Is Conroe E6700 ES B0 stepping new or old? Unlocked or locked?

[Manoj]

I can get a Conroe E6700 ES B0 Stepping. Just wondering if this is a new stepping or old one?

What is the difference between A1, B0, B1 and Stepping 5?

Are Conroe E6700 ES unlocked or locked? I am told that the Conroe E6700 ES is unlocked but the retail E6700 is locked.

B1 > All

[Manoj]

B1 > All

B1 is the latest?

So B0 is old?

I thought B0 = B1

B0 is pre sale version (ES)
B1 is retail version

[Fixxxer]

B1 is the latest ES and will be the first retail revision too.

[Manoj]

I am chatting with a local hardware reviewer and he tells me:

B2 = Multiplier Locked version (retail)
B1 = Media Sample
B0 = Pre-Sales version (unlocked multiplier 6x to 10x)

[jmax_oc]

Are B1 locked or unlocked like B0 ?

[Manoj]

Are B1 locked or unlocked like B0 ?

B1 = locked
B0 = unlocked

[Manoj]

Anyone here has a conroe ES B0 stepping and can confirm that they are unlocked?

[Manoj]

So much confusion about the stepping.

May be the new CPU-Z revision can solve all the confusion.

Wow, new CPU-Z version
Gotta get it.

[Manoj]

I don't know what's confusing about it.... B0/B1 (what most people have around here) are ES chips, B2 is production. B1 and above have locked multi's, I think because B1 was originally gonna be production but they need to fix something... hence B2.

What did they have to fix in B1 before making B2?

That means B0 also has the bug which didn't get fixed in B2.

B0 is unlocked, thats is on my E6700 ES

To conferm form my Intel rep contact

Oriental Dream is whom i am says:
B2 = Multiplier Locked
B1 = Media Sample online and mags
B0 = ES all stepping 4 & 5 unlocked multiplier 6 to 10

As has been said here already!

B0 is stepping 4 and B1 is stepping 5
there is also A1 stepping 1, the stepping 2 and 3 are intern to Intel

I've had all steppings/revision (with the expect of retail, of course). Here's how it breaks down:

So getting a B1 sample or B2 retail is better than B0 sample?

Since B1 = B2 (more or less)

B0 only has unlocked multipliers.

[eva2000]

B1 better oc'er

[fluffysheap]

B0 is old and is the same as stepping 4. It is stamped A4 on the chip but everything identifies it as B0. It's definitely old, at least a couple of months. This is what I have (it's a 6400) and although the BIOS options to unlock the multi are there and can be set, it won't POST if I increase the multi, even just from x8 to x9 (the same percentage increase works fine if I do it with the FSB). Maybe I just don't know what I'm doing but I haven't seen anyone overclocking their ES chips with the multi, just the FSB, even people whose CPUs can go faster but they have memory or northbridge problems holding them back. So I would not count on having unlocked multi on the ES chips except of course the XE which are also unlocked for retail.

Reading what FCG says above it looks like the ES chips have multiplier unlocked down only (set it anywhere from 6 to whatever it normally is) which, well, I've verified this works, but it's not of any use

Wish somebody knew what the B0/B1 bug was other than that it is minor. Intel said the FDIV bug on the original Pentium was minor and they ended up having to do a recall for it so I don't really know what "minor" means to them

[Manoj]

In that case I think I better just get the Conroe XE X6800 Stepping 5.

Conroe XE (ES) Stepping 5 is okay right?

Hell yes it is! These are shattering the records as we speak!

[WeedJunk]

But they are like killing your wallet instantly...

[Manoj]

But they are like killing your wallet instantly...

Yes, X6800 ES selling for above retail price now. No warranty, too.

[The Coolest]

With EIST you should be able to change multipliers down, just like on AMD's K8. Or am I wrong?

[PIRATA!]

So this 6700 "ES" is wat from?????

I don't understand why Intel has released this cpu.....

If someone can please explain please why aff all this, I will thank you very much.

ES is supposed to be a test CPU to show off Intel's performance. The chips can be crappy or really good. These aren't for sale... or atleast aren't supposed to be.
