Testing:

Testing this latest Z77-based board from ASUS will involve running the P8Z77-V DELUXE through OCC's test suite of benchmarks, which includes both synthetic benchmarks and real-world applications, to see how each of these products perform. The gaming tests will also consist of both synthetic benchmarks and actual gameplay, in which we can see if similarly prepared setups offer any performance advantages. The system will receive a fully updated, fresh install of Windows 7 Professional 64-bit edition, in addition to the latest drivers for each board and the AMD 12.8 Catalyst drivers for the XFX HD 7970. To ensure as few variables as possible, all hardware will be tested at their stock speeds, timings, voltages, and latencies – unless otherwise stated. Turbo Boost is disabled to make a fair comparison without skewing results.

 

Testing Setup:

 

Comparison Boards:

  • Gigabyte Z77X-UD5H

 

Overclocking:

When you make a comparison of how well a board overclocks you can look at variances in the quality of the silicon and what each CPU will bring to the table. Each board will deliver an overclock that is slightly different from board to board and CPU to CPU. Some do better with bumping the multiplier only up as high as it will go while others benefit more from tweaking the bclock as well as the mulitplier. Different strokes for different folks as it were. The CPU used in this test has a maximum stable clock speed of right at 4.7GHz, this being known up front means I needed to work between the multiplier and bclock to wring the most performance out of this combination. Overclocking on the P8Z77-V Deluxe can be accomplished in several ways. You have preset options in the BIOS, manual tweaking of the BIOS, and using ASUS AI Suite II TurboV Evo utility. Each has its pros and cons. Manually tweaking the BIOS will yield the highest overclocks but takes the most time to reach the highest clock speeds. In the past TurboV Evo had been a little conservative when it came to overclocking the CPU as it took a good, safe clock speed and made it work. At this point in its development it has become more aggressive as the hardware is now more capable with most socket 1155 Core Series K SKU chips able to get to 4.5GHz without a lot of tuning. Using this tool I was able to get a fully stable 1.0+GHz overclock right up to 4.51GHz (105MHz x 43) or 600MHz over Intel's Turbo Boosted 3.9GHz.

Manually tuning the bclock, voltages and memory speeds resulted in a bclock of almost 107MHz using the 44x multiplier for a final speed of 4.6998GHz on the CPU and 2279MHz on the 16GB of system memory. Adjustments were made to the vcore 1.320v, 1.66v on the DDR3 memory, 1.05v for the memory controller and 1.81 for the CPU PLL voltage. Load line calibration was set to high and kept the vcore right where it was set during testing. Other than setting the memory primary timings the balance of the settings were left at auto. One area that is always a concern is overclocking recovery. On this board the overclocking recovery is as good as it gets and follows each of the boards from ASUS that OCC has tested with just a power down and restart required to get back into the BIOS with the last settings used still in place allowing you to change just a few parameters or go back to known good settings using the OC Profiles.

 

 

Maximum Overclock:

Each CPU and motherboard has been tested for stability at the clock speeds listed when in an overclocked state. These clock speeds will be used to run the test suite and will show the performance increase over the stock settings in the overclocked scoring.
