Does anyone know of a web-site that details the pros and cons of ECC
RAM?

Thanks.

I found the following website by searching on google for ECC Pros and Cons
(the and will be ignored, do not use quotations marks)

http://www.pcguide.com/ref/ram/errPros-c.html

I'm not trying to be rude, and this is to everyone (because I've seen
something like this before). Perhaps you could look around a bit before
running to others for help?

What is real cool about the original post is that YOU responded with a very
interesting link that I am going to read tonite & will learn about something
I hadn't thought about before.

My thanks to both of you. This is a discussion group!

I agree 150% with you, also sometimes, you can look for websites and do
not find one that is any good, but someone else may have found a good
one to explain what you want to know.

ECC stands for "Error Correcting Code". Mostly used in servers and
workstations. ECC can detect and correct for single bit errors and detect
greater errors. The chipset of the motherboard must support this
functionality. Most consumer grade motherboards do not support ECC.
Registered memory uses a register to delay the flow of data to the RAM.
Common in very large memory modules like 1GB. Again mostly for servers and
workstations.
 
Tad slower than regular and not at all necessary in a home unit, Servers use
ECC due to the large amounts of memory and data which increase the odds of
an error showing up, most are crunching 24 a day.

I read on THG or Anadtech that buffered and ECC is recommended for 512 and
larger modules for all PCs if you can afford it.
 
Ha, I did look around a bit, but I didn't think to use the words
"pros" and "cons" until I posted the message here. The words I
searched for were "ECC non-ECC worth it?" - didn't come back with
much. Mostly shops selling different types of RAM.

I looked but (embarrasingly) I can't find that reference. I'll keep
looking
for it and post it when / if I find it again.

No problem. I'll go hunting on the Internet to see if I see a good
site comparing the two RAM types.

ECC can and (in the case of memory) is used to cover bad design.

To aid in understanding.
For hard disks, a single bit is "indeterminate", and specs allow
as many as 10 or 11 single missing bits in a row as "correctable".
- ECC is fundamental to the read/write technology.

In serial communications the "theoretical" limit is 2 dedicated
1220bps channels over standard phone lines.
But 38400bps is achieved by a combination of asymetrical send
receive channels, and "quadplexing" (or something like that.)
synchonizing clocks, and ECC to hold it all together.
- It works, most of the time.
(Blame the phone co when it doesn't :-)
- Smiley because it's more likely the crappy modem your ISP is using.
- Or the throttling of the bandwidth he's allowing you.

Memory is the most reliable best understood techology in use today.
Guardbands assure that it remains so under normal temperature
variations, and worse case timing considerations.
Overclocking messes with the clocking of memory.
Doit and ECC becomes required to handle the errors.
Combine it with virtual memory nonsense, and you deserve what you get.
- Confused ! :)


You are, but, Thanks I may just do that.

Me too.

----- My best advice -----
If it ain't broke don't fix it.
New ain't better.
If you run into an old lady, run over her again.
Cause she won't quit bitching till make her young again.
