Default Question about SDR memory vs DDR memory

I currently have 1 gig of SDR PC133 memory. Will I experience a significant
speed increase if I go to 1 gig of DDR 433 memory? How would I know if my
motherboard can support it?

I know very little about memory, so please excuse what may be an obvious
question to everyone out there.

If you are running sdram chips you cannot put DDR ram into that
motherboard.

They require different sockets.

SDR and DDR are incompatible. You'll need a new motherboard and
processor if you want to use DDR.

There are some very common motherboards that can use either PC133
or DDR memory, because they have both types of slots on the
board. Both types cannot be used at the same time though, it's
one or the other. You make no mention of the specific
motherboard make/model so we cannot know if this is the
situation. Consult your motherboard manual for memory type
supported.

IF your motherboard supports DDR memory (PC1600, PC2100, etc)
then you should be able to use DDR433, most often called PC3500.

My motherboard has 2 sockets for SDR and 2 sockets for DDR.

You're the second person to tell me this. Do you guys REALLY think I'd ask
this if my motherboard didn't support DDR? I have 2 slots for SDR and 2
slots for DDR.

Then go to crucial.com like a good boy and use the memory finder for
your motherboard.

433 will just be wasted on an old mb. You probably will see some
improvement doing to double data rate, at whatever speed.

After my last reply, I located my motherboard's manual. I supports the
PC2100 DDR, so I bought 2 gigs of the 233mhz stuff, the max my motherboard
can use.

When you use 'it' instead of the correct noun, you'll get ambiguous
replies. We thought you were asking if yer mb supported DDR memory.

Use nouns whenever you can...instead of pronouns...especially in
technical questions.


The way I read it, I think it's obvious that my motherboard has DDR slots.
Why else would I ask about a speed increase SDR vs DDR? Based on the fact
that my motherboard has DDR slots, it's apparent that I was asking how I
would find out if my motherboard supported the 433 memory. Since I posted
this message, I found my motherboard's manual, found that it can support up
to 2 gig of the DDR 266 and I've purchased 2 gig of DDR 266... Thank you for
the replies, though.

Because you know very little about memory?...and didn't know that the
two are not interchangeable? At any rate, that's what some of us
assumed.


Tsk tsk. There's that "A" word... ya know what that makes U and Me, right?
