Emachines E732ZG Keeps Dying And Restarting After Ram Upgrade

Hi everyone,

Just new here. This seemed like the place that had the best Q&A in Google, so I hope that someone can help me.

I have an Emachines E732ZG. It's default ram is 2GB and it's really struggling with Win 10, so I bought some new 4GB ram to bring it up to 6GB. I can't figure out if the ram is faulty, it doesn't play nice with the original ram, or it's some other reason.

Original Ram: Hynix 2GB 1333MHz DDR3 CL9 SODIMM Non-ECC 1.5V

New Ram: Kingston 4GB 1333MHz DDR3 CL9 SODIMM Non-ECC 1.5V

When I put the new ram into the second slot (There are only two), it comes up with the usual load screen with the options to select F2 for BIOS or F12 for Boot Options, then goes to the Win 10 screen for about 5-10 seconds. The laptop dies and reboots. After three reboots it begins to get errors on the blue screen, which are all different:



I've reseated the ram multiple times, have swapped the 2GB and 4GB in the slots, have unclipped the CMOS battery multiple times (And waited 10-15 minutes between). It keeps cycling and going to a detect and repair screen, which only lasts a few seconds before the power dies and it boots again. I checked the BIOS for some way to adjust the ram speed, as per instructions on another thread on this site for same issue, but no go. I have not long upgraded from Win 7 to Win 10 on this laptop.

When I take out the new ram and put the original into the first slot, the laptop boots up fine and loads the desktop.

Could anyone please help me? Thanks!

  1. Two issues here.

    The 4 GB module uses 4 Gb memory chips which is not compatible with the memory controller (within the CPU).

    Another likely issue is that the two modules may not be compatible with each other anyway due to variances in memory characteristics (apart from voltage, timings, frequency, and memory chip density).

    Ideally, when wanting two memory modules, it is usually advisable to get a dual channel kit where the two modules are guaranteed to be compatible with each other. Trying to match two individual memory modules can be a lottery, they might or might not be compatible with each other. So a 2 x 4 GB dual channel kit might be the best way to go.

    This system (memory controller) supports up to 2 Gb memory chip density.
  2. Thanks for replying,

    I'm sorry, are you saying that the 4GB Ram I bought isn't compatible? I was a bit confused by what you said. I'm not great with computers and had to research all of this.

    I checked into it before I bought the Ram and even the Kingston site said that it was the correct one. The Emachines should be able to take up to 8GB according to information I got about that brand of laptop from various sites, including this one.

    I did try the 4GB Ram on its own in the laptop, so it's not a matter of it being incompatible with the other brand of Ram. If I put in two 2 GB Ram the machine isn't going to be powerful enough to do what I need. That's why I tried to bump it up to 6GB. If the new Ram worked well, I was going to replace the old 2GB Ram with another 4GB.
  3. Trying just the 4 GB memory module alone, does the laptop work properly or not? This is not entirely clear from your posts.

    Two individual (not from a dual channel memory kit) memory modules with the exactly same PRINCIPAL specs (capacity, voltage, frequency, and main timings) and part number may not necessarily work together (ie, they may be incompatible with each other).

    There are variation in electrical characteristics of every memory module, no two modules are EXACTLY 100% alike. In order for two (or memory modules) to work together (be compatible with each other), the memory modules respective characteristics have to be nearly the same.

    When buying individual memory modules, there is some risk that the modules may not be compatible with other modules. So in order to eliminate the risk of incompatibility, modules should be used from the same (dual channel) kit where the modules have been tested for and are guaranteed for compatibility with each other.

    Ultimately, it seems that a total of 8 GB is wanted for the laptop. So it is strongly recommended that a 2 x 4 GB dual channel kit be bought to replace the existing 2 GB and the existing 4 GB memory modules. Plus the memory bandwidth will be at maximum when using the same modules from the same kit.

    Even if the single 4 GB memory module works, and you buy another "same" 4 GB module, there is no guarantee these two separate 4 GB modules will be compatible with each other within the laptop. You might have to try several 4 GB individual modules to find a compatible combination.
  4. Oh, I see what you mean. Thanks for clarifying.

    No, the 4GB did not work on its own. The laptop went immediately into the continuous rebooting with the error screens. The only Ram that worked was the original 2GB and I have to keep removing the CMOS battery clip and run a detect and repair each time I remove it from the slot.

    So, I'll just have to keep buying dual channel memory to see which is the right one? That sounds awfully expensive. The 4GB cost me $55 and I can't return it since I got it from Ebay. Dual channel is going to be upwards of $90. I can't buy this type of Ram in a store, because it's an older type. It'll have to come from online. I just lost my job too, so I'll have to wait a few months to afford that, and the laptop won't even load the browser for several minutes in Win 10, because it's struggling so much. :(

    Well, thank you for taking the time to help me out. I really appreciate it.

    Does this one here look like the sort of ram you were thinking of?

    Thanks for the response.

    I suspected that the 4 GB memory module wouldn't be compatible with your laptop owing to the use of high density memory chips on the module. The high density memory chips are not compatible with your laptop.

    This 4 GB memory module could be on-sold to help recover costs in purchasing it, and the money from this sale could go towards purchasing a 2 x 4 GB dual channel memory kit instead.

    The Corsair memory you linked is standard DDR3 desktop memory, it is not compatible with your laptop. Your laptop uses SODIMM style memory modules only.

    I will try to find suitable and compatible 2 x 4 GB dual channel kit for your laptop and post the results in a while.
  6. Here are some compatible 2 x 4 GB dual channel kits -

    Mushkin - part number 997077 DDR3L-1333

    G.Skill - part number F3-10666CL9D-8GBSQ DDR3-1333

    Avexir - part number AVD3516001104G-2SW DDR3-1600

    Crucial - part number CT2KIT51264BF160B DDR3-1600

    There will be other compatible dual channel memory kits, but finding these others will take more time.

    Note that memory rated at 1600 MHz will automatically be run, or down clocked, by the laptop to suit the system compatible 1333 MHz memory frequency.
  7. Thank you very much for looking up the correct Ram type for me! I really do appreciate the help. My laptop is all I have and I need it to do practically everything.

    I did have a question though? The original Ram is 1.5 volts and the ones that you have listed as replacement appear to be 1.35 volts. That isn't too high for my laptop? This other thread on this forum, for someone with the same type and model laptop, tried to use the 1.35 v Ram and it didn't work. He was told that Ram was for newer model laptops and wouldn't work:
  8. The answer in the linked thread is incorrect.

    1.35 V DDR3 memory is basically 1.5 V DDR3 memory that uses selected memory chips that can work down to 1.35 V instead of the normal working voltage of 1.5 V.

    The actual reason the Crucial memory part number CT51264BF160BJ was/is incompatible with the E732ZG laptop is because this memory module uses higher density memory chips (4 Gb) which is not recognized by the laptop.

    Crucial part number CT51264BF160B IS compatible with the laptop because it uses lower density memory chips (2 Gb).

    So, 1.35 V SODIMM's should work fine, provided their memory chip density is no greater than 2 Gb.
  9. That thread was wrong? Ah, okay. It's really confusing when people sound like they know what they're talking about and give less experienced people the wrong information. I hope that other guy got some working Ram then on that other thread!

    Thanks, I'll try and get some new Ram using your suggestions. I'm having no luck getting the Ram I bought back to who I bought it from, so I'll have to sell it myself I guess.
  10. The "Best Solution" is not necessarily the correct one. It is usually up to the original poster to choose what they think is the best solution.

    That's unfortunate that the 4 GB memory purchased from a seller on eBay does not accept returns (because of incompatibility). The "returns policy" seem to vary according to the seller.

    Good luck with selling the 4 GB memory and in finding suitable/compatible memory for your laptop!
