I bought the mobo, cpu, psu brand new and got raptors, sound card, ram from 2nd hand market. It took me 2 weeks to gather essential parts and built the system a month ago.
Very happy that the system could boot when it was first assembled naked (one 8800GTX,2G ram and my old Enermax 600W). When installing the windows, the system could not post after reset (a process in window setup). I suspect it was the mobo problem as I tried swap another 8800GTX, another 2G ram, another psu, it could not post as well. Took the mobo to the shop and tested, no problem. OK, it should be cpu problem then. However, the office hour of Intel agent is exactly the same as mine, such that I did not have time to go for RMA. I bought a 2nd hand E6300 as workaround next day after work. OK, plugged the cpu it and the mobo could post. So, I went to sleep.
I bought the rest of the part next day after work - a 1000W psu (it was out of stock before) and prepared for the SLI connection. Rush back home and connect everything. Power on the new psu... oh my god, it screamed better than my girlfriend. I checked everything alright except that rpm sensor did not give voltage. The psu was actually functioning, it just alerted me the fan (sensor) did not work! It screamed everytime the pc reset until I pressed that red button at the psu. Took the psu to the shop next day and exchanged a new one. The new psu worked fine at my rig and intended to continue the setup next day...
Next day, I was happy again..... until I install the forceware. After finished the installation, it required reboot, but could not post again. Swap everything again, should not be the problem of RAM, psu, video card card. This time it should be cpu or mobo problem? Borrow another E6420 from my friend next day and plug to my mobo, it could not boot. So mobo was dead this time.
Next day lunch time, I took the mobo to Asus service center, they tested the mobo and agreed to give me a new one. However, they did not have stock, and I have to wait for a week.
I got the new mobo a week later together with the rma E6420. Reconnect everything, the process seems smooth - it post'ed. Then I have time to complete the windows, drivers installation with few benchmark s/w. Tweaked the system about a week and finalize few settings. Another day I decided to put all the parts into the case, spent me about 2 hours (the case is small for 2 super long video cards). Connect the ac plug, it could not post... took out everything and power on again naked, no problem. Put them in the case again, no post. Took them out again, post! I don't know why.. should not be the case the the screw of cpu heatsink touch the case, this should not create the problem. Anyway, I sticked a tape underneath the mobo. This time it posted. I then ran the ortho 1 days to test the stability and observed the system temperature when they were in the case. Fine, idle at 34C and full load at 53C (room temp about 28C). Happy again...
Yesterday I tried to oc my 8800gtx pair. They could go up to 630/2000 without artifact. But I could only gain 200 in 3dmark06. I did not know why. I would investigate this later as it was quite late. Return all the settings to default. Before went to sleep, I checked email and surfed for few minutes. The system sudden hang! Could not post after reset! No time to check why as it was 4:00am.... time to bed (to be continued)
