How does the new AMD Llano, A8-3870K in terms of overclocking? And how is that supposedly the strongest [b] board F1A75-v [/ b] Also on this page? Will outline in detail the possibilities and achievements. If you would perhaps be interested to read the detailed description of the Llano and the motherboard in my view, the link takes you to this article:http://extrahardware.cnews.cz/forum/...p?f=38&t=20332
[b] 3870K-A8 processor [/ b] is trying to entice a buyer multiplier only open for part of the processor, but also for the graphics core. Anyway, it's easier debugging and a lot of work to be made when the clock locked siblings. Even though everything is fine-tuning as the Llano CPU and graphics at the same time perhaps the most difficult part of processors present. We have restrictions attached output when no signal we may fall out, there are a few links STRAP values and memory clock running at graphics card via the BCLK, also increasing the NB-APU cycle. The speed can repeat that performance on the processor itself has an impact not only CPU frequency, but also its inner part (APUNB). The graphical part, of course, affects the frequency of the processor core and tact and timing of operating the processor can pamětí.Obecně nataktovat stable at 3500-3700 MHz and happiness according to GPU then it's around 800-900 MHz frequency stable. For the processor I've been holding voltages up to 1.55V (except validation) and 1.35V for APUNB, who is also the core voltage for the graphic. Aka Apu-PCIe voltage controller problems after I set "only" to 1.25V.
The validation of popular software, I used the AI Suite II, with whom I have excellent experience. Maximum boot into windows was possible while "only" at a frequency around 3750 MHz, high frequency idlení helped me the above-mentioned software. I shifted the voltage slightly above 1.55V and hope in the magic 4 GHz. And it really succeeded :-). The final stop on the frequency 4079 MHz.
Wprime to 1024 was the most demanding benchmark, not different from the maximum boot. 3744 MHz was the final time-value of 314s that fit well. This corresponds to roughly calculate the speed of processor core i7-930 or slightly overclocked Core i5-2500K.
On the contrary, shorter wprime 32M managed to pass under 10s, which is already a nice value for the quad-core processors.
Superpi to 1M decimal places with luck I somehow passed at 3900 MHz. I also tried other attempts, but they have not yet led to results. Time 19s, however, indicates that the processor trotlil maybe a little, not too effective. Superpí 32M I tried both the older Windows XP and the new Windows Seven.
The 32-bit Windows XP was the maximum for a longer calculation was 3770 MHz. So I have reached an outcome of the 3800 MHz clock, but the resulting time was worse.
