nForce 790i SLI/Ultra chipset mobos - Reviews/OC/Guides

OK the dramas continue - after not running this pc for a week due to lacklustre results I tried it again tonight after upgrading my radiator and no boot with last code seen on the display being C1 , it appears that this mobo has decided it doesnt like my ram , or either of the two has expired.

Im going to try single sticks , but this is not looking good .



Edit: Nup it does it with either stick on its own too .

Hope it went OK.
You might want to also try the second slot instead of the first slot.
Sometimes it is a little more forgiving.

RLM suggested I do an overnight reset of bios and this morning it started up as normal , I loaded my safe profile 3Ghz 1.35v 1600Mhz 1.9v and its all fine stable and happy , so go figure.

So,

What is causing everyone to RMA their boards?

I tried to boot a copy of vista working on my X48 box, and it blue screened on boot. (unfortunately, it reboots immediately)

Next step was to reinstall. After it extracts all the files and reboots the first time, it blue screens on boot. (Same immediate reboot)

I have tried every setting for my Q9450, and my 12800 G.Skill 2x2GB Kit: auto, manual, low FSB, linked, unlinked... etc etc. I tried copying other people's profiles, and still blue screen.

Sometimes I can get it to boot a bit farther, but it will either say that it had encountered an error during install and needs to be reinstalled, or it won't boot all the way into the GUI after that first reboot upon install.

Is this something that I should consider RMA'ing for? Honestly, it seems like a hardware issue, but is this simply my inability to configure my bios?

BTW, I have tried 0402, 0704, and 0801 (which I am running now).

Is there a vdroop mod for these motherboards ? From bios setting to windows loaded voltage I am losing 0.1v , it makes my bios setting very high for what it really needs loaded.

RLM - Im currently priming my qx at 4ghz , is it easier on the mobo to clock with lower fsb and higher multi ? How does this affect vcore needed ? Is vcore at 333x12 going to be the same as 400x10 for example ?
