Default RAN 1.35v vs 1.5v

First answer is: As far as I know, the voltage of the board in the bios
shows the max voltage that can be drawn by the hardware, so if the RAM
only draws 1.35, that's all it should use. I'm not 100% though so this
is purely a comment, not an answer.


You don't "draw" voltage, you draw current. Voltage is supplied.

That's for sure, it's not an answer, because his first sentence shows he
doesn't know how electricity works. bg

This is it, but it's not exactly the same as the Samsung that's in there
now. Which is more important? :-(


Well, you know that what's in there works. The above should work based on the
specs, and I'd be surprised if it didn't. Your choice though. :-)


My choice? I don't know. I left it up to you guys, pretty much, and
your answer is pretty convincing.

LOL, yes it's my choice and I'm happy with your answer, and the others.
Thanks. I ordered the matching dimms.

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.
1.35V DIMMs run in a 1.5V motherboard.

There should be a FAQ with the details around somewhere.

https://superuser.com/questions/5641...y-or-overclock


First answer is: As far as I know, the voltage of the board in the bios
shows the max voltage that can be drawn by the hardware, so if the RAM
only draws 1.35, that's all it should use. I'm not 100% though so this
is purely a comment, not an answer.


If your machine uses SODIMMs, I must have selected the wrong
item from the Crucial list.


No, it doesn't us SODIMMs. The two smaller versions of the same name do,
but the my SFF and the tower version use dimms.

If you have part numbers on the existing modules and you're
happy with them, then that's likely just as good of a
choice as anything else. If you got "fancy" products with
low CAS, they wouldn't help, because the slowest memory
in the machine determine the speed choice made by the BIOS.


Okay, so there's no point in looking for lower CAS. Someone suggested
buying 4 8's but I don't want to spend extra money. (The first machine
I bought, the one that didnt' work and was the wrong model too, had all
4 slots filled with 4's, and I thought that might be the standard in
refurbishing, but this one has 2 8's .)

But if supplies were limited (like the Crucial being out of
stock), I was looking around to see what could be fitted
from the existing pool of product.

I'm really surprised you can find branded Samsung DIMMs/SODIMMs.
Samsung sells product more to businesses than to end users.


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.)

So I got the Samsung from them via Amazon.
https://en.wikipedia.org/wiki/Dataram although the info on this page
stops at about 2011.
http://memory.dataram.com/ Their webpage is in English, French, German,
and Japanese!

The SPD table shows what the DIMM expects in terms of voltage.
The SPD chip receives power right away, and the BIOS reads the SPD.
The BIOS "turns on" the VDIMM regulator, only when it has
determined what the strategy is. So RAM is "commissioned"


This is all very clever.

by the BIOS POST process - and some of the BIOS code
runs without RAM for storage, and variables are stored
in CPU internal registers.

If the BIOS is unhappy with what it reads in the SPD table,
it will "beep". And occasionally a poster will post a question
about a BIOS that is beeping, when it should not. And in some
cases, it tries to match fields in the SPD that are
"don't cares". That means poorly prepared SPD table
contents, can result in surprises for users. One DIMM even
had the wrong SPD chip soldered to it :-) Clever.


LOL Thanks.

Paul

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.

You know there are more nuances than that.

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.

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

I don't know anything for a fact about that, but I think I get less mail
than I used to, and my front door is 30-40 feet from the path the
mailman would take if he didn't go to my house, times 2 to return.

And I think they've stopped delivering my mail until several pieces
build up.

Worse than that I get a weekly newspaper in the mail and it came either
on Friday or Saturday for years, Now they come out of order and always
late, a week I got two on the same day, and yesterday I got an issue
from December, and that's not unusually late.

Plus I never got my emission inspections letter. The email about it
came in December, and to get excused because I dont' drive more than
5000 miles a year and I'm over 70, I have to file a form. But the email
didn't include the form. The letter would have. It did 2 years ago.
And the web didn't have a copy either.

So I wrote them a letter explaining all this in the top 1/4 of the page
and the rest I copied the format of a different form, with changes to be
the form I needed, asking for them to accept that or send me the form.

I sent that quite a while ago and haven't heard back, and last time
after I sent the form I heard back in less than 2 weeks. The virus
might have a lot to do with this last thing.
