Acer Socket Lga775 Pcie Motherboard 915m08g8ks Manual -
The Complete Guide to the Acer 915M08G8KS: LGA775, PCIe, and Where to Find the Manual
If you have landed on this page, you are likely holding onto a legacy Acer desktop—perhaps an Aspire T630, T650, or another mid-2000s model. Under the hood lies a critical component: the Acer Socket LGA775 PCIe Motherboard model 915M08G8KS.
Finding documentation for OEM (Original Equipment Manufacturer) boards like this is notoriously difficult. Unlike retail motherboards from ASUS or Gigabyte, Acer rarely hosted detailed manuals on their public site for long. This article serves as your complete resource. We will cover the motherboard’s specifications, its historical context, upgrade paths, BIOS settings, and—most importantly—how and where to find the 915M08G8KS manual.

3. Hardware Specifications (Inferred from the Manual)
While we are hunting for the official PDF, we can reconstruct the official specifications based on the actual board layout and Intel’s 915G reference design. The manual you seek will confirm these specs: Search: "915M08G8KS" site:vogons
| Feature | Specification | | :--- | :--- | | Form Factor | Micro-ATX (9.6" x 8.0" / 244mm x 203mm) | | CPU Socket | LGA775 | | Chipset | Intel 915G + ICH6 (or ICH6R) | | Front Side Bus | 533 MHz / 800 MHz | | Memory | 4 x DIMM slots, DDR2-400 (PC2-3200) or DDR2-533 (PC2-4200), max 4GB (though 32-bit Windows sees ~3.2GB) | | Integrated Graphics | Intel GMA 900 (DirectX 9.0) | | Expansion Slots | 1 x PCIe x16 (v1.0a), 1 x PCIe x1, 2 x PCI | | Storage | 1 x IDE (Ultra ATA-100 for 2 drives), 4 x SATA 1.5 Gbps (no AHCI, IDE mode only) | | Audio | Realtek ALC655 or ALC880 (6-channel / 8-channel HD Audio depending on revision) | | LAN | Realtek RTL8100C / RTL8110S (10/100 Mbps) | | Rear I/O | PS/2 Keyboard, PS/2 Mouse, Parallel Port, Serial Port, VGA, 4 x USB 2.0, LAN, 3 x Audio jacks |
Critical Warning from the manual: This board does not support SATA II (3.0 Gbps) or SATA III drives natively. If you install a modern SATA SSD, it will work but be throttled to SATA I speeds (150 MB/s). Also, the board lacks a floppy connector on many revisions.
2. RAM Limitations
- Only non-ECC, unbuffered DDR (not DDR2, not DDR3).
- Dual-channel mode: Install matched pairs in DIMM1+DIMM2 or DIMM3+DIMM4.
