[SOLVED] CPU not reaching Clock Speed

[SpawnofAngel]

Hello. I have an i7-9700f @ 3.0 Ghz but it is stuck at 2.79 Ghz. I've checked power plan settings, updated BIOS, reset CMOS, Updated all drivers(several times), everything i can <<Edited by moderator>> think of. Turned intel boost off and back on, changed the power plan of the BIOS itself. Turned XMP on(it was off). This is all new hardware as well. Less than a month old. It works "okay" but for the specs i have it should be performing much better than it is.
Every benchmark, stress test ive run including Cinebench, OCCT, prime95, etc. I'm seeing my cpu sit in the low 40s and ive never seen it about 60. My GPU sits around 50 as well

What is the make/model of your motherboard? What are the specs for the rest of your system, as well?

 

[SpawnofAngel]

I7-9700f @ 3.0 Ghz ; Turbo @ 4.7 Ghz
2070S
ROG Strix Z390-e gaming
16 gig DDR4 @2666 Mhz
Samsung 970 evo (500 gb)
Barracuda seagate HDD (2 Tb)

Just to confirm, do you have the 1502 version of the BIOS installed?

Also, have to made any manual setting changes to the CPU settings in your BIOS?

 

[SpawnofAngel]

Yes. Just double checked and BIOS is 1502 and all my cpu settings are default

 

[COLGeek]

What application are you using to measure the processor's speed?

If you don't have CPU-Z installed, install it and see what it reports.

[SpawnofAngel]

I use CPU-Z, NZXT, and Double checking with Task manager.

I use CPU-Z, NZXT, and Double checking with Task manager.

Do they all properly identify the CPU itself?

 

[SpawnofAngel]

Yes they do.

 

[COLGeek]

Are you using the stock Intel heatsink or an aftermarket model?

Does your BIOS identify the CPU speed as previously mentioned (2.79Ghz), like on page 3-7 of the mobo manual?

I am using the NH-U12A premium cooler and the BIOS reads at 3.0 Ghz (30x ratio and 100 Mhz BCLK). However CPU-Z is reading it at a 28x multiplier ratio with the correct variable 8 to 47 ratio that intel boost should have available.

 

[COLGeek]

Okay, that is progress. Seems BIOS is reading correctly, but that Windows is reporting something else. Have you been trying to use XTU or AfterBurner to OC anything?

 

[SpawnofAngel]

I have MSI Afterburner installed but I have not tried to OC anything yet.

 

[COLGeek]

When you built this system (with your current CPU), did you recycle a previous installation of Windows, or did you perform a full, clean install?

 

[SpawnofAngel]

Clean install. Tried to make sure everything was up to date as possible

 

[COLGeek]

Is Windows up to date? Also, did you install the motherboard chipset drivers, either from Intel directly or from Asus?

 

[SpawnofAngel]

Windows is update to date on all drivers and I used intel driver assistant to get all my drivers in. I just double checked that I had the chipset specifically and with the IDA program and its all up to date.

 

[COLGeek]

This is certainly a baffling issue. BIOS sees base speed as 3.00Ghz and Windows (and apps) report as 2.79Ghz. Do you have XTU installed?

Set multi core enhancement enabled or on in bios and check ur power plan in windows.

 

[SpawnofAngel]

I installed XTU like 2-3 days ago to see what it could do but i was looking through intel's info page about it and found that the 9700f isn't a valid CPU for it so i haven't done anything with it. Also, I did just set multicore enhancement on, though it was on auto before.

 

[AngelJin]

What about windows power plan ?

 

[SpawnofAngel]

Yep. One of the first things i did

 

[AngelJin]

The only other think is that ur psu dont give enough juice to ur system since ur temps are ok.

 

[SpawnofAngel]

I have figured it out! It was in the power plan settings. While i was snooping i found that the minimum processor state was set to 85% and that <<Edited by moderator>> with the speed. for some reason it wouldn't allow turbo to take it anywhere even though the maximum processor state was still 100%. Though I dont notice a large difference in the frames im getting

My PSU is the Corsair 850x so it should have plenty of breathing room on power

 

[SpawnofAngel]

Running a benchmark, I only saw an improvement of ~20 percentile. and in game i got about a 15-20 frame boost. still well under what i should be getting at around 90 fps
