The Mac Pro 'Eight Core' 2.8 (Early 2008) is powered by two 2.8 GHz Quad Core 45-nm Intel Xeon E5462 (Harpertown/Penryn) processors with 12 MB of level 2 cache per processor (each pair of cores shares 6 MB), a 128-bit SSE4 SIMD vector engine, and 1.6 GHz '64-bit dual independent frontside buses.' Via custom configuration, this model could be equipped with a single 2.8 GHz Quad Core Xeon E5462 processor, two 3 GHz Quad Core Xeon E5472 processors, or two 3.2 GHz Quad Core Xeon X5482 processors.
By default, it was configured with 2 GB of 800 MHz DDR2 EEC 'fully-buffered' FB-DIMM memory, a 320 GB (7200 RPM, 8 MB cache) 3Gb/s Serial ATA hard drive, a double-layer 16X 'SuperDrive', and an ATI Radeon HD 2600 XT graphics processor with 256 MB of GDDR3 memory and two dual-link DVI ports.
Expansion includes two external 5.25' 'optical' bays (one free by default), four internal 3.5' 'cable-free, direct attach' hard drive bays (three free by default), two PCIe x4 slots, and two PCIe 2.0 x16 slots (one free with one graphics card installed). Ports include dual Gigabit Ethernet, five USB 2.0 ports, two Firewire '400' ports, two Firewire '800' ports, and optical digital audio in/out, among others. Bluetooth 2.0+EDR is standard, AirPort Extreme (802.11g/n) and a modem are optional.
Compared to the original Mac Pro that it replaced, the Mac Pro 'Eight Core' 2.8 uses a more advanced architecture with faster and more efficient processors with larger level 2 caches, a more advanced vector engine, faster frontside buses (1.6 GHz instead of 1.33 GHz), faster memory (800 MHz instead of 667 MHz), support for optional faster Serial Attached SCSI drives (with the installation of the Mac Pro RAID card), and two 16-lane PCIe 2.0 slots.

- Disconnect the rear fan cable from the logic board.
- Using a long-handled, magnetized #1 Phillips screwdriver, loosen the four captive screws that mount the memory cage to the logic board.
- Rotate the computer so that it is standing vertically. Using a magnetized short-handled or right-angled jeweler’s #1 Phillips screwdriver, carefully remove the two short screws that mount the memory cage to the bottom panel of the enclosure.
- Note: To remove the memory cage and fan, you must first slide the fan partway into the cage. The fan is held in place by three latches, which you must release before sliding the fan.
- Using your forefinger, reach below the fan and release the latch nearest the logic board.
- Using a flat-blade screwdriver, release the two latches nearest the front of the computer.
- Slide the rear fan into the memory cage.
- Slide the memory cage and fan toward the power supply far enough that the cage clears the bottom edge of the enclosure. Then lift the memory cage and fan out of the enclosure.
- Replacement Note: If you are installing a new fan in the memory cage assembly, rotate the fan into the cage as illustrated. Also note carefully the orientaton of the fan in relation to the cage.
- Important: Before you install the cage in the enclosure, the fan should always be inserted partway into the cage.
- Replacement Note: Before installing the memory cage and fan, make sure all logic board cables below the cage are out of the way so that the cage sits properly and the cables are not pinched or damaged when you tighten the screws.
- Replacement Note: To install the memory cage and fan, maneuver the cage into position in the enclosure. Tighten at least two of the captive mounting screws. Then slide the fan toward the back panel, until you hear it snap into place.
- This procedure applies to 2.8 GHz and 3.0 GHz configurations of the Mac Pro (Early 2008). For the 3.2 GHz configuration, see the notes that mention “Processors, 3.2 GHz.”
- The steps in this procedure illustrate how to remove the lower processor (CPU B). The instructions are the same for removing the upper processor (CPU A).
- Every time you remove a processor, you must replace the thermal grease on the processor heatsink. New grease and alcohol wipes for removing the previous grease are included with replacement processors. Instructions for applying the grease are included with the processor heatsinks procedure.
- Disconnect the 2-pin cable for the upper processor (CPU A) heatsink from the logic board.
- Using a long-handled, magnetized 3 mm flathead hex screwdriver, loosen the four captive mounting screws for the upper processor heatsink in the order indicated below.
- Lift the heatsink straight up and out of the enclosure.
- Disconnect the cable connector for the lower processor (CPU B) heatsink.
- Using a long-handled, magnetized 3 mm flathead hex screwdriver, loosen the four captive mounting screws for the lower processor heatsink in the order indicated below.
- Carefully tilt the heatsink so that it clears the bottom lip of the enclosure and then lift the heatsink out of the computer.
- Perform the following steps once you have installed the new processors and ready to re-install the heatsinks.
- Preparing an EXISTING Heatsink for Re-installation. If you have a new heatsink, follow the NEW Heatsink procedure.
- Using the alcohol pad included with the logic board or processor replacement part, clean off any used thermal grease from the processor and the bottom of the heatsink.
- Using the thermal grease included with the logic board or processor replacement part, apply one dot of fresh grease to the raised square area on the bottom of the heatsink.
- Spread the grease evenly across the square to a thickness of approximately 1 mm.
- Warning: Do not apply more grease than recommended. The grease must not overflow the heatsink and come in contact with the processor connector.
- Perform the following steps once you have installed the new processors and ready to re-install the heatsinks.
- Preparing a New Heatsink for Re-installation. If you have a existing heatsink, follow the EXISTING Heatsink procedure.
- Apply the top gasket included in the parts box to the top of the heatsink.
- If you are replacing the lower processor heatsink with a new heatsink, install the bumper included in the parts box on the side of the heatsink.
- Do not apply thermal grease to a new heatsink. It comes with thermal grease already in place, covered by a cap over the bottom of the heatsink. Before installation, remove the cap.
- The Mac Pro (Early 2008 Dual 3.2 GHz) computer uses a special coating on the processor heatsink and processor to manage the temperature in the computer. The silver-colored coating comes applied to the underside of the heatsink and the top of the processor.
- Use the following guidelines when handling the processor heatsink and/or processor:
- Wear disposable nitrile or latex gloves
- Avoid touching the silver-colored coating on the underside of the heatsink and the top of the processor.
- Always make a visual inspection of new or existing heatsinks and processors before installing them in the computer.
- When removing or replacing the heatsink and/or processor, do not allow the heatsink to be separated from the processor for more than 30 minutes. The special coating on the heatsink and processor degrades with exposure to air; more than 30 minutes exposure could result in damage to the computer and a repeat, multi-part repair.
- Before installing a new or existing heatsink, check that the gasket that surrounds the silver colored coating on the underside of the heatsink is in good condition, as shown in the graphic. Replace the gasket if it shows obvious damage, such as cracks, folds, and broken-off surfaces, or if it is dislocated from the heatsink.
- The gasket is available through GSX as part of the Mac Pro Grease Kit, part number 076-1258.
- Release the latch on the metal processor holder.
- You may want to use a flat-blade screwdriver to help release the latches.
- Rotate the top of the holder to the open position.
- Lift the processor out of the holder.
- Important: When removing or installing a processor, always hold the processor by the edges. Be extremely careful not to touch the gold pins on the bottom of the processor, as this type of connector is very sensitive to contamination. Also be careful not to touch the gold pins in the processor socket on the logic board.
- You can identify the processor by the speed etched on the processor. You must clean off the thermal grease from installed processors to see the speed.
- Replacement Note: Before installing a replacement processor, remove the protective cap covering the new processor’s connector.
- Replacement Note: When installing the processor on the logic board, align the processor notch with the tab on the processor holder, as illustrated. Then lower the processor straight down onto the socket.
- Note: Unlike in earlier Power Mac G5 computers, replacing a processor in Mac Pro (Early 2008) does not require running Apple Service Diagnostic for thermal calibration.
