im possibly thinking of ditching my evga 780i for this board. This thread is so long could someone just tell me very quickly the differences in the LT and UT other than price? All it looks like to me is different stock heatpipes.
@hoodlikegaza
yup you got that right. its with the cooling solution.
price n pwm xtra cooling+ :rofl::rofl:heatpipesQuote:

Also if over volting is not a feature then could someone explain to me why it is happening. Eg set 1.2375v in Bios, shows up as 1.248v Load CPUz. Vdroop enabled.
Yes this board does overvolt alot. Make sure you have cpu special add turned onto .23%, auto overvolts your cpu volts more
it dosnt overvolt it dose what u tell it to, and if u have load line or auto settings then u are telling it to overvolt, or u have one of the broken beta biosesQuote:

If I need more I go up, then check SG and Everest to see what it really is.

special add will not be preciseQuote:

hey maybe i get lucky n i goto 600fsb on the next 1:ROTF:
but on every settin it undervolted by 0.01v
oops i messed up on nb volt it undervolted by 0.05 with x48 bios it undervolted nb by 0.02v
btw everest is not 100% accurate chek with dmm n see
Well, I will give it a try with Special Add NOT set to AUTO and see if this might rectify the Over Voltage. One more question for you guys about CLUNK'S GTL Ref Tables, and by the way Clunk thanks for all the effort in setting up this guide Post. I still DO NOT understand if there is a relationship between the CPU VTT and the NB VTT or if there is any.
For example if I use the values of 110 (GTL 1/2 Ref) 105 (GTL 0/3 Ref) and 85 (NB GTL Ref) from Clunks Table for 1.2500v CPU VTT BIOS Setting, what should the Voltage be for the NB VCore in the BIOS, can that be anything I set it to for example 1.405v.
The reason I ask is that P95 failed after 9.5h it fell over executing the 4096K FFT, so I figured I would focus on the NorthBridge
I can understand a little variance but we're talking the difference between 100.24% and 102.6%. Like I said, i'm not pissed about it. It's just that i've never been able to fully trust the Vcore settings. The rest of them seem to be pretty spot on though.Quote:

Well They have blocked the Special Add Option and I cannot use it unless I set the VCORE to >1.3000v. This really SUCKS, so I guess I cannot fine tune the voltage I need unless I run at a speed that requires more than 1.3000v.Quote:

for a short time i had it on x48bios the x48 bios gave me better voltagesQuote:

this mosfet sec gets REALLY HOT! I can barely keep my fingers on it for more then a couple of seconds
anybody come up with a cooling solution for it? or do I just have to make a custom sink?
This is what i did

thanks i will get a sink for thatQuote:

Yes but i also found that a old evga 680i nb fan did the same job .

The bit of cardboard is there to catch any zalman vga coolers that decide to fall off lol...
A couple of quick pics of the UT x48.

Took me a while to get around to OC my chip w/ this board due to work but I finally got my basic OC finished. OC is stable 5 hours Prime Blend and 7 hours small FFT's. Further memory testing done using memtest w/ 3 instances running simultaneously for ~1.5 hours @ a time. Here are my settings:
I'm using some new RAM w/ this set up. I swore I wouldn't buy anymore RAM but I couldn't help myself. After hearing Tony speak of the FlexII's I checked out some reviews of these sticks and was generally impressed w/ their performance and I also like the support forum over at OCZ:up:. So....2 days later....the FlexII's are definitely worth the money.Code:CPU Feature

Other thoughts. Using the 2x2GB sticks must be less stressful on the NB than populating all 4 DIMM slots because 1.29V on the NB is far less than the 1.55-1.58V my Maximus required to run 4x1GB sticks of PC-9200 Mushkin @ 1067MHz 5-5-4-12-30.
I've got to hand it to the DFI guys, they definitely put together a well thoughtout and stable BIOS. I only had to clear the CMOS once and that's when I started messing around with fine delay settings. Other than that it was clear sailing the whole way to 3.8GHz.
I'm using one of those Antec Spot Coolers bent over and blowing on the PWM, I've got it plugged into the system fan plug so that I can control the speed of it via software, but it also has a 3-speed switch on it.

pic of mosfet with sink from accelero s1 i had to cut it was too long it was made for ati card stuk it with thermal tape + a screw
i had to lap my pwm sink too was bad i added those pics too
man :up: that is power and beauty :p:
