I have nowhere else to turn. Hopefully you guys can shed some light for me. This is kinda long, but I tried making it short as possible.
I have an ASUS M3N72-D SLI mobo with an nvidia 750 chipset. It's an AM2+ board. My original cpu before the problems started was an original Phenom 9850 2.5ghz. Everything was working fine.
After checking bios updates on ASUS's site, they have an 0701 update that supports to AM3 Phenom 955 3.2ghz cpu. Naturally, I jumped right on it and bought one. That's when the problems began.
I flashed the bios, reset my cmos and for some reason CPU-Z is only reading my clock speed at 800mhz. I've read into this as much as possible and tried everything including making sure Cool n Quiet is off. Now pay attention... my bios is showing my cpu at the correct speed of 3200mhz. My 64bit Vista shows it at 3.2ghz as well. CPU-Z is only showing it at 800mhz.
Even under full load, I've monitored my clock speed and it does not go up... in case it is conserving power or what-not. My Windows Experience score dropped from 5.9 to 4.8 once i put the Phenom II in. Also, numerous benchmarks including 3dMark Vantage have suffered massively since this cpu upgrade. Note: my benchmarks also show a 3.2ghz clock speed.
Even though my bios and windows are reporting the correct clock speed of 3.2ghz, numerous tests and CPU-Z all point the other direction.
I've flashed the bios from the one that supports the new Phenom, to the one most recent available.
ASUS tells me the only option they can think of, besides what i've done already, is to re-install my operating system. I did that and still the same.
Now wait... it gets better...
Frustrated, I put my original Phenom back in and now... it's doing the same thing that the Phenom II did. My clocks in the bios and windows report correctly, but now cpu-z only reads it at like 1.2ghz. And my system is slower than ever.
With both cpu's, i've tried manually changing the bios settings from Auto to the correct multiplier, etc.. Remember... bios and windows show correct clock speeds, but it's not running that way at all.
Before any of this with my Phenom 9850, everything was great. My benchmarks were through the roof, my windows experience score was topped out at 5.9 and games ran great. Since messing with the upgrade and reverting back to my original setup and original bios, everything has been downhill ever since.
My motherboard is only a few months old and I don't want to have to buy a specific AM3 board if ASUS claims that their 0701 bios update can run the Phenom II 955 cpu.
Also, numerous people with the same board and cpu have flashed their bios and it works fine for them. So i know it's possible.
ANY help would be greatly appreciated. You guys have always been more help than any customer service. THANKS!!!!!!!!!!!!!!!!
UPDATE: My cpu-z shows my Phenom 9850 2.5ghz cpu running at 1.25ghz with a 6.25 multiplier. Exactly HALF of the stock settings. Everything is set fine in the bios and windows/bios sees the full clock speed. its only performing like a 1.25ghz cpu. coolNquiet and all other power features in bios/vista are turned off.
Any ideas?
