E6550 overclocking issue

Hi Guys.

Recently ive been trying to overclock my system. im still quite fresh to overclocking and i came across a little issue during the process:

First i started off with ram.

originaly my ram is 400 mhz at 800 FSB wich had taken 1.8V
I ran it at 1100FSB and lifted the voltage to 1.9V and everything was running fine.
Then i lifted it another small bit to 1200FSB at the same voltage the bios screen wouldnt start and event though i lifted the voltage to 1.95V it wouldnt start so i put the settings down to the original and went ahead trying to overclock the cpu..

The CPU is original @2.33 Ghz.. thats multiplier x7 and fsb of 1333 at 1.248V-1.32
So i played around for a little bit and could only overclock the cpu to 1600FSB at 1.35V which gives me 2.80Ghzand everything is stable.. i ran the prime95 stress test played a few games everything is normal.

the only thing is i couldnt get these 2 higher even thought i have a friend who overclocked it to 3.00Ghz and ram to 1400

If anyone has an idea of what might be wrong please help me ..

Specs:
intel core 2 duo E6550 @2.8Ghz(stock cooling)
Asus striker Extreme Motherboard
4Gb Kingston DDR2-400
nVidia GeForce 8800GTX(overclocked)
Wndows 7 Ultimate 64bit

Set your fsb to 440 or 1760 fsb and back your RAM down to 440 or 880. You don't need the RAM to go higher than 1:1 ratio as there is no gain and only increases the chance of instability from the overclock.

If it doesn't work even with increaded voltage, then it's your CPU or mobo hitting the FSB wall.

Thanx for the quick reply..

i tied what you said but it didnt work..
the bios screen comes up and freezes.
i tried seting the voltage higher to 1.45V but i got the same result..
i dont think it has hit the wall yet becouse as i said my friend overclocked it for me to 3.00 ghz.. there was a slight problem tho becouse it kept droping down to 2.8Ghz and coming back on to 3.00 when it needed to..

any ideas?

You are trying to overclock without a good idea of what you need to do.

Start over.

This should be your first stop.
HOWTO: Overclock C2Q (Quads) and C2D (Duals) - Guide v1.6.1
http://www.tomshardware.com/forum/240001-29-howto-overc...

Next stop should be a guide for your particular motherboard. Google is your friend.

Go through the guides. Then take your core voltage off Auto and set your memory voltage to factory recommended values. Change the System Memory Multiplier (or whatever your BIOS calls it) from AUTO to 2.00, 2.00B, or 2.00D - whichever you need to set the Memory Frequency to twice the FSB. Then when you increase the FSB, the memory clock will rise in in proportion with it. At an FSB frequency of 266 MHz, your memory clock should be at 533 MHz. That seems low, but don't worry. It will increase pretty quickly.

Download CPU-Z to check your FSB:RAM ratio. It should be a 1:1 ratio.

For a serious overclock, you will need better than stock cooling. Here are three under $50 heatsinks that are pretty popular:
COOLER MASTER Hyper 212 Plus

Sunbeam
http://www.newegg.com/Product/Product.aspx?Item=N82E168...
Xigmatec Dark Knight
http://www.newegg.com/Product/Product.aspx?Item=N82E168...

They all require a somewhat different approach to applying thermal compound.

And they are pretty large, so they might not fit inside your case.

Remember these are guides, not cookbooks. YMMV.

Tanx for the reply..

i will read this now. thanx:) 

i have looked around but there isnt much forums and not much of them realy help.. but tanx neway..

and yes i was gonna buy a cpu cooler but the case is too small so i will have to buy a new case first as liquid cooling is quite expencive nd we're in the recesion session:( 

thanx for the help.. realy appreciated:)
