nc8430 and NHC

The NHC temperature monitor seems to be acting a bit funny - the CPU temperature reading seems to jump straight from 70C to 80C with nothing in between. Looking at the status panel, it shows 70C and three more temperatures in parentheses ... anyone have any idea what those are? See screenshot:


I'm speculating that the three readings in the parentheses might actually be CPU, HDD, GPU or some such, and the "70C" is just some formula-based 'combination' reading, which could explain the jumps ...

 

That's really weird as on the nx6325 RB526UT#ABA I only get (2) readings in brackets.

Mine for example right now running with Prime95 running the cpu @ 100% says:

CPU TEMP: 49c (57, 23c)

nx6325 RB526UT#ABA is a single core AMD Mobile Sempron 3400+ 1.8GHz - cpu:

HOT DEAL !!!! $500 after $100 HP mail in rebate. This unit being priced normally at $975

The two readings in the brackets, the right lower one is the starting temp, the one on the left the highest temp.... The temp out besides where it says CPU TEMP: is the current temp.

The temp on mine increasing in 1c steps...


Sounds like you need to send in a bug report to the author, as your "current" temp is more than the other values.

Pull up the translucent display and see what your temps are there. I would assume it would show both cpu cores, and the current temp (click the little arrow button under the picture of the laptop)


PS: Mines showing the hd temp as 37c... Looks like you need to contact the author of the program.

 

Hmm .. thanks for the reply; (max, min) does make sense. Maybe the third reading is an average? Still doesn't explain how the reading outside the parentheses could be higher than any of the inside ones. Although ... right now it's showing 55c (50c, 52c, 56c) which isn't consistent with (max, min, avg) either ... I guess a bug report is the way to go.
And yeah, my HDD temp is just plain not showing up.
I think I'll download MBM5 and see what that says, maybe it'll clarify things.

 

You might have seen it already, but they were discussing about the NC8430 bugs in the official NHC forum ( http://www.p35-forum.de/board/board.php?boardid=70).

Also in the german speaking section in english, check it out here:

Scratch the MBM5 - I never noticed it hasn't been updated for two years .. lol. Pity, it was a good program.

Thanks for the forum links; I looked around, but I couldn't find the english section myself... I'll check it out.

 

I'm getting wacky temperature readings too, on my nc8430. It's calling the HDD temp 0C and the CPU temp 70 (idling) which seems very wrong since the laptop isn't even warm.

It says TZ4 is the zone with the CPU, for what it's worth.

 

Try out Everest...NHC seems to be having problems. I'm starting to wonder if it is because of the SATA drive...?

Everest reports much more sensible temps

 

News for the NHC forum ( http://www.p35-forum.de/board/thread.php?postid=48314#post48314)

"PS: I have also lowered the CPU voltage via the NHC and it works pretty good. Going from approx. 1.27V to 1.05V at full speed (2GHz) and the temperature under full load went from about 72 to 59C, which is a big improvement!"

Q: "Oh nice! I guess this means the laptop will run at slower speeds..."

A: "No, the CPU will run as fast as before (2GHz for me). The only difference is that when switching to the highest speed, the motherboard will not rise CPU voltage to 1.27V, but only to 1.05V, which means lower power consumption, lower temperature and higher battery life. You can set voltages also for other speeds (except of the lowest 1GHz)"

Sounds like things are improving...

 

I get similar tiered temps on Linux. They seem to be correlate more toward Fan tiers (when they hit a new level, fans tend to kick on).

Other temp sensors match more closely CPU, GPU, and eI believe the battery.

 

Everest (even though it helpfully warned me that it doesn't yet fully support my chipset the "Intel Calistoga i945GM/PM", it gives me idling temps of 55-57C for my CPU which is much more believable than 70C (which the P4 in my XPS didn't regularly reach)

 

Yes, it is improving. If you download the ACPI file from here, you can also change fan speed and make the nc8430 a bit quieter (and warmer). Now the guys from NHC are trying to make the possibility to change also the temperatures, at which the fan should kick in, but this doesn't work yet.

For measuring of processor temperature, I suggest using the Core Temp utility (simple EXE, no installation), which can be downloaded here: http://www.xtremesystems.org/forums/showthread.php?t=103638

 

Thanks, core temp and RMclock both show idle temps around 51-52C, which didn't match ANY of the four temperatures being displayed by NHC. Also, the VID settings on both of them don't match the ones displayed by NHC:
NHC shows voltages from 0.95V to 1.15V
RMClock and CoreTemp show 1.062V to 1.262V
The range is 0.2V total in both of them, but which one is correct?
Anyway, I'm switching to RMclock from NHC for now - the temp monitor is WAY more accurate, and the program itself is lighter.

 

Is there any possibility to control also fans from the RMClock program?

 

Nope, no fan control, just CPU voltage and throttling, power settings, battery monitoring, etc.

 

fooling around with RMClock I don't see any way to switch the speeds dynamically...am I not seeing it? I see that I can set a CPU speed and voltage, but it stays at that speed and voltage no matter what?

 

Simple tutorial:
Run RMClock.
Click on Profiles.
In the "Profile Selection" box select a profile for AC and one for battery power. (I just use "Performance on Demand" for both).
In the Master Performance State Table turn on all the multiplier checkboxes, click on the first one (6) and the last one (12) and select your desired min and max voltage, and make sure "Auto-adjust intermediate VIDs" is enabled.
Click Apply.
Now go to the Performance on Demand profile submenu (or whichever one you used).
Turn on "Use P-State Transitions (PST)" and "Use Throttling (ODCM)", and turn on all the index checkboxes underneath them.
Switch to the "Battery" tab on the same page and repeat. Click Apply.
Now go to "Advanced CPU Settings" and turn on Thermal Monitor 1 and 2, and check the "Apply these settings at startup" box. Click Apply.
If you want to make these settings stick, go to the Management page and click the "Run application automatically when Windows session starts."
That's it!

 

It still seems that nhc has problems monitoring the nc 8430 but it's also the only way I know of to regulate fan speed... so I guess I'll keep using it.

Does anyone have a good acpi file to share with the latest bios settings for the nc8430 ?

 

Two questions:

- Does anybody have the ACPI file for the latest nc8430 BIOS? I didn't upgrade it for a while since I never found it.

- Everest? Do they have drivers for the nc8430?

Thanks for any clarification.
