Z68X-UD7-B3 Review-Physical
Our RAM slots are just as before, placed as close as can be to the socket to maintain shorter trace length for lower trace parasitic impedance.
Moving over to our PCI-E layout, we have two full speed 16x slots and two 8X speed PCI-E slots from the NF200 chipset, which was carried over as well. Surprisingly we are also granted 2x PCI legacy slots, which many find useful. We also have a PCI-E 1x slot up top.
Here we have gray colored Marvell SATA6G ports, white colored Intel SATA6G ports, and 4 black Intel SATA3G ports.
Sorry for the tilted picture, but here you can see all the connectors at the bottom of the board. Pretty much everything you need, plus two USB 3.0 connectors which can each support up to 2 USB 3.0 ports.
Here are out very handy power, reset, and CMOS clear buttons.
Here we take the heatsinks off, as always this is where the good part begins!
Moving to the back of the board we have our trusted screws, springs, and washers to hold our heatsink in place.
Trusted 8 layer PCB.
Now we are going to move to my favorite part, the ICs.
Here is a VERY crowded picture for you, but I wanted this review to be more of a picture gallery along with explanation. Each section is outlined in a different color, and every picture below corresponds to those colored outlines. You have a guide on the left. So do try to keep up as we are going to zoom through power delivery on this board.
I should note that if something on this board is being powered by switching mode power supply it uses Low RDS (ON) MOSFETs at the least, and the CPU main Vcore uses Driver MOSFETs (DrMOS). This keeps power delivery clean, and unlike many manufacturers, it can help deliver stable power to every component that needs it.
This is the back of the CPU socket area, you can see all the components on the underside. These are DrMOS & Intersil Phase Doublers, which cut down the switching frequency in half so the end result per individual phase is 1/4 the original 1.05mhz switching frequency. Surprisingly transient response is still up to Intel's standards and these boards own world records, and its for two reasons. #1 these phase doublers are designed to work with this PWM specifically, and since its an interleaved PWM, it theoretically can allow us to multiply the bandwidth across all phases. Interleaving allows for the use of less and less output capacitors since output ripple current can be multiplied across 24 phases thus reducing actual output ripple. It also allows us to turn all phases on at once. #2 a 264khz effective (I measured it) switching frequency at the DrMOS allow for more current output at MUCH higher efficiency, which lowers temperatures and should help stabilize the output current. This board supports MultiLevel LLC which incorporates 10 steps, as well as normal LLC, but that is for GIGABYTE diagnostic purposes to tune LLC. So this board has 33 combos of possible LLC programmed in the iTE GPIO in the picture below. As far as I know those are all the possible combinations, so its up to GIGA to tune their LLC over time, but do realize that LLC can and probably will vary across BIOSes.
BTW GIGABYTE says its a TRUE 24 Phase VRM, they designed it and they even showed a waveform:
You can see all the components and what they do. All of the components have been proven on past boards, and the PWM is probably the most advanced mixed signal analogue PWM. Its much more digitalized than its previous ISL6336G on the GIGABYTE X58 boards. This board can output easily 480A of power, multiply that by voltage and you have max wattage output. Of course its totally overkill.
Here we have our simple single stage CPU PLL output VRM. I really didn't have time to see what this VRM outputs too, but the CPU PLL read point is right in the path of its output, and everything else has its own VRM, so it has to be for one of the MANY voltage inputs the CPU requires.
Our 2 phase RAM VRM.
The NF200 is controlled by a single phase PWM, same as the CPU PLL and the PCH, except the end user cannot control it.
PCH VRM, which can be controlled through BIOS.
Here we have our last VRM(Switch Mode Power Supply) Its for the QPI/VTT and System Agent Voltages.
Here is how the PCI-E system on this board works. As you can see I went from the back of the board, because that was you can see physically what each port supports in terms of 16x/8x pins.
Our SATA6G support.
Our VERY complex USB 3.0 and USB 3.0 Turbo System.
Here are all the other ICs and SMD components that weren't covered!
Now we are going to move on to some of the other goodies I have in, as well as the installation of parts!
We have a really cool Kingston high performance triple channel DDR3 Kit.
I love playing around with RAM:
Three sticks:
or Two:
Heatsink installed.
GPU installed, and you can see even though the RAM has very high heatsinks, it still works well.
System up and running with the Touch BIOS!!!!!
