yea, i have found that i need to fiddle with both LLC and offset to get where i want the v-core to end up at under CPU load.

but i haven't messed around too much overclocking my system yet, only to 4.3Ghz at 1.264 core so far

At 4.7 it is but at 4.8 it's a little shakey, still in testing phase.

My chip is good for 4.7 24/7 and 4.8 for benchmarks which is more then enough for me. I find clearing my cmos n choosing my saved overclock profile works best to bring those temps down n while it runs with low vcore it's great. The comment above is true LLC is a huge factor.

By the way guys, does it worth to play with Bclk?

It looks like if i'm stable at 101 bclk with same vcore i need for 100 (need more tests anyway) .. and it results in 4746 mhz rather than 4700.

vcore too high.. not stable to maintain the stability

What?

Offset is confusing. I've set 0.020+ offset and it's taking me to 1.28v which is what I want. Does it vary from CPU to CPU? I've never bothered touching LLC as with my balls-to-wall overclocks I just set the Vcore / VCCSA I want and away I go.

If you're going to run a 24/7 overclock, I would try to get it to work in offset mode. So, when it's idling it want be feeding it a constant voltage. It is a little harder to get stable, but worth it in my opinion.

Hello everyone!

I'm sure the following information request, has been asked, and answered; probably multiple times, but unfortunately I'm operating under some restrictive time constraints and I didn't have the time to read every post in this, or other threads, so....

Could someone either describe to me, or direct me too an existing post, for a 24/7 good, reliable, conservative, say, 4.2 Ghz OC for the i7 4930K?

My current GPU-Z and rig description are in my signature.

What I'm looking for is a 24/7 OC that will not cause my rig to catch fire, and die. devil.gif

Seriously though; if 4.2 Ghz is an unreasonable 24/7 OC then tell me what would be reasonable please. I do not want to damage the chip, as I just built this rig, and I won't be able to afford a replacement for some time.

I would like to add/note, that I'm currently, running 8 X 4GB Kingston Beast 2400 MHz DIMM's for a total of 32GB memory. I'm running said memory in the 2133 XMP profile. The clocks are set at the following:




As I understand it, I'll have to manually enter my memory timings when I OC the CPU, as XMP on the RIVE BE is not compatible for OCing. Is this true, or am I just doing it wrong?

Anyway, thank you for taking the time to read my post, and for your patience in dealing with my sorry noob butt! I do have a basic understanding of the principles involved in OCing, but I would appreciate it if any responses are dumbed down, so even an idiot like me can understand. drool.gif

Nice rig smile.gif

I have similar stuff as you and I've been doing a lot of testing of my system. My conclusion is more or less the same as what I recently read from a very experienced Oc'er, that being the best Power/Performance OC is @4.4Ghz. He states that's good for most chips 24/7 provided it can be run under 1.35V and 75C.

From my experience with former I5, which I ran @1.3V for 4 years and temps around 75-80C, I can confirm that those CPU's can handle this without a problem (it still works fine). Yes, it did catch fire (almost), but that was a display melt rolleyes.gif

So, 4.2Ghz @1.2-1.25V should be a walk in the park thumb.gif

These are my manual settings using AI Suite 3:
4.4Ghz@ 1.31V for Gaming/benching and 60 minutes stable in Prime95 with 2133Mhz RAM 11-12-11-30-2
3.4Ghz@ 1.17V for Internet/video/ daily use

Most of the settings on my Asus X-79Deluxe are @ Auto, besides Vcore en DramV. I tweaked my Digi+ Powercontrol a lot to get the lowest possible voltages stable in Prime95. When you use Offset, that will be a different story...

About your XMP profile, that should also work when you OC your CPU and you need to use it because of the other settings that comes along with XMP (a.o.DRAM/VCCSA). Maybe RIVE BE only wants you to consider changing the timings when overclocking, did you look it up in the manual?

BTW: 32 GB RAM @2133Mhz @4.2Ghz may or may not be stable in Prime95. This chip is guaranteed for 1833 RAM @3.9Ghz. Mine does not run 16GB RAM @2133Mhz @4.5Ghz stable in Prime.

These chips can generally do 4.4 with no problem, so 4.2 is pretty conservative. You can probably just set your multiplier to x42, set vcore to offset mode +.02 and should be all set. Leave everything else on 'Auto'.

That will get you started and should most likely be stable right outta the gate. Once you get that locked down, then you can look into how to optimize your vcore, tweak your ram speed/timings, etc.
