    mother board cannot recognise ram

  • malden86 Mar 09, 2008

    I have two 1 Gig sticks of RAM and the MB only recognizes one stick.

    Could I use 1 2 Gig stick instead? I'm also using Windoes XP.

  • greyrabbit Jan 19, 2009

    My K7S41GX MoBo will only recognise a single IGB RAM stick fitted in either DDR slot. When (1GB) sticks are fitted in both sockets only the RAM in slot two is found. I'm running Vista, but is it a Bios or Motherboard limitation/fauly.

Some old mother as that cannot recognize ram more thatn 1 gig. Try just using 1 ram of 1 gig or if you want to upgrade just upgrade it up to 1 gig.

I have a eMachines T3646 Motherboard MCP61SM2MA-RS2H and I wanted to upgrade the Ram on it. I was told that this type of ram was compatible ( Crucial 1GB 240-Pin 128x64 DDR2 PC2-6400 CL6 ) I stuck two of...


Not sure exactly as to why you can run the one, and not the other, but I am familiar with 'speed compatibility' issues, especially with Crucial RAM (which is still good memory, BTW)... I looked up your computer's memory specs on this site, and they're in the biz of selling, but pretty reliable as they are independent. Check out where it shows the speed at PC2-5300--any time you want to upgrade, you try and match the upper limits of that particular characteristic, so maybe it'll run one Crucial stick at '6400', but not two, since--even though most RAM packages 'say' they're 'backwardly compatible, speed-wise', many of the better brands sell RAM that, when installed in pairs, run at their upper speeds, or 'a certain speed', we'll say... So--again, this is easy--try a pair running at the slower speed. The best news is, if you bought the Crucial RAM new (as I suspect you did), most retailers will return your money on hardware purchases within 30 days afterward.

Acer aspire m5100, AMD Athlon 64bit x2 dual core processor 5000+ 2.60Ghz. Win Vista Business 64bit. When i upgrade and put more than 3GB of ram into the machine, it turns off the lan and my display driver...


Acer official site says:-
Up to 4 GB DDR2 533/667/800 MHz SDRAM
(dual-channel support on four DIMMs)

Try these bus speeds and for dual-channel support read this article :-

Dual-channel architecture requires a dual-channel-capable motherboard and two or more DDR, DDR2 SDRAM, or DDR3 SDRAM memory modules. The memory modules are installed into matching banks, which are usually color coded on the motherboard. These separate channels allow each memory module access to the memory controller, increasing throughput bandwidth. It is not required that identical modules be used, but this is often recommended for best dual-channel operation. It is possible to use a single-sided module of 512 MB and a double-sided module of 512 MB in dual-channel configuration, but how fast and stable it is depends on the memory controller.

If the motherboard has two pairs of differently colored DIMM sockets (the colors indicate which bank they belong to, bank 0 or bank 1), then one can place a matched pair of memory modules in bank 0, but a different-capacity pair of modules in bank 1, as long as they are of the same speed. Using this scheme, a pair of 1 GB memory modules in bank 0 and a pair of matched 512 MB modules in bank 1 would be acceptable for dual-channel operation.

Modules rated at different speeds can be run in dual-channel mode, although the motherboard will then run all memory modules at the speed of the slowest module. Some motherboards, however, have compatibility issues with certain brands or models of memory when attempting to use them in dual-channel mode. For this reason, it is generally advised to use identical pairs of memory modules, which is why most memory manufacturers now sell "kits" of matched-pair DIMMs. Several motherboard manufacturers only support configurations where a "matched pair" of modules are used. A matching pair needs to match in.

Good luck

I just need to upgrade the memory on a Dell Precision 530MT.. can't seem to find the exact type of memory it needs.. any ideas?


HELLO Paul

When installing memory modules in the system board sockets and not using the optional memory riser boards, observe the following guidelines:
  • Each memory socket on the system board must be occupied either by a RIMM or a CRIMM.

  • Memory sockets must be upgraded in matched pairs. In other words, two sockets in a pair must contain modules of identical capacity, number of components, and speed. See "System Board Memory Components" to identify pairs of sockets.

  • Mixed pairs of ECC and non-ECC modules all function as non-ECC.

  • Be sure to install a RIMM in socket 1 first (closest to the processor) before installing modules in the other sockets.

  • The system board supports PC600 and PC800 memory modules.

Need upgrade Memory for Intel D865GLC/D865PESO


If you goto www.crucial.com and use their memory checker tool you can find out which RAM you need as well as the maximum your motherboard can handle.
Next open your desktop or the section on the base of your laptop where the RAM resides to make sure you have a spare slot and how many slots you have.
It is recommended if installing more than one memory module that you used a matched pair. This is to ensure compatibility. A matched pair is when you buy two of the exact same modules (same spec and manufacturer, model etc.).
Hope this helps,

Graphic card for GA-8IPE1000 series


HI there.
There are loads of makers of memory and graphics cards out there to choose from.
For the ram i would recommend Corsair or Kingston, you can get this ram as a matching pair so the both run at the same speed, the best ram to get is DDR 400.
As for the graphics card, i recommend ATI radeon X1650 Pro 512MB graphics card.
These upgrades will make your machine purr like a kitten with an excellent gaming experience.

Good luck and thanks for choosing FixYa!!

RAM upgrading


You have 3 banks of 2..... Max is 6GB
you'll need PC 133 ECC SDRAM DIMMs

put them in using matched pairs is recommended
i also think i would not purchase the cheapest memory...middle to better memory so that it will work without hassles.

Added 2g to a dell dimension 3000, only 1g recognized


Dell has a really good support site. You log on, enter your service tag number (on the top of side of your PC) and they will tell you exactly how much ram you support, the type of ram needed and how many slots it has. If it was a matching pair then it should be working, unseat it and reseat it, it may not be in all the way. If still don't show then put it back in the old computer and see if it reads it. If not then the RAM stick got damaged during the move. But no doubt you should be able to handle more that 1GB of RAM. Good Luck, let me know if you have any questions.

Added memory but one memory card (Original) not recognised


OK, according to Crucial.com your RAM does need to be installed in matched pairs.

Here is a link for your computer information:

If you get another 512MB module and install both pair, it should work well.
