AMD Trinity was released only recently and already know that i will be pivotal platform for the entire next year. We rented a board because Asus F2A85-V Pro, it was planted with A10-5800K processor and try what he can do. In today's article, so you will find only instructions for debugging Trinity at maximum capacity, but also very well made shorter review boards. O processors Trinity was written all across the web material and our own Naturally a review from Alex . The latter mentioned that preparing an article on the clock and tuning AMD Trinity, which is now receiving. The speed of the first recall itself processors and chipsets for socket FM2.
Although AMD Trinity were issued only in October this year (2012), the final pieces of abandoned lines already during the weeks of January of the same year! So now AMD was not delayed the development of processors, but while waiting for the orders to previous Llano APU. Now, there are six Trinity APU. Two lowest models are Dual Core, Quad rest are. This figure even after two CPUs with locked the plans that fall under the Athlons. Although not shown in the figure, there is also a Sempron for socket FM2.
Trinity the processor has more than 1.3 billion transistors, and including the GPU die size is around 246 mm ². Because the Trinity is based on the Bulldozer architecture, the basic structural unit of one module. It contains two cores, a shared L2 cache and of course there is the same as Bulldozer shared FP unit. The cores themselves there are any changes, and have assigned code designation "Piledriver", which belongs 32nm production technology.
If we look at the actual distribution of die, we notice that almost half occupies part of the integrated graphics core. It also features HD Media Accelerator for playing videos and convert them. Then there is the graphic communication memory controller. GPU comes under VLIW4 architecture that can be seen in modern AMD cards currently and recently. DX11 support is of course, support the three display devices Eyfinity mode as well. The most powerful graphics chip HD model 7660D has a core frequency of 800 MHz. The actual processor section contains the memory controller (or processor is linked to the controller), which can natively 1866 MHz memory, and memory also with very low voltage - 1.25 V. Each processor module has its own L2 cache size of 2 megabytes The die with the processor, there are also PCIe lines, display digital interface and most innovative unclock. This is called as a single integrated northbridge (UNB), only communicates with the CPU, but with GMC with graphics core. Even so, it can tweakovat as for example in Phenom. It therefore has its GPU (GNB) part and a processing part (CNB).
The most powerful processor model is A10-5800K, which in today's article, I use to show the clock. The basic clock is 3800 MHz, for maximum turbo jumps up to 4200 MHz. In practice, the default frequency varies continuously between 3800-4200 MHz. It all depends on the complexity of the application and the overall workload chip both processor and the graphics page. Chipset
For socket FM2 there are three chipsets. Two familiar from last year and Llano APU socket FM1. These are the A55 and A75. These chipsets are finally saw its use as well as on the new platform Virgo FM2. Recently we have had higher A85X. The processor communicates with the southern bridge bus through UMI. Most PCIe lines are part of the processor, FCH has another 4 PCIe x1 and can serve for example to 8 SATA / eSATA 6G ports, 4 x USB 3.0 and 10 USB 2.0, etc. FCH mediated through the converter and analog signal. The chipset is also integrated clock generator, it can be a limiting factor in bus clocking, since they will affect all other output devices and their possible malfunction. There is no communication with the IO. The last major thing A85X chipset, we must not forget is to support AMD CorssfireX (2 x 8 PCIe 2.0) and advanced RAID standard.
How to processor
Quality of processors is selected according to the basic voltage at which the CPU operates piece - VID. Somebody can estimate the series. In some series is more "quality" chips that can operate at its base at a low voltage. Not all the pieces are definitely the best, but have a high expectation that this really will be. The second line on the switchboard heat tells us general information about the processor. This is the A10-5800K in the retail packing. What commonly purchased in stores. More important are the last two lines. The second line is a batch processor. 1216PNT marks 16th Week of 20 12. Letters PNT then specify the day of the week and certain characteristics of the chip. In the last line we are interested in the last four digits, which indicate the serial number 0070 and determines the position of the wafer.
More importantly it VID - Voltage processor identification. In a state, in this case, the load status of all cores, the processor has a certain tension. It is within a few hundredths of a volt difference tenth as against another piece of the same model. Also UNB, not only has its own CPU VID. For CPU operation is fundamentally the CPU VID. For processors Trinity A10-5800K moves roughly in the range of 1.2875 V to 1.3875 V. If we have a processor that has a CPU VID of 1.3 V, it is with great probability the ideal candidate for the clock. And both the air, especially in an extreme way. And how does it determine CPU VID?
This can be achieved in several ways. A common method is to turn off the energy saving functions and features AMD Turbocor in BIOS and then the operating system will see the approximate CPU VID in the diagnostic program CPU-Z. This differs from the exact slight drops or falls down voltage. It depends how the motherboard behaves. This example also see identical software hwinfo . So far, probably the best method is a new software enthusiast Stilt. He recently gave the track external support mainly AMD and created a program tweakovací TCI K ². Functionality is guaranteed only to Asus, and then only in a few models Gigabyte and MSI and the remaining models. You can download it here .
