Re: Question about RAM type

Your best bet is to get the info from www.crucial.com They guarantee their
modules.

Thank everyone very much for suggestions
If I install DDR 3 1333 into my motherboard, will it switch down to DDR
333
mode?
Or Do I have to use DDR type only for my motherboard? and cannot use DDR2
or
DDR3.
Do you have any suggestions?
Thank everyone very much for suggestions

Do you mean that if I purchase DDR 400 instead of DDR 333, then I will
get
DDR 200 performance, because it switches from 400 into 200 and skipping
333?
Thank everyone very much for any suggestions

It means a stick of DDR400 RAM, can be used like this -

Install in... Runs at...

DDR400 computer DDR400
DDR333 computer DDR333
DDR266 computer DDR266
DDR200 computer DDR200

It can be used for any of the slower speed applications.
The BIOS will adjust the timing settings, for each
of those speeds. That means the BIOS will work out the
correct value of CAS latency setting, depending on the
memory speed setting being use.

You have nothing to worry about. If you buy the DDR400 memory,
and use it in a DDR333 application, it will run at DDR333.

If you use the BIOS, to select other memory speed settings,
the RAM will also support those.

There is only one situation and motherboard I can think of, that
is an exception to the rule. There is a certain motherboard,
which has a defective BIOS design. The hardware is only
capable of running at DDR333. If a stick of DDR400 is installed,
the BIOS tries to run it at DDR400 (mistake!) and the computer
crashes. For that particular computer, and assuming the BIOS has not
be corrected by now, you buy DDR333 memory only, to fix
the BIOS bug. So buying slower memory, is used to compensate
(work around) a BIOS bug. If you install DDR333 (PC2700) memory
on that motherboard, it will run it at DDR333, and then
the hardware is stable.

Most BIOS are bug free, when considering this issue, so there
is no reason for concern.
