3570k Overclock - Which One For Daily Setting?

[JimboTheGiant]

I've been having a play with overclocking my 3570k. My results are shown below:

-0.070v (LLC Level 1 = 1.170v Load) = 4.4ghz - Prime95 Blend Stable (10 Min Run) / IBT Standard Test Stable (Max Temps: 57/63/61/61) Avg: 110 GFlops
-0.060v (LLC Level 1 = 1.180v Load) = 4.4ghz - Prime95 Blend Stable (10 Min Run) / IBT Standard Test Stable (Max Temps: 58/63/62/62) Avg: 110 GFlops
-0.050v (LLC Level 1 = 1.190v Load) = 4.4ghz - Prime95 Blend Stable (10 Min Run) / IBT Standard Test Stable (Max Temps: 58/65/62/62) Avg: 110 GFlops
-0.035v (LLC Level 1 = 1.205v Load) = 4.5ghz - Prime95 Blend Stable (10 Min Run) / IBT Standard Test Stable (Max Temps: 0/0/0/0) Avg: 112 GFlops
-0.025v (LLC Level 1 = 1.215v Load) = 4.5ghz - Prime95 Blend Stable (10 Min Run) / IBT Standard Test Stable (Max Temps: 63/71/67/65) AVG: 112 GFlops
+0.005v (LLC Level 1 = 1.245v Load) = 4.6ghz - Prime95 Blend Stable (20 Min Run) / IBT Standard Test Stable (Max Temps: 67/75/70/69) Avg: 114 GFlops
+0.010v (LLC Level 1 = 1.250v Load) = 4.6ghz - Prime95 Blend Stable (20 Min Run) / IBT Standard Test Stable (Max Temps: 66/73/69/69) Avg: 114 GFlops
+0.020v (LLC Level 1 = 1.260v Load) = 4.6ghz - Prime95 Blend Stable (20 Min Run) / IBT Standard Test Stable (Max Temps: 67/75/71/68) Avg: 114 GFlops
+0.040v (LLC Level 1 = 1.280v Load) = 4.6ghz - Prime95 Blend Stable (20 Min Run) / IBT Standard Test Stable (Max Temps: 69/78/74/73) Avg: 114 GFlops
+0.060v (LLC Level 1 = 1.300v Load) = 4.7ghz - Prime95 Blend Stable (20 Min Run) / IBT Standard Test Stable (Max Temps: 72/83/76/74) Avg: 116 GFlops
+0.080v (LLC Level 1 = 1.320v Load) = 4.8ghz - Prime95 Blend Stable (20 Min Run) / IBT Standard Test Stable (Max Temps: 76/86/79/78) Avg: 118 GFlops
+0.130v (LLC Level 1 = 1.360v) = 4.9ghz - Prime95 Blend Stable (10 Min Run) / IBT Stable (Max Temp 85c)

Whilst I know that these are only short term stability tests, I can shoot for a longer term test later on.

Just really want to get your opinions on which speed you would shoot for, to use on a daily basis.

My BIOS settings are below. If you know of anything I can change that will allow me push for a lower voltage at the same speed, then i'd be happy to know

What board and cooler you using out of interest?

 

[JimboTheGiant]

I'm under custom watercooling using an EK 240 kit on an AsRock Z77E-ITX in a BitFenix Prodigy

Agreed.

I would say 4.8 as non linear relationship between vcore and speed takes a jump after this so you are nearing the limit on that cooling.

IBT kills memory controllers by the way. Use your PC to test for stability not that trash.

Gonna say some really good temps.


Think spixel has it about right.

I use Prime95 to test, IBT seemed harsh. Got to get me 1 of these. What's the max temps for these on air?
