Dual Core Processors

Topic T1161 Applies to All NEO Products


Problem


NEO synchronization stalls.

If you have dual core processors on your machine, there may be a benign threading issue here.

We have seen NEO stall during syncing with such processors, although this is a rare event on such machines. We do not know why it happens on one dual processor machine but not on another.


Resolution


If you have an AMD dual core processor, can you please apply the following patch which is produced by AMD to get over this issue. You can find it here -

http://www.amd.com/us-en/Processors/TechnicalResources/0,,30_182_871_13118,00.html

It is the download option labelled -

AMD Athlon 64 X2 Dual Core Processor Driver for Windows XP and Windows Server 2003 Version (exe) 1.2.2

You should be downloading and running an executable named amdcpu.exe.

Workaround

If the above solution doesn't work, you may need to apply an affinity mask to NEOPro.exe and W32MKDE.EXE.


The issue with this workaround is that it needs to be applied whenever NEO is opened. Our experience is that the AMD fix works for AMD Dual core processors and so the workaround will probably not be necessary.
