Overclocking with AMD Phenom X4 810

[Brruno]

I want to know about an overclocking with AMD Phenom X4 810. I have done overclocking before but on another processor. I am not having any ideas about the temperature and power consumption of this processor. So thought that you members will help me in explaining this topic. I am having knowledge that the values determined by you in practice can not derogate irrelevant, since those samples were carried out with special, the producers made available to you. There is therefore no guarantee that all test results presented (by you) in a similarly configured system can be achieved at our place. But still I am eager to know about it. Atleast i will get some ideas about overclocking a AMD Phenom X4 810. Any other notes regarding the overclocking would be grateful.

In a medium-class processor is still sought a way to extract a bit more free performance - it is overclocked. The Phenom X4 810 comes from the factory with a bus speed of 200MHz and a multiplier of 13, therefore. Since the multi is, however, has traditionally be overclocked via the bus. The first aim of such an action is the first brand of 250 MHz, which corresponds to a clock of 3.25 GHz. Problems we packed this hurdle, so was the next target set. It is important when overclocking to always throw a look at the separate adjustment of the memory, Northbridge and HT-Links-clock, since these components is raised otherwise 1:1 with the bus. Small parts are of advantage from a specific frequency. The 300 MHz were not to pack, unfortunately. Nevertheless, were extremely impressive 290 MHz Bus Speed out, resulting in the curved clock frequency of 3770 MHz.

The 300 MHz were not to pack, unfortunately. Nevertheless, were extremely impressive 290 MHz Bus Speed out, resulting in the curved clock frequency of 3770 MHz.

This increase means a clock to almost 1,200 MHz, but this was purchased at the price of the voltage. 1.55 volts were necessary for the processor alone, but also almost all other components on the motherboard had to be parallel to the CPU supplied with more energy, which is naturally solid at the power consumption. CPU-Z read on the site by the way, the voltage of the processor from wrong, because you can raise on the Asus motherboard with a small jumper the default voltage of 0.3 volts, unaware of what the program does not. And so it happens that a Phenom X4 in a complete system that usually requires only 200 watts, can send more than 330 watts into the race. 3.77 GHz can be considered quite as completely stable on our CPU.

Several tests, we have put together a small rating, the details are there as usual in the recommendation.

A 40 percent higher performance, the expense of an increase in power consumption by 80 percent: both no mean values, both positive and negative perspective. When overclocking you should find it not overdo a good balance. Half of the boost in clock speed should be sufficient, provided that the voltage by 0.1 volts to be increased. All processors are tested in the test without the power saving modes in order to demonstrate the superior performance. The fact that the feed of the latest generation power saving since not much more power. However, in order to demonstrate the savings potential of processors, power consumption in idle and under full load with all available power modes (C & Q, C1E, etc.) were tested.

At idle, as the Phenom X4 810 - and of course the 805 - on the same motherboard as the two previous models slightly worse dar. reason is that the voltage of the processor only 1.025 volts is lowered, while Phenom X4 940 and manage 920 in idle with 1,000 volts. Whether this is so desired by AMD, or maybe there is just a small mistake was not apparent in the short phase of testing. However, as found on several motherboards, the 1.025 volts idle should not be on the platform, but are directly on the processor. On the new DDR3 platform then shows what is possible in savings, including through the store. In idle the consumption of the entire system decreases by about eight watts under full load with Prime, which also calls for the store, there are even more than 20 watts. However, one should always consider this the platinum exchange that provides certainly for a few watts of difference. A true comparison between two different motherboards with different memory is simply not possible. When compared to the current Phenom II should also always be borne in mind that this works with 1.35 volts and the new generation with only 1.30.

A cross-platform comparison is still very difficult, too different, the underlying systems. Still, one can take the value at full capacity even with the Intel processors as extreme, with notice that our Intel test system nearly a Core 2 Quad Q9450 or the Q9550 no matter pulls out of the socket like a Phenom-II system. There is not only in performance nearly equal status, but also in the area of power consumption. The measurement of temperature takes place in parallel to measure the power consumption. The system will charge one hour, while the room temperature is unusually warm 21-22 degrees. The illustrated temperature is always the respective maximum value that was with the unit cooler Noctua NH-U12P determined with a matching 120mm Noctua NF-12P-premium fan. As expected, the significantly reduced power consumption beats down on the temperature. All under test processors benefit from the powerful CPU cooler, remain notable exception of Intel Core i7 hothead and the old flagship Core 2 Extreme QX6850 in the older 65-nm production. As already known from our previous processor tests, we try a new test subjects with a slightly reduced voltage to operate. With 1.30 volts from the factory, the new Phenom X4 810 is already working with 0.05 volts less than the two previous models. Those are, however, had modified the test in undervolting let down in, for a stable operation was possible only at 1.3 volts.

The hope is therefore on the two new models. Optimistic we reduced the voltage promptly by 0.2 to 1.1 volts. Until the Windows so that it was ever easy, but a second after the start of Prime came the blue screen. 1.15 volts, but we could easily do all the work, also ran by Prime stable. But major savings to the complete system are no longer noted. By reducing by 0.15 volts only a few watts could be saved and also the temperature has not changed, great. Surprisingly, however, the power consumption in idle is slightly higher (108 watts) than the normal voltage (104 watts), although it is according to CPU-Z both times correctly regulated voltage down to 1.025. Here there is perhaps a minor problem with the BIOS, which when manually set the voltage Cool'n'Quiet plays a trick for a second tool displays idle suddenly on 1.050 volts, which might explain the discrepancy.
