Hi,

Just DIY-ed my desktop last week.
I have been getting random half second freezes in all my games.

My setup is:
I7-4790K
Asus Maximus VII Hero
Gigabyte GTX980
Cosair AX760 power supply
Cosair Vengeance Pro 16GB 2133MHZ

 

i checked with gpu tweak and the gpu, processor and memory clocks suddenly drops for a split second when this happens before returning to normal.
other stuff like temperature remains the same.
I've been on google looking for a solution but have yet to find one.
Any clues?

Thanks in advance.

Download HWmonitor and watch your temps and voltages: http://www.cpuid.com/softwares/hwmonitor.html

 

It is possible that your psu has an issue, it is rare but even brand new parts can have problems. Are you using the stock cooler on your 4790K? Are you over clocking any component?

 

If you are running over clocks, default everything to stock and see if that solves the issue, then go back and overclock one component at a time.

thanks for the reply!

 

only things overclocked are cpu to 4.6 1.25 volt and  ram from 2133 to 2400, rest was stock.

i was using asus gpu tweak and had no change in temp.

i will try with hwmonitor.

what should i watch out for?

yes stock cooler as well.

 

i will try to set everything to stock in a little bit and see how it goes.

if it still happens, what do you think are the possible reasons?

 

sorry for the many questions.

pretty crap at these things

There is no way a 4790k will overclock to 4.6ghz stable with a stock cooler. Remember that idle temps and full load temps are going to be very different, an OC chip at idle vs a stock chip at idle may very well have the same temp. It isn't until you load it that the temperature will rise. You can try to run Prime95 and then watch the temp closely.

 

What you should watch is the temperatures of the cpu and the voltages on the 3.3v, 5v, and 12v rails. They should stay within 5% from the correct voltages.

If you intend to overclock the cpu you need to upgrade the cooler to a large air cooler or better yet liquid cooling. I have not overclocked a 4790k yet but I have my 4770k. I can tell you that reaching 4.6ghz stable would require water for my chip. The furthest I can go is 4.4ghz on my evo 212 air cooler and that is pushing the max temp limit when at full load.

 

ALWAYS test temperatures for overclocks at 100% load or very near. This way if the cpu ever ends up at full load you know it won't overheat.

ok i just checked with my friend who put it together for me.

its not a stock cooler, using corsair h100i.

 

idling at 4.6ghz is 30-32 degrees celsius
aida64 full load for 2 hours under 80 degrees celsius

Ok,

 

I would run prime95 and have HWmonitor open and running at your OC speed 4.6ghz. Let prime 95 run for at least 30 minutes, see if the temps stay under 85C, that would be the highest I would go personally, it isn't the max for the chip but it is always better safe than sorry.

 

If prime95 is stable, no crashes, freezes etc, and the temps are safe, then you should be ok cpu and ram wise. Also watch the voltages as mentioned before.

 

Generally when clock speeds change suddenly it is a heat issue or power issue.

You can use aida64 instead of prime95 if you still have that installed, either test should work the same.

thanks i am doing that now using aida64 to see how it goes.

 

my friend told me he did a stress test and everything remained fine.

max temp was around 78 and core voltage was around 1.2v but he can't remember what the other 3 values that u mentioned were.

 

does it seem that one of my parts has a problem?

It is tough to say currently. What game was having the issue?

 

If you have not done so already, update all of your drivers (double check they are all installed in device manager).

 

Sometimes it is just one missing driver that causes problems, in device manager, you should not have any yellow ! or ? marks.

dota 2 and witcher 2.

no other games currently installed.

 

yep all drivers are updated.

real late over here so ill just do a test with a game tmr and see if its still the same after setting back to default

It wouldn't be a bad idea to try a different gpu. Since this is a new build I will ask if you used standoffs for the motherboard: http://en.wikipedia.org/wiki/Standoff_%28separator%29

 

Some cases need them, some have them built in.

 

Did you try the games with everything at the stock clocks (no overclocks)?

 

You could try adjusting the adnvanced power options to high performance.

 

Did you install a new ssd or hard drive with this computer?

yes the case comes with standoffs.

 

all games tried with stock clocks.

 

just adjusted the power options.

it was on balanced.

 

ssd, hard drive and everything else was brand new.

If the power options change nothing, I would run HWmonitor in the background (open it and let it run) and then play games. Then verify the voltages stay within specs, you can take a screen shot after playing games of the HWmonitor window and post it here or link it here from a dropbox account.
