(RARE VINTAGE ES CPU) Intel Pentium MMX 233 MHz Q140 - Socket 7

Even more pointless in the fact they're all clock multiplier unlocked anyways.

An ES unlocked Pentium-III or Penium-4, now that'd be interesting.
 
ES == "I got it for free" == "it doesn't actually belong to me, it belongs to Intel" == "I'm not really supposed to sell it, since it doesn't really belong to me"

I'd say it's overpriced.

The problem is I got a "Not For Resale" DMHD-1000 (HD Radio Tuner) it was a promotional item given out by radio stations in 2007 or so touting the HD Radio advantage any way I think their is a time limit on how long that can be valid for. Also I don't think Intel cares much these days over a 25 year old CPU.

Well, they don't care. I was commenting on the price aspect. Get something for free, sell it for a gazillion dollars!!

Well they got it for free technically and Engineering Sample "ES" is still the property of Intel (or who ever made the sample item) I have never seen them actually want it back or even make an attempt to get it back why would they want a 25 year old CPU back now? maybe when it was a year or two old but now it is practically worthless (not in the eBay sellers eyes though!) Also don't the Engineering Sample parts contain flaws sometimes hence the name "Sample"? What is the advantge (if any) over an Engineering Sample Vs. a production part?

ES are make to "impress" (media coverage). So, might perform better, might OC better, etc. However, sometimes there will be flaws. Of course, sometimes, they are very close to what the product ends up being (yawn).

Not even the Extreme edition Pentium 4 CPUs were multiplier unlocked.

And why would you even want a multiplier unlocked Pentium 4? High FSB is what you want to use on those and you often have to lower the multiplier when doing high FSB overclocks.

don't really see how an unlocked multiplier would help on a Pentium 3 either. Just get a good board and a Tualatin 1.4Ghz 512KB cache CPU and go from there.

Two main reasons for me:
1. Multiplier unlocked gives you a lot more clock freq freedom.
2. For long-term stability purposes, you can run at default FSB speeds so you don't run non-standard AGP/PCI frequencies. Lots of these parts aren't readily replaceable anymore.

FSB overclocking forever!!!!

And with the FSB overclocking the whole system runs faster. And with FSB overclocking you generally run into a CPU limit before you run into an FSB limit... depending on the CPU, Pentium iii and iv included.

The only real use for an unlocked multiplier on those would be one with a lower default multiplier.

Oh yea, I was building a Win98 machine and was looking for an unlocked Coppermine/Tualatin. An unlocked multiplier goes a long way for clock down for the handful of some games that go too fast.

As far as FSB goes, AGP/PCI locks were not introduced until i875/i865 (IIRC), so not really keen on running vintage things out of spec for long duration.

Tell that to the Pentium 4 3.73Ghz. those generally go for $150 plus.

And you don't even want to know what a Cyrix 5x86-133 goes for.

Most expensive P4 would be the P4-3.4 Extreme S478. LGA-775 Pentium Extreme's aren't worth nearly as much because you'd typically want Core2's anyways.

The last Pentium 4 Extreme 3.73Ghz (LGA775) that sold on eBay went for $357 The only one on there now has a stupid asking price of $2,089
Found another... from China. Asking price is $599.

The last Pentium 4 Extreme 3.4Gghz (S478) that sold on eBay went for $250. There is a single one on eBay now for $500.

Prices are all over the place when they show up. I still want one of the 3.4Ghz ones and one of the 3.73Ghz ones for my collection.

I have a couple of the S478 Pentium 4 Extreme 3.2Ghz (S478). Pretty sure I picked these up for about $15 a piece from somebody that was selling 2 of them. One is in my PIAGP system (Industrial rackmount AGP/PCI/ISA with 14 slots).

Doubtful its sold. If you look at the eBay history, the same thing (Pentium Extreme 3.73) has literally been "sold" 3 times over by the same seller for the same price. It's likely some d-bag that is trying to pump the price.

These things are rare, but the demand is not very strong compared to their S478 counterparts for several reasons. From practical retro use perspective, LGA-775 is more suited for Core products; or if you must use a Netburst, you'd just opt for the Pentium Extreme 965 (basically dual 3.73's). From uniqueness perspective, the S478 Extreme's were made from the Gallatin (and big leap from Northwood/Prescott), but the S775 Extreme's are just the same Prescott-2M/Pressler CPU's, nothing special.

I mean, I'd like to have one, but not for anywhere close to that price.
