CPU INTEL Core i7 3930k UPDATE

One of the most powerful desktop CPUs of 2011/2012 even 2013 indeed, and, it would be ok if its just processor you want to pay. Somehow, whole X79 LGA2011 will magically suck the money out from your pocket if you attend to use all of its potentials. It supports quad channel, up to 64GB or DDR3 1066, 1333, 1600 with around 50GB/s of memory bandwith with power to push more than enough gaming graphic in SLI or CROSSFIRE cards without a problem.

I could say 3 personal facts for now about this CPU:
  • the processor sucks 130Watts so it heats up and REQUIRES water cooling
  • it is shame to have it if you dont need its power
  • if you need it it is shame to have it without 16,24 or 32 gigs of enthusiast RAM and use it well in demanding tasks as 3D, post production or video editing.
Its dirty expensive so think well if you need it so urgently. Yes, it has 6 cores + 6 hyper threadings, 12mb of L2 cashe... but, perhaps, you might consider much cheaper i7 3770k? When it comes to 39xx sandy bridge-3 series and comparation with with 3960x or 3970x EXTREME editions, 3930k gains better value for its price. EXTREME is a bit faster with few more megabytes of cash but far more expensive. It supports many new smart CPU features that could be found on official INTEL web site but the most interesting for average user is its mark "K" that means its unlocked CPU and VERY overclockable with good water cooling. Its default XMP jumps go up to 3,8Ghz but manually it can go much further, up to you and your machine... This CPU is very powerful but too powerful / expensive for gamer or even enthusiast. It does offer 2 additional cores and extra 4mb of cashe over Ivy 4770k or 3770k but gain, its price should be considered well!

Here is some custom benchmarks with DDR3 1600 CL9

comparing to 3770 Ivy bridge:

Experiance with INTEL MASTERS EXTREME 2133mhz DDR3 memory, UPDATED 02.2014.

INTEL EXTREME MASTERS - Limited edition modules
Official memory of the world gaming league
PATRIOT VIPER 3 DDR3 family, 2133mhz, CL11-11-11-27 

...designed with blue, high profile coolers. There are many kinds of enthusiast memories on the market, sometimes hard to decide which one to buy but, if we look better, most of them are very similar technically just with different cooling design. Speeds and latencies are things we all should think about and be thoughtful about its high profiles, ask ourselves how will it fit with our CPU and motherboard capabilities...!

Lets start with XMP profile that this VIPER 3 chipset memory supports. It is hardware overclocking information that should be initialized in mobo BIOS to gain true memory benefits. Otherwise, this modules will run at 1600mhz 9-9-9-24 instead of its stock speeds.

I dont know what is happening if you go with offered 16 or 32 kits but I can share my experience with 32GB on 2 pairs of 16GB kits. First of all, on ASUS P9X79 PRO manufacturer XMP profile (2133mhz, 11-11-11-27, 1.5V) will not be stable as manual overclock and there will be BSODs! The reason might be all 8 engaged DIMMs but thats the case here and I tried to resolve it. My experience tells me that good, and stable working clocks can be made with ASUS AI tuning software. It pulls maximum from presented hardware, calculating well together and CPU and memory "communications" + voltages but, dont forget to ask yourself do you HAVE water cooling because i7 3930k really requires one!

And... there is another very nice, manual settings, that give great results, response and performance. It was made with few manual BIOS setting as shown bellow:

- Manual DRAM Frequency of 2133
- DRAM Voltage (CHA, CHB) 1.5V
- DRAM Voltage (CHC, CHD) 1.5V
- DRAM Timing control 12-12-12-27-2T

BIOS images of setup:

And the performance:

Great memory for its price and looks nice too. Interesting that its mark LIMITED EDITION seems true because its hard to find it any more on the market or even EBAY but never mind, there is a plenty Patriot VIPER 3 memories, technically almost identical to these.

CPU Water cooler Corsair H80i

CPU i7 3930k requires better cooling. I dont attend to do any extreme overclocking, so, considering case capabilities and cooler performances... my choice was Corsair H80i. It gives solid cooling performances with optional PUSH and PULL airflow options, it will fit fine on the back of the Chaser A31 or HAF STACKER 935 WITH SLIGHT SCREWS MODIFICATIONS and X79 motherboards with "high profile" memory modules installed and, it is quieter than former model H80. I would have nothing against H100 but - IT WILL NOT FIT THIS CASE CHASER A31 OR HAF STACKER 935 with ATX motherboards and high profiles of DDR memory modules or upper motherboard coolers! It will fit only if you separate radiator and its fans with case grill as I explained somewhere on the blog...
CORSAIR H80i stock fans are a bit laud when the CPU needs air but those can be replaced with some other low noise fans if you prefer. The fans should be better quality like NOCTUA because, cheaper fans like COOLERMASTER "LED fan toys", will melt under raising temperatures during full or overclocked CPU loads! Anyway, CORSAIR stock fans will do good with manual low turns settings in BIOS and temperatures will be just fine. The fact is that LED on the pump looks great (and I assume that you already know that its color can be modified in CORSAIR software) but as I red, there is many people who's LED drop dead and left with just one color. Same thing happened to me so.... good luck.

Any new experience will follow... and here are some images from the evolving rig...

Fits well on the back side of the case:
