RAM Results Don't Make Sense

Recommended Posts

I tested two rigs:

1. DDR 1.5GB

1527 MB System RAM (Score: 89)
- RAM Speed: 1723 MB/s

2. DDR2 3GB

3071 MB System RAM (Score: 88)
- RAM Speed: 2287 MB/s

Why does twice as as much DDR2, at a faster speed, score lower than DDR?

Thanks for any input,

ps. Here's the whole systems:

Thanks for posting that. I think you found an edge case/bug with our score algorithm. I will look into correcting it with the next version.

Either your not using Pairs of memory sticks, or the memory sticks are not identical. DDR is "Double Data Rate". To achieve max speed you need need pairs, and all of the ram needs to be compatible. Ideally, identical as to mfg, speed, and characteristics.

That said, I've added unmatched ram to a system, had the scores go down, but the user experience improve because of less HDD delays.
