    long time since I've been on a nvidia board... what volts are what?

    SPP = ?
    MCP = ?

    thanks

    Anyone tried with two 9800GX2s yet (although there are no drivers available lol) ?
    I am running on Corsairs + Teamgroup 1800MHz 4GB and everything is great ...

    Here is with GX2 ...

    ive heard the asus board still has fsb holes with the latest bios? :/
    how bad is it? are there many fsb holes?

    Expected to be honest.
    The Striker was a mediocre board, sometimes it would treat you nice and work fine, sometimes it'd be a pita and kill you slowly.
    At least I hope ( for Asus's sake ) that the Striker II Extreme is less buggy.
    Don't know yet... I'm out to buy a nF790i mobo...but this time I'm not going to be a guinea pig or take the plunge without seeing stuff first.
    I'll wait patiently for the rest to take their chances on various nF790i boards first... and then I'm going to chime in...

    patience is a virtue they say

    I have maped FSB holes on nF680/780 Asus Striker, Striker II Formula but on this nf790 there are not usual holes like before (400mhz for example) , i can set any FSB without problem ..... my OC is 550MHz without holes, but i am testing only 45nm cpus ... 65nm Kensfield cannot to be overclocked, in BIOS is some problem ...

    just found this

    "The NVIDIA nForce 790i SLI chipset is comprised of two parts. First is the System Platform Processor (SPP), analogous to Intel's Memory Controller Hub (MCH) or "Northbridge", and second is the Media and Communications Processor (MCP) that provides nearly the same functionality as Intel's I/O Controller Hub (ICH) or "Southbridge."

    so SPP = NB
    and MCP = SB

    why is EVGA giving me such low NB voltage options?

    Because you don't need more prolly...

    With 680i it was different, though eVGA 780i was also only up to 1.55 I believe (don't shoot me if I am wrong). I needed there only 1.45 NB voltage for 450FSB with 1200mhz on the ram with a Qx... 790i seems to need even less voltage according the reviews... though I'm holding out on this one till the dust has settled...

    Finally someone did at least one test on RAID performance. I'm guessing that was for RAID 0. They really should have done a CPU utilization test for the RAID controller, makes a big difference knowing how much CPU is being used.

    From another review I saw, CPU utilization for non-RAID was on par with Intel's and much better then the 780i. I imagine since RAID 0 is so simplistic we can expect similar improvements.

    Thanks OBR.

    BTW, do you have any experience with an NVidia reference 790i board and how it compares to the ASUS?

    it is my own review, i can translate for you anything you want ...

    PS. I have now eVGA reference mobo and it is ocing king, like FUGGER said 600MHz+ no problem ... but against Asus ... has eVGA mobo only cheap capacitors and design is horrible ...

    i have an unconfirmed pencil droop mod image on another machine

    vince is using it but he has a VR on it
    i could not get the pencil mod to work properly so have to try again

    New Nvidia Control panel (6.10) dont work correctly with this Asus board ... it is fully working only on referrence boards (XFX, eVGA ...)

    That part of article is about a FSB strap changing, on first pictures are best MEM performances ... FSB is 400MHz and mem/fsb ratio is 2:1 = mem performance is BEST ...

    On next picture is second rule broken, FSB is 400, but ratio mem/fsb is higher the 2:1 = mems performance is very bad!

    last picture is broken first rule, FSB is higher then 400 (and strap in NB was changed to compatible mode), but mem /fsb ratio is 2:1 ... but mems performance is also very bad ...

    result: if you want the highest mem performance, you have to find best combination of strab in NB and ratio fsb/mem ... but best performance will be with fsb around 400MHz fsb ...

    Asus board is great with NO undervolting, Loadline cal. works perfectly!

    E8400 at 4GHz will be every time better then Quad at 3.2GHz ... Quad is good for 3D06 scores, and video encoding ... but for gaming is better high clocked Dual core ...

    is a stable 8x450 possible with q9450 on air with the asus 790i ultra w/o cutting memory performance?

    many thanks for declaration. is linked or unlinked mode better for RAM and performance?

    i think i will keep the asus.

    correct me if im wrong, but thats not vdroop.
    vdroop is the delta of idle vcore and load vcore.
    in this case the vcore is way low in both cases meansing the board undervolts quite badly around 0.5v

    vdroop is 0.7v in this case, which is higher than the intel spec i think...
    so its both, bad vdroop and bad undervolting :/

    and why would you want 2 extra cores?
    its only usefull in benchmarks and videoencoding, and... heating your room and burning extra watts increasing your electricity bill
