I tried to follow the following links but my pc doesnt even boot past the bios screen and keeps crashing on its own then i have to reset to default values to make it run again
I have two different ddr3 rams 1xgskill ripjaw 4gb & 1 x samsung 2gb could this be a issue.

other details

Kindly help me need this pc to work urgently..
thanks in advance

UPDATE :
these are settings screenshot from the above youtube link that i followed although the motherboards used in the video is slightly upgraded P55M-UD2, but i tried these settings ,still failed

That's not really an overclocking set up, so it would be even more difficult for a beginner.

You need to increase BCLK, but at the same time adjust your CPU Ratio, DRAM Ratio, CPU VCore, DRAM Voltage, and that's just to start.

With default settings as is right now, is the system stable with the two types of RAM installed?

yes it is working well on windows 8.1 with radeon 6850 ,btw i tried the following for overclocking and failed many times

Base Clock of 205MHz
multiplier set to 20x
V Core 1.35V
VTT to 1.37V
pch core 1.14V
PLL 1.9V
kept dram to default

where am i going wrong?? btw I am always ready to learn !

Did anything in between that work? You should scale up so you know what works, what's needed, so forth. BCLK 133 to 205 is major leap. The CPU may not even be capable of 205.

I followed this link for the above values which is the review of the motherboard along with overclocking method in the last paragraph

please check it for me, because i want it to reach 4ghz over air, kindly help me out

RAM settings should be default. Your memory timings are not 7-7-7-24, so the system will not work if you set it like that.

QPI/VTT does not need to be 1.37V

Set all those back to default or AUTO and try again.

You need to leave DRAM to AUTO and adjust CPU values ONLY. Those pictures show many changes for DRAM that do not apply to your computer. Most likely why you have 0 luck.

Just tried as u said but still no luck , this is all that i changed

Base Clock of 200MHz
multiplier set to 20x
SPD to auto
V Core 1.35V
VTT / QPI to auto
pch core 1.14V
PLL 1.9V
disabled :- smart fan control , intel turbo tech , CIE , EIST func , thermal monitor , c3-c6-c7 state ,

Try a lower value first, you can not expect to jump 2.67GHz => 4.0GHz in one try.

PCH Core and PLL can be AUTO for now.

Post some pictures of your BIOS

Here are the pics of my pc bios with default settings btw i think the samsung 2gb is not being detected by the bios but it shows in cpu z .

Only have the G.Skill RAM installed, Samsung can not be used together.
CPU Clock Ratio - 18
Set Base Clock Control (BCLK) - Enabled
BCLK - 200
System Memory Multiplier - 6.66

Test that, then you can raise CPU Ratio and CPU VCore to reach 4.0GHz

Just tried the setting as per your advise but still no luck....Btw i tried once by increasing the BCLK from 133mhz to 140mhz and achieved 2.8ghz without pc crashing with CPU clock ratio 20x

 

[gskill support]

You may want to try CPU Ratio 16X, and first see the highest CPU BCLK you can boot.

 

[Hargobind Shan]

uptill now
with ratio 16x i could only reach bclk of 160mhz
with ratio 20x i could only reach bclk of 155mhz
But i noticed after the pc crashes on higher settings , it doessnt boot past the bios screen until i switch off my pc for 10-15min and retry to enter bios and reset the values.

Sorry, I forgot to mention you need to set System Memory Multiplier to 6X while doing the previous tests. As you increase CPU BCLK, it overclocks multiple frequencies so you need to make sure values are within what your hardware is capable of.

For any power saving options, you should disable them.

CPU BCLK = 160 mhz , kept System Memory Multiplier to 6X and disabled :- smart fan control , intel turbo tech , CIE , EIST func , thermal monitor , c3-c6-c7 state ,

So the pc booted up at 160mhz then after a restart it crashed btw my bois power management screenshot is there anything to disable?

Are you getting blue screens of death, reboots, or? The problem sounds very strange right now, a piece of hardware may not be working properly. Is the system fully stable with all AUTO default settings?
