Apple Power Mac G4The Apple Power Macintosh G4/800 DP (Quicksilver) features dual 800 MHz PowerPC 7450 (G4) processors each with the AltiVec “Velocity Engine” vector processing unit, 256k “on chip” level 2 cache, and 2 MB of level 3 backside cache. It shipped configured with 256 MB of RAM, an 80 GB Ultra ATA/66 hard drive, a 2X DVD-R/CD-RW “SuperDrive”, and a 4X AGP NVIDIA GeForce 2 MX TwinView graphics card — capable of powering dual displays — with 64 MB of SDRAM. AirPort (802.11b) was available by custom configuration.

The Power Macintosh G4 (Quicksilver) series is quite similar to the “Digital Audio” series that it replaced, but the higher-end models — the Power Macintosh G4/867 (Quicksilver) and Power Macintosh G4/800 DP (Quicksilver) — have faster processors with larger level 3 caches. All models have faster, and/or more capable, optical drives.

Like earlier Power Macintosh G4 models, the Power Macintosh G4 (Quicksilver) uses the case design introduced with the Power Macintosh G3 (Blue & White) — complete with a fold down door on the side that makes upgrading very easy — but it is silver, which gives the series its name.

Apple Power Mac G5The Power Macintosh G5 “Quad Core” (2.5), along with the Power Macintosh G5 Dual Core (2.0) and Power Macintosh G5 Dual Core (2.3), are the first and last Power Macintosh G5 models to use dual core PowerPC 970MP (G5) processors, which have two independent processor “cores” on a single silicon chip.

The Power Macintosh G5 “Quad Core” (2.5) is powered by two “dual core” 2.5 GHz PowerPC 970MP (G5) processors with four optimized AltiVec “Velocity Engine” vector processing units (one per core), eight double-precision FPUs (two per core), 1 MB of on-chip level 2 cache on each core, and dual bidirectional 1.25 GHz frontside system buses (one for each processor). It shipped configured with 512 MB or 1 GB of 533 MHz PC2-4200 DDR2 SDRAM, a 250 GB (7200 RPM) Serial ATA hard drive, a reported “16X” dual-layer “SuperDrive”, and a NVIDIA GeForce 6600 video card with 256 MB of GDDR SDRAM.

Connectivity includes USB 2.0, FireWire “400” and “800”, a single-link DVI and a dual-link DVI port, optical digital audio in/out, two independent Gigabit Ethernet ports, and support for AirPort Extreme (802.11g) and Bluetooth 2.0+EDR.

All of the “multiple core” equipped Power Macintosh G5 models have three open PCI-Express (PCIe) expansion slots. The Power Macintosh G5 “Quad Core” (2.5) uses the same easy-to-upgrade “anodized aluminum alloy” case as all other Power Macintosh G5 models with the same removable side panel for easy access to internal components. Likewise, it is divided into four different thermal zones with nine computer-controlled fans for optimum cooling. However, this model adds a liquid cooling system that replaces the traditional heat sink.

Identifiers: Early 2005 – M9749LL/A – PowerMac7,3 – A1047 – 2061

Apple Power Mac G5The Power Macintosh G5/2.7 DP (PCI-X) features dual 2.7 GHz PowerPC 970fx (G5) processors each with an optimized AltiVec “Velocity Engine” vector processing unit and 512k level 2 on-chip cache. It shipped configured with 512 MB of 400 MHz PC3200 DDR SDRAM, a 250.0 GB (7200 RPM) Serial ATA hard drive, a 16X DVD+R DL/DVD�RW/CD-RW “SuperDrive”, and an ATI Radeon 9650 (AGP 8X Pro) video card with 256 MB of DDR SDRAM.

Connectivity includes USB 2.0, FireWire “400” and “800”, one single-link DVI and one dual-link DVI port (no ADC port), optical digital audio in/out, and support for AirPort Extreme (802.11g) and Bluetooth 1.1. This model includes support for PCI-X.

Like the earlier models, the Power Macintosh G5/2.7 DP (PCI-X) uses the same “anodized aluminum alloy” case, and likewise, features a removable side panel for easy access to internal components and is divided into four different thermal zones with nine computer-controlled fans for optimum cooling. However, this model adds a liquid cooling system that replaces the traditional heat sink. Custom configurations also were available.

NOTE

Users with any liquid cooled systems — but particularly users with Power Macintosh G5/2.5 DP (PCI-X) (June 2004) and Power Macintosh G5/2.7 DP (PCI-X) (Early 2005) systems — in active service would be wise to carefully watch for internal and externalleaks and if a leak or temperature anomaly is discovered immediately shut it off and notify Apple or an Apple Authorized Service Center.

As a precaution, those interested in purchasing a Power Macintosh G5 system on the resale market for long-term legacy use would be prudent to avoid the Power Macintosh G5/2.5 DP (PCI-X) (June 2004) and Power Macintosh G5/2.7 DP (PCI-X)(Early 2005) if the original liquid cooling system has not been replaced with the improved one.

Upgrade SSD in mac

The best SSDs for Power Mac G5s are ones with aggressive garbage collection, aimed to keep the drive running at top speed even without TRIM present. In the past, I’ve been recommended to go with Sandforce drives, but they are not the only option. Below are a list of recommended drives that have been confirmed to work on a G5. This list will be updated.

  • OWC Mercury 3G – works fine in both bays
  • Intel 320 – works fine in both bays
  • Samsung 840 EVO – only in the lower bay
  • Corsair F Series = Sata II models
  • OCZ Vertex 2

Do your best to research SATA I compatibility! – Power Mac G5s do use SATA I, but since it is older technology, some SSDs give unpredictable results. Try to figure out whether or not the drive is compatible with your G5. Read reviews, and search for other Power Mac users and their experience with the drive. If your new SSD is not “seen” by your Mac, try placing it in the upper or lower bays. Remove any other hard drives. Consider booting from another Mac to see if a later version of Leopard can see the drive.

Recommended Setup Note: Most SSDs come with some portion of the drive already partitioned to keep performance nominal. You can add to this partition by leaving a portion of your SSD unformatted. In Disk Utility, for instance, create 2 partitions. One partition is for your OS. The other partition, usually around 10-15% of its total size, is left as unformatted space.
