Anyone OC'd a PIII Tualatin 1.4GHz?

[Pils]

Has anyone overclocked a Pentium III Tualatin 1.4GHz processor?

How fast can one reliably drive the processor, that is, to a speed at which an average 1.4GHz Tualatin would run stabily? Might one hope for a 150MHz FSB?

I'm considering running the processor on an ASUS TUSL2-C with Mushkin CAS2 SDRAM, and cooling the processor with an OCZ Goliath 2 SE heatsink/fan. Any other suggestions?

(For any wondering why I would do this, it is just that I love old technology implemented well, and the Tualatin 1.4GHz is the crowning achievement of the PIII era.)

Thanks in advance!

150 FSB should not be a problem. The limit of the Tually is ~ 1.7 GHz or so at the high end.

Thanks! Good to know.

Keep raising the fsb by 1MHz increments and if the computer crashes or reboots than raise the core voltage by .025 volts until stable. You should be able to get to the 163MHz bus at 1.650 volts which is a 23% increase and give you 1712GHz. Good luck.

From my experience, I'd say 150FSB is almost guaranteed. I've got four PIII-S 1.4s and they'll all run 150FSB on my Abit ST6s and my Tusl2-Cs. They typically need around 1.55V to run stable (default is 1.45V). In my PIII test rig I use 512MB of Mushkin Rev3+. My HS is the Thermalright SLK-800 with a 80mm Panaflo L1A. I haven't tried higher than 150FSB because I'm concerned about running the PCI/AGP too far out of spec.

I highly recommend that you use the SLK-800 or the SK-7 heatsinks. They're the best performing Socket 370 heatsinks you can buy. I think SVC sells the SK-7 for $20-25, the SLK-800 is $35.

Jeez, you took the words right out of my mouth! I absolutely love these PIII-S's! (and the Tualatin Celerons aren't anything to sneeze at either, especially for $40!) What a great CPU this is. Too bad Intel got caught up in the "Mhz Race" and abandoned the wonderful 512K PIII-S for the inefficient, Hi-Mhz P4 line. It's still pretty easy to find the CPUs for sale but have you tried finding a decent i815 Socket 370 board during the last six months? The best ones (Tusl2-C, ST6, GA60-XET) are all out of production, replaced by the endless cycle of Socket 478 clones. There's nothing out there except a few second-tier 815 products and some 694T Via boards. What a pisser. Oh well, I've bought myself a handful of CPUs (including a PIII-S engineering sample) and a few MoBos. I'll just hide away in my house with this wonderful "old" technology and let the world pass me by. In the meantime I've go a really fast, powerful processor that runs real cool and quiet. I can live with that just fine, for now.

Awesome... Didn't think that anyone would buy a P3/Celery Tualatins. I'm thinking of getting a Tualatin Celery myself and upping the FSB to 133 (default is 100). It's more than enuf for normal use

Neway, to answer your question, get over here and look for more success stories of OCing.

Good luck!

I had a PIII-S 1.26 on a GA6OXET overclocked to 1.5 GHz. I could have gone higher, but 160 FSB was as far as I wanted to push my PCI bus (40MHz). It is pretty hard to find decent mobos now. One of the kids rigs is a Tually 1.4 in a SOYO TISU. Not a bad board I guess. Its cheap and is one of the few 815EP's still around.

I, too, like these older chips. I still have 3 Tualatin Celerons (have owned many more which I've sold or traded). Motherboard-wise I only have one functional unit , an Abit VH6T. However, I got a SlotT adaptor (that I have yet to try) to use in an older board. I also have an Asus TUSL-C board that will POST about 1 out of 20 times (but runs fine when it does) and a Shuttle AV18ET that is very unstable at anything over 66MHz FSB (and not totally stable even at 66). The board got scratched really badly next to the socket from a screwdriver. It will POST every time, however

My CellyT 1.3 runs at a 112 FSB just fine.. my tv capture card can't take the PCI bus speed reliably until I back it down to around 109 or 108.
