HI. Ive just added 2x 1GB PC3200 DDR SDRAM to my Gigabyte GA81PE1000 motherboard (to add to my existing 512mb). I have 2 'orange' & 2 'purple' ram slots (128pin).
When my pc boots up, and checks the memory, it still shows only 512mb checked - and in Windows xp system in control panel, it shows as '512 mb' also.
I tried removing my old 512mb, just leaving it with the new 2 gb in, the led's flashed over &over & the bios screen didnt appear (ive tried combinations of different slots-but same problem, will only boot if it has the 512 in somewhere).
ive run everest- in the 'physical memory' section it says i have 512 mb. however in 'spd' it says in DIMM1&2 i have the 1gb's, & in slot 4 i have the 512 mb-wots 'spd'?
whats the reason for the new memory not being recognised as 'ram'? can anyone help? as far as i can tell its all the correct type - 3200,unbuffered,ddr sdram, 200 hz.
i ran crucials online check-which does show '2.5gb ram'.it also says im vista ready with 2.5g!

Your ram is not in the right slot or it could be your ram is not compatible with the new memory.or you didn't update your bios to support the new ram.or you have bad sticks of memory.

The only thing i noticed you didnt do is flash your bios with the newest version availble. Sometimes older bios dont support newer kinds of ram. Additionally some boards are very picky about what brands of ram they will decide to work for. Check with gigabytes website to see if they have a compatibilty list (many mobo manufacturers do). I would ditch the 512 as compatibility issues are massive when mixing different brands of ram. Best of luck.

try changing to different slots, make sure they are in right, i've run into this prob on other systems where the ram over rides the other, my IBM is funny I have 1.5 gig in 3 slots and for some reason if i switch them I run into the same prob. and don't know why! good luck!!
if crucial reads it @ 2.5 try putting in the 512 and running crucial and see what it recommeds as the max your motherboard will handle

Since the memory bays are color coded, that tells me that you must use your memory in pairs. If you use one 1GB stick you must use the other in the same colored bay. It is also possible that your motherboard doesn't support that much memory. Check your stats on your motherboard and see what the max RAM it can hold. If it can and will hold 2GB, ty using the other colored bays. but remember to put one stick in one purple bay and the other stick in the other purple bay.

Try putting 1Gb on DIMM1 (closest to processor) and 1Gb on DIMM3. Your computer should recognize 2Gb running on dual channel mode. If you want more, put the 512Mb on DIMM2 AND put another similar 512Mb on DIMM4. Your PC should recognize 3Gb on dual channel mode.
