Can a computer with only DDR-SDRAM capability(Not necessary DDR2) use DDR2 RAM?

How come DDR2 RAM are cheaper than DDR RAM?

No.

DDR2 is not backwards compatible with DDR SDRAM.

DDR2 is not compatible on a DDR-supported system... Likewise DDR is not compatible to a DDR2-supported system...

When technology advances and older generation of hardware been phased out, it's like a collector's items in the market and prices tend to set higher than newer technology which are been mass produced...

Oic...means i cant upgrade my laptop ram using DDR2? DDR2 is cheaper. I wish to buy it instead of DDR1. Can it work as well? Not compatiable = doesnt work at all or can try?

I see...sad man. Something that is newer and better is actually cheaper than something older and lousier. what an irony.

Answer to all questions, No.

In order to upgrade your laptop RAM, you will need to upgrade your motherboard as well.

Not compatible means it won't work at all. You can try, but I can guarantee you that you need to buy a new motherboard after trying.

"DDR2 DIMMs are not backwards compatible with DDR DIMMs. The notch on DDR2 DIMMs is in a different position than DDR DIMMs, and the pin density is slightly higher than DDR DIMMs. DDR2 is a 240-pin module, DDR is a 184-pin module."

The recent drop in prices of DDR2 1GB sticks is due to excess supply. It had reached the low of $46 per 1GB stick about a month ago and is on its way back liao to $51~$56. Laughing

The drop in prices certainly had nothing to do with technology advancement *coughs* so we're (DDR2 users) just being lucky, and not you being unlucky.

In the same manner, as DDR sticks are no longer in production, diminishing stocks can only mean some spike in the prices as they become a rarity, up to a point where there is no demand from ppl to buy DDR cos it no longer justfies the price.

now bobian liao…have to play game on my sister’s 3gb ddr2 laptop liao. My old laptop cannot make it, cannot upgrade also so expensive.

3gb?! Laughing

I would not really agree that DDR (or 'DDR1') is lousier. I still prefer the higher latency of 2.5 ~3.0 DDR rams have as compared to the 4 ~5 from the DDR2s. The increase in speed at the sacrifice of latency is inevitable nonetheless.

2gb + 1gb = 3gb
