Tester Reveals Only 5 out of 10 Core i9-13900K & 2 out of 10 Core i9-14900K CPUs Stable In Auto Profile, Intel & Board Partners Yet To Determine Cause of Stability Issues

A tester at Chiphell has gone his way to find the stability rate of Intel's Core i9-14900K & 13900K CPUs as the chip manufacturer has yet to identify the root cause of the stability issues affecting these chips.

Intel Core i9-14900K & Core i9-13900K CPUs End Up Poorly In Stability Tests, Poor Silicon Being Pushed Too Hard

Over at Chiphell, a user by the name of kmdkai, has managed to put several hundreds of Intel Core i9-14900K and Core i9-13900K CPUs through a series of stability tests to determine just how well they respond to the "AUTO" profiles being dished out by board manufacturers.

Just recently, it was reported how Intel's latest 14th & 13th Gen CPUs end up doing poorly in terms of gaming and app stability. The main reason is yet to be determined but it looks like fixes being rolled out by board makers shed some light on the issue which happen to do with their BIOS releases which set these chips at their "Extreme" power profiles rather than using the baseline limits set by Intel itself.

The tester is the owner of a studio that buys several CPUs for their own needs. In invoices shared by the tester, it is revealed that he has bought and tested at least 100s of Intel Core i9-13900K and Core i9-14900K CPUs and it looks like almost all of the chips he acquired had some sort of issue in terms of stability. Motherboards used by the studio include ASUS's Z790, B760, Z690 and B660 boards.

The software he runs requires each CPU and PC to pass through a certain variety of tests and at the Auto profile set in the ASUS motherboards, the majority of CPUs fail this test and have to be resold. Based on these tests, the tester determined a probability rate respective to the CPU's stability & it is shared below:

• Intel Core i9-13900K "AUTO -253W" - 40/50% (4/5 out of 10 units stable)
• Intel Core i9-13900K "Reduced Loadline" - 50-60% (5/6 out of 10 units stable)
• Intel Core i9-13900K "B760/B660 Board" - 60-70% (6/7 out of 10 units stable)
• Intel Core i9-14900K "AUTO - 253W" - 20% (2 out of 10 units stable)
• Intel Core i9-14900K "Reduced Loadline" - ~30% (3 out of 10 units stable)
• Intel Core i9-14900K "B760/B660 Board" - 40% (4 out of 10 units stable)

So the out-of-the-box experience on an Intel 13th and 14th Gen CPUs is bad. It is reported that the chips might work fine for a week or a little over a month but usually end up producing stability issues.

Furthermore, the reason why a "Z" series motherboard produces more instability versus a "B" series motherboard is simply because the "Z" series is designed for tuning and overclocking & has higher limits set by default whereas the "B" series boards don't feature such CPU
