Message: [QUOTE="windwithme, post: 14202144, member: 87435"] BIOSTAR changes to the design style of the new version in UEFI interface Some data of the current hardware are shown on the left, the background is also changed to red which has the sense of speed, and the resolution is 1024X768 It offers English and simplified Chinese for switching [IMG]http://www.twcarpc.com/photo/wwm/2013/BZ87/BZ87B01.jpg[/IMG] Main page of overclocking and effect adjusting [IMG]http://www.twcarpc.com/photo/wwm/2013/BZ87/BZ87B02.jpg[/IMG] Main page of CPU effect adjusting External frequency of 4770K is fixed at 45, i.e. 4500MHz It closes CPU C status energy-saving technology, the lower part is the clock rate and options of built-in GPU [IMG]http://www.twcarpc.com/photo/wwm/2013/BZ87/BZ87B03.jpg[/IMG] DDR3 uses CORSAIR Dominator Platinum 2800C11 It is able to reach stable high efficiency of DDR3 2800 easily after opening XMP technology [IMG]http://www.twcarpc.com/photo/wwm/2013/BZ87/BZ87B04.jpg[/IMG] Voltage page CPU voltage adopts options of increasing or decreasing, the CPU Voltage Offset(mV) is set as 120 overclocking of 4.5GHz Then, CPU voltage will turn to 1.284V shown on the left [IMG]http://www.twcarpc.com/photo/wwm/2013/BZ87/BZ87B05.jpg[/IMG] Without CPU of K version, it can also use external frequency for overlocking in the framework of Haswell, which is an advantage of the new platform The above sets CPU and DDR3 respectively to 4500 / 2800MHz through the overclocking method for conducting doubling frequency and increasing voltage to 4770K Because overclocking frequency of Haswell does not reach the stable level as the Ivy Bridge of the last generation which can reach 4.8GHz in the same air-cooled environment While the following test will compare the performance of the two different frameworks once again, for the frequency is possibly not equal to efficiency after all Testing platform CPU: Intel Core i7-4770K MB: BIOSTAR Hi-Fi Z87X 3D DRAM: CORSAIR Dominator Platinum CMD16GX3M4A2800C11 VGA: Intel HD Graphics 4000 HDD: Samsung 830 Series 128GB SSD POWER: XIGMATEK Tauro 400W Bronze Cooler: Thermalright Archon SB-E X2 OS: Windows8 64bit [IMG]http://www.twcarpc.com/photo/wwm/2013/BZ87/BZ8711.jpg[/IMG] Intel Core i7-4770K overclocking performance CPU 100 X 45 => 4500MHz 1.284V DDR3 2800 CL11 14-14-35 2T 1.668V Hyper PI 32M X8 => 10m 30.456s CPUMARK 99 => 781 [IMG]http://www.twcarpc.com/photo/wwm/2013/BZ87/BZ87OPI.png[/IMG] It compares performance of CPU through 3770K OC 4.8GHz and 4770K OC 4.5GHz 4770K is 3.6% higher in CPUMARK 99 Nuclearus Multi Core => 33835 Fritz Chess Benchmark => 36.37/17456 [IMG]http://www.twcarpc.com/photo/wwm/2013/BZ87/BZ87ONM.png[/IMG] 3770K is 2.7% higher in Fritz Chess Benchmark CrystalMark 2004R3 => 412719 [IMG]http://www.twcarpc.com/photo/wwm/2013/BZ87/BZ87OCM.png[/IMG] CINEBENCH R11.5 CPU => 9.86 pts CPU(Single Core) => 1.96 pts [IMG]http://www.twcarpc.com/photo/wwm/2013/BZ87/BZ87OCB.png[/IMG] 4770K is 2.9% higher in multiplexing CPU performance 3770K is 4% higher in CPU (Single Core) [/QUOTE]
