I've got this board, yes it will take the Pentium III-S 1.4 GHz Tualatin with 133 MHz FSB 😀

Tualatin chips are a little bit taller, so coolers that worked on standard Coppermine chips, might put too much force on the socket clips. I've snapped them off on one board, that was a shame. So what I now do, is use a fairly tiny Socket 7 cooler, and just put a 120 mm fan on top. This works well on a test bench, but isn't a permanent solution. There are special Tutalatin coolers from Intel and other manufacturers.

You can try to modify the mechanism of how the cooler attaches, basically bend things, so the force isn't as strong.

I use a Celeron 1.0A on that board. (Bought both together new at the time. Running with the boxed cooler.)
The manual indeed doesn't mention Tualatin explicitly, neither and Tualatin CPU in the speed list. But in the "Performance List" benchmark values are given for "Intel New Pentium®III 1200 MHz Processor" / "Intel New Pentium® III Socket 370 Tualatin 1200 MHz". Besides, the whole point of that board is Tualatin support, starting from the 694T chipset (T is for Tualatin).

Thanks a lot guys. Very clear answers.

I also notice something and wanted to be clear on this also. As far as I understand, there are two versions of Tually CPUs: Modifed and unmodified.

- Are modified ones being modified to work with slot (with an adapter apparently) and normal socket 370 boards? (FC-PGA interface modification)

- I board like mine, which has native Tualatin support, does not need any modification since it is already FC-PGA2 capable, right?

- Is this extra thickness related to all Tualatins, or only the modified ones? From an ebay link:

"...Intel Tualatin Pentium-IIIs 1.4GHz(512K) include On-chip Socket Adapter!!! This CPU works perfectly on most of old P3 CPU Motherboard without other socket-adapter... 370-pin FC-PGA2 (modifie to FC-PGA interface)... This CPU was modified on backside of CPU... Caution : CPU height is ticker(1.1mm=0.0433inch) than original. You may need to adjust a tension of your heat-sink clip."

The extra thickness is only for those modified CPUs.

You do not need a modified CPU as your board has genuine Tualatin support (but a modified CPU would work).

Not true. The IHS adds height. So I recommend being careful with mounting CPU coolers. If you need a lot of force, you might snap of the hooks on the CPU socket.

Its true they are a bit thicker compared to CPUs without IHS but the 1.1mm extra thickness mentioned in the Ebay add is only for the modified CPUs 😀

I have never had any problem mounting even the modified CPUs but beeing careful is always a good idea.

Thanks a lot again, this is really helpful. Now it's time to acquire.

Strangely, there are Tualatin 1.4 CPUs ranging from 6.99 USD + shipment to 30 USD + shipment. I don't know if there is a real difference between different steppings, but will go for the cheapest at first. I'm at the moment trying to convince the seller from US, who is offering them for 6.99, that 45 USD shipment for a tiny CPU is way off. 🤣

...that 45 USD shipment for a tiny CPU is way off.

Good luck with that 😉

I'm also interested in buying a modded Tualatin since my socket 370 board doesn't support it,if later i'll get a board with Tualatin support will the modded 1 work in it?

Shipment is 10 USD now!.. 🤣 (no tracking, though)

As long as the board also supports Coppermine CPUs this should be true and I never heard of a board with only Tualatin support but I guess there could be some strange OEM board I never heard of 😀.

The mod makes the FC-PGA2 Tualatin a FC-PGA CPU just like the Coppermine, perhaps some voltage clamping is also added but for more technical information its better to ask the Korean dude as he seems happy to answer any questions.
