The ASUS X99-WS/IPMI' CPU socket includes extra pins that connect proprietary circuitry to extra contacts found on Haswell-E's land grid array (LGA). When combined with our customized UEFI, this exclusive feature offers comprehensively-improved overclocking margins, especially under extreme liquid-nitrogen (LN2) overclocking. You'll enjoy better margins for memory overclocking, better comparative memory performance under the same frequencies, and better margins for CPU overclocking with minimal voltage drop — so you're able to push the latest processors and DDR4 memory beyond their limits! OC Socket is 100% compatible with the new Haswell-E LGA 2011-3 processors. Forget limits, break every performance barrier with OC Socket!
