Dear listers,

Recently I got a black edition of Phenom 9600 with DFI's UT790FX-M2R. BIOS is Jan 3, beta.

I tested several operating systems on it. (1) Fedora C. 8 Install went on rather smoothly, but the login window seemed to be messy. A lot of non fatal errors. So, I stopped here. (2) FreeBDS 7.0/6.3 The installer could boot if acpi is disabled. I did not go any further. (3) OpenSUSE 10.2 No problem. But, the benchmark showed the half speed of the CPU. On the window executing top, the cpu load level of all 4 cores showed 50%. So, the recent kernel 2.6.18 does not know Phenom. (4) OpenSUSE 10.3 I had got a lot of trouble in installing this. In the middle of installation, the system hanged many times. It took more thatn half day to complete the installation of minimal graphical system. Enven after installation, I had to reset PC many times until the text login propmt comes out. Another trouble is it takes a very long time to shutdown the system. Once it starts, things go well without X.

Over clocking makes matter worse.

Well, DUH! Over-clocking is just asking for trouble. If the chip could run safely at a faster clock rate, the manufacturer would have detected the ability at the factory, and marked it with the higher clock. People are under the impression that the electronics components industry sets out to make capacitors or resistors of chips of precise ratings. Wrong. Chips of different speeds come off of the same line.. in fact, many times, off of the same wafer, even though every chip on that wafer is SUPPOSED to be identical. They make a design, and manufacture the design. Then they test them pile of components for whatever criteria (resistance, capacitance, clock speed, or whatever), and then sort them into groups, and label each group appropriately. If you want a faster CPU, go out and buy the chip that's been tested and certified at the speed you want to run at.

Troubles of Phenom with linux are reported somewhere in the net.

So, I plan to test opensuse 11.0 Alpha1, because it comes with newer kernel. But, it would be nice, if someone who tried it on 790(F)X sends quick report to the list.

Thank you for your attention. yoriaki fujimori

You are not alone. Many of us share your pain with the 10.3 installer. 10.2 install - no problems, 10.3 install - bloody mess, crashed gui installer, broken repair installation, etc. It will be interesting to see the kernel experts chime in and help us understand how the current kernel supports the quad core single die architecture and whether it does or doesn't have an affect on the 50% core load you are seeing. The problem could be as simple as a bug in the way the core load is calculated for quad core processors or as serious as something that prevents any utilization of the remainder of the processor power.
