Without touching the BCLK strap, I can run 2133Mhz without even touching the VTT or VCCSA voltage (even though the XMP profile calls for higher VTT voltage.) 2400Mhz wasn't too bad either given the timings. I started having trouble going past 2450Mhz but, it has been some time since I tried pushing them that hard. I've never needed to mess with those two voltage too often. I'm not sure what the exact numbers are in the BIOS.How much Vtt and Vccsa are you using? Mine is a bitch. It cannot boot to 2400MHz from cold boot, if I boot 2133 then pull up to 2400 it works.
Ugh... they are but, it's the only away I can get past 4.4Ghz on the 3820. It's probably the only reason why I might consider replacing the CPU, just to make OC'ing a little easier (and maybe 2 extra cores if the price was right.) The downside is that is seems that power saving features are simply disabled regardless of their settings when the BCLK strap is selected. So my machine eats an extra 20-30 watts at idle when I use it where while using just Boost, I can underclock stock vid levels and beef up the boost voltage but, I can only do that up to 4.4Ghz on my CPU.Never used bus straps tough... They seem odd to me.
That screenshot at 4.75Ghz wasn't completely stable either. At clocks that high, any number of settings could be the culprit and I don't plan on spending too much more time thinking about it, so I'm just going to settle with 4.625Ghz for now.
