I usually advocate Prime blend as the best for a stability test and like to get nothing less than 8 hours out of it before I am content with stability.
Not unfamiliar with overclocking - clocked Q6600 3.6ghz @ 1.344v, Q9650 4.4ghz @ 1.392v and 920d0 4.2ghz @ 1.288v previously but am getting stumped with sandybridge stability at the moment!
Current clock I have is 4.6ghz using turbo, using DVID in bios so no LLC set and using offset to increase voltage. Settings below from memory:
Voltage: Normal (allow DVID)
Offset: +0.060v
VTT: 1.05v
System Agent: Auto
CPU PLL: Auto (set this as got CPU PLL Overvoltage on, so thought Auto would be needed for this to take effect? Probably wrong here and two different things)
DRAM: 1.5v
RAM: set to XMP Profile1 so correct timings, RAM perf set to Standard but was on Turbo previously with same outcome.
The above passes IBT with AVX instruction set at max memory (~6900mb RAM) for 50 passes - no problem. Temps get to mid 70's and voltage on load is between 1.336v and 1.344v - understand low volts for this clock but nothing particularly impressive overall.
Prime blend however will BSOD with 0x124 error code after a few hours. From what I have researched this is typically vcore on SB. I have yet to whack the voltages right up just as a test to see if this is the case but was wondering peoples thoughts on the following. Hits same voltage but temps just get below 70c on hottest core
Why no instability in IBT at this clock after 50 runs of max mem?
Ideas on tweaking VTT "just" in case its this? Same for system agent voltage?
Any help/input appreciated
