I currently have a Lenovo D20 Thinkstation 4158 (dual socket Xeon) with a Phoenix Trusted Core BIOS. I would really like the ability to overclock this board in order to get more performance out of my X5690 processors. I have searched the internet and it appears this has yet to be accomplished. If anyone is able to modify my BIOS to give me the ability to increase my clockspeeds i'm willing to compensate them for their time $$. Here is a link to the BIOS from Lenovo's website: h ttp://support.lenovo.com/us/en/downloads/ds014087 If you need any more info please let me know. Hoping someone here has the ability to get this done Smile.
