Hey guys,

I purchased myself a brand spanking new GTX780 earlier in the week and decided it was a real shame to keep it in my aging i5 750 rig so I decided to buy myself the following:

Intel i7 4770K Cpu
Gigabyte Z87X-OC Mobo
8GB Kingston Ram (the same stuff available in the bundles)

It will be really nice to have my SSD's running full bandwith, and I am hoping to see nice gains in heavy photo shop use with this rig! I use my PC for development as well as games so I think I made a good move.

Anyway, I already have an alpenföhn k2 mount doom, and my question is, what clockspeed and voltage should I be aiming for?

I am a noob overclocker by the way, but I did manage to overclock my i5 750 to 3.8ghz with little hassle.

With Haswell boards is it a case of adjusting the multiplier and base-clock like with my old i5 750?


Many thanks for any help! :)
 
I also have this board but a 4670k I am 100% sure I have seen 4770k preset overclocks upto 4.8. I would keep a eye on the voltage though, 1.25 vcore seems to be the max for us on high end air cooling apparently.

Also interested in a 4.6 overclock stable in my game not prime.

I read somewhere that its a good idea to set your vcore to 1.25 and see how far you can up the clockspeed, is this generally accepted as a good idea?

Also I really need to know if Haswell uses the multiplier / base-clock set up that im used too or is it different?
 
I can't really comment as I am a new Intel user. I set my vcore only to 1.25 and that is all, I changed my multiplyer from 46 downwards and was stable at 4.2. I think I need to set load line calibration to extreme or whatever is highest but I could not find it. I read its called vrin or something along those lines in bios.

Playing my game the temps are max 54c and my game is CPU intensive.

I will try and find the Asus haswell guide.

On my mobile at the moment.
 
It's a overclock guide but Asus has figures on finding how good your haswell chip is, nothing specific to asus or any other brand motherboard.
 
I am not stress testing with prime or aida I just play a couple of hours on guild wars 2 on max. Guild wars is the only thing used so no need to be 100% stable on 100% load when I will never use that amount.

I will try for 4.6 tonight but I think I have a lower percentile CPU :-/.

Ahh i see. To be honest as long as my clock is high enought to open up my GTX780 beasty Im happy ;)
 
I went from a AMD 3 core at 3.6 overclock with 20 fps to the haswell 4670k at 4.2 overclock 70 - 100 fps :-). Same setup just different cpu - motherboard - psu.
 
I have a old 6970 2gb but i have 3 all together, I have 1 installed at the moment.

I need to buy aftermarket coolers for 2 as they run at 90c under full load so just waiting for funds.
 
Have the same setup as the OP only difference is have 16gig of 1866 vengeance (2x8gig). Will be going watercooled. My 780MSI gamer has the heat sink removed, awaiting the EK block. Going to set it up in my L ion case first as I am waiting for the ne Phantek case to arrive (September). I am aiming for 4.8/5.0 silicon permitting

I was going to buy 16GB of ram but as it turned out I spent over £1100 on PC components this week and id run out of money :p
