    Default GA-ep45-DS3R & OCZ PLatinum

    Hello,

    I would like some help for my issue (LSD helped me before). I can't get Memtest+86 2.01 to run without any errors (a few left on Test's 5 & 7)

    Should Memtest always run with no errors?

    If yes, then here are my specs for help:

    GA-EP45-DS3R
    4GB (2x2GB) 1066 OCZ Platinum RAM
    Vista (32 bit)

    Then here are my changes to BIOS (at f10):

    DRAM Timing Selectable [Manual]
    CAS Latency=5
    tRCD=5
    tRP=5
    tRAS=18

    DRAM Voltage=2.10

    (Above is what is printed on RAM)

    MCH Core=1.260v
    tRFC=56
    Command Rate(CMD)=2

    Everything else is Auto.

    I'm not looking to overclock-just better stability.

    Not that bad now, but have had a few random BSOD (bad Pool Header). Trying to determine if BAD Ram (and not sure if it would even be that band since everything runs).

    Thanks.

    p.s. I know I can do the start-up with one stick thing, but my first line of thinking is tweaking BIOS settings

    Have you Performance Enhance (in the bios) set to Standard? Also Memtest should show no errors.

    It sounds like your ram is fine and just needs some tweaking. You may also need to change the Memory Multiplier strap to an Alternative.

    Vorlon,

    Thanks

    Performance Enhance = [Standard]

    What is Mmemory Multiplier Strap?

    Thanks

    Thanks

    I couldn't see what CPU you were using, ie either 1066 or 1333Mhz FSB.

    If you are using a 1066Mhz CPU, your memory multiplier if not set to Auto will be showing one of the 4.00 x multiplier straps. I think they have different suffixes on your board - you'll need to clarify.
    Such as 4.00A, 4.00B, 4.00C & 4.00D
    Some or all will be available.

    So a 1066 CPU with 1066 Mhz memory will use a 4.00 multiplier 266 x 4

    If though you have a newer 1333 Mhz CPU, then your Memory Multiplier will be 3.20 x for 1066 Memory.
    Again you may have different versions of the 3.20x multiplier, ie 3.20A, B and so on.

    I have literally just found out that changing the strap (on my setup) to another version, which causes tighter latencies and therefore better memory throughput actually makes me have zero errors in memtest even with modest overclocking.

    Because the straps affect internal timings it looks too as some combinations work better than others (straps vs multiplier vs FSB). From what i can tell, a nicely timed/synched system results in no memory/memtest errors, but of course there are other specific memory bios settings that have a huge affect too.

    As i don't know much about the P45, it might be worth waiting for someone to give you some specific settings to try.

    Vorlon,

    Thanks. I have a Q9450 @ 2.66Ghz CPU. On the Microcenter website, it looks like it has a 1333 FSB. However, my System Memory Multiplier (SPD)=[Auto] in Bios. The Memory Frequency (blued out/not changable) correctly states 1066.

    LSD,

    Thanks. You gave me quite a few things to look at. So my questions is:

    Do most of the changes need to be in the same range (i.e. all lows, all mediums' etc)

    Advanced Timing Control
    tRRD 3-5
    tWTR 3-6
    tWR 4-6

    Should I start with all 3 and a 4? if that doesn't work - go to all 4's and a 5, etc?

    Thanks

    Set all highest of the ranges I gave first and then slowly work your way down testing with memtest86+ as you go (Must be this newer version) >>>

    LSD,

    Thanks. This is going to be longer than I thought:

    1. Both the new Memtest 86+ 2.10 and CPUID Still read my memory as 5-7-7-20, even though I set manually in BIOS. Also, both think it is DDR3
    Attachment 638

    2. Look at these timing & Driving Settings. I have no idea how B did not go AUTO when A did. I am changing B to Auto, but thought you might like to know.

    A-DIMM1 Clock Skew Control=[Auto]
    A-DIMM2 Clock Skew Control=[Auto]
    B-DIMM1 Clock Skew Control=[-700ps]
    A-DIMM2 Clock Skew Control=[+600ps]

    Diving Strength:
    clk Driving Pull-up Level=+7
    Data Driving Pull-Down Level=[-3]
    Cmd Driving Pull-Down Level=[-2]
    Ctrl Driving Pull-Down Level=[-1]
    Clk Driving Pull-Down Level=[-6]

    Weird huh?

    3. I even set all my other settings to Auto (MCH, DRAM Voltage). Even with 2x2Gb sticks, system boots and runs fine, but I just want Memtest to be clear first . It seems stable otehr wise

    Thanks again.

    Ya, ignore the DDR3 issue. I reported that as well at the forum about the new version.

    Does Memset show 577-20 as well? What are you setting it to be? And you do have performance enhance on standard right?

    Ya, I would set all those to auto for now

    How does 2.01 test out for you?
