edit: I just noticed you have 2400Mhz memory, yet you indicate it is at 1600. How did you set your memory timings? Have you tried upping the memory voltage and using the XMP timings? Just curious if this is related.

Dan - I turned XMP ON (Profile 1) it was 2400MHz @ 1.65v
Stock voltage is 1.5 and 1.6 max
I thought maybe it was putting too much load on memory with 1.65v which is making OC unstable, so I manually clocked it down to 1600MHz @1.5v

I will try that right after this post smile.gif

Thanks guys

Here are my BIOS settings if experts can take a look and suggest how to go higher with my OC
Setup: i5 4690K - GA Z97X UD3H BK - Hyper evo 212 - Corsair Vengeance Pro 8x2 (2400Mhz)

Thanks! smile.gif

That's exactly how. When done with single fft size testing, I run this for a few hours: Warning: Spoiler! (Click to show)
Blend/ just large or small ffts are not effective in testing.

When using 28.7, you can insert the following line into local.txt:
CpuSupportsFMA3=0
More stressful than 27.9, but doesn't cook your chip with FMA3 ffts. For my intents and purposes, 27.9 is more than enough.

@aerotracks, thanks !

Yes, I am aware of these commands into the local.txt but I never use Prime95 for stability testing. I prefer the x264 V2.06 with the latest binaries. I used Prime95 a bit the last couple of day to test my CPU cooler a bit. One last inquiry...

Those who suggest setting it to an X amount of RAM, how do they mean it?

When I try to set this:



It does not work.

Setting the "Memory to use" works only if "Run FFTs in-place" remains unchecked.

So, which is the best way? To run FFTs in-place or to set a big amount of Memory to use?


I ask all this just for my general knowledge. I do not use Prime95 to test stability.

Thank you.

In-place will be more stressful on the CPU, filling memory is not necessary to check your CPU. For memory stability, it's better to use memtest or a couple hours of fft size 800k without the in-place box ticked & filled memory.

Single fft size testing in Prime95 lets you single out specific voltages of the CPU such as cache, input voltage, imc etc., which is something the x264 stress test can't do.

I see, very interesting!

Yes, when I o/c-ed my RAM I used that MemTest which you open many instances of, like 8 for my CPU? I do not recall its name now, but that was what I used to test stability of my DRAM. It run for hours...

Anyway, as I said, I always use the x264 V2.06 with the latest binaries smile.gif

It is very interesting what you say, though, so could you please list the FFTs sizes for each one of those you mentioned? smile.gif Or can you link to a page with specific instructions? Like, for example, how should Prime95 be set if you seek stability of your Uncore V or the CPU Input voltage?

Anyway, sorry if I bother you smile.gif , personally I do not care at all, absolutely at all, because the x264 is enough for me and this has been proven to me by all the months I use my computer for hours every day, doing all what I like / need / have to do, and it has never-ever-ever given me any kind of trouble in any of my four o/c profiles. smile.gif

You could help some other people though, and even I could give something a try. Honestly, the "bad" thing that Prime does is that it says to me: "You need more voltage"... NO, I do not ! biggrin.gif

Yeah, the higher you go with frequency the more prime95 becomes just a check of your cooling. 4800 for me is last sensible clock speed for this, above it's unnecessary torture.
For the fft sizes, 448k for input, 512k for cache, before running these be 30mins 1344k stable first.

With memtest, use one instance per thread.. so 8 for 4790k is right smile.gif

Great! I assume you mean all of these with FFTs in-place = 15 minutes, right?

For example, for the CPU Input voltage, to be set like this:




To be "1344 - stable" first, though, it means that you should already have set the high Vcore Prime95 is demanding... So, no use for me.

Thank you very much, + REP thumb.gif

Ok, so after stress testing, what would be the best way to set up power saving features? Adaptive with c states on auto with the other stuff just enabled or forget adaptive and enable C7 and enanle the other stuff? Override is something to consider??

Yep, 2x15mins is what I shoot for.

First, reset BIOS...

Now the BIOS should be set to the basic settings, which, usually are the power saving ones...

Restart the rig and go into BIOS... Choose whatever additional settings you may need, and save it as Profile 1...

This way, you can always reset quickly, when you want to... thumb.gif
