5820k overclocking (voltage,multipliers,cache speed and other settings)

post #1 of 8
Thread Starter 
Hello guys, i recently bought a 5820k and i need some overclocking advises from you.

my rig is :
Memory : gskill ripjaws 2400mhz

Motherboard: Asus x99-a/3.1

gpu: 980ti xtreme edition

ssd: m2 type samsung 128gb and sandisk 60gb

psu: corsair RM850i

hdd: 1TB WD

cooler: coolermaster seidon ver2


My cooler is really bad so i ordered a 360lt custom water cooling kit from phobya only for the cpu to get the best overclock i can for daily use. Now my overclock settings are:

4ghz with 1.1vcore voltage (but i can only get 4.2 stable at 1.180 and for some reason when i choose 1.150 my motherboard jumps my voltage at 1.178 all the time?)

cpu cache is at 40 multiplier (min and max) with 1.19 voltage seems good

my agent voltage is: 1.000v

voltage input auto at: 1.92v

my vrms are at extreme

I was hoping to get a nice 4.6ghz or even 4.8ghz overclock but it seems that i am going to reach 4.5ghz :/


So mates what vcore voltage should i use now with the custom watercooling? (i want my cpu to leave about 4-5 years)

agent voltage and generally on all the settings?

Also for stability test i was using prime 95 but i read that is not good for this cpus, either aida64 , so what heavy program should i use?

Thank you for your help and sorry about my bad english!

Because you have custom WC, I would personally limit max voltage to 1.3V, of course assuming temps are fine as well, <80C. Just see what clock you can reach up to that voltage, and I would suggest slowly working your way up just for safety reasons.

As for testing the OC, aida64 is alright if you want to do serious testing. I myself just test my OC's with daily usage and real workloads, but that's just me.

Thanks for your reply , i did a test with aida64 and real bench and i was stable at 4.6ghz at 1.3v with max temps 77 on 2 cores with my poor seidon. In gaming i dont see anything above 60 shouldn't i push it about 1.35-1.4V with the custom loop ?

I have an 5820k oc to 4.6 with around 1.325v. Temps sometimes spikes past 80 but aida does that. On cpu bencharks, i usually hover around the mid 70s. 4.8 is highly unlikely. Just be happy you got to 4.6. I mean, you can try to push to those clocks if your temps allow it. Anything higher than 4.6 is pretty much rare on these x99 chips.

You should go say hello on this thread...
http://www.overclock.net/t/1510388/haswell-e-overclock-leaderboard-owners-club/16910#post_24869643

Is the siedon is a 120mm rad? I'd wait till you get the water cooler setup before testing with overclocks too far above 4ghz.

4.6 at 1.3 is above average for x99.

Yeap, seidon is a 120mm rad , i see some people using 1.4v with that voltage i should be able to reach 4.8ghz but i am aware of the fast degradation :/ . if i am able to stay less than 80c with my seidon at 1.3v then with the 360mm loop i should be able to stay about 60c i will have more headroom for the heat but should i really push my cpu at 1.4v or 1.35?

aida is good for a first test sanity check, if it can pass aida cpu+cache+fpu (+mem) for a few hours move on to tougher tests

aida cache only is good for cache overclock testing

the x265 and x264 video enoding stability tests / benchmark are very good for stability testing, good non-synthetic tests that don't generate too much heat, realbench is good too like that too

hci memtest is good for memory testing

the linux based 'stressapptest' is even better for memory testing

i like occt large data set for the last pass of cpu core testing, it's a synthetic test that's more demanding then those others and it also generates more heat. If it can do 4 hours of occt large data set, that's solid. some people think this one's not necessary, but i like the peace of mind it gives me

cinebench and superpi are good quick running benchmarks to let you know how your doing performance wise

things to avoid
- prime95
- linpack
- ibt with more than the 'standard' stress level

You have right,i will stay away from 1.35 i will try to make it stable at 4.5ghz below 1.3 , is cpu agent voltage 1.048 , input voltage auto at 1.98 safe? Also what is the max cache voltage that i should use? I didn't know about prime95 and i read it before, i run it several times when i bought the cpu but i realised that something was wrong , temps was crazy high and sometimes not stable at all so i switched to real bench then.
