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

Thanks slim , I will let you know when my qx arrives.

Are these known to vdroop ? Mine does badly , 1.35 set in bios shows 1.28 in bios systems monitor and drops to 1.248 in windows under load . I dropped it two notches to 1.3375 and the windows readings are the same , it primed ok but wont restart now .

Mind you thats at 3Ghz because thats all I can get out of it . My MF did 3200 at 1.25v bios 1.21 under load .

Im growing to hate this mobo.

My striker has overvolt lol! gives 1.39v when I put 1.32500 in BIOS w/ LLC enabled, but vdroop is almost not noticeable.

1.31750 gives 1.39 in idle and in load sometimes go down to 1.38v
1.32500 (after 1.31750) gives 1.39 in idle and load too

I've been reading this thread over the past couple of weeks with a vested interest, its certainly opened my eyes to some of the finer points of the 790i boards.
Had the EVGA 790 board and its was awful, had the blackops X48 which was doa and now I have the Striker II Extreme (so far so good on this one)

Been working on a nice steady overclock but not sure if i've hit a wall in terms of FSB speed on a quad-core. The system is rock solid under 3DMark and gaming, it just wont prime.

Ideas welcome, cpu-z screenies attached, and FYI NB Voltage at 1.45 RAM @1.9V

Having a play with GTL_REF's here and its like a game of cat and mouse. I adjust the databus on core3 which seems to crap out all the time and that runs through, then core2 starts crapping out. So i adjust that and core3 starts again..../sigh, becoming a bit of a mission this

A weird thing is that the Anandtech article states GTL_REF Ratio 0 is for Core 0/1 data bus voltages and GTL_REF Ratio1 is for Core 2/3. If this is the case why cant the values be set the same on these 2 options?

Here is a very good question Daark!!!
I´ve found my self making the same question several times...
It makes no sense to me the values beeing diferent...

Got it Prime95'ing quite nicely now. Adjusted my CPU Voltage as it was under volting (that a word!!). 1.375 in bios was showing less than 1.35 so bumped it upto 1.41 to show 1.375.
GTL_REF0 is at -102mV as is GTL_REF3 (i have a feeling this is core 0/1 and 2/3 Data channels)

Now to work on temps as I'm spiking to just a tad over 70 Degrees without my AC on and intense prime test for max heat etc.
