Updated Signature code: This sig looks a lot better than the bland one I put together. Special thanks go to Foxy@OC'D for making it and allowing me to post it here for everyone to enjoy.

I haven't seen a thread like this so I decided to make one. This will be a thread to discuss the phenom II x2 550: overclocking, unlocking cores, general discussion, etc... I will make a spreadsheet on google spreadsheets of overclocks achieved and give someone else permission to edit it if they want to help.
If submitting an overclock, please include the following (this order would help too for organization): Clock speed
FSB x Multi
Vcore
RAM speed
NB speed
HT Link
Motherboard
Cooling method
CPU-Z validation would also be nice. http://spreadsheets.google.com/pub?k...en&output=html
vnv727 is now helping with the chart. Thanks to him very much! I am no longer updating this, PM me if you would like to be able to edit it on google docs along with vnv727. Unofficial Phenom II x2 550 Club!
Thread now under new management. ENTERPRISE
Tator Tot EDIT: Thread now under VNV727's control.
Clock speed 3.7ghz
FSB x Multi 200 x 18.5
Vcore 1.385
RAM speed 800 mhz
NB Speed 2000 mhz
HT Link 800 mhz
Motherboard asus crosshair II
Cooling method stock cooler
anyone know if im able to unlock the 2 cores with a crosshair 2 780a. im not sure what you need to do to see if you can. i kno its only first poissible if the 2 cores are just dsiabled but not sure if i need to downlaod any software

No, you can't. nForce motherboards don't have a real form of ACC.

I think some other user did this by enabling NCC (nvidia's form of ACC).
Hopefully by today I should have something to show. Right now I'm at 3.9ghz with 1.47v and load temps don't seem too bad. So far the highest that I have seen are 45°C. The problem is that the last couple of bumps have needed a lot more vcore, 4.0ghz isn't looking to good right now.

Are you using Vista 64-bit? I think you are at the limit for 64-bit.

It's actually called NvCC which stands for Nvidia Clock Calibration. It's a form of ACC for the Nvidia nForce 980a only. But from what I've read it uses a separate micro code from ACC that does not allow unlocking.

There's an overclocking limit due to OS? I don't know if that's true or not, but you are right about the limit. 230x17= 3.91ghz, which is pretty much my max, somewhat stable clocks. I have booted over 4ghz but not stable.
Right now I'm trying to work things out using a 16x mulit to try and increase the reference clock. I just don't know how much voltage is safe for the cpu/nb. I'm still trying to figure that out. If I can do 245x16, I'll be happy.
