hello 8pack after you gave me so much help ocing my x79, i knew where to come when it comes to my newly aquired 4770k and gigabyte OC board, id ideally like to get 4.4 or .4.6ghz but the bios and features are a lot different instrust me please oh wise one :) ive read a few guides but its like chinese to me lol

I have got it to boot at 4.4ghz with the settings you mentioned in another thread

multi 44
vcore 1.25
cache 1.15 (which on the OC board is cpu ring voltage?)
llc to extreme
sa + 0.15
IOD +0.2
IOA +0.2

It boots to widnows fine but as soon as I do anything stressful it bsod's, so I tried vcore to 1.3v and it still bsoded im unsure of what to fiddle with to make it stable any suggestions?

Alright mate, check again leaving vring on auto if cache multi is still stock (auto).

Haswell can be a bit picky with voltages sometimes (too much/too little) so make small adjustments at a time. 1.25v->1.3v is a bit of a jump. Increase vcore by .01v from 1.25v upwards, if still no joy set input voltage to 1.85v and try again. It might boot in no bother at 1.25v but if that's borderline to boot it'll need a bit more vcore to stabilise.

x264 benchmark is a good tool for getting it stable, doesn't take long to run, doesn't hammer the core and allows you to see progress when adjusting a voltage with regards to hitting stable. Once stable in this just add a touch of vcore and you should be good 24/7.
 
I know its a bit of a jump but I figured since it booted it may just have been a voltage issue so If it worked at 1.3 I would have back tracked to find my lowest voltage

0x00000124 00000000`00000000 fffffa80`073c88f8 00000000`00000000 00000000`00000000
 
124 can be one of several setting on Haswell sadly so its not clear which one it is.
Vcore, Vring and SA are usually the ones to focus on. With OC board leave all these apart from Vcore at AUTO to start with as a base and only adjust core.
 
From my experience 124 is more than likely related to uncore/ring. As Pack mentioned put vring back to auto (along with SA/IOA/IOD) as there's a high chance that'll sort things out.

Giving vcore a big kick up the backside can work against you as it work's in tandem with input voltage. (vring does as well but not to the same extent as vcore).

It's always better to move up the way than throw in a big voltage and work down, especially if running under 100% load when stressing.
 
Debatable that one. Not sure on Pack's thoughts on this (would also like to hear) but in my opinion it's not a hard and fast rule. Higher core clock tends to yield a lot more gain, the higher the core clock in terms of what the chips capable of the harder it is to raise uncore side by side.

i.e, i run 50/43 for 'daily' duties but could easily drop core down a couple of multi's and raise uncore. Performance wise i'd see a drop. Uncore does help but not in any way you'd notice day to day, benching yes when you can see the scores change!

My advice would be to get core to where you want it then raise uncore towards core multi and call it a day when the OC becomes a little tick to stabilise. For most chips getting them within 300mhz or less of each other should be relatively easy.
 
Depends on task your doing to be honest.

In tasks requiring high bandwidth Uncore makes a large difference. In my experience 3 multi down from core is fine for performance and stability. Start with stock though. Dial in core, then memory and then move up uncore.
 
I've trying to get my head round intel and haswell overclocking coming from an fx8350 it seems more complicated with more options and discriptions in the bios.
I'm using the gigabyte oc board and I'm struggling to get 4.4 stable at 1.285v that's just changing multi to 44 and increasing volts on core above that am lost.
 
Gigabyte OC is a very good board for Overclocking Haswell. What cooling you using??

For 4.4
Set XMP
Vcore 1.25v
Cache volts 1.1
all others on AUTO and test.

If its not stable for your tasks try 4.3

Monitor temps as you stress the CPU.
