Spexx, could you please send me via PM a list of your different miners (link and which CPUs they work best with)? I'd like to make a list so new XMG miners don't have to read the whole thread. Probably joe want to add it to the OP. Gonna ask Marcus, too.
I have two miners available - the 64 bit and 32 bit versions for Windows. Both of them will run on any CPU and are subject only to the limitations of the operating system. The links for these are included on the OP.
32 bit
https://www.dropbox.com/s/dii8cvz7lp8xuey/XMGpoolminerWin32.rar?dl=0Works on every CPU I tried, down to Windows XP SP2.
64 bit
https://www.dropbox.com/s/hiadf8o5u7bsit7/XMGpoolminerWin64.rar?dl=0Windows 7 SP1 upwards.
Refer to this post if using the 64 bit miner
https://bt.irlbtc.com/view/735170.msg8926975#msg8926975I have an all-singing all-dancing program to do this for you. Release is imminent

Note that there will also be a newer version of the miner with this release, but it is only for the current live algorithm, not for the new algorithm running on the testnet which is only avaliable via the testnet wallet afaik. I have not seen a source code release for a standalone miner with the new algorithm yet.
