Question about Lenovo 3000 J115 (7387-A11) Desktop Computer Bundle With AMD Athlon 64 X2 Processor 3800+ With Enhan... (W101787)

1 Answer

My Lenovo 3000 J115 type 7387-a11 runs on DDR-2 800 2x1GB. I install the same Kingston but in the 2x2GB size. It starts a little ways in and freezes. Reboots stop before the POST. Is there a BIOS update?

    Hi Joe, I did install my Kingston RAM DDR-2 2x2 and made sure it seated OK. I went straight into the BIOS setup and noticed it showed only 3008MB in stead of 4000MB. Since this is before the OS loads it has to show the actual amount.

    I saved it and exited and it would go a ways into the moving loading bar and freeze with a noticeable breakup in the video display.

    Even though it was a sealed Kingston package it is suspect. My sockets are good as soon as I put the identical but only 2x1GB Kingston back everything is OK. I BIOS flash wouldn't hurt if I could one.

    Also tomorrow I will try this RAM in another identical LENOVO. My old and new RAM are both 800MHz but on Lenove's site that you sent me it mentions 533 MHz. Now some better RAM auto toggles from 800 to 533 if there is a mix but in my case I don't know.

    As long as I use a single strip of the DDR-2 800 of 2GB it runs and shows 1.93GB and 800MHz in the BIOS.If I use 2 x 2GB the BIOS shows 3008GB and 800GHz but it will freeze during loading.
    Running Crucial software it recommends the following:

Your machine should support this memory configuration according to the specs found at the following link:

Just use your mouse to click on the link, which is the underlined and highlighted text just above. This will open a new web browser page automatically for you and allow you to view the information and items at the website indicated.

Kingston is one the better brand names for memory, so unless you just got unlucky and picked up a bad stick of RAM, I would think the problem is probably just that one of the RAM sticks is not seated properly. Try taking out one of the sticks and booting up your machine with just one of the new ones installed. Then try switching them out and boot up with just the other one installed.

Also try switching up the slot that you use for each one. Try each combination in turn and try to narrow down the problem to either a bad stick of RAM or a bad RAM slot on your motherboard. Hopefully just reseating them both firmly into place again will clear up the problem for you.

Always make sure you completely disconnect the power cord before opening up the case and working on the RAM. Keep yourself grounded to the case when you install or remove the sticks, and try not to touch the copper contacts on the RAM sticks to avoid any possible static damage.

I don't believe you would need a complete bios update to install and operate that memory. But if you are familiar with the BIOS settings on your computer, you may wish to take a look at the current RAM voltage settings there and make sure they are in line with the requirements of that new RAM.

Please comment back here to this page if you have any details to add, have any questions, have difficulty accessing the links, or just require further general assistance and I will respond as soon as I see it.

Thank you very much and good luck.

    Did your computer do the same thing when you tried booting it up with just one of the new sticks of RAM installed?

    I assume the motherboard on that has not been swapped out for something other than stock.

    One other thing you can try is to put the old RAM back into it so it will run and then goto WWW.CRUCIAL.COM and run their SCAN MY COMPUTER utility.

    This will scan your machine and tell you exactly what type of RAM your machine can run and the maximum capacity of each of the slots on your motherboard. It will tell you exactly what you have currently installed and what you should add in order to maximize the machine's performance.

    The 800 MHz should be no problem as you said.

    Good luck.

    I wouldn't worry too much about it not showing your every last bit of memory in the BIOS, I don't think it will affect the performance much anyway. A 32 Bit system won't use a full 4 Gigs of RAM anyway, since you have to subtract from that the amount of memory your video card has.

    The fact that your machine hangs during the start up with both 2 Gig sticks installed is a bit curious. You could try putting in both the RAM sticks, then take out the CMOS battery for an hour or so, then replace it. Then try booting it up again. See if that makes a difference after a few start ups.

    Good luck.

What Type and Make of RAM can system use?

Hi - It takes PC2-4200 240 pin ddr2 ram up to four gigabytes (it has two ram slots total - so it can use a 2 Gb stick per slot.)

Brand - I personally would buy any brand that was cheapest (make sure the seller has a return policy just in case).

Enjoy your upgrade!

Start with the power supply. Have it tested. Possibly burned out leads. Try swapping it with a good supply thats more powerful than the one youre replacing.
