I pulled up that ES means Engineering Sample.

In Wikipedia it says that this is a beta chip and that ES Chips are usually desirable.

Is this what I see in the FS: threads as Extra Spicy?

And what does this really mean to me?
 
ES does not always mean better. Especially if the chip has been through a stepping change. Each chip is linked to a specific engineer, they are not allowed to sell them. If Intel gets a hold of the serial number and traces the chip back to the engineer that let it leave their possession, then bye-bye job. And I supposed they could confiscate the chip, as it's Intel property... thus not allowed to be sold.

That's why they're usually listed as Extra Spicy
 
Hrm, maybe I should in fact pop out 4 Gigs of ram to see how far this puppy will go.
 
ES used to mean greatness, not so much anymore these days.. I have an ES E8600 that is a pig for voltage, needing more then most C0's :D
 
I think it is interesting that your chip does not show ES in CPUZ only in CoreTemp. I have two ES chips and they are both identified as ES in CPUZ.
 
Well I do have the HT [enable/disable] option, but the i5 doesn't have hyperthreading right?

The box it came in says i5 750. :shrug:
 
Yeah I downloaded the lastest version.

Does everyone with an i5 750 also have a option to enable/disable HT?

No, i5 750s do not have HT. If CPU-Z doesn't say it's an ES, the odds are good it's a retail chip and CoreTemp is wrong. I've seen retail i7 chips that are identified as "ES" chips in CoreTemp.

Update: I didn't have the latest version of Coretemp. After I updated it no longer said ES.

As for the HT portion, I don't understand why MOBOs give you this option even if the chip doesn't support it. AND what happens if you enable it.

"If you enable HT on a i5 maybe you can travel backwards in time."
 
very stable setup
