As the Apple iMac G5 series continues to gain market share among multimedia users many are finding out that the original system specifications are not up to par. Today we take apart an Apple iMac G5 and show you how to install additional memory modules to improve system performance.
The G5 iMac does indeed support dual-channel (128 bit) memory, it's just not mandantory. Most G5 iMacs just use a single stick (64 bit). I think barefeats or xlr8yourmac did some benchmarks and found that dual-channel is significantly faster during real-world usage.
