i7 3820 - 4820 Overclock Club - Page 40

Hey guys, I'm having a bit of difficulty with stability past around 17 hours (the screen shot failed after around 5 hours, but with some changes I've had it to 17). Currently my settings are BCLK 100 and multiplier of 44. DDR3 is at the 2133 XMP 2 profile. My VCORE is at an offset of -0.010 and my VCCSA is at an offset of +0.010. CPU LLC @ Medium with a current capacity of 110%. VCCSA LLC @ Regular with a current capacity of 110%. I've also set my duty control and my power phase control to "Extreme".

Right now I'm benching with a VCORE of -0.005 and a VCCSA that's been manually set to 1.1 to see where that takes me, but I'm starting to get frustrated with this over clock, as it's kinda hard to pin down with it taking so long to fail. Any help would be appreciated.

BTW: Cooler = H100
Board = Sabertooth X79
RAM = GSKill PC3 17000

Sneaky can I ask why you need stability at 100% load for over 17 hours? In what scenario other than running P95 would you be putting your PC under that much stress for that long?

I've asked myself the same question to tell you the truth, but I'm just looking for 100% stability. I thought I had it, after 8 hours of prime after the initial OC, but then Civ 5 crashed after 5 or 6 hours on me one night, so I started testing more aggressively. 24hours is what I've decided I should be able to do without failing a worker.

I find what constitutes 'stability' is different depending on who you ask. To some people, it's not stable unless it can run for week straight on P95 but in my opinion your PC is stable when you run it for what you want to use it for for any length of time (which is never 100% constant load in reality).

The other thing with super long benchmarking is the chances of a non-OCing crash giving false positives with the only way to test it is to re-run another 17 hour test. I've used 1000s of PC over the years, the vast majority of which aren't overclocked yet have had loads crash, lock up or freeze on me but not all crashes are due to overstressed or heated CPU.

Let us know if you manage that elusive 24hr benchmark though mate.

You beat me to it Esteban...I was going to say pretty much the same thing. If you ran Prime stable for almost an entire day then there's no way a game caused your crash. This is just my opinion but I'm pretty sure it wasn't a CPU voltage or heat related crash. It would be more likely caused by the GPU or PSU in my opinion, your OC is probably just fine. Really tough to tell though.

Aren't the requirements for getting into the stable club 24 hours?

you want to get 24hrs of stable stress testing at 4.3ghz? what a waste of time, shoot for 4.5+ at least if your going to waste that much time and CPU degredation, you could probly get a i3 2300k to go 4.3ghz lol ......just my opinion though

well its called "stress testing" right? so sitting there repeatedly trying to get 24hrs stable is going to degrade your cpu at a increased rate, same as if you sat there playing BF3 for 24hrs staright, or video encoded 24/7, folding at home etc. except these thing may or may not 100% your cpu, stress testing does. right?

sitting in your car with the peddle to the mat in neutral is gonna pop your engine alot quicker than if you just driving the **** out of it
