What is Devils Canyon?
Devil's Canyon is the title given to Intels 4th generation Haswell Desktop unlocked processors that run on socket 1150 motherboards. There are two CPUs included under the Devils Canyon name; i5-4690k and i7-4790k. Both processors have identical core/thread count to their haswell counterparts; 4c/4t and 4c/8t respectively. Both the i5-4690k and i7-4790k feature an unlocked CPU multipler up to 80x base clock.
Why should I be interested in Devils Canyon?
There are several new improvements on Devils Canyon vs previous Haswell processors.
New Thermal Interface material (TIM). Intel has stated that the new DC cpus will now feature better thermal material used between the Integrated Heatspreader and the CPU die, which is good news since ivy Bridge and Haswell CPUs both suffer from unusually high temperates vs Sandy Bridge CPUs when overclocked past a certain point. This is due to the poor IHS contact and inferior TIM.
Enhanced Performance and Overclocking. The new DC CPUs are advertised as being sold with overclocking in mind, and recently screenshots have appeared on the internet showing the i7-4790K has a stock core clock of 4Ghz. This would be the first Intel CPU to feature a stock core clock of 4Ghz and could potentially mean higher core frequency overclocking.
Supported by Intel 9 chipset. Intel have been vague up until now as to wether or not the new DC CPUs are compatible only with the new Intel 9 series chipset (Z97). However recent rumours have surfaced that indicate that it is potentially possible to run the DC CPUs on the current 8 seies chipset (Z87). Again, this has not been fully confirmed if all current Z87 motherboards will support the new cpus with a simple BIOS update.
When is Devil's Canyon available?
Devil's Canyon has been available in the UK and from European stores since Friday 20th June on a limited basis, and has also been available from Monday 23rd June in the USA.
What motherboard do I need to run Devils Canyon? (Z87 or Z97)
Please use the Intel Desktop Compatibility Tool to check which motherboards will run the Devils Canyon CPUs. Fateswarm has made a very informative post compiling information with regards to VRM information on various Z97 motherboards, and details the benefits of a wide range of motherboards.

Quick word on the above stress tests - These stress tests are various tests tried and tested by OCN members. There is no definitive word on which is the best or which any one will guarantee you the ultimate stability. Up until Haswell I have always ran prime95 vigirously, but I have since been made aware prime95 is extremely difficult on Haswell. As such I can only comment on the stress test I have used and give my experience on this.
Disclaimer! Please ensure you have the appropriate hardware in your pc before following this guide, i.e dont use a cheap stock intel cpu cooler or a cheap power supply/motherboard etc etc. This guide pushes your cpu hard and you need good quality parts in your system before overclocking the cpu! Overclocking is your responsibility, I accept no liability for any hardware damaged through the use of this overclocking guide. By following the information in this guide you are accepting you understand the above disclaimer.
Please bare in mind that no two CPUs are the same regardless of batch number; just because CPU A can do 5ghz at 1.4v doesnt mean CPU B will do the same. Please bare this in mind when overclocking your cpu.
OK! Onto the overclocking.
This is a quick overview of what this guide entails:
Step 1. Decipher your stock CPU VID. (Beginning this step assumes you have all the required components in place, i.e Good CPU Cooling, quality components in your computer etc).
Step 2. Begin overclocking process.
Step 3. Stress test said overclock.
Step 4. Continue overclocking until successful or temperature/voltage limit is reached/
Step 5. Return to step 3 after adjustments if overclock is unsuccessful.
Step 6. Enjoy your overclock!
How to find out your stock CPU VID.
Turn on your PC and boot into the bios. Once inside the bios, load optimized defaults. This will reset everything in the bios to stock. Next locate all the power saving features namely EIST, C1E, C3/C6 and DISABLE all these features. What this does is ensure that the CPU is running completely without any downclocking of the cpu multiplier or voltage. Once you have disabled all the power saving features, go into the VOLTAGE section of the bios and look next to the CPU CORE VOLTAGE or CPU VCORE. The setting should be at auto, but there should be a number to the left of the AUTO setting, 1.10v for example. This number is your CPUs VID and is a predetermined voltage set for your cpu.
Once you have done the above, proceed to boot into windows and open up cpuz, hwinfo and realtemp. Here you should be looking at your cpu temperatures and ensuring they are in the normal range, i.e not running at 50c with the cpu being at stock. Also please double check your cpu multiplier and cpu vcore in hwinfo/cpuz. This SHOULD be at 4.4Ghz, and the multipliers should be from 44 to 40. If the cpu vcore is showing at something like 1.4v, please go into the bios and double check the amount of cpu vcore, this is a bug on Z97 Gigabyte motherboards. This should be remedied by going to optimized defaults, or you can try to flash your motherboard to the latest bios from your manufacturer's website.
Beginning the CPU overclocking process.
Ok, now that you have your stock VID amount noted down, and all cooling aspects in order with respect to your cpu, its time to begin the overclocking process. Now there are several ways to go about this, personally I would choose my target cpu speed and then go from there.
For these instructions, the test assumes I want a core speed of 4.6Ghz.
Locate the CPU Frequency settings in bios and start by changing the CPU Multiplier to your desired amount. So for 4.6Ghz enter 46, since the base clock is set to 100mhz and the cpu multiplier would be 46, giving you the final clock speed of 4.6Ghz. Now you will also notice the core unclock frequency, there is no need to change this from stock, so leave it at auto. Also the System Memory Multiplier setting is present, this determines the speed of your memory, so 16.00 gives you memory speed of 1600mhz, 21.33 is 2133mhz and so on. Again leave this at stock for now since we want to concentrate on the cpu core speed.
Also remember at this point to manually enter your RAM speeds and voltages. These can be located under the Advanced Memory Settings, you will need to enter your timings, such as 10-10-10-30 and also enter your RAM voltage under the section DRAM voltage. Again go by what the information is on your RAM sticks. Some people prefer to use XMP profile for their RAM, this is where the settings are automatically entered into your bios as to what your RAM should be running at; but I prefer to manually enter the settings since XMP doesnt always work.
Now you will want to adjust you cpu vcore, so start at something light such as 1.20v.
You can now go ahead and attemtp to boot into windows. There is no need to change any other settings at this point assuming you are running your ram at stock and the uncore frequency is also at stock. If you cannot boot into windows, either because windows hangs or you get a Blue Screen of Death (BSOD), then restart your pc and increase the cpu vcore until you can boot into windows.
Stress testing your overclock
Once you are in windows this is where it gets interesting, stress testing. If you are going to be overclocking your CPU it is vitally impotant that you do some form of stress testing so that you can at least have some reassurance that your pc will not BSOD unexpectedly. There is nothing worse than being in the middle of a game or important document only to have your pc shut down unexpectedly. Whilst stress testing is a good indicator of stability, it is not a definitive 100% assurance your pc is stable, there is no stress test available that can prove this.
My personal choice for stress testing my i7 4790K has been to use the Intel Extreme Testing Utility, [email protected] (distributed computing), and AIDA64. The reason I have not chosen to use Prime95 is that it is incredibly tough on Haswell processors for some reason. Whereas before prime95 was very useful for Sandy and Ivy Bridge CPUs, I have tried and failed miserably to use it for Haswell. If you choose to use it on Haswell that is fine, but it may prove to be alot more difficult than the other stress tests mentioned here.
Now for the stress test I used Intel XTU, which is pretty self explanatory, just open the programme and decide how long you want to run the stress test. AIDA64 is another stress test, again open the programme, go to tools then select stability stress test and press start. I decided to run both of these tests for around 10 hours, you can do less or more its up to you. I would recommend at least a few hours for whichever stress test you choose.
Please ensure you monitor the cpu voltage and cpu temperatures throughout the stress tests to make sure they dont go into dangerous amounts. You can monitor your cpu vcore and cpu temp in hwinfo, located under the sensors setting. The vast majority of people recommend staying under 1.4v cpu vcore and I would say stay under 85C during stress tests if possible. If you are getting higher than either of these amounts, then you are close to the limits of your chip. Once your CPU goes over 90C it might possibly shut itself down to prevent any damage.
Ok, so once you have started your stress test either you will get to the desired length of time for the test and pass, or your overclock will be unsucessful in one of many ways:
BSOD - not enough CPU vcore or Try increasing your VRIN Override voltage, dont go over 2.1v but keep within 0.4v - 0.6v of CPU vcore.
Stress test hangs - Not enough CPU vcore or Try increasing your VRIN Override voltage, dont go over 2.1v but keep within 0.4v - 0.6v of CPU vcore.
Temperature/voltage too high - Stop the stress test and lower your overclock and then try again.
Struggle to boot into windows even after increasing CPU vcore - Try increasing your VRIN Override voltage, dont go over 2.1v but keep within 0.4v - 0.6v of CPU vcore.
Success - You have passed the test to your desired time. You should now proceed to restart your PC and go into the bios and save your overclock profile.
It is also advised that lowering the CPU Uncore frequency can help with CPU Multiplier overclocking, so you can attempt to lower this amount if you are struggling with your cpu's frequency.
Overclocking the CPU Uncore Frequency/Memory Overclock
The CPU Uncore Frequency overclocking is much the same the CPU multiplier overclocking process. Increase the Uncore Frequency to your desired amount, boot into windows and begin the stress testing process. To overclock your memory simply increase the System Memory Multplier and or your Memory Timings and then begin to stress test as above Use AIDA64's System Stability Test and chose Test Cache to test the Uncore frequency, or stress Memory to test your RAMs overclock.
If the cache stress test hangs, you get a BSOD or your PC shuts down, either lower the uncore frequency or increase the CPU Ring Voltage. Personally I would stay under 1.2v on this but others may advise you to go higher. If you fail the memory stress test, you can either increase the DRAM voltage or the System Agent voltage to help stabilize the memory overclock.
Again, remember to monitor the temperature and voltage of your CPU throughout this process.
Power Saving Features
After setting your overclock you might want to downclock your cpu to save power. The following settings can be used to save power when overclocking once enabled:
EIST dynamically scales voltage and frequencies at load
C1E scales voltage and frequencies at idle
In conjunction with C3/C6 which also save power through use of downclocking the core and decreasing cpu vcore.
