Don't worry about what Windows says...check your BIOS. Also the other stick must match in type ddr in speed exactly for it to work. Last choice take it out and reseat it. If it doesn't work or if the ram is damaged you will hear 4 very long beeps when you start up.

DDR2's only showing half installed RAM


IF THE SYSTEM SAYS YOU HAVE 1GB RAM THAN YOU HAVE 1 GIG OF RAM, EVEN THOU SOMEONE TOLD YOU YOU HAD 2-512MG=1GB.

HERE IS HOW I SEE WHAT YOU ARE SAYING YOU HAVE 2-DDR-2 1 GIG STICKS THAT MEAN IF 1 IS INSTALLED THAN YOU HAVE 1 GB AND IF YOU COULD GET 2 STICKS WORKING TOGETHER THAN YOU WOULD HAVE 2GB RAM.
1 CHIP SET = 1GB RAM
2 CHIP SET = 2GB RAM

YOU MOTHERBOARD MAY NOT ALLOW THAT MUCH RAM, OR WHAT I MEAN THE BIOS MAKE UP THE AMOUNT OF RAM.

TO RULE OUT ANY BAD CHIP SETS OR GOOD RAM OR BAD RAM.

TAKE THE PEACE OF RAM THAT IS WORKING OUT AND REPLACE IT WITH THE OTHER PEACE AND SEE IF IT WILL RUN.
IF IT WORKS THAN LEAVE THAT ONE IN PLACE AND INSTALL THE SECOND PEACE IN THE SECOND SLOT.
IF BOTH CHIP SET ARE GOOD THAN BOTH SHOULD WORK OKAY TOGETHER.
IF THERE IS A PROBLEM, IT MAYBE SOME DUST IN THE MEMORY LOTS
OR THE SLOT MAYBE DAMAGED.
OR
THE CHIP DESIGN LAYOUT MAYBE THE OPPOSITE SIDE, THIS MAY MEANS THE CHIPS MAY FACE EACH OTHER, OR FACE OUTWARD FROM EACH OTHER.

RAM DDR2 PC 1300


DDR 2 will _not_ work the way it's supposed to in a DDR slot, if at all. If you want to see what memory your computer can use, go to crucial.com or similar website for a free scan of your computer. From the spec. sheet it looks like your machine takes a maximum of 2 sticks of 1 gig each (for a total of 2 gigs) DDR SDRAM, either 333 or 400MHz of memory

Memory installation


Most likely, it is a limitation of your motherboard. Not all motherboards or computers can physically read all types of memory or they may have memory limitations. For instance, I was working on an older Gateway this week. It had 2 memory slots but the maximum amount of memory the computer would recognize is 512 MB. Therefore, if I had put to 1 GB sticks in, provided the computer could use it, the maximum the computer would be able to see or use is 512 MB. In this instance, that is most likely the scenario. The best thing to do is to go to www.crucial.com and run the system scanner. It will tell you how many slots you have, what the maximum per slot capacity and the total capacity of your computer is.

Thanks and please take a moment to rate as fixya.

RAM Recognition 835GM PC Desktop


the memory is dual channel, so you have to use matched memory for it to work 1gig in each slot if possible, check the 1 gigs and 512's to see if they run at the same bus speed, if they are not matched there is your problem try a gig and a 512 in slot 0 to see if it picks the memory up, also there is sometimes an option in the bios to dissable dual mode

Gateway sb-4100-b won't recognize new memory


Check the owners manual of your computer for the correct installation of 2 sticks of memory, this can be critical on computers with 2 banks of 2 slots, it will also tell you the maximum ram that will work. If you do not have the manual, go to the manufactures website and then go to the support link, and browse for memory installation. BPCS
