Intel Quad Core Q6600 ES (Engineering Sample) with Unlocked Multiplier

Is there such a thing and is it worth buying?
And if so what would be a max price tag?
Who flames you are usually the same arrogants, don't worry you're only asking for an advice.
Yes, early Q6600 ES samples were unlocked, but if I recall, they are all B3 stepping chips. Then, Intel no longer issued ES with unlocked multiplier. Now, if it is a good opportunity or not, it is a real lottery. The B3, ES or not, are really hot and need much volts. Some of them, were very good chips doing the 4GHz on air. An unlocked multi is definite plus, but not enough. If the seller can show you proof of OC potential (take care to have stable benches not screens), than why not. Otherwise, I won't get it for more than half the price of new one, as it is a B3 of very old generation.

Did not boot 4GHz at even 1.45V now! That's so bad compared to before, previously I benched Pi 32M at 4.050GHz with 1.392V idle many times, at least 12/13 runs of it and other stress benches.
Interesting. How long did you hold that chip and how much volts, including vPLL did you give it? If you let vPLL on AUTO, then maybe there's your issue toasting the CPU

I'm using my Q6600 at 475x8, 1.39v. Temps are about 50-56ºC loaded, ambients change a lot here (tropical country )

Here's a Screenshot with 18ºC ambients:
Many thanks. Yes, you really have a very clean WC rig, the cable arragement is impressive The big case suerely helps.

I also can do 51°C at 3.8GHz for a 20°C ambiant. 18°C is a nice temperature as there's an exponential relation between CPU temp and ambiant temp. In my tests, above 22°C, it is quite a x2.5 ratio
