Owners of X9100 (E0), P9600/T9600/T9800... help

I have a QS X9100 C0 stepping which is VID-locked to 1.0V

And, I want to replace it with a different part with lower minimum voltage, as it influences my idle temperature (and keeps the fan running)

Did anyone here buy QS samples (or retail) of:

- X9100 E0 stepping
- P9600
- T9600
- T9800

If yes, please post your minimum voltage at idle (and your CPU info - e.g. model and stepping) - this is usually the lowest voltage the CPU allows.

There are many ways to see this voltage - e.g. by checking it in RMClock, CPUgenie or in some diagnostic software - e.g Everest...

Thanks!

Use this tool to get the actual infos about your system. Some monitoring tools goes crazy sometimes.

 

QS T9800 E0

Minimal voltage: .095v

 

I have T9600 (@ 2.8 GHz), but I'm at school now... My notebook is at home

 

My T9600 @ E6500 (DELL).

Revision/Stepping : 17 / 6 (0)
Stepping Maske : C0/M0
Microcode : MU0617060C

Vmin= 0,950 (checked with VIDunlock of CPUGenie and RmClock)

Maybe a simple change of the thermal compound can help you.
IMHO "Coollaborytory Liquid pro" is the best one and I used it in different notebooks.
It gave me a reduction of about 9 degrees Celsius to 35 degrees idle@800MHz&0,95Volt without fan.
And it gave me a 19 degrees reduction at full load.

What is yout idle temperature now?

 

I used Artic Silver 5 and spend some quality time making the thermals better - but it is quite limited what you can do with Sony Vaio Z's 25W heatsink - it is just not designed for this kind of CPU....

But after some hard work - I am gettin ~49C idle and it can run @2.8 GHz @100% without throttling at all. 2.8 GHz is prime-stable @1.025V here.

At 2.93 GHz I manage to run it @100% stress for approx. 1 min 30 sec without throttling... 2.93 GHz runs at 1.062V stable..

3 GHz is useless on this machine - Requires 1.125V for my C0 X9100 and it is just too hot.

I think this is as low as you can go with X9100 C0 on this laptop - the heatsink is just to small...

 

New T9800 CPU running running in my old Dell E6500 now.

800 MHz 0,950V=stable 0,950V=productive (minimal Vcore)
idle@38 degs Celsius

2933 MHz 1,062V=stable 1,075V=productive 1,050V=Failure
Superpi 2M: 39,343sec @50 degs Celsius with CLP thermal paste
Idle@38 degs, 100% load@72 degs

 

Good details regarding the X9100 (E0), P9600/T9600/T9800... I never knew they had that much difference when diagnosed with stress test.
