Hi, I got a free D875PBZ based PC from my friend. It has only 512MB RAM though. I plan to upgrade it to 2GB (2X1GB DIMMs).

Does this mobo accept high density RAM (128Mx4 chips)(16 chips per module)
OR
Does this mobo MUST have low density RAM (64Mx8 chips)(16 chips per module)?

The corsair compatibility tool gave some products, but I couldn't find info if those modules were high density or low density ones.

Thanks
