Default Computer won't boot up after installing new RAM

Don't forget to use the Crucial on-line analyzer.
Can save you from getting the wrong stuff again!

As a cross check, to help in validating what you
purchase, both the Crucial and Kingston memory
for your PC should have very similar specifications.

Hi JS and Paul

Thank you so much for the valuable information you both gave me.I will get
a new pair of RAM according to the specification you gave me before and i
will get a new power supply because power supply fan is making loud
noises.Thanks again for your help.

I think you just got a bad batch of memory.
Return it ASAP and look for a quality brand
such as Kingston or Crucial.

Hi JS

Thank you for the information you gave me.I guess i got RAM that isn't
working correctly.When i gave you Kingston model KVR800D2N6/1G it was
the
one
i have in my other desktop so it was a mistake.DDR2 wouldn't fit in the
motherboard i mentioned earlier since notch wouldn't fit.Here is what
written
on the sticker of the new RAM that isn't working: EasyPC Technology
1GB
DDR
PC-3200 CT1GD64SH08BL-5T in case you want to make some search.Thank you
so
much for your help.

No the small difference in the values is insignificant and
is actually in favor of the new ram as far as booting.
Also sometimes a BIOS will not accurately read the
memory sticks stated SPD numbers.

Go over the operating voltage specs one more time and if no joy
return the memory to the place you purchased it from and then use the
Crucial Memory Advisor tool posted earlier. If you purchase the memory
the "Advisor" recommends your problems should be solved.

Hi JS

Sorry i couldn't write you before today i was out of the city.I
tried
installing new RAM and i was able to boot and check BIOS like you
told
me
before to compare between old and new RAM values in BIOS.

New RAM
Under Advanced chipset features
Configure DRAM Timing [SPD]
CAS Latency Time 3
Active To Percharge Delay 8
DRAM RAS# to CAS# Delay 4
DRAM RAS# Percharge 4
Refresh Mode Select 7.8us


Old RAM
Configure DRAM Timing [SPD]
CAS Latency Time 3
Active To Perchange Delay 8
DRAM RAS# to CAS# Delay 3
DRAM RAS# Percharge 3
Refresh Mode Select 7.8us

Does that mean they aren't compatible and new RAM won't work with
the
motherboard i have.Please help.Thanks again.

If the Power Supply fan is making uncommon noises
then yes replace it with a unit that at least equal to the
wattage rating on the power supply sticker. Look for
the number of 12V rails and the wattage for each rail.

If you have a 350 Watt power supply now then replace it
with a 450 or 550 watt supply to give you some spare wattage
in case you plan additional upgrades.

Now as to the memory issue, if the computer works fine with
the old memory sticks then you either have defective sticks or
more likely incompatible memory. Try the Crucial Memory
Advisor link: http://www.crucial.com/store/listmfgr.asp?cat=RAM

From what you posted the value of your
"Current CPU Temperature 64C" is way too high especially
if the computer is basically at idle (no load). You may want
to look at a better heatsink and fan plus Arctic Clean 1& 2 to
clean off the old past or pad one your CPU
http://www.arcticsilver.com/arcticlean.htm
and Arctic "Ceramique" for the thermal paste.
http://www.arcticsilver.com/ceramique.htm

Read the instructions carefully on how to remove the old
past/pad from the CPU and the clean it using Artic Clean.
Same for applying the paste for a socket 478 CPU. Do
it properly and you CPU should drop down to about 34C
at idle.

But take care of the memory issue first.
Also check your existing values:
CAS Latency Time 3
Active to Percharge Delay 8
DRAM RAS# to CAS# Delay 3
DRAM RAS# Percharge 3

How do these values compare with your old
and new memory?

Hi JS

I cannot get the computer to boot using 1GB RAM so i have no way

When i pressed on CTRL+F1 it didn't give me anything

Please tell me what i shall i do next.

If i consider getting a new RAM what are the specifications i
should
look
for inorder to be sure it will work with the motherboard i
have.Also
do
you
think changing power supply unit could solve the problem because
lately
it's
Fan make noises not like it used to be.Thanks again

It's sound more and more like M.I.T settings
in your BIOS. What you need to do is only insert
one memory stick, boot and see if you can immediately enter
the BIOS. Do this by "Powering ON the computer and
pressing Del key several time to immediately will allow
you to enter BIOS setup.

If you can select "Load Optimized Defaults", then Save and Exit
the
BIOS.
Then power down, turn off the power supply or remove the power
cord
wait 30 seconds and insert the second memory stick.Power up and
if
see
if
all is well.

If still having problems power down and remove one stick.
Then power up and from the main BIOS Menu enter the "Check PC
Health"
status.
(Page 53 of the motherboard manual)

Next check the "Frequency and Voltage Control"
The "CPU Core voltage" ,
"Memory Frequency (MHz)" and "CPU Host Frequency (MHz)"
Note: Mem Freq number must be equal to or less the Ram Stick
ratings.
(Page 55) Same for memory voltages. If you can change the

After you check and adjust any values if necessary go back to
the
main BIOS menu and press Ctrl+F1, Gigabyte sometime hides
the advanced setting from users. Let me know if Ctrl+F1 brings
up any additional bios settings

Hi JS

Here are the specifications of both new and old RAM

Elixir 256MB DDR-400MHZ , PC3200U-30330
N2DS25680BT-ST
0351.EME03C1201B.120393M.XX.TW


Kingston: 1GB DDR PC-3200
ELPIDA , D5108AGTA-5B-E
CT1GD64SH08BL-5T


I tried installing one stick of 1GB then i booted it worked
normally.Then
when i tried booting again it took around 20 seconds to boot
up.I
tried
booting a third time it didn't boot at all.Now i am using old
RAM.Is
it
a
RAM
problem or is it something with the power supply.Please help.

There is a Elixir Part number, see the web site link below
and use there part numbering scheme, when you post back
the actual part number then I can do a better comparison.
http://www.elixir-memory.com/sup_name_rul_2.asp

Also you Gigabyte motherboard uses "MIT's" technology
which has been know to cause the PC to fail to boot on socket
775
motherboards when you first install new memory, this may or
may
not
be the case with the older sockets 478 motherboards.

The solution is to only install one memory stick and power up
the PC and let the BIOS "learn" the memory requirements
and then after a few successful reboots then install the
second
memory stick.

Hi Everyone

Thank you so much for trying to help me solve the problem i
am
having.

I checked Memory frequency in Bios and here what i found

AGP/PCI/SRC Frequency(MHZ) 66/33/100


Also here is what written on the old RAM which came with
the
computer,Please tell me if it is the same compatible with
the
new
RAM i
bought recently.Now i installed old RAM inorder to be able
to
use
the
computer.

Old RAM : Two sticks of Elixir 256MB DDR-400MHZ, CL3
