In order to further promote the application of collaborative robots in China's electronics manufacturing industry, the company has a full range of collaborative robot families, with its debut from March 15, 2016 to 17th at the exhibition Hall 1500, E1, Shanghai electronics production equipment.It is also worth mentioning that, as a leader in the collaborative

Some knowledge of DRAM, first recorded and then sorted out.1. What is memory rank?A memory rank is a set of DRAM chips connected to the same chip select, which be therefore accessed simultaneous Ly. In practice they also share all of the same command and control signals, and only the data pins for each DRAM is Separat E (But the data pins is shared across ranks). the term "rank" was created and defined by JEDEC, the memory industry standards Group. On ANBSP;DDR,NBSP;DDR2, Orddr3memory module, ea

running speed of the system. Optimize some settings related to the computer running speed to improve the system running speed. 1. How to overclock CPU in BIOS Generally, you can increase the external frequency or frequency of the CPU (that is, the overclock) to maximize the value of your CPU. Next let's take a look at how to overclock the CPU in the BIOS. Step 1 start the computer and press del to go To the BIOS settings page. Step 2 Select Frequency/voltage control from the main menu.

bandwidth provided by a dual 64-bit memory system is equivalent to the bandwidth provided by a 128-bit memory system, the results are different. The dual-channel system contains two independent, complementary intelligent memory controllers, and in theory, two memory controllers can operate at the same time with 0 delays between them. For example, two memory controllers, one for a and another for B. When controller B is ready for the next access memory, controller A is reading/writing primary me

Check the motherboard bus frequency, system frequency, DIMM jumpers are correct against the motherboard manual, check each jumper, order for "system frequency jumper--cpu frequency jumper--dimm frequencies jumper", set the CPU voltage jumper should be careful, should not be set too high. This step is useful for s

setup, which is actually two bank But the bank concept here is different from the bank mentioned in the previous analysis of the internal structure of the chip. To put it simply, the bank is the channel between the memory and the North Bridge chip on the motherboard for exchanging data, now, for example, SDRAM system, the interface between CPU and memory (that is, CPU to DIMM slot) is 64bit, Also means that the CPU will be sent to memory at one time

total workload crash. Memory mirroring replicates memory content synchronously by providing DIMM-protected memory. When a memory failure is detected, the system swaps to a mirrored copy until the faulty DIMM is replaced. New servers on the market support local memory mirroring: Mirrors only the partial memory of the server used by the task-critical workload. Obviously, this is a way to reduce costs. Proc

long as the buffer sizes of the two pools are the same. The FPA hardware supports the prefetch operation and the core sends the buffer address to the scratch memory (part of the data cache, that is, the L1 cache) of the core ), therefore, the request for free buffer only costs one cycle. Insert a bit. No matter whether the software implements the pool or FPA implementation, the buffer managed in a pool does not need to come from the same contiguous memory. However, whether in the octeon SDK or

cards need to work in this memory address. When this option is enabled, a memory address is reserved for the ISA card, and the system can only use 16 MB of memory. So, unless your ISA card needs to enable this option to work, you 'd better disable this option.10. AGP aperture size (MB) (AGP channel size)Options: 4, 8, 16, 32, 64,128,256This option allows you to specify the maximum amount of memory that can be used by the system Master Card, and manually specify the maximum size that can be used

speed mixing, the computer will be at the lowest speed access. • For most PCs, you have to fill in all the slots in a group, or you can empty a group of all (of course, the first group doesn't), and you can't just plug in a subset of the memory in a group of slots. · There is an upper limit on the amount of memory that can be accepted by the PC (the maximum value is available from the PC manual). If there is no manual, the only way is to find the maximum value from the practice. · SDRAM is a
