Engineering Samples

[Methanoid]

I was looking at buying an ES chip (yes I know they are not supposed to be sold but people still do!)

The seller said

"This item is Engineering Sample, whose specs is different from the non-ES ones." - really? I had no idea!!

"Engineering samples are the beta versions of integrated circuits that are meant to be used for compatibility qualification or as demonstrators. They are usually loaned to OEM manufacturers prior to the chips commercial release to allow product development or display. Usually, they are picked out of a very large batch and perform correctly. However, rarely they may have faults that were fixed in the production model."

Not heard of faulty ES chips but sounds to me awfully like someone with dodgy components to sell. I was asking if the chip supported VT-d!!

"So, we don't guarantee if it can be overclocked by changing the multiplier clock ratio." I asked. This IS OCUK after all. I hear most ES Xeons do not overclock now

Anyone shed any light?

So prob get a better result with a 6 core 5820K OC at 4ghz (maybe more?) than a 10 core at 2.4ghz?

Yes, I did note that with interest

@ALXAndy, my plan is running Linux as base, with VMs for Windows, Mac etc. But I doubt I will be needing Win/Mac/Linux ALL to have shedloads of CPU power at same time. So With a 6+6 core I could allow each 2+2 cores to each (3 monitors). Each VM will have its own KB & Mouse and graphics card passed through. So should get close to native performance on all machines.
