Windows Experience Index

Hi

I have windows Vista which had 2Gb of memory.
The index was 5.2, that was the memory score.

I have added another 2Gb.
As its a 32bit OS only 3.5 GB is detected, but when I updated my windows
experience the score went down for 5.2 to 5.

Shouldn't it have gone up?

possibly you did not put in the same speed of memory as you had and the over all speed has been reduced accordingly.

There's a lot of theories as to why this is. What it seems to come to is
many motherboards and some CPUs don't perform as well if you fill all four
DIMM slots. See the following thread for most of the theories on why this
happens.

No. Adding more memory increases the time it takes for memory to be
addressed. Don't put much stock in the WEI, though. Vista will run
things much better with more RAM regardless of the score.

WEI measures throughput, not amount. I had a 5.3 with 4GB. I went up
to 8GB and my WEI dropped to 5.0 All other scores are 5.9, though.

No. The memory score is based on memory throughput, rather than the amount.
However, you will gain more from adding the memory than the actual
throughput on most things.

If the memory you added is not "exactly" the same speed it will add
LATENCY even if it was faster memory. If indeed the memory is
FASTER add it 1st and if slower put it in last.

Latency can also occur do you MB design. Even though the rating
is slightly slower you should still see an increase in system performance
particularly when you run many programs or a few memory hogging
ones.

You might find this discussion of WEI helpful to understanding what the
numbers mean:

The WEI will be the number of the worst device on your system. It won't
give you any credit at all for all the good stuff. Mine is down because I
only have a few hundred GB of disk space, not a quadzillion. Everything
else is 5.9, but the disk brings it to 5.2.

The disk measurement is a measurement of throughput not free space. The WEI
is not about creating a number to brag about but to point out where the
bottleneck is so you will have an idea on what would be the best upgrade to
a system.

Also, you may have lost dual channel memory performance, depending on
the type of RAM you installed.
