So I've started overclocking my 4770k

I reached 4.4Ghz on 1.250v but haven't run AIDA64 yet.

I'm aiming towards 4.5 or 4.6Ghz

 

I've only increased the multiplier and the voltage. 

 

Here are my questions:

 

1. What voltages are safe and good for daily usage?

 

2. Should I set my RAM to 1600Mhz when overclocking? (Its a 1866 kit)

 

3. Here are screenshots of my BIOS. What do I need to set/change? There should be more than just the Vcore and the multiplier.

Thanks :D

Thanks. Now all I need now is the correct settings for the BIOS.

to answer your questions
 
(1) safe voltages
 
 
 
 
0V-1.3V For people concerned about volts\heat. up to 1.3V is playing it SAFE. be happy with your clocks at 1.3V. using an air cooler. I have found that up to 1.3V will offer the best performance ratio in terms of GHz\Watt
 
1.3V-1.44V Still safe without risking CPU degradation . Requires a good cooling solution ( top notch AIO cooler) NOT recommended for people using air cooling or people concerned with heat or volts applied
 
1.45V and Higher. For extreme Overclockers only. from my testing going over 1.45V to achieve higher clock speeds is pointless. the performance\Watt drops heavily and massive amounts of heat is generated.
 
(2) Memory

 

yes run your mem at 1333 or 1600 till you find cpu stability for more than 8 hours. then try bringing the mem chips back up to stock and beyond.

 

 

 

(3) bios changes

 

for my best overclocks (excluding memory) heres what I changed (examples)

 

multiplier 46

 

ring bus frequency 4500MHz

 

Vcore 1.35V

 

ring bus Vcore 1.3V

 

Processor Input Voltage 1.9V

I also strongly suggest using the Intel Extreme Tuning Utility to stress test your Haswell CPU. minimum 8-24 hours.

Aida64 is good, its validated for haswell, a strong second choice in my opinion, but i find IETU much better

Here is what I've changed so far. I didn't know what you meant by "ring bus" but I just used "ring"

 

CPU Ratio/Multiplier = 46

 

RAM is at 1600Mhz

 

CPU Voltage Mode = Adaptive

 

CPU Voltage = 1.35v

 

CPU Ring Voltage = 1.3v\

 

Adjusting Ring Ratio = 45 (4500Mhz)

 

It is currently stable enough to send this message. Any more tips before I start the stress tests? 

 

I don't see Processor Input Voltage anywhere in my BIOS.

Processor input Voltage is VCCIN

what cooler are you using?

 

report back with temps after 15min of stress testing.

I'm using the h100i

 

PC crashed about 15 secs after test. Temps were about 83 Celsius.

 

What about Voltage Offset? I have it to +0.060v

drop the cpu ring bus back down to 3900MHz

you want to try and maintain a 1:1 ring bus ratio.

 

get it as high as 4500MHz for 4.5GHz. Take the highest ratio you can get.

 

you may try increasing the ring voltage as well. it is typically suggested to run the ring voltage NO HIGHER than your cpu Vcore. in your instance running a ring voltage of 1.33V or lower is acceptable.

 

What are your temps at 1.33V?

Temps at peak were 81-83 Minimum were 72-74

Very acceptable.

I've run the stresstests on 4.6Ghz @ 1.385V

Temps maxed out at 95 degrees and had a 85 degrees minimum.

Do you think it would be better just to stick with 4.5Ghz?

My SP120s will be coming in on Monday so the temps will go down. A little.

honestly Im personally fine with higher temps as long as my CPU does NOT throttle down. Typically at 94c-or higher your cpu should throttle down to protect itself.

 

It is in your best interest to keep an overclocked cpu below 85c.

 

right now ambient temps are hot in North America so you might want to settle with a slightly less aggressive OC in the summer and kick it up in the winter.

DO NOT RUN prime 95 with your Vcore set to "adaptive mode"

 

You should stay away from Prime95...OK

FURMARK tests gpu stability.

 

the only reason you would want to run Furmark and stress test your cpu at the same time is to test what your max  temps are in a case with the side panel on

 

thats it.

 

 

no need to run both. focus on getting your cpu stable first
