Upgrade Processor Part 2 (i5-450M chipset HM55)

Hi all,

I posted a similar question previously about upgrading my cpu, however, I have done futher research and wanted to start clean again. The question is still what is the highest processor I can possibly upgrade to.

 

System Specs:

 

Model: HP DV7-4070us

Processor: i5-450M (2.40GHz, socket 989 rPGA)

Chipset: Intel HM55 (or the Intel 5 series) 

RAM: 8 GB

Storage: SSD + Secondary HD

 

After research more deeply, I have found this link: http://www.cpu-world.com/forum/viewtopic.php?t=18837

Similar situation: "If it's not a BGA chip, you should be able to replace with Core i5-560M, i5-580M, or i7-640M CPUs. If you have Intel HM55, HM57, PM55 or QM57 chipset then quad-core i7-740QM / i7-840QM CPUs may also work. "

 

So does that mean I can get the i7 quad-core CPU then? I understand that quad core CPU requires a different mobo, but it seems to me, from that forum link and also from Intel's site that with my current setup, I can potentially upgrade to:

i7-740QM (? kinda iffy about this one)
i7-840QM (? kinda iffy about this one)
i7-640M
i5-580M (Almost 100 % sure)

 

I greatly appreciate ANY response that would help me. I apologize again if anything I have done/said sounded noobish, I can only try at something I have no experience in :smileyvery-happy:



P.S. Another list I found pertaining to my chipset, however there is a disclaimer stating that using the list method may not be as accurate.

 

P.P.S Further investigation, I have found that the only processors that use the socket g1 or 989 rPGA are: "The current CPUs to use this package are the Core i7-6x0M series, the Core i5-4x0M series, the Core i5-5x0M series, the Core i3-3x0M series, and finally the Pentium P6x00 series and Celeron P4x00 series which were released on March 28, 2010. However, not all of these are available for Socket G1, as some of them are only available in a BGA package." (http://en.wikipedia.org/wiki/Socket_G1)

Re: Upgrade Processor Part 2 (i5-450M chipset HM55)

Hi:

 

When you look at the service manual for your notebook, in chapter 3, you will see that there are different motherboards for dual and quad core processors, so installing a quad core processor where you had a dual core processor, is definitely out of the question.

 

The motherboard must be replaced.

 

http://h10032.www1.hp.com/ctg/Manual/c02666747.pdf

 

IMO, you can go to the i7-620M, as that is what is listed in the BIOS release notes for F.08A -- Presuming of course, that you have BIOS vF.08A or newer installed in your notebook.

Fix/Enhancement:
  • Adds BIOS support for the Intel Core i5-520M, Core i5-540M, and Core i7-620M K-0 Stepping Processors.

 

You are to be commended for your extensive research, indicating you are by no means a noob.

Re: CPU upgrade

Hi:

 

Below is the link to the service manual for the G62 notebook series.

 

http://h10032.www1.hp.com/ctg/Manual/c02542102.pdf

 

Supported processors can be found in Chapter 1 on page 1.

Re: CPU upgrade

I have HP Envy-17 1080eo with i5-450M -processor. According to user manual it seems that Envy uses same system board for all processor variants, even for Q-core 45W versions. Is that reallý the case and into what versions I can upgrade my CPU?

Re: CPU upgrade

Hi:

 

I do not feel comfortable answering your question regarding what processor you can upgrade to in the  Envy-17 1080eo.

 

Most of the notebooks I am familiar with use different motherboards for the dual and quad core processors.

 

Looking at the manual for yours it would appear the same motherboard works on all processors and only the fan/heatsink is different for the dual and quad core processors.

 

So, on paper it would appear you can upgrade to the Intel Core i7-820QM 1.73-GHz (SC turbo up to 3.06-GHz), 45W processor if you also change the applicable heat sink to part # 608650-001.

 

But again, this is only what I can determine from reading the manual, and in no way will I go out on a limb and tell you that upgrading to the  i7-820QM will definitely work.

Re: CPU upgrade

Thank you Paul for your answer, got your point...

 

I assume that BIOS support all these processors as such?

I was at the begenning thinking that I could upgrade to i7-640M as it is more close to current MCU but a bit more powerful. But I assume that BIOS is not supporting that one.

Re: CPU upgrade

You're very welcome.

 

Reading the BIOS release notes show that for BIOS version F.07A, support was added for the following processors:  i5-520M, Core i5-540M, and Core i7-620M K-0 Stepping Processors.

 

BIOS version F.1B adds support for the i5-480M K0 Stepping Processor.

 

So, if your notebook has BIOS version F.07A or newer installed, you can surely upgrade to the i7-620M processor.

 

Yes, I have Finnish roots.  My father's parents emigrated from Finland to Massachusetts, USA in the 1920's.

 

My grandfather came from Kälviä (now part of Kokkola), and my grandmother came from Kauhava.

 

I keep in touch with my many cousins in Finland via the internet.

 

Best Regards,

 

Paul
