So iv been testing for the past few days on prime95 and ibt
and the farthest i got stable was with:

With these settings i ran IBT for 10 passes on High and passed.
Ran prime95 for 16 hours and passed.
Temps from real temp were Min: 45,44,39,38,45,40 and Max: 78,70,72,79,72,75. usually stayed in high 60s and mid 70's. Unusual?
All stable.
Let me know if i should drop any voltages or changed for these settings if you spot anything :).
 
____________________________________________________________________________________________________________________
Now i  all i did to these settings was changed the multipler to 45. Leave everything else as is and run IBT on high for 10 passes and passed.
Run prime 95, 2 hours in, i get a blue screen with something about missing a clock.
So now i increase:
VCCSA to 1200mv
VSA to 1200 mv.
& leave everything else the same (with 45 as multiplier)
Run IBT on high and passed. Run prime 95, 2 hours in, blue screen again.
So now im lost and seeking any help :). TIA!
 

Well first of all what are you looking for? the highest OC you can get, or a more "optimized" Overclock for 24/7?
 
Because for 100mhz or 200mhz i would preffer to have better temps (lowering the voltages).

You tried 4.4 with a lower Vcore voltage? 1350, 1325, even 1300?
Also VCCIO Intel Max Spec its 1.1, but for some people, raising this value provide stability, i didn't need it. ( I would recommend to leave this @ auto - VSA and VCCIO).
 
I have my CPU 4.2 @ 1,15 Vcore / 50%Vdrop
(Temps - H100, 28 Idle, 58 Max core 30minutes @ OCCT / 6 Hours at Prime)
and also 4.6 @ 1,275 Vcore 50%Vdrop
(Temps - H100, 31 Idle, 67 / 68 Max core 30minutes @ OCCT / 6 Hours at Prime)
 
But hey im lucky and have a VERY Good CPU.
My ambient temps are around 24 to 30 here in Caracas.

Also, copy the BSOD code, so we can find the exact error you're getting, but it seems your cpu needs more power to get to those frequencies, your using both 8pins?

Lets hope you can find a stable and optimized OC! 

CPU Vcore [1400mv] is way too high, therefore you are getting high temperatures. Like Xtremed you gotta play with the vcore. You eleet to adjust in windows and just prime it on each change. Or intel Burntest would work great too.

Unless you got the worse proc sent out by intel : / which would have to be the case as previous people have mentioned your voltages are through the roof. 1.235 vcore is about all most need to clock at 44x multiplier.. some less, some more.
 
Just from what I know from your posts on this forum and guessing to some degree.. I kinda think you been ramping up your vcore and VCCIO cause of x124 and x9c BSODs, imo.. this is my opinion for sure, your memory may be stable at stock but it can't handle the beating its gets in the stress tests at those speeds.

Yes you should try rising up your Dimm Voltages, maybe to 1.6 / 1.65

I ran intel burn test with multiplier 43
Vcore at 1.275
vccsa and vsa at 1150mv.
Everything else left it at what i originally posted.(before increasing anything)
It passed.

But when i run prime95 blend, 2 hours in it bsod.

Wont setting it to dimm 1.65v damage the memory controller?

So im not sure it passes ibt with 15 high passes on 1.275 vcore but bsods at prime 95.

Should i increase the memory frequency and loosen the ti,ings or what do yall recommend?

No, 1,65 its the Max Intel Spec for Dimm, also some memories uses that Voltage, you can attach a screenshot from CPU-Z in the SPD tab! to see what its the XMP voltage for your memories!
 
But just try raising them to 1,6 at least if you're worried about that.
OCCT its a good tool, you can get a BSOD really fast :)

Just bsod.
Ran ibt on high.
@ vcore 1275
Cpu multiplier x44
Changed vccsa and vsa to auto.
Changed dimm to 1.6v

But ibt bsod instantaneously.

There are any number of routes you could take, 1.65 won't be any worse then what your doin with your VCCIO.. in fact its intel maxium which is still within spec though it may degrade sooner, but "sooner" is a relative term. Also, you could just go back to 1333 and see if its more stable.. all 1866 is overclocked 1333 to begin with. Or.. those timings do seem kinda tight for 1866 :p
 
All together its kinda plane you need to be looking elsewhere besides ramping voltages up on the proc, and its good that you are.
 
And you know, I like to give my opinion :p but depending on things I kinda think long burnins with prime 95 are kinda bragging rights.. full loads like that are very uncommon. If your gaming you never gonna use all cores like that or the bandwidth.

1866 with those timings and volt is what corsair said when i bought them.
I just increased vcore 1.3 and set vccsa and vsa back to 1150mv. @ x44 multiplier
Still bsod on IBT.
So right now im completely lost, should i set vcssa and vsa back to auto and increase dim volt to 1.65? change timings on memory?
 
Sorry about this, but totally lost as of right now.

Yeah, just like Nightlite said, never a game would ask for that amount of power, just like Prime, but hey, i had a friend that his CPU passed Prime95, OCCT, IBT and in BF3 he got BSOD... 
 
Uhm, you should try setting the memories at a lower timming just for testing, what BSOD are you getting? please paste here the code.
 
Put the VCCIO at 1.1, and try again, if this continues, it seems you have a bad CPU for OC just like Nightlite said, its a C2?

First off setting things to Auto with evga bios is pointless after they have been at a fixed voltage. Reset cmos each time, only way to be sure.
 
imo, let ram stay at auto 1333 setting for a bit and play around and see how it OCs.
 
Edit:  and I guess I add this little tidbit as well, Windows power schemes are deeply intergrated into C states and if not changed from balanced can do some odd things.. just sayin.

I don't have that issue, i tested my OC playing with VCCIO and VCCSA fixing the value @ 1,250, and then after some test, i put them in auto and the voltages went down. 

Yeah its a c2 stepping.
alright ill set memory to auto.
do i leave dim volt on auto as well?
Ill set vccsa to 1.1 and set vsa to auto right?
what should i set the vcore and multiplier at?

the bsod goes by too quick, but it says something like the proccesor missed a clock at the given time interval or something like that.
 
I will be doing some light gaming but mostly video editing and maya.

Blue screen view is a nice lightweigt reader, so long as the memory dump was made.
 
for 44x 1.25 vcore is a nice starting point, if it works start backing down. honestly nothing else should have to be adjusted for that clock.

First of all what are you using for testing?

Im going to tell you what i do for testing my OC:

First: OCCT http://goo.gl/0uFHl: CPU OCCT for 15 minutes, automatic, 64 Bits, Large Data Set.

Second: Heaven Benchmark 3.0, or 3dMark11: just a pass of the benchmark.

Third: Prime95: Select Blend, then Custom, memory to use increase it to the half of your Ram, just like 8gb or something like that, Time to run each FTT 3 minutes, (Quicker), just leave it at least 30 minutes.
 
At this moment if you don't have any BSOD you have an stable OC,  if you want to go further try IBT, and prime a longer time.

Also you can set windows to not restart after a system failure, so you can copy the full BSOD Code.

Click on properties on your  Computer at Start Menu / then advanced System Settings
 
In advanced tab go to Settings in startup and recovery, and then uncheck the automatically restart checkbox.

So set everything to auto (VSA/VCCSA), including dimm volt? Or leave it at 1.65?
and setting cpu multiplier to x44, and vcore to 1.25.
 
I use prime 95 blend for like 9 hours and ibt

Loosen the memory timings. Don't care what Corsair said they would run at. Just play with the timings. Loosen them up.

With these settings, i get bluescreen 3 mins into IBT.
this is what i got for the code of the blue screen:
 
A clock interrupt was not received on a secondary processor within the allocated time interval.
......
Technical information:
***STOP: 0x00000101 (0x00000000000000011, 0x0000000000000000, 0xFFFFF8800A717180, 0X0000000000000006)
 
Then after trying to log back in a get an instant bluescreen right loggin into the user of windows with this:
MACHINE_CHECK_EXCEPTION

Oh yeah
 
Core Ratio Limit Control [Auto] 
 
This shouldn't be Auto. Make it all to 44 like your overclocked it. Or the turbo will push it too high and into a BSOD.

Oh yeah

Core Ratio Limit Control [Auto]

Changed it to Manual
everything was 44.
& bluescreened when running IBT again:
***STOP: 0x00000101 (0x00000000000000011, 0x0000000000000000, 0xFFFFF8800A717180, 0X0000000000000008)
 

101 error... more vcore ;)

Try 1285 and work your way down from there.

I would suggest start from 1300 using 75% Vdrop, leave your Dimms @ 1,65, and test.
 
If you don't get any trouble try raising the memory frequency, to the speed intended by the memory (1866), and leave the dimm voltage @ 1,65
 
Next, start lowering the Dimm Voltage, until you find the lowest value posible without issues.

Then start lowering down the CPU Vcore, using intervals of 10, or 5, to find your lowest voltage needed.

If you follow the method i described you could get a BSOD really fast, also it seems your CPU needs high voltages to work at high frequencies, so don't worry and keep trying! 

feck man.. use those voltage points on the board, I need some proof at this point. Is 1.4 really 1.4?

Hey I was wondering if you would try something for me Infamous? I been reading some good things about using the Bclk and SBe so.. I been playing with it. Pretty much seems I can get the same clocks I can with multiplier but with less voltage, and it kinda seems that I benchmark better as well.
 
atm I am running 4.375ghz @ 1.22v with some real low temps, which is pretty close to what you were looking for.
-Bclk 1.25
-Multi 35
-Vcore 1.22, though you might have to go higher :p
-vdroop 50%
-ocp 125%
-rest auto volts
-memory- I run DDR1600, cause I want to! anyways at auto setting that would be DDR1666 with that Bclk.
 
4.6 takes a bit more tweaking and 4.8 is more then I'm willing to give in voltage.

i dont have a volt meter. :/
 
I tried cpu mult x44 @ 1.3v, IBT passed on standard 10 passes, Blue screened on high.
Then i increased the dimm volt to 1.65, tried again, and bluescreened on standard.

ill try, but i read tht messing with the blck wont let you overclock period.
As for xtremed, ima try download occt and heaven and try your method of stressing. But if it cant pass on IBT on high for 15 passes then its not stable at all.
 
edit:
computer just completely froze while running IBT again right now. no bluescreen. Cpu mult x44 @ 1.3v with 1.65 dimm voltage. I had to hold down the power button because pushing the power button once wouldnt turn off. All other setttings are the same as i previously posted in the most recent template.
