windwithme's LGA 1156 review part5-DFI LANParty DK P55-T3eH9 Overclocking test
LGA 1156 is the latest Intel platform which announced two months ago.
P55 is the first chipset designed for the new platform; and at this moment, there are three LGA 1156 CPUs in retail,
Core i5-750, i7-860 & i7-870. By following Intel’s marketing segmentation, almost every MB manufacturers launched P55 product for mainstream to mid-high market.

DFI LANParty launched P55 later than other brands; finally, we found DFI P55 in market in the end of October.
Recently, we also heard some news about DFI’s P55 in mini-ITX form factor, maybe DFI want to create a different segment for P55?

The product I review today is DK version, the mid-range product in LANParty series.
The full marketing name is “DFI LANParty DK P55-T3eH9”. (DK P55 for short).

You can find blue & black color on package; DFI adopts this pattern since early 2009.

Cooler module for DK P55

windwithme December 24, 2009 07:07 AM

There is an extra fin module in middle for enlarging the surface for better heat dissipation.

Cooler module for MOSFET; DFI indeed improves the cooler quality for DK series.

Tantalum Capacitor for audio
“Solid capacitor” produces “artificial” sound, so DFI adopts Tantalum cap in audio circuit.

The memory bandwidth of P55 is less than X58 because the dual channel architecture.

Boot up screen

BIOS menu
It’s the first time DFI adopts AMI BIOS. You can choose the language you want when log in BIOS menu.

OC main menu

Options for CPU

Voltage setting page
O.C. Shut Down Free: DFI patent technology; no “turn off the power” needed when changing the voltage.
CPU Voltage 1.0000~2.0000V
Power Saving Standard means turn ”Vdroop” off; Advance means you allow voltage droop
Super VID ON means lock down the voltage when enabling EIST/C1E.
CPU VTT Voltage +0.05~+0.697V
DRAM Voltage 1.20~2.60V

CPU/DRAMCOMP: When enabling this option, you can get 1~5MHz higher in bclk.

DDR3 setting in detail

CMOS RELOADED: there are four banks for saving customized profile.

PC status

This is my BIOS setting screen capture.
The potential of OC is depending on CPU quality.
Even you get two or more i5-750 which was produced in the same time, the OC result will be totally different.
So, you have to adjust frequency & voltage carefully to get the best result.

CPU: Intel Core i5-750
MB: DFI LANParty DK-P55 T3eH9
Cooler: Tuniq Tower 120 Extreme

Cooler Tuniq Tower12 Extreme ,Hi-end solution for air cooling.

Cooper made basement; five heat-pipe in both left & right side.

CPU 200 X 20=> 4000Mhz 1.34V
DDR3 2000 CL8 8-8-25 1T 1.53V

Hyper 4 X PI 32M=> 9m 52.359s
CPUMARK 99=> 622

Nuclearus Multi Core => 24715
Fritz Chess Benchmark => 24.71/11858

CrystalMark 2004R3 => 294022

1 CPU=> 5577
x CPU=> 20345

windwithme December 24, 2009 08:04 AM

PCMark Vantage => 15482

DK P55 performs stable in 200/ 2000MHz.
To compare with other P55, there is no difference in voltage setting.
OC performance is better than average.

DDR3 bandwidth
DDR3 2000 CL8 8-8-25 1T,1.53V
Sandra Memory Bandwidth - 24479MB/s
EVEREST Memory Read - 18567MB/s

DDR3 2100 CL8 8-8-25 1T,BIOS 1.63V
Sandra Memory Bandwidth - 26008MB/s
EVEREST Memory Read - 19645MB/s

Memory bandwidth of DK P55 is a little bit higher than others. However, the frequency reaches 2100MHz only.
I hope that DFI can break through the bottleneck and release new BIOS for overclocking.
Software bundling is the weakness part in DFI product.
Finally, DFI adds some useful tools for P55 series such as Auto-boost, bclk OC & BIOSecure.

BIOSecure let you recover BIOS when crashing.
Generally, you have to send the board back when BIOS is crashed; with BIOSecure, you can recover it by yourself immediately.

If your board cannot boot anymore, you can user BIOSecure on the other PC or NB as “BIOS programmer”.
Simply “install” the new BIOS via mini USB port, your board with be fully recovered within 1 minute.

Then, let’s try higher bclk and DRAM frequency
CPU 210.8 X 20 => 4216Mhz
DDR3 218 CL8 8-8-25 1T

Hyper 4 X PI 32M=> 9m 24.406s
CPUMARK 99=> 653

Nuclearus Multi Core => 25975
Fritz Chess Benchmark => 25.89/12425

CrystalMark 2004R3 => 305172

1 CPU=> 5966
x CPU=> 21375

PCMark Vantage => 16052

CPU works stable in bclk 210.8MHz, it could be higher if you enable “CPU/DRAMCOMP”.
When OC to 4.2GHz, it still passes the test. Of course, if shows the OC performance.

windwithme December 24, 2009 08:38 AM

Okay, now let’s try the hi-performance gadget “CORSAIR CMFSSD-64GB2D (RAID 0)”.

To test the SATA data transportation.

Some people concern about the SATA transmission because P55 is a “Single chip” chipset.
After the test, we can found the data transmission is almost the same with LGA 775 platform.

DFI LANParty DK-P55 T3eH9
1.New cooler design. Good looking & good quality!
2.SLI & CrossFireX ready, bundled with SLI/ CrossfireX bridge.
3.All made in Japan capacitors; Tantalum capacitor for Audio; Intel 82578DC GbE LAN
4.Various BIOS options; wide range for voltage setting; outstanding CPU/ DDR3 OC
5.8 SATA II & 1 power eSATA
6.Patented BIOSecure technology.

1. To OC Bclk to 220MHz would be better.
2. To cooperate with more retail store, users can buy DFI product easier.
3. Orange slot & connector should be changed.

Performance ★★★★★★★★☆☆
Quality ★★★★★★★★☆☆
Specification ★★★★★★★★★☆
Appearance ★★★★★★★★☆☆
Price/ Performance ★★★★★★★★☆☆

DFI will launch mini ITX P55 soon, which named “MI P55-T36”.
I think DFI is trying to leverage the advantage from IPC department in order to find a new way out.
The quality and cooler design is outstanding in DK P55,
if DFI can release new BIOS for better OC, the Price/ Performance ratio would be very attractive.

Here comes my DK P55 ABS file for your reference.
If you have similar hardware with me, maybe you can try my setting.
Wish you will get a nice overclocking!

Nice work WWM, seems like a decent board. I like the BIOSecure feature. The max bclk results seem about average for P55, hopefully with a BIOS upgrade this will be increased a bit. I dont really like the look of the new cooler myself, but that is just my personal preference.

Keep it up.

DFI's X48 boards were great. Read lot of places they OCd very well while staying perfectly stable.

I'm not a big fan of DFI in general, but I have to say that their USB BIOS recovery feature is absolutely ingenious. That is something that should be implemented into all overclocking-oriented motherboards. They also did a very good job with the layout. This board looks like a very good offering to me.

That may be so, but in general X48 boards were never particularly impressive overclockers, especially compared to P45 motherboards.

Thread Cleaned.

Excellent review as usual Windwithme. :thumb:

martin_metal_88 December 25, 2009 08:03 AM

Perfect review just in time for Xmas! Always good to see you alive WWM. DFI is in my listing for my next board but I think here we have a winner:) This a 860 + 3 video card could make a great folding farm.
