I have one bum core. Try the per core overclocking. I have a single dog core that doesn't like anything past 4.2.

Hmm how would you go about finding that out.

well my 6800k can only get 4.2 stable and at 1.255 volts anything above 4.2 is unstable no matter how much voltage i give it i agree some brodawell-e chips are not stable after a certain point.if i would have known this i would have gotten a 5820k instead.

i was good at 4.6 @ 1.46 until mass effect came around. had to drop to 4.4 @1.399. such a big jump as i can get away with 1.299 @ 4.2

yea me too my only reason for getting the 6800k was it was on sale on newegg then bundled with the msi board i got saved another 40 and the board was also on sale for 20 off with a 20 mail in rebate. But id try per core clocking like a user above mentiond im testing out overclocking 5 cores at 4300 and 1 at 4200 and made it longer in realbench then i have ever made it.

Didn't think of that.. will sound stupid (is most likely?), but i thought this was only a scenario to consider for core frequency. Didn't know it applied for uncore as well :D

Thank you for pointing it out, lol, though to be honest this isn't a route i was ever willing to take.

 

edit: To add to the irony, disregard the previous value; uncore stable at 3,250 with 1.080 vring so far, apparently it could get even lower. Can't believe that i can't get it to 3,375 with a 0.220 margin available to me :(

i hear u , i see that u even have the same mobo i have. man if i would have known the shi*** oc'ingthat the 6800k was capable of i would have defiantly had gone with the 5820k , in my scenario i just bought it because my previous xeon 2680 v4 cpu clock speed was too low to run some games, didnt matter if it had 14 cores or not. so i sold my xeon on ebay and bought my new 6800k on amazon for 400$. but it was the same exact price for a 5820k. so i just couldnt see myself buying the older architecture for the same exact price. but in hindsight now i wish i would have.

yea same i was hoping for some luck with overclocking but looks like my cpu has 1 bum core im pretty close to getting a stable overclock using 43x on 4 cores 42x on 1 core and 44x on one 1 core with 1.35 vcore still tweaking it.

Do you guys use different (min / max) freq for the cache (and offset voltage)?
I've set a 28 min and 36 max (with an offset like 1.23v in full load) and I still need to work with it to stabilise (the pc freezed after ~90 min of Realbench).
But I can only see the freq going down in idle, the cache voltage remains higher.
I mean, is there any reason not to do a cache setup like that and go for the fixed frequency / manual voltage instead? thinking.gif

my board only lets me set a fixed cache in bios but watching hwinfo64 it does go up and down depending on the load.
