    Hm, I have a somewhat similar issue with my GA-EX58-UD5....

    I have 12GB of G.Skill 2000MHz CL9 RAM, rated for 1.65v.
    As the board will only do 1.64v or 1.66v I have tried both, but it will only see 4GB at 2000 MHz.
    At 1800MHz CL8 it will see it all, but to get this I have to reduce my BCLK to 180.
    At 1600MHz CL7 it will see 8GB.
    At 1600MHz CL8 it will see it all, this is what I am currently running at (200MHz bclk)

    I have the board and mosfets on an EK full cover waterblock on its own loop with a 240mm Swiftech Rad and an MCP655 pump, and the CPU on an Apogee XT powered by a Laing DDC3.25 with an EK top with a Thermochill pa120.4, my point being that cooling capacity isn't an issue if I need to crank voltages up...

    What voltages should I increase to improve this? I'd love to see 2000MHz on the Ram!

    You need to find the right settings is all, that is if you do not have bent CPU Socket pins.

    For 12GB you should use 1.66-1.7V anyway, no need to worry about using 1.65

    You will need to tinker with IOH, QPI/Vtt, QPI PLL and uncore settings. I don't think you will have a very easy time running 12GB at 2000Mhz, the kits are rated to that by themselves. You may be able to do it, but it may take some crazy voltages to do so.

    1800-1900 may be much easier, and of course 1600 would be a breeze.

    Let me have your full current settings, template link is in m signature, and I can advise you further on things. Let me know what your optimal choice of Bclk and ram speed would be, under 2000Mhz for now

    Yeah, until reading this thread I just figured it wasn't happening with 12GB.

    I'm at work right now so I can't tell you the exact settings off the top of my head, but last night I got stable at:

    205bclk, x20 + turbo for 4300MHz
    1640MHz Ram
    8-8-8-20-2 timings
    1.55v vCore
    1.615v QPI/VTT
    1.300v IOH


    I don't seem to be able to push the bclk higher with stability, even if I drop the multi down to x19 and turn off turbo.

    The issue of "bent CPU pins" interests me, it is a brand new mobo but after some of the controversies of Core i5's burning out their socket pins I did have it out and look at the pads, and there are pins that do not make central contact with the pads, and some pads where the mark from the pin seems almost off the pad.... This I guess would be a motherboard fault?

    I know these voltages are high but I need this CPU only to last until core i9, I don't care if it dies then. If it dies before I'll just live with my laptop for a couple of months ;)

    You can use 12GB for sure, just may take a little work. And of course you may not be able to run them at full speed of 2000Mhz either.

    You may have better luck with a lower Bclk, in getting the ram faster I mean. But 12GB at 1650 is good really, but if you want faster I can help you try.

    Almost off the pad, or all the way off? I have not seen similar issues with X58 at all, maybe because they are not there, or there is so many pins it does not matter so much? Anyway, no real way to tell without having a unused CPU and installing it once, then looking. As you will have multiple "Marks" on the pads do to multiple installs. So no real way to say where the pins are actually setting.

    I just looked on a 920 CPU I have, no "off" marks on mine. So maybe the ones you are seeing are coming from just sitting it in there, before it is actually closed and pushed down? I can post pics if you want to see mine to compare, let me know

    Slipkorn_78,
    can you confirm that BIOS F2b,F2 and F3a have issue with i7-965/975.
    According to ZoLKoRn's PM to me,the multiplier limit is at 16x.

    Btw,EX58-UD5 with 12GB of RAM-stable:

    1600 a breeze? please tell me what voltages to use for 1600 with 12gb gskill DDR3 2133 (PC3 17066). UD7, and 950. Bios f3c. I cant get 12gb to show at all. Well not at will. Sometimes it shows but most of the time its 10gb or 8gb. I've tried many different combinations of voltages (IOH, QPI/VTT, QPI/PLL. DRAM up to 1.7) What is the pattern or formula or reasoning for the correct voltages? Any help would be greatly appreciated.

    Hi Nugzo, I see your issues at XS and have just not had time to reply and help you out there yet.

    If you would give me your current full settings I can help you out for sure. About all your 8-10GB issues, please keep these thoughts in mind >>
    Asus X58 + 6/12GB memory overclocking - detecting less memory than installed

    It is often QPI/Vtt and ram voltage relationships that cause this, I can cause it anytime on the fly with 6GB or 12GB

    There isn't really a pattern, just all CPU's differ. Some like the QPI/Vtt to be closer to the ram amount, some less, and some do not care what you use.

    What QPI/Vtt, Vdimm, and IOH have you been trying that fails? And what works for you at 6GB? Are you also trying QPI PLL? This will help me when I advise you back

    well there we have it. i spent all day yesterday trying different combinations of the above settings, nothing posted 12gb. the only time recently it has posted 12gb, was at current 24.7 settings. i just shut it down, added the other 6gb, it posted, failed overclock, but showed 12gb. loosend timings, bumped voltages, restarted, showed 8gb. tried for an hour to get the 12 back and couldnt. at that time i swapped the 6gb that was working with 24/7 settings, passing intel burn test, with the other 6gb that i took out yesterday. has been error free with that 6gb installed. also ran memtest 4.0 with each 6gb and passed hours with no errors. let me know what you suggest and i'll try it immediatly.

    just read the link you posted above. while waiting for your reply, i'll reseat cpu and examine pads. I'm using a TRUE 1366 with stock brackets.

    re-seated cpu and bumped vdimm to 1.74 and qpi to 1.5. 12gb working now at same clocks. i dont know if it was the re-seating or the extra vdimm. i'll drop vdimm/qpi and test. is 1.74 too much? they are cooled with the fans that came with the perfect storm. dimms are warm to the touch.
