Cool N Quite again (VNF3-250 + Newcastle)

[Ed]

Awhile back I posted that Cool n Quite didn't work on my Chaintech
VNF3-250 with a Newcastle 3200+.

A post on /forums.pcper.com/ suggested it works but only using one stick
of ram, hmmmmm interesting, never tried one stick in this system....

With CnQ enabled....
2 or more sticks of ram - System Locks Up!
1 stick of ram - System OK!

hth,
Ed

i have one of them also with 2 sticks of ram, cool and quite works fine
most of the time but i have locked it a few times running gentoo linux and
some scripts knock it into different throttling states, i always figured
that it was more likely to be a gentoo prob, if you remeber it wasnt
originally supporting C&Q and implimentied it with a bios update so its
not like we can complain to much.

Which drivers are you using? There was a major update of drivers in July:

On my nf3 ultra the voltage changing part only works if voltage is set to
auto in the bios.

You could try CrystalCPUID instead. To modulate the voltage the bios must be
set to auto or default for the cpu voltage. You can set custom speeds and
voltages, so be sure to hard-test each with p95.

It's neat to see the icon in the tray tell you the current speed. Plus you
can right-click and lock it to fast, medium, or slow.

I uninstalled all the AMD cnq stuff. I think it's best to do that before
using Crystal.

BTW My CrystalCPUID settings. I set it to stay in low speed as long as
possible, until 80% cpu usuage. This seems to impact benchmarks that don't
peg themselves at 100% just a little bit.

cpu is 3200+ Winchester, 10x max, and I think it's 1.4v stock. It boots at
voltage=auto, 8x because the clock is at 240 and I don't want it to goof up
overclocked while booting with a stock voltage.

Max 10x 1.45v hold for 1 sec. down at 60% cpu usage
Mid 7x 1.4v hold for .1 sec. up 80% down 30%
Min 5x 1.2v hold for .1 sec. up 80%

enable voltage
exit mode maximum
wait time 0ms
up min > mid > max
down max > mid > min

Oh, I forgot to mention that with CrystalCPUID and my nf3 ultra Gigabyte
K8NS-939, though the voltage selections go higher, it will only allow me to
select up to 1.45v, so if I want the voltage to go down on the fly, that
limits my overclocking. I could set the voltage higher in the bios and let
it stay there. But I get a nice 20% overclock at 1.45 and love running at a
low voltage most of the time.

Thanks, but I believe only the Newcastle cores are effected, others who
have same board with clawhammers don't have the problem either.

I've tried them all (system is 1 year old ,) it's not the driver it's
the board, seems users with clawhammers and newer cores don't have the
problem.

That'd be odd - the Clawhammer is an older core than the Newcastle. I
guess it could be that your BIOS does not support the Newcastle fully
though I've no idea on details of how. I have a Newcastle on a nForce3 MSI
mbrd and the CnQ works OK on it.

I don't doubt that I've built a few systems using MSI for friends and
they've worked out very well. Well just a heads up to anyone with a
VNF3-250 and an "AX" Newcastle, 2 or more sticks of ram break CnQ.

Could be a bug in the CPU itself?
http://www.amd.com/us-en/assets/content_type/white_papers_and_tech_docs/25759.pdf

Errata 79 sounds like a good candidate...

79 Power Management Limitations Above 1.50V

Description
Processor versions with a core voltage greater than 1.50V do not
support Northbridge low power mode while in the S1 power state or
LDTSTOP_L initiated HyperTransport link width/frequency changes.

Potential Effect on System
Unpredictable system failures may occur.

If voltage was the problem then it would lock up with one stick of ram
also. Again... 1 stick of ram CnQ works perfect, 2 or more sticks of ram
and Windows won't even load (with CnQ enabled).

Newcastle 3200+ CnQ Min/Max reading w/1 stick of ram. ;p
1GHz @ 1.10V
2.2GHz @ 1.50V
