vCore of AMD Phenom II X6 1090T on GIGABYTE GA-990FXA-UD5

MY system is with Gigabyte GA-990FXA-UD5 motherboard and an AMD phenom1090T. it is running well but the vcore seems to be bad on this board. It tells stock vcore is 1.30v within M.I.B menu which is correct except in pc heath menu it tells 1.344. However overclock is also not possible in this. It seems to me like a BIOS update. So do you think that updating the BIOS may ganna resolve this issue?

What are you reading from the 1.42 V? vCore tried manually to the desired value to provide? If VCore is set to Auto, it may be already times, which more power is given, as it should, because then automatically increases the voltage under load to ensure stability. But you should not something happen ... really. Just try out how the computer is running when you set the Vcore manually and hard wearing him quiet for a while to check the stability.

The voltage should now remain stable in most cases it is still too high. Limited depending on the board, unfortunately, the deflection of the downward fluctuation quite early. In my case, I have intentionally set the voltage a bit higher (1.4V) and am on the reference clock (with a NB voltage of 1.2V) gone with all cores on the level of the turbo core clock. Depending on the reference clock must, of course, the memory and HT frequency to be adjusted. Similarly, asynchronous PCI, ie uncoupled run. The X6 1090T if it were a reference clock of 225MHz (originally 200).

Whether he is down clocked at high multi in the BIOS again different from board to board. I have an MSI 890GXM-G65 where I think the BIOS version 1.7 to 3.7 GHz 955 (Multi-18.5) and was able to overclock QNQ still worked. With the new version 1.11 I was able to overclock to 4 Ghz, and what QNQ still works with version 1.7 did not work. Incidentally, I reach 4 GHz with 1.4V Vcore Prime stable.

I've read the MIT-1.475 V, both in menu and the PC Health menu Sun. Now I once again turned off and set TC 1.325v VCore manually. Previously 105Minuten prime95 is stable. It all fans with fan control to below 50%. Temperature by several degrees lower VCore down. Interestingly, while the Vcore fluctuates according to HWMonitor per prime95 between 1.230 V and 1.330 V. According to CPU-Z 1.232 V is permanently displayed. Let's see, maybe the same can also be another hour OCCT run in parallel. But then I cannot do anything about the way (just like now with prime95).

Run lynx to test stability. However, immediately reduce vcore, so it is too high compared alal frequency (and in any case for a daily not to exceed 1.45, preferably less!). I have your same 4 GHz processor and I keep them safely with 1.375. After which raises the frequency of the NB, even more important for performance. 4GHz should keep quiet and a 1.375 @ 2800mhz nb with 1.2 to see. I suggest you then use k10stat, and read the guide
