i want to upgrade my memory.
i have two slots, one with 256 Mb DDR at 333 Mhz and the other is vacant.
i searched the internet for prices of new memory sticks and found out there
is another component of the memory specifications: "C1", "C2" and "C3".
i noticed that the higher the C number - the higher the memory stick price.
i searched for size and speed information on my currently available memory
using AIDA32, Belarc Advisor and Everest.
none of them mentions the C number.
please tell me what it describes/reffers to and if it is important to select
the right one when buying another memory stick.
also, how do i find out the maximum amount of memory supported by my
motherboard.

Go to the web site of a RAM manufacturer - e.g. - www.crucial.com - and use
their RAM selector to find the exact RAM that is compatible with your make
and model of computer.

Do you think you cross-posted to enough newsgroups?

Surely the meaning of these numbers is explained in the manual for your
computer. I can't say that I have ever heard of such numbers or anything
resembling the quoted numbers.

what about "CL1", "CL2", "CL2.5" and "CL3" ?

You should be careful what you ask for.. this is an exerpt from 'Kingston'
site.. I thought about letting you read through the entire article.. you
might still want to do so, as you seem inclined to want to know all there is
about memory..

CAS LATENCY

The term CAS latency refers to the number of clock cycles it takes before a
column can be addressed on the DRAM chip. Latency is a measure of delay, so
a "CL2" CAS latency factor indicates a two-clock cycle delay, and a "CL3"
latency factor indicates a three-clock cycle delay. When SDRAM chips first
came out, it was difficult to produce chips with a CAS latency factor as low
as CL2. And although some specifications called for CL2, many modules worked
fine at a CAS latency factor of CL3.

if i asked it was because i had no idea,
and this way more ppl from several groups saw my question so i would
recsieve ansers more quickly.

I won't speak for Bob. Here's why it disturbs me: It is unnecessary to post
to so many newsgroups, and doing so is considered rude in the usenet
community. Choose the newsgroup best suited to your question.

that's not true. i have windows xp pro. i wanted the reply i get about the
cl think in memory to be suitable for my os.

WRONG, XP will only use it, IF it matches the motherboard properly. XP
has absolutely NOTHING to do with the memory specification. XP ONLY
specifies the MINIMUM amount required to install and the MAXIMUM amount
it will use.

ok, so thanks to your kindness and friendliness, i now know that it has more
to do with my motherboard than my OS. how do i figure out which "CL" do i
buy for my motherboard? as i mentioned earlier, Belarc Advisor, Aida32 and
Everest only give me minimal information about my existing memory stick.
they mention nothing about the CL. is there a certain range of memory speeds
that determine the CL number? the one i have is 256 MB 333MHz. does this
mean i need a cl1? (wild guess)
thank you for your patience and good will!
