3930K @ 4.8ghz voltage question

[moonbogg]

OK, so the 3930K is at 4.8ghz using an offset voltage of .05 resulting in a load voltage of about 1.375. My temps during only a few runs of cinebench hit 80c on a couple cores though! I won't be hitting those temps during BF3 i dont think, which is really all I care about. The question is does this voltage seem normal for this chip? I mean, is under 1.4 considered safe? I use power saving features so the chip speed and voltage throttles down when idle, which should help increase lifespan. Thoughts/suggestions please. I think its pretty sweet that I get 4.8 this easy.
When using auto offset voltage, it goes to 1.4v for only a 4.5ghz OC! That auto voltage sucks I think.

Does it BSOD if you lower the voltage?

Your a very lucky man, it takes me 1.355 V to hit 4.5GHz. Its a reasonable voltage to run it at, will probably run for a couple of years before the clock speed degrades.

Pretty similar here; I am at 1.34 for 4.6ghz. Any higher voltage and I see temps get a little uncomfortable with AVX and all cores pegged.

Voltage in sig for 4.7Ghz. Pretty much hit my voltage wall.

I have only begun overclocking my 3930k, but ill report back after I get some stable clocks. I have a feeling I won't have much to play with though, since my load temps are already ~65c at stock

What are you using for cooling? That seems really high.

We don't really know if he's lucky or not without serious stress testing results. Couple runs of Cinebench are hardly that.

You have ~30c room to play with. But yes, six cores generate some heat.

OK I decided to settle with 4.5 since 4.8 got way too hot and needed over 1.4v which I wasn't comfortable with. Heres the new question.
Yesterday I was at 4.5 with a -.01 offset for a load voltage of 1.304. All other settings in bios for voltage are auto except for ram set to 1.5 and CPU curent capability is at 130%. I played BF3 for a few hours at that voltage just fine. I came home today and found the PC wouldn't even boot without a few bumps in voltage to +.005. Is that normal or is this chip already degrading lol? Actually not funny.

I have a good feeling we're going to be seeing a lot of failed chips at this 22nm node as time goes on...

though if Intel is shipping at 1.325v, how much harm could another 0.05v do???
I really don't know.

nah not degrading. No way. Clear CMOS and start over.

Wow, so many low voltages.. I feel silly now having had mine so high.. lol But seriously, if you wanna OC this chip decently, you need good cooling.. Its a massive chip and produces massive heat when upped. And i think those that have the cooling and only see 4.2-4.5ghz are too scared.. Its a performance chip ffs. Man up!

Its hard to man up when $500 is 3 weeks of lunch money

Personally I treat my computer as a disposable item. I am heat bound however due to hot weather.

Yeah true, same with me.. But i do realize that people have different circumstances and budgets.
Im not gonna go on coz it doesn't help the person that posted the thread and may be considered "flaming or trolling" not that i even know what that is. lol

But you need to throw some good cooling at that chip if you want to "OC" it. And really why buy it if your gonna keep it at boring stock levels as this is part of the fun. But you can't expect all this added clock n performance with mediocre cooling. You better of running a 2k chip or something.

Get some better cooling people, thats my opinion.. And boris, u need a phase change chiller.. LOL

 

[FiLeZz]

wake up mods... delete this junk and ban this troll

 

[White_Ice]

I am not a troll, i am a human being so i take offence to that.

I am running gaming and benchmark stable at 4.5 @ 1.35v. Temps doing these tasks hit around 65-67 max. I'm sure something like prime would spike me in the high 70's or low 80's, but honestly I really don't care about prime and I don't do that BOINC crap anymore. If my rig runs without crashing for what I use it for i'm happy.
$500 is a lot for a chip for me. I could go with real water cooling and push it hard, but i'd rather it last me well into the next upgrade cycle if I decide to wait it out for a bit.
I might not be able to shake the upgrade bug until I grab a proper sata3 SSD however. This Vertex 2 is so slooooow lol

Hahaha, Phase change cooler is cool, but i'm not sold on the idea, too many things to go wrong.

Even though I love gadgets. I have an aversion towards complex moving parts.
