The 47 Ronin
CPU: Intel C2D E8400 Rev. E0
MOBO: Maximus Formula X38
RAM: F2-8500CL5-2GBPK (4x2GB)

CPU volt - 1.275v
NB - 1.30v
DRAM - 2.1v

I researched some old threads on this combo and arrived at the above settings. I've always had this running stock for the past several years, but today I wanted to live on the edge just for a little while. SOOOOOOOO anyways, Rated FSB at stock was only 1066 MHz, but now it's 1599.91 MHz. Is this okay or tomorrow it die? ^^

What kills them is heat.

Prime95 will show you what your system can handle as it puts a massive load on it that you will never see in daily use. Run Prime95 for an afternoon, if it survives that it should be good to go.

Have the person check the power connector is seated cleanly in the power supply. Also, try a different outlet for the power cord, direct to outlet and not through a power strip.

I have a small check list:
1. PSU switched on. check!
2. PSU cable plugged in firmly. check!
3. PSU cable plugged directly into outlet. check!
4. re-seat GPU. check!
5. re-seat motherboard power 20+4 pin. next
6. re-seat memory. next
7. re-seat cpu power 4+4 pin. next
8. clear CMOS? :(

The heatsink covers half the motherboard so re-seating memory & cpu 4+4 pin is going to be tricky.

Motherboard LEDs light up when the PSU is plugged into the outlet, but when the power button is pressed, all fans spin for a split second and then nothing...
