Ah, thanks for clearing that up!
Since my last post, I have been trying to further stabilize my 4.5GHZ. I figured it would be best to accomplish this first with minimal VCore before trying to break the 4.5GHZ Barrier.

Right now i am running 4.5GHZ with -0.06 Offset, 0.004 Turbo Boost @1.256v and 61 degrees.
This is giving me a stable 30 minute P95 blend.

Am i going in the right direction with this??

Ok,
I have a 2550K 3.4GHz and wanted to overclock it.
I have never overclocked before so I followed this guide to the letter:

Set the multiplier to 33, offset to 0.005v and turbo to 0.004v and ran prime95,
it worked fine, so i upped it to 34 and ran again - was all good, got to about 37 and had to up the turbo voltage a few notches but I managed to get it stable for at least 10 mins so i upped it to 38 and literally couldn't get it stable no matter how high I upped the turbo voltage. The last I tried before I gave up was +0.141v and it still kept failing Prime, don't know if that's considered high.

vcore was kinda fluctuating around 1.328 but it had been for the past couple of hours and all that upping the turbo voltage didn't seem to push the vcore any higher.

I did have a few BSODs but it went away so fast that I have no idea what code it was.

Even when I reset everything back to the saved Starting Profile of 33 multiplier and 0.005v offset, and 0.004 turbo, it was no longer stable at that.
Confused.
Because it was before so why not now?

Anyway, I am clearly a noob but I would like some help if anyone's got the patience.

Slight problem I have been having. If I set the cpu to 4.6ghz it stays for until I let off the power(IBT), and then put it back on again. Then it won't clock above 3.3ghz. Any clues?

You might want to check if you missed to turn on or off a setting as specified in the guide. Also, you might have overlooked your cpu temperature?

I had RealTemps running the whole time, and it never pushed past 60 degrees C, and I don't think I missed anything, I set everything to what the guide said to, and at first it was working, unless my chip just simply will not go higher than 3.7Ghz, which seems unlikely to me, but I don't know.

Yea, that sounds about right. See if it's stable for 12+ hours. If not, just increase turbo boost one notch until your build is stable.

Going to get an Extreme4 soon. This thread will come in handy.

I found OCing my 2500K weird in that it was the first time I really had ever OCed an Intel chip by simply pumping up the multiplier (I did that a long time ago with an awesome mobile Barton AMD). But that's the name of the game with these chips and chipsets (previously, most OCing of Intel chips occurred by bumping up the FSB, as chips were not unlocked). Anyway, so with my z68 system (see sig), I started off with everything set to default in the bios and simply started bumping up the multiplier. Did not do anything else (except for turning off the auto setting for the multiplier). And I was able to get up to a mult of 45, and thus a speed of 4.5GHz. Now a number of folks told me I was nuts for not setting my vcore at a single voltage or using the offset setting, and the latter is ultimately what I did (along with some other tweaks). Note that my temps were not all that outrageous when I simply pumped up the multiplier. So maybe try that. It might at least give you a sense of what your chip can do. As I recall, the vcore will automatically go up with your multiplier. Again, my temps did not go up excessively, and to this day I have never had any of my core temps much over 70C while running prime95 or OCCT.

Maybe this will help get your speed up, see what that chip can do. Good luck.

Hi
Great lesson on OC but im stuck at the udervolting part. I cant find the CPU Multiplier I have spent the last hour looking?? Any Help would be great.

^^It's the CPU ratio. Set it to all core then it will allow you to change the numbers.
