Mine has double the amount of chips = low density?
It is also listed for use in an iMac 2008 which also means low density to me -
https://www.datamemorysystems.com/parts/apple/MB413G/B/ for example.
Look for Samsung M470T5663EH3-CF7 when searching for one for yourself.
By the way, some PC2-5300 that I ordered last week has turned up (2 x 1GB - totally not needed now), and being high density (only 4 chips per side) it gives beeps when put in the DLSD.
I reckon I've just been lucky in that I had that stick available and gave it a try, but we may be onto something here that can help others.
I wonder what would happen if I tried a 4GB module or someone with two good slots tried 2 x 2GB of this RAM?
Nothing good I reckon, but I might buy one if it's cheap enough.
Cheers

PS looks like you can't get these in 4GB modules
🙁
