What is the maximum voltage I can give to my CPU?

[DoubleROFL]

Just wondering what the max amount of voltage I can give to my processor.

I dont want to give it so much that it will cripple the life span of it.

The stock voltage is 1.3V.

Thanks!

you should be safe up to 1.45...just watch the temps.

I have it at 2.84Ghz, 1.45V.

I am surprised it's only at 39C under FULL load on the STOCK HSF!

I keep it at 2,9 ghz at 1,5V. Before I upgraded to 4 gigs of ram, using 4X1024, I use to keep it at 2980 mhz with 1,52V. But I have good air cooling for that. You shouldn't use more then 1,45V like Tweakin said on the stock cooler.

That's a nice OC for that processor.

I never really know how much voltage I am feeding my X2 3600+ Brisbane... it must be my motherboard, but reported voltage in programs like cpu-z is much higher than what is in BIOS. Usually reported voltage is lower because of vdroop, but mine is higher... For example, @ 2.8GHz w/ 1.4V in BIOS, CPU-Z reports it as high as 1.52V under full load. Right now running @ 2.6GHz w/ 1.325V in BIOS, it reports 1.36-1.39V just in idle and 1.408V under load.

And of course w/ Brisbane you never know the core temp either, but the CPU temp is pretty low (I have an Arctic Cooling Freezer 64 Pro).

There has to be something wrong there. I think it's almost impossible to have 39C on stock cooling and with 1,45V. Mine gets to 55 C with 1,5V with a Thermalright Ultra 90 with dual 92 mm fans.
What program do you use for temperature monitoring? Speedfan ,for example, reported temperature in idle under the room temp, which is impossible.

I use Core Temp and HWmonitor

And CoreTemp works on your Brisbane? It shows 8C on both my cores...

Not that I'm worried about overheating. I overclocked my 4400+ to 3.0GHz on 1.23V and power consumption was about the same as on stock 2.3GHz with 1.34V. I use a Ninja, but even a stock HSF should be able to handle it just fine.

Old-ish post, but I saw it through a Google search and just thought I'd drop a comment. Reached 2918MHz on mine at 1.4V still with the stock cooler this morning. It is winter though... lol nonetheless, I think its rather good. Currently its at stock 1.25V and 2.8GHz (bus 267MHz) and running great. For anyone who is having trouble with HWMonitor, CoreTemp, etc and the AMD Brisbane CPUs, here is a pic of my temps via HWMonitor after running HyperPi (this was done with Opera and a few other apps in the background so the Pi score is a bit low):

Note the highlighted line; thats my CPU temp. Easiest way to find your CPU temp if displayed incorrectly is running a benchmarking app and monitoring for rising temperatures. In my case SuperPi, since its not full-screen.

CoreTemp reboots my system though...

So what's the temperature inside your room? 10-15 Celsius?

I see that you use an Asus motherboard. Asus Probe works great for Brisbane X2s. It gives you the "real" or at least the closest value to the real temperature.

Didn't really understood your post. You've used Hyper Pi to load your cores and record the delta value. So? If Hardware monitor starts from a wrong idle temperature, then your temperatures are still off the real value.
Also, Super Pi doesn't really tend to maximize your core temperature. Programs like Orthos or Prime 95 does a better job in heating up your cpu.

Don't know exactly what the room temp was, but it was pretty close to 10'C lol we don't believe in heaters... I didn't mean max out my temperature per say, but I meant you can look at the specific temperature that is actually increasing while you are running the benchmark, however mudane. That would be TMPIN0 in my case and said temp agrees with PC Probe. So you can still use HWMon, SpeedFan, etc to monitor Brisbane, you just need to know which temp to look at.

I prefer not to install PC Probe though, because when I exit a fullscreen 3D app the monitor display panels are always out of order. As for maxing out my temps, I use either Orthos or another stress app I can't remember right now; installed XP x64 recently and haven't needed it yet.

So, in short, I don't look at the temp HWMon says is my K8 core. I look at the one that corresponds to PC Probe. In other words, the one which shows the temperature rising with the core stress.

If you have trouble believing my claim, here is the CPUz validator for it: http://valid.x86-secret.com/show_oc.php?id=373392

I know how it is, newbies butting in and grabbing numbers from their hats. Too bad CPUz doesnt show the voltage. But you can believe me if I say something about my PC, I never spin yarns and I have been overclocking since my Cyrix 233 lol Ran a Duron 900MHz (think it was a Spitfire) at 1044MHz but the P3 cooler I had kept me from going further.

Anyway, my whole object was just to tell anyone in doubt that you could actually monitor Brisbane with said apps.

I believe what you say, but your first post wasn't quite understandable. It's not that hard for a Brisbane to hit 2,9 ghz, that wasn't the "hard to swallow" part, but the 18 C your cpu had. But if you have 10 C then it really is that cold.
