Sorry, I pop in and out of this thread very spontaneously and keeping track of 400 pages is nigh impossible. Still I randomly chose this page so hoorah? Lol anyhow I'm not sure if you ask out of disappointment or enthusiasm but my VIN is 2.1, kept getting instability with a worker crashing at 2.0 and didn't realize it was my FIVR till after adding quite a bit of voltage to my core and cache. I'm sure I'll be able to tweak it down a few tenths but for now 2.1 is def enough and 2.0 is def not.

To reiterate 4.7/4.7 at 1.43core 1.45ring 2.1vrin and .3 to sa/ia/io cause I'm running my 1866 at 2200 with tight timings. (I know I need faster ram)

I actually consider this chip to be a bit better than average, yet u would think it was garbage if you take to heart all the impulse "I'm stable" posts and the degree of scrutiny some people apply (or rather don't) to what they believe is stable.

FTR I have had this PC a few months now and have YET to play a game due to hours upon hours upon hours seeking a 24 hr run of prime95 blend. I was misled on what people were labeling "average vcore for xxxx speed" and when I would surpass that by a great deal, I would look elsewhere and never got stable before I realized it needed even more.

I am now stable in IBT on max. In hyper PI (great for ram). And In prime for 23 hours and change (I'm done! Lol) I have had so many 10-14 hour runs where it finally blue screened I want to shoot myself. My friends are all max level and some in ffxiv (which I built this PC for) and I have yet to start. Now THAT is two things, OCD is one of them.. Stable is the other tongue.gif

There was a fair amount of initial degredation which didn't help either. Still I always knew power and temp were never the issue. Took me a long time to come to the conclusions I have but I'm beyond confident they're very very sound.

FWIW I can pass IBT and hyper PI at nearly the same voltage at x48 but so far at 1.525v it was still failing prime blend. I know I wanted a 24/7 OC and I knew that I wasn't comfy running what could have amounted to 1.55 24/7 so as much as I wanted 4800mhz I had to call it.

So for those calling their 4800 @ 1.25 overclocks stable cause u can play games and take a SS or pass Aida or such, let me know when u pass prime for 24hr. Then I'll agree tongue.gif

I've been working on 4.7 recently and bsods all the way up frown.gif
I thought that 9c is vcore related and it is but....
Now I figured it out that 9c ->vrin, 101->vcore, 124->vring
Maybe I'm wrong but I don't think so

Username:SgtRotty
CPU Model:4770k
Core Multiplier:45
CPU VID: 1.255
Vcore: 1.272
Input Voltage:1.856
Uncore Multiplier:39
Uncore Voltage: default override
Cooling Solution:h100 push/pull (68c highest core)
Stability Test: bf3 only,tons of servers 64 players(no prime95,aida, etc)
Batch number: L312B534
Ram Speed: 2400 GSkillz 10,12,12,31,1T

Just posting my specs and results. I think its critical to have cpu input .600 above vcore for proper volts and smoothness. Ive been using these settings for couple weeks now. I waited a little bit before posting to ensure its stable.
I appreciate all the info in the guide, ive read it all, i keep referring back to it. Thx to all!

Edit: also using SA.150, IOD.030 IOA.030. Havnt messed around with the ring much. Sounds like it doesnt help much

For me 124 error is definitely vcore. Btw min vcore stress testing for 4.7Ghz, tested with folding, with 1.25v crashed after 5 hours. Still to test uncore and ram. If i want to move to x48 i have to delid, i dont like to see this 80C on the first core mad.gif

Still having issues with mine just shutting down completely. It will boot saying overclock settings failed. Happened this morning after having my pc on for 5 minutes where last night I played about 3 hours of BF3 with no issues.

But what's the point if on you only use it to game on? Seem's a bit retarded & obsessive being able to do a 24hr run with Prime just to game on.

4,6 GHz with 1600 RAM or 4,5 With 2133 RAM? Ik i asked this already but pls New mentions biggrin.gif

Oh my goodness, no you didn't...

But seriously, this guy knows what's up.

If you ask me, your chip is top of the line. Fact alone that you can push such voltages and remain p95 (prime 2.81?) stable is amazing. I had to drop 300MHz to be allround stable including p95 2.81 and latest Linx with linpack 11.1.

My chip just cant sustain high voltages, the more i set the more inaccurate it gets. Tried finding different trade offs between mem speed, uncore and what not, and it all boiled down to voltages. I once managed to get 45x through 10 hours of prime, but it was heavily castrated running 38x uncore with 1600 mem. It was easily outperformed by 44 with 43 uncore and 2133 in every test, except cinebench. I settled on that, but would have wanted more.

It could be my board, i have VRM's only on 1 side and it may cause unstable power delivery. What board are you using?
