however today, while stress testing at stock using AIDA64 I saw the Vcore spike to 1.296, which is almost at the 1.3 limit, there was also a very brief temperature spike.
So I am thinking the AUTO setting is out of the window now so will try with a forced 1.216 setting as it was stable there and will report back
senna89 Tamb? if it's temp, while overclocked at 4.2GHz I never noticed a temperature greater than 81C and that was in a very warm room.
Thank you everyone for your continued help.
**** Update ****
Multiplier set to 42
VCore manually set to 1.216
Load Line Calibration set to Level 4 (levels range from 0 to 8 with 8 being 100 volts)
Spread Spectrum disabled
rest left on auto
CPU-Z / HWMonitor both showing 1.232 V in core voltage
HWMonitor showing that the Vcore does sometimes drop back to 1.216 V
as I know anything under that causes some instability at my 4200MHz clock.
going to keep testing especially with some gaming later.
***** MORE UPDATES *****
ok so after about 6 hours to testing/gamnig I got a 124 BSOD
so I went into the bios and thought just increase the VCore to 1.22 but back in windows it is still showing as 1.232 max 1.215 min
of course still testing, and everything is ok so far about 1.5hours in
Should I have increased the Load Line instead?
*** Edit 25/06/2013 ***
Ok so I got a 124 BSOD while gaming again last night, it runs fine for several hours, combination of uses.
This time I dropped the XMP setting for my ram, and Manually set to 1600MHz with all timings at AUTO
lets see if I can finally stabilise at 4.2 , then onwards and upwards
Load Line Calibration level 4
Spread Spectrum Disabled
Ram Manual 1600MHz/ Timings Auto
everything else auto
One thing to consider is that my install doesn't like the current Nvidia WHQL driver, I was more or less problem free (except for BF3 artifacts) prior to upgrading to Haswell, but I must give this some consideration.
