Hi, It depends on what version of windows you have. If you have a 32 bit OS, then it will only see 3Gb. IF you have a 64 bit version OS, then it will recognize greater than 3Gb.

Check the system manual for how many gb of ram your system supports, try installing each of the memory stick to make sure it is functional, this way you can make out the which one isnt working or incompatible if any.
The system cannot recognize if it does not support the one you are trying to install.

GA-EP43 -UD3L motherboard will not boot with 16 GB of memory


Time to RMA, sounds like you have a faulty memory channel on the MB. Possibility the slots are not getting enough power to handle all 4, you try to see if you can increase power in bios.

Issues with 2gb 32ddr dell memory compatible in dell gx280


Unfortunately, the CPU on these computers may be capable of handling the 2GB memory, the motherboard isn't on either system.

The specs for the Dell GX280 are available here: http://support.dell.com/support/edocs/systems/opgx280/en/ug/specs02.htm . This system takes 400 or 533 MHz DDR2 non-ECC memory and the form-factor determines the maximum memory. In the mini-tower format, you have 4 DIMM slots and can have 4 GB of memory. In the small form factor, it takes 2 GB max.

The Dell E310 specs are available here: http://support.dell.com/support/edocs/systems/dim3100/en/sm/specs0.htm . This system can only support 2 GB (2 x 1 GB) memory.

I wish that I had better news for you.

(who had a similar Pentium 4 computer with the 1 GB limit. Since that system was running a 32-bit system and only actively addressed 3 GB, I didn't try to put 2 GB sticks in any of the 4 memory slots.)

I bought a new 1GB ram(DD2) when i insert it it nt work bt whenever i insert it with old 512MB ram then its work bt in bios setting only show the 1GB ram


Maybe 1GB is the maximum amount of memory that your system will hold. And maybe your system likes memory to be in pairs, so when you put the 1GB in by itself it didn't work, but when you put it in with a 512MB it works.

From what I can tell the Dell Precision Workstation 670 does support over 4GB of RAM. However when you have over 4GB of RAM installed in the system you have to have the Memory Cooling Shroud connected to keep the memory cool. Also this is only shipped out when the system is ordered with over 4GB of RAM originally. If you do not have this part you can order it from Dell buy calling 877-671-3355.

Let me know if you have any more problems or questions

I upgraded the memory on my Thoshiba Satellite to its maximum 4Gbyte. I added two 2GByte memory module. But my memory test program and Windows operating system says that only 3Gbyte memory available. Does...


It means that your version of windows can only use 3 GB of your ram. This is a limitation of 32bit operating systems, due to the way the memory is addressed, which only allows upto 3GB. If you want to use 4 GB or more then you'll need a 64bit operating system. You do have a 64bit laptop so it's just a matter of installing a 64 bit version of windows. Or another operating system if you prefer, I can't stand windows personally.

If you've already got a 64bit operating system installed, then there may be something wrong with one of the modules, in which case you should be able to get a replacement.

Hope this helps.

This board has a dual channel memory. To function correctly both channels must be identical otherwise , as you can witness, it chokes. To put it simply you must put either 2 identical sticks of memory or 4 - it can't run on 3.

RAM Upgrade


How much memory your Windows OS will recognize depends on which version of Windows you are running. 32-bit versions of Windows will see (and utilize) only 3GB or 3.5GB. To utilize more memory, install a 64-bit version of your OS. More information about OS memory maximums can be found at http://www.crucial.com/kb/answer.aspx?qid=4251

Not only is there a maximum amount of memory that your computer motherboard can accept, there is also a maximum amount of memory that your operating system (OS) can accept. For instance, when you install 4GB of memory in a 32-bit Windows system (the most common version; 64-bit systems are typically used by high-end users), your system reports only 3GB or 3.5GB.
First , we can assure you, there isn't a problem with the memory. While Windows allows for 4GB of memory to be addressed, it does not equate to 4GB of physical memory. Some of the memory (regardless of how much you have installed) is reserved for use by the devices that you are using, such as a graphics card, PCI card, integrated network connections, etc, meaning it is unavailable for use as normal main memory. Upon startup, your system calculates the amount of memory needed for these devices; if you haven't maxxed out the memory in your system, it's invisible to you, and all your physical memory (the installed RAM) is available for use. However if you've maxxed out the DRAM in your system, this amount will be deducted from your physical memory, so you can't use 100% of your DRAM. The maximum memory limitation varies by operating system, For instance, the 4GB memory limitation doesn't exist in 64-bit versions of Windows.

nope, 1 slot can only accomodate 2gb of ram. and also take NOTE that 4gb can only be read if the windows is running 64bit ,now if the system is running 32bit and there are 4 gb of ram installed on the system . The system will only read 3 or 3.5 gb of ram.
