Would like some information please

After reading the forums and so on about over clocking I decided to give it the go ahead, First attempt at over clocking. I had the 580 GPU over clocked

205 x 16. I set ther 580s back to stock and hit 214. Doesnt make since to me.

2 Loops Black Ice 360, Mother board N and S Bridge wet, Voltage regs wet.

None of my temps went over 32c

CPU wet

Multiplier 16

Base Clock 214 when I try 216 black screen only Is this a good base clock? CPU Volts 2.0 (not on auto)

Target CPU 3429 MHz

Target Memory 1286 MHz

CPU Uncore 3000MHz x 14

Memory Freq 800MHz 1.60v

Target memory 1286 MHzPCIE 100

I think at this point I could set my multiplier at 20 start at 185 Base Clock,

Should I set my memory volts at 1.60 at 1600MHz?

Set my CPU volts at 3.0 and increase the base clock untill I cannot boot., then start tweaking?

I have QPI at slow.

You have your CPU volts at 2.0!? You shouldn't be going above 1.5V at extreme clocks. You really don't need to push the bclk over 200. Use the multi from there to up your CPU clock. Volts should be around 1.3V for the CPU at 4GHz. This all depends on the silicon lottery though. Get your memory to 1600 with volts around 1.65V (if you have 1600MHz memory that requires 1.65v). QPI should not be on slow. QPI volts will need to be 1.3-1.35V and PLL should be 1.8-1.88.

Your gpu was probably sucking that much juice over clocked that your psu was unable to supply enough stable power for the CPU.

As blah said 2v is alot, I hope you did a typo there tbh or you might of knocked a year or two off your cpu life.

QPI shouldnt be on slow unless you are just looking for a cpuz screenshot either. Its not good for normal use.

On the 990x if you want it as a 24/7 usuable voltage I wouldnt go over 1.4v at the limit really.
