I realized that, have removed them & will be adding new ones shortly. I deleted my original post as Josh said the images were too small so I will put my results, thoughts & screenshots below & see what guys think. I was surprised, but I am not sure if I understand them correctly?

Great Video & written review as always. I watched & read them both twice. Whenever i have overclocked before on Intel (Only moved from the reds about six months ago) I have always let Mobo adjust the voltages on auto due to not being confident enough for manual adjustments. I decided to the same again this time just so I could get an idea of how the voltages went up or down during the OCCT tests. For this reason I left one minute idle time at the start of the tests and the five minute after. That apart I followed Tom's settings and ran it for thirty mins. My rig componemts are Asrock X79 extreme11, I7 3930K, GTX590's x 2 in quad SLI, Corsair Vengeance 1600Mhz 32gb (8x4Gb), Kingston Hyper X 120Gb SSD's x2 (Raid0), CPU & GPU's are custom W/Cooled in Caselabs STH10 on two separate loops. Have not put PSU, HDD & other components as I did not think they are relevent. Right, I overclocked my CPU using Asrocks AXTU app. To 4.2Ghz as a starting point (Normally I run it @ 4.4Ghz.) by changing the multiplier to 44 and everything else on auto apart from the C states of which I disabled all of them. With the volts on "Auto" which is 1.245 I started OCCT, for the first minute voltages varied from 1.239 to 1.256. After the first minute the voltage dropped to between 1.18 & 1.19 all the way through the test this was the only voltage changes. After 25 mins the 5 min "Idle time" kicks in, as soon as this happened the voltage went back up to between 1.239 & 1.265. I am not sure what to make of these results but, if my understanding is correct it vindicates what the Video & written review are saying about the preset voltage on my motherboard is set too high???? I have added some screenshots and would like to hear what some of you expert experienced guys think. Thanks for reading & I look forward to reading what you guys have to say.

Nice basic guide Tom...well, I say basic but it's likely all most people will ever need unless they want to start getting crazy lol.

I actually watched this guide in full, then overclocked using Tom's methods on my ASUS P8Z68-V Pro with 2500k and the settings translate across nicely from the Gigabyte board Tom used.

Interestingly, this is NOT the way I usually overclock, I'm an offsetter myself, plus I preserve all the power states etc. so my clock speeds are dynamic. With Tom's method I managed the exact same level of overclock & stabiliy pretty easily. I had the same CPU vCore reported under OCCT Linkpack load, though of course at idle my overclock settles down to 1600mhz on the CPU with around 1v on the CPU vCore. The joy of power states lol.

I could push a fair bit further on my overclock as I have excellent water cooling. However, I did NOT win the silicon lottery by a long margin with my CPU, sadly my Core #3 is pretty damn weak compared to the others, so I need a higher vCore than I'd like for that weaker core. Still, 4.6ghz for a 24/7 OC isn't to be sniffed at, and it gives me a healthy boost in many CPU demanding tasks.

It used to be that the first thing you disabled when overclocking on socket 775 was the power save states. With my Q6600 @ 3.6 I had to do this to get any stability. With Sandy Bridge I noticed that keeping all the power stuff enabled hasn't impacted my peek stable clocks at all, which is pretty cool. Erm, quite literally :)

Oh, the undervolt at stock to get your base line is a great way to start. I thought I was the only person doing that! People used to think I was daft, but my OC's worked & lasted better than theirs *smug* As for the "Auto" overclockers out there, I think you REALLY showed how badly motherboards get the real voltage requirements wrong in that mode - quite shockingly so.

Really useful guide that has directly given people additional FREE performance, which can't be bad! :)

Scoob.
 
I have a problem on my secondary rig, OCCT only allow me to "use" 8.3GB RAM (I have 16GB) If i try to use more it just says "Finished" and doesn´t start and when i´m running it at 8.3GB the OS complains that it´s to title free memory (still have 5GB+ och free memory!) and sometimes I get "Out of memory" and if i don´t shut down OCCT the system just freezes (not even blue screen)
The other spec:s are Gigabyte GA-P55-USB3
I5 750 @ stock (was running oc @ 3.2GHz but loaded optimized defaults due to this problem)
16 GB 1600MHz corsair vengeance 9-9-9-24 4x4GB (now at 1333 due to "opt defaults")
I know it´s not Z77 but still.
Guess that´s the parts that matter, does anyone have any idea on what it might be?

Could it be that i need to increase the V to the memory controller on the CPU since I´m running four dims?

Edit: In prime95 one of the cores will at random (or so it seems) fail to initialize FFT code

Edit 2: Think i found the problem, my audio "driver/program" when i quit it I could use "90%" of RAM whiteout any "Blue screen" stuff, very strange.

Good evening to all

i watched the video completly so im starting with 1.245v @stock
and make the first step to 1.200 but is 30 min occt really enough to go then again further down ? if 1.200v is stable maybe to 1.170 or so or is it better to let occt running a lot more time wise?

I7-2600K @stock on auto 1.245v cooled with an H80i
G1 Killer Sniper 3 Z77 Bios F8J( Newest available)
8 GB Corsair Dominator Platinum 1600 MHZ CL9 no XMP
Gigabyte Gtx 670 OC
Samsung Pro 128 GB

you can let it go for a longer stabilty trial, but in the sake of time, 30min is
plenty. once you have established the lowest voltage without crashing, BSOD
or windows loading failure, revert to last 30min stability voltage and that would
be your undervolt for stock. then you can do a 24hr stability test to verify
that is the lowest and safest voltage to use. even after 9months you might find
that your temps are higher or your get random crashes. now you know what to
do. decrease the multiplier, increase the voltage or maintanence the cooling
solution.

the idea is for you to find that best case scenario in voltage and multiplier
that offers stability. and instead of big swing numbers, trying the stepped
method gets you familiar to the BIOS, how to react to errors, what to look
for in an overclock. look at how the CPU generates heat with each voltage
increase. once you find you are in the 40+ multiplier, the temperatures start
to increase in larger amounts to the voltage increased. from that you start
to understand the thermal capabilities of how overclocking a CPU holds.
if you find the temps are higher than you like, you have options. fine tune
your overclock, increase the cooling solution, reduce to overclock to a temp
suitable for your environment.

One thing I've found that can catch you out sometimes with such testing is partial load. I.e. you run OCCT all day stressing all four cores and all is well. You then run an older game that's not optimised for mulitple cores - thus stressing ONE core - and you get instabilities. I've had this a couple of times, where EVERY stress test would pass (on four cores) but a certain game would eventually fail. I did not need to up vCore, but a 1 notch increase in LLC did help. I think this is a fairly rare issue, but my friend had the same problem in the same game with his 2600k OC...

hi, i hav got to 4.5ghz on my 3770k at 1.130v in the bios but in cpu-z the voltage is 1.160 on load, is this normal?

set vcore load line calibration to turbo/extreme

Ty for reply so 30 min are ok?
I want to overclock.
Then say 1.170v is stable i can put 1.200v for 4.0 ghz and so on..... then say i will try 1.200v for 4.2 ghz which is 30min stable and then make the 24/7 stability test is this a good way? http://forum.overclock3d.net/editpost.php?do=editpost&p=620480

hi, i hav it on extreme?

thanks, went in to bios and changed llc from extreme to ultra high and upped my voltage to 1.140 and now in cpuz it goes up to 1.144 on load :)

Edit:
i hav just stopped occt after 8 min whn i noticed that my cpu vcore dropped to 0.32v, vin1 to 0.01v and +3.3v to 0.03v is this a fault with occt or my system?
i hav a 1200i psu..

Try a CMOS reset, pop the battery or short the pins, depending on the method for your motherboard. It will reset EVERYTHING so you'll have to spend a little time reconfiguring stuff like drives, ram etc. possibly.

My guess is that your OC is unstable - but you knew that lol - and the PC cannot even get into the BIOS. Remember, when you are sat in your BIOS your CPU is loaded (a little) and will run at its max clock speed. Sat in the BIOS for extended periods I could see my temps go up, not to gaming levels, but not far off.

Might be something else, but I don't know exactly what you've changed.

Best of luck.

Scoob,

Thank you for your answer. I'll try popping out the battery; hope it helps. Have done that with a few issues before - all worked out perfectly.

Yeah, it's because I raised to multiplier to 48 with a vcore of 1.290. My chip wasn't able to run that. :(

Again, thank you. Have a nice Sunday!

Hello,
I'm having some boot issues after I raiser my multiplier to 48, I think.
Does anybody know a fix for this?

once you recover from the "boot loop" error. you need to re-watch the video.

you are taking way to big of swings to this process. small incrimental steps
are necessary for proper overclocking.

also, if issues do arise, a hardware spec of build would help a whole lot, too..

I was at 4.6, and was going for 4.7 but pressed the plus button twice instead of once.

Wanted to edit my first post and put my specs, but the post was waiting to get accepted by the admin(s).

Specs:

2500K
Corsair H80
Corsair AX850
EVGA GTX 680 SC
Corsair Vengeance 16GB @ 1600MHz
Gigabyte GA-Z68X-UD3H-B3, rev. 1.3, BIOS F11

Guys,

I was trying a overclock of 4.5GHz, vcore set to 1.290. Temps and vcore were:

But after ~8 min. my system went:
