Is there some kind of bug with Intel Burn Test? I get higher load when using 6 threads opposed to 12?
nvm found this:
Still a bit strange though I seem to get slightly higher temps with 6 threads instead of all.
I think I'll stick to Prime95.

I've settled at 4.6ghz with 1.3V (slightly less actual), 70C load under Prime95 with all the other voltages just left at stock. Really good air cooled imo although I think my FT-02 is a big help as I've always had shoddy case cooling in the past.
I'm delighted with the chip and the X79 platform as a whole which is just as well given the cost.
P.S. running memory at 1600mhz now can't seem to get 1866 fully stable... but I guess it's not that big a deal with it being quad channel.

Wow what a difference a motherboard makes, I bought an X79-UD3 because I need to RMA the Asus P9X79 because of faulty audio (jack sensing isn't working)... I cannot get 4.6ghz on the Gigabyte to save my life even with massively increased voltages, I'm just getting a xxxxx124 BSOD whenever I try to run anything remotely taxing.
Worst still I have to use PCI-E slot 3 because the main slot is ridiculously close to the CPU socket and blocked by the heatsink.
This Gigabyte is definitely going back.

I received P9X79 PRO today and it's again rock solid at 4.6ghz with only v-core increased to 1.3V and rest at stock.
I found the Gigabyte X79-UD3 to be a terrible board for overclocking, any attempt to run at 4.6ghz resulted in a fairly quick BSOD.

This MSI board sounds like very similar performance to the Asus board described above being 4.6Ghz solid only adjusting CPU VCore to 1.300 for a 3930K.
Now getting into windows at 4.8Ghz but freezing up shortly after launching prime but haven't had stared playing with the other settings at that frequency yet. Still got faith in this chip to be good for it when I'm finished. One thing that I have learned about overclocking this platform is that with X79 memory above 1600Mhz is that it needs to be really good quality DIMM sticks you pick if you want to get the best out of your system as chances are this will be the first ceiling you hit and before the CPU limit.

No idea dan just seen it in live update there I'll be taking my time to have a good read about what's new & changed and waiting for a bit of user feedback to make sure nothing too weird is going on with it before installing it as I've still got plenty to play with in this one to see how far I can push it, the only slight concern I have with this version is possible memory managment issues have you noticed any various memory related blue screens whilst overclocking the CPU? It'll be interesting to see what's in the fix.
Did you read the ReadMe or just go for it lol?
*edit
Are we even talking about the same boards (MSI) ? cause the new version I'm seeing is 1.60 but thx for the heads up anyaway

Hi Ghost sorry I'm talking about the R4E, I was having trouble with my new GPU, so I just went for it, ASUS website just said system stability fixes etc!
In my experience of overclocking, I only pushed so far as it would fail IBT not really had any blue screens etc, did it pretty quickly, banged it straight to 4.7 upped voltage to get it to boot into windows and IBT stable then set LLC high and backed volts down again (1.375) memory is at 1866mhz. Did try to reduce my timings once that but it didn't boot, (9,10,9,28,2 to 9,9,9,28,2) but I gave up instantly, voltage is fixed at 1.5v (for ram) maybe that's y? But like I say, only tried the once! Lol

Yeah you need to balance the tighter memory timings with increased DRAM voltage I found 1.65Volts was needed to do any RAM overclocking but have since discovered its the Corasair 1866mhz rated memory that's been holding my overclock at 4.4 or 4.5ghz. I'm surprised it's locked on a mega board like that prolly just had to set the voltages to manual before adjusting.
I was told by a technician at another online retailer a couple of months back that Corsair 1866mhz RAM a caused instability issues with CPU overclocks on all the ASUS boards apart from the mega R4E you have as there'd been a fix for it.
I've been starting to think that there's a similiar incompatibility issue with MSI hopefully fixes the issue as I'm having to underclock my memory at 1600mhz to allow higher CPU clocks beyond 4.5Ghz.
I'm not a big fan of having to buy slightly more expensive higher rated memory and run it below it's expected tolerance rate.

No its not locked, i fixed it at 1.5v when i set it up, it defaults to 1.65 
must admit, im not so clued up on RAM overclocking (wouldnt call myself amazing at CPU either lol, but that was easy) which is why i only tried it the once, also had to reset the CMOS, which meant loading all my settings so gave up lol

That sounds similar to mine Jeffy, I'm still impressed by how cool it runs at 4.6ghz (low 70s in Prime95), I was expecting it to be a furnace. Air cooling has come a long way since I last had it though and the low voltages helps.
Not sure why you're having memory trouble Ghost, I've got the Samsung Green stuff running CAS10 2133mhz easily @1.4V highly recommend it, it's good value at £100 for 16GB and plus it's low profile so doesn't block the heatsink.

Are the i7 3930K's that Overclockers is stocking, C2 stepping?
Yeah I wish I'd went for the Samsung Green stuff now too, I've upped the RAM volts to just over 1.6 again and seems a bit more stable.
Bit more tweaking and 4.7ghz was pretty easy as well, 1.35v and below 60 degrees running prime. Very impressed with the chips performance and reasonably low temps for such a beefy CPU. The Samsung greens seem to play well with the x79a-gd65, 4.8ghz is next
I have 64GB of said RAM, anything beyond the XMP profile results in no post on a R4E. I needed to update the BIOS out of the box to sort post using stock RAM settings. I have settled for stock RAM and 4.5GHZ.
I have had bad experiences with over-volting memory in the past, they are much more fragile than Intel CPUs when it comes to volts.
8Pack from this forum has got 5.5GHZ out of his but I do wonder how many chips you would have to go through/cooling/risks to get that type of bench.

Edit: Whoops didn't read above posts, sorry.
Edit2: It doesn't say on the website o.O

Just got my c2 3930k up and running, very pleased and straight in at 4.6ghz 1.28v. Not tweaked anything yet though so tons in the tank
How are you getting your volts so low?
I have been playing around tonight and admitedly Im a noob at this but I can't get anywhere near that..
So far on a R4E board
BCLK set to 125.000
Multi = 36 (can boot into windows on 38 but at insane volts
)CPU LLC set to auto
VCSSA LLC set to auto
I tried both LLC settings at high at first, but that gave me a vcore of 1.43V (extreme gave me 1.5V
)Then I set them to regular, gave me a vcore 1.41V
setting them back to auto gives me 1.408 - still not good
What settings do i need to loook at to bring the vcore down so I can start trying to balance my overclock vs vcore?
