[B]SOLVED[/B] HM70 chipsets compatibility with Intel Celeron, Pentium and Core processors

Hello everybody,

Thanks for reading.

I have a Acer Aspire E1-531 (Aspire E1-531-B9604G50Mnks).
I was looking for a new CPU to build into this laptop since it has a Intel B960 processor. I have looked up and found that this CPU has a socket G2, like the Intel Core i5 2520M. But when I looked for more information I found that only the socket isn't sufficient and I have to look for the chipset or something. This resulted in me getting CPU-Z and found the following parameters:



Well, here comes the problem. As suggested by CPU-world.com (http://www.cpu-world.com/Sockets/Socket%20G2%20%28rPGA988B%29.html) I checked the CPU-Upgrade (http://www.cpu-upgrade.com/mb-Intel_%28chipsets%29/index.html) and found out that HM70 supports Intel Mobile Celeron Dual-Core and Pentium Dual-Core Mobile.

The fun part is that Intel Pentium B960 isn't even listed when I click on HM70 express on CPU-upgrade. So I got the following questions:

Will I be able to upgrade my Aspire E1-531-B9604G50Mnks from an Intel Pentium B960 processor to a Intel Core i5-2520m processor AND will this work (haha)?
If not: What worthy processory upgrades are possible for me?

I'm sorry for any mistakes in this text as my native language is not English (Dutch). I'm looking forward for a respons.

Thanks in advance!

Peter

  1. Laptop CPU's are usually soldered in place, meaning removing it is impossible - without breaking it.

    Thank you for your reply Suzuki. But I want to know about the compatabilities of the named CPU's on this specific laptop/motherboard. I appreciate your information but I've seen people with the same laptop to be able to pick the CPU out of the motherboard without breaking anything. So I would like to know the answers to my questions first before I go through the hassle to figure out myself if that is the case in my laptopt too or not. For now I assume it is possible to take out.


    Quick google and I found the following video where someone picks out the CPU at 7:20.
  3. I was in the same position as you are in the past. For ~2 months i searched and investigated on a way to upgrade the CPU of my laptop (it was not soldered. was an i5-3230M and i was thinking of upgrading to an i7).

    My advice is: DON'T GO WITH IT. simply not worth it. you will have all sort of problems in the future if you do it, even if you do it 100% correct.
    Compatibility issues, thermal issues, trouble in finding a reliable seller that has the CPU you want without being used/damaged, etc etc. AND even if there is no problems, the improvement of the system simply will not be that much of a difference for what you have right now (i'm assuming you want a system upgrade for gaming and that sort of usage)

    My advice is that you:
    1- get a new laptop altogether
    2- build a custom build (desktop)

    IF YOU DECIDE TO GO THROUGH WITH IT:
    - try to first see if your CPU is soldered (search for that socket in google)
    - check a list of CPUs compatible with the socket
    - (try, but you will have to try hard) to find a seller of those CPUs
    - lastly, search for benchmarks on the web, and then decide on what you want.

    but again, i did what you are doing now, and i tell you, it's not worth it.

    good luck
  4. I have not used or have any experience with most laptop brands. That's all I know, bud. You're going to have to rely on someone else here. Expect a post soon, from someone that have more information.
  5. Suzuki:

    Thanks for your reply, I appreciate your effort! :)

    I see that I failed to post a youtube link concerning the replacability of the CPU.
    (https://www.youtube.com/watch?v=7jEZ_mljDeg).

    Blasc:

    Thank for the reply and your advice. Although it might not be worth it because of the possible following problems I still want to get atleast the information :) I have already found a CPU at an ICT company (with 3 months warranty) for 25 euros, that doesnt even nearly cover the money to get a new laptop. I already have a decent homemade desktop, not a pro build but OK. (AMD A8-6600K, 8gb ram, SSD etc). Since I dont really want to upgrade it to get a big difference I just want to upgrade it for a little difference. For example, this laptop isn't able to play League of Legends without being extremely annoying laggy. I suspect to get around that with an i5 2520M, but I want to make sure that I can use it before I buy it.

    So: The youtube video gives me the suspection that the CPU is not soldered
    The CPU socket is G2, (b960 and i5 2520m both are G2 too).
    I've found multiple sellers already
    I've already decided on the i5 2520. If this is not possible I would like to know why so I can search for mroe benchmarks in the future and decide myself if another is compatible or not.

    It all comes down to that I've read that it's not only the socket that makes it compatible or not (I've always thought that when i build a desktop PC). But now it seems that the chipset (or whatever it

    is) can make a difference too. So I would like to know if the i5 2520M will be swappable with my B960 and if this is not possible I would like to know why. So that when I find another CPU I can decide if that one will be swappable or not.

    Thanks for your replies and the effort!

    EDIT: I'm going to use the laptop while I'm doing my internship in Portugal ( I live in the Netherlands) and I want at least a low level of possibilities concerning gaming when I would like to (for example League of Legends).
  6. lol i was just searching, and the socket you have is the same as the laptop i had. So in short, yes, you can replace your CPU for a better one. but like i said before, you most likely have all sort of problems.

    basically, you are doing the same research and thinking of doing the EXACT same thing as me 1 year ago ^^

    so yes, any of the CPUs listed in the link you posted there (cpu-world link) can fit and replace your current one. But the hard part is going to find someone who sells it (and in good shape).

    like i said before mate, i advise you to go for a new laptop, or better yet, build a new desktop. much more fun i tell you :)
  7. Thank you for your second reply blasc. I would like to know why exactly you stopped doing research. I don't want a new laptop and my desktop gives me enough fun. It's just that I will be away from my desktop for a few months and in that time I want to give my laptop a little upgrade. Since I've already found an trustworthy seller. The only problem is that CPU-world says the following:

    To determine which processors are supported by your laptop or computer you will need to find out make and model of your system, and then search on manufacturer's website for upgrade recommendations for that make and model. Most manufacturers don't publish CPU support information for notebooks and OEM systems, but you may be able to find upgrade recommendations in product support forums on manufacturer website, or in forums on dedicated computer hardware sites. In addition to that, try to send an e-mail to manufacturer's customer support, or post in computer-related forums, although don't expect that you will get many responses. If this doesn't work then use CPU-Z or similar program to determine chipset type in your notebook, and look for CPU upgrade information for the chipset. CPU support data for Intel chipsets can be found on CPU-Upgrade.com in Intel chipsets section, or on Intel website. Be careful with this method as it's is less reliable.

    And so I did the last suggested thing since I couldnt find my manufacturer information regardign this. And that is where I found the problem I described above and want to get a solution for.

    I appreciate all your replies!

    I was just searching, and im sorry to tell you that the highest CPU u can go on that laptop, because it has chipset HM70, is this one:

    http://www.cpu-upgrade.com/CPUs/Intel/Pentium_Dual-Core_Mobile/2030M.html

    that chipset is apparently locked to Celerons and Pentiums. Some guys report that the computer just shut down after 30 min, when using an i5 with that chipset (apparently, Intel locked it out).

    So guess you will have to search and buy the CPU in that link.


    btw (i was gona post this before doing more research):
    my previous post was written before reading your last post sory.

    wow 25€ for a good upgrade and with warranty! nice :)

    yes it is possible to remove and change that CPU. i have once taken my laptop's CPU out of the socket when i wanted to change the thermal paste of it. for an easy clean i took it out. the hardest part is only the copper heatsink, which also passes through the GPU and is also attached to it, so carefull on that.

    if you are that decided, then i tell you to go for it. remember that the CPU will fit nicely into the socket, no need for big pressure ^^
    also check some tutorials on best way to apply thermal paste (in case you never done that)

    post some pics or at least tell us how it went! \o/
    (i'm happy for you, since you are going for what i once wanted to do, but for me, the upgrade simply wasn't worth it)

    EDIT: one of the threads talking about the lock down after replacement of the CPU -> https://forums.lenovo.com/t5/Lenovo-B-and-G-Series-Notebooks/Shut-Down-after-CPU-replacing/m-p/1234401#M37542
  9. here is a link to compare the CPU you have now, and the best you can get:

    (copy full link and paste it on browser ^^)

    Haha, thank you for your ethusiastic respons!

    That's exactly what my problem is. That HM70 thingy, whatever it is. But the problem is that that list doesn't seem to be complet since my current processor (B960) isn't listed there either.

    Can you explain what this means? Since I dont know that much about computers hehe. The heatpaste will be no problem. Build my current PC myself and replaced it on many PCs!

    I'm not sure if I'm still going through with this if the 2030M is the highest I can go. I secretly really hope I can still put the 2520M in it since that would solve a lot! But if you are a 100% sure that I can't go higher than the highest that is provided in that list I will think about it and consider it solved for now, only if you are 100% sure that only the listed ones are compatible ;)

    Thanks!
  11. Since the Pentium B960 uses a PGA socket that means it can be replaced. If it were a BGA socket, then that would mean the CPU is soldered into the motherboard and cannot be replaced.

    The problem is there are no Acer Aspire E1-531 with a CPU that is better than the Pentium B960. While a Core i5-2520m (the PGA version) may fit into the socket, the BIOS may not be able to recognize it and therefore the laptop may not even boot up. The BIOS more or less contains a list of compatible CPUs for the laptop. If the CPU is not on the list, then....
  12. Well everybody.

    I'm afraid blasc and jaguarskx gave me the answer.
    Eventhough it wil physically fit it won't be able to run because of the chipset (grr).
    Considering changing the motherboard is not an option it's either buying a worse processor than the 2520 or leave it at the B960.
    I will think about it and if I decide to swap it with a 2030M I will post it.

    Everybody thank you for your replies and really thanks I didnt buy the processor yet (I always thought that if the sockets would match it is no problem).

    Have a good day!

    are you nuts? what era do you live?
    now most CPUs are sitting in sockets, so can be easily swapped. all depends on chipset and availability of cpus.
