    RAM data

    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.

    Walt it might need a new download because HW is usually reliable see my pic of my RAM to see how to open it out. Sorry but the wifi on vacation is pretty ordinary right where we are.

    Oh and just in case ypou did it take no notice of the update notice - close it.

    Cmos


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

    CMOS or Complementary-Metal–Oxide–Semiconductor was / is used as memory to store BIOS configuration data. The BIOS program is now stored on EEPROM (Electrically Erasable Programmable Read-Only Memory). The battery is used to keep CMOS BIOS information and clock after power off. Nowadays it uses a 3V coin battery (CR2032). If the clock is working fine, means that the coin battery is OK. The memory function is not affected by BIOS as memory parameters is not reconfigured on BIOS. I'm quite sure that the memory you bought is faulty or isn't compatible with your computer. Try a DDR2 800. I'm quite sure it will work.

    @ Megahertz07. You have stated that the CMOS battery is a CR2032 5V battery. Actually it's a CR2032 3V (3 volt) battery.

    This is not meant as a criticism, but an information correction.

    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.
