Didn't think my i5 would hamper me that much. I couldn't even break 9000 on stock speeds. Is my 1333 RAM hurting at all?

Will ad the FM links on the SLI and quad SLI score later as 3dmark.com seem to have trouble atm.
 
Edit: fixed FM links

Holy crap! What temps are you getting at that clock speed on the CPU on Air cooling?!?

It looks like I had some issues with my setup before.

Great score. Congratulation. Could you be so kind and post your UEFI settings? How much is VCORE max, I thought it's 1.4?
Did you set vcore manually or is it on auto? And did you just take multiplier 50, adjust ram timings, disable EIST and EPU power saving? Or what else.
As you have an ASUS board as well as a C2, isn't the UEFI is basically the same?
I restricted VCORE to 1.3 for safety and did not dare to go further.

@morty
Your vcore is 1.584. Is your 3930X that solid? How do you cool it down with merely air?. Really a monster score.
 
@all
Let's get ready to rumble! Though I hope this will not emerge to a funeral feast including the incineration of our beloved toys.

 
 

*EDIT - New score and screenshot below.

Just saw that a screenshot is needed as well. But I had already closed 3DMark11 so I will run again later and get a screenshot for ya.

I would try if I could do this mod but it's too crazy for me

Thanks. Here are the settings that I am running in UEFI:
 
Base Clock / CPU Strap: 100
Turbo Multiplier: 50x
Memory Frequency: 1600
VCore: 1.5v ( ~ 1.47 under full load)
CPU PLL: 1.8v
DRAM V: 1.5v
EPU Power Savings: Disabled
EIST: Disabled
CPU ClockGen Filter: 20UF
 
I leave pretty much everything else at Auto. This board is very good at automatically setting configuration where needed. I also set base memory timings since I am running tighter base timings than what my memory kit is rated for. The only reason I set PLL and DRAM voltage is because both were higher than needed and I have better stability at these voltages. I sometimes also run a bit higher base clock around 104-105 which the board handles fine and sometimes allows for setting core voltage a bit lower than overclocking by multiplier alone.

Thanks for your detailed answer. As I quoted already the only thing which withdraws me from occing higher is this tutorial which is very well described and helpful for overclocking newbies like me: The VCORE. Every increase over 1.4 could be harmful. So what do you think about this? Aren't you afraid of grilling your lovely i7 3930K C2? And how do you cool it. Mine is Corsair H80.

Here's for the enthusiasts:

So as my score at this time is P10915
my hwbot rank is #193, which is not too bad if I haven't misread this.

And just found the GTX680 rankings, where my rank would be #23:

I don't have screen shots like you were listing, but those are my scores at stock EVGA GTX 680 cards, in SLI.

...will need to do some more testing

I only run these voltages for benching. For 24/7, I run 4.5 GHz at around 1.34v under load mainly because I keep the CPU loaded 24/7. I don't think there is an issue for short term benching at least not that I have seen yet. If anything, I am more concerned about IMC failure than core CPU failure. Out of all the i7s I have pushed to higher frequencies and high voltages while keeping them loaded long-term, I have only ever had one failure and that was with the IMC. Because of that, I keep the memory frequencies and associated voltages at conservative levels.

I am running a H100 which works surprisingly well with this processor at high frequencies provided the fans are turned up enough.

 
Thank you for your advice. I've done a bit of research and used nearly the same UEFI settings. My vcore was 1.35 @4700.
Max CPU temp was about 60°C. How much is yours?
Increasing gpu mem voltage did not help. Contrarily I lowered it and got better results.
Next step will be @4800. But I can tell you that I'm still feel a bit apprehensive... Hope there will not be longterm disadvantages, but - who wonders - I'm not used to this stuff.
What the DDR Voltage concerns I just stick to 1.5V which is default. Unfortunately I've purchased only DDR3 1600 as I could not imagine to come into benching.

why is there such a huge variance on people's shader clocks? you can't even touch those through precision right?
