hey guys i have an i7-4790k and corsair 4gb x 2 ram rated at 2133hz (runing at 1333hz) when i bring the ram speed up my cpu temps go up like crazy(5-10c) and i did a Intel stressed test to see if my cpu was damaged in any way and it said my cpu was ruing at 7.1hz. everone knows that is not right... then when i bring the ram boost down it says its running at 4.4hz i need help i know nothing about overclocking id also like to add my motherbroad is auto set to overclock my cpu to 4.4hz. also on my cpu z it jumps from 4.1hz-4.4hz(cpu).

when i bring the ram speed up i use the xmp or whatever that thing is on msi to boost the ram speeds to its rated speed thanks for the replys

temps idle 24-34c with my water cooler nepton 240m
underload ram 1333hz(battlefield 4) 45-65c avg 56c with a/c runing
underload with ram at 2133hz(bf4)59-68c avg 65-66

stock intel cooler
underload (bf4) ram at 1333hz) 77c
underload (bf4 ram speed 2133hz) 80-84

from my understand the auto overclocking on motherbroads are crap i am not sure

Well, remember that the memory controller is on the chip, but I think that fact is secondary. I think you need to take control of the voltage that's going into the chip. I think when you run xmp the mobo is cranking up the juice and causing more heat.
Have you installed the extreme tuning utility that comes with the mobo? Install it, I much prefer using the tool to run my o/c efforts to using the bios.
Go into manual control and change the core voltage mode from adaptive to manual after you've taken note of what the voltage is at in adaptive. Use that voltage number as your starting point. Go down to the ram and set it to your xmp profile. This will force a reboot. Reboot and when windows comes back up, xtu will restart. XTU has both a stress test and a benchmark as part of it, use both of those after the reboot. If you pass both tests, save your results. From this point, you're going to start lowering the voltage on the cpu at small increments. After you lower the voltage, you'll run both the stress test and the benchmark to test things. After you've lowered the voltage a bit, you're going to close the program and reboot the system. When windows restarts, load xtu again and run the two tests. Then start lowering voltage again and continue with the test process. When the system is no longer stable, you'll load the last stable voltage, cause you've been saving your profiles all the while you continue lowering voltage and testing.

The speed of the CPU will vary depending on the number of cores being used. This is how the CPU is configured by default. You can change this in the bios so that when all cores are being used they will all sync and run at the same frequency. My i7-4770k is configured this way.

I have also noticed the increase in temperatures due to RAM frequency. Pretty much the same situation you are experiencing.

You are right about the auto overclocking crap. It supplies too much voltage for the frequency of the overclock presets. Its junk, and you are better off overclocking it yourself. It is really easy, you just need to do a bit of research on the matter before jumping in and changing the few values that you need to change.

I recommend not overclocking until you get an aftermarket CPU cooler.

The cpu going to 4.4ghz is the turbo function,it has nothing to do with overclocking.The extra heat may come from the memory controller being pushed more.The turbo function will cause extra heat too.

What happens when you reset the bios to the optimal default values? After that set XMP to enabled.

Again, Turbo mode is normal. It is designed to jump into turbo mode until its internal temperature reaches a certain level, and then step back down. While this does generate some heat, it will not overheat your system.

And where did you put these new fans. Where is the power for these new fans coming from?

Have you followed the earlier advice to step down the memory power levels manually?
Have you tried doing the same with the CPU?

Soul Slayero,
Read my original reply. It will solve your problem. It takes some time to properly undervolt your chip, but it will actually get your settings to a point where over clocking is a snap(add .05 volts and .1ghz at each step). It will also keep your temps stable and lower them in the process. The reason your temps are swinging wildly is due to the voltage that the system is sending the chip in auto voltage mode.
The last good reason to follow the steps I gave you is you'll find out if you won the silicon lottery. You don't need to clear your cmos, that's not the problem.

Ok there appear to be a number of things wrong here.

To start, you should never use an overclocking program from Windows. You should overclock via BIOS, or not at all. Second, you need to manually set voltages, or you may burn up your CPU.

RAM shouldn't have that much of an effect on your CPU temperature whatsoever. What concerns me is that either via BIOS or Windows, however you overclocked using "auto" settings, you may be sending more voltage neccessary to your CPU and thereby causing the temperature to go up.

I am sure your RAM is running at 1.65V, which arbitrarily overclocking with an "auto" feature may be once again sending more juice than you need to your PC.

So now about the solution:

Start by restoring BIOS to Fail Safe Defaults/Factory Defaults. There should be an option within BIOS for this.

Now read a few guides on the internet how to properly overclock your CPU. Now slowly do the trial and error method of properly overclocking your PC.

After you have done this, including stress testing and making sure your PC is stable, go to overclock the RAM.

I personally would just try to get the RAM to run as fast as possible at 1.5V, but that's me. This can be done by looking at other modules from your chosen manufacturer, and manually setting timings and RAM. There is minimal if any gains past DDR3 1600mhz. You may see a single digit FPS increase from 1600 to 1866 or 2133, but I would personally not overvolt my PC in order to get there. In all honesty you will probably never notice the difference.

Android,
You've never used XTU have you? It's very user friendly and has a built in stress test and benchmarking program. It's easy to save among other nice features. Far simpler than using the bios, which is an important factor here.
Manually tuning ram is imo above our OPs skills at this point. Granted it is largely a time issue to get them all set.
I'm wondering how long you plan on having your system run. What's your upgrade cycle? I'm not saying you're wrong in regards to ram voltage, to each his own, but you do have a very conservative view on the issue.

No I refuse to use XTU, or any other overclocking software program. Call me old fashion, but yes I'm a conservative overclocker, I keep voltages as low as possible, and my average system lasts 6 years often enduring a minimum of one GPU upgrade over the duration. Needless to say I have been building my own PCs for around 15 years.

From my experience overclocking, every software program I have ever seen sends more voltage than necessary for a stable overclock. As a matter of fact, the factory default setting for CPUs within BIOS actually send more voltage that required as well... Example : the Q6600 I had in my last build I actually Undervolted from factory setting, and Overclocked it at the same time!!!

I look at overclocking as somewhat of an art. I don't push components as fast as they can go. Ivy/Haswell have an "voltage wall" whereas they take more voltage than reasonable to get past a certain point. For example I can get my i5 3570K rock solid stable at 4.3ghz with no WHEA errors at around 1.24V. I got it to boot at 4.6ghz fine, but anything at 4.4ghz or greater takes a HUGE spike in voltage to get stable, and in my opinion it's not worth it.

But my last remark on your comment that the OP may not have the skills, I disagree because honestly it would only take a few hours of research to get what he needs to know from our friend Google. Once again, it's just my opinion, but a few hours or research is worth the trouble to have a rock solid stable system and not have to worry about additional problems or burning up components faster, and the potential for more problems later in the long run.

If you aren't willing to invest the time I would just recommend not overclocking whatsoever, or pay someone else who knows what they are doing to overclock it for you. The 4790K runs at a respectable 4.0ghz anyway, are the gains of using an overclocking program effectively making your system unstable really worth the trouble?

Anyway, there's my two c
