i am running an amd on a system of pc100 .. i purchased 512sdram/pc133 i put it in and suprisingly .. it is not recognised.. i also tried putting it on its own .. and i get the same problem .. can u please tell me wat i can do to make it work thanks.

go here and look at post 1 and 6. http://computing.net/windowsme/wwwboard/forum/33118.html Did you check to make sure your Motherboard can handle 512MB RAM in 1 chip? A lot of the older MoBO's could only take up to a 256MB chip. Check the specs on your MoBO.

post your Mobo make and manufacturer. mostly likely 512mb can't be installed in yours.

well Legolas i checked my mobo specs and here it is . "Iwill KD266/KD266Plus Motherboard Maximum Memory: 3GB Expansion: 3 Sockets Virtually any configuration up to 3GB can be reached using any combination of Kingston's 64, 128, 256, 512MB, and 1GB modules." well here are the specs off my motherboard. it handles 512ram on 1 slot .. but for some reason it is still not working.. can i be because my motherboard is runin of pc100 ? can anyone please help me...

Try moving the 512 MB DIMM to another slot. Also, check the manual to see what DIMM slot should be used first.

High density chips! The latest memory bieng manufactured by most of the vendors uses high density chips (less chips to do the same job that older ones did). Many motherboards that are 3 yrs or older will not handle these chips. Check the manufacturer's web page, and I bet that is what you will find. If you contact the manufacturer, they will probably work out a trade for you. I just went through the exact same thing, and Kingston was very helpful. jim f

oh ok fletch. so wat did u end up trading it for and what was the memory capacity of your memory?
