CPU Upgrade With Worse Performance

I have an old Asus M3N-HD/HDMI motherboard in my rig, and I upgraded my Phenom 9950 BE, to a Phenom II 980 BE, and I have at least a 75% decrease in performance. I'm running Windows 7 SP1. I have the latest BIOS for my motherboard, which I reset to defualts. CPU Temps are at 30ºC. Cool and Quiet, and C1E are disabled. I enabled an auto 10% overclock in the BIOS, to 4.1 GHz, still dismal performance. I've tried both standard and auto settings in the jumper free configuration. Reseated my BIOS battery. CPU clock speed is right where it should be at defualt, 3.7GHz. I don't know what else to do. Is there something in the jumper free config that I need to take off auto, or standard? Or is it something else?

Check your temps and CPU speed. Zero chance it's 30c if it's actually running at speed. Use AMD overdrive and 2-3 other monitoring programs. Also use CPUz or MSI afterburner to confirm actual speed if CPU. Either it's thermal throttling, vrm throttling, or a driver is goofed up

I'll try that, thank you for the reply. I've been using Speed fan to check the temps, and Windows properties to check the clock speed.

I installed CPUz, it says the clock speed is 799 mhz with a 4x multiplier, 4 cores, 4 threads. Bios shows CPU temp at 27ºC, in Windows speedfan shows 30ºC.

I ran prime95 for an hour, with speedfan. Temps went all the way up to almost 35ºC. During the test I loaded CPUz and it showed the standard clock speed. So that ain't it. Interesting thing though, I ran another assessment of the WEI, and when it got done I got an error saying that it could not be computed, "due to an error being reported from the operating system, driver, or other compontent". That is the only error I've gotten, so I'm thinking a fresh windows install will do the trick. I'm waiting on a new HD to come in the mail, when I get that I'll setup a new RAID and do a fresh Windows install. I'll post on here what I find.

Well, I reinstalled windows. I still have dismal performance, my 3dmark 06 cpu score is only 1100, it should be over 5000. WEI is still 3.7. I'm at a complete loss. A fresh Windows 7 install, fully updated, having all latest drivers.

All cores are active. I think I've come to the conclusion that the problem is my motherboard, some AM2+ boards only run phenom ii chips at 800mhz. Mine is supposed to be compatible with this cpu with the latest BIOS update, also it supports up to 125w cores, which this cpu is as well. I even set an over clock to 7ghz by using a 35x multiplier. Windows even saw it as a 7ghz chip, but cpuz shows only a 4x multiplier and 200mhz clock. I turned up the clock to 500 mhz with a 20x multiplier, with the same result, cpuz showing a 200mhz clock with a 4x multiplier. I've also increased the core voltage up to 1.5v with no change at all. No matter what I do that chip is still only gonna run at 800mhz in that motherboard.

Well, I found out the solution, for me it was to just change out the motherboard. I guess it's just a fact, old AM2+ motherboards sometimes don't like ceetain AM3 chips.
