Project "True 4x4"

[mreuter80]

I would say try that program mreuter80 linked to, since the registers SHOULD be the same, except there's the fact you're running 4physical cpus, so hopefully it knows how to address/configure all of them. I don't know the specific registers involved, but doing a registry dump might shed some light on the matter as well, but the winrar trick might be much easier.

Damn, I forgot this is the 4x4 thread I guess this program will only run for one CPU.
You also need to install Crsytal CPU ID before running the program (such a long time back when I installed it, that I forgot it now -- getting older ... who is Dave ).

Oooh, the benchmark numbers above are for a Phenom. I'm sure your Opteron system will show different numbers.

OK, with Crustal CPU ID comes the MSR editor where you can access the register settings directly (manually). Here is the link to the download page: http://crystalmark.info/download/ind...l#CrystalCPUID

Then apply the same steps for each "CORE" ... which is for your True 4x4 quite a bit

Select the Core in the main window.

Enter C0010015 in the MSR Number field and hit RDMSR.
Change the last hex digit. Bit Nr. 3 (8h) must be unset. If the last digit is 8h use 0h if it's 9h use 1h. Hit WRMSR to apply the changes.


Now enter C0011023 in the MSR Number field and hit RDMSR.
Change the last hex digit. Bit Nr. 1 (2h) must be unset. If the last digit is 2h change it to 0h. Hit WRMSR to apply the changes.


Close the MSR Editor, select the next core start the MSR editor and change the registers the same way as described above.

here is the link to our own xtremesystems guide with some nice pictures http://www.xtremesystems.org/forums/...d.php?t=171105

There was also a way to do this as a batch in this guide. So if it works you might want to look into it to have a batch running when you start the machine.

I hope that will help. Good luck man ... I keep my fingers crossed
