    Hi Lsdmeasap ,

    i have been running memtest overnight and have so far had 100% succsess with no errors.

    here are my settings so far.....

    i have included the values that are written in the bios in (*)


    Robust Graphics Booster___________ [Auto]
    CPU Clock Ratio ____________ [8.5]
    CPU Host Clock Control_ [Enabled]
    CPU Host Frequency (MHz)__________ [400]
    PCI Express Frequency (Mhz)_______ [100]
    C.I.A. 2__________________________ [Disabled]
    System Memory Multiplier (SPD)____ [2.00]
    DRAM Timing Selectable_______ SPD __ [Manual]

    Performance Enhance = [Standard]

    CAS Latency Time________________ 5
    Dram RAS# to CAS# Delay_________ 5
    Dram RAS# Precharge Delay_______5
    Precharge Delay (tRAS)__________ 15


    ACT to ACT Delay (tRRD)_________ (3) i have 3
    Rank Write to READ Delay________ (3) " 10
    Write to Precharge Delay_________ (6) " 4
    Refresh to ACT Delay____________ (42) " 40
    Read to Precharge Delay__________(3) " 4
    Static tRead Value_______________ (9) " 9
    Static tRead Phase Adjust________ (0) " Auto
    System Voltage Control____ [Manual]
    DDR2 OverVoltage Control__ [Normal]
    PCI-E OverVoltage Control_ [+0.1V]
    FSB OverVoltage Control___ [+0.1V]
    (G)MCH OverVoltage Control [+0.1V]
    CPU Voltage Control_______ [1.23125]

    CPU Clock Drive..........................: 800mv
    PCI Express Clock Drive..................: 900mv
    CPU Clock Skew (ps)......................: 150ps
    MCH Clock Skew (ps)......................: 250ps

    where you have suggested CPU Clock Drive 800mv and PCI Express Clock Drive 900mv, in my bios i have only one option for both...

    CPU/PCIEX CLOCK DRIVING CONTROL, which is currently set at 800mv

    also i have a few more options which i havnt touched...

    Command Rate (CMD) -------- (2) i have--- Auto

    CPU GTLREF1 Voltage Ratio---- Auto

    CPU GTLREF2 Voltage Ratio---- Normal

    Looks good, you can likely bring down Static tRead when you get some time for more testing. Maybe to 7 or 8

    That is what I would suggest for those GTLREF voltages with a dual core >>
    CPU GTLREF1 Voltage Ratio [Normal]
    CPU GTLREF2 Voltage Ratio [Normal]

    Auto should be used only if you see instabilities

    went right in and brought down Static tRead to 7 and it did the old 3 x reboot then reset so i changed to 8 and rebooted fine, i have run memtest for an hour with no errors but will leave it running tonight, fingers crossed..........

    Looks good then. I would think maybe that because that is the "Budget" ram from Buffalo is partly why it wont do tRD 7, that and the low voltage allowance

    Or you could try it again with either higher Trfc of 42 or so, or try it again with a little more MCH voltage

    Did you ever try 4-4-4-12 with this ram? It might do it, but would likely need 2.0V, but I'd test it anyway with the voltage you are using just to see.

    You know you can save different BIOS profiles? On the MAIN page of the BIOS hit F11 for save and F12 for Load

    been looking at the mushkin ram as you suggested, some very nice looking timings from some off there sticks, problem is thers so bloody many i dunno which stuff to choose

    as you know my board is capable of up to ddr2 1200 but with my processor (E8500) is it worth getting the higher mhz sticks ??

    what particular sticks would you suggest ??

    specs:
    gigabyte x48-ds5 rev.1 F7 bios
    Core2duo E8500
    Vandetta 2 cpu cooler
    EZCool 1050w psu
    2x gigabyte ati hd4870 crossfire

    Well 800 or 1066 ones depending on what you want to run your FSB at. Yeah they do offer alot of ram. Black is the best, Blue follows that. And redlines are the Best 1000MHz ones. I would pick black over red anytime myself. But that is up to you and your FSB really.

    I use Blue ones myself and they are great, Just cant afford the black ones. I am saving to get 996580 (2x2 Black set)

    Most all there ram will scale nicely with volts. Like say a 4-4-4-12 @800Mhz 2.1V set will do that at less then 2.0 normally. And will scale up to 1000 or so with less tight timings such as 5-5-5-15/18 @1000 with 2.1-2.2V

    Same goes in reverse for the 1066 sets, they will do tighter timings at lower speeds.

    And also if you do like a set but do not like a certain color of heatsink, if they have the set at their online store you can call and custom order for free they will switch the heatsinks for you

    went for these:

    XP2-8500 DDR2 - Mushkin Enhanced

    looking forward to getting them, been reading up on reviews and look like they have a solid reputation for quality....
