paging the computer cognisti ...

I have a PC needing more RAM, it takes DDR 400 and has 2 blue and 2
black memory sockets, alternating blue/black blue/black.

I am proposing to install 2 off 1 GB modules ... which sockets
should I put them in ?

Thanks,

The two blue sockets should be populated first.
Then the two black.
(Assuming the chipset features a dual channel memory controller).

 

Hi,

Thanks for the reply - not sure whether it has a dual channel memory
controller, but if I just fit two modules in the blue
sockets I guess it will be OK - at the moment there is a 1GB module
at 2700 and a 256 MB module at 3200 which seems
to run fine and memory reported is 1.25 GB - so may I assume the
machine is OK with 3200 DDR 400MHz modules ?

Thanks

Nick

 

Just discovered it does NOT have "Dual Channel Support" .
If I got it wrong would it damage anything or just run slower ?

Thanks again,
Nick

 

It will explode, hitting you with thousands of razor-sharp fragments of
memory chips.

Be careful, eh?

Single core or duo core?

Anyway, you can't hurt it. Stick them in there. Turn it on. If it
don't boot, try a different config.

 

It seems not having dual channel support means you can put in
different memory card sizes, which is why this is working OK,
but the other one I am swapping around with does have dual channel
support, so needs memory cards of the same size.

Yeah, anything that runs duos (either multiple CPUs or multi cores)
will want everything paired. But if you know physically how much you
are putting in there and it appears correctly on boot as recognised,
you are pretty much right. If it don't like it, you will get a
sequence of beeps as the pooter tries to boot and no opening screen.

 

Yeah, anything that runs duos (either multiple CPUs or multi

Thanks for that - a 20 minute job turned into thinking about
updating all, so all
pcs have been opened, inspected, memory swapped about where possible
and new modules ordered according to wishes/how fast it needs to
work.

So should be set up in a few days

Thanks to all for the suggestions / info

Huh, what are you wittering on about ?

Dual Channel Memory first appeared on the 865/875 chipset in 2003 when we
transitioned from DDR333 -> 400.

Nowt to to with Dual Core / Core Duo / Single Core which are processor
technologies.

Yeah - but that defines whether the RAM has to be paired or not. That
was what I was getting at.

 

Yes it does, no it doesn't. Whatever, as I said on that reply to him,
if the pooter recognises full RAM on boot then it is fine. Dual CPUs
and dual cores tend to like paired RAM. If he ain't running any of
them then just shove it in there and turn it on. It's not going to
turn the universe into soup if it is wrong.

 

No. The apostrophe-s is only omitted when the noun is in the plural. A
final 's' in a singular substantive does not change its use.

I still think KG is confusing dual channel / dual core.

 

* ! & £ $ eh ? Wot ?

Thanks guys - sorry if I have started a discussion / debate /
argument - it's all a bit above me anyway, but what
I think I am reading is that if I stick a pair of same size modules
in the two blue slots, all will be fine...

Thanks

I wasn't confusing it, but had been informed that dual core required
paired RAM. But as most of my machines have been dual CPU as well, I
guess I've just always paired RAM.

I stand corrected.

 

Which I admitted afterwards. Sorry for being human. As I said, most of
my PCs require paired RAM and I was under the impression that dual
cores required it as well. But as the only dual cores have been dual
CPUs as well, I wasn't paying enough attention. So shoot me . . .
