I got nowhere until VCCIO was added. I was trying for a while to get 2133, but no matter how far I loosened the timings, even to 13 (which probably has diminishing returns at that point) I couldnt get stable. 1866 at these specs is a good number to me. Granted, added VCCIO made add 1 or 2 degrees onto your load temps, but if you want stability with 16gb ram, you may need it. Leave everything as is, take out two sticks, and see where you test. That will tell you right away if it was ram causing the worker failures. Let me know

Ah nice. +rep for that explanation. I didn't have to up mine, but I'm running my sticks at stock, but this is great to remember for when I decide to try OCing them.

Well what I meant was that by virtue of overloading the DIMMS that much you may actually need VCCIO at stock speeds. Try that. The more memory, the more stress on the other components, for probably, not too much gain. Unless of course you run servers and photoshop/CAD and such

f you have an SSD, disabling them can cripple SSD performance.
How would I tighten LLC up? The only options for it is auto-enabled-disabled.
Don't have an SSD yet, one piece at a time.

You may want to look into adding VCCIO to 1.12 or thereabouts because you are running a substantial amount of ram., which may also require a ram voltage bump as well.

I also see your doing some wierd stuff with the turbo core ratio. You may as well set it to all cores because you will get negligible to no difference doing what your trying to do there. I have fussed with scaling the turbo cores and it never worked for me. Although in about 10 minutes someone will probably jump in telling me Im wrong. Try settings turbo ratio to all cores, leaving voltage where you last tested moderatlely well, and raise your VCCIO up through 1.14 or so, and see where it works. Have you used intel burn test at all?
Ram is 4x4GB. I haven't changed any RAM timings. The only things I"ve touched in BIOS so far is multiplier and voltages.
As for the turbo core stuff, I haven't touched it. That's what it was like at default. I went and rechecked the guide by Sin0822 he actually recommended disabling it (which I missed) so I'll go back and change that.

If on Auto you find your load voltage is considerably lower than your idle voltage then set it to enabled and check the difference again. That's not to say you will need LLC to be stable, you just need to make sure your load voltage is where you need it to be. LLC can help get a grip on vdroop though rather than just chucking more voltage at it.

So if I see idle voltage that is as high, or higher, than my load voltage then I should enable it?

edit: I just wanted to thank everyone who has chimed in on this thread. I've worked with computers for a while and I've always been intimidated by overclocking so this first time has been really daunting. Your input and suggestions have been put to good use and I'm just really glad that a community like this exists.

I see a certain amount of droop as a good thing (unlike the wife boom boom) but if Auto means no LLC and your idle voltage is considerably higher than your load voltage rather than chucking more and more voltage at it to get stable at load you may want to try and enable it. All LLC will do is lessen the gap between load voltage and idle voltage.

Well, you have a 2500k so I would not be running it at full speed all the time. Make use of the speedstep technology and let the thing downclock/use the offset voltage. Im sure that the feature of the chip staying downclocked during idle will significantly extend the life of these processors, unlike my 1090t which I burned out in less than a year.

I'm actually doing that right now. The system has been stable all day so I'm going to enable the C states and boot it back up. Then a quick 10 minute prime to make sure the multiplier is actually fluctuating like it should and there are no sudden voltage spikes. Then going on for the night. Wish me luck.
