Edit: So in theory, a "real" Coppermine is made in 1133, but yes, it wasn't on the market for long, before it was withdrawn for stability issues, so probably not an easy find ..

In theory everything is possible. It is even possible that Intel produced them in the form of special orders for OEM parties.
But I have not yet come across a photo of a non-T 1.133Mhz Coppermine so 'theory' is fine by me 😀.
Do you have a source for the 'withdrawn for stability issues' report for s370 releases ?

Re backwards compatibility: according to the Wiki page they run on 'older' systems.

Unfortunately no sources for the "withdrawn" issue .. It was directly from the back of my mind 🤣

Over time I have come across different reports (often reports of reports of reports) on the web in which the 'Intel call back' issue was mentioned in relation with the 1.133Mhz edition in the widest sense but further research into the issue shows that there is really only hard info on the slot version.

And the only 1.133MHz stepping cC0 (year 2000) version that is listed in the Intel sheets is the SL4HH so my take is that there never was a FC-PGA version of this cpu released (and sorry for being tedious ;-0.

It's a Gateway OEM version of the Intel i815EEA motherboard, swapped into an older Slot 1 P3 Gateway case.

I hope that you will benchmark both the 1100/100 and the 1000/133 and report back here - I, for one, am curious after the difference.

Sure, I'll do some runs. My video card is a Diamond Viper V770 32MB so that might be a tiny bit of a bottleneck compared to a GeForce 256 or a Radeon but I should still be able to get some good results.

How about those benchmarks eh? Would love to see some 3D Mark 99 results

If you'd like to get an idea of how much a 133FSB Pentium outperforms a 100FSB version, take a look this link. It's for overclocking Celerons, but P3's up to 1Ghz/133 are compared:

Did that not long ago with a bunch of Slot1/S370 CPU's.
ASUS P3B-F for everything, and my trusty ol' ASUS V7100 GF2 MX.
GPU is a bottleneck of course but it scales pretty good I think.

Thanks for your work to 3DMark99 and 3DMark2000 benchmarks.

So i can compare the CPU 3DMark99 value of my maximum downclocked pentium 4 northwood.

My Pentium 4 @1160 : 3DMark99 CPU - 14924
(running with 55MHz FSB, DDR, i845 chipset)

Your P3 1000EB : 3DMark99 CPU - 14797
Your P3 1100E : 3DMark99 CPU - 15488

Here an impression from a couple of years ago of the missing 1.133HGz fsb 133 link:

This is an overclocked 850MHz of the last stepping and basically the same chip as a real 1.133GHz.
The benchmark was done on a Chaintech 6BJM s370 board with a Voodoo 3 2000 PCI. The Chaintech is just as fast as my ASUS P3B-F boards and if we consider the hardware configs comparable then the 1.133GHz fsb 133 is approximately 7.5% faster than the 1100MHz fsb 100 in your benchmark.

I was thinking this thread would be about Intels original Ill gotten super hyped pentium turbo frequency for Company approved overclocking of 66mhz FSB systems, turns out 2.x mhz overclock gets quickly forgotten

Thanks, that was exactly what I was after.

I was curious as I have a 800MHZ Slot 1 PIII @ 100 FSB. Looks like if I had a 133 FSB board I'd could get an extra 15fps in Quake III with the right setup!
