*****Official ASUS MAXIMUS FORMULA thread*****

Thanks

Well I've set the memory to 1066. I've read a few articles that state that the memory should run at this speed at the default timings. So far its been completely stable. The heat spreaders on the chips dont feel particularly hot when touched so fingers crossed :) I suppose if they go boom I will end up with two large keyfobs :)
 
Hi guys, wonder if anyone can help me... i just bought another 2gig of Crucial ballistix ram 8500 tracer edition, to go with my already installed 2gig. The problem is the 3rd ram slot on this mobo doesnt seem to be working, the ram lights up around the bottom with a blue glow as usual but it doesnt display any LED's like all the others and CPU-Z onlly displays 3 gig.

Is this just a case of a faulty ram slot ? Or is there anything you guys can suggest, really dont want to have to RMA my mobo as i have just put it together...

maybe if i upgraded the bios or something it might help???
 
Has anyone any idea if setting FSBT too low could cause damage? I believe terminations can be at a range of values (including ground), so I'm wondering if I'm inhibiting a component's ability to reduce its voltage...but frankly I'm stabbing in the dark.

I forget my exact BIOS settings (because they seem quite different to what you really get in the OS), but PC Probe is reporting FSBT at 1.15V (the lowest it would go in BIOS). This is OCCTPT1.2 stable for 30mins, but that's as far as I've got with testing it. My other readings are:

Vcore 1.19V / 24'C
NB 1.38V / 46'C
SB 1.14V / 43'C
SB2 1.55V
DRAM 2.16V (Ballistix is rated 2.2V)

I aimed for the nominal values, but am unsure what the FSBT nominal voltage is (is it tied to the NB?). Ditto SB2 actually, I've just got that as low as possible as I don't know the nominal voltage.

Just installed this board but think I've missed something, when I turn the power on it just sits there doesn't boot nothing the red,amble and green led's are lit. Now all I've got power wise is the 24 pin connector but I've noticed a EATX 12v 8 pin connector on the top left of the board it has a cap over 4 of the pins do I need to connect my power supply to that has well? (4 or 8 pins) Sorry if its a n00b question but the instructions don't really say my last board didn't use it I know things have moved on a bit my PSU is a Tagan 580W which is a modular unit.

i see this board overvolts so if i want 2.2 going to my memory what shall i put in bios ? also does it overvolt the cpu?

If you set 2.15v in bios you shouls get 2.2 there abouts , with loadline caliration enabled your cpu volts should be pretty good to what you set in bios , with loadline calib disabled you will get droop
 
From what I've seen all P35/X38 boards overvolt & undervolt.. there are little mods here n there (and loadline calibration) which fix it a bit.. but it seems to be a "feature" ;)

So given the lack of response on what FSBT practically does, am I to assume you all take a completely pragmatic approach towards overclocking? :confused:
 
from anandtech

"FSB Termination Voltage: Maximum of 1.50V. Undeniably the Achilles' heel of this fine board, 1.5V (VTT) is simply not enough to carry most 65nm quad-cores above ~500MHz FSB. Most CPUs/MCHs require this voltage to quickly ramp up from the default (1.20V) to near maximum when overclocking from about 450MHz FSB and higher."

and from XS forums:

"FSBT is directly related to hte CPU PLL, so if not upping the FSBT a lil with the PLL and too low a GTL volt ref, it is not gonna' return as stable or high CPU and system FSB for overclock."

So the FSBT is just the VTT voltage, which is basically the voltage the FSB is running on. So from what I understand.. you shouldnt need to increase the FSBT much above 1.2v until you're over 400FSB... and I don't think that it needs increasing much above the default at all until you're over 450 FSB.

hope that helps a bit :)
 
Thanks, that sounds good given I'm running a FSB of 400 with the CPU on stock volts and the FSBT at 1.14V :)
 
Hi all,

Anyone having issues with Vista not picking up RAM when using this board. I have 4GB crucial ballistix installed but vista is telling me i only have 3gb... any ideas...?
