new build--1st OC

[wytnyt]

just got around to tinkering with my new build and with my H80 on medium [hate high w/full fans] i got it to run decent temps at 4.3 on 100 % load

im curious how well itll run with the pump set high and after i get the cooling finished

[HOODedAssault]

Man ivy bridge gets hot when overclocked, my 2500k doesnt even hit that after hours at 4.7 1.37v on air.

[wytnyt]

their a different breed of cpu's,my 2600k will also run cooler under a full load but this 3770 will run circles around it,especially with video encoding.
the ivy bridge tj max is 221 f whereas the sandy bridge is 208 f.
so its like comparing apples to oranges.
these temps arent that far out of line even tho 32c under a full load would be nice

without knowing what the ambient temperature is.. your OC looks fine for a vcore of 1.25v. have you tried 1.175v yet? it should lower the temps a couple of degrees.

my ambient temp was 34c
new to oc so ill have to read up on how to change the vcore
also waiting to finish the cooling setup
this oc was run with h80 profile on medium

That's a bit toasty for 4.3GHz, like others have said, try dropping your Vcore a bit.

To find the right setting, try looking under Advanced (Press F7) and looking in AI Tweaker for the Vcore settings, and see if you can't knock it down a touch.

And if I was you, I'd set the pump on high and leave it there, you should see another couple of degrees Fahrenheit drop in temp. (Not used to Fahrenheit, prefer Celcius when working with temps, nearly mistook the temps for Celcius and almost cried at how hot it was running xD)

Edit:

Also, the Asus P77 series motherboards don't exist, there's the Q77, H77 and Z77, but no P77 Pro, at least, not as I could find, which might be why you couldn't find your motherboards UEFI settings. ^___^

sorry its a ASUS P8Z77-M PRO- LGA1155
im waiting on a link as i dont like to
run it on high all the time

Ah right, no worries ^___^
Well that's up to you, but I've always seen with all in one watercooling systems that you get best performance when the pump is running at its highest setting, and that only the custom loops can get away with slower speeds cause of their greater efficiency and power. :)

And with you getting quite high temps at a fairly modest OC I would say for now run the pump on high, they're not that loud afaik, so it might benefit you to run it like that, but so that your comp doesn't sound like a DC10, run the fans on medium, or even better, get some Gentle Typhoons in Push/Pull :)

Mind you, having said all that, you're not exceeding the thermal safety spec of the processor, it's just a little high for 4.3GHz. I'd typically like to see somewhere around 65C at that on Ivy Bridge with a H80 give or take a few degrees :)

Also, have you tried reseating the cooler and applying some MX-4? You could potentially see up to a 5C drop in temps when it's applied correctly. :)

Edit:

Not that me or anyone else are belittling your OC btw, for a first attempt, that's damn good, it's just that we'd like to try and get your temps down, cause your processor will last far longer if you do, and you'll not feel so disappointed when you see others getting much higher OC's at the same temps.

And if you can get your temps down by lowering the Vcore, you'll save a bit more money too in your electricity bill, and if you ever decide to push it further, you'll have that little bit more thermal headroom for a bigger OC.

i appreciate all the good info given and agree with you
all i can find as far as vcore voltage in asus probe 2 is in sensor section which reads 1.024v but no where to change it unless its labeled as something else as theres several voltage readings there.in cmos in aitweaker again several voltages there but no vcore.
once i get my fans and controller i plan on looking into things more.
i do need to reseal my thermal paste as i got a thermal probe pinched in it while sealing it but waiting till i get i get my fans first.
i wont be oc all the time,just want to tinker with it since its capable of doing it
is the vcore voltage listed below?

Well, before you do anything more with an OC, dial it back to stock, and familiarise yourself with the UEFI/BIOS, and try and avoid using windows based utilities if possible, they sometimes work, but they make too many assumptions about your hardware and what its actually capable of, and can push too much or too little voltage for the OC they apply.

But to explain your settings so that you understand what you're looking at.

The first option in Manual mode. BCLK, is the base clock, this setting should be left alone, it controls your PCI-E clock, RAM clock, and the iGPU clock and of course, the cpu clock, so ignore this and leave it at 100MHz.

The second option, CPU Voltage, is what I've been calling the Vcore, this is the CPU's internal voltage, and this is the setting we're most interested in atm, this setting dictates the OC you can achieve, a higher setting brings with it the ability to reach higher OC's, but brings with it higher temperatures and the risk of damage, so be careful with this one. DO NOT EXCEED 1.45V. I cannot stress this enough, any higher and you will destroy your CPU.

DDR voltage is your RAM voltage, typically this doesn't need to be changed, but if your RAM is rated for 1.65V then set this to the required level and leave it, check your RAM manufacturer for the correct voltage.

In the Advanced tab in the second picture, the VCCSA voltage does not need to be changed, and tbh, Asus should have left this one off the list, as it's a sensitive option that only the most extreme overclockers need, ignore and leave as is.

The CPU PLL voltage can be left at default, this does not need to be changed for the OC you require, and in fact, is very rarely changed even in the most extreme OC's, if you change this setting DO NOT EXCEED 1.9V.

The PCH voltage is what used to be known as the Southbridge, this controls your SATA ports and a few other things, usually you can leave this stock, but at overclocks about 4.5GHz or higher, you can up this slightly to get a more stable OC, I set mine at 1.15V, but you won't need that much so unless you're suffering stability issues, leave it as is. DO NOT EXCEED 1.2V. You will damage the southbridge if you do.

In the GPU boost tab leave everything stock unless you want to OC your Intel graphics, which I don't generally recommend as the GPU is sensitive to voltage changes and frequency changes. You can get a nice performance boost if you OC it, but if you're using a dedicated graphics card (AMD or Nvidia) then you have no need for this tab. I don't OC my iGPU, it's not worth the extra heat and power consumption, but if you do want to OC it, then we can look at that later.

So for the OC you want.

1. Leave the BCLK at 100MHz.

2. Set your CPU voltage around 1.15 to 1.220V more if unstable and DO NOT EXCEED 1.45V. Try and find the lowest stable voltage for your OC.

3.Unless your RAM needs more voltage or you're overclocking it, leave it at stock.

4. Set your Multiplier at 40 to set the CPU speed at 4GHz, same as 45 gives you 4.5GHz.

5.The VCCSA voltage needs to be left at default, same with CPU PLL.

6. Leave the PCH Voltage at default unless you're shooting for an OC of 4.5GHz or higher, and even then, only the smallest bump in volts is needed. DO NOT EXCEED 1.2V.

7.Leave your GPU at default unless you want to OC.

And that's it, but try and use the UEFI/BIOS instead of windows applications, Windows doesn't have the same hardware access the BIOS does, and this can cause problems and the assumptions made can destroy hardware, so try and get comfortable with your BIOS and what each setting does, the most important ones for you are the CPU Voltage and multiplier, you shouldn't need to change anything else.

Oh, and please do reapply your thermal paste, that could help your temps, use a small blob of thermal paste on the CPU, it should be about the size of half a grain of long grain rice or thereabouts, set the CPU cooler straight down onto the CPU and this will spread out the thermal paste for you, too much will actually increase temps, and too little doesn't fill the microscopic gaps between the CPU and heatsink. :)

i was looking at my case to map out how to locate my link commander when i noticed all this time ive been running without one of my h80 fans being hooked up-duh
so it got me curious to see what a load check would now be.
with the case fans on high and the h80 on low speed ,having my computer set at 4.4 ghz the cpu ran at 58c or 136f.much better than my other test at 4.3 ghz with temps in the 156f range
tomorrow the link goes in and ill be putting it to better tests
appreciate all the help from everyone

[Robinfox88]

LOL I had to laugh at that, but never mind, we all make mistakes, I made an even bigger one when I built my first PC, I put too much thermal paste (Arctic Silver 5) onto the CPU, and it squidged out onto the processor edge, where there's gold contacts (this was a core i5 750) and it shorted the CPU, it still worked once I cleaned it off, but you can imagine just how lucky I got xD

But those temps are sooo much better, and are actually pretty damn good. You could probably run the fans at medium and that'd still give acceptable temps :)

But looking at your voltages, if the VID (CPU Voltage) is being correctly reported then that's a little high, maybe you could try dropping it? You'll get even better temps if you do.

And do let us know how you get on with the Link Commander :) You're welcome btw, and enjoy your system :)

it appears 4.4 is my sweet spot as 4.5 crashes after a few minutes of prime load
but i do have 2 8gig ram chips and a different brand 4 gig chip installed so it may be a chip problem.
of course ill leave it at 4.2 most of the time as i like the very low 50's load temps
