Intel CPU Issues and Crash Analysis
Jul 12, 2024
Lecture Notes: Intel CPU Issues and Crash Analysis
Overview
Speakers
: Main speaker joined by Wendell
Topic
: Stability issues with Intel 13900K, 14900K CPUs in gaming and server environments
Sponsor
: NZXT C1500 Platinum power supply
Key Topics
Intel CPU Issues
Red Herrings
: Initially thought to be VRAM limitations or BIOS configurations
Issue
: Crashes with Intel 13900K, 14900K CPUs and variants
Common Belief
: Issues with power profiles and microcode updates
Current Stance
: Intel may not fully resolve with software updates alone
Timeframe
: Ongoing issue for about 5 months
Analysis and Findings
Game Development Side
: Game crashes linked to specific Intel CPUs
Data Source
: Full crash database for two different games based on Unreal Engine
Common Errors
: GPU running out of VRAM, CPU-related errors
Time Running
: Servers crashing in a manner inconsistent with BIOS setup
Server Side Investigation
Server CPU Usage
: High failure rate for Intel 13900K, 14900K in servers
Failure Rates
: 50% of servers experienced some failure within 7 days
Data Sources
: 250 systems across three providers, mix of Super Micro and Asus w680 motherboards
Failure Types
: Various, inconsistent errors, sometimes CPU or memory related
Performance
: Failures observed even under lower power TDP settings
Consumer Impact
Consumer Market
: Less clear, but potential aging effect in consumer systems
Failure Rate
: Possible higher long-term instability in consumer usage
Server vs. Consumer
: More vocal reporting in servers; different handling in consumer markets
Solutions and Recommendations
DDR5 Memory Speeds
: Lowered DDR5 speeds helped stabilize some systems
Possible Recalls
: OEMs have replaced some CPUs from 13th to 14th gen
Competitive Comparison
: AMD Ryzen CPUs (e.g., 7950X) might offer more stability
Actions for Gamers
: Look for support from Intel and possibly replacements
Industry Response
OEMs (Dell, Lenovo, HP)
: Reporting significant CPU replacements
Intel's Acknowledgement
: Some indication Intel knows of the issue
Further Steps
: Intel needs to address gamers and step up replacements
Recommendations for Developers
Telemetry Analysis
: Game companies should revisit crash telemetry
Adjust Bans
: Some developers mistakenly banned players due to CPU-related client/server inconsistencies
Conclusion
Call to Intel
: Recognize the issue publicly and provide replacements where necessary
Consumer Advice
: Contact either presenter for more details if you experience issues
Further Research
: Both presenters plan deeper dives into issue based on new credible tips
