HP DC7700 CPU upgrade

Help with an HP CPU Microcode update.

I have a couple of HP/Compaq DC7700 PCs. They came with Pentium 3.0 ghz dual core cpus. HP has a microcode update to allow C2D cpus to function. So, I bought two Core 2 duo e7600 cpus. Before the microcode updates, the PCs beeped and complained. Also the fans reved up and went full to full speed. So, I applied the microcode update and no more beep or runaway fam issue. But those were replaced with two NEW issues.

1. The e7600 is a 3.06 ghz chip and it is only running at 1600mhz. The multiplier is stuck at 6x. Seems like SpeedStep is broken. Full speed is 11.5x. The e7600 chips have a CPU id of 1067A. Seems with this particular CPU id is messed up in the microcode. There are many HP forum discussion on this.

2. When the PC goes into sleep mode, is wont/can't wake. Nothing but a hard shutdown 10 sec power button can get it out of sleep.

As stated before these two issue are widely reported and HP has turned a blind eye to it. BTW, other CPUs (not 1067A) do not seem to have the issue. At least none reported.

So, I turn you you fine poeple in search of a resolution to this perplexing microcode problem. Any ideas? I hope that without all that other BIOS stuff to deal with, this would be an easy fix?

Here is the large link to the microcode update file.

File name is sp51243.exe
I extracted and used the DOS boot method. The raw file is exposed using this method.

Thanks!
