Q9000 running effect on T61

I believe that the news of the successful installation of the 4-core on the T61 has fulfilled the dreams of many engine oils, but after having eaten the crab, I am not as happy with the 4-core on the T61 as it is now when the 1066 FSB CPU is installed. Since T61 and quad-core are not the original equipment, the compatibility of the first-generation C2Q quad-core is also known to be "lack of safety." Let's enumerate the precautions for the 4-core on the T61

1. CPU thickness

On the right is QX9300, on the left is P8400, the substrate of QX9300 is thicker than P8400

What will be the result of this little extra thickness?

Since the quad-core CPU is definitely thicker, the four corners of the heat sink of the device will bend downward more, as shown by the red circle in the picture.

So please only screw it when you install the radiator, don’t press it down too hard.

2. Liquid metal

Be careful not to leave leisure between the radiator and the CPU, otherwise the liquid metal will oxidize for a long time, and the mercury will volatilize and clean, and it will become like a nose candy on the ground.

3. Heat dissipation

If you want to use quad-core, changing the radiator is basically inevitable

And what is even more cheating is: C2Q quad-core does not support SLFM

In other words, the lowest frequency is 1.6Ghz, the standby temperature is 5-10 degrees higher than the T9 series, and the full load temperature. ... ..

Known bugs:

1. Let me talk about the most serious one first:

QX9300, two centers operate at 2.5Ghz, two centers operate at 1.6Ghz

Q9100, two centers 2.26Ghz, two centers 1.6Ghz

Q9000 is similar

as the picture shows

The reason is still being explored, el-sahef estimates that it is DSDT

Temporary solution: Throttlestop can be used to force the other two centers to promote multiplier

2. Fixed screen crash/Unable to boot/Unable to wake up/Unknown reason to restart

Cumulative number of presentations for 3 days of trial:

Under Windows XP

Fixed screen crash: every time you turn on the power manager to change the power mode, you will die, do not turn on the power mgr to fix the screen for 5 times

Unable to boot: 1 time,

Unable to wake up: 3 times,

Unable to shut down: 4 times,

Unknown should restart: Did not pay attention

Under Windows 7

Restart for unknown reasons: 1 time. Estimated to be caused by overheating

Quad-core compatibility with windows XP does not seem to be very good

The reason for these results may be that the enameled wire I used is too thin, because el-sahef has said that the connection between GTLREF and GTLREF_2 should be as short as possible.

Conclusion

This is the end of the related introduction about the effect of Q9000 on T61. Please correct me if there are any deficiencies.

Welding Diode

Welding diodes are available for medium frequency (over 2KHz) and high frequency (over 10khz) applications.They have very low on - state voltage and thermal resistance. Welding diodes are designed for medium and high frequency welding equipment and optimized for high current rectifiers. The on-state voltage is very low and the output current is high.
