Hi there,
so my second post, about cpu temp and voltage. Again sorry for my english...
Unfortunately it seems I've got a ''bad'' i7 6700k chip: VID is very high. With everything set on Auto in the BIOS the core voltage reported in BIOS screen is 1.328 V. Actually when I enter the OS and read the voltages with the last version of HWInfo (64 bit), cores VIDs are all around 1.4 V (maximum reached is 1.42) under load (OCCT stress test - linnpack). The same with the last ROG version of CPUZ. All of this at stock, no OC except the standard turbo boost @4.2 GHz. Ok, bad luck but I can live with it since it seems that voltages are anyway in the intel specification range, from what I can understand it is reported in the Intel datasheet (http://www.intel.com/content/www/us/en/processors/core/desktop-6th-gen-core-family-datasheet-vol-1.h... pag.114). It seems that this cpu can handle up to 1.52 V.
Problem are the temperatures: playing Witcher 3 on ultra (hairworks off) means that the cpu reach 80° C on some core...
I've tryed to manually adjust the Vcore in the BIOS: with a 1.28 V system is totally stable (even 30 min of OCCT stress test with full 100% load on all cores went ok). So it seems that the cpu can manage without problems lower voltages. And the temperatures drop to max 67° C under full load 😄
Now the main topic: I can't manage to set this maximum voltage using the adaptive mode, and this seems to be normal since adaptive is not meant to work for undervolting (at least that is what I understood reading some guides and threads). On the other side, offset mode does not work properly since it lowers even the idle voltage at a point that the system is competely unstable if I want the load to be 1.28 - 1.3.
Question is: apart from power consuming issues, can I stick with manual even if this means that that 1.28 V will be constant even in idle (already tested, even if the VID from the cpu drops to 0.8 V and the frequency drops too the Vcore sits on 1.28 V)? Or can it damage the cpu since in idle it is receiving more voltage than needed?
Thanks for your help!
P.S. already called for a possible cpu RMA. No: since the stock voltages are in the specified factory range and the cpu is working properly I cannot replace it 😞
