在插座 775 上采矿

Also on forums, miners often ask questions about whether the port bandwidth is important. Modern boards are equipped with PCI-E 5.0, which transmits 63 Gb/s through 16 lanes, while outdated ones transmit 4 Gb/s.

Bandwidth is not important for hash rate. This parameter should be taken into account if the PC is going to be used for gaming or other software that loads video cards.

Miners care about the quantity, because of which they use outdated processors, for example, on socket 775. Although there are more modern analogs suitable for mining, this equipment continues to be put together with powerful GPUs.

Pros and cons of mining on 775 socket

Previously, assemblies with Intel processors on socket 775 had one main advantage – low cost. The boards were not in demand among game enthusiasts and were used less and less often even in office computers. In 2014-2018, they were sold cheaper than modern analogs.

Processor power does not significantly affect the hash rate, so socket 775 was a great option for budget mining. Now the situation has changed. It’s hard to find unused hardware with LGA775, and their price is close to models with LGA1151.

GIGABYTE GA-G41M-COMBO-GQ sells for 4999 rubles and has only 2 ports for GPU, and modern ASRock H510M-HVS R2.0 can be found for 5190.

In addition, older models support RAM no higher than DDR3, and more often – DDR2. The maximum performance of the farm when working with cryptocurrencies that require a lot of processing power is limited. However, it is problematic to find in stores RAM release 2004-2008. To build a farm with a motherboard LGA775, it will take a lot of time, and the savings in this case is questionable.

How to mine on motherboards on socket 775

The answer to the question, whether you can mine on socket 775 – yes, cryptocurrency mining is available on a farm with any parameters. However, you need to understand whether the investment will pay off, given the growing hash rate of popular blockchains.

Necessary equipment

It is problematic to put modern graphics cards on a farm with such a motherboard. GPUs from the RTX series are rarely connected to equipment with socket 775, which leaves only long-standing GTXs that have not paid off.

Having obsolete equipment, the user can create a workingrig. It is worth noting that most of the suitable parts are difficult to find in stores. To assemble a basic farm, you will need:

• GIGABYTE GA-EP45T-UD3LR is an inexpensive board. You can find it on marketplaces for 1500-2000 rubles.
• Intel Xeon L5420 – a relatively powerful processor, which can be replaced by an even weaker one, as this part plays a minor role in mining.
• 2x2Gb DDR3 1333MHz – you can buy used copies for 400-800 rubles per piece.
• 2 NVIDIA GTX 1060 6GB – a video card suitable for mining. Inferior to the last RTX in performance by about 10 times.
• 2 ACCORD ACC-450W-12 – an old power supply unit, the power of which is enough to power the equipment.

The hash rate of this build is 52 Mh/s when working with Ethereum Classic. The cost of a kilowatt of energy in Moscow as of February 28, 2023 is $0.09. Under such conditions, the daily loss of the miner is – $0.0008. At the same time, the calculations do not include the commission of the service, that is, the real costs are a little more.

结论

The motherboard with socket 775 is obsolete, so new cards do not work with it in pair or are launched, but with difficulty. If you can’t use NVIDIA GeForce RTX 4090 or 4080, then GPU mining doesn’t make sense anymore due to the lack of profit.

It is recommended to switch to motherboards designed with cryptocurrency mining in mind, with more modern connectors. They are more expensive, but allow you to use more than 10 cards in a rig, and also support RTX. That said, it’s much easier to assemble a farm, as new parts are available at any store.
