I often buy processors because I have a big studio with dozens of machines, and I occasionally install them and sell them. So starting from the 13th generation, 13900K started to be used, and 14900K was released to replace 14900K in batches. So far, at least more than 100 14900K have been passed through. Step by step from 13900K to 14900K, it’s hard to describe in one sentence. In one sentence, it can be summed up as follows: It is already enough and I need to pull more. In addition, I have bought a lot of both boxed and loose pieces. By the way, I can tell you my feelings about the boxed and loose pieces. Mainly the main motherboards are Z690 B660 and Z790 B760, used from 6 series to 7 series. Not to mention the BIOS. I have to go to the ASUS official website once a week to see if the BIOS update can solve the problem. Before I begin to summarize, let me first talk about my standards. [Fully defaulted and safe to use] The productivity software runs continuously for a week without freezing, crashing, restarting, or reporting errors. (Productivity software refers to various data calculation categories, including but not limited to matlab, R, finite element, VC, VS, large-scale office batch processing, etc.) Yes, it is this productivity stability requirement that PASS has lost many Us. First, set the Z board to full AUTO and default to no overclocking. The power consumption is 253W. If it fails, go to the B board. If it still fails, it will be determined to be unstable. Let’s summarize: 1. The probability that 13900K can be fully defaulted and used safely is about 40% to 50% (at most 4 to 5 out of 10 can be fully defaulted and used safely). Improving the anti-drop pressure can increase the probability by about 10% to 20%. Setting the voltage to worst on the Z board or going to the B board can increase the probability by 20%. The probability that 13900KS can be used safely by default is between 13900K and 14900K. 2. The probability that 14900K can be fully defaulted and used safely is about 20% (at most 2 out of 10 can be fully defaulted and used safely). Improving the anti-drop pressure can increase the probability by less than 10%. One special thing about 14900K is that it is basically unsafe to use on the Z board, even if the failsafe voltage mode is set. So I mainly use B boards. 3. The power consumption and temperature of loose chips under the same load are generally about 10~20% higher than that of boxed chips, so it is easier to trigger the power wall or temperature wall. 4. The stability of loose chips is slightly better than that of boxed ones (this conclusion is only responsible for brand new loose chips. Second-hand loose chips are most likely to have been picked up even if there are no indentations). The slightly higher voltage of loose chips may be a life-saving straw. But what's the use of easily decelerating at 100 degrees (the most outrageous 13900K chip I've ever seen has a 180W power consumption that reaches 100 degrees of thermal deceleration). 13900K loose chips are easier to stabilize, while 14900K loose chips are useless and completely slag. 5. Intel recently added baseline settings. I tested it immediately, and the result was: completely useless. It is just equivalent to helping you limit the failsafe voltage (Z board), default CEP, current wall, and power consumption wall. Doesn't help improve stability. After Z board adopts this setting, it is equivalent to becoming B board. 6. Before the baseline option was available, the stability of board B was better than that of board Z. However, the stability of Z board after adopting the baseline option is no different from that of B board. 7. I have only bought 3 pieces of 14900KS so far. It is too IQ taxing, so I will not comment on 14900KS for the time being. I will make a separate post later. 8. In particular, once I accidentally set the power consumption wall to 33 watts and found that the energy consumption ratio was satisfactory. It is strongly recommended that you simulate the low power consumption situation, there will be surprises. 9. Regarding the voltage, I have tried Intel failsafe on the Z board before. If you choose this voltage mode, the motherboard will indirectly become the B board. 10. Supplement: I have bought dozens of 13700K before, and all of them are as stable as old dogs, and there is no problem with any of them. Therefore, I personally think that if you want to close your eyes and use it with peace of mind, the 13700K is the most stable. 14700K is not as cost-effective as 13900K, so I have never been exposed to 14700K and cannot comment on 14700K. Conclusion analysis: The above is just my personal experience as a productivity user, which is equivalent to the conclusion that I spent money to try for everyone. Pressurizing is definitely the right answer, but how to increase it to a stable point, especially when long-term testing is required for productivity, is too energy-consuming. Sometimes the test may be fine for 2 days, but if there is a problem on the third day, it is very time-consuming. . So every time I encounter something that fails to test, I resell it directly. If you are just an average user, there is no need to care about my extreme productivity conclusion. It can be relaxed a lot. After all, ordinary users can still tolerate unstable situations that are not easy to relapse. For example, my own personal computer, the 14900K+Z version, by default only encounters a crash and restart [doge] once a month at most.
