If i were u i will push the CPU to the highest with max temp under 80c
use p95 26.6 to test on the CPU stability. This version is without AVX
Then use a 2-3 offset for the AVX
Dont bother too much on the AVX haha

BTW you better off asking those sifu s here
im still new on this 7700k oc
but what i experience is 7700k is very simple to oc
its the memory part that is headache hahaha

I'm encountering some prob also here. I'm very stable on 4133 c18. I try to tighten up all the timings n lower to c17. Hci tends to fail at the 200% mark for 3 days trying to play around with the voltage n sub timing still no luck. Any idea?

Are u sponsored? Can get so many CPU to try! Am trying to mess with rtl iol now to see if works

Gskill just announced 4333 kit also haha
Get n try it out when available

Bonus: DDR4-4400MHz 16GB (8GBx2)
As an extra bonus sneak-peek, the screenshot below shows DDR4-4400MHz being stress tested. The specifications are still under development, and would require some time to be ready for market production.

wow !
hahaha gonna order the 4500 when out woot!

gave up already hahah
saw a lot of ppl able to run 4133@1T with low voltage

i think we are having some weak imc

im like only 20% able to successfuly boot with 4266 

whats the best stable speed n timing u get on the ram?

First and foremost, I’d like to make clear that because your CPU hasn’t been tested to confirm the IMC’s capability of supporting 4266MHz, it’s likely the main reason why only XMP isn’t working.

However, I can help you through steps to find out how high of a memory frequency your CPU can support.

1.      To begin, please make sure that you go into BIOS and reset settings to optimal defaults. We need to make sure we start off from the most basic of settings, then apply setting changes to memory. It’d be good if you get into the habit of tweaking memory settings first, before making changes to the CPU, like the CPU frequency or CPU related voltages.

2.      Go into Ai Tweaker tab, and enable XMP. Then go down to the DRAM Frequency, and adjust it down to DDR4-3600MHz and change the DRAM Voltage to 1.350V. Save and exit. Can your system boot successfully into Windows at this speed?
a.      If your system can’t boot at 3600MHz, please let me know. The CPU’s IMC is likely very weak.

3.      If #2 was successful, go back into BIOS, change DRAM Frequency to DDR4-3866MHz. Can your system boot successfully into Windows at this speed?
a.      If DDR4-3866MHz was not successful, then you might want to check the CPU thermal paste to see if it’s dried. Or if your CPU cooling fan is screwed on too tightly or not evenly. Then try #2 again.

4.      If #3 was successful, go back into BIOS, change DRAM Frequency to DDR4-4000MHz. Can your system boot successfully into Windows at this speed?
a.      If 4000MHz was not successful, then 3866MHz is likely your processor’s limit. In this case, make sure XMP is enabled, then change the following settings:
                                                              i.      DRAM Frequency = 3866MHz
                                                            ii.      DRAM Voltage = 1.35V
                                                            iii.      CL Timing = 18-19-19-39
                                                          iv.      Command Rate = 2

5.      If #4 was successful, go back into BIOS, change DRAM Frequency to DDR4-4133MHz and change the DRAM Voltage to 1.40V. Can your system boot successfully into Windows at this speed?
a.      If 4133MHz was not successful, then 4000MHz is likely the processor’s limit. In this case, make sure XMP is enabled, then change the following settings:
                                                              i.      DRAM Frequency = 4000MHz
                                                            ii.      DRAM Voltage = 1.35V
                                                            iii.      CL Timing = 18-19-19-39
                                                          iv.      Command Rate = 2

6.      If #5 was successful at 4133MHz, change DRAM Frequency to DDR4-4266MHz with DRAM Voltage of 1.40V. If you are still getting error 55 or 49, hit a white “Retry” button just below the Reset button on the motherboard, and see if this helps booting into the system under XMP settings.


Kindly let me know how far you can go with the steps above. Please do note that XMP is enabled in all cases before manually changing BIOS memory settings.

that's d highest i can manage... temp aside limit wise it is almost there already...

ah_khoo | i3 6300 | 4.5GHz @ 1.39v | GIGABYTE Z170X-UD3-CF | Air (GeminII M4 LP)

novice level at best only bro... 

3600MHz on ram is a no go, should i pump more vdimm (than exisiting 1.35v)? looseen timing to 17-19-19 didnt help. vccio & vsa already @ 1.2v. 

waitin for d delid kit to pop d chip for lower temp... 

[attachmentid=8751802]

Finally got 4133c17 stable 1000% hci
High sa and vccio voltage has made it unstable previously
Lowered it down to 1.2 and 1.15 and everything passed with no errors

[attachmentid=8761464]

There u go the timings.
Best i could do at 1.4v for vdimm
1.15v vccio
1.2 sa
btw this is mode 1
mode 2 seems slower

Sifu,
Gonna get the following rig and start to OC by myself through the guides available online. Do I need to add anything to my build as I am going to place order preferably tonight.

i7 7700k
Asus Strix Z270G
Thermaltake Riing 3.0 240 Liquid Cooling
GTX1080 MSI Armor
PSU 650W G 80 Full Modular
M.2 SSD WD Blue 500GB
1TB WD Blue HDD
8GB RAM X 2 (Either Trident 3200 or 2600 normal one)

I supposed I have some few hundreds to spare is there any need to further improve it?

Hi Sifu's,

I am planning to over clock my i5 7600k. I got up to 4.6 @ 1.3v stable using the auto overclock feature on my Asus Z270F mobo. Temps was around 60-70 running on my AIO Corsair H100i v2.

Any tips or guide on doing the overclock manually? Im looking to get around 4.8 to 5.0. My biggest concern is what kind of temp I should look at and the max amount of power I should go to get those results. Thank you.

Hi Bro,

Thanks for the insight. I did try the pre-set for 5.0Ghz. The voltage was automatic as you said and it was set at 1.4v.

I was able to boot and used Aida64 to do a simple stress test. Temps was hovering around 70+celcius. However after pass 5 min into the test It went to blue screen. I did not have time to trouble shoot so I reverted back to standard config. But my guess it blue screen because of not enough voltage. So concluded that my chip may not be able to push at 5.0 in low voltage. That's why I want to do a manual over clock.

My question is, would it be blue screen even if the voltage are too high?

Guys, I am facing frequent BSOD in window 10 whenever I am trying to use the default preset at my MOBO to OC my rig a little. Most problem start when I launch a game.
My rig as below :
i7-7700k
Asus Z270E
Thermaltake Water Cooling 3.0 240L
G.Skill Trident 3200 8GB X 2

I have very minimal OC knowledge so I choose to just use the preset at my MOBO. I tried the XMP Profile to enable my 3200Mhz but I encounter BSOD during gaming. I also tried the 5gb OC preset and also encounter BSOD. Resetting to default setting seems to solve the problem.

Hey bro, tq for the reply.
The XMP Profile I just click the XMP Profile 1 (the only choice available at my Bios). Not sure of the setting but will look into it when I am home.
I realised that I am only able to choose either XMP or "5.0GHz OC preset" ? Will the 5.0GHz OC enable my RAM to run at 3200 Mhz?

will selecting 5.0Ghz OC preset after XMP profile reset the XMP Profile or both can work together?

Just now tried xmp then 5.0Ghz preset together with the voltage setting as shown in your screenshot but unable to in to window. Now I just used xmp with your voltage setting and can work smoothly already. Ltr will try on the 5.0Ghz preset again

Hi Guys,

Well here are my latest update over the weekend.

I am pretty pleased with the results. I am stable at 4.8Ghz with 1.35volts after 4 hours of stress test on Aida64 and 3 hours on intel extreme stress test. I am however facing issues with ROG stress test tool. The error I keep getting is "Luxmark is unresponding". I read somewhere that it is bugged.

The leading up to this results there are funny issues I faced. I did try the 5.0Ghz preset settings from asus but the voltage was set at 4.2volts which is too high for my taste. I tried bring the voltage down but anything below 4.2 would crash once I start Aida64. Even if I put 4.9Ghz at below 1.40v would crash.

What I find ironic is that even it is a 0.1 difference but the voltage increment is substantial.

Well as for temps @ 4.8Ghz I am hovering around 70-85 Degress on max load. It is below 80 degrees for most time during gaming.

I have a question. I am now using manual on my cpu volt/cache @ 1.35v. I plan to change it to adaptive. My stock volt is below 1.2v. So from what ive learnt is that 1.35v - 1.2v = +0.15v to be placed in the adaptive field. Can someone advise me on this? thank you.

Btw I will be uploading all my screen shots tonight.

Hi Sifus,

My rig is i7-6700K and Asus z170 Pro Gaming

I set my bios to 1.280 VID at 4300MHZ
I ran all bench mark and stress test and it passed good.
It is a mild overclock for my kind of rig...most would do 4500Mhz or even 5k with higher voltages.

My question is...everytime I boot up my computer
1 in 5 boot ups...it will not boot up and on AUTO will reBOOT(like pressing the restart button) and then 2nd time will boot up fine.
Only happens once every 5 times I switch on my computer, other 4 times is normal successful boot ups.

Is this ok? Or do I have to increase my voltage a little more for a stable boot up process. Like 100% success rate error free boot up...
