[Best Bang for the Bucks]GIGABYTE P67A-UD3R + Intel Core i7-2600K - 5GHz++ inside

[Benny Lodewijk]

After testing GIGABYTE flagship P67 chipset based motherboard here, this time i'm testing the entry level model, GA-P67A-UD3R.



Main features from P67A-UD3R are :

• 8 Phase Analog PWM with driver MOSFET
• 4 DIMMs DDR3 up to 32 GB
• 2* PCI-E slot x16 (x16, x4) only support CrossfireX mode
• 2* SATA 6Gb/s + 4 SATA 3Gb/s supporting RAID 0,1,5,10
• 4* USB 3.0 + 14* USB 2.0
• 8 channel HD Audio and 1* GbE LAN

Testing Platform
Processor Intel Core i7-2600K Retail L041B204
Motherboard GIGABYTE GA-P67A-UD3R F7A and F7B BIOS
Galaxy GeForce GTX 470 1280 MB
Memory GSkill F3-17600CL7D-4GBPIS running @ DDR3-2133
Kingston SSD Now! V Series 64 GB
PSU Antec TPQ 1200W
Noctua NH-D14 + 2x Fan 3000 rpm
Windows 7 Ultimate 64 Bit

Something i must explain before you guys see all the screenshot, CPU-Z can't detect the actual vcore properly (i'm using CPU-Z 1.56.2 and 1.56.1), the only way to see actual vcore is measure directly using DMM or using Easy Tune6.

You can see the screenshot below, notice that i set LLC = ENABLE.

Vcore idle = 1.512



Vcore full load = 1.488






OK, let's see how it will perform in air cooling overclocking


5.0 GHz Result













5.2 GHz Result













5.3 GHz Result

















5.4 GHz Result














5.5 GHz Result

My conclusion using this P67A-UD3R

• Performing well in OC with cheaper price compare to UD7 and UD4
• Vdroop quite big, hopefully it can be fixed soon
• Easy to run DDR-2133 with high CPU clock
• BIOS corrupted issue using F7A BIOS when OC, has been fixed by F7B BIOS.
• No pin burn or broken after pushing the CPU to the limit :p
