I have a 3960x and for me 1.42 is my limit for 24/7 but 1.4 is a bit safer ( 4.8 ghz). I have prime tested mine at 5.2 ghz at 1.57 for 12 hours and didnt degrade my chip at all whrn bringing it back down to 4.8.

This is with a proper full system watercool

You really wouldn't know if it is degraded until down the road. If it won't run at the same speeds with the same volts, you know it been degraded but not for a while usually.

I understand this. It was more a point to prove that 1.57v wont kill a 3960x or super quickly degrade it also.

I noticed something interesting regarding Ivy Bridge in Intel's MDDS database. (which lists spec codes and die code names for both engineering sample and retail processors)

For a little background info, there are three dies used for Sandy Bridge.

e13e5b65_SandyBridge.png

Two dies have been listed in the database for Ivy Bridge for a while: Ivy Bridge-HE-4 and Ivy Bridge-H-2. Based on the pattern for Sandy Bridge, it's fairly safe to assume that they both have 2 MB of L3 cache per core, and the top end GPU, which should be HD4000. Yesterday, another die was listed, Ivy Bridge-HM-4. This seems to be a cut down quad core die. It seems curious that Intel is bothering to create a separate quad core die when all of their quad core mobile SKUs have HD4000. Is Intel trying to get the die size down to the point that they can position quad cores in the entry level desktop market perhaps?

Based on the Sandy Bridge pattern, and the known information that there will be dual core Ivy Bridge SKUs with HD4000 and 4MB L3, I've constructed this table of the likely properties of the known Ivy Bridge dies:

bdf1cb51_IvyBridge.png
*Probable values that cannot yet be confirmed.
§ Based upon an image of an Intel QAY2 ES processor and an rPGA988 package size of 37.5 by 37.5 mm.
† Based upon the above values and this die shot, with an assumption of an unshown lower crossbar containing the memory controller.
‡ Based upon an image of an Intel QBNX ES processor.

EDIT: Images updated with die sizes, Ivy Bridge-HE-4 = 161 mm2, Ivy Bridge-HM-4 = ~126 mm2 and Ivy Bridge-H-2 = 118 mm2.
It appears that the area of this Ivy Bridge-HM-4 die could be less than that of the Sandy Bridge-M-2 die used for the i3-2120, and even for the low end Sandy Bridge Celerons.

Just want to say something about the ivy bridge cpu, it support up to DDR3-2800 in the bios. it can easily DDR3-2200.

his OC results are impressive.

The latest leaks seem to suggest that the current qualification samples (stepping 8 in CPU-Z) are of the E0 revision. There were D1 qualification samples of Sandy Bridge and there ended up being one more stepping, so it's possible that E0 won't be the launch revision for Ivy Bridge. I however expect that E0 will be the production stepping, as according to Intel's MDDS database the tray part number is CM8063701211700 for both the qualification sample (QC1X) and production (SR0PL) versions of the i7-3770K, and the last digit of the tray number typically changes between engineering sample steppings of the same cpu.

EDIT: The release notes for the 3103 bios for the Asus Maxiumus IV Gene-Z seems to suggest that there is an E1 Ivy Bridge stepping.

A poster at the coolaler forums posted this screenshot, which appears legitimate to me. Other recent pictures have confirmed an E0/L0 stepping.
507

By mimicking Ivy Bridge CPUID's in a VM and running the latest beta of AIDA64, HWINFO64, and CPU-Z I've determined the following about Ivy Bridge Steppings:

Stepping 0 is A0
Stepping 1 is A1
Stepping 2 is B0 (screenshots of these first leaked in mid 2011)
Stepping 4 is C0 (at least one screenshot appeared in the fall - the name of that CPU was still "Genuine Intel(R) CPU", so it was probably still an ES, not a QS)
Stepping 6 is D0
Stepping 8 is E0/L0 (L0 may refer to the stepping of one of the dual core Ivy Bridge dies).

Finally, Hiroshige Goto's report from Intel's presentation at ISSCC 2012 has confirmed that the die size of Ivy-Bridge-HE-4 is 160mm2, which is pretty close to the measurement of 161 mm2 I posted couple weeks ago. It will be interesting to see if my measurement of 118 mm2 for the GT2 dual core die will be as accurate. He also indicated that Intel stated that there will be a separate quad core die with 6MB L3 cache and GT1 graphics, confirming my supposition of a couple weeks ago. I'm hoping that Intel's academic paper on Ivy Bridge (A 22nm IA Multi-CPU and GPU System-on-Chip) from ISSCC 2012 will be released to the general public in the near future.

Thread Starter 
Thanks for the info guys, I will try my very best to make some updates tonight or at the very latest by Wednesday night.

Apologies for the lack of updates to thread, I've been quite busy maintaining other threads. Thank you for your patience.


Added to OP:


Intel "Ivy Bridge" Core i7-3770K is Capable of 100% Overclock: source

300

"The flagship product, Intel Core i7-3770K is a quad-core processor with 128 KB of L1 cache (4x32 KB), 1 MB of L2 cache (4x256 KB) and 8 MB of L3 cache. The processor operates at 3.5 GHz, which is the identical clock to the succeeding product, Core i7-2700K. When you take a look at differences between Sandy and Ivy Bridge, there wasn't a lot of changes on the x86 processing side, but that wasn't the focus of Intel engineers. As leaked results show, the processor is significantly better in graphics performance than Sandy Bridge. However, as key game developers say to us - the question isn't the hardware, it's the software."


Intel Ivy Bridge i5 3570K iGPU Benchmarked: source

"Intel have dramatically improved the integrated graphics processing unit (iGPU) part on the i5 3570K which is titled 'Intel HD Graphics 4000'. The improved iGPU packs 16 EUs which is up from the 12 EUs contained in the Intel HD Graphics 3000 featured on the i5 2500K and is expected to run around 1150MHz (no official confirmation yet). Other features of the iGPU are DX11.1, independent tri-display output, supports upto 4K resolution, OpenCL 1.1 and an improved Quick Sync engine."
