Hey, im just wondering what is the maximum an aspire 5739G can have? seem to find random answers everywhere, some say 4 some say 8 but it seems like its the same machine and name but there is alot of difference parts inside them.speccs.jpg

 

These are my speccs for it, reason for upgrade is i want to use the 64bit windows 10 on it.

    Hi,

    You have 32bit Operating system and it will utilise up to 4GB memory, that's the maximum you need.

    You should be able to run the 64-bit version on 4GB.  No guarantees but the BIOS will probably recognize 8GB replacing the two 2GB modules with two 4GB modules. Jack E/NJ

    Hello, one week ago I successfully finished an upgrade of my aspire 5739G (10 years old!).
    Replacing the original Intel Core2 Duo P7450 (2.13GHz, 3M L2-cache) by a P9700 (2.8GHz, 6M L2-cache) which is not in the official Acer list, and the RAM from 2 x 2GB to 2 x 4GB (Samsung). The BIOS is at V1.3311.
    Though the notebook was provided with Windows 7 (64bit) I'm running Windows 10 Pro (64bit) for years with the original configuration.
    The GPU is a GeForce GT 240M (driver version 341.1), 1GB and can't be upgraded, afaik.
    As Microsoft keeps from providing Windows 10 (2004) through Windows Update because of reported problems with legacy GeForce GPUs and driver versions below 385, I gave it a try and installed it via Media Creation Tool.
    No problems at all and my notebook is faster than ever.
    A big THANK YOU to Acer for such a valuable product.

    Would like to give a shout-out to Jazzero for his post. Upgraded my same age Acer 5739G to the above processor (acquired from ebay) and 8GB of RAM and a 512 Gb Samsung SSD. Found two videos on YouTube for disassembly and assembly of the Laptop which were so useful as i'd never taken a laptop apart before, and it is so layered, with so many ribbon cables to detach here and there. But apart from the white LED's on the media player touch buttons seemingly needing time to warm up now, and the fact the HD had to be initialized as MBR and not GPT (Acer BIOS wouldn't recognise it otherwise), it all went swimmingly!

    Hello. :-) And has anyone tried to put 2 x 8 GB of RAM (total 16 GM) into an Acer Aspire 5739G laptop and was it visible in the BIOS / UEFI or in some operating system (e.g. some version of Windows / Windows Server / Linux)?

    If you put two 8GB mo0dules in, it would either generate an error at the start of POST or just show the maximum of 8GB the chipset supports. The 5739G model line uses the Intel PM45/GM45 Express Chipset, which has a hard limit of 8GB total memory.

    Hmm, OK. My chipset information (from "RAMinator" application): northbridge - "Intel PM45 rev. 07", memory type - "DDR3" (1.5V), channels - "dual".

    1. But how do we know that there is a hard limit for this chipset?
    2. Has anyone tested it in practice on two twin modules ("Dual Channel"), whether more than 8 GB of memory will not be detected during the POST procedure (turning on the laptop) by the BIOS? (I would check it myself, but I only have one 8 GB module, now... The information provided in service manuals is often underestimated... - Here was the 4 GB only, but now we know it is at least 8 GB!)
    3. I have my BIOS flashed to the unofficial very carefully unlocked version of 1.3311. And is it possible to upgrade the firmware of this chipset or northbridge chip only?

    It's pretty easy to find the spec sheet on the PM45 chipset. The only difference between the PM and GM is whether there's a GPU embedded for onboard video. I doubt if anyone has tested trying to put more memory than what the chipset supports, but you are welcome to try if you have the memory hanging around. I don't think it will cause any damage... The SG is likely only going to show the tested configurations, hence the 4GB maximum they show in the specs. Possibly when they shipped they didn't yet have access to the larger memory sticks. I can't comment on modified BIOS versions…

    Thank you, very much! And how you think, is it possible to upgrade the firmware of this chipset or northbridge chip only - not upgrade the BIOS but upgrade the chipset working with RAM (with official, not modiffied version, of course - that's what I meant)? Maybe then we can unlock the hardware limitations of the northbridge itself (which then would really software limitations, in its firmware)? Is this theoretically possible?

    I don't think so. The memory size limitation is based on the number of address lines the chipset uses, and that's a hardware limit, not firmware.

    That's what I was afraid of. But I don't trust big corporations and I'd like to check it out practically. What do you think... 1) Does the northbridge have its own firmware? 2) And if so, can it be flashed at home?

    Simplest way is to download the Acer Aspire 5739 official service guide here as its available for download and you have all the specifications of this laptop there and all that you need to know about this laptop.
