Okay... so... I've sense overclocked my i5 4690K and am running 4GBx4 beyond its factory specs.

Sense then I have noticed something... I seem to be getting a lot of BSOD sense the OC of the 4 4GB sticks that were originally 1866Mhz but i'm pushing them to 2133MHz.

Things i've done to combat this...

Turned off High Precision Timer
Increased DRAM voltage to 1.65V

Still seem to have some issues..

Only other option I've yet to do.. is test each Ram stick individually only because its such a pain with like... 3mm of clearance of my Ram from my CPU Cooler.. >.< Anyone else has some idea's i'm all for it.

In order to run my 1866MHz ram at 2000MHz, I had to up my Dimm voltage from 1.5 to 1.620v.  Also had to up my VSA & VCCIO voltages from stock to 1.220v. 
 
I'm not sure what those last two voltages are called on your board.  VSA could also be something like "IMC" or "VCCSA".  And VCCIO could also be something like "QPI" or "VTT".

I am a strong believer in leaving system RAM at stock speed. Overclocking the RAM almost never nets any noticeable performance difference (unless you care about slightly higher numbers in a benchmark). You pay for overclocking your RAM by reducing the life of your CPU's memory controller, reducing the life of your RAM, and having random annoying system crashes and freezes. Not worth it.

You may have to loosen timings for that kit, setting them to 10-11-10-28 @ 1.6-1.65v should do the trick.
Though, as ty_ger07 said, performance increase from oc'ing would be negligible and probably not worth doing in the long run.

Re: Ram OC instability? 2015/03/01 08:29:59 (permalink)
Here's my perspective on this with my current hardware.
 
1.  My 3820 is a partially unlocked chip.  Will only go up to 4.3GHz.  I prefer 4.5 for my everyday use meaning I need to achieve that with the bclk.  My 3820 is a great OC'er frequency wise, just doesn't have a good mem controller.
2.  My ram is rated at 1866, but because my chip has a very weak memory controller, it won't run at 1866 using manual settings or xmp profiles without an increase of the voltages I mentioned above.
3.  It takes the same voltages for me to run at 1866 as it does at 2000.  My only other option is to run my ram in the 1600 range which still requires a bit more than stock voltages, just not quite as much.
 
So considering this is primarily an enthusiast forum, I offered a possible solution (answer) to the OP to do what he wants with his hardware and not just my own opinion without any attempt at answering his question...
 
Everyone has their own reasons for doing what they want with their hardware...

Blah. Got a BSOD in normal 1866. Pulled my comp apart to test each ram stick individually.

I primarily was doing it for fun, had no issues till i introduced another 8GB of the same set. May end up later selling these for a solid 8GBx2 set later down the line.

Yupi had the timings 10-11-10-28 still got bsod. 0x000000124

Re: Ram OC instability? 2015/03/01 19:12:24 (permalink)
Checked every Ram stick with Memtest v5.01 no issues for each individual ram so I went ahead and re flashed bio's and changed up some settings. We'll see how this goes in time if I get another BSOD.

BSOD Code 0x000000124, Increases your vCore.
Bump it up by .005 at a time or .010

i know there's another word for vcore but cant remember what it is at this second. I'll have to check when I get home.  Appreciate it.

Other than Core or CPU Voltage I am not sure.
Unless you are talking about Offset CPU Voltage, Anyone?

I think that one is more to do with Video than Memory. But I am not sure.

Well seems maybe it was a bad Bio's copy. I redid my bio's version and than ran Intel Burn-in test. No BSOD and I haven't BSOD sense I redid the Bio's flash.

Only time will tell, I haven't had much time to go ahead and play much besides a round of Homeworld 2 Remastered and left my comp to Fold.

no issues so far.

BSOD 124 in most cases less vcore and in rare cases less vdimm.

Then you are saying to Reduce the voltage?

Yes
"less" in most cases means to reduce or lower something.
I have a 100 but you have 90 that is you have less than I do.
Or I am reading your Post incorrectly.
 
I have increased my vCore to correct Code 121 124 and 117 I have never tried to use less voltage is all I am saying.

you reading it incorrectly. you have to increase vcore or vdimm to stabilized what is causing instability.
OP having BSOD 124, cpu or the ram is not stable.

We are reading incorrectly? I think you are writing incorrectly. ;)

"less" != "too little"
"less" == "reduce"

I think you meant to use the word "more" or "increase".
