and for example, let's say you had 2 quad core 6600s..one was non es, one was. the non was selling for 300 bucks..what would the es version be worth to you to buy? thanks!
THOUGHTS ON ES PROCESSORS?

much less obviously since it has no warranty. maybe 150-200 tops.
unless there is proof that it overclocks extremely well, in which case I would be willing to pay up to retail price.
never pay more than retail for one, unless you are getting a chip prior to release, in which case paying more is justified since nobody has one yet.

so i've read..but i bet review sites don't return em
actually, i know for fact a number of them don't return them..nor are they asked for them back kind of like cd's that we get from the record companies at our radio stations..they are the property of the record companies forever..but they never expect them back..it's just to avoid resale.

to OP: it depends. I have an X6800 ES which is a late stepping (it'a a B1, retail CPUs are B2 or higher). I would keep my hands off early steppings though since these ES might have non-functioning, deactivated or even missing features. For example, some Conroe ES have their EIST disabled (it works just fine on mine). So, if you didn't get your ES from Intel directly without any documentation (and chaces are basically ZERO
) it's quite a bit of a gamble. Also, early stepping ES could be very bad overclockers. What makes ES attractive is that most (yes, most, there's no guarantee) of them, regardless of their model number, come with unlocked multipliers.Personally, I would not pay more for an ES than for a retail CPU, especially if it's a high end CPU. JM5C.
more great info, thank you..and no i don't have one..but let's say i had an opportunity to get one..that would be worth it to me if the multis were unlocked..didn't think of that..but i suspect that to is a gamble..re: steppings..so let's say i know that it's a B1 stepping..is that the very very first stepping in the process or last stepping in ES..i'm pretty sure i have a B1 stepping e6400..and i'm sure there was B1 steppings before GO of the 6600 quad, right? so i'm a bit confused there by what you said great info though...
great info though...
There some false information here. Unlocked multipliers are a total rarity in ES chips. almost all ES chips are exact counterparts or the future retail version. Extreme chips are unlocked, others are not. I have seen E6300s, E6400s, E6600s, E6700s, E8400s, E8500s, X6800s, QX6700s, QX6850s, QX9650s, LGA775 Xeons both Dual and Quads, and so on. I have never seen a non extreme chip with unlocked multipliers, with the exception of one E6400. Completely random.
Secondly OP, there are many kinds of ES chips:
There are very early steppings, which in the Core 2 family were denominated B0. These chips are the ones used for early demonstrations at IDF. They lack almost all features, such as EIST, C1E, TM1 and TM2. These can be easily recognized since in the microcode they are marked as Genuine Intel CPU (R), and there is no model. The only way to "call it" is by finding out what the default multiplier is. You want to stay away from these, they were never meant to be used 24/7.
After these come B1. These chips are usually sent out to motherboard manufacturers for testing purposes. These chips are usually fully functional. The microcode is also marked correctly. Some of these chips go to reviewers for very early press previews, and they get sold for insane prices since they are functional pre-retail chips.
After these come B2/B3. These chips are identical to their retail counterparts in every way. These chips are sent out to reviewers just before the NDA is lifted for press reviews. These are the most common chips being sold as engineering samples, since they end up in the hands of reviewers that have no scruples in making a few extra dollars.
Lastly G0 engineering samples, which are identical to retail parts, were handed out to motherboard manufacturers for compatibility testing.

good point JAG87.
I haven't seen a locked ES myself and that includes the non-extremes, on the other hand I always focused on the extreme CPUs. I must admit I've recently heard lots of non-extreme ES owners say that their CPU is indeed locked. The guy I bought my X6800 from was selling an QX6850 ES as well and he told me that even though the Quad ES was unlocked he couldn't use all the multis on that CPU.

interesting stuff, gents...i was looking at the steppings on the Q9000 datasheet for kicks today and it seems to indicate the retail starting point on those at C0. i think it goes C1 , then M1 after that (sheet is updated as of feb 1st matter of fact) interesting as well that for all the talk of errata causing the delay on the the 9000 series but not affecting the qx9650, the only errata data that talks about causing a potentially unstable system is relative to the qx9650 but no mention of the 9450 and 9550. (eratta 51 for reference which shows fix beside it). so, i call bs on that story and wasn't sure i bought it in the first place.
now that you talk about locking unlocking, yeah, i only heard that prior in reference to the extreme quads now that i think about it.
my current 6400 is a B2, not B1 stepping by the way (was a retail processor bought in about june of 2006 so well after they were in the retail channel)

I can tell you that when we tested parts, any part, we usually beat the crap out of it. Retail components are almost always better, because those ES's are usually in short supply through the different testing cycles, and the same part almost always gets used for many different tests, and is shared by test engineers trying to get their work done.
