Serious RAM questions,, please

I posted some OK prices in Steals & Deals.
This techno quote has me wondering,
, how to tell the diff
and What do you Need for your board
and How do you tell what you need?

----there are a lot of the 256 and 512 megabyte DIMMS made with 32x4 high density chips that will not work properly (only register half the RAM) on Intel motherboards

Only recently did I hear about RAM density. A friend showed me his mobo's manual (not Intel) that mentioned this matter.

To date, several searches on the topic have not clarified the issue. I have seen sticks with fewer or greater numbers of individual chips that claim the same specs. Maybe it is related to the storage capacity of each chip. However, it does not make sense that a mobo should care about how a RAM module does the business of handling the data.

I look forward to the advanced answers to this question.

I have that same question That you do but I whant to know which is faster. I would assume that the fewer the chips the faster it runs. I do know that the the memory I was looking came in 8chips 8Mb (megabit per chip) x8 or 16chips 16MbX8 so there is more memory per chip but is that A good thing or not.My Abit board does not support X4 Chips.

***Important Information Regarding the High Density (32x4) 256MB PC100 Memory
This modules are made using a high-density 32Bit DRAM Chip. To use this module, your motherboard must be able to accept a 512 MB DIMM in each memory slot. If not, your system might only recognize the chip as 128MB. - Also note the "Basic / Market Grade - Generic Grade" modules are built using 4 layer module boards and are may not match CPU manufacturer recommendations for higher speed PIII Coppermine / Athlon Thunderbird systems.
From First Choice Memory (http://www.icentral.com/html/1stchoicememory/page493.html)

As near as I can tell from researching a few different sites, "low density" SDRAM uses 64megabit chips, and "high density" SDRAM uses 128megabit chips. Some motherboard chipsets have great difficulty recognizing the 128megabit chips for what they are, and revert to thinking that they are 64megabit chips, hence, they only recognize half of the actual capacity.

Am I right? wrong? close?

(I like this type of post, it makes me think and I learn something by doing a little research. Thank You for challenging us. http://www.sysopt.com/forum/smile.gif)
