Long long ago, there is a way to apply the 771-pin Xeon processor to the 775 motherboard. The Xeon Xeon has the advantages of low price and high performance.
After a few operations, the DIYer with hands-on ability can use this extremely cost-effective CPU on the 775 motherboard. Today, once the history has happened again, who is this protagonist?
What happened in the past?
First, let's review the events of the year. After a large ship Xeon docked, the Great God found that the 775 CPU and 771 CPU pin definitions are similar, and the 771 Xeon processor can be applied by swapping two contacts and changing the mounting direction. On the 775 platform. Because the price of the 771 processor at that time was quite cheap and the performance was excellent, it became the darling of the DIYer.
The 771 CPU and 775 CPUs are installed in different orientations and require a 771 CPU. Rotate 90 degrees clockwise In order to install the motherboard. It is well known that There is a foolproof design on the motherboard to ensure that the CPU will not install incorrectly. Therefore, we can only use the cut-off design of the motherboard, or cut the corresponding interface on the CPU to use.
Early 'Hushubao' shielding method
In addition, some of the pin assignments of 771 and 775 need to be shielded. The initial solution uses the 'Hushubao' conversion patch to interchange the two contacts on the CPU. The design of 'Hushubao' is also constantly improving. More safe and stable, after a hard change technology appeared directly cold welding hard change.
Late hard reform
Going back to 2018 again
This year is a year of celebration for many DIYers. Intel has launched 8 generations of Core products, compared to the previous generation CPU. Added 2 cores , CPU performance of each grade has skyrocketed.
However for those like the smell master I started the DIYer of the 6th and 7th generation CPUs not long ago. This is undoubtedly a bad news, now only half the price can buy the performance of the Core i7 at that time. , 8th generation Core is not compatible with previous generation motherboards It is also quite uncomfortable for everyone who bought the previous generation.
We know that the motherboards of the 100, 200, and 300 series are also the 1151 pins. With the 8th generation Core, only the 300 series motherboards can be used. At the end of last year, there was a big god The Core i3-8100 can be seen as a Core i5-7500 without Turbo (actually the smell master thinks), and Successfully illuminate the Core i3-8100 after adding microcode to the 100 series motherboard bios.
After the success of the Core i3-8100, of course, the more advanced Core i5, i7 test, but unfortunately these tests failed, the motherboard or CPU showed varying degrees of burnout. Since then, 100, 200 series with 8 generations Core research seems to have stopped, but the recent research direction seems to have made new breakthroughs.
New discovery
After studying the definition of the contacts of the 8th generation Core, the technology has found the difference between them and the 7th generation Core, and found that it can pass Shielding CPU contacts The way to make the 8th generation Core is able to successfully light up on the 100, 200 series motherboard.
The shielding method is similar to that of the 771 CPU installed on the 775 motherboard. The insulating gasket 'Wang Shubao' is added between the pins and the contacts. After that, the 'Hushubao' product gradually appeared on Taobao. However, in addition to the physical modification, we It also needs to be optimized on the 100, 200 series motherboard bios in order to correctly recognize the 8th generation Core.
1. This magic modification technology is divided into three parts. When applied to most motherboards, we can take a single set of 'Hushubao' for shielding, that is, the group B 'Hushubao' in the figure is attached to the CPU. The corresponding location.
2. However GIGABYTE motherboard is not the same as most motherboards We need to shield a certain number of pins to ensure the normal operation of the CPU. In addition to shielding the B group 'Hushubao', we need to shield the A group 'Hushubao' in another place to illuminate the CPU.
3. Some other motherboards can't light the CPU even if they are shielded by 'Hushubao'. At this time, we will use the C group copper foil. Short the SKTOCC and VSS defined contacts , in order to successfully light up the CPU.
Taobao a business custom bios introduction
After the transformation of the CPU is completed, we have to start the BIOS of the motherboard. Unfortunately, we can only see the information we have. Buy Taobao's BIOS modification service And its price is not cheap, it seems that the price of the 100, 200 series motherboard lighting 8 generations of Core is not small.
More ideas
Many people will have doubts, since the 775 can be hard-modified, why there are no products of the 8th generation Core Duo on the market.
First of all, The 771 processor was not a brand new product. It is from the overseas elimination of server processors, and the 8th generation Core is Intel's newer technology, there is no need to make irreversible transformation of the CPU. It is estimated that there are not many Taobao sellers willing to make such high-risk products.
Do we need to save the budget and buy the previous generation motherboard with 8 generations of Core? The smell master personally thinks that in two cases, for the Core i3-8100, The technology used with previous generation motherboards and DDR3 memory is quite mature And does not require any magic modification, it can indeed be used at low cost and stable.
Biostar's H110MD PRO with the Core i3-8100 is currently the most stable combination, even Can be used on DDR3 dedicated memory , but I suggest that you still have to use at least the general rule.
For Core i5, i7, I need more steps to light up on the previous generation motherboard, I I suggest you use the 300 series motherboard directly. Now, the H310 and other motherboards have been greatly reduced in price, there is no need to save a little money to risk.
However, this kind of magic modification technology still has a lot of benefits. For those friends who started the 6th and 7th generation CPUs and motherboards like the scent master, if you are looking forward to the experience of 6 cores and the ability to be strong enough, you can try. Try this advanced DIY approach and get better performance through low cost.
Finally add a sentence, Magic reform is not something that everyone can do, and there are certain risks. Friends who want to start must carefully consider the consequences and make decisions..
