SDRAM TO DDR

[Roger]

Help please,

My OS is XP Pro SP2 my board is ECS 62-0206-001131-00101111-040201
SIS735 K7S5A. I have been running on Sdram 512 133 MHz but are changing to
DDR 184 pin 266MHz. I removed SDRAM from board and inserted the new DDR 2
sticks of 512mb this would give me the board max fitted of 1GB. When I
booted back up it appeared not to recognize them it was searching as my both
CD & DVD lights kept coming on. I thought that system would pick them up as
if I had changed the old SDRAM. Have I got to go into the bios to cause it
to recognize these two new DDR slots which are alongside my SDRAM slots. All
help would be gratefully received.

Did you get DDR or DDR2 memory sticks? Your motherboard seems to be
an older motherboard (since it can use SDRAM) and may only accept the
true DDR RAM (scarce) instead of the DDR2 (widely available.) Even
though these two RAM technology might use the same RAM slots, they
have a special control chip that is read by most motherboards.

I would head over to www.kingston.com and check the possible RAM
options with their RAM configurator web pages.

DDR2 memory CANNOT be used on a board that supports DDR memory.

Exchange what you have bought for two DDR 512mb modules..

 

[Peter Foldes]

You cannot use DDR 2 when the MOBO was designed for and with DDR. It just does not
work.

Hi Roger,

Googled your motherboard and found a lot of reviews on your motherboard but
none mentioned any problems using "DDR" ram or
the need to make any changes to the BIOS.
Note, I'm assuming your are using DDR and not DDR2 as they are not
compatible and DDR2 will not fit in a DDR slot.

First thing to check is does your monitor display a BIOS report which should
include the amount of memory when you boot?
If it does then try running Memtest86+, this runs from a boot disk or CD and
should eliminate or confirm if your ram is bad.
Let it run for as long as you can, 2,4,6,8 or more hours, if no errors by
then your ram is OK.
See: http://www.memtest.org/

If you see no memory listed when you boot, remove the DDR ram, insert your
old memory and then go to:
http://www.crucial.com/
and use their "Memory Advisor tool".

I don't see anything on the motherboard to enable one type of
memory over the other. Try the new memory one stick at a time and
see if it is detected that way. Also test that the old memory
still works.

One kind of memory runs at 2.5V and the other at 3.3V. There
is probably onboard regulation of the voltage, and it switches
to one of those values, based on detecting RAM in the slot.

If there is a problem with the new RAM, such as a short circuit
on the power rail, that could damage something. Which is why
I recommend testing that a single stick of the old RAM works,
before going back and testing the new RAM again.

It wouldn't make sense to trigger that from a BIOS setting,
since the BIOS screen will not appear unless working RAM
is present.

Thank you to all, and must apologize for my typing. They are not DDR2, they
are DDR 266MHz I meant I had two 512 modules They are Samsung brought from
Novatech England. On the module on one label it says RAM-21/51s. they are
correct spec

I did replace my old SDRAM (2) 256 sticks, and all was as normal when
switching main power back on.
But when I tried DDR my screen would not boot from stanby and disc drives
kept searching for a disc ! I have the manual already from sometime back.
This did not mention any special procedure, but appeared to show
instructions when first building unit.
I will also try the site mentioned to check my current memory which appears
to work fine. PLEASE keep your good advice coming which should help me out
of this problems

Disk drives kept searching for what disk?

 

[JS]

Did you check your BIOS, some have the ability to
perform and display the results of a memory/ram test?

Also create a boot floppy using Memtest that I mentioned
earlier.

I don't Know, the lights come on the DVD drive, then CDR then back
again,without any further action or the Monitor remains blank without a boot

I have scanned at The Crucial site and posted here results I have the old
SDRAM at the moment
a.. Maximum Memory Capacity: 1024MB
b.. Currently Installed Memory: 512MB
c.. Available Memory Slots: 0
d.. Number of Banks: 2
e.. Dual Channel Support: No
f.. CPU Manufacturer: AuthenticAMD
g.. CPU Family: AMD Duron(tm) Processor Model 3, Stepping 1
h.. CPU Speed: 896 MHz
i..

Q: Will my system recognize the maximum upgrade?

A: Possibly

How much memory your Windows OS will recognize depends on which version of
Windows you are running. 32-bit versions of Windows will see (and utilize)
only 3GB or 3.5GB. To utilize more memory, install a 64-bit version of your
OS. More information about OS memory maximums can be found at
http://www.crucial.com/kb/answer.aspx?qid=4251.

Additional info to this response. It would not matter which version
of the XP (64 bit or 32 bit) ecause your motherboard has a 1024MB
limited, any size greater that this will cause problems.

Without seeing the motherboard SDRAM / DDR memory slots, on other
motherboards, the IDE cables might block the access to the RAM slots.
Check all internal cable connections.

Also, other possibility is to do a complete BIOS reset: pop out the
BIOS/CMOS battery. This should clear out the BIOS/CMOS settings and
hopefully give access to the new RAM (but you will need to re-do the
CMOS settings.)

There are two options at the Crucial site:
One will scan your PC, which is I believe what you let Crucial do.
The second option is the "Crucial Memory Advisor tool"
which has three step process were you select the
1) Manufacture = Elite Group (ECS)
2) Product Line = Elite Group (ECS) Motherboards
3) Select model = K7S5A
(Note: there are 3 K7S5A listed, you need to select the one that matches
your system)
Click on the "Find it" button.
Scroll down the web page results displayed for system.
You should see DDR memory listed.
Look carefully at the specifications that are listed for the Crucial DDR
memory
and see how it compares to the memory you purchased.

For example:
Part #: CT6464Z335 . DDR PC2700 . CL=2.5
Unbuffered . NON-ECC . DDR333 . 2.5V .
64Meg x 64 . . more details

Most likely from the specs listed above the
2.5V requirement is the most critical as some motherboards
require memory that will operate at a lower voltage.

Try the new memory sticks one at a time and in each of the slots. You may
have a bad one..

Well JS I followed as advised above on crucial and it returned parts as
your example DDR. I checked the spec I have, and details are listed >>
Advert as 266Mhz 184 pin 512 MB PC 2100 DDR Ram 2.5v 2.1GB/sec.

On spec list it showed PC 2100/DDR 266= 133mhz/266mhz = Bandwidth of 2.128
GB/sec.

I tried them singular and they did not work. I contacted Novatech Tech dept
they looked at motherboard Manual for mine and could not understand why they
did not work, as it should have been Auto pick up. I have to return them
for refund.
I quoted info from Crucial search on my unit and he said that info did not
match what the Manual quoted, as they quote PC2700 which is higher !

Where do I go from here to get a "simple" update to DDR for my board but not
having to pay through the nose for memory.

Kingston is generally accepted as a top quality memory maker. They
usually have huge R&D in the development of RAM.

Crucial also makes their own RAM.

 

[JS]

The PC2700 memory is faster but this should not be an issue
as 2700 is the max speed and should work just fine a slower
speeds.

Two of my computers both have memory that is rated
faster than the computers require and I have no memory

that this board is sensitive to make of memory, and they believe that ECs
recommends Kingston, but one post said they had used crucial with success
but they are far between with success results. Has anyone sorted this
problem before I buy memory again.

Kingston is generally accepted as a top quality memory maker.  They
usually have huge R&D in the development of RAM.

Crucial also makes their own RAM.

Not every motherboard that was originally designed for a "lower speed"
DDR RAM module can also accept the higher speed modules. Depending
on the version of the BIOS installed on the motherboard, this may
work. In my experiense, ECS motherboard have always been "difficult"
using RAM out of the "expected" specification. Since the motherboard
is requiring DDR then DDR should be used.
