Do you suspect your i7-14700K is malfunctioning?
Do you suspect your i7-14700K is malfunctioning?
Hello All,
I'm not a tech expert, but I assembled my PC last year and faced issues such as "Out of video memory trying to allocate rendering resource." After some research, I found that Intel 13th and 14th generation models had known problems, which might apply to my system. At the time, I couldn't proceed with an RMA because I needed the machine for work. Following a BIOS update and using default settings, most functions worked again except for certain crashes, like Unreal Engine. Recently, while playing PUBG, my PC would restart on its own. A prime95 test showed errors similar to a hardware failure (error details attached).
FATAL ERROR: Final result was 922A259E, expected: 87610A79.
Hardware failure detected during a 288K FFT test – refer to stress.txt file.
Torture Test completed in 1 minute with 1 error and no warnings. Worker stopped.
After reading online, I suspect the issue could be due to faulty RAM. I ran memtest86 and found 5 errors (attached file). Should I request an RMA for my RAM sticks or is the CPU only defective? My RAM XMP was enabled during testing.
Here are my PC specifications:
- CPU: i7 14700K
- GPU: Zotac 3060 RTX
- Motherboard: MSI z790 tomahawk max wifi ddr5
- RAM: G Skill Trident Z5 7200Mhz
- Power Supply: Corsair 80+ Gold 850W RM
- Cooler: Noctua Nh - DH15 Chromax (temperatures reached 100°C during prime test)
Please help me out, as I'm really frustrated now.
13th of the month high-end CPUs come with a vulnerability, and harm caused by this weakness is permanent—updating the BIOS won't fix it once it's gone. Installing a new BIOS might prevent further issues, but it's not possible for your 14700k model. Send in a return request.
Your motherboard might still have the CPU running at an overclocked level; check the BIOS settings to examine the CPU information. These problems often stem from excessive overclocking. Additionally, XMP settings are also overclocking for RAM and the controller—consider lowering the XMP values or disabling it to test if your RAM performs better.
If it has been running at 100C for some time, you might want to consider sending it in for repair. However, you could try adjusting it a bit first before doing so. Make sure to update the BIOS on your MOBO before proceeding. Then review the thread—post 50 and all related links. I had to make these changes on my 14600K. My model never actually hit 100C like yours because I was aware of the problem and its risks, but the adjustments from the videos and the Reddit link pushed it to higher temperatures.
Hello, thank you for your message. After reviewing the details, it seems your CPU is using the Intel default settings, and there was an option like Game Boost in the BIOS that you haven't activated. Disabling XMP and running the test passed, but when you re-enabled XMP and encountered 7 errors during testing, you should consider what those errors might indicate about your system.
Hello all,
I’ve done some additional memtest checks. Once I ran the test without xmp enabled, it passed, then again with xmp enabled, but then it failed with around 7 errors. This raises a question—what does this mean? My RAM is fine, but the CPU seems to be the issue.
Hello, thank you for your message. Yes, I have time to handle the RMA. My air cooler works well, and I read that during stress tests it can reach 100°C if you don’t do heavy video rendering. Noctua nh-d15 was good in that situation, but should I rethink and purchase an average AIO? Could you explain what undervolting means and how it might impact my CPU performance? I’m new to this topic.
The ram isn't stable with the current xmp configurations. Reduce the frequency. 7200mhz is too high; lower it to 6000mhz and recheck. You might need to adjust several settings.
