WinRAR 3.9 x64
This benchmark compresses our AT workload consisting of a main folder that contains 954MB of files in 15 subfolders. The result is a file approximately 829MB in size.
Microsoft Excel 2007 SP1
Excel can be a very powerful mathematical tool. In this benchmark, we are running a large Monte Carlo simulation on stock pricing data to estimate the riskiness of an investment portfolio.
Adobe Lightroom 2.4 x64
Lightroom is a quick and easy to use program for batch conversions on digital photos. We perform a standard conversion of 50 RAW images into the JPEG format.
Bibble 5.0
We utilize Bibble Labs’ Bibble 5 v2 to convert 50 RAW image files into full size JPEG images with the program’s default settings. This program is fully multithreaded and multi-core aware.
Windows Live Movie Maker
We utilize our standard HD video file, add music, and start/ending transition effects.

The PCIe lanes coming off the P55 are 2.0, the problem is that they are running at 1.x speeds (2.5GT/s). On these two boards, the x16 slot is off Lynnfield and will not be affected by any card placed in the x4 or x1 slots off the P55.Mr Perfect - Tuesday, October 6, 2009 - link
I should probably know this, but what does a 2.0 slot running at 1.x speed bring to the table that a 1.x slot doesn't? Does it provide more power or something?MadMan007 - Tuesday, October 6, 2009 - link
Yes I was half right with my post and nothing Gary said was technically wrong it's just misleading. They are PCIe 2.0 spec slots but running at half speed, this is clear from Intel's chipset disgram. It's really a farce to call them PCIe 2.0 though because the overridingly most important change from 1.x to 2.0 is the double bandwidth, there are other changes like the power rating I believe and maybe some low level changes but nothing major. I think it's false advertising to call them PCIe 2.0 personally because they don't fully conform to the spec.In any case I'd still like to know how many lanes the main CPU-based slot retains when a 1x or 4x card is placed in a secondary CPU-based PCIe slot. Anandtech seems to be more receptive to odd little investigations like this so I hope Gary will check it out.
