Overclock I7 6700k BSOD
Overclock I7 6700k BSOD
Hello everyone,
I recently installed my new system using Skylake and performed some overclocking.
The setup includes an Intel i7 6700K at 4.5ghz with a 1.35 vcore.
Memory specifications are G.Skill 16GB with speeds of 2666MHz, operating at 15-15-15-35 MHz.
The system is running on an Asus Maximus VIII Ranger.
I also have a Corsair RM650i.
I activated the XMP profile and everything seemed stable.
However, yesterday I encountered a BSOD with the error code 0x1A related to memory management.
Could this be linked to the overclocking or is there an issue with my RAM?
When assembling the system, I used Passmark Memtest86 v6.2.0 and ran all drives for about 12-13 hours without any errors.
Now I test each drive individually for around 8 passes.
Is this sufficient, or should I extend the testing to 24 hours as some forums suggest?
Should I consider increasing the voltage by 0.02V per stick, or should I switch to a different Memtest?
Additionally, I run a one-hour stress test with Google’s StressApp memory checker.
Thank you all for your time and support—I really appreciate it.
I don't have sufficient background on overclocking to judge whether you exceeded the limits of your CPU's silicon based on the quality of its silicon. Still, a concern arose when considering your memory type—was it from Asus' QVL? I located the list but wasn't able to identify the exact memory model since it wasn't included.
I reviewed the document and checked the DDR 2666 section, looking for the g.skill details. Your specific memory model, along with the DIMM count, is needed to determine if it could be connected to your BSOD issue.
For my Asus Sabertooth X99 board, I bought 64 GB (eight 8 GB modules). The memory seemed normal until I turned on XMP mode; only 48 GB were recognized and the clock frequency dropped to 2133, despite the rating being 2666.
Switching to Corsair memory that is listed on the QVL resolved the problem without issues. It took several calls to Asus and g.skill support to resolve this.
I'm uncertain if this relates to your situation, but I thought it might be worth mentioning.
It might not be the memory issue. What method did you use to check the overclock stability? The memory controller is located on the CPU, meaning instability there could lead to memory problems too.
The most crucial aspect regarding overstocking is the CPU temperatures, which are often overlooked; you need to keep an eye on them. What were you doing when the BSOD occurred?
Thank you for your prompt response. It's clear this isn't within Asus' quality level. However, it doesn't matter since manufacturers can't verify each RAM package on the market. G.skill's RAM configurator confirms my model works with my motherboard. I think there might be an issue with the kit or my overclock attempt. The first stick passed Memtest86 after 8 passes, which took 9.30 hours. Now the second one is being tested. Do you think eight passes are enough to determine if my RAM is defective? Your quick reply is greatly appreciated.
A lot of answers have been helpful. I used x264 16T for 12 hours, ran OCCT on the CPU for 3 hours, and Rog realbench for 4 hours. I recorded a game through OBS, then played it with Potplayer. After finishing, I noticed something... Thank you all for your time.
The second memory module finished the memtest without any issues. I think my overclocking might be the problem.

Maybe lowering it to 4.4 and checking its performance would help.
I suspect a BIOS or driver issue—do you have the newest info from the motherboard site?
I increased 0.02v to my dram and the bsod switched from 0X1a to 0X19 bad pool header and 0x3b... I don't think that's the memory issue. In stock settings, my cpu uses 1.45volts vcore... This is extremely high for 4.2mhz... What's happening here?
