The 1800x model isn't responding to overclocking attempts.
The 1800x model isn't responding to overclocking attempts.
Approximately three months prior, I upgraded to an 1800x and immediately increased its speed to 3.95Ghz. Shortly after, my water cooler stopped working, and while trying to diagnose the overheating issue, I reset the CMOS, erasing any saved settings that might have affected the performance. When the new water cooler arrived, I left it running at its default configuration. Now, I attempted another overclock. Using Cinebench for a control test, I observed a significant drop—about 300 points—compared to my original benchmark when the PC was first assembled (1560 vs. 1200). I experimented with a minor adjustment to reach around 3.65Ghz, but the system crashed immediately after starting Cinebench. After resetting to default and retesting at stock speed, I noticed in CPU-Z that the core clock had plummeted to just 1.2Ghz, then briefly stabilized at 3.6Ghz once the test concluded. I’m uncertain if this is due to thermal throttling or if ASUS’s BIOS has become incompatible, but I’m still confused.
Exactly how you did it? Just try configuring TPU to TPUII—it should adjust all settings for you at 3.95GHz.
CountMike shared his experience on how he approached the setup. He mentioned adjusting TPU to TPUII for optimal performance at 3.95GHz. He described gradually increasing and decreasing frequencies until stability was achieved, noting that TPU caused an immediate crash. He also observed inconsistent behavior when changing frequencies manually versus resetting to defaults.
Begin by adjusting TPU to 1 or 2, then you can tweak the details. After that, it's how I OC my 1700x, TPU II. Multiplier manually set at 40.0. Voltage manually at 1.4v. LCL 5Power at 130%. It's stable as a rock, though YMMV due to "silicone lottery".
Begin by adjusting TPU to 1 or 2, then you can tweak the rest. After some experimentation that’s how I set up my 1700x, TPU II multiplier manually at 40.0. Set the voltage to 1.4v. LCL 5Power at 130%. It works fine as long as it’s stable. Of course, this is mostly due to the "silicone lottery." None of these adjustments helped. I’m really unsure if the issue lies with my motherboard or the CPU. When I first bought it it ran at 4Ghz without any problems, but after my cooler failed I left it at stock voltage when the new one arrived. Changing core voltage or multiplier causes crashes, even if I try 3.65Ghz @ 1.4v. It seems like an immediate power loss and sudden shutdown, no freezing involved.
Well, I managed to fix it, but it wasn't exactly what I expected. When corsair delivered my replacement H100i v2, they sent me one with stripped pegs, and the cooler loosened up, so it wasn't properly connected to the CPU, which caused it to shut down. Fortunately, I had some spare pegs from a friend who didn't need them, and now she's overclocking to 4.1Ghz stable at 1.4v. Thanks for the assistance!
