This motherboard, case, and power supply are the core of my desktop machine and the machines I build for clients. The 2.4C processor and 256 MB of RAM represent skimping to get the price down to near $400.00. Honestly, if you're going to build a new hyperthreading box for yourself, spend the money to do it right. You're a developer and power user; time is money. $600 vs. $400 now will save you countless hours over the next several years. I have a Pentium 4 2.8E GHz processor; current is 3.0E. I recommend it for power users and SOHO servers (+$32.00): http://www.newegg.com/app/viewProductDesc.asp?description=19-116-171&DEPA=0 I have and recommend 1 GB of matched pair DDR 400 for 800 MHz FSB Pentium 4 systems (+$94.00): http://www.newegg.com/app/ViewProductDesc.asp?description=20-141-423&depa=0 Here's the hard drive I use in all systems ($59.79): http://www.newegg.com/app/ViewProductDesc.asp?description=22-144-122&depa=0 Here's the script running on my machine: dpchrist AT p42800e:~/mydocuments/cygwin-issues/hyperthreading$ cat test #! /bin/ksh mypath=$(pwd) while [[ ! -z $mypath ]] do mypath=$(pwd) if [[ -z $mypath ]] then echo "Test Failed......Path is empty" fi done When I fire it up in two Cygwin Bash windows, one or the other fails within 3 to 10 seconds: Trial #1: dpchrist AT p42800e:~/mydocuments/cygwin-issues/hyperthreading$ ./test Test Failed......Path is empty Trial #2: <CVSENV>dpchrist AT p42800e:~/mydocuments/cygwin-issues/hyperthreading$ time ./test 4 [exiting thread] pdksh 3684 cygthread::stub: erroneous thread activation (shell locked) Trial #3: dpchrist AT p42800e:~/mydocuments/cygwin-issues/hyperthreading$ time ./test 4 [exiting thread] pdksh 2532 cygthread::stub: erroneous thread activation (shell locked) Trial #4: dpchrist AT p42800e:~/mydocuments/cygwin-issues/hyperthreading$ time ./test Test Failed......Path is empty real 0m41.530s user 0m55.135s sys 0m21.650s David -- Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple Problem reports: http://cygwin.com/problems.html Documentation: http://cygwin.com/docs.html FAQ: http://cygwin.com/faq/
