I installed 2 Kingston ddr2 1 Gb 667/533 Mhz each memory chips but a system check shows that only 960 Mb of usable memory is installed. The bios DRAM chipset clock is set at auto. How can I get the system to use the full 2 Gb of memory? SS.

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.

Hi this model sopport 2Gig Memory Ram.

Please check in to your Bios system maybe share memory Video or capacity is setting

no need to update.. check the bus speed should be the same..

No you don't have to install a 64 bit OS. Only if you install over 3 gigs you MUST install a 64 bit operating system. 800MHZ is fine it will just back down to 667MHZ. your 32bit windows OS will see up to 3 gigs (minus graphics card memory). SO 2 gigs will work fine. Install one stick at a time and check in the OS and bios to make sure each stick works. I would say you possibly have a dead ram stick.

hi Dear,

You have to update your BIOS. If you have intel mother board just go thought their website and download BIOS Flash utility of your particular Board and Update BIOS.

The above fix will surely solved your problem.I had same problem as you and it's now fixed.

Sometimes, if the memory is a newer type, even though it matches the specifications laid out by the motherboard, there may be other factors like timing and voltage which cause a motherboard to not function with that memory. A lot of the time a motherboard manufacturer will be made aware of this problem and release a BIOS update to resolve it. Have you checked the motherboard manufacturer's website, ESC, to see if your particular motherboard is up-to-date with the most currently released BIOS version?

You can figure out what version of BIOS you're running if you go to Start -> All Programs -> Accessories -> System Tools -> System Information. On that first page it will list the BIOS version information and the date of that BIOS. If ESC has a newer BIOS available, you might try updating the BIOS to see if that resolves the issue.

Gateway's website says this motherboard will support 4GB of DDR333 or DDR400 memory. I would suggest testing each memory modules by plugging it into the board by itself, then rebooting. This way you can catch a bad DIMM that might be causing problems. If each one checks out then start adding one module at a time, rebooting after each one. If it still stops booting after you add a module, you probably have a bad system board, and only now that you are adding the extra memory are you finding that out. If that is the case, try contacting Gateway support. Maybe they would be kind enough to cover repair under warranty.

I had the same issue on this board where it came with a Samsung 512 MB 533 MHz PC2-4200 DDR2 DIMM. I put in a 1 GB Kingston with the same specs (533 MHz PC2-4200 DDR2) and it would not recongize the Samsung anymore with the system reading as 1 GB of RAM instead of 1.5 GB. Tried every configuration and would only see the Kingston. It would only see the Samsung if I pulled out the Kingston regarless of the slots I use. So, I just bought the exact same make/model of Kingston and it recognized that fine and the system now has 2 GB of memory (max this board allows). And, I had already installed the latest BIOS for this board from Intel before doing all this so wasn't an old BIOS. I'm figuring the board didn't like something about the Samsung memory (speed, module configuration, etc.) that made it not play nice with the Kingston. If interested I bought the DM8400A/1G Kingston modules. And, this board appears not to support dual channel memory. Only has channel A, slots 0 and 1, and I read need two channels to support dual channel (seems obvious). Boards that supports dual channel memory normally have 4 memory slots, two for channel A and two for channel B, then put in matching modules in slot 0 for channel A and B and have dual channel memory access. And if want more ram, then matching modules in slot 1 for channel A and B.

you can add up to 2 gb RAM using either 2 x 184 Pin DIMMs or 2 x 168 Pin SDRAM DIMMs. However that MB does support pc400. The supported RAM speeds are 100, 133, 200, and 266 MHz

You can buy a pair of Kingston 256 MB DDR SDRAM PC2100 (266 MHz) from the kingston website for under $50

Kingston is a well known and respected manufacturer of memory.
