I set VCore manually in BIOS but get the following measurements (motherboard is a Gigabyte EP45-UD3LR): BIOS = 1.356V CPU-Z = 1.328V HWMonitor = 1.33V (1.28V min, 1.33V max) Why is there a difference? Which value should I trust? The recommended VCore max for my Q9650 is 1.3625V which is the next notch on the list of VCore's in BIOS and I don't want to go over this value (yes I know that some people happily run their Q2Q at 1.4somethingV but I don't!). Of course if the real VCore is 1.33V when my BIOS says 1.35V then perhaps I can go a few notches above 1.3625V in the list. Thanks in advance for your replies.

My memory is rated at 1066MHz 5-5-5-15 2.1V and has an Extreme Memory Profile (XMP). In BIOS the options are "Auto", "Profile2", and "Disabled". I'm currently overclocking the CPU but planning to keep the memory at stock values. My overclocked system passes Intel Burn Test and OCCT at 3.99GHz but keeps failing Prime95 at even 3.90GHz. So I'm wondering if it's the memory settings? Q1) What exactly does "Auto" configure (I assume Profile2 is the XMP profile)? Q2) Does the XMP profile keep the dram voltage at 2.1V? Q3) Should I disable XMP and set all the memory values manually? Q4) Is it better to set the dram voltage manually when overclocking the system? Current memory BIOS settings are below (I set "Performance Enhance" to "Standard" when testing a higher overclock). Thanks in advance for your replies.
