Clock Speed Selection

[JohnP100]

My HP Envy has a Core-i9 CPU and was advertised on Amazon with a clock speed of 5.4Ghz but it is only running at 3Ghz. I cannot find a way to up the speed. There is no option in the BIOS to set the clock speed.

How do I get the advertised clock speed?

@JohnP100,

Welcome to our HP user Forum!

Just stick with me for a minute.

Your HP ENVY Desktop PC TPE02-1000i (6L729AV), according to: https://partsurfer.hp.com/partsurfer/?searchtext=7Z6F0AA&searchby=product, is supposed to be fitted with an i7-13700, LGA 1700 Processor.

Apparently upgraded to an i9-13900K -please confirm.

Upgrades are wonderful, but there is a caveat.

Assuming that you got an i9-13900K instead, looking at Intel's i9-13900K specs here: https://www.intel.com/content/www/us/en/products/sku/230496/intel-core-i913900k-processor-36m-cache-..., achieving the 5.40 GHz processor speed, is, well, conditional -and I quote: "The frequency gain and duration is dependent on the workload, capabilities of the processor and the processor cooling solution."

In addition, the i9-13900K's nominal speed is listed as: "Performance-core Base Frequency: 3.00 GHz", and: "Efficient-core Base Frequency: 2.20 GHz".

The i9-13900K's TDP (aka "Processor Base Power") is listed at 125 watt.  But (there always is), in order to reach the blistering 5.40 GHz "Maximum Turbo Power" speed, this processor has to draw an eye-watering 253 watts...

(In contrast, an i7-13700 has a "Processor Base Power" rating of just 65 watt and a "Maximum Turbo Power" draw of 219 watt.)

That presents a problem, you see, because according to the aforementioned HP part surfer link, your desktop was fitted with an HP-branded 500-watt Cooler Master G500 Gold power supply (p/n: M98828-001) -unless that was upgraded as well: please confirm.  Point being, seems doubtful that a 500-watt power supply can provide this kind of juice AND power the rest of your rig without causing all manner of power throttling issues.

And that is what I think is happening: your i9-13900K is happily coasting along at 3.00 GHz because it is power starved, and possibly because it is getting (too) hot.

[EDIT:] And the more I think about it, the more I am inclined to believe that a CPU heatsink upgrade may be necessary, especially if you haven't got a liquid AIO cooler.

Hope this was helpful.

Kind Regards,

Thanks for your quick response NonSequitur777.

The product I purchased is this: Amazon.com: HP Envy Desktop PC 4TB SSD 128GB RAM Extreme Win 11 PRO (Intel Core 13th Generation i9-1...

As you will see, it says 5.8Ghz and the detail description talks about a turbo boost of 5.8Mhz.

I have now installed a BIOS update, which includes a diagnostic section that is displaying a clock speed of 5445Mhz (and a Maximum of 8800Mhz). The HP PC Hardware Diagnostic software is now showing a clock speed to match the BIOS. However, the Windows System details still shows the speed as 3.00 Ghz. I am inclidened to believe the BIOS and hardware diagnostic.

The older Omen I have had the ability to tune the Clock speed and there is an implication here, that the speed can go higher. However, there does not seem to be a tool to make any adjustments.

As you will see, besides the graphics card, the spec is much higher than a new Omen 45L, that is why I selectd it. I have to assume that if the displayed specifications are valid, the vendor has made the necessary power upgrades to support this configuration.

I am happy that the speed is now showing the standard 5445Mhz, but I would like a tool to enable me to adjust it as needed – perhaps it would even let me reach the specified 5.8Ghz.

@JohnP100,

That is a very nice PC!

Just out of morbid curiosity, do you mind checking out the wattage/part number of your power supply?

And what graphics card did it come with?  All it says is "Nvidia GeForce RTX" without specifying what model RTX.  For the three Grand you spend, it better came with an RTX 4070 Ti or 4080...

There is no external indication of what the PSU rating is. I would need to open it up, which I prefer not to do at this time.

Unfortunately, the card is only a 3060, but I did not pay the current price. It was $200 less than that and I used reward points, so that I only paid about $2000. A 4070 would have been nice and I would have paid the additional $300 for it, if it was available, but I suspect it would have required an even more powerful PSU.

@JohnP100,

Well, looks like you are all set -congrats with the new desktop!
