Speedfan Info question

[John Latter]

Hi,

I've just upgraded my system memory from 512 to 768 MB (256 in slot 0
& 512 in slot 1)

Speedfan Info gives:

Scanning SMBus at $5000...

Decoding DIMM #0
Memory type is DDR
Module Rows : 2
Levels : 2.5V
Parity : NO PARITY
Refresh Rate : 15.62us
Total Size : 256MB

Decoding DIMM #1
Memory type is DDR
Module Rows : 2
Levels : 2.5V
Parity : NO PARITY
Refresh Rate : 7.8us
Total Size : 512MB

The refresh rate is different, I'm having no problems running the new
memory, and I made sure the new 512 chip had the same specs as the
original. This is confirmed by cpu-z which gives identical specs for
the two modules (CAS# RAS# Tras# etc - not that I know what they
mean!).

Does anyone know why the refresh rates are different & what the
significance is? I always thought that the refresh rate of the
original chips was 7.8us but I'm not 100% sure...

Crikey - I'm going to have to read that in the morning If I'm gonna
stand any chance of understanding it!

But thanks for the link

Would it make any difference if I swapped the 2 chips over - do I need
to? Are things ok as they are?

I don't know much at all

In the grand scheme of things, it's not going to matter at all. Happy
reading.
