Motherboard makers apparently to blame for high-end Intel Core i9 CPU failures | Ars Technica (arstechnica.com)

Earlier this month, we wrote that some of Intel's recent high-end Core i9 and Core i7 processors had been crashing and exhibiting other weird issues in some games and that Intel was investigating the cause.

An Intel statement obtained by Igor's Lab suggests that Intel's investigation is wrapping up, and the company is pointing squarely in the direction of enthusiast motherboard makers that are turning up power limits and disabling safeguards to try to wring a little more performance out of the processors.

"While the root cause has not yet been identified, Intel has observed the majority of reports of this issue are from users with unlocked/overclock capable motherboards," the statement reads. "Intel has observed 600/700 Series chipset boards often set BIOS defaults to disable thermal and power delivery safeguards designed to limit processor exposure to sustained periods of high voltage and frequency."

This is the best summary I could come up with:

"While the root cause has not yet been identified, Intel has observed the majority of reports of this issue are from users with unlocked/overclock capable motherboards," the statement reads.

"Intel has observed 600/700 Series chipset boards often set BIOS defaults to disable thermal and power delivery safeguards designed to limit processor exposure to sustained periods of high voltage and frequency."

As we reported previously, the problems primarily affect high-end unlocked Core i9 CPUs like the i9-13900K and i9-14900K, as well as KF and KS variants of the same processors.

Intel releases these K-series chips to satisfy overclockers and tinkerers, but it's clear that there just isn't a lot of performance headroom left in these chips since Intel is already pushing their clock speeds and voltages to squeeze out generational performance improvements.

If it is, we should know more about the company's recommendations for safe power settings sometime next month, and we'll hopefully see new BIOS releases from the motherboard manufacturers that reinstate some of Intel's safeguards for these high-end chips.
