Come watch me overclock my new system
- Thread starter metigue
- Start date
I'm sure I can get this at a lower voltage, I'm going to downvolt a bit and re-run to try and get it colder.
Prime95 needs to be run for hours, not minutes, to prove stability.
2 laps of Prime95 isn't enough to call stable (that isn't even enough to see max temps). Generally, you need 8 hours - some people prefer 24 hours to call a system stable, but imho 8 is enough.
As for your temps, ideally you shouldn't be going above 75C.

Ok well, I'm running 8 hours of prime95 on my 1.42 volt boot, as it was displaying temps in the low 60s at the start, I'll post results in the morning
EDIT: Ran for 30 minutes then prime95 crashed, highest temps were high 60s, seemed pretty stable, I don't want to thrash my graphics card so I'll end there.
So perhaps not confirmed 5 ghz for you, but I'm keeping this OC for every day use, it's 5 ghz for me

You'll change your mind when it keeps BSOD'ing while you play games, or do work, or even maybe browse.

How is crashing after 30 minutes of Prime95 "pretty stable"?
Enjoy your BSOD's.
Stick it on 50 IBT runs at a high custom, then come back and show us it stable.
In my experience even an 8 hour prime stable can crash and burn after a few IBT runs.
Btw, your secret to low temps @ 1.6ghz is just intel speedstep kicking in, it reduces the multiplier when the system isn't under load, then increases the multiplier when required.
The idle temps are good, but I would bet thats just due to low ambient temps from a cold boot, I've seen mine at 19c from a cold boot. The load temps are not so good, but it depends what temp your comfortable with, the max temp of the chip is 98c, it hits that the system will shut down.

I've been playing games for like the last 4 hours straight, CPU temps haven't hit near 70, and I also kept sress testing it as I was downvolting it which took about an hour.
It just seems stable to me.
I'm not new to this, I've overclocked a ton of rigs before, but this motherboard is completely different. It's very weird to clock, took me a few hours just to find out how to do it manually.
Also, I've never heard of torture testing a CPU for 8 hours to test stability, I was always told 30 minutes + is generally fine provided you don't have any dangerous temps.

If it seems stable then go with it, but you can't say you haven't been told if/when the hang ups arrive.
Also it depends what games you playing, the majority of games are only optimised for 2-4 threads at best, grab something that will hammer all 8 threads and see how it fairs up after a few hours.
If you want that voltage lower you should be ideally playing around with the voltage offset rather than a static vcore or auto settings.

Yeah, It took me an age to find the switches that let me set everything manually on the motherboard, but I've got it now, 1.416 is what I'm running my 5 ghz on atm, and I'm torture testing it for 8 hours as we speak, -.- I guess I'm a sucker for peer pressure,
Playing games while torture testing not advised?
EDIT: BSOD when loading up crysis, upping voltage and trying again.
EDIT2: BSOD 4 minutes into playing crysis with 1.424

Run IBT, stresses the CPU far more than prime in a shorter time period.
Run it on high setting with 5 runs, that will give you an idea of stability. If you want to prove stability, 50 runs on max settings.
If it dies anywhere on IBT, clock isnt safe and you can potentially screw the CPU.
But +1 to the Asus boards being a pain to OC on. I cant find it anywhere to OC the base clock, only turbo (which Ive read in loads of places that it isnt safe). Ive tried turning off the auto offset and manually doing it, but it wont even boot....auto voltage is [email protected], if I try manually [email protected], it wont boot.
Ah I've got the hang of mine now, you just go to main settings, CPU settings, and disable turbo. xD
If your going fully manual it helps to change LLC/Phase etc... as well.
For me im stable with a U High LLC, but unstable with a 'high' LLC.
Theres plenty of good guides about for asus p67/z68 boards to show what settings you should and shouldn't have active.
Unless you have a really good chip, you should maybe be looking to start around 1.46v for 5ghz, check thats stable then work your way back

Yeah, I'm restarting from 3.4 using IBT, as before I was overclocking the turbo.
EDIT: at 4.5ghz, How do I make IBT max settings? I've put it on max threads and maximum stress and it won't get my temps above 50 degrees

In the stress level drop down, hit custom, then where it says 'available ram' you need to enter something near to that value into the custom box, though you'll want to keep a few hundred mb to one side.
Example, if it says 6400mb available (as mine commonly will with 8gb installed) I tend to put in about 6000mb-6150mb.
Don't run prime AND ibt at the same time, you wont feel the full effect from either program doing that.
