Anyone having trouble with enabling C1E on their systems? I got an Athlon II X4 630 (Propus) and C1E is giving me problems. With it enabled, Windows 7 won't boot half the time, and when it does, Prime95 is not stable. None of this happens with C1E disabled. Is this a CPU, or motherboard problem (Asus M4A785TD-M Evo)?

Also, what temp programs is every using on their AMD CPUs? It's been a while since I had an AMD system, my last one was a Opteron 165. Back then I would use CoreTemp, and IIRC, it would report the actual "core" temperature. Correct me if I'm wrong, this no longer seems the case.
 
Your C1E problem sounds like a BIOS issue. Make sure you're using the latest.

For temp reading, most programs will read the core sensor. Most will read from multiple sources, but will label them for easy reading. I use Open Hardware Monitor, which acts a like lot HWMonitor. Make sure you're looking at the "core" temp and not the "CPU", which is actually the socket.
 
The instability happens with both the BIOS it shipped with, and the latest. That was actually the first thing I thought too. I forgot to add, this is all on stock clocks.

I'll check out that Open Hardware Monitor, thanks.
 
yeah sounds like a bios issue either setting the voltage way lower then it should be when downclocked to x4 multiplier or something else id just leave C1E disabled for now..
 
Then I have a great program for you. If you can't find a way to enable C1E, download PhenomMsrTweaker. It's a software version of Cool 'n Quiet. The advantage is that you have complete control of how slow you want it to idle at and what voltage to use. I have my system set up to run at 1.5Ghz/0.98v when idle, a step up to 3.2Ghz/1.25v for increased demand, and a top speed of 4.0/1.48v. It works just as good, if not better, than AMD's power saving set-up. By default, you'll have 4 power states to use, but you can lower that if needed.

I've got the same cpu and mobo. I have C1E and CnQ enabled. Never had any problems. The highest stable overclock is only 3.3GHz (236x14). Any higher than this is unstable for me. I'm using speedfan for monitoring and k10stat for undervolting and underclocking.
 
After not being able to get it Prime95 stable, I just decided to leave it as is. Now today I tried to scan my system for viruses, and the computer rebooted. I got a message during POST, "overvoltage fault" or something like that. I then decided to manually set all the voltages, but no matter what settings I use, I can't get it stable. Prime95 won't even run for 10 seconds, I get either a BSOD, or the system freezes. Sometimes it'll just BSOD while booting to Windows.

I'm guessing I just got a bad board?

+1 PhenomMsrTweaker rules.

Disable CnQ in your Bios and use this. Its simply awesome.
I am using this with my C3 Athlon II X3 440 unlocked as Phenom II X4 B40 @ 3 GHz 1.2000V prime stable and 1 GHz @ 0.7200V (TDP 11W!!!)
I use only two P states out of the 5 possible.
 
I cannot recommend anyone enable C1E on an AMD platform. Last I tested, C1E kills SSD performance for some reason on AMD systems. There have been several BIOS revisions, so it could have been fixed. I also saaw posts on the Internet mentioning the same thing across other brands and models of motherboards.

I don't know what C1E is exactly, but I do know that I will never enable it. On a non-gaming system however, I would enable CnQ.

Did you run a memtest? Try that.
 
Yes memtest passes. Only when the CPU is on moderate to heavy use, it freezes. I also tried disabling all but 1 of the cores in the BIOS, same result. I requested an RMA, hopefully Asus approves.

One thing I found out, while I was checking for anything overheating, I touched the SB heatsink and it was hot, 58C according to my infrared meter, and for some weird reason, pressing on it just to just very slightly bending the motherboard crashes the system. Not just pressing the SB heatsink, but anywhere around that area. The only thing I can think of is bad traces on the board.

Could be, I had an asus mobo from newegg that if I bumped the case it would bsod, turns out it was a faulty ram slot that worked but any vibration would cause it to lose a connection somewhere.
