Test Setup & Overclocking
To ensure that all reviews on Overclock3D are fair, consistent and unbiased, a standard set of hardware and software is used whenever possible during the comparative testing of two or more products. The configuration used in this review can be seen below:
DDR2 Motherboard(s)
XFX nForce 780i SLI (780i)
Asus Maximus Formula (X38)
Asus Striker II Formula (780i)
DDR3 Motherboard(s)
Asus P5E3 Premium (X48)
Asus Maximus Extreme (X38)
• Intel Core 2 Quad Q6600 "G0" 2.4GHz 2x4MB
Memory Modules
• Cellshock PC2-6400 @  DDR2-800 (4-4-4-12)
• Cellshock PC3-14400 @ DDR3-1066 (7-7-7-20)
Graphics Card
• Sapphire Ultimate X1950 Pro 256mb PCI-E
Hard Disk
• Hitachi Deskstar 80GB 7K80 SATA2 7200RPM 8mb
Operating System
• Microsoft Windows Vista Ultimate (Latest Updates)
During the testing of the boards above, special care was taken to ensure that the BIOS settings used matched whenever possible. A fresh install of Windows Vista was also used between switching boards, preventing any possible performance issues due to left-over drivers from the previous motherboard install.

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
• Sisoft Sandra XII 2008c

3D / Rendering Benchmarks
• Cinebench 10
• 3DMark05
• 3DMark06

3D Games
• Quake 4
• Bioshock
• F.E.A.R
With the P5E3 Premium having probably the most advanced power delivery system of any board we've tested to date and a BIOS with more options than you can shake a very large stick at, the board certainly looks like a good candidate for being a top overclocker. So without further ado, let's see what its capable of...
Maximum Overclock
The Asus Maximus and DFI Lanparty boards have always been favourites of mine for for their ability to take a CPU to its overclocking limits. However, the P5E3 Premium totally blows them out of the water, managing to squeeze an extra 100mhz out of our Q6600 CPU with 1.5vcore. Similarly the board also beats out its elder X38 based "Deluxe" brother by 60mhz.
Maximum FSB Speed
With many of the lower-end Intel processors showing great overclock potential but often being crippled by low multipliers, having a motherboard that can obtain high-FSB speeds is a must. By reducing the multiplier of our Q6600 test CPU down to x6, the maximum FSB speed we was able to obtain from the Premium was 491mhz.
While 491mhz may not seem a great achievement where FSB speeds are concerned, the average Q6600 chip tops out at around 500fsb regardless. With this in mind we also tested a QX9650 ES chip we happened to have in the office at the time and managed a slightly more respectable 527mhz FSB.

Wow nice overclocking, i read somewhere that x48 is just a die shrink of x38, is that true?Quote

Yeah, IIRC it's a shrink from 90nm to 65nm and obviously has support for 1600mhz FSB. other than that they are pretty much the same.Quote
