Gigabyte H55N-USB3 : Mini-ITX done the Gigabyte way...

We start with the same old "swings and roundabouts" in performance figures that you’ll never notice in real world usage:
Power Consumption
Our power consumption testing utilizes the same batch of components under similar circumstances in a bid to monitor variances between idle and CPU load conditions. We install the vendor supplied power saving utilities on each board and enable power saving modes that don't involve any kind of underclocking or CPU core frequency modulation in order to run an apples to apples comparison.
ATX PSU switching losses are absent from our figures because we monitor power consumption directly at the DC rails of the PSU. These figures measure only the CPU, motherboard and memory DC power draw and exclude any other peripherals, such as cooling fans and hard drives etc. Actual AC power consumption for the motherboard will be anywhere from 15~40% higher than these figures depending upon the efficiency of your power supply.
The H55N-USB3's idle power consumption is excellent, although you lose out on efficiency under load compared to boards from Intel and ECS.
Overclocking
Using the stock Intel cooler with our 661 sample, we managed achieve around 4.2GHz Linpack stable:
The Clarkdale IMC isn’t ideally suited to high memory bandwidth, so we settled for a perfectly respectable DDR3-1640 with CAS 6-7-6-18 timings using our high-end Corsair Dominator kit whilst keeping QPI and CPU frequency in sync. This overclock was held stable by using 1.31Vcore (load voltage is likely a lot less as we kept Vdroop enabled), a set VTT of 1.31V and VDIMM of 1.65V.
Pushing higher than this would be possible with improved processor cooling, but as a side-effect requires more VTT if QPI and memory frequency is not relaxed - and we’re already setting 1.31V which seems to be the upper limit of what the VTT VRM can handle. Setting a higher voltage results in the board shutting down during Linpack, which confirms OCP does work on this particular rail.
We also checked out possibilities with a Lynnfield, using our 875-K sample to see what the board can handle:
3.66GHz is the upper level of what is achievable during Linpack with a HT enabled i7 processor. It’s not the greatest overclock, but is better than what some of the other H55 mini-TX boards can manage and is competitive with DFI’s MI-T36, aside from it being easier to cool the processor on the latter due to a better layout. Out of interest, we did attempt multiplier only overclocking too, but found that same overall CPU clock speed limit – any higher and the board shuts down during Linpack.
Should you opt for an i5-750 Lynnfield, CPU speeds up to 3.8GHz should be sustainable, provided you can find a way to keep the CPU cool enough under heavy loads.

Great little board... hope Gigabyte does a GA-H55N-UD4 with the following additions:- Mini PCI-E 1x slot for a WiFi module (like Intel 6000 series of WiFi Link) with two pigtails for two SMA connectors on the ATX IO.
- Audio Codec with Dolby (and BD capable), like ALC889.
Who knows, maybe a GA-H57N-UD4, with the above plus a H57 chipset for some RAID love.

This looks to be just the motherboard I want! I have the Intel DH57JG and it serves it's purpose but the BIOS is quite limited. I've been wanting to have a gaming/HTPC rig that could bitstream for a while now and the only solution was to add an ATI 5xxx series card into the mix. I've tried a few and being a Nvidia fan I just didn't like it.I also don't like the Intel IGP, but having it on the CPU with bitstream capabilities is a huge plus. Someone on the AVS forums has gotten a Nvidia 9600GT to work in the PCI-e slot of the Gigabyte H55M-USB3, the mATX version of this board. I'm hoping to get a single-slot Nvidia 240GT working with this board so I can game a bit on my HTPC and use the Intel IGP to bitstream.

Great review on a very interesting little board.
Does the eSATA port on this board support Port Multiplier?
I don't think it does, but I'm not sure. I don't understand why a manufacturer would bother
to put an eSATA port on a board, and then not support port multiplier. Sheesh--if we need
an eSATA port, aren't we likely to want to plug in more than one thing?
Also, I very much appreciate the way you display the allowable ranges of the major
overclocking/underclocking variables in a table. Some websites don't know how to do this
right like you did here. Thanks for a great job.

This board will be at my door on thursday. I'll be reviewing it with a few coolers and a core i3 530 / core i7 860. I'm going to try to use the h50 as well despite the IC. I'll just make sure there is a cushion between it and the mount. Thermal tape or something.forumator - Tuesday, June 15, 2010 - link
I got my board today but my H50 hasn't come yet, so I'll be interested to see how you make it fit :)Rajinder Gill - Wednesday, June 16, 2010 - link
The universal plate of the H50 will sit on the transistor and also on a few very small and fragile SMT caps. Make sure you do not generate enough down-force to break anything in that area. Long term, rather than using thermal tape, I'd probably cut/file the mount away to clear these components.Later

That's a sensible idea. When I get the board in my hands tomorrow I'll figure it out. I Have extensive experience with the ITX form factor and the Corsair h50. I'll make it work :)NStriker - Wednesday, June 16, 2010 - link
Call me picky, but using jpegs where it should be png or gif just irks me, and this is a prime example. http://images.anandtech.com/doci/3769/test.jpgThat would be 40K at most as a png and be completely lossless if done from the original image.

Can anyone post an image showing where the H50's plate will need to be cut? I just returned my Zotac H55 so I could get this Gigabyte, but the cooler I have already is the H50.IsLNdbOi - Wednesday, June 16, 2010 - link
Instead of cutting the H50 brackets, can we use some thick washers (that are thicker than the components that get in the mounting plate's way)?
