1. Now there are special mining boards
expansion slots for mining boards: 1 PCI Express x16 slot, 5 PCI Express X1 slots
support the installation of 6 graphics cards
expansion slots for mining boards: 1 PCI Express x16 slot, 5 PCI Express X1 slots
support the installation of 6 graphics cards
2.
First of all, there is a special motherboard for mining machine, which can support multiple USB expansion cards. These graphics cards can be transferred by USB interface, and more than 100 graphics cards can be connected. In addition, as long as the home motherboard provides more than 4 pci-e1x slots, it can also use the adapter to connect more than 4 graphics cards. When mining, the requirement for data bandwidth is not high, so 16x bandwidth is not necessary
3. It is recommended that you take a look at the Z3 matrix mining machine of Diancun technology. It has high configuration, high performance and low energy consumption. When the main network of filecoin goes online, it must be the first choice for home mining machine.
4. Physical and chemical properties of diamond
(1) chemical composition: C. It often contains Cr, Mn, Ti, Mg, Al, CA, Si, N, B, etc
(2) color: light yellow, light yellow brown, light yellow green, brown, colorless (light yellow white, white, excellent white) occupy a certain number, rose, pink, light blue, green, black, Tan are very rare
(3) transparency: both colorless and light colored diamonds are transparent, and the measured transmittance of white and excellent white diamonds in colorless medium is more than 95%. The transparency of dark colored diamonds and ground glass etched diamonds decreases and appears translucent. The increase of inclusion content in diamonds also affects the transparency
(4) hardness: Mohr 10, new Mohr 15, microhardness 10000kg / mm2, microhardness is 1000 times higher than that of quartz and 150 times higher than that of corunm. The hardness of diamond is directional. The hardness of octahedron is higher than that of rhombic dodecahedron, and the hardness of rhombic dodecahedron is higher than that of hexahedron
(5) density: the density of diamond is closely related to the inclusion in diamond crystal. The density of pure diamond with colorless and transparent substance is 3.52g/cm3, and the density with inclusion is 3.44 ~ 3.53g/cm3
(6) polarizability: most diamonds show inhomogeneity under polarized light. Diamond belongs to equiaxed crystal system, which should be homogeneous in theory. However, diamond is formed in the geological body with pressure change, and the internal structure of diamond crystal is locally dislocated e to stress effect, so it shows inhomogeneous inhomogeneity, which is manifested in the inconsistency of extinction, For the first grade gray with very low interference color, few uniaxial crystal interference images can be measured
(7) refractive index (n): 2.4493 λ four hundred and thirty-six μ m)、2.4354( λ four hundred and eighty-six μ m)、2.4237( λ five hundred and forty-six μ m)、2.4176( λ five hundred and eighty-nine μ m)、2.4103( λ six hundred and fifty-six μ m)
(8) reflectance (R): 5.308% in oil and 17.29% in air
(9) lipophilic and hydrophobic: diamond is a kind of lipophilic and hydrophobic mineral. After rubbing oil on the crystal surface, halo can be seen. Oil droplets on the crystal surface diffuse immediately, while water droplets do not diffuse. Therefore, diamond can be separated by oil separation in mineral processing
(10) electromagnetism: diamond is a non-magnetic heavy mineral (P & gt; 2.9) therefore, electromagnetic separation (medium magnetic and weak magnetic) cannot be used in mineral processing
(11) conctivity: most diamonds are dielectrics, resistivity: 5 × one hundred and four Ω. Cm, type I and type II (IIA) diamonds are insulators, and the specific resistance is & gt; one thousand and sixteen Ω. The I-type (H B) diamond is a p-type semiconctor with a specific resistance of 10 ~ 103 cm Ω. When the temperature rises to 600 ℃ or drops to - 150 ℃, the resistance increases
(12) stiffness and strength: diamond has a great elastic molus, which is the highest grinding material in nature, with an elastic molus of 90000kg / mm. Because of its low friction coefficient and high antiwear ability, ball mill and cone mill are used to separate diamond. But diamond is very brittle and can't bear the impact of positive external force
(13) melting point: the melting point of diamond is 4000 ℃, the combustion temperature in air is 850 ~ 1000 ℃, and the combustion temperature in pure oxygen is 720 ~ 800 ℃
(14) luminescence: Diamond proces sky blue and light green fluorescence under X-ray, light yellow and sky blue fluorescence under long wave and short wave ultraviolet, but a considerable part of it does not emit light. Some in the sun after exposure to light blue phosphorescence. Blue and green fluorescence were observed under cathode ray
(15) gloss: it belongs to the standard diamond luster. Due to the melting effect and ground glass image, it can appear grease luster or gloss weakening
(16) dispersion: the dispersion of diamond is 0.044. Under the irradiation of natural light, it has a certain incidence angle to proce the decomposed spectral color on the diamond surface, commonly known as fire color
(17) thermal conctivity: diamond has good thermal conctivity, and the thermal conctivity is as high as 669.89 ~ 2009.66w / (m ᦇ 8226); The thermal conctivity of type Ⅱ (Ⅱ a) diamond is 2.5 times that of copper at liquid nitrogen temperature and 5 times that of copper at room temperature
(18) thermal expansion: the coefficient of thermal expansion is small
(19) cleavage: | 111 | medium, | 110 | incomplete
(20) fracture surface: shell like
(21) chemical stability: the chemical property is very stable, it does not decompose in acid and alkali, but dissolves in molten sodium nitrate, potassium nitrate and sodium carbonate
