Skill TridentZ 16gb 8gbx2 ddr4 1. I would like to try to aim for that if possible as a goal and maybe on the Trident Z ram. Any help for a noob? Thank you in advance! Last edited: Jul 29, Apr 20, 99 Lyfer said:. Oct 31, 4, 37 Here is a good starting point.
Tip: Dont forget to press enter when manually entering values in the bios to be sure the value "sticks". Under the Monitor Menu Q-fan control Disable all of them to run your fans at full-speed while testing if you want Aida 64 Extreme can be used free for 30days, so thats plenty long for testing. When viewing voltages in HWMonitor be sure to observe where your voltage "settles at" after 5mins under loadthat is the value you are trying to set.
If you do, try upping the following voltages. Asus rep says you can go as high as the following to fix the issue Some bios updates automatically set it to and removed the option to manually set this all together, so if you cant find it don't worry about it.
Wow thank you so much! CFP Senior member. Apr 26, 6 One thing that tripped me up was getting my ram to mhz. Ended up ordering this.The how, what and why questions that surround overclocking often result in answers that either confuse or dazzle, depending on the mind-set of the user listening. At the end of the day, it originated from trying to get extra performance for nothing. Buying the low-end, cheaper processors and changing a few settings or an onboard timing crystal would result in the same performance as a more expensive model.
When we were dealing with single core systems, the speed increase was immediate. With dual core platforms, there was a noticeable difference as well, and overclocking gave the same performance as a high end component. However in recent years, this has changed. Intel sells mainstream processors in both dual and quad core flavors, each with a subset that enable hyperthreading and some other distinctions. This affords five platforms — Celeron, Pentium, i3, i5 and i7 going from weakest to strongest.
Overclocking is now enabled solely reserved for the most extreme i5 and i7 processors. Overclocking in this sense now means taking the highest performance parts even further, and there is no recourse to go from low end to high end — extra money has to be spent in order to do so.
As an aside, inIntel released the Pentium G, an overclockable dual core processor without hyperthreading. When we testedit overclocked to a nice high frequency and it performed in single threaded workloads as expected. With software and games now taking advantage of multiple cores, having too few cores is the bottleneck, not frequency.
Unfortunately you cannot graft on extra silicon as easily as pressing a few buttons. One potential avenue is to launch an overclockable i3 processor, using a dual core with hyperthreading, which might play on par with an i5 even though we have hyperthreads compared to actual core count. But if it performed, it might draw away sales from the high end overclocking processors, and Intel does not have competition in this space, so I doubt we would see it any time soon.
But what exactly does overclocking the highest performing processor actually achieve? Our results, including all the ones in Bench not specifically listed in this piece, show improvements across the board in all our processor tests.
Here we get three very distinct categories of results. In both of these there were benchmarks that bought the average down due to other bottlenecks in the system: Photoscan Stage 2 the complex multithreaded stage was variable and in Linux Bench both NPB and Redis-1 gave results that were more DRAM limited.
Meanwhile, all of our iK overclocked testing are now also available in Benchallowing direct comparison to other processors. Other CPUs when overclocked will be updated in due course. Moving on, with our discrete testing on a GTXour series of games had little impact on increased frequency at p or even SoM at 4K. Finally, the integrated graphics results are a significantly different ball game.
When we left the IGP at default frequencies, and just overclocked the processor. The results give a decline in average frame rates, despite the higher frequency, which is perhaps counterintuitive and not expected. The explanation here is due to power delivery budgets — when overclocked, the majority of the power pushes through to the CPU and items are processed quicker. This leaves less of a power budget within the silicon for the integrated graphics, either resulting in lower frequencies to maintain the status quo or by the increase in graphical data occurring over the DRAM-to-CPU bus causing a memory latency bottleneck.
Normally this would be mitigated by increasing the power limit on the processor as a whole in the BIOS, however in this case this had no effect. Taking Shadow of Mordor as the example, raising the graphics frequency not only gave a boost in performance when we used the presets provided on the ASRock motherboard, but also the issue of balancing power between the processor and the graphics disappeared and our results were within expected variance. Conclusions The how, what and why questions that surround overclocking often result in answers that either confuse or dazzle, depending on the mind-set of the user listening.
Unfortunately, we hit a wall quickly, despite some extremely high voltages. The CPU finished our stress test at 4. Dropping to 4. In the end, whatever voltage is set in the BIOS only serves as a target that gets adjusted by the firmware depending on load and sensor readings. The following two graphs illustrate average power consumption during idle, gaming and stress testing.
The 61W gaming measurement gives you an idea of what overclocking might look like if you want to squeeze every last bit of performance from this processor. So what happens when the Core iK is taken to its limits?
The core voltage required to achieve that number is equally gargantuan. So, between the massive waste heat and our high-end cooling, what do the temperatures look like? We averaged all of the cores together as reported by the sensors for each measurement interval and split them into our various workloads. The results fluctuate according to the gaming load's variable demands. During the stress test, however, temperatures become a lot more consistent, resulting in a smooth curve.
By measuring the temperature of our water, we can see that a good open-loop solution shouldn't have any trouble keeping the Core iK cool. The CPU will destabilize long before thermal throttling becomes an issue. Intel's Core iK is fairly efficient at its stock clock rates.
The Intel Skylake i7-6700K Overclocking Performance Mini-Test to 4.8 GHz
While it's possible to push this chip all the way to 4. Air cooling is really only an option if you run the K at its stock frequencies. A simple closed-loop liquid cooler is needed to step up to 4. For example, a Corsair Hi that we tried was overwhelmed after just 12 minutes, after which the processor throttled due to core temperatures in excess of 90 degrees Celsius. The amount of waste heat generated by an overclocked Core iX is manageable.
But for Broadwell-E, better heat management is a must. Resulting Power Consumption The following two graphs illustrate average power consumption during idle, gaming and stress testing.

Cores were reaching 72C back when I had the voltage at 1. Perhaps I have more headroom for OC than I thought?
So I used the AI suite for the first time, and 5 way optimization. CPU temp is up in the 60's at this temp, might just drop it back down to 4. Quite happy with that. Hi Chino. In cpu-z it says Core VID 1. My question is how come its like that in cpu-z?
And my voltage seems almost to low, is it right or is everything ok? Last edited by Woodmansee; at AM. The K doesn't have Hyperthreading so it's normal that it requires less voltage for a certain overclock.
But then again you might have a good CPU assuming you're stable at 4. Has anyone figured out the max safe voltage for the k? Last edited by Kenrou; at PM. CPU: ik 4. I'd keep Vcore below 1. Yes, that's what the specs say. Depends what loads you are putting on your rig.Our overclock testing showed that 4. With a new motherboard and the same liquid cooler, the same processor that performed 4.
In this mini-test, we tested our short-form CPU workload as well as integrated and discrete graphics at several frequencies to see where the real gains are. In the Skylake review we stated that 4.
Both ASUS and MSI have also stated similar prospects in their press guides that accompany our samples, although as with any launch there is some prospect that goes along with the evolution of understanding the platform over time. Starting with the 4. Enough of the babble — time for fewer words and more results!
We actually got the CPU to 4. Voltage is read incorrectly on the right. OK, a few more words before results — all of these numbers can be found in our overclocking database Bench alongside the stock results and can be compared to other processors.
There is also an added issue of the motherboard remaining consistent, depending on how the motherboard manufacturer wants to add in their own boosting technologies over the ones that Intel would prefer they used.
In order to remain consistent, we implement an OS-level unique high performance mode on all the CPUs we test which should override any motherboard manufacturer performance mode. Thank you to G.

Thread starter sneakyvtr Start date Mar 31, Hi all, Successfully managed to get my 4. Geekbench 3 results looking pretty good so far! For those who struggle to get their overclock into OS X, keep tinkering it is worth the effort in the end!
Hi, These are nice scores. Can you be more specific about your overclock? What did you do exactly? What CPU cooler are you using? Mine wont show so I dont even know if its working in OSX, but its fine in windows.
Yes, my overclock is visible in the Intel gadget. I did all my overclocking in the BIOS. I don't have Windows.
Intel® Core™ i7-6700K Processor
Can't help you much, my Zx is quite different from yours. Yeah I did all the overclocking in the bios too, thats not the issue, the problem is that it wont show up on intel power management in OSX and its driving me mad! I suppose my question is more toward the OP who has a similar motherboard to me. Of course. The Asus ZA made overclocking easy. CPU voltage is currently at 1. That is literally it once it booted I began stress testing to find the lowest stable voltage.
The CPU cooler the system is running is a Corsair Hydro Hi GT which although expensive is an incredible piece of kit and keeps my temps very low indeed.
