Upon my further googling, I've found close answers to my questions. Let me share and I hope this helps you with better understanding, too.Quote:

Quote:
Offset voltage is a value added to the base voltage of your CPU. If at stock you have 1.1V, and you set +0.2 to the offset voltage, you are stating that the maximum voltage is going to be 1.3
Load Line Calibration forces the voltage you set in the BIOS through the chip, and gets rid of Vdroop. Vdroop is a drop on voltage which follows Intel specifications to avoid damaging the CPU. WITHOUT LLC, when you set 1.35V on the BIOS, while you stress test the chip, voltage might drop to 1.3 - 1.25 V. When the test stops it will go back up. So Vdroop only is enabled while your CPU is under stress. This means you will have a larger voltage when idle than while doing work.
Therefore you need a method of having a lower voltage when you CPU is idling. Enter C1E. With this feature, the CPU lowers it's multiplier when it`s idling, but also lowers the voltage! This is why Offset voltage is useful. It dynamically adjusts the clock AND voltage to what the chip needs.
Without Offset you CPU doesn't know what maximum and minimum voltage you want. It will just stay at the same voltage the whole time, while idling and while doing work. If the voltage is not very high, the degradation shouldn't be substantial, but it's always nice having lower voltage when you don't need alot of power. Why would you want to use 1.45V when browsing the web when you could do the same at 1.1?
Also, this inderectly lowers the temps a bit. With lower voltages the chip is less hot, but when it idles it also underclocks and the temperature difference is very noticable.
From this thread.Quote:
Offset mode gives you more stability at lower maximum voltages. When settings the voltage change it from fixed to offset. You will often get lower stable voltages than with fixed, that alone is a great reason to do it. The other reason offset is sweet is that it doesn't keep your processor at a set voltage. This allows you to save power, heat, and add longer life to your processor. Just start at +0.005V and work your way up. I was able to get it working at -0.010V (which when under full load was 1.23V) but it wasn't stable enough.
For my setup +0.005V = 1.28V under full load.

And a good post on Vdroop.

Or it is a lottery. :(
It´s a lottery. Even Chips with the same batch are different. Costa Rica and Malaysia have good Chips and bad Chips.
I bought now a 3770K Batch 3214C557 (still in the mail) where the 3 = Costa Rica and the C give me hope for a good Chip, but there is no warranty.
Absolutely, binning is the only way.

Not so extreme like many of you, but this is what i got till now. Still testing with stock hsf. Atm my cpu runs at 4ghz with offset set to -0.080 (0.80v idle - 1.088v load), LLC standard, VTT 1.60v, Ram 1.60v @ 2133 9-11-9-28 1T. Room temp 26C, 29-36-29-32 idle and 90C max with linx/prime. Lowering VTT from default 1.80v to 1.60v didnt drop temp even 1C at load like some say.
A5G gives a red number if you set offset more than .065v. Is there any real problem with this because I am going to give a try with offset set to -0.090/-0.10v. I ll also try to oc ram at 2200.

That is a solid chip though phase makes a huge difference with Ivy, it brings it back to Sandy levels.

it's a costa rica C chip? i think i read people being excited about these ones right? lol glad i got a good one, least it seems good so far.
4ghz 1.065v (1.072 load)
I'm on the stock cooler at the moment, as i wait patiently for my new true 120 bracket. So for the moment I'm just shooting for the 4ghz and seeing how low i cant take the voltage. no long stability test yet, as i've been wary of temps.
realtemp has been reporting nearly 80*C for any voltage i set to 1.075 or higher, i think one core hit 82* at one point. but 1.065 seems to be keeping me closer to the 75*C range at the moment.

You are not using AVX on linx, so I'm sorry to say your results are nothing but irrelevant :(

You must have Windows 7 with SP1 and latest linpack to run linx with AVX.
I was not aware of the difference ;) (AVX and non AVX versions). Now I got LinX from elsewhere, which seems to be right one and you were right about 10-15ºC more :D

Sorry to be a bug but just trying to see whether it is due to the lid or just the paste.
You replace the TIM under the lid and put the lid back on. The socket retention mechanism holds down the lid so there is no reason to glue it. It is Intel's thermal paste that is the problem.Quote:

Picked up another Costa chip. 3209B542. Much better then the Malaysia one I had, and at least as good as the other Costas Ive had. Will report back when I have more.
Also picked up a Z77E-ITX. Incredible board, regardless of size. Just wish there were more ram timing options in BIOS.
EDIT: Best Ive had yet. 4.6 LinX AVX with 1.2V. Still testing.
EDIT2: Got about 10 minutes in at 4.7 with 1.2V before getting an error, but not a BSOD. So Im thinking 1.22V or so for 4.7.

With gaming, you could under clock it and it would get the same FPS as 5 anyway.
Once under water Ill push more for a few benches, then probably settle in at 4.8 1.25V daily. Debating on removing the IHS.
well dont doubt it do it as 10C less you will reach easy what you want i even game at less vcore much less, im at your same 1,485 using LLC 75% stable prime at 5Ghz due to the IHS removalQuote:

Batch: 3218C290
anyways, I figure this is as good as any a place to check.
all I'm doing is setting my turbo multi to 46, and adjusting my cpu voltage, I'm not OCing anything else, my memory is running at stock 1600mhz.
Is that the correct way to do it? and then I read I can lower the PLL to help out with temps?
I lapped the ihs and my true 120(stock fan in pull orientation) and i haven't gone over 78* on core 2, and core 0 seems to run a good 10-15*(max 65*) cooler than 2 while 1 and 3 run about 5* cooler than 2. is that normal? I'm guessing they really botched the internal TIM job, so I was thinking of putting on some AS5.
anyways, back down to 4.6, i may just settle at 4.4, not like I'm doing anything crazy, but I do like to see what my chip is capable of.
Now to redo my prime at 4.6ghz and make sure it's still good and stable, i'll post a SS tmw morning probably.
EDIT: here's about 5 hrs or so of prime
This 22nm technology should be running cooler but it's not, increasing fan speed has no effect, it seems that heat is not getting out of the cpu.
Idle no-load temps are jumping around by 10 degrees, 25-35+. Why are these temperature spikes happening?
