Here are just a few ( dozens more have been given to you by me and a host of others) suggestions you have been given about your system crashes. Really, I don't what more is to be said:
The first thing you need to know is that the Maximus Formula Overvolts Ram.
You need to set the Dram Voltage to 2.04v within BIOS to get 2.10v.
Also set the NB voltage to 1.44v
Also make sure you are using the latest BIOS 0907, it has more Ram Compatability built in it.
Make sure your Command Rate is set at 2T, and NOT 1T.
Make sure you are using slots A1 & B1.
Then try A2 & B2.
You can also try setting the Ram timings to 5-5-5-15 at 1.90v and see if it will work at a higher latency
Then you had then following advice given to you:
its most likely an issue of incompatibility and you might have no choice but to change your ram or board. try Kensek's tips and if they still not helping just replace your ram with another type or brand. ncix seems to be pricey too so i feel your pain. let us know how it goes. good luck
Then:
first off, always go to the manufacturers website to check ram compatibilty, i have this board and bought it from www.newegg.com and read reviews on the board and too many people were having problems with the corsair ram, that is my ram of choice(xms), so i bought crucial ballistix, it works great.....
next, all these people who go into their bios and overclock are wasting their time, i have overclocked my q6600 to 3.61mhz using the asus gear 3, u can adjust the volts and timing of the ram there as well, also make sure u get an aftermarket cooler if u have an e or q model intel cpu, the stock ones suck, download cpu-z and core temp programs to monitor ur hardware
Maverick. The symptoms all point to your RAM. I have answered you on numerous posts regarding your system.
