High Density vs Low Density ...?

This is from the bay seller post :

Customer service is our top priority. To this end we want to provide you with as much information as possible so that you can make an informed purchase.
This listing is for high density memory. High density memory is a good low-cost computer upgrade solution and works well if it is compatible with your system. However, typically it is far less compatible than low density and will only work in certain motherboards.
Low density memory is compatible with 100% of the motherboards in the market and is typically of better quality. But this means it is more expensive than high density. For your reference, all branded memory you purchase from big box retailers is low density.
Please check to see if your chipset is listed below and contact your motherboard manufacturer to be sure it is compatible with high density memory. If you are unsure, we highly recommend that you purchase low density memory.
When comparing computer memory on Ebay please look for the words “high density” or “low density”. Some unscrupulous Ebay sellers do not mention whether their item is high density or not so you should also look at the chip configuration. For 1GB modules, high density is stated as “128x8” or “128x4”. Low density is “64x8”. Also, high density listings will typically have a list of compatible chipsets where as low density will not.

How safe is to actually get the high dens. memory (the price difference is 50% or more.!!).. any experience please...??

I don't think that's quite entirely right...

High density doesn't run 'slow' - it's the same speed rating.

Basically, advances in manufacturing lead to the ability to package more ram with less chips more efficiently, i.e. High Density. Some motherboards can't handle this. The end - I don't think there's more to it than that. I remember this being an issue with PC133 - after a time the only kind being made was high density, and some OEM motherboards like from HP couldn't handle it.

Yeah, compatibility is the single thing one really needs to care about. I mean, so what if some arbitrary parameter makes benchmark scores 1.5% higher when it's cloudy and you woke up on your left side.

There are three types of lies: lies, damned lies and benchmarks.
