In fact, I have been using this machine for a long time. Let's just sit back and write about your own tossing experience.
In fact, the original intention of starting to buy was nothing else.
Counting box dream!However, the student's dog is very poor, what to do, can only pick up garbage as much as possible ~ 771 performance is too bad, 2011 is a bit explosive budget, 1366 is right.
After some searching, I found this one
8-bay barebones system, with a 650W or 700W power supply, motherboard, RAID card, fan, two hard disk cages, as well as overweight, overweight and overweight chassis. Delivery to Beijing, the author Tianjin, freight is 30 yuan. 350 barebones + 20 hard drive cages + 30 freight = 400 yuan.
Small popular science, the barebones system is removed from the IDC or large company's rack, the RH2285 is a standard 2U rack server, is a large flat. At the time of delivery, oh no, after the logistics arrived (pay attention to the mode of transport), I watched Debongo leave the van with a van and stay in the spotlight. My weak chicken can't get this kind of thing upstairs once a year. Vaguely remember like 20KG? I was so helpless that I called two freshmen to help me (the honey juice beckons), and I tossed it into my cubicle.
Well, the barebones system is handy, and major items should be purchased one by one. The first is memory. ECC REG's vest is really cheap, as long as 23 yuan a 4G, this server has a full 12 memory slots. Buy him 32G~(4G*8) first
Then the CPU! Why do you consider the CPU afterwards, because it is very tangled. At the time, due to funding issues, I went on two E5620s. The recommended value was on the X5570. This was a higher frequency, but it was a 45nm process. More abundant budget can be on the six-core E5645.
I use this E5620, two pieces of freight 90. 2.4G frequency, 4C8T, 12M three slow.
On the hard disk, I chose two 146G 15500 SAS HDDs, including shipping costs 142 yuan. Dual disk raid0 array can have good speed.
Although it is a 2U chassis, but the layout determines that we can not go full-height graphics. Note that this server has a very disgusting point that most
N card is not brightThis is very embarrassing, GT710 outstanding light card can not be used. If you want to use this server to play games, there are two options. A is a knife card HD7750, B is an external graphics card. Then I choose the graphics card: HD6790
(Last appearance on board)
Well, it is a light machine. To achieve the above figure, three things need to be present. One is the PCIE extension cable.
The second is the carrier of the PCIE extension: the riser card. The riser card is something that comes with this server. It can convert a 16x to an 8x and a 4x. Obviously, the expanded graphics card does not have very strong performance. The bandwidth of PCIE itself is also sufficient. Using the riser card can ensure better scalability. However, you need to know that 4x slot 16x, the length is not enough, the right side will not be inserted, so we need to saw slot. Say it is a saw, in fact, it is recommended to use hot methods to modify. Because the server's materials are good, the PCI slot is a good quality bakelite. Saw with a small saw blade for an afternoon is enough. So I used a small blade and an alcohol lamp to heat the blade while it heated the other side of the PCI slot.
Look at the appearance of the motherboard before installing it, and then you will need to use the upper heatsink on the U strip.
Then, the third thing - magic change 250W power. This is for the sole purpose of supplying power to external SATA devices and external graphics cards.
We know that the ATX power supply will not be powered on by plugging it in separately. How to keep it open? Looking at the ATX definition, it can be seen that shorting Pin14 and GND can reduce Pin14's potential and keep it on. Then use DuPont line connection, hot melt adhesive can be fixed, very simple things. Then use an electric cooker box to pry a few holes to expose the SATA power supply, 6-pin power supply, and the power port and fan port to provide an insulation.
This motherboard does not have a sound card, and USB is very few, so we need USB HUB and USB sound card.
Now that all hardware problems have been solved, enter the RAID card, put two disks RAID0, format, install the system, complete!
Then look at performance.
Look at chess first.
Hey. . It's not as high as 2600K for my 4.5G, but it's already higher than my mistress's E3-1270V1, despite the fact that the frame is so poor. For X5570 will be better.
Then came the HD6790, a graphics card from Xiaochao to 900Mhz, which was comparable to that of the GTX650/HD7750. It took 150 at the time. Of course, using the HD7750 is even more cost-effective.
The dual 1366 chipset is definitely SATA2. Seagate's three-disc 2T garbage tray when the warehouse. Array card after a series of optimization, originally 130/130 disk running this result!
