i7-7700 non-K is not hitting 4.2GHz

RodoGodo19 · May 13, 2017

CPU: i7-7700
Motherboard: asrock h270m-itx/ac

The CPU is not hitting 4.2GHz while playing heavy games, it runs at 4.0GHz, why?.
I didn't touch the BIOS...

Help?.

4.2 is maximum single core frequency at which the processor is capable of operating using Intel® Turbo Boost Technology. On all four cores you will have a max of 4GHz

CAPSLOCKSTUCK · May 13, 2017

In "power options" try High performance

I ran CineBench Single Core and the CPU doesn't pass 4.0GHz

what is wrong?.
I have Turbo Boost enabled in BIOS, I checked that...

Crap Daddy · May 13, 2017

I don't see any reason why it shouldn't turbo to advertised values. If you right click in cpuz on core speed it will show you in real time the speed on all 4 cores. Or you can download hwinfo which I find good.

Cinebench is multicore bench, it not gonna boost to 4.2GHz.
Try CPUz single core bench test.

Run the CPU-Z benchmark.

Tomgang · May 13, 2017

Intel turbo boost needs certain things to be with in spec before it boost to its max. First of all max TDP must not be exceeded and a given temperature as well.
Your cores gets above 70 C and one at 78 C and that is high i my opinion.

In your screenshot even then you run single core bench there are load on more than one core/thread and that will not give you that 4.2 GHz boost clock. Only one core even maybe one thread before you will se the max boost.

try cpu-z benchmark or a stress test program like Prime95 and set to stress only one core and one thread.

alucasa · May 13, 2017

80c shouldn't an issue. That's still 20c from Tfunction.

I've had i7-4770 run in low 90cs for years no problem.

I did it, I ran single core benchmark and the results are the same, 4.0GHz always

alucasa · May 13, 2017

Well, I don't see a huge deal here but if you dislike what you are seeing, return the chip.

peche · May 13, 2017

get HWinfo, run sensors only... then ...Run valleybench which is free and decent for some tests....
then let us know....

the tempts on all four cores being about the same suggest to me that all four cores are working not just one.. if only one core was working hard the temps on the other three would be much lower..

what i am saying is you may think you are just running one core but you are running all four.. hence the cpu speed being only 4 gig

Update your bios

NdMk2o1o · May 13, 2017

Can you set the multiplier in the bios to 42? and afaik 4.2ghz is the max boost on a single core, not all so you likely wont see it in games that are multithreaded, strange it doesn't boost up to that on a single core when stressed though

Most H270 chipset boards u can't control the multiplier on plus it's a non "K" sku cpu.

I know it's non "K" but you can still run the highest multiplier on all cores on all non-K chips... that is of course if the motherboard allows it in this case it seems it doesn't which kinda sucks...

NdMk2o1o · May 13, 2017

Don't normally double post so apologies, first newegg review states this:

P state values are incorrect for 7600k turbo boost. It would top out at 4.0 ghz instead of the CPUs 4.2 ghz stock value. I emailed ASRock technical support about this issue and got this response:

Try set up below BIOS setting in OC Tweaker > CPU configuration.
1. Long Duration Power Limit: 4095
2. Long Duration Maintained: 128
3. Short Duration Power Limit: 4095
4. CPU core current limit: 255.5

Test with Prime95 to load CPU 100%.
Check with CPU-Z for multiplier.

Seems to be a board issue not the processor, to the OP I would look into the suggestion from Asrock see if that addresses your issue, ok this is a different chip and an "K" one but I think this is the same issue as the OP is describing on his 7700, worth a look into.

Guys.

My CPU is a non-K model and my motherboard is a H model, I can not overclock the CPU.
The BIOS is updated.
Turbo boost is enabled.
I ran CineBench Single Core and the CPU doesn't pass 4.0GHz, sadly.

I will try the steps in the BIOS to see if the CPU can get up to 4.2GHz.
I had an ASUS H270 ATX motherboard last week and the CPU was working perfectly. This seems to be a motherboard issue or BIOS issue.

As I said doesn't make a difference, if you had the option to change multi in the bios you could set all 4 cores to 42 and in effect overclock it... however as has been pointed out that's not an option on your board so it's kind of a moot point anyway.

it's describing the same scenario/issue you have so I'm guessing that would be your best bet, it might have however been fixed with a bios update are you running the latest bios for the board? EDIT: sorry missed the bit you said it has the latest bios, my bad!! let me know how you get on with those steps then :toast:

I tried and nothing happened.
The CPU kept 4.0GHz no matter what.
and yeah I'm running the latest bios update.

Maybe raise a support ticket with ASrock, definitely seems to be a board issue, and if you can't "fix" it, it's not really the worst problem in the world as you're only missing out on that 200mhz on a single core load :oops:

^^^^This.
All four cores are working, not just one.
Even your Cinebench run shows you using 4 cores, not one as you think.
This appears to be user error.
Can you boot in to the BIOS and set just one core to run?

I know my HTPC is a damn lot older, but I didn't have any problems with H61/2500K putting all cores at max multiplier.

And I'd try SuperPI since if something is a single core benchmark, that's one of those.

I tried my CPU with an Asus Z270 ATX motherboard and the CPU is hitting 4.2GHz perfectly.
It seems that my ASrock motherboard is having difficulties even having the latest BIOS update.
I opened a support ticket with ASRock.
