Slightly higher CPU, 48 MHz less on the ram and 36 more on the uncore. I might get a little better performance. Thing is I hate uneven CPU/ram/uncore speeds and I try and make numbers that seem 'nice' and 'balanced'. That's part of the reason why its at 4005MHz. This CPU has no problem doing 4.5GHz @ 1.336v (see submission in 4.5GHz LinX club) but I dont need that much power, I probably wouldnt even notice. When I work it hard, renders/decoding/encoding/simulations etc, it takes so long anyway its a walk away come back in a few hours scenario and if it finished 15mins sooner I wouldnt be waiting for it so I see no need to push it and create more wear and tear on all the components. I also dont like running EIST etc so its full speed 24/7 and I'd rather not push it like that. With the 6 cores and 12GB ram it does everything I want it to at the current settings.
You can't turn off EIST, as shown in your CPU-Tweaker shot. ASUS mislabels EIST in BIOS and it's really the turbo disable. With R3E, it's impossible to stop your cpu from dropping the multiplier to save power.

The point to going to 183bclk is you wouldn't be bottlenecking your memory. As it stands, sure your ram runs at 1866, but your UCLK is bottlenecking it to 1800mhz worth of performance. So as far as internal 'balance' of your cpu... 183bclk makes a lot more sense. If you jumped to the 23 multiplier and 183bclk(183.5 on my board) you get an even 4220MHz... What makes 4005 any more even/balanced than 4220?

Also, you're an overclocker! We don't do it because we'll notice!
