I wanted to get more RAM for my newly-acquired PC

Entering the make and model, HP EliteDesk 800 G1 Small Form Factor

Crucial suggests only CT2K102464BD160B

DDR3 PC3-12800 • CL=11 • Unbuffered • NON-ECC • DDR3-1600 • 1.35V •
1024Meg x 64 • $76 even cheaper at NewEgg,


Kingston suggests only KCP316ND8/8

Specs: DDR3, 1600MHz, Non-ECC, CL11, X8, 1.5V, Unbuffered, DIMM,
240-pin, 2R, 4Gbit $98


The items are in different order but the main difference seems to me to
be 1.35v vs 1.5v.

That seems important, right? How can they be different for the same
computer? (I'm not really concerned about price unless they could
sell
it cheaper by making it at the wrong, lower voltage. )

Do I need to look up what the computer puts out? Would one of
these be
overclocked if the computer puts out 1.5v and the other underclocked if
the computer puts out 1.35?

I already have 2 sticks, Do I want to get the same voltage that they
use, whatever that is?


------

Other differences are
Crucial says PC3-12800 but Kingston doesn't include that.

Kingston says X8, 2R, 4Gbit but Crucial doesn't include any of
that.

Does any of that matter?


------

FTR, I only looked at Newegg because Crucial was out of stock. NewEgg
says "Ships from China. Newegg Most customers receive within 10-32
days."

Hmm. At
https://www.newegg.com/crucial-16gb-...82E16820156047

it says sold and shipped by Ram-Store and when you click on 12 New from
$88.46 , it goes to the bottom of the page where they have 12 vendors
selling the same thing. Just like Amazon does it. I only looked at the
first 5 but one is in Hong Kong and "Most customers receive within 4-17
days.". One is in the US and "Most customers receive within 7-9 days",
all except Hong Kong for the same price!! (For Hong Kong and the next 7
the price gets higher.)

But this doesn't matter until I understand the voltage question.


Hi Micky,

Call Kingston tech support and describe the issue to them:

877-546-4786
714-435-2600

Kingston's customer service is something to behold.
Because of it. I only sell their memory, unless they
don't carry what I need. They really, really back
their stuff up.

Thanks. I almost did this but then saw that I had Samsung in there now.
So unless someone tells me I shouldn't, matching the dimms that are
there now is the right thing to do?

SAMSUNG M378B1G73DB0-CK0


My experience is that you should match them


Good. That settles it.

You know there are more nuances than that.


Well, I thought it did.

If Dell sells a 6GB machine, you know right away
it shipped with a 4GB and a 2GB module, and it
left the factory in an unmatched state. The machines
are obviously flexible to some degree, as these non-power-of-two
machines are quite common at retail.

I try not to send people on excessively constrained
missions, if I can help it. FLEX memory capability
has probably been around now for ten years, and lots
of machines can accept, say, 512MB,1GB,2GB,4GB
in the four slots and still work. Is it "optimal" ?
Of course not. But for the average user seeking
an easy upgrade with garbage in the desk drawer,
it'll work. And the Intel caching structure makes
any reduction in memory speed, almost invisible
to these choices. (older AMD, less so)

It's better for the user, if they have a "retail"
motherboard in a home-built machine, as those have
extensive controls (even if I don't know what to
do with all the settings!). It's the Dell and HP
machines, you have to use your intuition as to
what aspects of memory choices will antagonize
the BIOS, or not.


Nuances beyond my ken, but I can tell you didn't say no.

"Strict matching" is a good rule for say, S939.


Aha, https://en.wikipedia.org/wiki/Socket_939

Very interesting.

Hi Micky,

All the machines I build come with way more memory than
the customer will ever use. I just get sticks with the
same part number from the bin next to each other and
have never had a problem. I don't bother buying
"matched" sets.

I have had memory upgrades where I told the the customer
that is was not worth the problems to try to get mismatches
to work. They have always just let me remove the old
ones and install new ones. Memory prices have really
come down.

My main office machine is Fedora 33 running 16 GB of
ECC memory. I have 11 virtual machines. I get away
with running two at a time with not issues. I have
had five running before and it starts to slow a bit,
but I don't run out of memory.

Bought it late Wednesday night,
shipped on Thursday from Princeton, New Jersey, USPS
Via Philadephia, in Baltimore today, Friday, since 8AM,
Probably get it tomorrow.
2 days instead of 11-14.
I'm glad I didnt' pay extra for faster shipping.

I have gotten amazon packages (delivered by USPS) on Sunday. I thought
Sunday delivery cost extra, and I never paid extra for it.

amazon has the volume to determine their own price/delivery structure,
and sunday delivery is not new:

fedex home delivery also delivers every day as of last year:

There is no date on this and Sunday delivery by the USPS is new, and
only exists some places.

Yes,of course. Mark was talking about Fedex.

If I'd known that, I might not have looked! Several places that
google found were out of stock, but as is not uncommon, Amazon had it,
although its sold and shipped by Dataram, a company that's 54 years old
and made ram themselves, and I think they still do. And it's even in
New Jersey so maybe I'll get it a day or two earlier since I'm in
Baltimore. (though it says 14 days. That's okay.)

I did get it today, with the regular mail.

2 days instead of 11-14.

Amazon is indeed delivering quickly usually and on Sunday someetimes,
but just to be clear, this was sold and mailed by Dataram. Though not
from Princeton but from Chalfont, Pa which is about 20 miles north of
the Philly, even closer to Balt than Princeton.
