Core i7 (LGA 1366) is the most powerful solution in Intel platform, there is only one choice in chipset ~ X58 + ICH10R.
Each MB brands unveiled many X58 solutions in recent few months.
Price of most X58 MB are around USD $300, the design & materials are luxury.
However, in order to make X58 more affordable, some brands produced X58 solutions that priced under USD $250 recently.
To face the bad financial environment, it’s necessary to low down the hi-end platform price; it’s impossible to sell in USD $350 like X48.

DFI launches new product faster than before since 2009; it unveils several X58 products listed below:
Extreme-Hi ~ UT X58-T3eH8
Middle-Hi ~ DK X58-T3eH6
Performance microATX ~ JR X58-T3H6

Our leading role today “DK X58-T3eH6”
DK X58-T3eH6 looks like UT X58-T3eH8, all have great layout and materials; it sells at USD $250, $50 cheaper than UT X58.

DK X58 thermal module, more ordinary than UT X58, but the quality & performance are quite good.


Tri-channel memory architecture
Core i7 embedded with memory control, the memory performance is better than before.





Boot screen


BIOS page


Performance setting page, includes Frequency & Voltage settings.


Frequency of DRAM & Uncore inter work each other; if you set DRAM at 1600MHz, the Uncore will be 3200MHz.
Usually, the system is stable when DRAM:Uncore=1:2.


CPU Feature


DRAM Timing: the first three options are related with performance.
Of course, if you want higher performance, you need better memory module.


Voltage setting
CPU VID Control 1.0000~2.0000V
Power Saving,For preventing voltage drop.
DRAM Bus Voltage 1.455~2.400V
CPU VTT Special Add +0.0125~0.1875V
CPU VTT Voltage 1.21~1.61V

DFI LANParty DK X58-T3eH6 Conclusion:
Positive
1.As high performance as UT X58; similar design & materials.
2.6-phase full digital PWM; all �gmade in Japan�h solid capacitor; on board Power/ Reset buttons; Debug LED.
3.Many intervals for voltage tuning; ABS technology ready.
4.It�fs very stable when OC DDR3 to extreme hi-frequency. When overclocking, it needs lower voltage in DRAM/ VTT than competitors.
5.Realtek ALC889, the best audio CODEC of Realtek.


Negative
1.Selling for USD $250, it�fs a little bit higher. It would be better if the price can be $230.
2.No eSATA port

X58 is the highest level chipset of Intel platform; There are three price segments of X58 products:
Hi-end: over USD $300
Middle-hi: USD $240~$270
Entry: USD $200~230

According to the overclocking ability & performance, DK X58-T3eH6 is a �gHi-end�h product.
If it can be sold at USD $230, it would be the �gmost wanted�h X58 motherboard.

The performance of DK X58 is very impressive.
To compare with the previous DFI product, DK X58 is cheaper, but it would be good to be cheaper.

In my opinion, DK X58 is the best choice for people who want to overclock and chase performance but with budget limitation.
