Testing Report: Gigabyte X48T-DQ6 Rev. 1.1

[BenchZowner]

This is my sample ( Rev 1.1 of course )



Well... I'd say a mix of red & blues

That's weird... two samples die for no reason...
Could be a coincidence... could be bad batch of some components ( e.g. really bad mosfets batch )... who knows...

SOrry for your mobo loss m8

Lol i think us i4memory guys should change our name to iKillMobos.

I blew up a Asus P5B Deluxe/Wifi-AP last night, in my dumbness I swapped a cpu out but left a thumbscrew (didnt see it) sitting under mobo. When I fired it up i smelt lots of burning so quick shut it off. But the southbridge (or something very close to it) totally fried and smelled like burnt peanutbutter. Luckily nothing but the mobo was damaged.

At least I can carve up the heatsinks from it. Is there anything else worth salvaging off a dead mobo?

Capacitors and chokes can be useful for GPU mods. Otherwise that's about it but it's a good start.

[fart_plume]

Alot of parts can be used to repair other boards, caps, chokes, mosfets, plugs. in fact i'm looking for an old p4 socket 478 board (dead is ok) to get the 4 pin plug for the cpu power to repair a board.

Hi guys, i'm losing my mind on this mobo.
I'm trying to make my system run properly, but in no case I can make my ram modules to run at 1600mhz. Already changed both modules. I cannot reach speeds over 1280 and SPD infos show 1333. System crashes before bios screen if upper speeds are set. Please tell me something.

This is my configuration:

i know this will be tedious but you need to write out all your memory settings so others can evaluate your problem.

my first thought is to ask you how much vdimm are you using.

[Valdo]

Thx for reply Ace, in fact i try many different settings, i try starting with auto settings provided by SPD (1333 9-9-9-24) and after i set manually 1600 7-7-7-20 trying voltage range from 1.80(default ram setting) to 2,35.
But never... all settings putting memory over 1280 block the mobo and reset the overclock bios settings

Thanks so much Bench with ur settings everest load cpu unless crashes, when i put q6600 at x9 i got crash and now i raise cpu voltage to 1,5, and seems to be ok. I make some tests and after i tell u the result.

A question, what about pink slots???
Now i'm using the greens

[BenchZowner]

The pink slots overclock better, while the other pair have problems reaching high frequencies and may require more relaxed timings in comparison with the pink ones.
So do yourself a favor and switch over to the pinkies

Drop the PCI Express Overvoltage to normal, there's no benefit at all from raising the PCIe Voltage, and there's more harm to it as you're putting more stress on the boards power circuitry.

[Valdo]

Thx again Bench.
Now... i set to default pci/ex voltage but i put cpu on 1,55v to keep windows alive after 20minutes and over of stress.

First image showing stress test.

Now this is my new bizarre problem.
As show in the first image, speedfan receive a cpu temperature of 75c° (sometimes 80), then i put thermal sensors inside cpu bracket and the thermal monitor show me 49c°.
I heard that q6600 sensor simetimes work wrong... is this my case?
Following the sensors images.
Thx again for the great help.

[X4er0]

What's the main difference between rev. 1.0 and 1.1 because i can buy the 1.0 here in the netherlands (mobo is only thing i need to finish my rig )

And i have 3 disks, 2x Raptors 74GB and 1x 36GB Raptor, if i would like to run Raid0 on the 74GB disks i want to use the ICH9 for it and should i use the ICH9 also for the single 36GB disk or is it better to use je JMicron next to the Raid0 on the ICH9?

Tips are welcome...

[Supershanks]

CPU Voltage Control...............: 1.5500v

I said you might want to up it a notch from the 1.4125v i quoted , wasn't particularly expecting that sort of hike
No wonder it's getting a bit toasty, even on water.:0

wait for rev1.1
that will be true X48 platform

[X4er0]

wait for rev1.1
that will be true X48 platform

Thnx m8, and do you also have an answer to my ich9 and jmicron scenario?

Maybe i'll go for 2x74GB Raptor in Raid0 on the ICH9 and single 36GB Raptor on the JMicron paired with my SATA DVD-RW

[Valdo]

U think 1,55 is too mutch? any idea what i can change coming back to 1,4125 and no getting crash?

Any idea on my thermal sensors problem?

I'm not going into many details...but the major one is... fixed burnt mosfets issue when using high voltages

For the rest...I'll have to check with my contact in GB.

And i have 3 disks, 2x Raptors 74GB and 1x 36GB Raptor, if i would like to run Raid0 on the 74GB disks i want to use the ICH9 for it and should i use the ICH9 also for the single 36GB disk or is it better to use je JMicron next to the Raid0 on the ICH9?

You can use any configuration on the ICH9R.
And of course the one you've mentioned.
ICH9R > JMicron

U think 1,55 is too much? any idea what i can change coming back to 1,4125 and no getting crash?

Any idea on my thermal sensors problem?

Well, the inside of the CPU will always be hotter than the heatspreadder's edge... and the DTS signals are more trustworthy in this case.
You can try using lower Vcore to see if your CPU can work stably with less voltage.
Try 1.425V, and if it's unstable move on to 1.45V, and slowly to 1.475V ( if 1.45V is unstable again ).

[Supershanks]

U think 1,55 is too mutch? any idea what i can change coming back to 1,4125 and no getting crash?

for 9x400 yes I suggested using 1.425v as a start point. If that's not stable go to next voltage up, prime or test again, until it doesn't BSOD or primes ok. If you do it that way i reckon you'll be stable before you get to 1.55v.

Your not comparing like with like with the thermal sensor. For the voltage your using 75C is not unreasonable . I'd use Coretemp to track your cpu core temps. The value of your thermal sensors is going to be widely different as it's quite remote from the temps in your cores. I have an example that might highlight the issue. Using Everesyt I get the Temp of my NB, this is around 51C , now i have a sensor like yours fastened to the top of the NB this is reading 35.5C The 1st values from the internal CPU sensors measure the heat being generated. The 2nd value measure the heat being dissapated. In the case of your CPU Sensor it is fairly remote from the action.

Just get your vcore sorted & your temps will sort themselves out.

ok i try next step on monday, if i remember good i got a crash with 1,5 but i'm NOT<---(edit) sure atm (many different tries today ).
Thx again for all the help

[Supershanks]

if i remember good i got a crash with 1,5

which might mean that your memory is unstable as we talked about in the other rthread.

What is the main difference between Ver 1.0 and 1.1, is it different kind of capacitors or ......??

[Darknezz]

Well I get My GIGABYTE GA X48T today. Can't figur out why i can't run my Corsair TWIN3X2048-1800C7DFIN at 1800mhz. could some one tell me why???

[Darknezz]

? 1 more Q why just i run Prime95 at Default cpu speed with out the test failing ???
