    You may need +0.3 MCH, and you may also need to use a lower tRD too high might cause issues same as too low

    What amount of voltage do you get from setting 1.9V for your memory, check with Everest in computer/sensors, or in health section of the BIOS, you may not be getting enough. Also what voltage should the default be, you didn't link you memory so not sure.

    You may also need to be using D straps at 400 and above FSB, some memory just will not work easily/stable using a lower than FSB Strap

    You may also need more Vcore, but indicated by your only mentioned BSOD you need FSB. I needed 1.35-1.425+ for 400-450 on my 8400 C0 and E3100 E0, not all CPU's can use low voltages so don't believe any "Stepping Hype" (No offense meant nickel020)

    This is the status at the moment, 400x9 works great, I ran Orthos for over 2h 30min without any issues, HW monitor said that it peaked at 49C but the average seemed to be around 47C.
    The settings are:
    400x9
    3.33D SPD
    DDR3, PCI-E, FSB, MCH +0,15v
    CPU 1,325v

    Using this memory:
    Welcome to Corsair :: XMS3 DHX Product Information

    <table style="padding: 10px; background-repeat: no-repeat; width: 750px;" background="../../_images/backgrounds/resource_tab_bg_light.jpg" cellpadding="2" cellspacing="2"><tbody><tr><td colspan="10">TW3X4G1333C9DHX </td> </tr> <tr> <td> Speed Rating

    9-9-9-24 </td> <td> Package
    240pin DIMM </td> <td> Fan Included
    No</td></tr></tbody></table>Maybe not the best OC memory but thats what I got.

    CPU stepping is C0.

    Two Questions
    1. My memorys speed is at 1333Mhz and if I use 3,33D x 400 I get a total speed of 1333MHz. If I set a higher FSB lets say 420 and 3,33D I get 1398Mhz on the memory, is that bad? Should I lower the SPD instead to e.g 2,66D so that the memory will run at 1117Mhz instead?
    2. Is it safe to put a higher DDR3 voltage than +0,15v?

    Sounds good!!

    Na, 1398 is fine on your memory as long as it is stable. Much higher and you may need to loosen a timing or add voltage, ect. Your memory should be fine with +0.15 or even +0.2, DDR3, like DDR2, is made by JEDEC Standards which state that damage should not occur until after +0.3 over JEDEC standards which is 1.5V in DDR3. Of course that is not what applies to your warranty but you would need to go way over +0.3 for the chips to burn and for them to be able to tell and deny you a warranty if something was wrong. I think this memory will likely do 1500-1600 with 1.6-1.65 or so but I could be wrong since the timings are 999-24 for 1333. Either way you are fine at 1400Mhz and a little more voltage if you wanted.

    So looking good, looks like your CPU just did not like the higher FSB then, that or the high FSB and memory multi you had been trying.

    Sorry about the 1.9V memory inquiry, I thought you were using DDR2. Confused a bit at times in this thread I think due to your first question and keep forgetting what we are talking about I think.

    I would like to set a goal for this overclocking experiment, lets say 4Ghz. So either 420x9,5 or 445x9 (?)

    So next step should be something like this:
    420x9
    3,33D SPD
    +0,2 DDR3
    +0,2 PCI-E (?)
    +0,2 FSB
    +0,3 MCH
    1.35-1,4v CPU

    I'd stick to 9, I often see issues with people using the .5 multi's. Not everyone though, so don't feel like you should not test it out as it may work out fine for you.

    You should be fine with auto or +0.1 PCIE, rest looks acceptable to test with. You may or may not need that +0.2 DDR, so only try if you feel you need as much.

    so @ 450x9 Orthos misscalculated after 45min, what should I change then?
