RAM upgrade issue

Hello Walt now that machine does support 4GB RAM and I don't think you can alter the memoery speeds witha BIOS thta old I stand to be corrected of course.

What I suggest you do is put in the old RAM which I am guessing the machien came with and find out the timings etc using this
Using HW Info
PART A:
You can test the volts on the PSU with HW Info HWiNFO, HWiNFO32/64 - Download < download the right bit version and close the right hand window select Sensors and scroll down to the power section where you will see what the volts are doing see my pic. In my pic the section (Nuvoton) with VBATT as a dead give away you are in the section for the rail voltages. There are other section titles and one that pops up often is ITE (sometimes the usual one for Gigabyte boards)
Now the voltage on the different rails have to be within 5% =+/- of what is required or the machine will not work properly if at all.
Limits +/-
12v = 11.4 – 12.6v
5v = 4.74 – 5.25v
3.3v = 3.135 – 3.465v
The Power good signal voltage at pin 8 on the 24 pin plug (grey cable) should be the same as the 5v rail reading/s
See this for the rail voltage info
PSUs 101: A Detailed Look Into Power Supplies (Section 2.)
The original right hand window shows the machine running and is handy for that but for looking at the components in some detail close it and use the main left hand side panel
FOR OTHER COMPONENTS
PART B:
Open each small square with + in it on the section the components are in and then click on the individual component/s (it will highlight in blue) - in the right hand side will appear all sorts of details including brands speeds and other essential info that particular device. See pic for example.

Use PART B: and scroll down the right hand side panel to find exactly what they are. See pic of mine you need only highlight the sticks to find the speeds and timings

After that I would be inclined to get just one stick - 4GB RAM or at very least a matched pair (2x2GB) because that way it avoids any discrepancies in unmatched / different brand RAM

If you want some really good advice try Tradesman at here Welcome to the G.SKILL TECH FORUM - I do like G Skill as well too but he can advise you far more than I.

I tried the program but was unable to find any voltage data.

I went to CPU-Z and found some answers on the voltage and frequency. Some snaps on Word doc looks like max freq is set at 333 MHz and 1.8 volts so the new RAM won't work.

DDR2 means Double Data Rate, version 2. It means that it functions on a double frequency rate. So the clock is 333,33 MHz but the memory works a the double of the clock frequency, 667 MHz. The problem of your new memory must be related to manufacture type or latency. Try a DDR2 800. I'm quite sure it will work.

There is a YouTube on how the CMOS and RAM work together which says other.

Ranger, you're absolutely correct. I've already correct my post. Thank you.

Some laptops are sensitive to the kind of memory chips in use, single side x double side, latency etc. I have just replaced 2x1G DDR2 667 on a Sony laptop with 2x2G DDR2 800 (PC6400) and it's working fine. Are you able to try 2x2G DDR2 800 (PC6400)?

I went to the computer store today and tried 2 brands of 2X2G of DDR2 800 (PC6400) and the same
issue of no booting occurred.

Tried the DDR2 800 today with 2 different manufactures neither worked.
