What kind of CPU part I could use for my HP Pavilion dv6-6c29tx laptop upgrade?

[jarkky]

Can I use i7-3940XM for this laptop upgrade? Is there risk for overheating the laptop with this 55W power?

Do I need different BIOS version if I want use i7-3940XM?

This could probably drain the laptop battery very fast.

New HP ENVY 17 with i7-10510u could be better choice for battery operation time.

I didn't see HP ENVY 17 with i7-10710u available. Is this coming soon?

What are the possible CPU models compatible for the Pavilion dv6 laptop?

Any ideas if the service center could change the part once I have received it?

Anyone here selling this part?

Hi @jarkky

Welcome to the HP Support Community. 

Refer to page# 1 and 2 from the Service Guide for compatible processors.  

For part# and installation instructions, refer to page# 87 to 90 of the Service Guide. 

You may take your computer to a local PC repair store, they should be able to help you with the upgrade. 

HP does not recommend upgrading or downgrading hardware parts or software that is bundled with the product as It may affect the manufacturer's warranty and performance, however, you could change the configuration at your own discretion.

Hope this helps! Keep me posted.

Thanks!

I checked this manual and I will try the CPU-upgrade soon.

What about SSD-support? The service manual mentions only 160Gb maximum size SSD.

Do you think I could use Kingston 480Gb SSD here with the SATA-III -interface?

Also it was checked that 8Gb of memory failed to work in this Pavilion laptop.

I could install only maximum of 4Gb.

Hi @jarkky

Thanks for replying. The parts mentioned in the User Guide are tested with your computer.

That case the laptop 2012 model has no more warranty left.

It is quite old so it could suffer some failure but I try check if it has any upgrade options left.

This part as mentioned at the service guide page 1 seems to work:

Intel® Core® i7-2860QM 2.50-GHz (SC turbo up to 3.60-GHz) processor (1600-MHz FSB, 8.0-MB L3 cache, dual core, 45 W)

The upgrade seems successful with temperature issuse detected. To change the part I used the local laptop service... It took some time and effort to change the CPU because almost all things had to be open before the part was possible to be changed.

It looks something is not good in Windows performance though:

The upgrade follows the below guideline:

But possibly the temperature of the CPU is too high at 54C:

It is possible though that if I have the right part, but that the thermal grease used is not good enough or the CPU screws was not tightened properly...

It is possible that I got thermal past with low quality or expired thermal paste as some thermal pastes have shelf life of 2 years only.

The HP laptop cooling solution... Can in that be improved somehow?

Maybe if some other cooling parts could be installed there.

As the problem can be in the installation or thermal paste itself it can be not easily determined and I have no means

to inspect the thermal paste itself and it was used.

The thermal paste came in a paper sack with the CPU itself so it is hard to know what brand it was or if it was expired the

shelf life.

The Idle temperature in the Windows10 looks slightly higher than for Linux case:

However main issue is probably the temperature during multicore operation:

If the laptop internal cooling is not enough, then I don't know how to improve it. We can try first replace the given thermal

paste with something else that might work better... Also if 3.6GHz operate with lower supply voltage then not sure

if OS or BIOS could find the setting and do it for me.

So I will add latest results I got with the Windows10:

Here it can be seen that the maximum temperature was 94C during the multicore loading and this is more than the

Intel safety limit of 85C.

So I guess I should still try check the thermal paste. Supply voltage settings is something I can not do and it might be

heating less at lower supply, but then also might suffer of lower maximum clock speed.

Thank you for posting on the HP Support Community.

I would request you to reach out to our Support and our Support Engineers should be able to check the available service options in order to diagnose the computer physically. HP Support can be reached by clicking on the following link:  www.hp.com/contacthp/​​​​​​​

They suggest visiting service center and checking the cooling fan.

Let me see the results again after visiting the service center.

The fan seems to be good at this moment and changing the "thermal paste" into Arctic-4 seemed to help reduce the CPU temperature more than 10C.

Results BEFORE thermal paste change:

and results after thermal paste change:

So MAXIMUM temperature dropped from 94C to 83C (that is below 85C safety limit).

Also multicore benchmark results improved in the Windows10 by few percent, which is probably due to reduced "throttling" of the CPU when its operating at lower temperature.

So it looks risks in changing in the CPU is either the work done (is screw tightened properly, etc) and

if there is used good thermal paste and if the thermal paste is spread properly.

I can't be sure if the installation work or the paste blew up the first results. But its more likely the

paste had something wrong in it, because also the CPU seller suspected the thermal paste performance of

the paste that came free with the CPU.

The benchmarking results show that CPU upgraded improved the results and upgrading 4Gb->8Gb memory seemed

to improve linux results and reduce the windows results significantly. Is the memory now "throttling" in windows10 mode also?

I hope I could understand why the 4Gb->8Gb memory upgrade is making Windows10 performance worse...
