Help Overclock ASUS P7P55D-E PRO, Intel Core i7-870 with good cooling fans

post #1 of 111
Thread Starter 

Hi, I wonder if someone want to help me with this. First time clocker, and clocked a little easy on this computer, first time. Managed to get from 2900MHz to 3800MHz the easy way. I want to max this out, break a record or something without breaking my computer, and maybe learn something or two.
I wish to reach more than 4000MHz, maybe 4400MHz, or as high as I can get it. Cooling is not the problem here.

 

My cooler is great Noctua NH-D15S dual fans. I have also two other Noctua fans in the case, one 120 cm in rear, and one 140cm at bottom. I get at stable 50 Celsius in OCCT and Prime95 when in 2900MHz. When in 3800MHz I get 60 Celsius, stable. The Intels stock fan on top as comparison and fun. So this Noctua is a cooler beast, I'm very satisfied with it. When starting up, I get low 350 rpm on the fan, so it is also very quiet. With the stock fan I reached 98 Celsius in OCCT when even that I was not clocked. So I had to purchas a new fan, King Noctua it was.

Specs on computer: ASUS P7P55D-E PRO, socket 1156, Intel Core i7-870 2,93GHz, and MSI Nvidia GTX 970 Gaming 4G. And 16GB Ram.

 

 

This is my two picture under is from my original bios settings:

 

 

 

Under I is my clocked version of bios:

 

 

 

What I think is so difficult is this special ram I have: Corsair Vengeance DDR3 1600MHz 16GB CL9, Kit w/4x 4GB XMS3 modules, CL9-9-9-24, 1.5V, Low Vengeance Heatspreader.

They come in 4 modules, 4GB each, link under.

 

http://www.corsair.com/en/vengeance-16gb-dual-channel-ddr3-memory-kit-cmz16gx3m4a1600c9

 

As you see they change the IMC volt to yellow And Dram volt in a way I don't understand, they are in the clocked version of the picture set to xmp, but I managed to clock the CPU to 3840MHz. But I have had a two of NML_Hardware_Failure two time split between on several days. Maybe it was a error with Nvidia driver it self, so I reinstalled it. I had some blue screens when trying, so something can have happened then. Never touched the volt in this tries.

 

So are there some friendly soul here that would help me reach my goal?

If your cpu is unlocked, All you need to do now, is just overvoltage further and keep temps below 74C maximum in either core or socket.
Otherwize, clock higher with fsb

If you can't reach your desire oc running prime stable, then you will need to delid the cpu, If it is non soldered.
If its soldered, then you want to get water cooling .

Sanding your cpu block on a flat surface, such as a non scratched piece of glass will make it flat, give better heat trasnfer and hopefully higher oc.
Put the sand paper on glass table, tape it and sand

CPU ratio settings on 24 is max. Heat is not a problem at all. On 3800MHz in OCCT and Prime95 I have stable 50 Celsius all the way… Even played some games etc with it. That is good numbers for the cooling.

 

Ok, so fsb, you mean then raising the BCLK Frequency that as is now on 160 in xmp profile? I have a ram that go in an overclock mode to max 1600MHz, it's therefor it is been selected to xmp profile, so it could adjust the volt by it self for the ram, as you see on the last picture. So I can’t touch BCLK anymore without raising the ram over the overclock limits. The ram limits max is 1600Mhz in xmp profile.

 

I can do two things then. Lower the memory MHz when in xmp profile, so that I can turn BCLK up farther, and I can go far much over 4000MHz if I want. But then I also go into blue screens, and not even load into the windows. I think this is because of the volt, I need to adjust the volt. But to what?

 

Or I can turn xmp profile off and use manual or oc profile (you see them at top of the picture), but then the imc (VTT) and dram volt as shown in the last picture, will be set to on auto, the number will be different. I can then turn the memory MHz all down, all the way to the lowest point, and then adjust CPU ratio and BCLK up. I can then go way up over over 4000MHz if I want.

 

I then get blue screen on both methods. Think it’s because of the wrong volt, that its automatic set on to auto. I have not touched it? What should I set in on? That’s my problem, and I don’t want to set on wrong volt either, fry my computer or something. I don’t know the limits for the volt.

 

What I think about, is setting profile to manual profile. Adjust the memory all the way down. Then raise cpu ratio down to etc 12 and begin to raise the bclk.

 

In that proses I need to voltage, change the volt. Because everything will at start be automatic set to auto, and I meet the blue screen or not load to windows at all.

Thats right, now, to hit your 4+GHZ target. You need to increace blck.
Make sure ram freq stays at stock or known stable settings.
Make sure northbridge frequency also stays at or below known stable settings.

This is ddr3 right? DRam voltage should be 1.65V or 1.7V. Some rams require using the turbo voltage to run stable at stock speeds.
For DDR4 it seems to be 1.3-1.4V for the turbo voltage
Coppy your ram timings on the xpm profile. Manually set it, or set your known stable timings.
Now set it to 1333 or 800MHZ then try booting.

(other than CPU and ram voltage. Everything else should be set on auto or stock settings)
touching other voltages not going to help with stability. If you want more uncore freq/nb oc then increace cpu nb voltage and motherboard nb voltage.
Increacing any othervoltage than this, will risk destorying your motherboard or cpu.

For imc voltage they say it can help bclock overclock.
http://www.masterslair.com/vcore-vtt-dram-pll-pch-voltages-explained-core-i7-i5-i3

Run prime 95 to check for cpu stability and run memtest to check for ram stability.
For mem test, open multiple coppies to stress more than 2GB of ram. Each coppy of mem test running occupies a core.

For longer lifespan, if you desire it, keeping the cpu under 60Degrees is good and ideal

http://hcidesign.com/memtest/
Donload the free version of mem test

For higher bclock, setting timing to 2T or 3T can help getting higher bclock oc.
Setting the timing to 300 or 350 or 400NS will also help
This is for ram timings

You should disable speedtech, turbo mode tech, leave extreme power phase on auto and disable cpu level up

If your woundering if you motherboard is handling the workload ok, then touch the VRM and NB heat sink and southbridge heat sink. If it is burning your hand, that means you want to put a fan directly blowing air onto it

Ok, I will try that now, and report back.

 

It is this ram I have, it's a DDR3 ram, Voltage 1.5, speed 1600MHz in XMP profile. It's a already overclocked ready ram, if set to xmp profile. So in xmp profile, the volt is automatic adjusted to manual ICM 1.20000 and Dram is set then set to 1.50000, as you see in the last picture. I suppose I would just have ICM and Dram at this oc/xmp settings. I have heard people get this cpu up to 4.4Ghz.

 

This is the ram and give a overview of the specs for the ram. I use, 4 module of this, that give me totally 16GB.
http://www.corsair.com/en/vengeance-16gb-dual-channel-ddr3-memory-kit-cmz16gx3m4a1600c9

post #6 of 111
Then you should set ICM to 1.2V manually, and you can also set your ram at 1.65V which may help stabilty 1.65V once your overclocking.
Again, to see if your ram is doing ok touch the heat sink and if it burns your hand. Then its too much voltage

Also set your timings to the same as XMP profile manually, this is very improtant

If you can't get 4.4GHZ then the cpu is not a good overclocker, so to go higher, more voltage and better cooling will be reqired.
Also if your motherboard isn't the best chipset with decent overclocking VRMS, then your motherboard may be holding you back from the 4.4GHZ

If you don't belive me on those unessercary voltages, then you can increace them a bit and clock for cpu or ram 10-20MHZ higher, if it dosen't clock higher then back down to stock votlages

I used to run an 875k at about 3.9ghz and with 1600 speed ram. It started taking too much voltage and getting too hot for me to run it any faster. I'm not so sure 4.4 is a nominal target that you should expect to be able reach with these chips, 4.0 is more approachable. If you have a good sample you can go higher, but you can't really bank on that. This guide was pretty good.

http://www.masterslair.com/how-to-overclock-intel-core-i7-i5-i3-cpu-overclocking-guide

Sounds like your cooler does a great job!









I ended up running it with a blck of 156 and somewhat higher vcore than in the screenshot. I wanted to run it an a nice round 160 for a nice round 4.0ghz, but the voltage unload p95 load needed to be too far over 1.3 for my taste and it ran too hot for my tastes too.

Yea, the cooler is the coolest. I am very satisfied michael-ocn. I can really recommend this cooler, and it's so quiet, 350 rpm on idle. I received a cpu fan error after I put the fan in. I was shocked and fearful. But then I realized later that my computer did not realize that I had thrown out the stock fan. Bios has minimum rpm of 600 then it warn you, so when it then get a fan who has only 350 rpm, then the bios get a bit confused, so it warns you. So you have to change this limit in bios or disable it. But a was in chock, and it was so quiet, that I had to open the side panel to see if the fan was moving, and it was, and it was also a good temp. So from chock ohno-smiley02.gif, to be very pleased :drum:

 

But Iwamotto Tetsuz I have a plan.

 

What if we isolate the memory and and cpu from limiting BLCK? I understand it is so that the memory and cpu can limit the BLCK limits.

First change the DRAM Frequency to the lowest.

Next take care of the cpu, by lowering the cpu ratio to 12 (or is this to low for me?), so it will not affecting BLCK. So it will then be way under it's original GHz specs.

Then lower the QPI frequency to the lowest, since this also can limit overclocking the BLCK as I understand it.

 

Then go to VTT (IMC) change this to 1.1, since I have a memory at a volt under 1.65. Mine is 1.50-1.55.

Then raise BCLK from 133 to 150, then boot in to windows run prime95 for 5 minutes. If error, raise VTT by 0.025v at a time. And repeat the prime 95 test, until stable. Once stable, raise the BLCK by 10.

Increase it by 10, or raise VTT 0.025 etc until I hit the desire BCLK, or hit the max VTT I'm willing to try, or hitting Intels max VTT.

 

You see the picture, if it fails, or I fail to hit max BCLK, start lower BCLK again etc until if I hit the wall of max BCLK. 

 

I was then thinking about doing the same thing again, but with the vcore volt. Raising the BCLK from 150 and up, and raise vcore by 0.025 from standard vcore volt, and/or raise BLCK by 10 to I reach max BLCK again, or then lower it again.

 

I have heard that once I reach 180-200 BCLK I maybe need to raise the PLL to get the system stable, and most people never raise it over 1.9v as I heard. Default value is 1.8v, I think.

 

So now, "when" I find a stable BLCK I can raise the memory multiplier, and maybe reach over 4Ghz.

 

What do you think?

 

One question about this. My memory is basic a 1333MHz module, but support xmp (extreme memory profile), so when this is turned on, it's basic a 1600MHz memory.

 

My question is. Do I start this quest with xmp, 1600MHz, then lower the DRAM Frequency to the lowest. If so on xmp 1600MHz VTT is already at 1.2v as standard, and dram at 1.5. And then start raising VTT from 1.2 and up. Or just start out with basic 1333Mhz to isolate and find my max BCLK?

 

I heard that this mboard/cpu is more suited for 1333MHz memory modules....

That would be helfull keep both ram and cpu understock speeds and boost for maximum bclock
I'd recomend starting from stock voltages for the blck overclock.

Setting XMP or manually setting timings and voltage is the same thing


Vcore is only going to help you get more cpu GHZ, not going to help blck at all

Start this quest with XMP voltages, then manually set xmp timings then oc your bclk

When you say manually set xmp timing. Do you mean all the changed DRAM Timing Control numbers. Or just the first few numbers etc; 9-9-9-24 as this. Because I notice when I activate xmp profile, I see many other numbers down in this lists is changed, not only 9-9-9-24.

 

I will continue tomorrow, it's late. But one thing is for sure. It's funny to be at 18Ghz when your original speed is 2,93Ghz. But just for trying, nothing else :). You kind of get the feeling of what the cpu Ghz on own computer have to say for performance. Not as much as you can feel it when you change gpu to some better, and in game performance etc. But you can feel it. It has it's effects upsidedwnsmiley.gif
