When choosing hardware for assembling a computer, sometimes you have to save on something, since the budget is not rubber. In this case, the best option would be to save on the processor and purchase a more productive motherboard, because installing the new processor will subsequently be the easiest.
Currently relevant is the AM3 socket for AMD processors. For it, you can buy AMD Sempron 145, which has acceptable characteristics, which will be enough to complete the entry-level tasks. Let's take a look at its features sequentially, and also figure out how to improve its performance at times.
Motherboard compatibility
This processor can be installed on motherboards with AM2 + or AM3 sockets. In the first case, before purchasing, you should check compatibility with the BIOS version and the north bridge of the board. There is no contraindication for the second compatibility; all manufacturers declare support for the model. The main thing will be to determine whether the motherboard supports the ability to overclock the AMD Sempron TM-145 processor and unlock the hidden core. Why this is needed, we will consider a little later. It should only be noted that this is where the possibility of a significant increase in productivity lies.
Specifications
At first glance, there is nothing unusual in them that could greatly attract attention. However, the price tag, which is almost the lowest on all processors available today, is pleased. In fact, this "stone" is a classic single-core state employee.
The core core frequency is 2.8 GHz with an x14 multiplier. The processor is made in the form of a metal square with knives placed on it, intended for installation in the socket. This design is typical for AMD processors. The model is made using 45 nanometer technology and belongs to the Sargas family. There is support for 64-bit instructions, so there will be no problems with the operation of operating systems in the presence of a large amount of RAM.
For data processing there is a cache memory of the first and second level. The volume of the first level is 64 kilobytes, the second reaches 1 megabyte. As a result, it may seem that this is a typical budget employee, and there are doubts about the advisability of buying an AMD Sempron 145. The specifications are not the brightest, but they are quite enough for office work. However, you should not think that this is the maximum performance of this processor, because it has hidden reserves, which we will talk about now.
CPU overclocking
The first distinguishing feature of processors from AMD is a good overclocking ability. Users note that with proper dexterity, you can increase the frequency by almost one and a half times, and at the same time, the stability of the work is not violated, just as overheating does not even begin to appear even with the stock cooling system. In most cases, if you have installed DDR3 RAM with a frequency of 1600 MHz, the core can be overclocked to 4 GHz, which, undoubtedly, is an excellent indicator for a budget employee, but pleasant moments do not end there. AMD Sempron 145 Processor still has hidden secrets.
Unlocking the Hidden Kernel
Most computer forum patrons know that AMD single-, tri-, and five-core processors are often more advanced models that have one core locked for one reason or another. Sometimes a lock occurs due to a serious malfunction, and opening it will not lead to positive results. However, as practice shows, a fairly large number of unlocks makes it possible to get a fully-functioning dual-core processor, which is recognized by the programs as AMD Athlon X2 4450. Agree, it’s nice to get a productive “stone” for a penny.
Do not forget, however, that in this case it is better not to count on such an opportunity, since unlocking the AMD Sempron 145 core is akin to playing roulette - it all depends on why the second core was blocked specifically in your case. But if the discovery was successful, you can go to the third step of increasing productivity.
Overclocking an unlocked processor
Yes, after adding a second core, the processor can still be overclocked. First, make sure with the help of tests that it works stably at its base frequency. After that, changing the supply voltage and timings, you can try to gradually raise its clock frequency. Depending on the installed motherboard and power supply, quite serious results can be achieved. Some users managed to achieve stable operation of AMD Sempron 145 at a frequency of 3.7 GHz, but in most cases the limit becomes 3.3 GHz. But this is already quite enough to play the majority of modern toys from the heart, of course, if you have a decent video adapter.
User reviews about the processor
According to most people who bought this model, they do not regret a bit about their purchase. The reason is that, considering the price, the AMD Sempron 145 processor is worthy anyway, so even if there is no possibility of overclocking or unlocking the kernel, it will be enough for the first time. Subsequently, if you purchased a good motherboard with support for 4- and 6-core processors, you can always replace it with a more productive solution.
Among the main advantages, the following features are noted:
- High reliability.
- Low power consumption (and, as a result, almost no heating).
- Very low price, almost the cheapest solution in the modern market.
- Good opportunities to increase productivity.
- The ability to replace in the future with a more efficient processor if necessary.
- The best option for an office computer.
Of the drawbacks, most users call only one point - the need for a good motherboard that supports all overclocking capabilities to improve performance. If you plan to buy this processor for use "as is", then this moment can not be called a minus, since any motherboard with the required socket will do.
Output
As you can see from this article, AMD Sempron 145 is perfect for those who have a limited budget and a desire to build a computer with the possibility of further upgrade. It is recommended to purchase a more expensive and productive RAM, as well as a motherboard. The processor itself, in case of failure with unlocking, can subsequently be replaced by a more advanced model.
