    Default A very big problemwith my RAM module

    Hi there,
    I recently bought a new RAM memory module to upgrade my PC it's a 512 MB at @400Mhz DDR
    Here are some details: it's from Elixir,it's the model M2Y51264DS8HC3G-5T.
    I insert it in the socket and when I start the PC it doesn't load the BIOS and Windows...
    My motherboard is an ASUS K8V-XSE and it's compatible with the RAm I bought,and yes it suports up to 1024 MB of ram.
    Here are some features of the RAM I've bought:
    184 Dual In-Line Memory Module (DIMM)

    Unbuffered DDR DIMM based on 256M bit die C device, organized as either 32Mx8 or 16Mx16


    Latency 3

    Clock Frequency 200 MHz

    Clock Cycle 5 ns

    DQ Burst Frequency 400 MHz

    Intended for 166 and 200 MHz applications

    Inputs and outputs are SSTL-2 compatible

    VDD = VDDQ = 2.5V 0.2V (2.6V 0.1V for PC3200)

    SDRAMs have 4 internal banks for concurrent operation

    Differential clock inputs

    Data is read or written on both clock edges

    DRAM DLL aligns DQ and DQS transitions with clock transitions
    Address and control signals are fully synchronous to positive clock edge

    Programmable Operation:

    Burst Type: Sequential or Interleave

    Burst Length: 2, 4, 8

    Operation: Burst Read and Write

    Auto Refresh (CBR) and Self Refresh Modes

    Automatic and controlled precharge commands

    7.8 ms Max. Average Periodic Refresh Interval

    Serial Presence Detect EEPROM

    Gold contacts

    SDRAMs are packaged in TSOP packages

    RoHS Compliance: M2Y51264DS8HC3G and M2Y25664DS88C3G


    Part Number: M2Y51264DS8HC3G-5T

    Organization: 64Mx64

    Speed: 3-3-3, 200MHz (5ns @ CL = 3)

    Power: 2.6V

    And here are some features of the Ram I have

    Memory Module Properties
    Module Name Kingmax MPXC22F-38KT3R-FNA
    Serial Number None

    Memory Speed PC3200 (200 MHz)
    Module Width 64 bit
    Module Voltage SSTL 2.5
    Error Detection Method None
    Refresh Rate Reduced (7.8 us), Self-Refresh

    Memory Timings
    @ 200 MHz 2.5-3-3-7 (CL-RCD-RP-RAS)
    @ 133 MHz 2.0-2-2-5 (CL-RCD-RP-RAS)

    Memory Module Features
    Early RAS# Precharge Not Supported
    Auto-Precharge Not Supported
    Precharge All Not Supported
    Write1/Read Burst Not Supported
    Buffered Address/Control Inputs Not Supported
    Registered Address/Control Inputs Not Supported
    On-Card PLL (Clock) Not Supported
    Buffered DQMB Inputs Not Supported
    Registered DQMB Inputs Not Supported
    Differential Clock Input Supported
    Redundant Row Address Not Supported

    Memory Module Manufacturer
    Company Name Kingmax Inc.
    Product Information <!-- m --><!-- m -->

    I've tried everything and is not working.
    I've tried to put only the new module in,without the old one and still nothing,It just wont load anything,do anithing as if the PC is off,but the fans are working everything is working but it just wont load the Bios and the Windows.Oh...and my Bios is up to date.
    Someone said to me that my old Ram needs 2.5 volts and my new one 2.6 volts.
    This may be the problem?
    In this case how do I change my voltage settings?

    I thank you for your time

    Yeah you need to know the voltage of your new ram and go into the BIOS and set it to that, and be sure this amount is not too much and ends up killing your old ram!!! If so, you are not going to be able to use them together.

    If you have a OEM system, such as Dell, HP or something like that you are likely not going to have any options like this to change in the BIOS so you will need to return that ram and by proper ram with the correct voltages. I say this because I know Asus boards used to be used in some older OEM machines, if yours is not one then ignore this comment and find your overclock area in your BIOS and adjust the voltages
