Reaction score
Intel Core i7 has been launching for awhile and the boards are more and more in the market.
However, there is still only one chipset X58+ICH10R which position in high end market.
Since the beginning, all MB makers launched many high end X58 boards and around 300USD. Till now, you can see more mid-range and entry X58 boards.

GIGABYTE provides many models for X58 product line.
There are EXTREME/UD5/UD4/UD3P which total are 7 models.
The price of EXTREME is around 300UDS, UD5/UD4 are around 240~270 USD and entry UD3 series is around 200~220USD.
As per the high end chipset, the price is about 200~300USD. The middle to low is still P4 series.

EX58-UD3R is GIGABYTE X58 most entry model.
Letfs look UD3R body first. Itfs also use exclusive Ultra Durable 3 technology.

4 X DIMM DDR3Csupports 800/1066/1333/1600/1867/2133/2400C2133/2400 are special spec.
Not same as the other X58 supports 6 DIMM, the UD3R support 1 set 3-channel and 1 DIMM, total is only 4-DIMM.
The max DDR3 capacity is 16GB.

CPU VRM is 4+4 phase and support DES advanced.
The latest VRD11.1 which combine with Intel i7 CPU can support Intel energy saving technology.

Heat-pipe thermal module
Itfs with special courting which avoid oxidation. The black color is also more elegant.

GIGABYTE BIOS is more user-friendly. Basically, you only need to adjust clock and voltage. Uncore Frequency Auto can set to DDR3 X2 clock.
This result is stable at CPU/DRAM 197/1970. If you have same equipments or OC requirement, you can refer to this set up.

As UD3R BIOS VTT voltage only supports to 1.495V, so it limits the stable clock.
Nevertheless, the stable sync at 197/1970 is also the high standard.
As running at DDR3 2064, the EVEREST reaches the extreme high bandwidth.

As CPU OC, you can over 4.2G which with latest Core i7 950 D0.
If you only raise the clock, you can pass Hyper SuperPI 32M in 211Mhz.

GTS250 3D performance is mid-high level. It can support most games for sure.
But in Crysis Benchmark, high quality in 1920X1200 or 4XAA are not good enough.

GIGABYTE EX58-UD3R Conclusion
1.UD3R also use GIGABYTE 2oz PCB and Ultra Durable3 components
2. Full Japanese made solid capacitorsCGood quality heat-pipe thermal module
3.BIOS supports wide range voltage and frequency
4.CPU frequency and DDR3 clock are good OC abilityCSupport both SLI/CFX
5.4+4 phase DES AdvancedCIntel latest VRD11.1

1. LGA 1366 is still high price platform
2.DDR3 6 DIMM is better for expansion.

C/P Value ššššššššš™

The evaluation is comparing with all X58 products.
For the components, if you compare with P45 or X48, you can see X58 boards are better.
If you compare to P35AP45AX48AX58, even entry EX58-UD3R also can be over 8-star level.

C/P Value is also comparing to X58 series.
If compare to Intel full series, X58 is the high end product, then the C/P value will be less than 9-star.
So I am used to use the same level and series products as the evaluation standard. Otherwise, itfs unfair.

EX58-UD3R and EX58-UD3R-SLI difference is SLI support, but the latest F5 BIOS also make EX58-UD3R support Nvidia SLI technology.
Itfs also a value added feature for SLI users.

In current X58 product line, the entry model is around 200USD.
GIGABYTE EX58-UD3R in this segment has very high C/P value.
Except the 4 DIMM design, the components and OC ability are absolutely have 200USD product level.

Intel middle to entry is still occupied by LGA 775, so the users who interested in LGA 1366 might think the price is too high.
In late 2009, Intel will launch mid range LGA 1156 Core i5 series, you will find more clear product position.
I think LGA 1366 position in high end product wonft be changed in 1 year.
If you are interested in Core i7 platform and you are budget limited, you can try 200USD entry X58 board. :)
