Is my overclock wrong?

Really could do with some clocking advice please, had to guess some of settings because Asus bios uses different naming conventions and different options as per guides and posts :(

- Intel Core i3 530 2.93GHz
- Asus P7H55-MUSB3 Intel H55 Motherboard
- Kingston 4GB (2x2GB) DDR3 1333MHz
- Samsung SpinPoint F3 1TB SATA-II
- Corsair CX 400W ATX Power Supply
- Microsoft Windows 7 Home Premium

Asus bios
BLCK 178 Mhz
CPU 1.275v
IMC 1.25v
DRAM 1.56v
iGPU 499.96 Mhz
iGPU 1.15v

CPU-Z
Core Speed 3916 Mhz
Multiplier x22
Bus Speed 179 Mhz

Under Memory says my DRAM Freq is 890 Mhz with CAS 9
However under SPD tab in timing table each colum is different frequency and CAS 6 7 8 9

Why can’t I touch or go beyond 4Ghz?
 
SPD is not what your memory speed actually is. SPD is a list of speeds that will be used by the bios when on auto settings.

Moving on to why you can not get above the 4GHz - one word. Volts.

Get your volts up a touch and you will get there. Vcore could go up and so could the vTT.

Look I am not 100% sure about that particular board that you are using, but most of the i3-530 CPU's will get you a BLK of 213 on nearly all the Gigabyte P55 and H55 chip sets motherboards I have built for mates.

I even got a Gigabyte Mini ITX board (H55N-USB3)to clock a i3-530 to a 250 + BLK overclock. Still have that CPU. :eek:

It was part of a contest held at HWBOT a few months ago and the point of the whole thing was to see how quickly you could run the 32 Mil version of Super Pi. So my final oveclock was 5.698 GHz :D

But that was not stable for a completed run of 32 Mil.

As to temps - I was getting 4GHz with ease of a stock Intel Cooler. So the CPU does not run hot as a rule. But for these frequencies you need to go sub-zero to clock. Dry Ice was used for this benchmark run.
