Is this an unreleased core 2 quad?

Hi There, first of thanks for the advice and help in advance.

I bought a used chip from a friend but it has no markings on it whatsoever..

We checked on cpu-z and it told me that it was a core 2 quad @ 3.2ghz with an FSB of 1600Mhz. The strange thing is the only processor i can find that matches these specs is a qx9770. Or could this chip be an ES? It doesn't come up as and engineering sample in cpu-z.

But here is the killer, this chip reports on cpu-z as E0 Stepping! so I am really stumped, can you please have a look and let me know exactly what it is that I have.

I have been searching and reading for the past 3 days solid now and cant get a definitive answer, I hope the community can help me out! :bounce: 

here is the link to the online validation

I think what you have there is an XEON 5482 which is part of the core 2 familiy is probably why CPU-Z see it as that.

I am a little confused how its running in a standard LGA 775 board but if it works it works.

Appreciate your response,

Hmm, is that socket 771? lol, i will have to count the pins.
Even though it comes up on cpu-z as yorkfield??
thanks again

Its the only Intel processor I could find that was E0 stepping that fits the description.

Happy Counting :lol: 

It should technically work in a 775 board I dont think the pin outs are too much different if they are different at all maybe a few extra grounds or something.

well, Cool, its got 775 pin spots, also I could have saved myself lots of squinting if i went here ! ahhah! Shows a 771 alongside a yorkie and it would have been so much more pleasure just to look for 4 extra pin landings! Link below, the chip I have is identical to the one on the right.

As i mentioned first off this thing is driving me nuts.. haha.

What mystifies me is the complete lack of any L3 cache.

Sorry, I don't have much experience with socket 775 systems but isn't the stock base clock supposed to be a lot lower than 400MHz?

Stock clock on these is 8x400 , and 3.2ghz as far as i can find out from intel.
I think i may have stumbled onto a Quad Core Extreme..

The Core 2 series never had any L3, and the 1600MHz FSB is normal for the QX9770 (and a few Xeons).

Is the multiplier locked or unlocked? The Extreme editions are unlocked. I think the engineering samples are also, but CPUZ usually shows that.

Hey Falcon yes the multiplier will accept any number, it is totally unlocked.

Everything points to a QX9770 but the last stepping for that was C1 unless Intel planned a E0 stepping of it and never fully released it and that would probably be why the CPUz name doesn't show up.

There are two E0 CPUs. A Q9650 and Q9550s(the s was for a 65w low power version of the Q9550). Maybe this is a QX9770s?

Download and run this:

Its Intels CPU identification tool. Might be able to give us the truth behind it.

Is it overclocked? It could be any E0 part with those multiplier and FSB settings in BIOS.

Even if it was overclocked, it would still be labled as a Q9650 or Q9550s due to is sSPEC number (like my Q6600 G0 is OCed to 3GHz but it still shows as a Q6600 G0 in CPUz, its sSPEC is SLACR).

Problem is as well, Intel has only released 2 official E0 parts the Q9650 and the Q9550s, and I am highly doubting they will release any more since 1. Core i7/i5/i3 are their main parts now and 2. 32nm is going to be ramped up this year for most FABs, so most FABs will be put into 32nm manufacturing.

If anything its as I said before, its is possibly a QX9770 that Intel had planned on releasing as a later stepping (E0) with improved thermals but when they did the Core i7 hit so it was pointless. Possibly some got out to the consumer end. If anything, the guy is super lucky if he paid a small price for it.

Sorry guys. Your a little late to the party on this one. We figured out that this is a C2Q Extreme 9770 a few days ago.
