I would say that even if you pass 100 hours in Prime 95 and every other testing software out there you are never 100% stable. Ive had numerous crashes in games when my VCORE was too low albeit stable for stressing programs.

I had hoped to engage in an adult conversation about additional stability tests, but obviously that is not going to happen. Pointless posts of nitpicking single words doesn’t not progress this thread and its intent. I would still be interested to see someone with an ROG mobo and Ivy chip that could pass every stability test then the chip oc fail on normal activity, I guess I will have to wait and see if that ever happens.

To be clear to any people brand new to this, your oc should be checked with stability testing. No one will ever agree on which tests are best, nor how long they should be used. People who care about a higher level of stability will run multiple stress tests for 24 hours. Others who just game and surf can get away with much less if they wish, it is up to the individual person.

I believe the guide here uses a reasonable midpoint of 12 hours of the current Prime95 with 90% ram usage and no Event Viewer occurrences. If you pass that, then spend a week putting your machine through everything you use it for and if it does fine, then you should be ok.

You should recheck if you make any significant changes, like changing bios, hardware, or ocing ram. You should also recheck over time, some may test once a month, others only infrequently, it is again up to the individual user.

Everyone knows there is no such thing as stable, it is a concept and is not achievable. You just try to get stable enough so you have as close to zero problems as possible using the machine the way you do. As a side note from someone who remembers a time before computers, don’t take any of this too seriously. It is just a computer and an oc, this is not open heart surgery on one of your children.

Let's put this simply:
I had prime stable for 24hrs.

After 2 weeks I got BSOD's -> that was due to a failing RAM module (had it replaced)

Then I got P95 24hr stable again, after the replacement, and after folding it crashed within 2hrs.
I upped the voltage by 1 notch and now I'm 24/7 folding stable.

So sure P95 cannot test everything and anything, unlike folding (to some extent) - however it does determine 90%+ stability at 100% load, and that's better than most benchmarking/stress testing software out there (ie IBT, which to me determines 20% stability)

Yep if it can fold, it can hold.

So when I get my PSU back on monday I'm thinking about doing some folding to test for stability (and to help of course). Do I have to do anything to the settings to maximize my stability testing or do I just download it and let it run the way it is?

So I delidded my CPU and I'm shooting for 4.5+ overclocks but my cpu seems to be very power hungry past 4.4. For instance 4.4 only required around 1.2 volts but to go up to just 4.5 I need over 1.3v and even then I have 1 core that quits in the middle of P95 runs however IBT runs without a hitch.

Is this typical for ivy to need such a huge jump in voltage past 4.4? I am wondering if I should be looking elsewhere to get 4.5+ stable other than offset/vcore. Do most people with 4.5+ overclocks still use offset or are they using manual static voltages at that point?

Ivy always has a wall at a certain OC. It is usually higher than 4.5Ghz, but it definetly is possible. My old 3570k needed an ridiculous amount of volts for 4.5Ghz (1.391v). You should try using a fixed voltage with the highest level of LLC to find the stable voltage that you need for the overclock that you want to achieve and then switch over to an offset once you find it.

I totally forgot about the "additional turbo voltage" setting with this board so I've been now utilizing that, I also removed the XMP profile from my RAM (it was 1600 8-8-8-24) and I'm now running it at 1400 MHz with really loose timings (11). So far @ 4.7 I'm IBT and Prime 1344 & 1792 stable. Maybe it's time to pick up some Samsung wonder RAM.


Are these good voltages for 4.7?

So your MB supports additional voltage, other than core manual/offset for turbo only modes ?

What Asus MB you have ?

Oh, that I would say is good OC voltage from what I have seen posted by others .
