0x50 = RAM timings/Frequency or uncore multi unstable, increase RAM voltage or adjust QPI/VTT, or lower uncore if you’re higher than 2x

Is your ram at stock settings and voltage? Load an xmp profile out.

I tried to make 4.7 stable but no matter how I messed with core and vtt voltages it wouldn’t remain stable under 1.4 volts. 4.6 passed intelburntest on maximum with 1.360v but I noticed small instabilities like my sound card stuttering every bit and random programs acting funny. I’d like to put it at 4.6 at least but as nice as it would be to overclock I can’t afford to break my computer. Damn, that was a lot of work for nothing lol.

Short of him having a 24/7 supply of liquid nitrogen, it’s impossible.

Don’t know what you’re talking about. With LN2 you can pretty much do 6.5GHz+ with 2V.

You shouldn’t touch the vtt voltage keep this at auto. Just in short words, your CPU is not capable of doing 4.7GHz. 1.36V is just too much @ aircooling.

Bsod error 0x124? This means for older generations (pre Sandy bridge) up the VTT but for Sandy bridge it means up the Vcore.

Yeah, on liquid nitrogen or helium. Your friend doesn’t have a full time supply to either. You also claimed they were doing it at 1.2v in your initial post, not 2v (which is ridiculous in itself).

So which one is it?

I have set it to disabled.

Something you should definitely not do. CPU thermal throttling is a safety feature and disabling it is absolutely not needed in any circumstance. What it does is throttle you down after you hit dangerous temperatures (100-105° area, not 71°). And if the overclock you’re after requires over 100° temps you’re doing it wrong.

Talking from a personal experience I’ve actually witnessed my i7 3770k throttling down when I upped the frequency from 4.6GHz to 4.7GHz. Precisely when the first core reached 105°. Could run lower freq / lower stress level just fine as long as it stayed below that. And do keep in mind that you shouldn’t be close to these temperatures anyway if you want to stay within the safe limits, generally above 90° would be considered maximum.

Honestly, h200 performs like a top end air cooler rather than a water cooler. This is because it’s a closed loop.

Real water cooling requires a pump and several pipes (I’m sure some other stuff but I’m not really into water cooling myself).

The people that do that get trays of processors, as in 20 or more, to find the one or two units in the batch that can actually do that. Because most can’t. They also usually shut down all but one of the cores and disable hyperthreading. Storage of large amounts of liquid nitrogen is also quite expensive and you can spend up to a dollar a litre, and you need a few litres an hour, so let’s say 36 dollars per DAY to LN2 cool your processor just for the coolant. Mentioning LN2 cooling in a thread like this is utterly pointless.

If you check this topic http://gathering.tweakers.net/forum/…ages/1498406/0 you’ll see a lot of people being above the 6.5GHz with single stage/ln2

You don’t need 20 cpu’s, every ivy bridge should do it with 2V

-5 degrees under full load lol, wouldn’t a phasechanger be a more durable high end cooling solution anyway?
OT: read more guides and ask very specific questions in regards to what goes wrong high end overclocking is actually quite complicated. (MMO-C OC leaderboards can help where possible)

You can’t have any clock @ 2V longer than a week (can’t give exact time) even if you had a bunch of ln2. The chip will 100000000% have electromignation and this will spread like a disease very quick over the die and the chip just dies.

i assume you mean electromigration? also i said nothing about 2V.
instead i started about a very high end cooling solution that isn’t liquid nitrogen. (phasechangers also are around sub zero temps iirc yet require much less work compared to nitrogen setup)

Are you seeing ghosts this time? I havent said he’s planning to get on ln2 and push it more. I just been saying that with ln2 you can go over 6. 5GHz in a general sentence, but doesn’t have anything related with a friend of me.

Hmmm hows that work then because the link I posted is apparently the highest recorded clocked SB ever and knowing IB does not clock higher has me feeling stumped

You’re partly right but keep remind that IB is a 22nm process while SB is a 32nm. 22nm should always clock better regardless of temps. SB world’s record was 6.3GHz? For Ivy 7.1GHz -> http://gigabytedaily.blogspot.be/201…vy-bridge.html

For normal day of use & reasonable temps, the SB just runs cooler while the IB requires less voltage and is like 20° warmer and mostly the cap is already reached.

Which is obviously not true. Sidestepping your initial false info in your later posts as usual, though.

Intel Core i7-3770K ‘Ivy Bridge’ Overclocked Benchmark & Temperature Performance

By Dan Stoltz &bullet;

May 17, 2012

Ivy Bridge Overclocked and Tested Again

It wasn’t horribly long ago that breaking 4GHz with a CPU was left for those with ‘Extreme’ Cooling. In order to push past that 4GHz barrier you needed to run a CPU cooling solution that could bring your processor below the ambient temperature. Whether it was chilled water, Phase change cooling, or something much more extreme like dice (dry ice) or LN2 (liquid Nitrogen) would determine just how far you could push your processor. Unfortunately, cooling like that isn’t as readily available as a custom water cooling loop, or a top tier air cooler like the Corsair A70 cooler that I’ve been using on our motherboard testing over the past year or so. If you were running sub-ambient cooling you know the draw backs to it all to well. Dice and LN2 cant be used as a daily solution since you have to constantly refill the pot. Chilled water and phase change cooling both produce condensation on the motherboard and processor area and increase your chances of water shorting out your system. I’m not saying that it can’t be done, as many have done it, but these aren’t for the average overclocker.

Until recent years, when it comes to Intel processors, just about all of the overclocking was done with the Bclk. Unless of course you have deep pockets and wanted to spend a grand on an Intel Extreme processor that features an unlocked multiplier. If you did have an Intel Extreme processor you could increase the processor multiplier as well as the Bclk when overclocking. This combination of Bclk and multiplier overclocking allowed for great fine tuning when overclocking. Though not everyone has a grand to drop on the extreme processors. In May of 2010 Intel released their first mainstream processors with an unlocked multiplier! The Intel Core i7 875K and the Core i5 655K Lynnfield processors were the first K-series sku’s. Since then, the Intel K series sku’s have become a staple in the Intel product stack. If Intel ever eliminates the K-series processors they may just have a riot on their hands.

Moving past the LGA1156 Lynnfield processors, Intel launched the LGA1155 h3 socket along with their new ‘Sandy Bridge’ processors. This is where overclocking became both limited, and exhilarating at the same time! If you aren’t familiar with overclocking since the Intel ‘Sandy Bridge’ launch in January of 2011, it’s been a trip. Intel all but did away with Bclk overclocking. If you were lucky, you may have been able to find a ‘Sandy Bridge’ processor that was able to handle a 110MHz Bclk. That’s only 10% over the stock Bclk of 100MHz, more than likely you would have a chip that could handle around 105MHz Bclk. Fortunately Intel carried over the K-series sku’s and brought us processors with and unlocked multiplier! The Intel Core i7 2600k and the Intel Core i5 2500k had a maximum CPU multiplier of x59. What made overclocking with Intel ‘Sandy Bridge’ exhilarating was the frequencies we were able to hit! Our first run at Sandy Bridge overclocking we were able to hit 4.8GHz+ on air! Until this point that was absolutely unheard of! Overclocking with the Intel ‘Sandy Bridge’ platform was like a fine wine, it only got better with time! Not long after the initial launch ASUS introduced a feature inside their UEFI BIOS called Internal PLL Overvoltage. The Internal PLL Overvoltage allowed us to push the Sandy Bridge processors further yet.

Now we can jump forward to today. Recently Intel launched the Intel Z77 chipset and the latest and greatest mainstream processors, aka Intel ‘Ivy Bridge’. The Intel ‘Ivy Bridge’ processors like the Intel Core i7 3770k have a number of changes in the architecture that allow it to consume less power and run more efficient. For an in depth look at the architecture of the new Intel ‘Ivy Bridge’ Processors you can check out our full review here. We definitely noticed a couple of things during our testing that are worth mentioning again. The first and potentially most important to most, is that the Intel Core i7 3770K was consistently faster than the previous generation Intel Core i7 2700K. What’s significant about this is that both the 2700K and the 3770K come with an out of the box clock speed of 3.5GHz. Obviously Intel made some improvements to the architecture as well as shrinking the die size to 22nm. If we look back at the power consumption page of the article we can see that the power consumption of the Intel Core i7 3770K is lower than the previous generation when we compare these two processors with comparable clock speeds.

Although the Intel Core i7 3770K uses less power, some would consider that the 3770K has an issue with temperatures. Since the launch of the third generation Intel Core i7 ‘Ivy Bridge’ processors, it has been discovered that Intel opted to use a thermal paste to transfer heat to the integrated heat spreader. The previous generation Intel Core i7 ‘Sandy Bridge’ processors used a little bit different technique to transfer the heat. The ‘Sandy Bridge’ core and the heat spreader were soldered together which is a much more effective means to transfer the heat.

A Japanese tech site, Impress PC Watch pulled their processor apart, and above we can see the TIM used on the third generation Intel ‘Ivy Bridge’ processors. They have also replaced the Intel TIM with a couple others and had seen a dramatic result. At idle they didn’t see much in the way of improvement, under a full processor load though it was a different story. By replacing the TIM, the load temperatures dropped by 11 degrees Celsius at stock settings. They also ran the Intel Core i7 3770K at 4.6GHz and saw a drop of 20 degrees! It’s not clear why Intel choose to go this route, though it doesn’t look like it was the best choice for them. With my little rant being over, we can move on to the good stuff. We are going to take a look at how far we can push our Intel Core i7 3770K processor on air cooling today. We will be using a Corsair A70, which is no slouch when it comes to cooling to try and keep this beast cool under a heavy load!

Instructions for overclocking Core i7-3770K to 4.7 GHz on ASUS Maximus V Formula GreenTech_Reviews

01/14/2013 in Tutorials / Overclocking (overclocking) tagged 4.7 GHz / ASUS Maximus V Formula / Core i7-3770K — admin

Beginner’s guide to overclocking Core i7-3770K to 4.7 GHz on ASUS Maximus V Formula board.

Foreword
Overclocking the Core i7-3770K to the specified frequencies (4. 7 GHz) requires very good air cooling, and ideally a water cooling system. Despite the reduced power consumption, Ivy Bridge processors get hotter than Sandy Bridge processors during overclocking, which is why they require first-class air cooling. nine0005

GreenTech Reviews Administration is not responsible for your actions.

System Assembly
Carefully install the processor into the motherboard socket. The main thing is to align the keys of the motherboard with the recesses on the processor. Do not apply force — the socket is extremely easy to damage. Secure the processor with a clamping device.
Apply thermal paste in a thin, even layer (for leveling, it is convenient to use, for example, plastic cards). nine0008 If you are using a dual-channel set of RAM, then install the modules in the red slots.

As mentioned above, to conquer the frequency of 4.7 GHz, you need a very efficient cooler or CBO. In our case, we will use the unattended CBO Corsair h200i. It is better to install cooling before installing the motherboard in the case — it’s more convenient.

Update the motherboard BIOS before starting the overclocking procedure. To do this, download the latest version from the official website of the manufacturer, reboot into the BIOS and run the ASUS EZ Flash 2 utility in it. Select the downloaded BIOS file in it and agree with the update. There is another option to update the BIOS without an installed processor, RAM and video card — only the motherboard itself, a power supply and a USB flash drive with a BIOS file are required. This technology is called ASUS USB BIOS Flashback. nine0008

Now you need to make sure that the system works stably even in nominal mode. First, go into the BIOS and apply the default settings by pressing the F5 key with confirmation.

Press F10, Enter and wait for Windows to load.
Open the CPU-Z utility, it should display a frequency of 1600 MHz — no load.
Now we run the Prime95 test in the Small FFT test mode and the processor frequency should rise to 3. 9 GHz — the maximum value of Turbo Boost technology for this model. At this stage, you can and should install temperature monitoring software — CoreTemp, RealTemp or Asus AISuite II. nine0008

Well, if everything is in order, then reboot and go into the BIOS.
Remember that instances are different and one can operate at a certain voltage with a frequency of 5 GHz, while the second cannot take 4.7 GHz at the same voltage. Acceleration is like a lottery. But given the motherboard used and good cooling, most processors should be able to reach 4.7 GHz.

Switch BIOS to Advanced Mode.
Set AI overclock tuner to Manual mode. nine0008 Set Turbo Ratio to Manual.
Leave Ratio Sync Control — Enabled.
Set 1-Core Ratio limit to 47. Other values should also become 47.

Enable (Enabled) parameter Internal PLL Overvoltage. This value should increase the overclocking potential.

Enabled the Xtreme Tweaking option, which can improve performance in some applications.

Now let’s move on to voltage.
Since this guide is intended to cover as many processor instances as possible, we will give slightly increased values. As soon as your copy of the processor is running at 4.7 GHz, try to reduce the voltage to the lowest possible. Do not allow the processor to run at high voltage for long periods of time. nine0005

Leave Extreme OV set to Disabled. This parameter is necessary for extreme overclocking of the processor (over 6 GHz), and, as you remember, in our case, overvoltage can damage the processor.
Set CPU Voltage to Manual Mode.
Set the CPU Manual Voltage to 1.35 V. This should be sufficient for 4.7 GHz.

Go to the DIGI+ Power Control subsection.
Set Load-line Calibration to Extreme.

Set CPU Voltage Frequency to Manual and set to 500. This should improve overclocking stability.

Set the CPU Current Capability to 140%. This parameter is necessary to be able to go beyond the standard TDP during overclocking.
Press F10 to save the settings, confirm and wait for the system to boot.
Open the Core Temp, CPU-Z and Prime 95 utilities. During testing, the CPU temperature can reach 90 degrees. This is fine. At this stage, we found out that our processor is able to conquer the frequency of 4.7 GHz without freezes and blue screens (BSOD). During testing, keep an eye on the voltage — does it exceed 1.35 V? nine0008 If the system is unstable, then go to the BIOS in the CPU power management menu and disable C-state technologies. At the same time, stability should increase.

Now, if the system is stable during testing, then you need to enter the BIOS and reduce the voltage by 0.1 V and continue testing. You can also reduce the LLC (load line calibration) level if the voltage exceeds the desired value in the load.
After each voltage drop, check the stability of the system and the readings of the utilities that monitor the temperature of the cores. Again, each processor has individual capabilities. Our copy is capable of taking 4.7 GHz at a voltage of 1.27 V and Ultra High Load Line Calibration. nine0008
