WiFi card boosts ThinkPad X61 speed by 33%

Just replaced WiFi to Dell 1506 model and received free 33% on FSB, RAM and most important CPU. Dual IDA works as well. Now it's runs min 1Ghz and max 2,6Ghz dual core and 2,9Ghz single boost. Ram runs at 888Mhz CL5 and FSB 266Mhz.

It was nesesery to play 1080p videos coded in H264 and smooth video on dual screen in presentation in LibeOffice.

I passed MemTest86 few times so do CPU Linux stress test.

First of all it was unstable switching power modes in speedstep settings on BIOS.

I found that crashes causes by power management (some as OC in desktop) and I turn off "automatic" in CPU, PCI bus and PCI Express.

Now everything is working smooth, fast and stable. I can't change EPROM of my rams so I left it working on 888Mhz insted of 714Mhz that is possible to achieve in worse DDR.
