUV4X or the Soyo boards being a good bet.

If you could somehow get your hands on an ST6 or a Gigabyte GA-60XET that would be best imho.

I used to have a Gigabyte GA-6OXET board and a 1.26S server proc and I had some fun with it. The board didn't have a chipset supported 1/5 or 1/6 divisor because the i815 chipset wasn't designed to support them, but the board had some pll circuitry built into it to give you them. And it did work too. You could also run the memory asynchronously with the fsb too, which came in handy when running the 133 fsb P3's because it was extremely hard (and expensive) to find SDRAM that could run very high bus speeds. At one time I had pelted my P3S with a 120 watt pelt and watercooling and I managed to get it up to a little over 1700 MHz at around 181 fsb with 1.85v vcore on that P3S and it ran like a scalded dog for it's day. I ended up selling the board and proc a year ago to upgrade to a faster folding processor and board.

Its funny that out of thousands of cities in the US mine was used for an intel chip. This core was made in Aloha, OR intel plant... lots of cities in the area but they picked mine. Random, sorry, just had to comment.

[aNTiChRisT]

Pentium Pro's were way ahead of thier time.

Banias Pentium-M's (1mb Cache) Were _based_ on the P3
Dothan Pentium-M's (2mb Cache) are something else...

[dwschoon]

Is there any update to this thread? I have a tualatin celeron tb1 1300 folding stable at 135 FSB. CPUZ reports actual cpu speed at 1765. This chip will post over 1820, but the voltage required is too high for my taste and i think my ram is holding it back. Im using air cooling. Mobo is an abit be6-II 2.0 with a powerleap ip3/t adapter.

[funnyperson1]

I still have my 1.1a, and while I used to laud it for its amazing overclocking (1.67 ghz on air with generic ram), now I am amazed by its ability to run on minimal voltage. I have that chip but I am using the SK6+ on my AthlonXP and so all I had was a Pentium 1 cooler with a 7cfm fan. Of course the chip runs fine at stock speed and 1.2V with max load temps of 35C in a case with no other fans. Long live the tualatin, although for most that had these chips, their tually days have been long over as other better performing solutions popped up.

[freeagent]

I had a SOYO 7VBA133U, wich is still being manufactured, with my 933EB, the last intel i ever pwned. The board itself wasnt too bad, no vcore or vdimm, or timeing adjustments tho... but i was able to run at 160x7 with it, and i scribbled the bios at 168ish fsb :P i wish i still had my old screenies, i loved that system, it was my first taste of 1ghz+ heheh.

[dwschoon]

Ill see how high i can get it to boot windows and try to get a screen shot.

[JCLW]

My g/f uses my 1200 tB1 / TUSL2-C @133FSB, and my mom uses my 1200tB1 / P3B-F / Upgradeware slocket @133FSB. They still work fine for office/internet.
