Another seemingly noobie question.

I stand by my very generalized statement. However, as with all
generalizations, specifically you can always find situations where they
don't apply.

Yes, all generalizations are false, including this one (a famous
quotation, but I forgot who first said it).

But I don't agree with your generalization at all. There's my extreme
example above and at the other end of the scale, here's another: if
you are a typical user doing e-mail, web browsing and a little word
processing (my wife, for example), you wouldn't be able to tell the
difference between 2GB and 16GB.

OK--you haven't, but many other people have.

Highly doubtful, Ken. In fact, it's simply untrue.

Suffice it to say that I completely disagree with you. But I won't
argue--end of thread for me.

Hi, Char.

When I built my current rig in 2006, to run Vista RTM, I ordered the
components from NewEgg: EPoX MF570sli mobo/AMD Athlon 64 X2 CPU/2 GB OCZ
PC-6400 SDRAM. EPoX has gone out of business, but this mobo is still
running strong. (Graphics pulls my WEI down to 4.6, but CPU gets 5.7 and
RAM 7.1.)

That 2 GB original RAM ran fine but I wanted more, so I ordered an
additional 2 GB from NewEgg a year later. Identical to the original pair of
DIMMs. Ran fine with 4 GB for about 6 months. Then I started to get BSODs.
After a LOT of testing, my local repair tech and I identified one of the new
pair as questionable. I contacted OCZ. They gave me an RMA for BOTH of the
new sticks. The OCZ tech said they want to replace them in pairs, to be
SURE they match. The new pair they sent have been perfect for over a year
now.

So, even a matched pair from the same maker, same model and everything, CAN
fail to work together properly. I'm not techie, so I can't begin to explain
it. All I know is what I experienced. YMMV.

Tosh. Mime performs perfectly well on only 2GB...

The rule of thumb (for general use) I've used for years with
Windows, and it has served me pretty well, is to take the RAM
minimum recommended by Microsoft and double it.



To take a single example, Microsoft's minimum for Windows XP was
64MB. Have you ever tried running it with 128MB? Unless you do little
more than play solitaire, 128MB isn't enough for anyone. Almost
everyone needs at least 256MB, and depending on what apps they run,
many people need more.

[snip]

MS "recommends" 128MB for XP Home even though they say "at least" 64MB.

I can't find the web pages now, but I've seen both those numbers
*recommended*. They weren't always consistent.

Did a Yahoo search "windows xp hardware requirements". The above link
was first on the list.

Tip: always suspect bad RAM when encountering random BSOD's. Run
Memtest86+ through at least one complete cycle.

Yes, that's normal, and they do that to ensure best performance, not
because failing to do so will result in further instability. It's easy
to reach the wrong conclusion, but now you know.

So, even a matched pair from the same maker, same model and everything, CAN
fail to work together properly. I'm not techie, so I can't begin to explain
it.

No need. I've been building, repairing, and upgrading PC's as a side
business since 1986, so I'm pretty familiar with the situation.

As long as you stay with the right type of memory, DIMM, DRAM, DDRx,
etc.), and the right number of pins to match your mobo RAM sockets,
you can mix and match memory modules from different manufacturers,
different densities, and different speeds. When using different
speeds, memory access drops down to the slowest supported speed,
naturally.

All I know is what I experienced. YMMV.

That's ok, sharing experiences is what it's all about.

I don't know where the myth of not being able to mix different memory
modules came from, but I've been hearing it on and off for as long as
I can remember. I just figured I'd do my part to help put it to rest.
