This is Patently Ridiculous...

[blankets]

So i just built a new system, phenom x3 720 BE with a hyper 212+ cooler. i unlocked the 4th core, tested stability, and then decided i should probably find out the temperature offset between my TMPIN0 and TMPIN1 and the actual CPU temps because after you unlock it, CPU temps for the cores no longer work

i used HWMonitor for temp monitoring.

When i re-locked the core and got the temp monitors again, i got some Very interesting results...

wtf? 36 load? the picture doesn't show it but i have OCed it to 3.5 Ghz with a core voltage of 1.45 V

to make it worse, when i let it idle, the temps went down to 23 C. I don't live in antarctica. it is room temperature here. This is Impossible.


i presume this is something wrong with HWMOnitor?

Normal room temp is around 20c = ~72f. 0c is freezing.

 

[Ben90]

Ive known HWmonitor to be very off. Try something that tells you the TJmax directly.

Could be right actually, when I first bought an x3 and wasn't overclocking I had idle temps of 16 to 18c on cool days. My x3 idles at 20 to 22c @ 3.73ghz, that's just cool and quiet downclocking the cpu. At full load I hit 46c, 48c if its hot out. As for your load temps, you're not really pushing your voltage that high. 1.45v is more like 1.425 actual on a lot of boards so this might be contributing to the lower temps. Its also a fresh build, temps might go up over time.

That's not very long into the test, and prime95 is not the most stressful either. I'm getting one of those 720s delivered really soon and am planning to stock cool it so I like hearing this if it ends up being accurate.

I took that picture a bit early into the test. i ran it for an hour and the temps never fluctuated from 36 C.

on a semi-related note to that, i'm overclocking it with 4 cores unlocked. do you think 1.5 V is too high in terms of cpu degradation?

i know amd's site says that the x3 720's max safe voltage is like 1.425 but other forums have posted that anything under 1.55 v should be safe for phenom 2 x4's. thoughts?

Correct - HWMonitor is not useful for core temperatures.

is there a good monitoring program anyone would suggest?>

real temp

however for me HW mon is never more then 2 C different then what real temp says

real temp does not support amd cpus.

I used coretemp and it still says 36 under load.

i tried using orthos with core temp and it says 32 under load...

should i just not look a gift cpu in the mouth?

 

[Accord99]

I think this is probably the cause:

The AMD temperature reading needs an offset to be accurate but that value is unknown.

I have a 720BE too and noticed the same thing with HW monitor. I have a Xigmatech S1283 cooler, which is roughly comparable to yours, in a HAF32 case.

My thinking is that's WAY better cooling than stock and, at minimum, more than sufficent to cool even an unlocked overclocked 720, especially if your case has good air flow. So I set a fairly cool CPU temperature cutoff point (80C) in BIOS in case the fan stops for some reason and so the CPU doesn't go to it's (much higher) internal temp. cutoff point and don't give it much more thought.

I used to do video encoding on my main computer and had the 720 on four cores at 3.5 ghz, but now I have a 720BE in a second computer oc'ed to 3.5ghz, though only with three cores active, and I've done continuous days of video encoding, which kicks cpu utilization near 100% on all three cores and never had a problem and that on a Xigmatech Rifle 90mm cooler.

There's no way that the individual cores under load are going to be less than TMPIN0. The 36C figure is incorrect, and if I were to guess it's probably closer to 48-50C.

AMD stated 1.5v is safe on the SOI process at one of their overclocking events, you certainly don't have to worry about voltage like you do on Intel chips. Of course, most would tell you more voltage will shorten the lifespan to some extent; but in terms of consequence I highly doubt you'll be running that chip by the time you notice any.

Worst case, you take a few years off the top of the chips lifespan. With cool and quiet my chip doesn't really see full voltage half the time it's on anyway, so if you plan on browsing the internet as much as you do anything else with your computer the picture should be the same for you.

Realtemp gives me the most (seemingly) accurate temps for my Q8200. Most likely it's just as good on AMD boards.

If you want to test your CPU/RAM, use Linx. It's the only stability app I use because it find errors really quick.

Could be a BIOS issue. Sometimes manufacturers release an updated BIOS to deal with funky readings coming from their boards- I'd check that. If that's the case, no matter what app you use it'll give you the same reading as what the sensor is telling the OS even though it's wrong.

the bios is fairly recent and i am hesitant to flash my (otherwise) working bios. i guess i'll just keep an eye on the tmpin01
