Core i7 4820K Multiplier for Turbo Boost, What is considered to be safe everyday O.C.?
I finally got my 4820K in the mail today upgrade from an 3820, I wanted it because I was unsuccessful O.C. BCLK I was lucky.. I brought it from AMAZON and only ended up paying $339 AU $ Considering I sold my 3820 on ebay for 280, not a bad deal.
Sys Configuration: MSI X79A-GD45 8D 2133 Gskill RipJAWX PowerColour PCS+ 290 4GDDR5 EK Water Cooling Kit. 39" SEIKI PRO 3840x2160 TV as a monitor. Coolermaster 650 GX PSU LG Bluray Writer 250GB OCZ SSD 2TB seagate 7200.
So I tried to overclock today and it laughed at me
It seems to just want to Run at max stock speeds.. then Bclk went to 97mhz... lowering overall CPU to 3577MHZ anyways all sorted now
After updating bios and playing with settings, it took me hours to get turbo Boost working and clocking higher than stock, I finally got it running nice, I'm Happy at the moment I am sure it was the MAIN Multiplier and the C-State Settings..
at the moment all the advanced stuff is set of AUTO. (Voltages power management etc)
Ive set my memory to XMS. running at 2133MHZ I got MAIN multiplyer set to AUTO BCLK 100MHZ in Turbo Boost Settings, I got 1core 44x 2core 43x 3core 42x 4core 41x
Short duration 250W Long duration 250W Turbo BOOST 250W
Now I ask the turbo boost multipliers. would I be okay to push them higher for everyday use? ie, I do work on single threaded apps commonly 1-2 core programs.. so it's important to have high clock speed here. 3-4core threaded apps are not so important.. IE VIDEO EDITING, Some games use 4 cores.. so lower clocks are ok in my eyes
If I can have this processor running at 5 GHZ for single threaded apps, that's my dream.. but I don't want to harm my system. and I want it to stay reasonably efficient.. keeping the watts down when not in use is also my goal. As my system is Solar Powered.
A few questions if want to quickly answer otherwise I will google it all later tonight. (P States/C States) Whats the Difference? I want to know what settings control power.. IE.. idle to LOADED incase I get crashes during these events..
Thanks for reading my loooooong a$$ed message.. I am eager to see what the experts got to say.

I wouldnt bother adjusting the BCLK much. Just try raiding the multi and running IBT, see if its stable (watch temps), if its not stable, add some voltage.
