geez man you need more juice on nb 1.5v more if needed youn on water so ...
n trfc of @ least 50 even 55
i can run any 4 sticks on my x38 n u runnin x48
n use bios 602

I have bios 602
With 1 stick of memory and ALL default voltages (CPu @ 1.18v) I can run 8x400FSB perfectly stable @3200 MHZ on the CPU.


Keeping the FSb at 400mhz: Slots 1&3 (green) - Dual Channel
With 2 sticks of memory and NB at stock voltage Intel CPU Burn Fails.
With 2 sticks of memory and NB at 1.4v CPU Burn Fails.
With 2 sticks of memory and NB at 1.5v CPu Burn Fails.

Keeping the FSb at 400mhz: Slots 1&2 (green & yellow) - Single Channel
With 2 sticks of memory and NB at stock voltage Intel CPU Burn Passes!

So then, what do I need to do to get slots 1&3 working together so I can put this other 4GB of memory in and run dual channel? Is this a problem with the CPU or the motherboard?

Also I cannot go over 400 FSB, 410-430 FSB fails no mattery what I do so far. Increasing NB voltage does not seem to make a difference, even underclocking the CPU using x6 multiplier does not help. I even added voltage to the VTT and no dice, I can't usualy even get into windows at ANYTHING over 400 FSB. I'm so frustrated right now I'm about to toss this Hunk of crap Intel out the window and go back to my Opterion 165.

even if you got a brand new board its not gonna change
you need need perfect gtl settings to overclock a quad
gonna be another sleepless night for u
i did not sleep the night i got my e8600 till i got it runnin @ 4.6
i even swapped out my x38 n put in my ut p35 just cause i forgot 1 bios setting to ennable max special add% but i was fun

[adya]

praz is there an update on the x48t2r/4870x2 issue?
ive got my cash saved and ready to get me a 4870x2 for this board.
how definate is this fix do u think?
otherwise i guess ill have to change my plan and use a p45 board for my x2.

This is a situation where either the components work together or they don't. So a progress update is a bit tricky. I do know the engineers worked through the weekend on it but as yet there is no news of a fix. There is a thread over at the club one should keep an eye on as any news will mostly be there first. The only DFI boards I know of the 4870X2 working properly with are the P35 and ICFX3200. And there are not enough reports from using these two boards to know if all users will have the same success.

I have seen that a lot of you use bios 602. I jumped directly to the latest bios (se sign). Are there any difference of fsb clock between these bios?
Mine E86 starting to scream after voltage allready know around 4.25GHz and I have seen other with same batch do 4.5GHz at 1.35V. I need atleast 1.41-1.43V to
get it stable at 4.5GHz.

3.8Ghz ---> 1.15V
4.0GHz --->1.21V
4.25GH --->1.31V

What bios do u recommend me to use...?

Ok so how do I adjust these values? So GTL adjustments are the settings that allow dual channel to work? IS the problem I'm having CPU related then? I don't understand why I can run single channel 2 stick of mem fine but dual channel does not work no matter how much voltage I send the CPU. I also don't understand why I can run default voltages up to 3.2 ghz but anything over 400 FSB and I can['t even boot even if I max the safe voltage on all components?

do some reading
gtl setting is the key to stability its cpu related

yea everytime I search GTL all I find is people recommending people tweek these settings, but when looking for how to do so I come up empty handed. So I must be searching xtreme [H] google for the wrong thing....

edit; I foudn this article
http://www.anandtech.com/printarticle.aspx?i=3129

Carefully read it. However they don't tell me what to set the GTL values to when using default/stock VVT voltages.

[DiscoTech]

how is this motherboard for quad cpu + micron ddr2 overclocking on air?

cpu is q9450, ram is 4x1GB micron d9gmh.

I will not be crossfiring so I was thinking about going with either P5Q Deluxe (~$200) or the Biostar Tpower I45 (~$150).

How does the LT x48 (~$250) perform compared to these boards in overclocking?

Which board would you pick?

[SuporterPoli]

My UT X48 wont do over 450FSB without gtl tweaking. My P5Q Deluxe on the other hand does 475FSB without that. Q9450,2x2GB Redline here.
So my vote goes to P5Q Deluxe.

I quess I have to play with my GTL as well on this bios. With last official bios 2008/03/20 I could do 500fsb...

Thanks for the link, bookmarked! I tried the settings suggested for default VVT 1.10v GTL 95/90/75 and I still can't get Intel CPU burn to pass using 2 sticks of memory in dual channel (PC is only stable in single channel). I'm only attempting to get 400 FSB stable here nothing too crazy.

edit: achieved 3.0ghz Intel Cpu Burn Stable!

Now when looking at the PLL charts, it says VVT voltage setting in bios, then actual voltage. Where are they getting the actual voltages? Are they getting the actual voltage from the bios reading, CPU-Z, Multimeter?

Which should I go by when using the charts?

Right now my VVT setting is 1.35v, PLL 120. 110, 90 CPu voltage @ Auto + ~111%, Nb @ 1.5v

Seems crazy to me that it takes so much voltage to get 3.0 GHZ Dual Channel, where stock voltages are perfectly stable in single channel memory configuration. Someone have an explanation for me?

[safan80]

did you guys see this? I have two 4870x2 that I can't use because the 7/25 bios flash killed my bios.. I bought a new bios chip though that should be here tomorrow.

All the charts I find say they are for G0 CPU's I'm assuming I do not have a G0 Q9450 because I don't see that number in the stepping anywhere.
what would I call this one so I can try to lookup a GTL chart for it?

ok, just wanna know what settings you used to take that pic

F3.5, 190th of sec, ISO 100, no Flash, 50mm F2.0 lense Olympus e520.

I'm not googling many charts for the GTL settings for C1 stepping Maybe I will just have to guess but thats exponentialy tons of extra variables.

I'm wondering if it is better to run the PC @ 3.2 GHZ single channel (4GB ram) with default voltages or Dual Channel pumping all that crazy voltage going into the CPU @ 3.0 ghz (4GB ram) Pending testing with 8GB when I get home.

i was just looking at some x48/quad voltage settings that some people have . noticed vtt is really high on some for 400+fsb.
ive always kept mine low , but now im thinking i made need to up this abit.
is it true that higher vcore requires higher vtt?
or is vtt meant to be a % of ur vcore?
thinking for 450fsb /3.8ish i might need to go to 1.45vtt +?
gtls i can take from clunks or evas chart but not sure about vtt.

Great Question I want to know too! Going to play around with lowering some voltages tonight.

Page 13 Quad-Core Overclocking, continued

Approximate VTT values and FSB ranges

VTT = 1.2V - 1.3V = Up to 400 FSB

VTT= 1.4V - 1.55V = 420-440FSB

VTT=1.6V (~1.58 actual) = 440-475FSB

found this ,good read for vtt in that article.

Isnt that based on 55nm tech like the Q6600s? 1.6v seems really high to me.

@Justintoxicated
bro, get a multimeter when you get a chance, pick a VTT voltage, e.g. 1.3v, measure the the voltage under the load. Let's pretend it was 1.29v, now multiply that by .63 (1.29 x .63 = 0.813v), take reading of the CPU 1/3 0/2 NB and adjust the values - or + until you hit 0.813v. All point measuring points on latest DFI LanParty boards are unviersal, http://www.edgeofstability.com/artic...asurement.html. Here's what I did: http://csd.dficlub.org/forum/showthread.php?t=7723.

I have a fluke DMM but what should I use for the grounding point? A ground from a PSU cable?

I got it stable at 3200 MHZ but not going off the chart, but rather off another users advice for these new chips. Acording to his post the 67% rule doe snot work for newer steppings.

Running 8x400 FSB
CPU at 1.34v (according to the bios)
NB 1.510
VTT 1.4
GTL's:
1/2=120
110=110
NB=130

who ever said you need 67%
you need 61-63%

For the ground spot use the the metal around the holes for the mobo screws. You should go with 63% and from there go downhill until you find something that your system likes. I would recommend to leave the GTL disabled for now since those values seem to be way to high ?
