Is OCing this Possible?

I have Pentium(R) Dual-Core CPU E5300 @ 2.60 GHz, and looking at OCCT it says

"CPU Frequency: Current - 1200 | Original - 2600 | Overclock - -%53.8"

Urm, I'm pretty sure that's horrible if I'm getting half the speed I should be, is it possible to overclock my PC?
 
It's called Speedstep. The processor clocks down to a lower speed and turns unused cores off to save power. It automatically clocks back to 2.6GHz when it is under load.
 
It's probably Intel SpeedStep which reduces the speed of the processor when idle to save power.

Download CPU-Z and have it open while you run something like Prime95 to stress the CPU.

Hopefully you should see the processor speed jump up.
 
I suggest you get it working at 2.6GHz first.

2.6GHz is achieved with a multiplier of 13 x a Base Clock of 200MHz.

Your idle speed of 1200MHz suggest 6x200MHz which is correct.

Your load speed of 1700MHz suggests 8.5x200MHz instead of 13x200MHz.

You need to look in the BIOS for the CPU multiplier and see if this has been set to 8.5 or auto. It should be on auto.

I have made E5300 and E5400 builds on cheap G41 motherboards. All I did to over clock them was increase base clock to 266MHz and increase Vcore till they were prime stable.

E5300 - 13x 266 = 3458
E5400 - 13.5x 266 = 3591, this one was prime stable but not IBT stable, so I dropped it to 13.5 x 250 = 3375.
 
Hell yeah, got it fixed! My PC is so much faster now, I can't believe I was gaming at that speed all this time.

It seemed my BIOS was for some reason modified, and was at 8x and not 13x, so I restored defaults and it automatically changed to 13x. :)

So thats that sorted. Now should I OC it to more than 13x?
 
You can't increase the multiplier past 13x - the CPU will just ignore it. If you want to try overclocking you will need to increase the FSB as detailed above.
 
Alright I just changed it to 2.86 GHz.

I'm testing the temperature whilst stressing it for 30 minutes to check stability, I will post results here.

P.S: In BIOS I have an option where it says "Something Mode: [Turbo]" In description it details that if I OCed and want it stable, I should set it to "Standard" There's also an "Extreme" option. Should I do this?

I'm looking to go for 3GHz.

Also, what are normal temperatures of 2 fans whilst being stressed @ 2.86GHz?

And above theres mention of "Increase vcore until they were prime stable" < -- What is this?

Edit: I just OC'd to 3.00Ghz, I tried making the vcore but I got fail boots, so I left it at Auto.

It seems to be 1.2V ~ at 3GHz

I changed the Enhance to "Standard" for more stability. I seem to be getting similiar but lower temperatures from 2.86ghz at 3.0ghz (Most likely because I removed the "Turbo" enhance mode)

Edit2: I'm playing a game right now, seems all smooth. It's very nice actually not lagging for once :)

Avg Temperatures whilst gaming are around 50, Max 60. :)
