Intel Xeon E5-2643 v3, a 6 core, 12 thread LGA2011-3 processor at 3.40GHz with 3.70GHz turbo and 20MB cache, built for clock speed, refurbished.
The Xeon E5-2643 v3 is the frequency optimised six core of Intel's E5 v3 family, the Haswell generation for the LGA2011-3 socket. Its 3.40GHz base and 3.70GHz turbo are the highest of the generation, with 20MB of cache, DDR4 memory at 1866 MT/s, PCIe 3.0 and a 135W rating. It exists for software that runs on few threads and is licensed per core: databases, trading systems, CAD and simulation. Buyers in Qatar fit the refurbished 2643 v3 to 13th generation Dell servers, HPE Gen9 servers and Precision or Z series workstations of that platform when a fast clock matters more than core count. ServerDove keeps it in Doha stock for those licence sensitive and latency sensitive builds.
CPU-INTEL-E5-2643V3Specification
Twenty megabytes of cache on six cores is generous, and with the high clock it gives each thread more cache and more speed than any other v3 part.
The 135W rating is the cost of the clock: the same six cores in a mainstream part draw 85W, and the difference is spent on running every core a gigahertz faster. Cooling, not compatibility, is the thing to check before fitting it.
A database licensed per core runs on twelve licences across two of these processors and still has the fastest clocks in the generation. The same logic applies to engineering applications that use one or two threads. For virtualisation or batch work, the eight and fourteen core v3 and v4 parts give more throughput per socket.
Installation
No firmware update is needed on a v3 era server. The 135W rating is above what some 1U chassis support with the standard heatsink, so use the high performance heatsink where the vendor lists one and check the chassis processor wattage limit. Fit two identical 2643 v3 processors for a dual socket system, with DDR4 ECC Registered memory, which runs at 1866 MT/s with this processor.

Why buy refurbished
Enterprise hardware, tested in Doha, at a fraction of the price of new
Every unit we sell has already proven itself in a data centre. We test it again, grade it, and back it with a warranty before it leaves our stock.
Tested before it ships
POST, burn-in, memory and power-supply checks on every unit. Anything that fails is repaired or pulled from stock, not sold.
Same performance, lower cost
A Xeon runs the same workloads whether it is new or two years old. Spend the difference on more CPUs, memory or storage.
In stock, not on order
New enterprise hardware can take weeks or months to arrive. Ours is on the shelf in Doha and delivered across Qatar within a day.
Warranty and local support
Every unit is covered. Installation, configuration and hardware support are handled by our own team in Qatar, not a call centre abroad.
