Power, Heat, Efficiency And Overclocking
Power, Heat And Efficiency
EVGA’s X99 Micro fits mid-pack in energy consumption, which means that it should also appear mid-pack in efficiency. That quick-and-dirty analysis comes from its average-looking performance in the majority of benchmarks.
The X99 Micro did suffer slightly higher CPU temperatures, but differences this small can be caused by paste placement as much as by voltage differences. Power consumption was consistent with the other products, after all.
I guessed at the top of the page that the EVGA X99 Micro’s mid-pack performance and power consumption would place it dead center in efficiency. The actual results are close, but the X99 Extreme4’s extra-low power consumption bent the curve.

Every X99 motherboard we’ve tested is able to push this Core i7-5960X to a 44 x 101MHz core clock, where the additional voltage needed to achieve even higher core frequencies eventually causes thermal throttling. There’s nothing lost or gained in the X99 Micro in this respect.
The X99 Micro ties for last place in BCLK overclocking, though it will allow that same 2% increase to be applied to the 1.25x CPU strap for a 128MHz setting. That will be important when we begin to search for the ultimate in memory bandwidth.
To get that high memory bandwidth, we first need to find a high data rate. EVGA’s X99 Micro helps us by outputting near-perfect DIMM voltage, where both the CPU and DRAM need near-perfection to reach the RAM's rated DDR4-3000.
Memory settings that we don’t often notice, such as slower tertiary memory timings, often allow better overclocks at the cost of bandwidth. EVGA takes the top DRAM data rate, while ASRock and MSI compete for bandwidth superiority.

Sorry .. for i don`t know what reason i saw a 485$ price tag initially ...that was an insane price.
Also, Amazon is selling this board for $250 USD. (http://www.amazon.com/EVGA-Socket-2666Mhz-Motherboard-131-HE-E995-KR/dp/B00MY3SKEY) Lucky us.
List pricing is, on most occasions, marked up. As demand come into factor the prices drop gradually. Most often the consumers reaction causes manufacturers to convey a price drop in the hopes of retaining their client base/loyalty.
Nevertheless, prices are within sanity now :)
Only real complaints I have with the board are 1) the IO backplate it came with was a plain silver and just looked cheap (painted it matte black to match the build) and 2) 2 of the fan headers are only settable via the bios and do not change (have used speedfan and bios for the PWM headers) so had to do some quick mods to make the rad fans run off two headers but not a huge deal,
The IO shield is a cool little option unfortunately since I was doing liquid in a tight case (Corsair 350D) had to remove it to make the tubes reach the top rad, haven't OC it fully yet (just got 4GHz on the chip for now) but looking forward to opening it up :)
