Wowzers, get ready for the world's faster Cinebench run, overclockers by the name of Tsalk and Splave put some LN2 on the 3990X and started overclocking. The result 5.3 GHz on all cores, and also 5.5 GHz on a single core.

The processor we reviewed last Friday appear to clock quite well when sub-zero cooled. The 5.55 GHz from Tsaik is for a single core, he used a single ddr4 module that ran on ddr4-1866 with CL13 timings. The motherboard used was an MSI TRX40 Creator. Splave on his end achieved 5.3 GHz on all cores with a TRX40 Taichi from ASRock,32 GB G.Skill's Trident Z Neo ddr4-3200 memory at CL11 timings. As you have seen in our review, power consumption at high clocks is pretty crazy, they used two power supplies of 1250 watts

All this resulted in a score of 39,518 in the multithreaded test of Cinebench R20. In our own test, the 3990X achieved 24,608 points.
