# Intel Xeon E5-2665 Server CPU: Intel Dem still dey call am intel xeon e5-2665, xeon e5-2665, e5-2665, xeon-e5-2665 Intel, Server CPU, Sandy Bridge Intel Xeon E5-2665 na Intel processor wey get 8 CPU core-dem and 16 thread-dem. ## Wetin you need know Intel Xeon E5-2665 na Intel processor wey get 8 CPU core-dem and 16 thread-dem. Reference specifications wey dem record no be tested performance or operating-system compatibility verdict. Verify di exact model and platform wit di manufacturer. ## Specifications Numbers wey dey below follow di Feex Hardware Database record for dis SKU. Fields wey no get recorded value dey omitted. ### Processor | Manufacturer | Intel | | --------------------- | ------------------------------ | | Family | Xeon E5 | | Architecture | Sandy Bridge | | Codename | Sandy Bridge EP | | Generation | Intel Xeon Processor E5 Family | | Manufacturing process | 32 nm | | Segment | Server | ### Cores and threads | CPU cores | 8 | | --------- | -- | | Threads | 16 | ### Clock speeds | Base frequency | 2.4 GHz | | ----------------------- | ------- | | Maximum turbo frequency | 3.1 GHz | ### Cache | L3 cache | 20 MB | | -------- | ----- | ### Memory | Supported types | DDR3 | | --------------- | ------ | | Maximum memory | 384 GB | | Memory channels | 4 | ### Package and power | Socket | FCLGA2011 | | -------------------- | ---------------------- | | Processor base power | 115 W | | PCIe | Revision 3.0, 40 lanes | ### Market Intel Xeon E5-2665 launch January 1, 2012. | Launch date | January 1, 2012 | | ----------- | --------------- | | Model | E5-2665 | ### Features Intel Xeon E5-2665 record 2 instruction set-dem for this sheet. | Instruction sets | [AVX](https://feex.it/wiki/l/pcm/hardware/system/avx/), [64-bit (x86-64)](https://feex.it/wiki/l/pcm/hardware/system/x86-64/) | | ---------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | | Virtualization | [Extended Page Tables (EPT)](https://feex.it/wiki/l/pcm/hardware/system/ept/), [VT-d (DMA Remapping)](https://feex.it/wiki/l/pcm/hardware/system/vt-d/), [VT-x (Hardware Virtualization)](https://feex.it/wiki/l/pcm/hardware/system/vt-x/) | ## Compatibility | Socket | FCLGA2011 | | ------ | ----------------------------------------------------------------------------------------------- | | Board | Shared socket no mean automatic compatibility. Check di motherboard CPU list and BIOS revision. | | Memory | DDR3, up to 384 GB | Shared socket no mean automatic compatibility. Boards dey often need BIOS update before newer chip wey dey di same socket go fit post. Cooler clearance, VRM quality, and power limits matter just like di socket name. Read di memory list on di board. Di CPU fit list more standards pass wetin one motherboard go accept. CPU wey no get integrated graphics no need discrete graphics card every time. Some server motherboards dey provide separate management graphics controller. Check di motherboard and CPU documentation. ## Manufacturer-checked specifications ### Intel Xeon E5-2665 Dem check these fields against Intel's model-specific reference on 2026-10-29.
