Where does M0 stepping stand? It's a 2666v3Generally you should look at the CPU-Z and HwInfo64 screenshots. QS or later ES usually have a Stepping 1 (CPU-Z) and HwInfo64 shows them as B0/M0/R0. First ES usually have Stepping 0 (CPU-Z) and HwInfo64 shows A0/A1/L0 stepping.
What about A1 stepping but ES2 option? I see a lot of cpus like that likeM0 should be a QS/OEM stepping or later ES. A0/A1/L0 is ES1 (early). So to summarize
ES1: A0/A1/L0 (CPU-Z Stepping 0)
ES2/QS/OEM: B0/M0/R0 (CPU-Z Stepping 1)
This is applicable for V4 Xeons. So ES2 and up have best compatibility and identical to retail/OEM steppings whereas ES1 is hit/miss with compatibility and features/clock speeds.

Its A1 but ES2... lost!
Its a Eeee 2698V4 I think. The QHUZ variant that are flooding ebay. Going for around 600$ I think or something like that.What is that processor model? Production/OEM processors should be B0/M0/R0 stepping. Anything such as A0/A1/L0 are still early engineering samples. I think that ES2 processor is still an early engineering sample as well as it doesn't have either B0/M0/R0 but it could also be a custom model too.
Not bad at all. Puts you on a modern chipset. Kinda wish I went this direction instead of 2670. I'd want a mix of compatibility and core speed. I don't really need MORE than than 8-10 cores. Motherboard I'd pickup is probably supermicro X10 DAX.For compatibility or for core count or for clock speed? My favorite at the moment from the V4 Xeons is the QK3G E5-2630 V4. It is an ES but with identical production stepping (R0) and has a low TDP of 85W while having a 2.2Ghz clock speed (3.0Ghz with turbo boost) all while having 10 cores and 20 threads.
Does this apply to Haswell v3sM0 should be a QS/OEM stepping or later ES. A0/A1/L0 is ES1 (early). So to summarize
ES1: A0/A1/L0 (CPU-Z Stepping 0)
ES2/QS/OEM: B0/M0/R0 (CPU-Z Stepping 1)
This is applicable for V4 Xeons. So ES2 and up have best compatibility and identical to retail/OEM steppings whereas ES1 is hit/miss with compatibility and features/clock speeds.
