We will confirm compatibility within one business day. Even if you have met the terms of purchase, you must inform us in advance.
The reason for the above requirement is that a significant number of customers apply for a return after receiving the item without carefully reading the item description or not being able to distinguish between the product version, ES version or QS version, or if the item is not compatible with the customer's motherboard. This forces us to handle each item order very carefully, so the buyer is fully responsible for sold out items, shipping cancellations and shipping delays due to non-response to eBay Messages and late responses to eBay Messages.

Features and further details

The CPU-Z screenshots shows the Stepping, the Number of CPU cores, level 1 cache , level 2 cache and level 3 cache , Max TDP, multiplier, and the Core speed (the maximum frequency) which is the maximum ALL cores frequency at which the processor is capable of operating using Intel® Turbo Boost Technology (Turbo Boost all of the cores simultaneously). All of the engineering sample (ES) version of E5-2600 series CPUs are NOT UNLOCKED but will be able to turbo up ALL cores (Turbo Boost all of the cores simultaneously) to the maximum frequency which the CPU-Z screenshots uploaded shows.

Special Notice:

Intel's definition of Max Turbo Frequency in Intel's official site is "Max turbo frequency is the maximum SINGLE core frequency at which the processor is capable of operating using Intel® Turbo Boost Technology. " Therefore, the meaning of "Max Turbo Frequency" which shows on intel's official site, is different from the meaning of the Core speed (Turbo Boost all of the cores simultaneously) shows in the CPU-Z screenshots uploaded on this page. About Intel Turbo Boost, the Calculation of Intel Turbo Boost shows an Example on the middle of this page of this link.

About C6/C7 low-power states problem

If you are experiencing stability problems or worse, the system shut down completely. Because most power supplies do NOT support Haswell's C6/C7 low-power states, so If you are experiencing stability problems or worse, the system shut down completely, please disable C6/C7 power states, which will not affect the performance and will just affect the low-power sleep states.

According to an Intel document viewed by the gang at The Tech Report, Haswell’s C6/C7 states requires a minimum load of 0. 05 amps on the 12V2 line. Power supplies that are older or budget models simply aren’t capable of delivering such a small amount of juice. As a result, users with incompatible power supplies may experience stability problems or worse, the system may shut down completely if the power supply unit (PSU)'s under- or over-voltage protection kicks in.
