Noob here; need to OC Phenom II x4 965 to 3.8GHz - 4GHz - Page 4

post #31 of 47
3.8Ghz IMO is the best performance/heat

Just set the multi to x19, leave everything else on auto, you get 1.395v or 1.4v
100% stable and barely worse than 4Ghz, which you have to raise the voltage a lot for.

Leaving the vcore on auto will keep it at 1.31V or so no matter what I set the multiplier to. I've noticed that when others increase their multiplier, it automatically increases the vcore somewhat, even if that's set to auto. Why is this?

Also, while I can run 3.8Ghz stable, the power consumption does not throttle based on use, it stays at 111.30W instead of throttling down to 14.8W or so. Is there any way to keep it down even with an OC? I'm considering doing this: http://www.overclock.net/amd-cpus/55...l-n-quiet.html. Thoughts?

I've added Rep to all those who have helped me thus far -- thanks!

Ummm maybe just see how low you can get the volts and stable at 3.8Ghz - lower the better!
CnQ is pointless really, you want to save power turn off a light bulb. It will save more power.

I simply want to keep the power consumption down in order to keep the temps lower on idle (111.3W keeps it at 35-36C, while 14.8W idle is about 28-30C).

If power consumption (or temps) is your main concern go back to stock and turn on all the power saving features on.

I actually write down all my bios settings so I can switch between my OC and stock (for when I'm keeping my system up for days downloading/folding).

When we started OC'ing we threw power saving out the window. I'm currently sitting at 56 degrees C under load while in stock voltages (with safe multiplier increase) I was sitting at 46 under load.

I'm worried about the summer time though so I'll probably start setting a less aggressive OC for summer time. Maybe go back to stock. My apartment gets hot without AC.

Also the people who have motherboards who set the correct auto voltage usually have high end OC friendly motherboards.

If you got a cheap mobo (like I did) auto is complete junk. It just sets to stock settings.

Here's my overall point in regards to power consumption and heat output;

my brother recently OC'ed his 955 from 3.2 to 3.6 by only raising the multiplier. His CPU throttles down when he's not playing games. In other words, even though he has it OC'ed, it will throttle down and idle at 27C on a Corsair H70, and the power consumption drops to around 20W -- the lower power consumption is my main focus here as it will result in lower idle temps.

In my case, I tried OC'ing by simpling upping the multi--which is perfectly stable--but my CPU power consumption will consistently consume max power (111.3W) and will never throttle down even when it's idling. Why is this? I did exactly what he did, but I'm getting a very different result in the area of heat/power. His mobo is an ASUS M4A79XTD EVO, if that helps. My mobo is basically the Gigabyte equivalent of his.

Any help resolving this would be appreciated.

He could be running with the power saving features on.

If push all my stock settings (without upping voltage) and leave the power features on I'm stable. Any voltages changes + power saving = random BSOD's (when I'm assuming the power saving voltage aren't enough to power the system).

Problem is I can't get my NB freq's I want without upping voltage.

I'm going to try upping my FSB and playing around with NB voltage and see if I can stabilize on stock voltage on CPU and keep power saving on for summer time.

Yahs I got 3.75 ghz and 2500 nb freq with almost stock CPU/NB voltage and a massive boost in FSB freq/NB voltage. Hopefully this will stay stable.

It is advised when OC'ing to keep the power saving features off though.

If the power saving is what you really crave, go back to stock settings. Turn Cool n Quiet and the other power saving features on and push your system as far as you can go without voltage increases. If you get errors pull back and thats probably your limit.

On my X4 955 BE I got to 3.6ghz with stock voltage and was able to keep power saving.

But to each their own, good luck though!

Edit: Hah the 250 fsb keeps crashing. Wonder if its heat or a voltage issue.


Hey just realized your vid card. Hows the temp on the 6870 BE?

Yes, he does have Cool & Quiet enabled. I'll see how far I can push mine without changing voltages and without disabled C&Q and see how that goes. Thanks for all of the info!

EDIT: The other day, I was able to OC to 3.9GHz by only upping the multiplier -- and everything was stable. The only complaint I had about it was that I couldn't get the CPU to throttle down on idle, so power consumption was max on a constant basis (thus increasing idle heat temps; 28C idle to 35C). But, I'll play around with it and see if I can resolve that.

My XFX 6870 BE idles around 40C (ambient room temp @ 22C), and on load hits between 50-55C--depending on the game. Bad Company 2 usually causes the card to reach 55C, and outside of Crysis, that's the only game that pushes it that high.

You also need to turn on C1E support and theres another power saving feature on the bios I can't remember.

Afterwards you need to go to your Window's power saving options and set up up a profile.

Inside theres an option for min/max CPU voltage (or speed). Or just put the system on balanced or power saving and it should start working.

Most gamers put power settings to extreme which disables CPU downclocking.

If you find random crashes/bsod while using power saving mode, we'll need to start tweaking how much Windows 7 can ramp down the CPU. All the options are in the power saving settings.

Sorry just woke up and in search of food.

Good luck!

Summary since that was long, Bios power options do nothing without software (aka Windows 7 power settings).

Wow guess that vapor cooling does work. I have about the same ambient and I'm peaking at 73 degrees under Kombuster/Furmark. I tried breaking the 1000 mhz for the core on the GPU but temps were too high (after extra v to stabilize).

Most gamers put power settings to extreme which disables CPU downclocking.

If you find random crashes/bsod while using power saving mode, we'll need to start tweaking how much Windows 7 can ramp down the CPU. All the options are in the power saving settings.

Sorry just woke up and in search of food.

Good luck!

Summary since that was long, Bios power options do nothing without software (aka Windows 7 power settings).

Wow guess that vapor cooling does work. I have about the same ambient and I'm peaking at 73 degrees under Kombuster/Furmark. I tried breaking the 1000 mhz for the core on the GPU but temps were too high (after extra v to stabilize).
I decided to turn of all power saving features in the bios, as well as put my windows power setting on High Performance. Then, I upped the multiplier to x19, giving me a speed of 3.8GHz. Just ran IntelBurn Test for 3 minutes, as well as Prime95 for 5 minutes, and the max load temp peaked at 49C (idles @ 33.5-34C). How does that sound as far as temps go?

Also, I guess I was a bit unrealistic thinking I could have both a good overclock as well as low power consumption/heat output -- so I think I'll leave it OC'ed as long as ambient temps are low (since it's winter). But because I live in Arizona, once we hit summer and outdoor temps reach 105-113F (ambient room temps ~78F/25.5C), I may end up going back to the stock settings to keep the load temps down.

Thanks for the help thus far! I really appreciate it.
