Intel BLKD815EEA2 motherboard Socket 370 815EP 133 MHz 512 MB

SKU CH-ZC1K-2BPA2 MPN BLKD815EEA2

ATX board with Socket 370 for Celeron or Pentium III CPUs at 133 MHz FSB, Intel 815EP chipset, three PC133 SDRAM controllers supporting 512 MB maximum

  • CPU TypeATOM
  • Socket 370 supports Celeron and Pentium III CPUs
  • Intel 815EP chipset manages system logic
  • 133 MHz front-side bus enables fast data transfer
  • PC133 SDRAM memory standard supported
  • Up to 512 MB maximum installed memory

Socket 370 ATX board for legacy Intel builds

This motherboard uses the Intel 815EP chipset and a Socket 370 interface to support Intel Celeron and Pentium III processors. It accepts PC133 SDRAM up to a maximum of 512 MB across three memory controllers. The ATX form factor fits standard cases for period-correct system assembly or repair.

Passive chipset cooling and low component count

The 815EP northbridge runs without an active cooler, so system noise depends only on the CPU fan and case airflow. Power draw stays modest because the platform tops out at a 133 MHz front-side bus and 512 MB of memory. Typical builds remain cool and quiet with a basic chassis fan.

Replaces a failed or missing Socket 370 board

This unit restores operation to vintage ATX chassis that originally shipped with an 815EP-based motherboard. The jump is worth it when the original board has damaged capacitors, a cracked PCB or a dead chipset and the owner wants to keep the existing processor, memory and case. Builders who need more than 512 MB of RAM or a faster front-side bus cannot use this board.

Questions about this item

How is the Intel BLKD815EEA2 installed in an ATX case, and which alignment step is often missed?

Mount the ATX board using the standard nine-hole pattern, then align the I/O shield tabs with the rear cut-out before securing screws; the step often missed is seating the shield tabs fully so ports sit flush.

What maintenance or replacement will the Intel BLKD815EEA2 need over time?

The socket 370 CPU retention clip can fatigue after repeated cooler swaps, and the onboard coin-cell battery typically needs replacement every few years to keep CMOS settings.

What limit appears first on the Intel BLKD815EEA2 during sustained 133 MHz FSB loads?

The north bridge Intel 815EP chipset reaches its thermal ceiling before the 512 MB PC133 SDRAM limit becomes a bottleneck under continuous high bus activity.
