ASRock X99 Extreme3 Is An Affordable Choice For Linux Users

For those in the market for an LGA-2011v3 motherboard this holiday shopping season, a very reasonable and affordable choice is the ASRock X99 Extreme3. For just over $200 USD you can get this DDR4-3000+ motherboard that supports Thunderbolt, ten Serial ATA 3.0 ports, 18-core Xeon processors, three PCI Express x16 slots, and numerous other connections for offering a feature-packaged motherboard at a modest price compared to other LGA-2011v3 motherboards.

With having more LGA-2011v3 processors than motherboards, in building the new 32 system Linux benchmarking test farm (, one of the motherboards I picked up for a new system was the ASRock X99 Extreme3 to go with one of my spare Core i7 5960X Haswell-E processors. While this wasn't a traditional motherboard review sample, I decided to write a mini review about it today as I've been happy with the motherboard for its low cost, feature set, and its daily usage now after several weeks in the test farm.

Over the past ten years at Phoronix I've reviewed dozens of ASRock motherboards and their manufacturing quality continues to improve while maintaining a great feature/price ratio. Leading me to the X99 Extreme3 for my latest LGA-2011v3 motherboard was it being among the cheapest motherboards right now that support the latest Core i7 Extreme and Xeon LGA-2011v3 processors. I picked up this motherboard for just $209 USD while it packs in the functionality of many of the higher-priced Intel X99 motherboards.
