MSI MS-7525 VER:1.0 (HP Boston Series OEM) Motherboard with Installed CPU – No RAM, No CPU Fan/Heatsink – Untested, Removed from a Working Computer Years Ago – LGA 775 Socket, Intel G31/P31 Chipset, MicroATX

Genuine MSI MS-7525 VER:1.0 (also labeled as HP "Boston" codename board, with revision markings like BOA:BOA, VER173, 21811472004173, ISI N, and HP-style "System Board" / spare part references) microATX motherboard. OEM board from Micro-Star (MSI) for HP / Compaq business desktops, most commonly HP Compaq dc5800 / dc5850 (or similar Compaq Presario / HP Pavilion models) from ~2008–2010.

Condition:Used – removed from a working computer years ago but unable to test since removal. CPU is installed in the LGA 775 socket (exact model unknown; common for this board: Intel Core 2 Duo, Pentium Dual-Core, or Celeron – e.g., E5200, E8400, E2180, E6550 with 800/1066 MHz FSB; thermal paste residue visible on IHS from photos). No RAM installed (four DDR2 DIMM slots empty). No CPU fan/heatsink included (socket retention bracket present, but no cooler attached – board will not run safely without one). No obvious physical damage to socket pins, capacitors, traces, or other components from photos, but due to age (15+ years) and long storage, sold strictly as-is with no guarantee it powers on, posts, or functions.

Quick Specs (Based on MSI/HP Documentation):

• Chipset: Intel G31 (Bearlake-G) Express + ICH7/ICH9 Southbridge
• CPU Socket: LGA 775 (Socket T) – supports Intel Core 2 Duo, Pentium Dual-Core, Celeron (FSB 800/1066/1333 MHz; BIOS-dependent, typical max E7xxx series)
• Memory: 4x 240-pin DDR2 DIMM slots (dual-channel, DDR2-667/800 MHz, up to 8GB max – no RAM included)
• Form Factor: MicroATX
• Expansion: 1x PCIe x16 (graphics), PCIe x1 slots, PCI slots, SATA ports, IDE
• Rear I/O: VGA (integrated Intel GMA 3100 graphics), PS/2, serial, parallel, multiple USB 2.0, RJ-45 Ethernet, HD audio jacks
• Graphics: Integrated Intel GMA 3100 (shared memory), plus discrete GPU support
• Other: Onboard audio/LAN (likely Realtek), standard HP front-panel headers

What's included:

• Motherboard only (as shown)
• Installed CPU (socketed, not removed/inspected beyond visual)
• Nothing else (no RAM, no CPU heatsink/fan, no I/O shield, no cables)

Ideal for:

• Harvesting a Core 2 Duo / Pentium CPU (supply your own cooler + DDR2 RAM to test/use)
• Repairing/upgrading old HP Compaq dc5800/dc5850 systems
• Retro budget builds or spares (Windows Vista/7 era)

Ships safely packaged with anti-static protection. Sold as-is, untested – no returns for functionality, CPU condition, or compatibility due to age and inability to test. Questions welcome – can provide closer photos of CPU area or markings if needed!
