[pvhk]

hi all!
here's my settings with this board!

[spinejam]

new build q9550 w/ DFI X48 LT T2R , gtx260 videocard, Ballistix 800mhz, corsair tx650 ps.
on startup, led's on, fans spin, but system will auto shutdown at post code 26.

any ideas???

I had the exact same thing happen with my build recently. I ended up having to unplug my video card (major pain due to water loop), unplugged the psu, and removed the battery. I left it like this for about twenty minutes and replace it all back and it worked like a charm. Hope this helps!

[TalBar]

POST code 26 mean video card initialing problems.

tx for the replies -- will try suggestions.

used some settings from there -> http://www.outofspecs.gr/forum/showt...?t=2252&page=2

i managed to boot at my desired settings but it isn't stable.

also, i don't know how do we set the MCH VREFs and the driving strength. if there is a guide or something it would be appreciated.

hey guys, good to see the forums up and running after the downtime. (Im a mod over at TPU, where the refugees hid out and created a hell of a mess in tent city)


Anyway i just got this mobo and i'm trying to sort out a dilemma.
My setup is currently just like these



Unlike that guy with his case, mine has the PSU up there and its causing me some temp issues. I need to find a northbridge cooler replacement thats going to fit, and allow me to rotate the CPU cooler so that its blowing out the back of the case again.

The two main NB coolers i think MIGHT do the job are the Thermalright HR-05 IFX, and the Xigmatek Porter N881 HDT.

I'm working my way through this thread but theres a hell of a lot of thread to read through, so if anyones found a way to get a TRUE120 to fit rotated the other way, please let me know!

Edit: i found THIS picture, but the angle makes it hard to tell if the top PCI-E slot is still usable.

edit 2: just a few pages back was this post which gives me hope. i will try PMing that user to get a pic of his setup

[zsamz_]

mussels you can install the true any way you want
i had to shve my nb heatsink as it was touchin the true
before you replace the stock nb cooling try a 120mm fan
i have the ifx it beats the stock+120mm fan by 2c
i even put a xigmantek 1283 on nb lol but not much temp difference
if you was to buy 1 i think the porter is a good choice

well i dont have the tools to 'shave' my stock cooler, thats why i needed to check what other coolers would do the job.

[zanzabar]

its a much better idea to get a new case IMO, what do u have now

[zsamz_]

i used a dremmel
even a rock can do the job just rub the edge a few millimeters

[mikeyakame]

I originally did it the other way around.

I gently massaged the interfering heat pipe on the TRUE about 1-2mm in. It makes no difference to the TRUE and it just clears the OE heatsink. Only one heat pipe doesnt clear when it's mounted facing IO panel. All you need is a small shifter or spanner or similar, and gently tap the pipe around the area that hits and you'll massage it clear.




Heres a pic with Thermalright HR-05 SLI/IFX.

i managed to boot at my desired settings but it isn't stable.

also, i don't know how do we set the MCH VREFs and the driving strength. if there is a guide or something it would be appreciated.

Driving strength is set for the ICs. 6/8 usually works by default. To adjust you either increase clk drive/decrease dq drive or decrease clk drive/increase dq drive, but you need to change DLL models too when doing this.

On my DDR2 G.Skill 1100mhz 2x2gb sticks I've found the best combo for me is, in the format CK Drv/DQ Drv/Dll 1/Dll 2

3/8/5/5 or 4/7/6/6.

Drive strength is the amplitude the clock out and data out are driven at within the DDR delay locked loop relevant to clock in, and out for ddr mux.

MCH Vref are set with respect to the difference default.

Vref1=00h, Vref2=00h, Vref3=80h.

The represent voltage reference points at voltage crossing. You adjust them to the same ratio they are set. ie, Vref1=05h, Vref2=05h, Vref3=85h.

Unless you understand what they do stick to this. Also you can benefit from adjusting MCH slew rate offset, and MCH ROn/Rtt.

Ie.

MCH Rtt = 06h, MCH ROn = 03h, MCH Slew rate = 0Ah, MCH Vref1 = 18h, MCH Vref2 = 18h, MCH Vref3 = 98h

I'm pretty certain that Rtt = 1/2 ROn when setting it, since Rtt is usually 2 * ROn impedance. ie Rtt = 120 ohms, Ron = 60 ohms.

[Mussels]

its a much better idea to get a new case IMO, what do u have now

antec P150 (same as the solo) i like the case, no intentions to retire it yet.

mikeyakame: without the fan on the NB sink, is the top PCI-E slot usable?

[mikeyakame]

yeah i dont see why not. I don't have a need for it so I use a 80x25mm fan instead there.

i'm pretty sure it doesn't interfere with the slot, been a while since I had my PC apart though.

[exemay]

Hi, im about to order myself a DFI X48 LT T2R motherboard, and am wondering what size fan fits into the NorthBridge Heatsink (AKA The Heat Minator)??? is it an 80mm fan?

also how hot does it get when overclocking? im fitting in my q6600 and planning to overclock it as far as i can (with a GTZ waterblock) should i invest in a NB waterblock??

many thanks!

yah water is a mush for the x38/48, and i if u get the mcw30 its the lest restrictive and keeps the NB +2-3c of the water

mikeyakame: without the fan on the NB sink, is the top PCI-E slot usable?

if u get an antec 300 it would fix all of your problems and they cost like $60 so thats not much more than the NB cooler and some fans

if you not gonna do crossfire get the ut p35 or p45

[exemay]

if you not gonna do crossfire get the ut p35 or p45

im running a 4870x2 and dont really plan on getting another to crossfire cause of the power they will eat......why get a p35 or p45??? what reasons?

[zanzabar]

im running a 4870x2 and dont really plan on getting another to crossfire cause of the power they will eat......why get a p35 or p45??? what reasons?

the p45 ocs better since the NB and vtt voltage stay closer with the 45nm chips, and they have improvements overall + they are 65nm so they have way less heat and can be air cooled when oced were the x38/48 need liquid for a good oc

[exemay]

hmm, well im looking for about 3.2ghtz from my q6600, im currently on 3.2 on my Abit ip35 pro XE board...which has given up the ghost now

im just putting in a new mobo so ill still be liquidcooling my q6600 and will be adding in a NB waterblock....so would you still suggest me not getting the X48 LT???

[zanzabar]

get whatever is cheaper with the x48 or p45

dont get me wrong the x48 is a good board
but its not as fast as the p35 or p45
just get whats cheaper
only reason i'm goin back to x38 soon is that i bought another 4870 to go crossfire
or my x38 be in a box for another year
i'm still itchin like crazy to buy the ut-p45

i'm a silent PC user, the 300 would be far too loud for my tastes (If i can hear it, its too loud) not exactly common for someone on XS am i

[zanzabar]

why is it to load, it has the same sound dampening and more fans, more fans mean that u can undervolt and get the same flow for less noise and it allows the top to be used for a fan and the bottom for a psu so it will be cleaner.

its the same type of case so im just giving a suggestion since its about the same price
