I had the cash set aside, finally didnt have to sell old hardware to buy new.
Wheel bearing and hub assembly went on the car the otehr day...956.73 in repairs. No new toys for me anytime soon.

I got ram and boards, just waiting on a chip, which I should have fairly soon. No R4E though, everyone seems to be enjoying that board.
Your review I'm looking forward to. :rockout:

UD5 is on the way to me. Got P9X79 Deluxe, and ECS X79R-AX. Should get something from MSI and Biostar as well, at some point. Should be fun. ;)

I think I'll be the first one to post results :)

I received my 3930K on release date, but had to wait a week after that to get my Asus Rampage IV Extreme, you can read the details in this thread:

Project: Arctic Azure Mk V - i7 3930K + Asus Rampage IV Extreme + 3-Way GTX 580 SLI -

As far as OCing goes, my current rig is 100% stable at 4.5Ghz using 1.31V for Vcore, temps are very manageable maxing at around 60 degrees, I find this remarkable as this results are very similar to my previous SB build (2600K at 4.5Ghz @ 1.28V).

Now, going north of 4.8Ghz is another story, forcing me to up the voltage to 1.48V, and temps can reach 80~83 degrees, the processor becomes a completely different beast a 5Ghz, requiring 1.52V and hitting close to 90 degrees when running IBT, these results were found at around 70 degrees Fahrenheit ambient temp, I'm pretty sure trying at lower ambient temperatures is going to produce much better results.

The board has a plethora of OCing options, beyond what my MIVE board offered, and I'm still playing with them, trying to achieve the lowest voltage possible, if you guys have any advice, or can post your own personal experience, please do so :)

Seems to clocks similar to the 2600K's, slightly better, at least yours.

Nice setup Warlok!:rockout:

I'm also running the R4E and 3930k, unfortunately this mobo has been buggy but seems to be coming around. You might try raising your BCLK and dropping the multi down to obtain a lower vcore setting.
I’m running water cooling atm but will be going cold soon.:pimp:

Up to 4.5Ghz yes, but my 2600K can reach 5.2Ghz on 1.425V, I don't know, this processor will boot to Windows at 5Ghz at 1.46V, but it's not stable to run IBT unless I raise the voltage... :ohwell:

Nice temps and voltage! :toast: I'll try playing with the BCLK to get lower temps, thanks for the advice :)

I have my 3930K at 4.9Ghz @ 1.42v (1.436v when on load). 16GB of RAM @ 1824MHz 11-11-11-30 1t. My settings are below. I cannot for the life of me get my ram to run at 2133Mhz (1t or 2t). Anyone have any ideas?

Well, try as I might, I'm not able to run at 5Ghz at any voltage lower than 1.49V, temps are more manageable, but I don't like such high voltage. Right now I've settled for 1.29V at 4.5Ghz for everyday use, and the system is pretty stable, it's just that anything north of 4.8Ghz requires lots of current in my system, I'm not complaining though, running 24/7 at the same clock than my 2600K, at just a tad higher voltage, with the added benefit of 2 extra cores and 4 more threads ;)

MetalRacer, I tried using BCLK and CPU strap at 125Mhzand 40x multi, and it didn't make any difference, I upped my VTT to 1.2V and made the system a bit more stable, did you change any other settings in your rig?

Feizy, have you tried enabling the XMP profile for your RAM (if it has one)? All I did in my system was enable XMP from the BIOS and my RAM runs at 1866Mhz at 9-10-9-27 timings and 1.5V...

Another thing I noticed yesterday, when playing Skyrim, I couldn't enable Nvidia surround, I thought it was because of the OC key, I removed it, to no avail, turns out Surround is not compatible with any X79 board at the moment, Nvidia is supposed to release a new driver next week to fix this, ow come they didn't notice such a big issue during testing? :confused:

I have my RAM settings manually set to what the XMP profile would be. It runs fine at 1866 but not 2133MHZ. Maybe I need to up some voltage somewhere. We'll see...

My room temp is 34c its sucks so i've started testing some OC settings ill post them up soon, The Asus AI Suite II is giving me a warning when i play games the PCH temp gets up around 62c is this the main chip on the board located under the motherboards chipset fan?

Memory clocking, My CPU doesn't seem as good as the "K" chips in this thread :(:

http://img.techpowerup.org/111203/1200.jpg
You need to run Maxmemm multi or or Sissoft to get accurate memory bandwidth results in quad channel ;). AIDA64 seems to be single threaded and show little/no differnce between dual/quad as your results show.

@ 15th Warlock - Nvidia has released a beta driver to fix that issue.

What about some BCLK adjusting? Should be possible on SB-E
I am a bit jelly guys, I have this Rampage 4 on the desk and my CPU has yet to arrive -.-

Yeah, BCLK adjustment works great, allows maximum memory tweaking. I've been up to 140 MHz so far. Working on Bclk right this moment, actually.

Unfortunately, I see little in the way of performance gains...it just simply gives more options for how the ram and CPU speed "mesh" it seems.

So it is just more voltage and lucky chip if you want that 5ghz (as it has always been with binning)

To be honest, because I have an ES chip, I'm clueless. With 1155, I went through about 30 chips total that I bought for systems I sold people. Checked for maximum multi and 4.5 GHz voltage in every one. These chips cost so much that I doubt I'll have the same opportunity.


Because there are only two chips, and they have different amounts of cache, yeah, the same probably applies as to overclock ability as SKT1155, but time will tell. If things go well, I'll have another chip in the new year.
