Detailed Mainboard Specification List:

Packaging

DFI kept the DK P55-T3eH9’s box art design simple, yet effect, with the board name and supported technologies clearly labeled on a black and grey background on the box front. The following accessories are included with the board: a florescent rounded IDE cable; SATA drive and power cables; the rear panel shield; 2-way NVIDIA SLI and ATI CrossFireX connectors; BIOSecure USB interface cable; Smart connectors; and the normal complement of manuals and drivers discs. The Smart connectors allow for an easy interface for connecting in to the motherboard headers. You simply plug in your front panel jumpers in to the white connector and the USB 2.0 jumpers in to the yellow connector blocks, and then plug both blocks in to the motherboard headers. The BIOSecure interface cable allows you to flash the BIOS to or from a connected remote device or motherboard.

Board Layout

The DK P55-T3eH9’s layout is well thought out, with no real tight areas on the board. DFI seemed to cover the board hot spots with an interconnected heat pipe cooling solution as well. The one flaw was the lack of active cooling integrated in to the heat pipe cooler, but this is easily remedied. While I could find no definitive serial number marking on the board, the board revision is silk-screened to its surface just above the PCI slots, with the board tested being a revision A. For the board’s power needs, DFI chose to use high quality polymer solid-electrolyte capacitors.

The board’s CPU socket area is obstruction free, with all power components directly surrounding the socket of an unobtrusive low profile design. The heat sinks covering the power components are far enough back so as to not interfere with CPU cooler placement. DFI chose to use the standard LGA1156 4-hole based hold-down mechanism for securing the CPU cooler. Just above the CPU socket and hidden behind the cooler are the rear panel USB standby power jumper, the S/PDIF header, and the PWM fan header. The rear panel PS/2 standby power jumper and the 8-pin ATX12V power connector are to the upper right of the socket. The CPU fan header is located to the right of the socket, along the edge of the board.

The onboard DDR3 slots are located underneath the CPU socket, sporting a bi-colored arrangement scheme. Dual Channel memory mode is active with modules placed in like colored slots, with the black colored slots being reserved for the primary memory modules. Below the DIMM slots are the ATA-133 IDE port, the 24-pin ATX power connector, and the fan 4 header. The DRAM power indicator LED is located in the lower right corner of the board.

The board’s P55 chipset is located just under the secondary and tertiary PCI-Express x16 slots, covered by a low profile cooler. This cooler also acts as a termination point for the onboard heat pipe cooler. The 8 onboard SATA II port are located just below the chipset cooler, with the Intel controlled ports being those colored florescent orange. The standby power LED, Chipset fan header and BIOS flash header are located to the left and upper left of the SATA II ports, with the front panel header being in the lower left corner of the board. The onboard power and system reset buttons, as well as the CMOS reset and backup BIOS clear jumpers are located just above it. The 4 onboard USB 2.0 headers, as well as their tied standby power jumpers, are located to the upper left of the chipset cooler.

DFI incorporated 7 total card slots in to the DK P55-T3eH9’s design: 3 PCI-Express x16 slots, 2 PCI-Express x1 slots, and 2 PCI slots. The onboard floppy port and serial port header are located along the outer edge of PCI slot 2, with the 2-digit diagnostic LED display located just above them. The diagnostic display is useful in troubleshooting system boot related issues, using the debug codes that it displays during system initialization. The CMOS battery is located in between the lower portion of the secondary and tertiary PCI-Express x16 slot. A floppy style power port, as well as the infra-red and front panel audio headers, are located just above the secondary PCI-Express x1 slot. The floppy power connector is used to provide additional power to the board and video card slots when 2 or more video cards are in use. The chassis fan and CD_IN headers are located directly above the primary PCI-Express x16 slot.

DFI integrated with following ports in to the DK P55-T3eH9’s rear panel: PS/2 keyboard and mouse ports; a CMOS reset button; 5 USB 2.0 ports; 1 shared e-SATA / USB 2.0 port; 1 mini-USB port for use with the BIOSecure cable; 1 Intel GigE Ethernet port; and 6 analogue and S/PDIF optical and RCA component audio output ports. The integrated mini-USB port is used in conjunction with the included BIOSecure interface cable for flashing the BIOS to or from a connected remote device or board.

EZ Tuner

For windows based bus speed manipulation, DFI included their EZ Tuner application on the installation DVD. The applet itself allows direct manipulation of the base clock speed, labeled CPU clock in the screenshot.

Auto Boost System

DFI chose to include their Auto Boost System BIOS manipulation application on the installation DVD.

The Auto Upgrade screens give you access to the currently saved BIOS profile configurations, with the option to both load and save configurations directly to the BIOS.

While the Win Reloaded screen appears to offer similar functions to that of the Auto Upgrade screens, there is one important difference – the ABS Mixer interface. Using this screen, you can combine multiple BIOS profiles in to a single hybrid file. DFI itself provides several preconfigured BIOS configurations for download, with known and working overclocking settings for your board.

The top 3 memory makers have found ways to push their memory beyond PC4000 speeds (500 DDR). Today, we are looking at kits available at PC4400 and PC4300, which is DDR550 and DDR533 respectively.

When topped out at DDR550, that brings the FSB of an Intel Pentium 4 system up to 1100 MHz! This is a TON of bandwidth available for your OC’d P4 CPU. In fact, probably more than you’ll ever need. But at the very least, you will know that you are going to reach the limits of your CPU long before you reach that of the memory, when paired up with one of the above products.

So why pick up some “PC4400″ when you can try to do what they do, and overclock the memory that is already available to you? Well there are a couple reasons. First of all, when buying from Corsair, Kingston, and OCZ, you will be covered by warranty, in some cases even if you push beyond THEIR specs. If you’ve overclocked memory before, you know how volatile it can be. Why not spend the extra bucks and get something that is guaranteed to be stable for all the time you have it?

Basically the main point is, you are guaranteed that these products will reach their stated levels. If you were to buy standard Hynix ram, you do NOT get that guarantee, and if you happen to fry it, you’re left with nothing.

The Looks

It’s no secret that one of the reasons some of us want this ram is for looks. Fancy heatspreaders (and in some cases, activity LEDs!) set these products ahead of every other memory product. They can really put the finishing touches on your modified rig!

Both OCZ and Kingston use nicer clips than Corsair. On top of that, they look a lot better in my opinion. The deep blue HyperX sticks would look sweet in an all-blue setup. And the OCZ copper heat spreaders are absolutely brilliant, and would match up perfectly with a nice big copper heatsink on the CPU. The Corsair is lacking in the looks department, with cheap looking spring clips, and flat black heat spreaders. Corsair is also available in silver.

OCZ Technology has been one of the front runners in the DDR3 memory market and today I will be taking a look at their 2GB 1600MHz Platinum Series performance memory kit. This kit will be very popular in upcoming months once the Intel X48 Express chipset hit the market as this chipset will support 1600MHz Front Side Bus (FSB) processors and 1600MHz memory clock frequencies from the get go.  The kit that OCZ Technology sent out for review is the 2GB DDR3 PC3-12800 (1600MHz) Platinum Series Kit that is part Enhanced Bandwidth Edition. Since that is hard to remember, the part number is OCZ3P1600EB2GK.

Before we get into the details of this new OCZ memory kit, be sure to read our previous DDR3 memory articles to make sure you know what the changes in DDR3 are and how it performs compared to DDR2.

If you feel you have a firm background on DDR3 modules and what the performance level was on various kits, then let’s take a look at what OCZ has been up to since we looked at their 1333MHz DDR3 kit a couple months ago.

OCZ let us know that each memory kit in this series is 100% hand-tested for quality assurance and compatibility, which means they should work when you plug them in! If they by chance don’t, they are covered from the time you purchase them thanks to the lifetime warranty that comes on all OCZ DDR3 memory modules. From the outside, the modules look familiar since they clad OCZ’s proprietary platinum-mirrored XTC (Xtreme Thermal Convection) heatspreaders for the enhanced heat dissipation.

The 1600MHz dual channel memory kit comes rated with 7-6-6-24 at 1.9V and it was able to run either a command rate of 1T or 2T with no issues at this clock frequency. This is due to the fact that OCZ’s 1600MHz memory kits use highly screened Micron ICs that have been found to offer great timings and high clock frequencies. This memory kit was specially designed and optimized using the ASUS P5K3 series of motherboards with the Intel P35 Express chipset, so if you own this board you are in luck.

The Sunbeam CPU cooler utilizes the proprietary Core-Contact technology, which places the four heat-pipes in direct contact with the CPU for the most efficient heat conduction. The four thick 8mm heat-pipes combined with the top-rated TX-2 thermal paste, and the industry first ultra-silent, ultra long life MFDB (Magnetic Fluid Dynamic Bearing) cooling fan with speed control offers great value and industry leading cooling performance with peace and quiet!
