Your friend's i9 9900K can overclock to 5.0 ghz. no problem at 1.42 V and 80 degrees Celsius max temperature. Your i9 9900K can only overclock to 4.8 ghz. (4800 mhz.) on all cores at 1.43 V. and the max temperature is 85 degrees Celsius. Why is that?

The answer is "The Silicone Lottery." Intel and AMD have to bid to buy silicone wafers (imagine a thin slab of silicone 1 ft. x 1 ft. or bigger) from manufacturers in order to make their processors. Each wafer/set of wafers has a certain purity level (Purity levels are based on how much of the wafer is "PURE Silicone" and how much of it has impurities like small bits of bad metal alloys or other debris). Lets say Intel buys 10 silicone wafers at 85% purity level for their i9 9900K. Let's pretend that Intel can produce 10,000 i9 9900Ks from the 10 wafers. Then 6 months later Intel sells nearly all their i9 9900Ks. Now they need to buy more silicone wafers to make more processors. This time AMD bids higher than Intel at the auction, and AMD buys the 10 wafers at 85% purity. Now Intel is forced buy lower quality silicone wafers at 80% purity.

So even though you and your friend both have i9 9900Ks, their purity levels are probably different. Hence the reason why one i9 9900K may overclock better, require less voltage, and run at a much cooler temperature than another i9 9900K.

My name is Johnathan Smith, I'm the founder and owner of The PC Smith1. The name of my company is a play-on-words. My last name is "Smith" and I fix computers, so naturally I'm like a blacksmith for computers. Hence, the name "PC Smith." The number "1" however, has several different meanings. In binary computer code, the number "1" means "true." I wanted my company's name to stand for "true and honest" business. Lastly, the "1" also represents the QUALITY of services, upgrades, and computers that we offer our clients! In other words, we are "number 1" or "the best" at what we do!
