This article covers Intel インテル2.93ghzXeon X5570クワッドコア1333 8メガバイトL2キャッシュソケットLGA1366 slbf3.

Overview

The Intel Xeon X5570 is a server-grade processor from the Nehalem generation, launched in 2009. It features 4 cores and 8 threads, with a base clock of 2.93GHz and a max turbo frequency of 3.33GHz. Built on a 45nm process, it has a TDP of 95W, which was standard for server CPUs of its era. This CPU includes 8MB of L3 cache and a QuickPath Interconnect (QPI) speed of 6.4GT/s. It supports triple-channel DDR3-1333 memory, making it suitable for servers and workstations. Today, it is available cheaply on the secondhand market, making it an attractive option for budget home server or NAS builds. However, LGA1366 motherboards are no longer in production, so you will need to source used boards and DDR3 memory. Compatibility with modern operating systems and software is limited, so this is best suited for legacy or low-demand server environments.

Compatibility Guide

Socket: LGA1366. Compatible chipsets include Intel X58, 5500, 5520, and 7500 series. Memory: Triple-channel DDR3-800/1066/1333. Maximum capacity depends on the motherboard, typically 24GB to 48GB. Form factor: ATX and E-ATX are common for consumer X58 boards; server boards may use SSI CEB or EEB. PCIe: Version 2.0. Number of x16 slots varies by motherboard. * Power: Most motherboards require an EPS12V 8-pin CPU power connector. Recommended PSU wattage for a full system is 500W or more.

Product Info

The Intel Xeon X5570 was announced in March 2009 as part of the Nehalem-EP architecture. It has a TDP of 95W, a base clock of 2.93GHz, and a max turbo of 3.33GHz. It offers 4 cores, 8 threads, 8MB of L3 cache, and a QPI speed of 6.4GT/s. The manufacturing process is 45nm. Market positioning is entry to mid-range server/workstation, and it is now only available on the used market.

Best Use Cases

Budget Home Server / NAS Builder: Ideal for users who want to build a file server or media server on a tight budget. Pairing this CPU with a used X58 motherboard can cost just a few thousand yen. However, power consumption is higher than modern low-power CPUs, so consider electricity costs for 24/7 operation. Legacy Software Testing Environment: Suitable for running older operating systems like Windows 7 or Windows Server 2008 R2. If you need to replicate a Nehalem-era environment for software compatibility testing, this CPU is a good fit. * Light Virtualization Host: With 4 cores and 8 threads, it can handle a few lightweight virtual machines. However, it lacks modern virtualization features like AVX-512, so it is not suitable for heavy virtualization workloads.

Things to Consider

Motherboards are typically used, so check for capacitor wear and BIOS version compatibility. Memory is DDR3, which is not compatible with modern DDR4 or DDR5 systems. Not compatible with Windows 11. Windows 10 may work but is not officially supported. Single-thread performance is significantly lower than modern entry-level CPUs (e.g., Intel N100), making it unsuitable for daily desktop use. * Used units vary in quality and often come without warranty. Purchase from a reputable seller. ## FAQ
Q: Can I use this CPU with Windows 11? A: No. The Xeon X5570 does not support TPM 2.0 or Secure Boot, so it does not meet Windows 11 system requirements. It may run Windows 10, but without official support. Q: Which motherboards are recommended? A: Intel X58 chipset boards like the ASUS P6T or Gigabyte GA-EX58-UD5 are common choices. For server use, Supermicro X8 series boards are also an option. All are available used. Q: Can I use this CPU for gaming? A: Older games (pre-2010) may run, but modern titles will be severely CPU-limited. Additionally, PCIe 2.0 bandwidth will bottleneck modern GPUs.
