CPU Temps

[BobS]

My A7N8XE Deluxe with an XP 3200+ using the stock AMD HSF had Motherboard
Monitor 5 showing the idle CPU temps in the mid to high 50's degrees C.
Although this is not super high, I was somewhat concerned. The airflow
through my case is good, and I used Arctic Silver 5 paste.

I came across a thread in one of the forums on www.pcper.com that uses some
(free) software tweaks. I tried this s/w in the past, but never had good
instructions how to set it up, and it never worked for me before, but it
sure works for me now that I set it up correctly. My idle temps now run
about 39 to 44 C, depending on the room temp. Running active applications
will bring the CPU temp back up to the mid fifties again within a minute or
so, and then reduce to idle temp when the CPU is running at lower activity.
I thought at first it was fooling MBM5's readings, so I rebooted and went
into BIOS, and saw that the hardware monitor was also reading much lower,
close to what was indicated in MBM. Staying in BIOS would raise the temp
again to the mid 50's, as it had been before applying this tweak. The tweak
only works while in Windows, but I am so pleased with it, I just thought
some of you would like to try it yourselves. There are 150 or so replies in
this thread, and not everybody had success, but most did. My message is
currently 2nd or 3rd from the last (newest).

Works great for me is all I can say.

Sort of stupid that the A7N8X officially supports "S2K Bus Disconnect"
but you can't enable it in the BIOS. ( IIRC there was an errata with
pre-Barton cores and bus disc so maybe Asus figured to just leave it
off?)

fwiw, I've been setting offset F6 to 1F for about a year now on my A7N8X
v2 with no side effects at all, well except for a cooler CPU/PSU/PC
room, less fan noise (thermal type), less dust in the case, etc,etc.,,

Hold yer horses - what's that setting your talking about? I've also got cpu
temp worries on my hands. Using the following setup, an idle cpu temp of
52°C is the lowest I have acheived so far.

- Silent Maxx Big Tower
- Silent Maxx Pwr. Supply 400W
- AMD 3200+ Barton
- Zalman Copper Cooler CNPS 7000 CU
- 1024mb Corsair XMS ram / dual channel
- gforce 4 TI 4200 128mb 8x
- Papst small case fan

Please, please... what must I do to keep it quiet and cool the cpu to below
50 in idle mode? I've been on this for 2 months now, and have no Ideas left.

Thanx, Andy

Well, I just use WPCREDIT.EXE and this (http://tinyurl.com/3bn35) to
change offset 6F to 1F, or a program like SpeedFan that has the option
built in and can enable it for you when they start.

btw, the zip file in the URL above also includes a nF2 PCR file for
WPCREDIT.

Ooops. Thanx for the reply - problem is, I dont really know what this offset
thing is.

Look at that picture in the thread,
http://rh03.hostreflex.com/~pacman10/Drisler/wpcredit.jpg

See offset 6F? , it's normally 0F or 9F on most nF2 boards by default,
when set to 1F it enables S2K bus disconnect!

First you need to download WPCREDIT (google it), unzip to a new folder
and run WPCREDIT.EXE, then just move the cursor over to offset 6F and
then edit it so the data is 1F instead of 0F or something else. I've
been using my SetF6.exe (in the zip) for so long I forget how to edit
it, but i'm sure it's easy to figure out.

btw, IIRC there is also the WPCWRITE.EXE that can set all of your
settings at boot up, I've never bothered with it myself. ;p

Thanx for the links provided. I'm still sorry to say I dont know what this
offset setting is or does, changes or affects. Never heard of this b4. Will
this help sink the temp on the cpu?

Yes.

The S2K bus disconnect – a way of reducing power consumption, is pretty
interesting. This feature needs BIOS support from makers of Barton
motherboards. But AMD is telling its system integrators that validated
S2K Disconnect mobos will work when used with earlier XP and Duron
cores.

There's some background to S2K Disconnect. The feature has been present
in Athlon chipsets and CPUs right from the start - the idea being that
when the OS becomes idle, the microprocessor disconnects from the
chipset and goes into a low power mode.

But it's been kept disabled in the past as Spitfire Durons and
Thunderbird Athlons sometimes would not reconnect - errata numbered 11
and 14. But AMD is asking mobo makers to enable the feature because,
presumably, Barton doesn't have that nasty habit.

Cheers,
Ed

btw, AFAIK offset 6F is just for the Nforce 2 chipset boards, VIA/SiS no
doubt have a different location for this setting (if they support it).

For my older AMD/VIA chipset systems I use a program called VCool, they
call it "Enable Cool Bit" or something like that.

I've been using some sort of cool bit tweak since my first AMD socket-A
(late 1999) and never had a problem with it enabled.

Good luck,
Ed

Andy, did you try my original link I posted? Everything you need to do and
know how to set it up is right there at the beginning of the thread.
