1gb DDR2 667mhz not working

[hougtimo]

Hi,

I purchased 1gb of DDR2 667MHz ram for my new pc (am2, athlon64 x2 4200+), but when i put the new ram in the system didn't even post. put the old 512chip back in and it was fine again. Is this a faulty ram chip or is there something im missing here?

my dad has had similar problems somewhat like that, where one stick is DDR2, another is [whatever you call it] old RAM. your computer may not recognize DDR2, or its a faulty chip.

also, smaller RAM chips [in terms of MB] always go in slot 1. larger chips always go in slot 2. if they're equal it doesn't matter.

No, my pc can recognise ddr2 the 512mb chip im running right now is ddr2. Ive come to the conclusion its a faulty chip then

try resetting the cmos

Tried on another computer ?

Tried resetting the CMOS and we have no other DDR2 compliant computers to test it on

bonestonne is going in the right direction; it’s the chip size. The RAM is just incompatible with the motherboard .

WTF??? So I can't have a 1gb chip of ram in my mobo!? Thats just mental O_o

so you're saying a 1gig stick wont work? im finding this hard to be true b/c afaik all am2 boards can have a minimum of 1gig per slot.

Chip-size not module-size . AM2 boards are a bit more picky on RAM then S775, but I even found S775 motherboards that won’t accept 667MHz even when the specs say it will.
