stability is so damn dependant on that 2.3v vdimm. kind of :banana::banana::banana::banana:s me cause its 4x1gb of double sided crucials. there not easy to get and i dont want to kill them. but, at the same time i want to keep this clock setting.
not sure what i should do.
what if i gave vnb 1.7+ ? would that help lower vdimm? if it kills the board , i dont care i hate x48 now anyway.but i want my ram.

I vote don't kill the ram, maybe just lower your clock to a safe level and deal with it...

If u dont feel comfortable at those volts, why not just lower your clock like others mentioned....

what i did notice was there was a difference in vcore and vnb. during occt test , the volts did seem to vary abit. i suspect that is one reason why.
the other thing is ,u have to look at ur stability testing method . i know 1hour or even 2 hrs stable can crash 2.15 hrs later. or can crash 15 min into testing.
now im using occt just for indication but ill use prime blend at end for better result
maybe like me , ur not really 100% stable at 430fsb.
thats was my experience anyway.

The thing is though, I can increase the voltages on everything, VCore, PLL, VTT, NB, VDIMM and it wont boot at anything higher then 430. I seem to have a wall at 430, and nothing that I do will fix it.

u know , i was using 1.4 and 1.5 vtt and couldnt get past 450fsb then i reduced it to 1.35 vtt and it stablized to 495fsb.
have u tried playing with vtt?

man you guys have weird boards :rofl:
the big problem i think is gtl settings its like @ some voltage settings you need different % rate
with my 65nm i could goto 500fsb on auto but with my 45nm i cant use auto for 500fsb
higher the fsb i need lower gtl setting verry weird

I'm still waiting for DFI to get 2 4870x2s working on this boards.. not to mention usb is unstable sometime with the 8/20 bios.

I have some BIOS from dfi.com.tw :D

Thanks for sharing. :)

"X38AD827.zip" is missing. The file in the archive is named "utf-8__X38ADB28.zip" and that's an old beta BIOS.

i got my Q9550 to 3.6 @ 1.19v that good?

also, how do you flash the UT bios to LT

The UT and Lthe same except for the cooling...you can use the UT BIOS and flash it the same way you would flash the LT board...I prefer to use the Diamondflash method DFI offers. You could also use Winflash to do it in Windows if you want to do it that way. I have had no issues doing it either way.

I have altered the original email address in the above quote. I was curious what kind of moron puts up a persons email address in an open forum.

I'm making some progress on these C1's

I now have 3200MHZ OC ALL default voltages with just GTL changes.
Vtt 1.100
NB default
Mem Default
CPU Auto (running 1.2v)

Id post GTL's but that is no help, instead I'm going to try to find a range or at least some percentages. Then I will go for 3.6ghz slowly. It might be better to just buy a new MB where I can leave the GTL's on auto and then I only have to worry about voltages, aparently the DFI MB does a terrible job of setting GTL's on auto. Maybe it's just this 602 bios that is terrible. Perhaps what works great for people with C0 steppings is not the best bios for C1's.....But now I'm afraid to flash it and lose all progress....

why not you can always flash it back
yes gtl settings are a pain till you find the right ones
just remember higher you go on fsb they change verry weird lol

In what way do they change? I'm going for the % of Vtt. As long as I stick to a good working range of percentages I should be ok right? Or do you mean the percentages of vtt change as well? If that is the case I would be much better off buying a MB that likes C1 stepping CPUs. Or buying an older CPU for the DFI.

i myself have 4 775 boards so pickin the right one not hard
the dfi x38 is a fussy board
the higher fsb i go the lower gtl i need to set
mind you i dumped my x38 and took out my ut p35
if i were you i'd get a p5q series board if you dont find the right mix of gtl

Thanks I will try this later

edit: someone tried the bios and it didn't work

I haven't tried it yet though.

well like i said my Q9550 is running 3.57 @ 1.19v and 1.23 nb.

i havent had time to try for more yet.

This mobo is very nice, but I still prefer P35 :D:

http://img523.imageshack.us/img523/1723/nicerl3.jpg

BIOS 8/20, 1.218v real voltage, VTT = 1.293, NB not sure, 1.405v in BIOS, GTL 83 83 83. I'm running 8GB of the new G.SKILL PowerChip at 556Mhz 5-5-5-18 @ 1.899v confirmed with DMM so far, 4:5 divider and 445FSB, tRD 6. I have lot of tweaking left, have to be finished by tomorrow with the build. Anybody has any tips for "Memory Models" for this kind of memory configuration? Thanks.

im about to buy one of these second hand -Swiftech MCW30 chipset block.
anyone know if it fits the x48t2r ? and does the nb heatsink come off fairly easy for installation?

yah its all good i have one, u only have to cover the center 15-20mm^2

and the push pins from teh stock sink come out easy

Nice chip you got there nfm :up:

thanks , i just got it for $30aud not a bad price i think. now i can run two 4870x2 without that damn heatspreader and fan in the way. lol

I know it only few minutes, I will post BIOS shots tomorrow, it takes huge amount of patience to figure out right DS, DSS, Skew, Delays and other settings :). FYI, this is on 8/20 BIOS.

has anyone successfully flashed 820 with winflash? ive tried everything to flash with winflash . doesnt want to work. tried exe and ziped files. both dont work.
whats the trick?
dont want to use floppy . dont have one nor want one.
