I ran it at small FFTs for 11.5 hours and everything seem good. However I did see a peak temp of 100c on the 2nd core
I should note that it is Ivy at 4.7 and a Vcore of 1.368. any thing less then this is not making past 2 hours

It's almost always more.

So heres your 2 options:
Offset Mode: Your CPU will use VERY LITTLE voltage and speed when idling, ANYTIME you idle. (Even browsing can be considered idling.)
Enhanced Halt State (C1E): Enabled
CPU C3 State Support: Disabled
CPU C6 State Support: Disabled
Package C State Support: Disabled
Fixed Mode: Your CPU will run full voltage and speed all the time, even when idling.
Enhanced Halt State (C1E): Enabled
CPU C3 State Support: Enabled
CPU C6 State Support: Enabled
Package C State Support: Auto

I'm new. Which is best for me to use?

Hi guys,
I'm at the 42 page of this thread but want to post my results from today, so I get some input how/if to proceed.
these are my current settings and to me it seems I hit the jackpot with this chip. never crashed yet (idle or load) and I think I'm keeping it at quite low V. I would try hitting 4,5 if I can get it at/under 1,35Vcore cos for games I think there is no point going up. I want to keep it as cool as possible in idle so I have a silent machine (noctua rules :-)) while browsing,... which is 90% of time. I don't do any folding/benching/video editing,..just games and common stuff.

cpu: 4200mhz
cpu core voltage: 1,216 - 1,224 (sometimes very rarely drops to 1,208 in cpu-z under load)
offset voltage: -0.070v
cpu load-line calibration: 4

1. I'm worried about my idle V. is 0,912 maybe to low? my stock was 0,944. I run prime95 blend (default) for about 2 hours without problems. max temp was under 60C (room 23-24C).
2. is a version of prime I'm using (26.6 build3) good one, or should I use later one 27.7? As I understand v26.6 is x64?
3. should I bother with any other stability tests (LinX (AVX) v0.6.4, hyperPi, OCCT, wPrime, IntelBurnTest v2.53) or just stick to prime95? (I will use these benches when I start testing for overall stability (cpu, GPU, ram): memtest, 3d mark(s), crysis1, crysis2, metro 2033, call of prypiat, heaven, evga oc scanner).
4. which test to pick inside prime cos I was using default blend?
5. I don't get the connection between vcore and VID and should I even be bothered with VID or just look at vcore? I meen, is VID something that CPU is calculating that should be used for specific clock, or this value is what is actualy used? I think it's the latter one as I understand.
6. I'm still not sure about c3, c6, package c state and no-execute mem protection. what exacly do they do and should I bother? btw I heard about connection between c states and performance of SSD but not sure should it be enable of disable for better perf. c1e and speedstep are for different speeds so are other c states only to enable stand-by (that I don't use) or...?
7. should I touch PCH voltage, cpu pll voltage (I have seen someone using 1.750), vtt voltage (seen 1.057), vccsa voltage or just leave them alone on auto?

thanks.

Neither one is best. Choose based on your electric bill. First one, less power. Second, more power.

Some find the second to provide a more stable overclock. But nothing major decisive.

I prefer Offset myself since it lowers temps and power usage, especially since I usually leave my computer on most of the time.

Bah...
I left my PC for Prime95 In-place Large FFT (Maximum heat, power consumption etc..)(the middle option) last night.

I was greeted with "Prime95 has stopped working" message when I returned to PC this morning. Sad thing is, previously, this PC passed 20 passes of LinX and 10 hours of Prime95 small FFT test.

Personally, I've only seen BSOD, freeze and/or rounding errors when Prime95 when it comes to overclock instability.
Anyway, I'm sure "Prime95 has stopped working" message is a sign of instability.

Ok.

I'm using AsRock Fatality Z77 Professional.
3770K @ 4.5 with 4 x G.SKILL ARES 2133MHz (16GB) (1.65V)

Offset mode = +0.050V
Load-line calibration = Auto (Level 5 which is the lowest/mildest)
All power management options are at default (enabled) (C1E, C3/C6 etc)
I have not touched PLL nor VCCSA etc. (Pretty much all these are at default).
Under Prime95 small FFT load, CPU-Z reports 1.200V. And under Prime95 large FFT load CPU-Z reports 1.208V

What should I touch to get prime95 stability ?

Random: when overclocking..in Prime 95 (load), I notice that one of my cores is sometimes actually 10C cooler...than the others...anyone else get this? i think it's pretty normal...just checking.

This is normal to have some fluctuation but at full speed they should be closer then 10c difference it could be heatsink ustment is needed but I don't wanna stress you over nothing.
