Your opinion???

4690k
sabertooth z97
kingston hyper x 1866mhz

overclocked to:
4.6ghz@ 1.14v
cache 40 "auto" voltage
ram 2000mhz "auto" voltage(1.5v bios and cpuz) - timings 11-13-13
digi+ control: cpu load line calibration to "level 4" because on auto game me high temps on VRM

tested with xtu (1.30 hours) & aida (1h)
pcmark8 passed
realbench benchmark passed
superpi 32m passed

What were your temps ? If temps are good that chip can prolly do 4.8 around 1.25v or lower. !.25v is still on the conservative side for DC. its a nice clocker anyways.. thumb.gif

Overall looks good. What temps were you seeing during the testing and what are you cooling it with?

I get 65-68 when running aida. I only get max 81 when running intel burn test.

Should I leave cache and ram as I mentioned in my first post?

I will try tomorrow run aida @ 4.8 with 1.18v which I tried and I login windows successfully.
post #5 of 15
My opinion? Not a chance that chip is stable at that voltage with that frequency. Can you get into windows and play some games sure. Will you run the risk of data corruption probably. Personally even if a chip passes a 24 hour prime test still does not mean that chip is 100% stable at that clock. But its a really good start.

I think over clocking with low voltage is fun to see what you can do. But I would not run those volts/frequency for everyday stability as one BSOD can reek havoc on your data. But thats just me smile.gif

So if I increase at 1.15v volt you think I could reduce such risk?
post #7 of 15
It would be best to see what is and what is not stable and make adjustment from there. If you want true stability you need to run any test you can find that will give you a worst case scenario. A what if this happens would the cpu remain stable. It is not like i can say exactly what voltage your cpu will require because of many variable i do not know. What i can tell you is that typicaly a 4.6Ghz requires around 1.35 or more vcore to remain stable. So unless you have removed our IHS and or lowered your ambient temperatures it is very likely your cpu is not "stable" at 1.15vcore.

What i would do is some work load your pc might normally see plus doing a couple of threads on prime95 to give your self a simulated worst case scenario. Then you can add heat to your room to a worst case temp and find what cpu is stable at with warmer room. This will give you some information on what the computer is able and not able to do.

If you find no instability then either increase your cpu speed or lower voltage until you find a unstable clock then add voltage or take away speed to stabilize the system far enough away from the unstable clock that you feel it is safe. IE 4.9Ghz is stable at 1.425vcore but 4.92Ghz is not then i would take away .1Ghz to ensure stability over time so settle for 4.8Ghz at the same 1.425vcore. Do not reduce vcore with frequency you will have nullified your results. This would be safest way to ensure stability.

I read that haswell generally can oc at 45-46 stable, not for such low voltage, but at 1.2-1.25. I have already run many stress tests like aida, xtu, realbench, ibt and benchmarks like pcmark, realbench and cinnebench and everything seems so stable that I'm impressed! I'll let it at these settings at this point and if it is necessary I will increase the voltage.

Its very possible for you to be stable a 4.6 1.15v with a good cpu. thumb.gif Most DC can do between 4.5-4.8 at 1.25v. Some a little better even.

Also go to the haswell OC thead and download x264 bench. Run 50 loops. it runs much cooler than many of those listed stress test and still finds instability better than aida64.

Run 50 loops with 1.14 volt. Perfect! Much cooler than IBT and Prime!

Two more questions:
Cache to 40 with auto voltage or auto freq/volt?
Ram 1866 10-11-10(default) or 2000 11-13-13(oc with auto voltage)?
