i5 750 Settings?

[Westyfield2]

'evening folks.

I've just been having a first attempt at Overclocking an Intel Core i5 750, it had been running on stock clocks with the stock cooler until today which I've now replaced with a proper cooler. I'm wondering if anyone would care to share their settings?

Memory I've got is 2x2GB of Corsair XMS3 1600MHz 12800C9 and the Motherboard is an Asus P7P55D.

Right now I've put it on CPU Ratio Setting 21.0 and BCLK Frequency 205, giving a speed of 4.33GHz. DRAM frequency I've put on DDR3-1640.

All voltages I've left on Auto apart from DRAM which I've put up to 1.65V.


I'm just using it for a bit now before giving it a bash on IntelBurnTest and Prime95. Not sure how much further I want to push it really given that I'm on air cooling and the RAM hasn't got any heat spreaders....

Just to update this...

Wasn't stable at that . What I've now been running for a few days and is fine on the IntelBurnTest is:

CPU Ratio Setting: 21.0
BCLK Frequency: 200
PCIE Frequency: 100
DRAM Frequency 1600MHz
QPI Frequency: 6407MHz

CPU (Fixed) Voltage: 1.45000
IMC Voltage: 1.43125
DRAM Voltage: 1.7125
CPU PLL Voltage: 1.90
PCH Voltage: 1.15

Memory speeds are as per the manufacturers specs.


Anyone been above 4.2GHz stable on air with an i5 750? Right now I'm seeing how much I can lower the CPU voltage by (but keep stability) as 1.45V is a little bit high for my liking.
