, only the standard server-type ECC RDIMM, capacity 4GB, 8GB, 16GB, rated frequency is also 2133MHz, voltage 1.2, product number AD4R2133W4G15, AD4R2133Y8G15, Ad4r2133y16g15. However, Wei just said that the DDR4 version of ECC So-dimm, VLP RDIMM, LRDIMM and other types are also being developed, will soon be introduced. These memory are used by servers and workstations, and Wei Gang said they have been working closely with Intel, and its DDR4 memory fully supports the next-generation serve

operating system, one of which is Cpuinfo, which contains information about the CPU. We can directly open the view, or filter the keywords to view, because the content of the file is more, so we usually need to filter the keyword. The/proc/cpuinfo file displays information by logical CPU, not real CPU, and each logical CPU information occupies one paragraph, and the first logical CPU ID starts at 0. We first need to understand this, as to what is the logical CPU, which is mentioned below. To un

motherboard power supply 24PIN,CPU power 8pin. So now often see the motherboard power supply for the 20+4PIN,CPU power for 4+4pin ATX Power is actually an ATX power extension, the correct name should be "Atx/eps." Now the popular home motherboard CPU power often has a 8pin interface, the normal ATX power supply 4pin can fully meet its power consumption (left 4pin). The ATX power supply will have a 8pin interface. This is because Intel's Xeon series

recently a lot of friends asked the CPU to buy, the author today to briefly introduce how to buy processor products, as the entire host of the core hardware, CPU purchase is very important, the first thing to pay attention to is not to believe that a platform profiteers propaganda of what the multi-core to the strong processor, Currently the newer Xeon series processors are only e3-1230 V3, e3-1231 V3, e3-1230 V5 and e3-1220 V5.

interrupt controller. The seventh column is the specific equipment. In fact, our optimization method is also to the eth1 interrupt request evenly distributed on each CPU, from the beginning of Linux 2.4 to implement the IRQ binding on a certain CPU or some CPU, called multiple CPU interrupt affinity. To achieve this, there are several conditions: 1. eth1 corresponding interrupt controller must be IO-APIC chip, sometimes hardware support, but Io-apic is not enabled, need to adjust system startup
