Hi Guys,
Just bought these 2 4790k and Z97 FTW but still get confusion on OCing of this, so anyone please show the OC instruction !
Thanks Guys !

Its like asking an artist how to paint a painting.
 
Your best bet is to read up and search guides online, and get a basic idea of what your up against before making any changes.
 
It will be similar to your current board.
 
Safe bet is 4.7  = 47 ratio   and a vcore of 1.25 provided you keep using the  Swiftech H20-220 

I skip away from Ocing 2years never touched it since I got z77.
The thing is I disabled all C states but it keep down clock @ 4G and some major stuff need to be adjust to get over4.5 fool me :-)) ! this is the first time I hang around with UEFI bios.
1 more thing I wondered  is this z97 FTW the main board power supply has only one 8 pin instead of 2 , also the eleet doesn't show the memory and Ocing state ?.
So wonder this time evga support doesn't post the Ocing guide for Z97... ???  :-(
Thanks for your answer anyway !

Dude,
I got it works @ 4.5g but can not permanent that steadily ,, when disabled EIST/Turbo it keeps at 4g ! because when I play BF2 I want it stay at highest speed always ! very poor mobo :-(

Hello guys, I don't have the EVGA Z97 board, but I have done 2 OC's on this chipset with the 4790k. What I noticed is that you don't need to mess with the settings too much. Leave as much on auto as possible to get a quick compatibility overclock, than start changing some things to tweak stability. For me, the sweet spot was everything on auto, set the ration to 47 (for a 4.7 OC) and set the voltage to 1.28 - 1.3 and see if it boots, and if it does what temp is it putting out and if it's stable.
 
I can't stress enough to be sure to have the latest bios update, and always always always reset the bios and load optimized settings after a bios update. Also, be sure to set your ram to MANUAL with MANUAL voltage and MANUAL timings (to whatever your factory default is). If the OC is stable with that voltage start lowering the voltage until you induce instability. Post your results meanwhile I'll look for a tut online for ya.

You don't have to disable EIST or anything else to overclock. The 4790k is really picky from my experience, so try what I said. I don't own this motherboard, but looking at the manuals, you go to the overclock tab, set the "CPU Multiplier Control" to manual, and set "CPU Multiplier Setting", Core "1 - 4 Ratio" and the "Non Turbo Ratio Override" to 47 (for a 4.7Ghz OC), leave the "Ring Ratio" on auto. Go to the CPU Voltage Control and set it to override @ 1.27-1.3V (you need to test this yourself).
 
Again, I don't have this MOBO so I'm not 100% sure on those. Before you try this, reset your bios, load optimized settings and SAVE. Once you restart after saving it, go back into the bios and start you OC. Only OC your CPU for now, and be sure to set the memory to factory timing and voltage (don't rely on XMP profiles).

Thanks a lot guys , will give a try when I get back home from work :-))

At the 'Non Turbo Ratio Override " by default is set at " 40 " , so I cant not set it to " 47 " ( this section only decrease number can not increase over 40 ). So my board has problem  or bios 1.04  ??? am I missing something ?
 

I know this thread is old, but im having the same problem on my z97 classified, any1 found a fix ?
