for what i know on dual core 1000 isn't suited cause it makes the system
unstable.... the suggested is 100 or max 250 if you want a low latency
desktop.... also, the 1000 on single core 64bit is very unsable and the
processore state has a very great shift around.... i experimented that
single core amd64 should have the best timer freq or 250 for a normal
desktop and a dual core amd64 should have 100.... but anyone is free to try
and use other freqs as they like most....
