I'm posting to get some advice about REAL bus speeds.
I want to know how much my chipset and processor would benefit from
different memory. The trouble is that I have become confused by
"effective bus speed" and "actual bus speed" and "nominal bus speed"
and so on.
As you may be tired of hearing (!) I am running a Duron Applebred
1800 in a Via 266 mobo made by Syntax with 768 KB of 133 SD-RAM. The
BIOS is by Phoenix. The CPU temp under load is ok at 44 degrees C.
The manual for the mobo is available at http://tinyurl.com/9rc5d
(OR http://188.8.131.52/support/SyntaxDownloads/download_manuals /
My Syntax mobo can run either SD-RAM or DDR. I am thinking that I
could upgrade the 768MB of 133 SD-RAM to DDR in order to get an
increase in performnce.
Then later on this year, I can build a faster PC using all new parts
except for the DDR which I could take from the existing Snytax mobo.
(I would put the slower SD-RAM back into the Syntax mobo to create a
basic PC.) I do not want to spend more money than I have to as I am
on a budget.
QUESTION ONE. What speed DIMM memory would work well with my
Via266/Duron1800 and yet still be good to use with a faster processor
later this year which will probably be a mid-power socket 939 (and
some mobo chipset which I haven't decided on yet)? Is PC2700 too
QUESTION TWO. How fast does the bus on my mobo/cpu actually run
these devices at:
(a) the "133/266 MHz FSB" on the cpu
(b) the bus on 133 MHz SD-RAM
(c) suitable DDR in Q.1 (PC2700 ??)
(d) the PCI bus.
Thank you guys.
