Manual Density Bath Memory Copmpatibility Will My Mobo Accept High Density?

Memory copmpatibility will my mobo accept High density? - manual density bath

I have said an Intel motherboard 4gvm9i EP and specification of memory in the manual:
Two DIMM sockets DDR SDRAM 184pin
to support single-or double-sided 2.5v DDR 266/333 in technology 64/128/256/512mb dimmd. Supports up to 2 GB of RAM.
Memory of the machine, and agrees with the Program Memory Kingston
PC2700 (166MHz) - (DDR-333) unbuffered
Module registers: No
Module EPP: No
Width of 64 bits
errror: No

I have a little store on Ebay that seems perfect, but says that it is very dense and I do not know whether my motherboard supports high density. Is it possible all these outrageous to be? Thank you and yes, I've tried turning it off and on again.
