need assistance quickly with unstable/slow 3950X
I've observed that my machine has been acting very sluggish lately. In the BIOS, the XMP profile for 3600 keeps disappearing and I have to reset it. Recently, it wouldn't restart even with a "15" postcode, so I had to re-seed my RAM but still couldn't get the XMP to stick. I experimented by mixing RAM sticks in different slots and reseeding the 3950X, eventually getting it to boot and maintain the 3600 setting. After that, I ran Cinebench and noticed my score was 1000 points lower than usual. I restarted and saw the XMP disappear again. Eventually, I managed to get it to stick once more, but running Cinebench still caused the crash. I'm unsure what's happening, so any advice would be greatly appreciated.
Let it be handled by PBO. PBO is superior to manual OC. There are four (?) levels, and the more advanced the level, the better the cooling requirements become.
For now, keep it at stock; stability of the memory is essential.
If you haven't begun yet, try testing with the SOC voltage method.
Also, verify your current BIOS version by visiting the product support page and reviewing newer releases for system performance improvements or memory compatibility updates.
If you're already using the latest performance BIOS, ignore this advice.
The post code 15 seems connected to memory issues. Consider slightly increasing the SOC voltage in the BIOS, starting with a rise of 0.01v at intervals, and monitor performance using Cinebench R20 for a minimum of an hour, aiming for longer if possible. Avoid exceeding 1.2v SOC voltage.
I rarely increase the clock speed. I use the machine mainly for work, so I keep it at stock to prevent problems like this. The only time I did an overclock was because my score dropped 1000 points compared to what it should have been without the memory issue.
I generally prefer not to mess with overclocks and just restore performance to its original level.
