Got an old 2009 Mac Pro (model 4,1) that's feeling sluggish? This pair of Intel Xeon X5680 processors could give it a serious speed boost. They're 6-core (hex) CPUs running at 3.33GHz each. The big thing here: they've been 'delidded' - meaning the integrated heat spreader (IHS) has been carefully removed. This is often done for better cooling in tight spaces or for enthusiasts.

These are used processors, so they might have some cosmetic signs of previous use, but they're fully tested and working. MPN is SLBV5. They're just the processors - no cooling fans or heatsinks are included. Perfect for the DIY tech who's comfortable upgrading an older Mac Pro tower. A great way to breathe new life into a classic machine without spending a fortune on new gear. Make sure you know how to install delidded CPUs properly!
