Intel nonetheless would not know what’s inflicting its i9 desktop chips to crash

Why it issues: For months now, Raptor Lake players have been irritated a couple of stability difficulty with the chips inflicting video games to crash. For a second, it appeared as if Intel was about to push a repair. Unfortunately, the corporate tossed water on these stories, saying there was extra to the issue than was being portrayed.

Recently, customers have struggled with stability points associated to Intel’s Core i9-14900K & 13900K CPUs. Those with the processors have observed elevated sport crashing, main quite a few builders to difficulty help notices. Intel mentioned it might examine.

Reports that Intel had discovered a repair originated with the German weblog Igor’s Lab. It claimed it obtained an inner doc below NDA that mentioned the instability’s underlying trigger was “an incorrect worth in microcode algorithm related to the eTVB (enhanced Thermal Velocity Boost) function.”

For a short second, Raptor Lake customers believed Intel had a repair within the queue. Unfortunately, Intel mentioned stories figuring out the fault had been incorrect. It remains to be attempting to find out the trigger.

“Contrary to latest media stories, Intel has not confirmed root trigger and is continuous, with its companions, to research consumer stories relating to instability points on unlocked Intel Core thirteenth and 14th technology (Ok/KF/KS) desktop processors,” it mentioned in a press release. “The microcode patch referenced in press stories fixes an eTVB bug found by Intel whereas investigating the instability stories. While this difficulty is probably contributing to instability, it isn’t the foundation trigger.”

Igor’s Lab has since added an addendum to its report.

Intel developed eTVB know-how particularly for Intel’s Raptor Lake S processors to present them a burst of efficiency in video games and functions by overclocking the processor’s cores above the utmost turbo frequency below sure situations. Igor initially reported that Intel detected a displacement within the minimal working voltage on the Core i9 elements on account of publicity to elevated core voltages and {that a} firmware replace was forthcoming, which was solely partially appropriate.

In the meantime, players have developed workarounds, with some recommendation from builders. The crashes fluctuate relying on the title, with some producing “out of reminiscence” errors, others exiting to the desktop, and a few locking up the pc completely. Additionally, a number of the chips work high-quality for per week to a couple of month however ultimately begin having stability points. Unreal Engine appears to be a typical denominator among the many video games.

Gamemakers have totally different recommendation on the right way to keep away from the problem, however all are associated to clocking. Epic Games issued a help discover to encourage customers to regulate BIOS settings. Vermintide 2 and Warhammer 40,000: Darktide developer Fatshark suggested utilizing Intel Extreme Tuning Utility (XTU) to underclock the Performance Core pace from x55 to x53. Gearbox mentioned to take away any overclocks in BIOS or use XTU, although modifications made within the BIOS persist after a reset, not like these made with Intel’s software program. Outpost: Infinity devs urged downclocking from 5.5GHz to round 5GHz to keep away from crashes.
