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.

Nevertheless, the stable sync at 197/1970 is also the high standard. As running at DDR3 2064, the EVEREST reaches the extreme high bandwidth.

But in Crysis Benchmark, high quality in 1920X1200 or 4XAA are not good enough. GIGABYTE EX58-UD3R Conclusion Good 1.UD3R also use GIGABYTE 2oz PCB and Ultra Durable3 components 2. Full Japanese made solid capacitors,Good quality heat-pipe thermal module 3.BIOS supports wide range voltage and frequency 4.CPU frequency and DDR3 clock are good OC ability,Support both SLI/CFX 5.4+4 phase DES Advanced,Intel latest VRD11.1 Weakness 1. LGA 1366 is still high price platform 2.DDR3 6 DIMM is better for expansion. Performance ★★★★★★★★☆☆ Components ★★★★★★★☆☆☆ Outlook ★★★★★★★★☆☆ C/P Value ★★★★★★★★★☆ 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 P35、P45、X48、X58, 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, it’s unfair. EX58-UD3R and EX58-UD3R-SLI difference is SLI support, but the latest F5 BIOS also make EX58-UD3R support Nvidia SLI technology. It’s 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 won’t 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. :) |
Nice article WWM ! Also nice to see the performance of the 950 for the first time here :) |
