here's the guide

Ehh if he has already said that its unstable at over 1.5 volts how is decreasing the volts at this point going to help? Dont see what your getting at here

Max temp on your chip is 62 so I would say your at your max temp really before heat causes instability

Maybe decrease your NB clocks and see if you can lower the CPU-NB voltage a little as that increases heat.

hope you anit talking bout my chip anyway,

Say at 1.50v . i still think it is too much but...

Dont get what your saying? Were not talking about your chip?

Phenom II's can take 1.55 volts with good air cooling and 1.6 volts under water however they like to be cold more than volt pumped esp C2's.

OP - Reduce your CPU-NB voltage if you can and lower your NB clock that may help with stability and lower temps

Most Phenoms start becoming unstable at 55C (i experienced this). 62C is AMD's max temp. before you risk damaging it (although this is probably quite conservative).

OP would probably see better performance with a lower clocked cpu (to reduce heat) and keeping NB clocks where they are or going higher. (e.g. 3.7ghz cpu/2.8ghz nb is better than 4ghz cpu/2.4ghz nb)

CPU/NB is at 2.6GHz right now. @ 1.35V. Is that too high?

This is true however his has gone to 57 and my 720BE used to become unstable long before that so I thought it was worth bringing up

I agree with this however I would suggest trying to lower the CPU-NB voltage as that will increase temps quite a bit.

yes, but i wouldn't reduce that nb speed/voltage in order to reduce heat. you would be better off reducing your multi by one or two allowing you to drop voltages/heat. phenoms get huge performance boosts from NB ocing. mine is currently at 2.6ghz @ 1.184v.

max nb voltage is same as cpu. 1.55v so you are good.

CPU -NB voltage will contribute a lot to heat and overall stability so trying to undervolt it will help if you can keep your NB speed up.

However OP I think you should just stick with your current clocks ans its going to be a very minor increase in performance if any

Man that h70 should be getting better temps. I have an a70 the air cooling version of corsair high performance cooling.
I am running my be 720 x3 unlocked to an x4 at 3600 1.55v and nb at 2600 1.47v and I never hit over 55c running prime for 4 hours and then intel burn test and linx might tap 57c.
You should reseat your cooler and maybe get a set of good fans that have high cfm.

I strongly suggest that you keep the cpunb overclock. I'd rather drop my chip to 3.7Ghz and lower the volts then run my cpunb at stock....
