1.7v! :(

post #1 of 16
Thread Starter 
I downloaded PhenomMsrTweaker to try to overclock only one core for SuperPi. I re-booted to adjust the voltages one last time in BIOS, seting them to 1.4935V for 4125 (250x16.5).

I get to Windows and I notice it's very laggy so I open HWMonitor to see my temps and voltages. Idle temps are 50 C and voltage is fluctuating between 1.65-1.7V I immediately shut it down to avoid damage. In BIOS I then dropped the voltage and clocks down to near stock and booted up. Still at 1.6-1.66V

I figured it was PhenomMsrTweaker fighting with the BIOS voltages so I only ran it at those volts long enough to uninstall the program.

What are the odds of any degradation or damage? Also, I'm thankful I didn't blow a MOSFET.

The odds of damage are very low, to non existant, thats a fraction of the time required to degrade the chip. You'll be fine.

This seems to happen alot to asus boards when you use a voltage controller outside the bios.
run your max overclock under prime 95 24 hours straight. thats the only real way of telling if there was any damage.

Props to you for quick thinking. However, you should have booted up in safe mode to uninstall the program, rather than uninstall it from a normal bootup with the offending program running and still beating up the cpu.

All chips take voltage differently, and on top of the way they take voltage as it is increased isn't linear at all. However, at that high volts they either make it or they don't. If it still works now, it's probably fine.

Okay, good. Now that I think about it, I should have been a lot more worried about the MOSFETs than the chip...

Alright, looks like I'm going to be stressing it today.

Thanks, temps and voltages are what I always check first if I run into problems/lag. I'm not too familiar with safe mode. I know of it, but what exactly is it?

My chip has probably the most non-linear voltage line ever. 1.365V for 3.8GHz; 1.45V for 4GHz

Program's now uninstalled and voltages are back down to ~1.44-1.46V, no lag or other problems.

I wouldn't be too worried about it. I've ran my athlon II at 1.65v before for longer than you did, running prime. Still runs fine months later.

Everyone always says 1.55v for phenoms (Which is what -amd- says is max recommended for OC'ing) but some people go as far as 1.6v with no issues.

For such a short period with no load it's fine. Also, ASUS boards usually have VRM protection that shuts the board down before causing damage.
AMD, I give up.

Yeah I figured that if I was really going to hurt the system it'd shut itself down first.

That's ridiculous! Did you have any special MOSFET cooling?

Ohh wow, that's crazy! But you at least have a really nice board! I've got an 8+1 unheatsinked MOSFET board...

The way PhenomMSRtweaker works, the "voltage adjustments" are calibrated to what the stock voltage is, but won't calibrate to whatever your increased (BIOS) voltage is. Which means if you set it to whatever voltage in MSR tweaker, it is basically BIOS voltage * MSRtweaker voltage, or something along the lines of that. I used to use K10Stat (similar) for custom cool'n'quiet operation on my x4 before, but in order to have correct voltage settings, I had to keep the BIOS-set voltage to stock.

Better to set the voltage in your BIOS, even if clocks are set to something else.

A good board will either handle the Phenom II x6 at 2V just fine (i.e. on DICE), or will downclock/throttle/protect itself if too high voltage/clocks/power consumption over stresses the VRMs (which should be the case on OP's mobo as ASUS normally features this OCP protection)
