ES Xeon Discussion

[Kneelbeforezod]

How do i find out the stepping of a particular Xeon ES? Do you you all email the seller and ask? Or can it be gleaned from the CPUZ Screenshot?

Typically they provide a cpuz screenshot in their sale. You can search ebay for "E5 v3 ES" and it will come up with quite a few. You can choose to search for QS instead of ES and it will give you later stepping cpu's closer to production releases.

any idea if these have any quirks? can you tell if it will support vt-d?

Anyone have any info on a E5-2649 V3?

 

[sal0]

Hi, I've researched a bit on xeon ES now basically understood that my price/perf/tdp sweetspot is around 8 and 12- core parts E5-2648L V3 and E5-2650L V3 for 130-180$.

I'm looking for QS which is Stepping 2, Rev M0 so it should be close to OEM cpus.
Ebay sellers don't seem to list true max turbo speed on these, only stating 1,8ghz and cpu-z 2,1ghz.

Are what I'm watching.

Can I trust on intel arch on 2,5 / 2,9 ghz turbo single core, or will it be a lot lower?

I'm on Asrock x99 extreme 4 stock bios so I shouldn't expect any compatibility issues?


Thanks for awesome thread on this.

Is QHZE Broadwell 2683 ES a good choice?

 

[b9creator]

Any thoughts/warnings about this processor? It's stepping zero of course...

I can still send it back if there is a better choice in this price range?

Workstation build...(not gaming)

Thanks!

managed to run my xeon @ 2.8ghz and 2.9ghz on full load...

Nice! How did you do this?

Nice! How did you do this?

I would assuming using the microcode exploit for V3 xeons...

I believe it was mentioned before in this very thread (at least I could have sworn that is how I found out about it), here you go:
What controls Turbo Core in Xeons?

Thanks @custom90gt - I wasn't going to read 70 pages to find a URL to a page in which I'm not sure of the specific page/url he was thinking of linking to.

Oh come on, where is your sense of adventure?

Is it likely that a Xeon E5 2630 V4 QK3G M0 stepping will work on an ASUS X99 board?

 

[dunde]

If you have a look in the thread you will discover that Asus is mostly a no go with ES. It might work with QS? Ask the seller for compatible boards. I run my E5 V4 on Asrock.

Hey Gents, has anyone had experience with the particular CPU/listing below?

Intel Xeon E5 1660 V4 ES 3.1GHz Max Turbo 3.3GHz 20MB 8 Core 140W B0 Processor | eBay

I'm looking to build a new architecture rig, mainly because it takes a few hours to render the example building included with Autodesk Revit on my 4770k CPU. Some folks and I are doing concepts for a video game we want to develop, I'm responsible for the buildings and architecture, general items and such, having such a CPU would benefit me.

My use case also involves gaming when not designing. Lots of Visio charts as well.

From what I have gathered (edit) -not- in this thread, B0 processors are janky and generally should avoid? C steppings are the ones to get, or M steppings?
