MX450 on HP Envy BA1561SA

[thealgo]

Recently puirchased the compact HP Envy 13 with I5 1135g7 and MX450.

In GPU-Z, it mentions that the max clocks are between 720-930mhz.  This would indicate that it has to be the LP variant of the MX450.

However on benchmarking, It can go up to 1515mhz when boosting.  Furthermore the benchmark results match that (and even exceed that of a 25w+ mx450 model

My assumption is that HP are using the LP variant but overclocking it via custom bios in the GPU?  If it really was a LP model, then it would not perform like a 25w model.     I cant really see the power consumption either as the charge rate indicator is not available to the system. However i can see on the two GPU rail power that they can get pretty high >17w, 24w on some occasions in total

Hence the question arises.  What MX450 model is on this particular laptop?

HI@thealgo, Welcome to the HP Support Community!

I reviewed your post and I understand that need help to overclock on HP Envy 13 notebook 

Let's start with performing a hard reset on the PC to release any excessive static/power that could have caused the issue  

• Turn off the computer. 
• Disconnect all external connected peripheral devices such as USB storage devices, external displays, and printers. 
• Unplug the AC adapter from the computer. 
• Press and hold down the Power button for about 15 seconds to drain any residual electrical charge from the capacitors that protect the memory. 
• Press the Power button to turn on the computer. 
• If a startup menu opens, use the arrow keys to select Start Windows Normally, and then press the Enter key. 

Second, you can check if there is a Bios update available for your PC, here is the link to download. 

Performing a test on the Hard drive as well as on the Memory from the Hardware diagnostics:  

1. Hold the power button for at least five seconds to turn off the computer.
2. Turn on the computer and immediately press Esc repeatedly, about once every second. When the menu appears, press the F2 key.
3. On the HP PC Hardware Diagnostics (UEFI) main menu, click System Tests.
4. Click Extensive Test.
5. Click Run once, or Loop until error.
   While the test is running, the time remaining and test results for each component are shown on the screen. The test can take 2 or more hours to complete.

   NOTE:

If the diagnostics are not available when using the F2 menu, run the HP PC Hardware Diagnostics from a USB drive. To download the latest version of the diagnostics, go to the HP Hardware Diagnostics website. For instructions, see Testing from an external USB device.

The best way to resolve the issue is by using the HP Guided Troubleshooter:

This is a joke right?   Is this response by HP done by a BOT as it sure seems so.  You did not even read my question.   Its better not to even respond compared to the template that you have posted as a response.

And furthermore, even if i wanted to overclock the device, that's certainly not the right way to do so.

No, I will NOT accept as solution

@thealgo,

I am sorry you happened to receive basic steps which would break the jargon in the process of issue isolation.

I will be glad to assist you with your query. Please elaborate on the same,

[thealgo]

Ok I will elaborate again.....

I Recently purchased the HP Envy 13 with I5 1135g7 and MX450.

The Reported GPU Clocks according to GPU-Z are between 720-930mhz.   (This clock speed is known to be the MX450 LP - Low Power variant)

However on benchmarking, It can go up to 1515mhz when boosting.  Furthermore the benchmark results match that (and even exceed that of a 25w+ mx450 model.  They are certainly higher than a MX450 that would be a LP - Low Power Model.

My Question is this....   What Model of MX450 is in this Laptop...  Is it a modified Low Power version of the MX450 with increased boost clocks, or is it the 25w Variant....

I cant really see the power consumption either as the charge rate indicator is not available to the system. However i can see on the two GPU rail power that they can get pretty high >17w, 24w on some occasions in total

Hence the question arises.  What MX450 model is on this particular laptop?    Please do not respond with instructions on how to Hard Reset or something that is totally non related to my question

Here are the options:

NVIDIA GeForce MX450 N18S-G5 GPU - Benchmarks and Specs - NotebookCheck.net Tech

Got to be one of the 25w versions. What is the specific model of the laptop? Have you tried getting the Device ID of the display adapter from Device Manager. HP sometimes is not very transparent as to the exact chips being delivered in its various models. 

[thealgo]

It is the HP Envy BA1561SA

GPU-Z Shows the below

https://www.dropbox.com/s/bs1qx2sxaadl4ve/gpu-z.jpg?dl=0 

This shows the 720mhz and 930mhz boost that indicates its a "LP" model

However on clicking the "lookup" button, it shows that its a 25w model

https://www.techpowerup.com/gpu-specs/geforce-mx450-25w.c3657 

with 720mhz and 930mhz boost that cannot be possible.   All 25w models have higher boost clocks

Device ID is showing as the following in device manager for the mx450.

https://www.dropbox.com/s/26my5gf9wu1pani/device-id.jpg?dl=0 

The device also clearly performs better than a LP MX450 and i have seen it on many occasions hitting 1550mhz or so.   According to the benchmarks on notebookcheck or so, i can see it performing usually higher than the median.

The main query is really if it is a modified "LP" version with custom nvidia bios by HP that allows higher boost clocks than its designed for or if it is somewhat a real 25w chip but gpu-z is getting the boost clocks wrong?

[Huffer]

DDR6 vram and 25w means it must be this one:

N18S-G5: GB2E-64 Package, 1395 - 1575 MHz, GDDR6 5001 MHz, 25 W

Boost is up to 1575, right? 

I can't speak for HP but I have been on this Forum for over 20 years answering questions. I can assure you HP is not overclocking anything on its laptops. If anything they tend to detune stuff because its being sold to all kinds of users and keeping everything running well within its limits holds down warranty expense. 

[thealgo]

According to GPU-Z and HWinfo, I have seen the Boost go up to 1550mhz or so.   However there is one interesting thing to note....

When using ASUS Boost 3 or MSI afterburner (As a test) to set the clock speed to 1200mhz ((Which should be in the range between its maximum) it resulted in a immediate crash.    This may be, i assume due to the actual values not overclocking but instead under-volting.

For example setting +150mhz extra, still results in max 1550mhz clock speeds however i notice the power profile curve in MSI afterburner is above the previous when upping +150mhz which indicates that its running higher clock speeds at lower voltages (Also tested power consumption on benchmarks and power consumption was reduced by 2w or so with no loss in performance.

Am i right in assuming that the GPU rail in Hwinfo is the ideal method of obtaining power usage of nvidia GPU?   At the moment, HWinfo does not show the discharge rate or system power draw for this laptop.   However sub 12w for nvidia GPU in Hwinfo is a common occurrence.  What is unusual though is that even at say 1400mhz at 98% load, the rail is showing 12w?   Wouldnt this be much higher at this frequency and load?   I have on some rate occasions seen it go higher than that (e.g 18-19w+ or so) There are two power rail's for nvidia gpu on hwinfo, but curious if both needs to be added together or if it averages out the power.

Memory overclock is really nice.  Can literally overclock to 6000mhz+  increasing bandwidth from 80gb/s to over 110gb/s

I cannot really comment on anything involving even a test overclock on the video. Jeopardizes your warranty. And we have about reached the limit of the information HP is going to provide to me (and indirectly, you) on the hardware it uses.
