No, Intel isn’t blaming motherboard makers for instability issues

Over the past few days, there’s been a firestorm online regarding a statement Intel made on the wave of instability issues facing high-end Intel CPUs. The original statement, which was shared with Igor’s Lab and others, appears like Intel wiping its hands clean of the problem and placing blame on motherboard vendors, and several media outlets have ran with that exact story. That’s not exactly what’s going on.

In statements shared with both Tom’s Hardware and AnandTech, Intel specifically says it doesn’t intended to “ascribe blame to Intel’s partners.” Currently, it seems that some BIOS adjustments can fix the instability problems on high-end Intel CPUs, but the investigation with Intel and its motherboard partners is still ongoing. Here’s the statement in full:

“The recently publicized communications between Intel and its motherboard partners regarding motherboard settings and Intel Core 13th & 14th Gen K-SKU processors is intended to provide guidance on Intel recommended default settings. We are continuing to investigate with our partners the recent user reports of instability in certain workloads on these processors.

“This BIOS default settings guidance is meant to improve stability for currently installed processors while Intel continues investigating root cause, not ascribe blame to Intel’s partners. Intel continues to work with its partners to develop appropriate mitigations going forward.”

The settings in question are as follows:

Current Excursion Protection (CEP) Enable
Enhanced Thermal Velocity Boost (eTVB) Enable
Thermal Velocity Boost (TVB) Enable
TVB Voltage Optimizations Enable
ICCMAX Unlimited Bit Disable
TjMAX Offset 0
C-states Enable
ICCMAX Varies, Never >400A
ICCMAX_App Varies
Power Limits Varies

For the options that varies, Intel points to its datasheets for 13th-gen and 14th-gen CPUs.

Although the instability problems have been ongoing for months, tensions are rising around the topic now. Over the past few weeks, we’ve seen updates from brands like Asus and Gigabyte offering a profile that fits Intel’s default specifications, even if it comes at upward of a 9% loss in performance. There are quick fixes available now, but we won’t have a full answer any time soon. Intel says it plans on making a public statement on the matter in May.

In the meantime, there’s been plenty of finger-pointing. Some blame Intel and others blame motherboard makers, and for a brief moment, it seemed Intel fell into the latter camp. The reality is that there’s probably some blame in both camps.

Speaking with motherboard vendors, they tell me that tweaking default settings is common to find a sweet spot between stability and peak performance. Every motherboard vendor has a slightly different definition of what that sweet spot entails, and they don’t always stick to Intel’s default values for high-end, unlocked CPUs.

On the other hand, it’s hard to imagine Intel doesn’t know that motherboard brands are doing this. After all, how are you going to separate a $250 motherboard from a $500 one and still stand out from your competitors? Although the instability seems to stem from the motherboard, Intel can’t wash its hands clean of the issue when it’s been ongoing for months without any official guidance.

My main question at the moment is what Intel really defines as “default” settings for its processors. When Intel publishes performance numbers, it backs them up with details about the configuration, and it maintains a page with these settings going back several generations. One detail that’s missing is how the BIOS was configured. Was Intel using its default specifications, or was it running tests with the out-of-the-box configuration on the motherboard?

That’s an important question as the saga of these instability problems continues when there’s a wide gap in performance between Intel’s defaults and what customers get with a new motherboard. I’ve reached out to Intel with this question, and I’ll update this story when I hear back.

It’s easy to boil down the recent fiasco surrounding as stability by saying Intel has “just turned off the overclock.” But with big gaps in performance on expensive, unlocked CPUs, it’s clear that Intel and its partners need to get on the same page about what exactly “default” means.

We might have an answer to Intel’s crashing crisis
Intel's 14900K CPU socketed in a motherboard.

Intel is facing some big problems with its 13th-gen and 14th-gen CPUs. As we reported on last week, gamers are returning high-end Intel CPUs in droves because of inexplicable crashes when playing the latest games. Now, we might have a solution, at least until Intel can tackle the problem properly.

The guidance comes from Falcon Northwest, which is a Portland-based system builder that received a rare perfect score from Digital Trends (read our Falcon Northwest Tiki review for more on that). Kelt Reeves, president of Falcon Northwest, said that the team has had "many long days of testing on many different CPUs that had developed issues here in our production and in the field from our clients." The result of that testing is a list of BIOS settings that should fix the problem.

I tested Intel’s XeSS against AMD FSR — and the results speak for themselves
Intel Arc demo: Ryan Shrout plays Shadow of the Tomb Raider on a gaming PC.

AMD's FidelityFX Super Resolution (FSR) and Intel's Xe Super Sampling (XeSS) are two of the most prominent upscaling options you'll find in PC games, and for one simple reason: They work with any of the best graphics cards. Choosing between them isn't simple, however. There are some big differences in image quality and performance, even with the same graphics card and the same game.

We've been testing AMD FSR and Intel XeSS for months across various games, but it's time to compare them point for point. If you're looking for a simple answer on which is best, you w0n't find it here. However, we'll still dig into the nuances between FSR and XeSS and what you need to know about the two upscaling features.

Gamers are reportedly returning Intel Core i9 CPUs in droves
Intel Core i9-13900K held between fingertips.

Intel's recent Core i9 CPUs are facing some dire issues, at least according to a new report from ZDNet Korea. In speaking with the outlet, an anonymous source in Korea responsible for customer service on Intel CPUs says that customers are returning more than 10 of Intel's 13th-gen and 14th-gen Core i9 CPUs daily, largely hailed as some of the best gaming processors you can buy.

The problem centers around Tekken 8, at least in Korea. According to the report, gamers using a CPU like the Core i9-13900K or Core i9-14900K will face an error message saying "not enough video memory" when launching the game, forcing it to close. This is even when the PC has plenty of video memory to run the game.
