Help Overclock ASUS P7P55D-E PRO, Intel Core i7-870 with good cooling fans - Page 2

You should change every timing, not just 9-9-9-24.
The other timings should also be coppied from xmp, if its left on auto it can be set to wrong numbers automatically

I have MSI p55-gd55 with intel i7 875k which is unlocked. I dont remember exact settings i used to get stable 4.0ghz, however temperatures where around 75c under heavy load, still it didnt crash in intel burn test or prime95. For cooling i have one Noctua NH-u14s double fan and nothing else.

Also my RAM is pretty similar CMX16GX3M4A1333C9:

I was using 1.65 since it was also tested voltage for this ram. I couldnt raise much vcore since temperatures go WAY up and blue screen or mobo started lowering vcore by itself.

I actually thought reason i cant get past 4.0ghz is motherboard too weak, but now i can see that you have similar problems, maybe try go with 1333mhz ram first?

A motherboard that is not the top chipset and with a decent overclocking vrm is a very good reason to stop overclocking, motherboards can be a massive limiting factor

If you want to do some ram though, which you may be able to get some oc with the ram.
Try my ram timing rules, or just overvoltage a bit and decreae the CL

I compared your asus motherboard to my msi :
https://www.msi.com/product/motherboard/P55GD55.html#hero-specification

Looks like its better suited for overclocking than mine, msi has also PRO version with lga1156 socket but i bought wrong one. Im using Noctua NT-H1 thermal paste which came with the heatsink and fan, are there anything better which brings temperature down substantially?

You would want watercooling, TEC or phase change.
Before that getting a good overclocking board is recomended

I dont want to invest yet to watercooling yet since my fan and heatsink is fairly new, what about thermal adhesives? Dont care about cpu getting glued to heatsink cause my next motherboard somewhere down the line will be different socket anyway with probably watercooling.

Someting like this?

Changing heat sink paste is not going to help,
Thermal adhesive is worse than paste

If the cpu is non soldered deliding will help, delid and stay delid.
Also lasp the CPU cooler

As mentioned before, 4.0ghz is a reasonable overclocking goal for 875k, but i wouldn't place bets on much more. You might get lucky.

Here's an observed power to core frequency curve for a particular sample. Notice how steep that curve is at 4.0. That's a tough wall to climb. My sample exhibited behavior just like this curve. 3.7 was easy as anything to reach, didn't even have to touch the voltage. 3.8 and 3.9 took some modest vcore bumpts to reach but not bad. To go from 3.9 to 4.0 though took a whole lot more voltage and made a whole lot more heat. I chose to run it at 3.9.

Hello again, and thanks for the support, it's much appreciated. :thumb:

 

I was a little busy yesterday, so I did not do anything, I ad no time. But I now underway and will try to tame Dram and ICM (VTT) to reach 4GHz. I have heard that people with my motherboard has managed to get to 4.0GHz, and a few have managed 4.4GHz. Hope this will be me. But I understand ram is some how important, and can be a factor that destroy this luck.

 

My question again when between 1333MHz RAM and 1600MHz RAM that I have. 1600MHz is xmp profile.

 

When ram is 1333MHz, then ICM is 1.1v and Dram 1.5v (1.55v). I understand that I can increase Dram volts a bit.

But when ram is set at the clocked frequency at 1600MHz, then it’s manual set to ICM 1.2v and Dram volts at 1.5v by xmp profile. Also, we have other things in dram timing control, but that’s alright, I fill all in.

 

I understand such that I can adjust the ICM as long I keep ICM no more than 0.5V below dram volts, and this is a rule I have to follow. If I go to use 1600MHz, how far can I go with ICM before it meets the same voltage as Dram volts? It had been nice to know when I adjust icm volts upwards from 1.2v, since I feel icm 1.2v is close to dram 1.5v.

 

I suppose 1.4v is max for ICM?

 

I have never done this before, but it's interesting.

We was talking about changing the dram timing control the manual way to use 1600MHz memory, an to use the xmp profile settings/number to enter them in manual. So I went over to the dram timing control. But there where a few settings i did not under stand what to do with.

 

-Ref Cycle Time is set to auto and show the number 107. If I try to set this number manual it's only number 100, 106 and 110 etc. No Number 107 to set on to manual.

 

-Back To Back Cas# Deley is set to 0 and in auto. If I try to set this manual, there is no number 0, it only start from 4, 5 and 6 etc.

 

-Round Trip Latency On CHA is set to 52 and in auto, but there is no 52 to choose from manual. It's, Advance from 1 to 15 clock. And Normal Deley 1 to 15 clock.

 

-Round Trip Latency On CHB is set to 54 and in auto, but there is no 54 to choose from manual. It's, Advance from 1 to 15 clock. And Normal Deley 1-15 clock.

 

So what do I do with this settings, just leave them on in auto?

 

The rest of the number I could enter manual with the right numbers...

 

I do not start with the 1600MHz before I hear from you about this. So I started with 1333MHz memory. I have reached 170 BLKC, then I got the blue screen first time. So I increased the ICM by 0.025 volt, and no blue screen yet. So it's kind of work this ICM changes, he he :typer: 

 

So I will now level up to 180 BLCK after I run prime95 for 5 minutes.
