It depends on the stepping of the ES chip - in the case of the 2650v3 there's an M0 stepping... and an M1 which is the same die as the production version.

- paulmd 9y agoIt does appear to be the M0 stepping based on the eBay auction. I don't suppose you have any place you can pull errata for stepping M0 so I can know what buttons not to push here? In CPU-Z I am getting something different from the seller's published CPU-Z screenshot - it's showing stepping "R2" ("retail"?) - however the name string is also still showing as "ES". I've attached a dump from CPU-Z that shows CPUID 0x0 and 0x1 values. From the processor value (0x000306F2) and the Intel data I could dig up - it would appear that this is actually the SR1Y1 stepping. Which is apparently the M1 stepping. Possibly actually a QS rather than ES. https://pastebin.com/2YnishGK https://pastebin.com/2YnishGK https://www.intel.com/content/dam/www/public/us/en/documents/specification-updates/xeon-e5-v3-spec-update.pdf https://www.intel.com/content/dam/www/public/us/en/documents... Not holding out hope overall given that it was sold as the M0 stepping but I guess you never know, maybe I got lucky. There was no pic on the eBay auction, and I would have to pull the cooler back off to check what's printed on the processor itself.
