Currently im thinking about CPU's:

- E5 1660 v3 8c16thr 2,9GHz and 3,2GHz Turbo mode, max multipler 30, this one has 35MB L3 Cache.
- E5 1660 v3 8c16thr 3,0GHz and 3,4GHz Turbo mode, max multipler 32, 20MB L3 Cache.
- E5 1680 v3 8c16thr 3,2GHz and 3,4GHz Turbo mode, max multipler 34, 20MB L3 Cache.
- E5 1680 v3 8c16thr 3,2GHz and 3,5GHz Turbo mode, this one cpu-z sees as Revision M0, max multipler 35

Any one is able to clarify if they are unlocked or locked for OC?
 
I've got a E5 1650V2, and I know for a fact that the all E5 16XX V1 and V2s have unlocked multipliers.

I've read that the same is true for the E5 16XX V3s.
 
That could be true, but havn't seen any evidences for that.

Sellers @ ebay and etc mostly says that they arent OC'able nad that's why im looking here for people who maybe got them or have had for testing...
 
The release 6/8 core E5 16xx have definitely been 100% unlocked for all 3 generations so far, some reports of the lowest end quad cores (1620 etc) being locked. You really can have your overclocked cake with ECC icing too! :)

Not sure how thorough the users are that failed, so very few people try that we have little to go on. LCC/MCC does not seem to be the issue either, since we have unlocked examples of both types.

Very happy E5-1680v2 owner here @4.5Ghz, really hoping to get my hot hands on a 12+ core unlocked haswell or broadwell someday.
 
I own the 1650v3 and it OCs just fine as long as you have X99 that supports Xeons. The ASRock WS board is a solid board to use and will allow 128GB of RAM using RDDIMMs.

Basically, all Xeon equivalent of E series CPUs will be unlocked if its a 16xx CPU but if their is a 16xx CPU that is not an E chip (like the 16xxv3 quad cores) it may or may not be unlocked.

Do unlocked 10+ core Haswells exist? My E5-2676 V3 ES would be insane if it were unlocked.

So the E5-1681v3 (10), E5-1686v3 (12), and E5-1691v3 (14) are multiplier-locked despite being in the single-socket 1600 series?

Those aren't really part of the equation because you might as well consider them to not exist. They are impossible to obtain at the moment and we only know that Intel made them because they were accidentally mentioned in a document. Lots of people on the internet drooling over them, but you won't be able to get your hands on one until they're obsolete. Any website you find advertising their availability is lying.

Special order CPU's only. Think Google, Facebook, MS and large data centers.

That and the fact that there's also an ARK detailing the 10c, 12c and 14c chips. Plus Intel releases a document detailing every model of Xeon at their announcement. Sometimes different ones show up, but these are mostly chips that contain very special thermal throttling properties.
 
I can imagine, but I'm still curious as to whether these unicorn chips might be unlocked.

Given #7 and #5 it seems like there's a good chance they'd be locked (lack of unlocked HEDT counterpart).

There is no ARK for them nor any announcements. Only show up in a few "product change notifications".

These "unicorn" chips are indeed unlocked...but completely unavailable.:(

What's your source on that? There is essentially zero information on these things on the internet, so I'm not sure how you found out.

If you start naming your sources, they stop being sources...;)

Suffice it to say I discussed these "unicorns" at length with someone who knows not long after the V3s were launched. At this point in time, however, these chips are unlikely to ever be seen in the wild.

I would hate to see the power draw of an unlocked, 14c chip.
Click to expand...

I'd love to see it...;)

The power delivery systems (up to 12 phase on some boards) can handle the power draw, as can the available water cooling systems. I say, bring'em on! The end user can decide exactly how much power he/she wishes to comsume (or can dissipate) and set the chip's clock speeds up accordingly.

It would be nice to have the freedom to do so...;)
 
With as cool as this 6 core V2 runs at 4.5Ghz and up to 1.43V (running +100 offset), it probably still will be fairly impressive for a V3 with more than double the cores. Probably not as high an overclock, but still...

A 14-core probably wouldn't match a 6-core for maximum overclock frequency, but I think it should still be able to hit 4 GHz.
 
here is some clear clarification.
Intel xeon E3 series = highier binned mainstream cpus = z series/ your skylake i5 to 17 6700k.
Intel xeon E5 1600 series = highier binned lga 2011-3/x99 socket can be used with your Rampage V etc.
The E5 2000 series is locked, but can be overclocked to 4ghz using bios autotune on the ASUS Z10PE-D8 WS

are the xeon ES chips that cost pennies worth touching?

Depends. If it is for a cheap server running light to medium workloads or for a desktop PC, sure. If you do plan to use the extra features Xeons have (virtualization, TXT, etc.) better buy an OEM chip.

Why overclock a Xeon? Seems like a waste.
Click to expand...

Why not? Sometimes they pop up for cheap compared to equivalent consumer processors and have extra instruction set features normal consumer processors don't have.

Also to note the Xeon models starting with 1xxx are all single slot cpu configurations for workstations and are unlocked and overclockable. Xeon models start with 2, 4, 6, 8xxx numbers are part of multi-cpu configuration and are not overclockable on its own (non-adjustable multiplier). These are usually binned with lower clocks and moderate turbo clock boost but have crap load of cores.

I MAY be wrong, good OC Cpu's have high leakage. Think Phenom II 42 TWKR, or on the GPU side, Gpu's with a lower ASIC seem to OC well.

Xeon's have low leakage so to get one for a high OC is counter productive.

Getting a Xeon for an average OC with lower voltage than typical seems to be the only reason to try.

Like I said, I may be wrong.
 
from my own experience......you couldn't be farther from correct. ;)They will always be as good..or better.
Mathew i believe is dead on correct
 
I don't use LN2, but from what I've read you DO want leaky voltage for extreme cooling and overclocking.
