PCMark Vantage=> 14892


DDR3 2000 CL9 9-9-24 1T
Sandra Memory Bandwidth-24962MB/s
EVEREST Memory Read-18665MB/s


MSI 4890 CorssFireX
3DMARK VANTAGE 20068


Currently there is only original cooler, when OC to 4GHz, the CPU temperature is too high.
So you have to disable HT to run at 4GHz. As I get other hi-end cooler, I will do more test again.
200/2000 stable frequency doesnít need too much setup. Voltage is also not high. As the experience, P55 OC ability is close to X58.

Finally, pull up CPU/DDR3 clock
CPU 188 X 22=> 4136MHz
Hyper 4 X PI 1M=> 10.608s
CPUMARK 99=> 642


DDR3 2256 CL9 9-9-24 1T
Sandra Memory Bandwidth-26890MB/s
EVEREST Memory Read-19789MB/s


It can reach above 4.1GHz with original Cooler. The CPU OC range is good.
But the original cooler is not good enough, when itís over 3.8G, the temperature could be over 90 degree.
Due to DDR3 only run at dual channel, DDR3 clock can pull up easier than triple channel i7.


GIGABYTE GA-P55-UD6
Good
1.GIGABYTE hi-end P55 products has high quality package and components.
2.24 phase PWM with DES energy saving technology. It makes PWM efficiency be better.
3.2oz PCB, All Japanese solid capacitors, Debug LED and built in Power/Reset//Clear CMOS buttons
4.P55 supports ATI CrossFireX and Nvidia SLI simultaneously.
5.Rich BIOS items, Wide voltage range and good OC ability in CPU/DDR3
6.Built in 10 SATAII, IO expansion capability is high, 8 USB and 2 USB/eSATA combo ports.

Weakness
1. P55-UD6 price is too high for normal users.
2. As new structure, CPU categories are less. Thereís only i7-860 and i5-750 have higher C/P.


Performance ★★★★★★★★★☆
Components ★★★★★★★★★☆
Specification ★★★★★★★★★★
Outlook ★★★★★★★★☆☆
C/P Value ★★★★★★★☆☆☆

As for first stage of LGA 1156 focus on mid-hi end, LGA 1336 CPU+MB price compare to LGA 1156 CPU+MB are not much.
Only if you use i5-750 without HT, these 2 platforms price gap will be 100~150USD.

Otherwise, current P55 boards in the market are around 5000~9000NTD which is 150~275USD.
By contrast, X58 boards are launched around 10 months and the price is around 6500~10000NTD which is 200~300USD.
In MB price, new P55 boards are positioning on more hi-end and the market will have more lower price P55 boards in the future.
During that time, the price gap between 2 platforms will be bigger.

For CPU, LGA 1156 will have more variety i5/i7 CPU, even entry i3 or dual core i7 CPU to support LGA 1156 will make this platform be more affordable.
GIGABYTE will also have over 10 models as naming UD3/UD4/UD6 P55 MB.

Now LGA 1156 platform starts from mid-high market and there are more PCU and vary boards in the market.
We are looking forward LGA 1156 structure platform moving to mainstream market to make users have more choice in affordable price. :)
