Biostar MCP6P M2+ OC problems

[Bill Kunert]

I have a Phenom 8750 on a Biostar MCP6P M2+ with 4 gig of PNY 800MHz ram. If I raise the clock speed even 5MHz from 200 to 205 it will often give a message on boot that it is defaulting to standard frequencies. I've had it boot sucessfully at 2.8GHz and when it does boot it runs fine and will pass Orthos for over an hour. At that frequency I set the memory back to 667MHz. Is there any way to disable the function on this motherboard that causes overclock to fail? I've searched the forum and others with this motherboard are getting decent overclocks with, apparently, no problem.
Thanks

Bill, did you find the solution to your problem? I'm experiencing the exact same problem with this motherboard, I have a Athlon X4 620 which I'm able to OC from 2.6Ghz to 3.4Ghz, but I'm getting the "Warning, running in safe mode, resetting CPU frequency" error message occasionly, very annoying indeed. I have a 2GB PNY memory on the motherboard, which leads me to believe whether it's this specific memory that caused the problem.

There may be a connection between the thermal design of the CPU and this motherboards limit of 95W.

Both of your CPUs have a thermal design of 95W. I've read where some people installing a Phenom II of 125W had this mobo shut itself down after the bios delivers a message of exceeding the wattage limit with their CPU.

If you overclock you may be tripping a bios limiter which then undoes overclocks. I would think a voltage increase would be required to increase the wattage demand beyond 95 but I don't know how this bios is coded.
