Multiplyer [48]
CPU VCore [1.44V]
Internal PLL Overvoltage [Enabled]
Memory frequency [1600MHz]
DRAM Voltage [Auto (=1.65)]
VCCIO [Auto (=1.05V)]
CPU PLL [Auto (=1.8V)]
Enhanced Intel Speedstep Technology [Enabled]
VCore PWM mode [Extreme]
VCore LLC [75%]
VRM Fixed Frequency Mode [350kHz]
VCore Phase Control [Extreme]
Hyper-threading [Enabled]
C1E [Enabled]
C3 [Auto]
C6 [Auto]

Hi guys, I am quite stable now on 4.8GHz with 1.4 Vcore and would like to push to and may be above 5GHz
However I need some help,when on 5GHz cant boot into windows, BSOD 124 error

Multiplyer [48]
CPU VCore [1.4V]

Internal PLL Overvoltage [Enabled]
Memory frequency [2133MHz]

How's your temps going? I would think bumping up the Vcore a tad might help but I wouldn't if your temps are too high.

~75'C
how much increase do you suggest?

At 75c, you are approaching your ceiling anyway. I would leave it alone honestly. Once you get into the 80c range you're gonna have to watch it really closely and your chip can really start to degrade quickly at that point. If you're stable at 4.8 using 1.4v, your chip will likely make it to 5.0 with better cooling. What cooler do you have ? You should really fill out your rig specs in your profile so we can better help you.

The answer is Vcore. You'll need to bump it up to get to 5 - I wouldn't be surprised if you need 1.45V or even 1.5V to get there. Be sure to watch your temps at those voltages though.

I will try 5GHz and see how the temp goes. I;m using antec 920 for cpu cooling

Couldn't get to 5GHz still
ran again Prime 95 on 4.8GHz but some problems occured BSOD101
any suggestion?

Most 2600ks I've seen need around 1.46-1.5 to hit 5.0. Mine needs 1.48. If your cooling can't support higher voltage, just leave it, as it probably needs more.

I know it typically doesn't hurt on sandy bridges, but my old socket 1156 Lynnfield CPU would get an extra 200MHz by turning HT off.

I put my 2600K at 1.35 volts and 4.7GHz was the fastest I could get and get it able to pass a four hour stress test...I never did try to turn HT off though. Perhaps once you hit these higher speeds turning it off might help.

Also, are you sure your memory (and the CPU's memory controller) is good to go at 2133MHz? You could try turning that down a bit. It wouldn't even hurt your performance.
