Hi, I installed a second CPU on my Compaq ML370 G2, and it is *slower* with 2 CPUs than it was with 1. The machine acts mainly as a file server. It was that bad, that I had to disconnect the 2nd CPU (ie, switch back to ACPI Uniprocessor PC on the device manager). NOTE: I have tried setting the affinity of some processes (using the NCR SMP Utilization Manager tool and the standard Windows PerfMon) as well as the affinity of the NIC cards by changing the registry entry. No luck. And I'd rather not have to spend the next 6 months fine-tuning this. MY QUESTION: Is there a device manager that supports ASYMMETRIC Multiprocessing on W2K Server? All I need to do is run SQL Server and bind it to CPU #2, while letting CPU #1 run *everything* else. Or: does anyone want to buy a brand new PIII 1.4GHz CPU from me? In the box, $350... :-) (Please cc: me in your answers if possible, yiannis@cs.neu.edu)

could possibly be a problem with the L2 cache on the new cpu i have seen that problem on a single cpu system although you have 2 cpu's, one faulty cpu would severely bottleneck the working one.

Thanks Danny! So how do I find out if the L2 cache on the 2nd CPU is faulty? I'd rather avoid any messing up with the hardware, that CPU was not easy to plug in to begin with.

I can't think of any other way apart from trying it in another machine, unfortunately. :) someone else may have a suggestion though??

FYI, I did find a tool to troubleshoot the L2 cache. Check out cachechk in this page: http://www.bookcase.com/library/software/msdos.util.sysinfo.html I have a niggling suspicion though it's something else...

You may have to re-install Win2000server. This is because the install for single CPU differs from that of Dual CPU

Peter, you mean that the device driver change from Uniprocessor to Multiprocessor is not sufficient? There is absolutely no way I will undertake a reinstallation of the OS. I'd rather take out and burn the CPU in the middle of the office in style. (you are free to quote me on that to your friendly Microsoft representative :-)) So is there no way to turn a W2K server to an asymmetric setting, as opposed to symmetric? Can't bloody microsoft for once stop "upgrading" stuff to become worse? (from asymmetric in NT 3.5 to SMP in 4.0). Bloody hell. Anyway, thanks Peter, not your fault and not your ($80 billion, by the way) paycheck. Yiannis
