Sorry, I guess it's a bit much all at once.

It seems (and I'm not trying to be obtuse or skirt reading the OP here, just trying to understand the process) that in addition to raising the clock speed, I'm also supposed to set an initial voltage other than "AUTO." What is a good voltage to begin with? In the OP, the hypothetical starting voltage was 1.0V...

That depends on the CPU. If you use Offset-style voltage (and you should) with an offset of +0.00, then the default core voltage will be exactly as the CPU would request at 100% stock settings. And for Ivy Bridge CPUs like yours, that's usually around 1.05V. In fact, you should not need to raise that voltage at all to reach 4.2 GHz. But if you do, then tweaking the offset would add more voltage to the base amount.

quote:

When running my system with stock BIOS settings, I've been idling around 1.05~1.08V while running Prime 95 has pushed that to 1.1959V with temps ranging from 39~42C (my coolest core) to 54~57C (my hottest core). Would it be smart to set the Vcore to 1.2V, up the clock to 4.2, and then test Prime95 again... or should I be going even less on the Vcore?

That's a pretty darn reasonable actual Vcore, so I'd just stop worrying about it for now if the clocks you have are all you want. It sounds like your board has a lot of Vdroop (difference between Vcore and VID) is all. If you wanted to push higher, you'd probably need at least a little load-line calibration (Vdroop control, in the MSI BIOS). But as-is, it's fine.

Also, "too hot" is roughly 72C under Prime95 or similar real-world 100% loads.

Is there any way to do this on an Asus P8Z77-V?

The UEFI seems to interpret 0.00 as "auto, go hog wild"

I'm quite happy with this overclock, but I'm a bit worried about the temps. Is it dangerous to run it like this?

That Vcore is way too high for a long-term safe overclock. That voltage would burn out Sandy Bridge prematurely, and its transistors are almost double the size. You seem to have good cooling if you're only getting 82 C (which is too high, and doubly dangerous with your voltage) at that high a Vcore, so dial the volts back to 1.3 and take what clock speed you can get.

Also, you really shouldn't have your BCLK anywhere but 100.0 MHz.

KillHour

This one looks stable. Would have preferred at least 4.6, but :effort:.




Edit:

Is there a reason you shouldn't up the bclk? I thought it was "Up the multiplier at your desired max voltage until you can't go any higher, then use the bclk to get every last Hz out of it."

With SNB/IVB, the whole platform is incredibly sensitive to the bclk. I don't remember the exact details, but things like the PCIe slots are running off of it, not just the CPU. So it's best to just not gently caress with it and deal with the small difference in overclock.

Using Straps you can do some good stuff with both the Unlocked and non Unlocked processors, but +- 3 to 7 Mhz can net you some good gains without that much of a stability problem depending on the motherboard. You just have to watch out about doing to much or you can run into I/O errors and such over time. I'd say though that 3mhz either way isn't going to hurt a thing though.

For some reason I have yet to prove on my side, a 125Mhz BCLKC strap is supposed to require less voltage than using the multiplier to reach the same OC, though I have yet to have much success with this method. It could be partly due to the fact that I refuse to run my ram below rated specs. :D

Buy an Intel Core i5-2500K CPU and an Asus P8P67 rev. 3.1 motherboard. Go into the BIOS/UEFI setup and set the CPU multiplier to 42. Exit and save changes. You have just overclocked your processor.

I browsed the OP, but didn't see an answer to my question. Do I need an aftermarket cooler to do this? This guy is currently only $20 and looks like it has great reviews. I'm just not sure I actually need it. Does the answer change if I'm doing it to a i5-3570k instead of a 2500k?

No, but if you don't have one, the CPU fan will ramp up to fairly annoying levels. If you don't want to go aftermarket, stick to 4 GHz or so.

That said, a Hyper 212+ is a great cooler for the price. Use one myself.

Ok, one more post from me (apologies for my annoyingness)...

Running a 3570K @ 4.2ghz and getting a Core Voltage in CPU-Z that jumps between 1.176 and 1.184V.
My temps in Real Temp seems to be hitting maximums of 51, 65, 61, and 59C.

Does all of this seem pretty safe and standard for this level of overclock? I'm flirting with going to 4.4 but will probably leave it here for the time being.

Temps seem a little high for that overclock, but totally fine. Just keep an eye on them and your voltage if you bump it up. I don't see any reason not to go on and try it at 44.

How reliable is the monitor on the ASUS AI Suite II thing? I OC'd my 3570k to 4.0 Ghz and under load it shows a vcore of about 1.238 volts and a temperature of 57*C, which I know are fine, but I want to make sure that is a good monitor that isn't lying to me when my cpu is actually burning up (it's my first time OC'ing a cpu and while I know a 4.0 Ghz OC should be cake, I'm just paranoid about catastrophically loving it up).

Looking a couple posts up, it looks that I might have set the voltage a little too high. Would I even need to change it for this small of an OC? I assume that would bring the temp down too right?

The most up-to-date version of HWiNFO64 is a very good monitor. The ASUS AI Suite may be accurate but it's a cumbersome pain in the rear end to use.

I used this, but it shows VID rather than Vcore... while HWiNFO64 was displaying my system at a VID of 1.27V, CPU-Z showed that my Core Voltage was 1.17V.

Per the OP, it seems that the Vcore number the the one to pay close attention to, unless I'm misunderstanding things.

It would either be the former, or that IVB just runs a bit hotter (though at that voltage I wouldn't think it would be that warm, but again it's not really anything to worry about). You can try cleaning and reseating it if you want to, but as long as you don't kick it much up over 72c (someone correct me if I'm wrong on this for IVB) on your hottest core, it's fine.

Your case, while goofy looking, seems to have ok airflow.

hwinfo64 shows both vcore and VID. Hell, it shows pretty much everything. Vcore is what you want to look at, though.

I think aisuite only shows the CPU package temp, which is somewhat lower than even the coolest core. Since you are most concerned with the warmest core, you need to be looking at something like hwinfo64 to get a baseline.

HWiNFO64 displays both. Vcore is listed under the Motherboard header towards the bottom.

Scroll down a bit, Vcore should be there. Earlier in the thread I posted regarding similar issues in trusting the temperatures. I found that the AISuite CPU temperature was inaccurate- I think that it is reading a sensor that is not on the CPU itself but near it, in the socket maybe. Stick to whatever lists the readings of the DTS (Digital Thermal Sensor) on each core for the most accurate reading.

My old mobo broke so I was in a rush and didn't really do much research buying a replacement.

I got the i5-3570K, Asus P8Z77-V LX & coolmaster 412S.

One warning for people using this mobo is that auto voltage sets the cpu voltage pretty high (> 1.38V). I was hitting 100C. I'm not really sure what I'm doing, but here is what I've done.

So I set most of the setting regarding voltage,current,etc to normal.
Offset @ +0.1, with a multiplier of 45 crashes.
Offset @ +0.15, with a multiplier of 45 works.
Offset @ +0.6 with a multiplier of 44 crashed.
Offset @ +0.7 with a multiplier of 44 seems to work.
I'm happy with 4.4Ghz, especially with the difference in temps.

My guess: you're using constant voltage (or disabled SpeedStep and C-states) and not using load-line calibration. That's just Vdroop, and it's entirely expected. Switch to Offset voltage and re-enabled EIST and C-states if they've been disabled to bring the idle back down to ~1.05V

I can't find anything about that by Googling. Do you have Catalyst 12.4 installed? Does that happen at stock clocks/voltages?

Even if your drivers are up to date, you might want to do a full reinstall of them. That's:

1) Uninstall drivers from add/remove programs
2) Reboot (do not skip this)
3) Run DriverSweeper
4) Reboot again
5) Install the drivers from a freshly-downloaded package
6) Reboot once more

Factory Factory posted:

Ai Tweaker -> Turbo Ratio: Manual, Ratio Synch Control Enabled, ratio limit 40x

4.5 GHz will probably not appreciably affect chip lifetime, since 4.5 GHz doesn't take a lot of voltage on Ivy Bridge. The chip may never make it on the Future Space Shuttle like old 386 chips, but it'll last at least as long as you'll ever find the system useful.

Except I used ratio limit of 45x. Is there anything else I need to change? I downloaded HWinfo64 and I see my core ratios jumping between 45x and 16x an awful lot. I don't know what I'm doing or if this is even working. :confused:

Preset overclock settings are fine if you don't want to do it manually, but may result in too-high voltages/temperatures or may not be stable, since chips vary quite a bit in what they need for a particular clock speed.

Make sure your CPU's temperatures stay reasonable, and run a stability test to make sure everything is stable. 45x is in the range where you can't assume that "auto" settings will be sufficient.

Voltage looks good at 1.25V and temperature settled in at the high 60s.

So, how about 4.6 GHz? :getin:





Hot drat look at that voltage! Look at that CPU temperature! :ohdear:

Despite seemingly being stable in linpack, there's now way in hell I'm leaving it at 4.6 GHz, so I've gone back down to 4.4 GHz and will stay there. I can't believe how easy that was. Keep in mind this is a mini-ITX motherboard.

gently caress it. 4.6 GHz is stable and doesn't send temps or voltages nearly as high when doing anything else that isn't linpack. I'm rolling with 4.6 until I see scary temps or BSODs.
