The DFI X58-T3H6 Rolling Review

In an attempt to provide a more helpful review for end users I’ve decided to create this “rolling review” that will be regularly updated in order to provide a source of information and user experience for the reader. Initially it will be a overview of the motherboard and some overclocking results to help you see what sort of performance we’re talking about and at a later stage we will try and deal with any quirks that may arise, BIOS updates and issues that can be resolved.

Firstly I’d like to thank DFI for providing the motherboard and their continued support with suggestions and Intel UK for supplying the Core i7-965 Extreme Edition cpu for testing, your support as always is invaluable. Neither of these products are cherry picked, the cpu is in fact retail and the motherboard, while technically an engineering sample, should be no different to the retail product.

For your convenience here is a list of contents that will be updated as the review grows:

BIOS Overview - What's new

The main Genie BIOS screen - a mix of the usual CPU, DRAM and Voltage sub menus with the addition of some of the new X58 platform controls:

PPM Function - The award BIOS power management function, you'll need it enable to change the Turbo ratios
Turbo Mode Function - For upping the multiplier on your cpu if it's locked
CPU Non-Turbo Clock Ratio - If it's an unlocked cpu you can set any desired multiplier here for all four cores
BCLK/UCLK/QPI Controller settings - The new FSB where you can adjust the QPI frequency, BCLK speed, memory divider and Uncore multiplier

The DRAM and Uncore multipliers are actually linked, due to the requirement for the Uncore frequency to be approximately greater or equal to twice the DRAM frequency.

CPU Features and Memory timing controls
Note that you have control over the over current protection (OCP) of the PWM circuitry, the thermal design current and power (TDC,TCP respectively) of the cpu and hyperthreading inplimentation. In the DRAM timing section a new addition is the Memory lowgap: This feature is for mapping the memory on say a graphics card to the system memory. You may find you have to up this with SLI or CF setups that will be requesting a large portion of memory from the system. Note that as you map off the memory is no longer is visible to the OS.

Got volts?

CPU VID ~ 1.06255 - 1.60000V
CPU VID Special ~ 100.23% - 114.88%
DRAM Bus Voltage ~ 1.455 - 2.400V
CPU VTTSpecial Add ~ +0.0125 - +0.1875V
CPU VTT Voltage ~ 1.21 - 1.61V
CPU PLL Voltage ~ 1.80 - 2.15V
IOH/ICH 1.1V Voltage ~ 1.11 - 1.73V
IOH Analog Voltage ~ 1.10 - 1.45V
ICH 1.5 Voltage ~ 1.5 - 2.1V
ICH 1.05V Voltage ~ 1.05 - 1.35V
VREF Adjustments ~ 0.00 - +15.0%

Worried about the new restraints for DRAM voltage? No need - the Genie BIOS automatically adjusts the CPU VTT to an optimal voltage if you increase the DRAM voltage out of spec - no danger of frying your CPU with the wrong DRAM voltage

You now also get control over the PWM frequency of the DRAM and VTT circuits. Increasing the switching frequency will provide a more stable voltage with less ripple, at the expense of a hotter running power circuit. Better yet you can now change from a PWM to a linear power circuit for super smooth voltage. However this will cause the power circuit run very hot and is not suitable for high current situations like occupying all six memory slots.

Observations and Remarks

My experience over the past two weeks has been pretty positive so far. The motherboard seems to be quite stable so long as you respect the limitations of the new x58 platform with what speeds you can run certain aspects at, for instance memory dividers and Uncore. While the BLCK speed is lower than what others have been able to achieve on other DFI motherboards and indeed other manufacturers I feel 200BCLK is still not too shabby and for all I know it may be just that my cpu isn't so overclockable - I will endeavor to source another i7 with a known BLCK and see if I can go faster

The integrated peripherals of the JR X58-T3H6 are essentially the exact same as those found on the JR P45-T2RS - the same HD Audio via Realtek ALC885, same gigabyte LAN adaptor and onboard IDE support. Though it might have been nice to upgrade the audio I do see one big advantage here. You can simply swap the motherboards and the OS will happily update the Intel INF files meaning you're ready to go, no fuss.

The voltage options on this board are fantastic and the addition of PWM controls is almost overkill - but I still love it! I decided to see what the real world voltages were in comparison to the BIOS settings and discovered something rather interesting:

Voltage readpoints for this discussion:

Having set the voltage to 1.385volts in the BIOS I get the following idling in XP

And with all four cores/eight threads running Wprime

So we see an overvolt of approximately 25mV on ilde rising to 75mV under load. Strangely playing with the Droop control had no effect on these results - go figure.

VTT Also showed a slight overvolt but this can be excused as the readpoint for it is not totally accurate - there will be losses from this readpoint to the actual cpu in trace resistivity so the actual VTT the cpu "sees" will most likely be accurate to what has been set in the BIOS.

Another quirk is that occasionally, if rarely, the graphics card will drop to x8 PCI-E bandwidth. I've only experienced this twice both times after I managed ot make the system crash and immediately reboot. Speaking to DFI it seems that sometimes the apparent width of the graphics card bandwidth can be incorrectly read if the capture time isn't long enough at the boot and if such an event happens, simply rebooting the motherboard will fix it. It's not a major issue but worthy of mention.

awesome work my friend, finally it showed up.

sweet part to combine with what Andre have done with his...

this board will be ideal for gamers , who grab there computer with them @ LAN ...

keep DFIing it

**TheScavenger** · 01-23-2009, 09:35 AM

Thanks for the review, Johnny! Good work.

**pvhk** · 01-23-2009, 09:44 AM

thxs for this nice review...
ci7 965 @4.2Ghz on air with a TRUE!

**PClark99** · 01-23-2009, 06:17 PM

motherboardpro has them up for pre-order now.

http://www.motherboardpro.com/DFI-LP...rd-p-1272.html

$245 plus shipping.

I just checked NCIXUS website. The board was showing a price around $220 before and now its up to $234 but no pre-order available.

I pre-ordered from motherboardpro, I had a good experience with them in the past.

The price on NCIXUS has been fluctuating for awhile. Does this have to with the american dollar to canadian dollar exchange rate?

I have no clue about exchange rate, probably more due to predicted supply vs demand if I had to guess.

that is not the JR but the DK...

**Johnny Bravo** · 01-25-2009, 08:56 AM

Thanks guys - need to get some more testing/benching done now for performance comparison, also I have a quad core rig based on the P45 JR so a little apple for apples comparison might be good too

Thank you Johnny for all of your hard work, I am keeping an eye on this thread so I can get a good idea how to best set up this board when I get it.

**nullface** · 01-25-2009, 09:22 AM

Nice board, but the vcore flying all over the place makes me wonder if my JR P45 has the same "issue" eventhug it isent that bad.

Overvolts a little yes - but its a very stable voltage

**Pedalmonkey** · 01-25-2009, 04:18 PM

Johnny, is the NB HS removable like the P45 version?? just wondering so i can maybe Water cool it too.

Yeah that's great and all, but this thread is pertaining to the DK. Not the JR. Kthnxbye.

**pvhk** · 01-26-2009, 03:33 AM

sure?

this thread is for jr , read & look at the board....

All in the title:

Nice review, but it seems like DFI "fails" again in the OC departement. First notsogood OC on the JR45 and now this, I guess I'll have to get used to that they aint what they used to be.

What are the other mATX boards with similar features that clock better then the ones from DFI?

**pvhk** · 01-26-2009, 05:23 AM

Probably not well informed concerning the jr p45!

Concerning this new jr x58: it has no rival to date in the matw world...

How is this a fail on the OC dept
