    Hi Lsdmeasap,

    first of all thank you for your reply. I tried a lot of variations with the values you suggested me to set. From the highest to the lowest, with every option and so on... but it obviously did not match the correct setting. After every value-change i booted memtest2.11 from CD and it threw errors right from the beginning of the tests. So i first decided to put the RAM back into single channel mode.

    The OCZ website says the following for my RAM modules:

    Code:
    i965 Chipset
    CAS 5
    TRDC 5
    TRP 5
    TRAS 18
    TWR 6
    TRRC 42
    TRRD 11
    TRTR 11
    TRTP 11
    TWTP 11                   
    
    i680 Chipset
    CACAS 5      
    TTRDC 5      
    TRTRP 5      
    TRAS 18      
    TRTRRD 6     
    TRC 33       
    TWR 6        
    TWTR 11      
    TREF 3.9
    As i don't know very much about what these values are good for, i'd like to know, whether you can 'translate' them to the values the GA-EP43-DS3L supports to configure. For example the 'Advanced Timing Control' section and all the setting within the 'Channel A/B' section.
    Code:
    tRRD...........................................
    tWTR..........................................
    tWR............................................
    tRFC...........................................
    tRTP...........................................
    Command Rate (CMD) ....................:
    
    Static tRead Value.........................
    tRD Phase0 Adjustment...................
    
    etc.
    What does i965/i680 Chipset mean?

    Sorry for my noob knowledge, but i'd like to know more about all these things. All my new pc parts were not so cheap, so i'd like to get them running in the way they supposed to run

    Regards, oseeliger

    <edit>
    Well, after further investigation using google and several forums i found out that plenty of people are having problems with GA-EP43-DS3L and OCZ DDR2 PC2-9200 Reaper HPC Edition running in Dual Channel.

    And noone found an acceptable solution ... this is weird .. :(

    It means those settings do not apply to you at all. Those are chipsets for boards that were made years ago.

    What you should do is set all timings I posted for you to the highest, then work your way down. If you are getting errors with them all at the highest posted then you have voltage issues as those are very loose on the high end and should give you no issues at all

    I have seen no issues, but then again not alot of P43 users are overclockers as that is a very budget based board

    Here is some Ram info if you want to read about SOME of those settings >>>
    http://forums.tweaktown.com/f69/memo...vs-bios-27283/

    If you continue to have issues please post back for me the EXACT settings you are trying that fail and I will advise back

    Hi Lsdmeasap,

    i finally found the correct configuration, BIOS settings and RAM placement. I had the 2 modules put into bank 1 + 3 to run them in dual channel. Now i put them into 2 + 4, which, with the correct BIOS settings, runs stable. I think it's a strange behavior anyway, why is bank 1 + 3 not working?

    Whatever ... i am happy that it's working fine now.

    The BIOS settings i made are the following. The green values in brackets i am running right now until my new CPU cooler arrives, since the settings are causing the CPU to run overclocked. The boxed intel cooler is not really useful for overclocked CPUs... the temperature could be even less when not overclocked.

    Thanks again, great forum and great advises.

    Bank 1+3 may not be working if you have a faulty slot on your board. Can you test each slot one by one with one stick of ram? Please run this test at stock with one stick, do 5 passes for each slot. Be sure you set your ram voltage and put performance enhance on standard >>>
    Memtest86+ - Advanced Memory Diagnostic Tool

    That is if you do want to check your slots, if not then dont worry about that. but do keep in mind if you have a bad slot you would want to RMA now instead of later when you maybe wanted to add more ram and then remember you maybe have bad slots and never tested

    But then again, some boards just work better with certain slots. That does not always mean the others are bad, they just may need different settings is all

    Settings look good! Ya, Stock coolers are only good for stock speeds, any more then that and they got hot pretty quick, especially since Intel took out the Copper core centers on them

    Good luck with your tweaking and testing

    Thanks for the kind words and post back anytime if you need some help when you get your cooler or otherwise!

    Hi all,

    i have bought a new GA-EP43-DS3L motherboard,and i am facing problems in startup and shutdown and hope that i could have your advice.

    the problem is when i shutdown the PC, it won't fully shut down, i can see ledin case is still on, psu fan still spinning, this takes around 5 min then go off.

    then if i tried to power on the PC again, it won't start on the spot, i have to try many times by pushing the power button till its up and running.

    so any clue what might be the problem

    Thanks
