Hi,

I am looking to find out the CPU upgrade options for a Hp Pavilion 15-e047sa laptop which is fitted with an Intel Core i5-3230M.

thanks,

Hi,

According to the service manual the compatible CPU you can upgrade to is the 

Intel Quad Core i7-3632QM 2.20-GHz processor (SC turbo up to 3.2-GHz; 1600-MHz FSB, 6.0- MB L3 cache, 35 W)

part number  701658-001

You can see the steps to upgrade the CPU on page 85 of service manual:

You can also look at the HP videos for that model which can help with any upgrade

Remember to replace any thermal paste and pads with quality material such as Arctic MX-4 or similar.

Let me know if you need any further help,

David

Hi iomare,

Thanks, yes I was just looking at the manual and had noted the i7-3632QM listed.

The laptop has an i5-3230M CPU and it would appear that both it and the i7-3632QM are G2 (rPGA988B) socket processors, as they are listed on the page below.

http://www.cpu-world.com/Sockets/Socket%20G2%20(rPGA988B).html

Also according to the manual the possible chipsets on the motherboard are Intel HM76 Express and Intel HM86 Express, so checking if the chipset will support the upgraded processor I found this.

Looking at cpu-upgrade pages below, as the processor is currently an i5-3230M it appears that the chipset will be Intel HM76 Express, as this processor is listed on it's page (although in the service manual while it lists both the HM76 and HM86, only the HM86 is ticked at Intel processors?).

http://www.cpu-upgrade.com/mb-Intel_(chipsets)/HM76_Express.html

http://www.cpu-upgrade.com/mb-Intel_(chipsets)/HM86.html

The cpu-upgrade page for the Intel HM76 Express also lists the i7-3632QM processor, so it looks like the chipset supports it ok.

From what I have now read the other thing that could affect whether the i7-3632M will work is whether the BIOS will support it. I have looked at the support page at

https://support.hp.com/us-en/drivers/selfservice/hp-pavilion-15-e000-notebook-pc-series/5355006/mode...

which doesn't give any details re processors, so I am assuming that the latest update (and previous) will support i7-3632QM

Thank you for your reply and the links that you included.

Hi,

Did you ever manage to do this? I have the same laptop & problem that needs solving. I don't want to buy a cpu if I'm going to waste my money.

Thanks

Hi Josh,

I didn't pursue it in the end and it is so long ago I cannot remember why in the end I didn't do so. So I am afraid unfortunately  I cannot give you any further information that would be of help.

One thing that does come to mind though and that came up with another HP model of laptop, I don't remember what the situation was with this HP 15-e047sa model.  Although everything might be saying a particular cpu upgrade will work, you need to actually check that the type of cpu fitted is not one that is soldered on to the motherboard, rather than a removable one in a socket.

best regards,

Ian

I see in the manual, you can replace with core i7-3632QM, but with core i7-4702QM: I think cannot, the socket incompatiple. I dont know why HP put it in the list.
