gigabyte z87x-oc board

I wouldn't mind some advice on this also I am using a Asus maximus vi formula. Just switched from AMD so everythings changed

I have a guide for a 4770k on this board. Clocking will be very similar but stable at lower voltages. It ranges for overly in depth to straight forward, easy to input settings.

As for the Asus board, there is a topic on 8Packs forum about 4770k clocking on asus boards, the settings should be similar but with lower voltages. You can use the Gigabyte guide i linked but Asus name a few settings differently.

You have a lot more options in your bios than my Z87-A does but i posted all my settings for 4.4Ghz in another thread that might be ok for you to work upwards from. See here.

I have the same board as DMF, albeit with an i7 cpu. The formula does indeed have more options. But tbh you don't need to mess with any of them when oc'ing. Input voltage, vcore and the chipset voltages are all ive had to change, ram on xmp.

What did you set for your voltages?

Ill post my settings up later, currently away from home so no access to my pc.

I am testing my CPU 4.5 is my sweet spot @ 1.25v once I go over I start to need more and more (v) going to 4.6 which is stable at 1.31v

4.4 using 1.2v with LLC to 1.216v

Next I am going to work on my core cache from 38 to 42

setter · 26 Mar 2014 at 15:48

My vcore is 1.2675 in bios, ioa/d and sa at 1.15, input voltage of 1.800.

You have got a nice chip there, much better than mine with the voltage too. On mine i needed 1.170v cache voltage for 42x, 1.20v for 43x, 1.26v for 44x and 1.30v for 45x.

Going to have to do this all over again soon as i have got a Maximus VI Hero for a cracking price.

setter · 26 Mar 2014 at 18:56

Very nice pasty, hero is a nice board too. @DMF, 1.25v for 4.5ghz is pretty ok.

I love to push the chips I get and see how far they will go but for 4.4Ghz @ 1.2V I wonder if its worth it.
I can set 1.2V manual and my LLC takes it to 1.216V

What do you think?

What would you recommend on water

Also my cache is @ 38 with stock voltage, Whats the maximum safe voltage for this & the VID under water?

setter · 26 Mar 2014 at 22:41

Vcore, going by 8 Pack's reccomendations, your fine at upto 1.3 for 24/7 use. Cache, 1.35-1.4v. Some good info in that sub forum. Id link a few threads but unfortunately im browsing on my phone as my two systems have been dismantled.

Thanks I will have a search

Just had another OC after upgrading my bios and losing all settings, I have went for 4.4Ghz at 1.23V with this I can get my core cache @ a 1to1 ratio 44

setter · 13 Aug 2014 at 22:52

Nice update, and good going on the 1-1 ratio with cache. 4.4 is plenty tbh, ive since moved to a 4790k that i run at stock at present. Handles my gaming needs fine.
