I venture to say that if you live in a cold place, even an air-cooler might be enough. A 360mm water cooler and good thermal paste will probably do the cooling, keeping temperatures in the mid-90s for extremely heavy tasks. Do I need a custom cooling system for the 13900K?Ī custom cooling system is only needed if you intend to push the system to the limit (or beyond).

The 13900K operating at stock frequencies, as long as the load lines are minimally adjusted, will present a consumption of less than 250W on full load (r23). If the power reading at full load (r23) is above this limit, it is very likely that an adjustment in the load lines is needed. For that use the HW-Info.Īlthough manufacturers provide motherboards and processors operating at higher voltages (to ensure system stability under adverse conditions).
If you are running cinebanch_r23, and you are getting readings above 250W, with the system in stock, something is probably wrong.Īlways compare the CPU power reading to the VRM power reading.
Does the I9-13900K consume more than 300W at full load?. It is necessary to think about the air/fuel ratio, the turbine pressure, the relief system, the cooling system, and do many, many tests to arrive at a satisfactory and safe adjustment. It is not enough to buy a turbine, a new ECU, make all the connections and start accelerating. Imagine that you decided to build a turbo engine for your car. On the other hand, when we decide to build our own system, it will be up to us to make all the adjustments. When a customer buys a computer from a specialized company, it is assumed that all adjustments have already been made at the factory. This is my opinion that I wrote in my guide. I know I may be completely wasting my time, but it's been a fun experiment none the less. I'm going to put it through the same process and see how much, if any difference there is in this method of recording the VIDs as well as put it through testing of 30 minutes of R23 at the lowest stable VCORE, re-run my RAM overclocking and timing, and see if I can stablize higher than the 57P/45E/50R that is my stable all core limit without throwing excessive VCORE to push through instability. I have another 13900K in the box I plan on testing either this weekend or early next week. Even 1.29 results in an error before the 30 minutes is up. This chip can only successfully complete 30 minutes of R23 at 55P/43/E/50R with 1.30 override with LLC5. I set the VCORE to adaptive and and got the same results. This resulted in exactly 1.410 VID gathered from my testing when running under load. Once I reloaded my saved bios settings for 57/P45/E/50R I first set the VCORE to override and set a value of 1.43v with an LLC 5. I didn't take any readings below 40 to save time, but also because I can't think of a scenario where I would ever run the P, E, or R, that low. Finally I disabled the E-cores again and ran the ring from 40-52. I then set the P-core to 8 and then ran the E-cores from 40-45, repeating the same process. I would boot into bios, record the VCORE reading and then move to the next higher multiplier and repeated till I got to 59. Then set the P-cores to all core and went from 40-59 multiplier. 
From the bios I started by disabling the E-cores, set the ring multiplier to 8, made sure the voltage was set to adaptive for VCORE, enabled Advanced L LLC and set AC and DC to 1, and set the LLC to mode 8. I remembered this afternoon reading about mapping the VID tables manually, so I did just that. Running an MSI Z690 board, I don't get the fancy SP scores to compare chips. I got bored after work and decided to start a bit of an experiment. I tweaked my back this morning and couldn't do much besides sit today.
