Sometimes the system hangs, with or without load. I do SETI in the night but only few times crash in the night. In the day it crash while I am working, with or without load. Is not a thermal issue, the THERMAL MARGIN in the day is about 40 degrees, in the night with SETI is about 25 degress. Thinking, the new hardware is the CPU, but I exchanged it two times and the problem continues. With the last one I received, I didn't used the Blizzard cooler and keep the AMD Super cooler (included and the included thermal compound but the same, today the system crashed 2 times, one in linux and one in windows. In windows I am using the lasted Crisom drivers and in linux also, the lastest one from AMD. If I get back to my A10 7950k (still in my hands) the system works perfectly. I did stress process to the CPU and the memory for hours, using heavy load, prime95 and other software (i don't remember, I am writing in linux this) and the system works perfectly for our, but working, sometime (doing different things) the system freeze totally.. Maybe is something in the BIOS.... I don't know Also, I did a full test with memtest86 and nothing Thank you |

My educated guess is it's the F3-2400C11D-16GM causing this. G.Skill only lists compatibility of these sticks for Intel Z77, Z87, and Z97 motherboards. Not a good sign. http://www.gskill.com/en/product/f3-2400c11d-16gxm" rel="nofollow - http://www.gskill.com/en/product/f3-2400c11d-16gxm I realize that's not what you want to hear so I'd at least test my theory by testing with a set that G.Skill Certifies to run with the board you have. http://www.gskill.com/en/configurator?manu=52&chip=696&model=1754" rel="nofollow - http://www.gskill.com/en/configurator?manu=52&chip=696&model=1754 |

Try disabling C6 in the UEFI. It seems to have resolved the freezing for a number of people using that board and certain "refresh" (Godavari) APUs. -------------

Thank you Xaltar. I did yesterday after reading a lot. Now, I have two question. 1.- Is so different the the 7850 to the 7890 for having this? I supposed (even, different internal code name) the only difference is the speed and GPU speed..... but anyway, since yesterday running without C6 2.- How much is the difference in watts (or something like this) of running with/without C6 state. Thank you |

The 7890, 7870 and 7860 are not just a higher clocked 7850 no matter what you may read on the web. If you look at more reputable review sites you will note that they mention refinements. While yes, in all likelihood they are harvested from the same wafer as the 7850 there is quite a lot that happens after the die is manufactured. All CPUs have, for lack of the right term, firmware. Changing values in this firmware can drastically alter the behavior of a CPU. This is one of the ways intel (for example) will differentiate an i5 and an i7, hyperthreading is disabled as well as part of the cache to create an i5 out of what would otherwise have been an i7 with perhaps a small portion of defective cache. In some cases the manufacturer will go a step further and actually physically laser cut the die to prevent the end user trying to re-enable a feature or unlock cores. The end result is that the 7860+ CPU range differ in more ways than just clock speed from the 7850 and earlier CPUs. One of the key refinements was improved TDP in order to handle the higher clocks and this I suspect is what is not playing nice with the C6 state as it was configured for 7850 and earlier. As to how much impact disabling C6 has on the power saving/power consumption I am afraid I can't say without testing it myself and I don't have a board for my 7870k at present. I would imagine not too much as C6 is just one part of the power saving features. -------------

My friends.. Thanks a lot. The problem is in the C6 State. After disabling it and testing for some days, the freeze are gone...... You are the best |
