MSI Afterburner is must-have software for anyone who wants to overclock their graphics card. Furthermore, you get some estimated frame rate performance figures for a selection of popular games provided by 3DMark, too.Īnd of course, these benchmarks are going to be useful for anyone looking into overclocking their rig – plus 3DMark gives you the ability to stress test the stability of your overclock (by running a looped benchmark over and over).ģDMark offers a free demo (which you can download on Steam) to check out its benchmarking capabilities for yourself. The package includes many gaming benchmarks that you’ll likely recognize the name of, including 3DMark Fire Strike (an older DX11 test), Time Spy (DX12) and Port Royal (ray tracing) among others.Īll of these benchmarks will give you a score and allow you to compare that result with other PCs using the same (or indeed different) hardware components, letting you know how well you’re doing comparatively to other 3DMark users – which there are plenty of – and perhaps giving you the opportunity to see if your system needs to be tweaked. The results of all completed tests may be graphed using our colourful custom graphing components.3DMark is one of the top benchmarking suites when it comes to putting your PC through its paces in terms of gaming performance. The PerformanceTest memory test works will different types of PC RAM, including SDRAM, EDO, RDRAM, DDR, DDR2, DDR3 & DDR4 at all bus speeds. The settings in PerformanceTest allow the user to force the RAM test to run on a particular CPU while accessing the RAM connected to another CPU. Use of NUMA, software applications need to be NUMA aware and coded in a way to prefer the use of local memory over remote memory. Each CPU can have its own low latency local memory, but can still access the remote memory of other CPUs. Non-uniform memory access (NUMA) is a computer memory design used on motherboards with multiple CPUs, where the memory access time depends on the memory location relative to the processor. Swapping to the disk may even be required for very large blocks. In the case where system resources are low, Typically it is possible to see a drop in speed when the block no longerįits in level 1 cache, then again when it no longer fits in level 2 cacheĪnd goes back to main memory. ![]() Way it is possible to observe the different access speeds for the different However onĮach subsequent step the size of the requested memory is increased, untilįinally a block close to the size of the system RAM is requested. Memory and runs through the block measuring the access speed. During each step of the test, PerformanceTest requests a block of Like the 'Memory Speed Per Access Step Size' test, is composed of many Very low ) and returns to the requesting program the address of the first Windows allocates the memory to the program ( unless system resources are When a computer program wants to use a section of memory to storeĭata, it makes a request to Windows for the amount of memory it requires. Vary from 1 (continuous sequential access), to 1/65536th of the size of the The size of the block of memory used for this test is one quarter theĪmount of system RAM or 512MB, whichever is smaller. And so on, until a certain maximum step size is reached. Next it runs through the same blockĪgain, except this time it accesses every fourth value and so makes four This occasion, it runs through the block twice in order to access the sameĪmount of data as the initial step. The same block again, except this time it accesses every second value. First, it runs through theīlock of memory sequentially, accessing every value. Large block, of memory in various sized steps. The first test type, 'Memory Speed Per Access Step Size' accesses a Users can choose between two types of test - Memory Speed Per Access Step Size and Memory Speed Per Block Size Memory is designed with this principle in mind and so, we should expect to see a decline in memory access time if we continually request addresses that are far apart from each other. It says that memory addresses which are near each other tend to be referenced close together in time. One principle of memory design is known as Spatial Locality. ![]() For instance, running an executable file from a disk causes Windows to copy the file from the disk to memory and then run the executable from there. Windows moves data onto and off of this strip as required. On 32 bit Windows platforms the size of each slot is 32 bits or 4 bytes ( 1 byte = 8 bits ). Each slot has a unique identifying value called its address. The strip is composed of millions (sometimes billions) of slots. You can think of computer memory as a long continuous strip. The Advanced Memory Test is part of the PerformanceTest application, and it is designed to test several factors which affect the speed of which data is accessed in PC memory.
