Cpu Overclocking..

[XxwonderbredxX]

Hey guys!

 

Well recently I overclocked my i5 3570K CPU. It's speed out of the box is 3.4 GHz. I overclocked it to 4.1 GHz. And It's running great!

 

The question is! What temperature should my CPU and MOBO NOT go over!? On average the CPU is at around 92-110 Degrees Fahrenheit. And my MOBO Less than 105 Degrees Fahrenheit. THE HIGHEST CPU TEMP I've seen it get to is 120ish Degrees Fahrenheit.

 

My MOBO is a ASROCK Z77 Extreme 4.

 

My cooling is pretty good. I have two case fans, and my CPU cooler is a Cooler Master Hyper 212 EVO.

 

Thanks!

Heres a helpful guide to get an easy 4.5ghz

Rule for ivy chips is to never go above 80 degrees. You can of course but it is not recommended.

Keep your full load temps (aka blend test with prime 95) below 70-80.

I assume you kept your voltages at stock to get 4.1 so your temps shouldn't have changed.

So you're saying that I should no be running my CPU at the Temp I'm running now. Wanna see a picture of my temp, and voltage readings?

Yes please. 90 is the heat wall for that cpu (actually depends on the mobo) but your board may force a shut down before 90. Above 75 24/7 may shorten the life of the cpu.

Post a cpu-z shot. I run mine at 5.1 ghz, but its watercooled and at 1.4v

[BranHorse]

I am using units of Celsius btw.

Never go by Fahrenheit when referring to electrical components haha

That's not running any games. That's just me on Google Chrome and stuff

 

This is with CS:S, and Google Chrome running.

OH! I never knew well then I'm never really going over 42 C.

Yeah you are well in the clear haha.

Some things to know though, read the guide posted above, do not run on an overclock without stress testing.... I can boot my rig up to 5.2 ghz but as soon as i load prime I crash to oblivion haha.

To stress test download this (64 bit) http://www.guru3d.com/files_details/prime95_download.html

Run the blend test and just let it go. Close all other programs except for cpu-z and hwmonitor

(links for both http://www.cpuid.com/softwares/cpu-z.html)

Cpu-z is the only program that is accepted by hwbot (pro ocing etc) so use it XD

Monitor your temps closely while prime runs. It makes every core run at 100%

You should run it for 24 hours but id say a solid 12 is fine. What I do is turn it on before i got to sleep and watch it for 15 minutes. If the temps are safe then go to bed. If they are too high then lower the vcore/overclock.

When you wake up your pc should be at the same temps with prime still running. From here you can call it good and turn off prime 95. This will mean that your oc is stable and you wont have any unexpected crashes.

Now if your oc is not stable and the pc has restarted or crashed (will reboot if it overheats/has stability crashing) then you need to tweak more.

The guide i posted above is the best place to start and is very basic. Read up and you can easily get it to 4.5ghz with your cooling. After that you may need some more tweaking and voltage which is where you start to run hot.

Just do not forget to stress test.

 

Also your temps are a little warm for stock vcore. May need to re mount the heatsink, but I would do a prime 95 test first and see how warm it gets.

Okay awesome! I'll do the tests tomorrow! And I'll let you know how it went.

BUT what do you mean by "Also your temps are a little warm for stock vcore"

40c is fine if your upping the voltage on the processor, but you haven't yet. Stock vcore should be around 30c when idle and 40-45 when under load. But i do not know the circumstances in which the photo was taken.

Voltage determines the heat of the cpu not the actual speed of the cpu. So if I got a chip to 5 ghz without changing the vcore then there would be very little change in heat. But if i upped the vcore to make it stable then it would run hotter. sandy ivy and haswell are incredibly easy to oc compared to the older chips. To get them stable you just gotta up the vcore. (>4.6ghz) greater than that and you gotta tweak ram etc)

Just when you start uping the vcore make sure you stay under 70 c under a full load aka prime blend test.

Hey guys!

I have that same processor and motherboard, love them both.

[IvoryG37]

Most ivy bridges can run 4.2 at stock voltage. You should up it to 4.2

[Crackdaddy]

I definately wouldn't trust them temp readings if the core temp is the same as the motherboard temp, I don't think thats even possible.

This is how I overclock it, push it until you can't run prime for 30 minutes, then bump the voltage .1 and try again. If its a success, keep pushing. Once you've reached the ceiling, then worry about keeping it cool with a 212 or a water cooler. The reason I say this, is if you've got a hot chip with little headroom, you may want to save your money on aftermarket cooling solutions and just go for a mild oc with factory air. After oc'ing since the days of the 33 mhz pentiums, I can tell ya, stability is the most important thing to me. Running 5 ghz don't mean much if your computer reboots everytime you do something cpu intensive.

Both his temps are fine....

[Crackdaddy]

Yes they are. But if the core temp is the same as the ambient temp, the core temp sensor is not accurate.

[BranHorse]

Yes they are. But if the core temp is the same as the ambient temp, the core temp sensor is not accurate.

With proper cooling this is doable.

Also 34 c = 93.2F which is very hot for someones ambient room temps to be in the winter...

The NB/SB of the board runs at a hotter temp then ambient and they rarely change. There is a heat transfer going on thats why they put the unnecessary HSF on them...

My room is about 20c atm and my cpu idle is at 24 c. My mobo on the other hand (stock cooling no waterblock on it) is at 30 degrees because it lacks the cooling that my cpu has. But now days you do not touch the NB and SB clocks when Ocing under 4.5 ghz on ivy chips so there is no need to cool it lower than the stock .

TL;DR his temps are fine. The mobo temps will not change with oc. If he ups the voltage on the vcore then the cpu temps will go up (or if he runs a stress test) while the mobo (nb/sb) temps will stay the same.

I know right! I love them too! I had them since last Christmas. How long have you had them?

 

Most ivy bridges can run 4.2 at stock voltage. You should up it to 4.2

Yeah, So should I even bother testing it?

 

Both his temps are fine....

So should I still test it? Cause I mean the CPU says it can be overclocked to 4.2. So shouldn't it be good without needing to be tested? I mean, I dropped my GHz back down to stock (3.4GHz) and it was running about or a bit less than the overclocked 4.0GHz that I'm now running.

If its oc'd then you test it.

The cpu may be stable or it may not be. Each chip is different. Run a blend for 30 min then call it good. No need to 24 hour it if you not touching the voltage

Which program do I used to blend test it? I have both programs installed. I just don't know which one to run. Prime? Or CPU-Z?

When I'm testing Shut down every program except the testing program.

[BranHorse]

prime.

Use cpu-z to monitor voltages and cpu clock. AKA make sure the clock speed of the cpu doesnt change. That would mean intels stuff to throttle the cpu is still on

Same, I ordered it all last November during Black Friday sales. The stuff has been great but I am going to be RMA'ing the motherboard here soon because it is having an issue where my USB's don't all turn on with the pc.

Have you flashed to latest bios?

This has happened with every mobo I have ever bought haha. Updated bios usually fixes it.

Sweet! and woh. that blows.

Dude, I been slackin' on dat. Soon. xD

No I haven't. I can install OS and fix random driver issues and shit but have never done a bios flash. I'll google instructions and get on it. Thanks man.

 

I have version 2.00 http://www.asrock.com/mb/Intel/Z77%20Extreme4/?cat=Download&os=BIOS

 

Do I have to update each one of those? There are like 20 updates for my motherboard. Which one would I need? I see where they addressed wireless keyboard and mouse issues in one of the updates. Will that very top on include all the stuff in the downloads below it?

Yes it will. Just flash to the 2.90. Make sure to read the instructions there is a slim chance that you can brick the board if you mess up (hard to do).

Follow the instructions and you will have nothing to worry about.

It seems that the usb was fixed with bios 2.4 and above so the 2.9 should fix the usb issue you have.
