Hi.. I've been experiencing some high voltages for my new 965be c3. I have to set them at 1.54volts in order to run 3.9ghz. Which to me seems very high. Is it my MSI 790GX-G65 causing this? Or?

I had a 965 3.9ghz that need 1.55v on 790FX mobo and on a 890FX mobo I needed 1.5v. Every cpu are different when it comes to ocing.

I wouldn't overclock too high on that motherboard. It has weak CPU power phases (4+1) and it has a background of dying when overclocking. It is most probably you're CPU. But I would set the multi to 19x and then try bumping up the BClk to about 217 to get 4Ghz, then slowly bump up the vcore until you hit 1.55v. Never go above 55'c core temp btw.
But like I said, I would highly recommend against overclocking on this motherboard.

Yeah.. I'm thinking of getting another motherboard... What do you guys suggest? Something that's not MSI?

Thats kinda high, I would suggest remounting the HSF and using a small pea sized amount of thermal paste on it

I would wait until Bulldozer (AMD's next gen CPU) comes out in June, then upgrade your CPU and Motherboard. Or just the Motherboard, as the Bulldozer motherboards (AM3+) will be compatible with current AM3 CPU's, such as the one you have. I would suggest looking into ASUS/Gigabyte's lineup of BD motherboards when they come out, unless MSI does something amazing

If you are looking to OC to 4GHz you'll need something with a better power design. I would recommend the ASUS M4A89GTD PRO/USB3... But if you want a good shoppable list
http://www.overclock.net/amd-motherboards/946407-amd-motherboard-power-phase-list.html?highlight=power+phase+list

Look at 8+2 Power phase and 140W TDP

If you want to try to future proof a bit look at ones that will support AM3+.

I don't know too much about them yet since we havn't got there yet, but something to look into.

Thanks a bunch with all of your help. I just did a bios update though, temperatures dropped a bit. They wouldn't even show up on AMD Overdrive. Only on Speedfan or CPUID HW Monitor. Now it's idling at about 35C.. Still high in my opinion. Everthing stock.. My stock voltage is at 1.4, you guys think I should lower it a tiny bit?

ASUS M4A89GTD PRO/USB3 or ASUS M4A89TD PRO/USB3 or BIOSTAR TA890FXE. All three are great mobo for ocing.

ASUS M4A89GTD PRO/USB3 has on-board video and 8+2 phase.
ASUS M4A89TD PRO/USB3 has no on-board video and 6+2 phase.
BIOSTAR TA890FXE has no on-board video, one of the best 4+2 phase (World recorder for OCING),3 PCI-E 2.2(x16/X16 or X16/X8/X8) and no USB 3.0.

Thanks for the info. Much appreciated.

I have the first version is the ASUS M4A89TD PRO/USB3 which has no USB 3. My 2 nephew and me are running on ASUS M4A89TD PRO and they oc great. One of my nephew is running a 965 C3 at 3.9ghz and I'm running a B55 X3 at 4.0ghz.

Wait lol, overclock your NB to 2400Mhz leaving the voltage on auto and lower your RAM timings. That will give you the best results

Then wait for BD and a BD ready mobo ^^

I've got them running at 1600, 8-8-8-24 with cpu-nb at 2600mhz @1.3v. Testing now will keep you updated.

CPU running hot is affecting the clocks (Phenom II can run lower volts when cooler - I proved this myself when I went from Xiggy DK to NH-D14 cooler. Temps dropped significantly and I was able to lower my 4Ghz voltage by 0.05V)
It is either (or both) a bad CPU cooler mounting (check the tightening) or the heat from the VRMs/MOSFETs is leaking to the CPU area
