i7 10700k sustained turbo boost clock

Hi everyone!

 

New here on the forum and this is my first post.

 

I just updated my gaming rig and got an i7 10700k coupled with an ASUS ROG STRIX Z490-F gaming MB (full list of my PC in my profile)

 

When I run the CPU at the standard clock and bios settings I can see that it boost to 5.1ghz on all the cores for few split seconds.

 

I would like to have 5.1ghz running constant on all cores so in the BIOS i disabled all limits [ASUS Multicore enhancement ENABLED - remove all limits] and [SVID behavior to AUTO] following the procedure that Linus showed here (minute 3:06):

If I do that however the clock is locked at 4.7Ghz on all cores and it doesn't turbo boost anymore. I know that the videos is about the 10900k but I wonder if the same concept applies to the 10700k.


My question is:

 

could it be that the PSU is unable to sustain the load and the CPU can't keep its turbo boost clock constant? 

I am still waiting to upgrade my PSU in preparation for a new GPU (RTX3090 whenever that'll be available for humans) so for now I'm running an old Corsair TX750W PSU.

Now, the MB has an additional CPU 4 pin power connector besides the standard 24+8 pin which I have not plugged in since my PSU is old and doesn't have an extra 4 pin cable. Could this be the reason why I can't keep 5.1 steady on all cores?

 

Cooling shouldn't be an issue. I have an arctic liquid freezer II 280mm in a push/pull config. With standard bios/clock: Blender classroom max temp 70°C. Prime95 small FTT for 10 minutes max temp 82*C.

 

I also tried to manually overclock the CPU when I had my previous Noctua NH-U12A unsuccessfully, then decided to upgrade to an AIO thinking the temperature where the cause but I still think the PSU is the variable which makes my overclock unstable, I will open a different 3d on the overclock

 

Thanks

Run hwinfo64 and look at the CPU limiting section, see what is actually going on. That might then give a clue how to get around it.

Thanks @porina

 

I'll have a look and report back

Max all core boost of the 10700k is 4.7GHz. 5.1GHz is only one or two cores (cant remember). Bade clock is 3.8, as long as it is above 3.8 it is turbo boosting

I had a look but can't see any values which have the "limited exceeded" set to [YES]. Was this what you were referring to? Sorry for the noob question but most of this is quite new to me.

Ok thanks! I guess it makes more sense now.

 

I can see it boosting to 5.1 on different cores but no all at once and not when running a load test on the CPU. Examples where I would see a spike to 5.1 is when loading a program and usually its just for a brief second or 2. This behavior however doesn't happen if I remove all limits from BIOS.

 

I guess to have it running at 5.1 all cores I would have to manually overclock it but here my doubt remains whether the PSU is the culprit of my unstable overclock? 

 

What I've tried so far:

I had a Noctua NH-U12A when I ran these tests, haven't tried yet with the AIO but temperatures were in check except for 1 run @5ghz which I aborted

 

4.8ghz overclock

[AVX instructions core negative offset to 0]

CPU Core ratio to Sync all cores

ALL-cores ratio limit 48

CPU SVID Support to DISABLED

CPU core/cache voltage to Manual

CPU core voltage override to 1.350

CPU VCCIO voltage to 1.200

CPU system agent voltage 1.200

CPU Load-line Calibration to LEVEL 4

 

Successful Cinebench R20

Prime95 Small FTT - after 30mins CPU L1 Cache error, it happened as the temp spiked for a split second from 90°C to 92°C but test kept running (I aborted after getting the error)

 

5.0 ghz overclock

[AVX instructions core negative offset to 0]

CPU Core ratio to Sync all cores

ALL-cores ratio limit 50

CPU SVID Support to DISABLED

CPU core/cache voltage to Manual

CPU core voltage override to 1.350 and all the way up to 1.400 which I was uncomfortable to increase so much 

CPU VCCIO voltage to 1.200

CPU system agent voltage 1.200

CPU Load-line Calibration to LEVEL 4

 

Successful Cinebench R20 (only at higher voltages)

Prime95 Small FTT instant freeze (managed to get it started for few minutes when I upped the voltage, once it reached 95°C and I aborted, second time it froze)

 

5.1 ghz overclock

[AVX instructions core negative offset to 0]

CPU Core ratio to Sync all cores

ALL-cores ratio limit 51

CPU SVID Support to DISABLED

CPU core/cache voltage to Manual

CPU core voltage override to 1.350 and all the way up to 1.400 which I was uncomfortable to increase so much 

CPU VCCIO voltage to 1.200

CPU system agent voltage 1.200

CPU Load-line Calibration to LEVEL 4

 

Cinebench R20 instant freeze 

Prime95 Small FTT instant freeze

1- No, 750 is more than enough.

 

2- NO, is ok with 8.

 

You won´t hit 5.1 on all cores, just in one core.

All core for this i7 is 4.7, if you want 5.1 Ghz all core you have to overclock.

Thank you! 

 

I am learning on how to tune in an overclock on this i7, I knew some basics but there's so much more. 

 

For example I think the voltages I was feeding were way too low to sustain 5.1Ghz all cores under load... on the BIOS the AI overclock prediction was actually over 1.56v non AVX and 1.63 AVX which in my mind is super high, but I guess that these 10th gen CPU are that power hungry.. I'll run some test to see how the temperatures are doing 

 

What kind of voltages/temps are you seeing? I noticed you've got yours running at 5.125Ghz

 

Found this video which goes really in depth on explaining some of the basics (many of which I didn't fully understand until now). It's especially useful for me as it uses the same BIOS as I have and although is a Z390 platform I think it's still relevant.

 

It's long, but worth it in case someone is looking for some more info

nice! quite some toasty temps you've got there.

 

What kind of voltage/overclock settings did you use?

im not gaming. so i dont really care about temps since i dont think i will ever reach those temps without cinebench. im developer so ...
i used intel performance maximizer 

but somehow i got to 5.1

EDIT: plus the fans are set to "SMART" which as i understand is : kick of if u want to :P

EDIT2: i use this crappy cooler CAPTAIN 240EX WHITE GAMER STORM CPU LIQUID COOLER

My current settings are:


    CPU ratio: all core.
    CPU ratio: 51
    CPU ratio mode: Fixed mode.
    Voltages override.
    Ring ratio 48.
    CPU core voltage: 1.32.
    CPU loadline calibration control: Mode 3
    Stock XMP profile 4000  16-16-16-34
    Bus clock 100.5 Mhz.

 

But these voltages wont be the same for you, you have to go up 0,5 and test until fully stable behavior.

Temps are good on games (below 60) on sintehitc test they are around 90-95 with corsair h100i proxt 240mm.

Thanks for the screenshot! It gives me lots of good info to compare my system 😃 appreciate it!

Thanks @EspinalAndres!

Yes I know that just copying the settings for an overclock is a big no-no however it's nice to see what other people are getting just for comparison 😃

 

5.1Ghz @ 1.32v I'd say it's pretty good!
