ASUS Maximus II Formula P45 Motherboard

Test Setup
 
Matching our previous reviews of P45 based motherboards, we used the same setup to guarantee a fair review.
 
 
During the testing of the setup above, special care was taken to ensure that the BIOS settings used matched whenever possible. A fresh install of Windows Vista was also used before the benchmarking began, with a full defrag of the hard drive once all the drivers and software were installed, preventing any possible performance issues due to leftover drivers from the previous motherboard installations. 

For the 3DMark and gaming tests, both single card and CrossfireX configurations were used for the purposes of testing the scaling of the P45’s 8×8 configuration.

To guarantee a broad range of results, the following benchmark utilities were used:

 
Synthetic CPU & Memory Subsystem
• Sisoft Sandra XII 2008c
• Lavalys Everest 4.0

File Compression & Encoding
• 7-Zip File Compression
• River Past ViMark

Disk I/O Performance
• HDTach 3.0.4.0
• Sisoft Sandra XII 2008c

3D / Rendering Benchmarks
• Cinebench 10
• 3DMark 05
• 3DMark 06

3D Games
• Oblivion
• F.E.A.R
• Call of Duty 4

 
 
Overclocking
 
Much like the MSI Diamond that we reviewed previously, the wealth of options in the BIOS need to be tweaked to get the very best out of this motherboard. While moderate overclocks were easily gained through the AUTO options and Level up configurations, better overclocks were accomplished tweaking the Vcore/NB/VTT voltages. Time constraints prevented me from delving any further into the GTL settings in attempts to eek a little more out of the board unfortunately.
 
Max Overclock (Air Cooling) Max FSB (Air cooling)
 
While not the best results we have had out of a P45 Board, an FSB of 500mhz and overall overclock in excess of 3.9ghz is certainly nothing to be ashamed of. Given more time, 4ghz should have been attainable without too much difficulty. I am in no doubt that the overclock could be pushed even with a little more voltage and various tweaks the board has to offer, but with the high ambient summer temps now in full force, we were limited in our air cooling performance and as such I had to hold back a little. That said, the Maximus II Formula certainly proved to be a worthy overclocker’s board and can most definitely push the envelope with regards to getting the most out of a CPU.
