CPU: i7-2600K 4751MHz 1.44V (software) -> 1.47V at the back of the socket Motherboard: Asrock Z77 Extreme4 (BCLK: 103.3MHz) CPU Cooler: Noctua NH-D15 RAM: Adata XPG 2x8GB DDR3 (XMP: 2133MHz 10-11-11-30 CR2, custom. BIOS and other software display data rate, while CPU-Z doesnt. For example, if you had two supposedly identical systems that were getting wildly different results, that would be a reason to do some further investigation. because DDR spits out data twice per cycle. But I still find it useful for comparing different processors and different systems. Obviously, this is just a very quick synthetic CPU test. You also should run this test several times, with short gaps in between each test, so you can average the results. If your processor cores are busy doing other work, your CPU-Z benchmark scores will be artificially low. This is a measure of how “fast” your processor is.įor accurate results, you should only run these tests when your system is idle (from a CPU perspective). Second, it runs a CPU Single Thread test that measures the single-threaded CPU performance. This will peg your CPUs at 100% for about 7-8 seconds. First, the benchmark runs a CPU Multi Thread test that measures the overall CPU capacity of your system. ![]() The Bench tab lets you run a very quick (about 15 seconds) synthetic CPU benchmark against your system. If XMP were enabled, I would expect to see a DRAM frequency of about 1800.0 MHz (since it is double data rate RAM). This is bad, since I have DDR4-3600 memory in my system. In the example below, my DRAM frequency is only 1064.5 MHz. I have a lot more details about this in this blog post. You can still check your memory speeds though, since it is possible that the CPU can officially support higher speed memory.ĭepending on the processor, having XMP enabled can have a very noticeable positive impact on performance. It tells you about each memory module in your computer, including its. You probably won’t have this option on on most systems from large vendors like Dell or HPE. Launch CPU-Z and click its SPD tab if youre not sure what kind of memory is installed. This will let your memory run at a higher XMP speed rather than the default JEDEC speed. With most DIY motherboards from vendors like ASUS, ASRock, Gigabyte, and MSI, there is usually an option to enable Extreme Memory Profiles (XMP). ![]() This tab also shows the current DRAM frequency. With most mobile and desktop processors, you want to be in dual-channel mode rather than single-channel mode. It also shows how many channels your RAM is using. CPU Z 1.60.1 Download Now Released: Size: 4.The Memory tab identifies the type and overall amount of memory that you have in your system. ![]()
