What is all this bickering about VID about?

VID is just a table of voltage numbers set for each multiplier.

Intel makes these tables for each individual batch of chips.

They only test voltages up to the stock multiplier.
If they tested more then they would be wasting money on R&D costs because the chip isn't advertised to be stable at anything other than stock.
The stock multiplier is usually chosen because it works well with the stock Intel cooler that most PCs come with.
Imagine bulk orders of 1000 PCs for a corporation.

It just so happens that Intel chips can be vastly overclocked by using an aftermarket cooler.

Back to VID, anything past stock multiplier isn't tested. The numbers just increase linear until they reach the maximum allowed VID. (In the case of Ivy/Sandy the VID tables max out at 1.52v).

The VID is useless by itself in setting a voltage for multiplier past stock (as in auto-voltage mode).
The VID can be used tell how good your chip is. The lower the VID at stock, the better your chip is.
The VID can also be used to tell you what your offset should be for a specific wanted voltage.

For instance, if your VID at 4GHz is 1.4v then you know if you were stable at 1.3v on Fixed mode that you should set an Offset of -.1v for 4GHz multiplier.

...and that's that.

Stop the arguing.

Feels like I am hitting a wall with my i7 2600K on my Z77 Pro4 board... Before I was running it on auto OC mode @4.6ghz and it was stable, but the VCore was a bit too high (around 1.450V). So I wanted to get it to work on manual settings with less VCore.

As soon as I try to up the multiplier above 45 it all get messy. I get blue screens (win8.1 doesnt show BCOD codes...), rounding errors in Prime95 or it doesnt even boot. Changing VCore, Turbo Boost or CPU PLL doesnt do anything except raising the VCore on load above 1.450V again and it is not even stable at this anymore. I also saw some weird multiplier spikes, it went from x45 to x34 sometimes, normal on prime95?

Any ideas what should I do? I think I got lost on this guide, because my board doesnt support a fixed VCore... its not possible to set it in BIOS. Here are my screens:

first of all, lock your multiplyer to a set value. don't leave it at auto.

and what was your load temperature before with the auto overclock. sounds like you might be overheating.

since you had 1.45vcore at 4.5ghz, i would start there. set the offset voltage so that it equates to 1.45vcore during load, check CPU-z. make sure the temperature is reasonable like no more than 80c for your chip during load. and from there on, you can try upping the multiplyer up by 1, and up the vcore offset a notch or two from there until it stablizes in prime95. make sure the temperature is table during the whole time otherwise you have an overheating issue.

edit: there is your issue, your CPUz shows 1.336. try upping the load line calibration, or up the vcore offset so the load voltage is roughly 1.45 or somewhere along that line. you need to find your baseline first. i am guessing it's somewhere along 1.4~1.45, since that was stable for you in auto.

Your BIOS settings look good, although you could change the offset to a positive +.005, and we dont have a shot of your advanced CPU settings (i.e the C-States). To get it stable, leave everything like it is, and increase the "additional turbo voltage" until it stabilizes. 1.45 is a good chunk of voltage, particularly for a board with 4+2 power, which could be the source of the throttling if it is not the core temps, make sure you keep those VRMs cool. What type of temp readings are you getting? What CPU cooler are you using?

Ok, so I've managed to get there, but the temps are slightly higher (2nd core seems to output much more heat compared to others, but I guess that's considered normal).

Anyways here are some screenshots:



BIOS
Warning: Spoiler! (Click to show)


Is there any way to get those temps down a little bit? Seems like anything bellow +0.039V is unstable.

Also any idea why does my CPU-Z keeps showing up the 'Bus Speed' at 99.98 Mhz? Afaik I've disabled the 'Spread Spectrum'.

Thanks!

Its set to 45, what do you mean?

This is from Auto Turbo @4.6. The Offset is set to +0.020V, Turbo Offset is set to Auto, LLC to 0%. As we see there were some spikes to 80°C.

I am using a Thermaltake Macho HR02. It looks kinda hot for this kind of cooler imo. I dont know how to make it more agressiv, its set to a target temperature of 65°C on bios. Maybe set it to 50°C so it kicks in earlier?

About VCore of 1.45V: I read alot of times going higher then 1.35V is not healthy at all for the components. What do you think? I was running it now for almost 3/4 a year on 4.6GHz on auto turbo. And my intention of manually overlocking was to get the VCore down to 1.3V again, going higher than 4.6Ghz isnt possible anyway with this chip and board I guess.

you can try to lower CPU PLL voltage to 1.7 or 1.6, it might lower your temp by a degree or so. but there's not much you can do if anything below +.039 crashes. your temp looks fine if those are your prime95 temps. in everyday use, they'll never go as high as prime. enjoy your new OC smile.gif

your auto overclock setting was 1.45vcore, your manual OC setting is 1.336vcore, so somewhere in between those two numbers is a sweet spot where your comp should be stable but below the 1.45vcore. you can eighter raise the offset voltage, or raise the turbo voltage slowly to stablize the comp, or you can also try raising the load line calibration (LLC) to a higher setting, i am guessing for your mobo 75% or 100%. the worst case scenario, your comp might need exactly 1.45volt for 4.6ghz, but that's probably not the case.

Need opinions? Improvements? Read a lot on this guide as well as the responses. Much appreciated.

Seems like you still have quite a bit of headroom left if that's your maximum temp in prime95. Have you tried 4.6ghz?

I see that you changed c3 ,6 state to disable. Which is a good precaution. I don't see anything that'll warrant a red flag. I would try 4.6 or 4.7 next and watch the temp closely.
