![]() ![]() Once the score drops very low (~0, shown below), I have Intel XTU history of Max Core Frequency and that number doesn't tank (range 4.41 - 4.80 GHz). The CPU-Z score at that point is and remains for several minutes near the reference score, maybe down a smidge from where it was before. During the test, Intel XTU reports that the TSP climbs to a number higher than 125, but five minutes in when the Power Limit Throttling indicator becomes active the TSP goes to 125. As people have pointed out, the heat in the mid 70s seems okay. At the default power limits, a computer should never drop to 0 during the CPU-Z benchmark test.Ĭlick to expand.Yes, I am confused on why the CPU-Z score drops to ~0 ten minutes into the stress test (shown below). You need to figure out the going to 0 problem first. Do you have any mechanical hard drives in your computer? I am not sure if SSD hard drives can have these same issues. Sometimes computers can freeze like this because the hard drive is ready to fail. My verdict is that your computer definitely has a problem. I have run the CPU-Z benchmark about a million and one times and I have never seen the score drop to 0 while this test is running. Once again, the CPU is adjusting itself hundreds of times per second to stay within all of the limits. When it hits 125W, it slows down a hair to stay under this limit. If the power limit is set to 125W, the CPU will speed up until it reaches this limit. Power limit throttling works the same way. If the CPU can go faster without hitting 100☌, it will go faster. The CPU temps are sampled hundreds of times per second. That is not how Intel thermal throttling works. ![]() Some users think that thermal throttling is when the CPU drops to 800 MHz and sits there for a minute while the temperatures decrease. An Intel CPU can stay pegged at 99☌ for hours while it is thermal throttling. This means it will only slow down as much as necessary so it does not exceed 100☌. When a CPU reaches 100☌, it will start to thermal throttle. Thermal throttling does not change the power limits. When you run the HD Tune Benchmark, watch for sudden drops to 0.Ĭlick to expand.These two types of throttling are completely separate. I used to use HD Tune to scan for bad blocks on the hard drive. ![]() The BIOS you are using is from July 21, 2020. The problem you are having might have been fixed already. I would go to the Asus website to find the most updated BIOS version for your motherboard. The latest version might be newer than that. Your screenshot shows that your CPU is using microcode 0xC8. Anything unusual loading your CPU?Ĭheck to see if there are any BIOS updates available for your computer. When your computer is idle at the desktop, open the Task Manager and go to the Details tab. At the default power limits, a computer should never drop to 0 during the CPU-Z benchmark test. If you ever need someone to help you step on the gas pedal, I will show you how. That covers their butt but who buys a high performance car to drive around at 55 mph? Hopefully no one. Of course GM is going to recommend that you always drive the speed limit. A manufacturer or an end user can set the power limits to whatever they like. The datasheet shows that these are the "Recommended Value". If the potential for a <10% CPU performance really matters to you, and you are strongly CPU bound in your workload, then you can improve your cooling and try to tune it further. If this is for a mission-critical workload, I'd leave well enough alone and use it as is. If your workload is GPU bound for example, it isn't likely to change much. And that is only for the CPU, of course - it won't affect other parts of the system much. And remember, this is for a ~10% increase in clock speed, meaning you'll at best be getting a 10% increase in performance, though likely less than that - few workloads scale perfectly with increased clocks. Your case might not even be able to handle that thermal output. Which will consume more electricity, output more heat into the room, need more expensive cooling, be noisier, etc. 250W might be pessimistic, but you'll definitely be exceeding 200W at those speeds. OP: Whether or not this is an issue depends entirely on how much you stand to gain from a potential 5GHz, but as I said, that is likely to come at a ~2x increase in CPU power consumption. single threaded turbo speeds are irrelevant.
