Well the Theory is the same for AMD Over Clocking too... Stay under Limit of Temparature of 60c on load... !!!
Disable th FAN Control for the Processor...
Increase the FSB/BUS or Multiple... !!! I prefer FSB that allows step by step increase...
the CPU speed is FSB x Multiple... !!!
so increase one of them will mean u increase the processor Speed

I've overclocked my Pentium D CPU 925 3 Ghz To 3.4 Ghz by increasing the
Fsb 800 Mhz to 907 Mhz in bios.
Also overclocked my kingston value Ram 667 MHz to 680 Mhz
My Processor's idle Temp is 39C - 22 Minutes of Orthos test put the processor's temp to 44C
Are they Safe.
Ran PcMark05 & Everest Benchmarks. They all passed.
Haven't Played with voltage
Mobo is 650i ultra.

thought that it doesnt make any sense starting a new thread for this topic hence posting my query here:
I'am planning to get liquid cooling for my PC since the stock cooling from the Zebronics fans is not enough.
I have shortlisted the Cooler Master Aquagate Mini R80 Water Cooler as it is within my budget and easy to install..
wat I would like to know however is that if its worth the price or not?Further is it easy to maintain and if Rs 3030 is the right price for it from IT Depot?
Lastly if I choose to OC my rig will this cooler be sufficient?

Why water coolers ?? go for ThermalRight ultra Extreme 
This is for entrana and all users of C2D with 6X50 series processors.@entrana please update your bios to the latest official(not beta) at XFX's(www.xfxforce.com) site you'll have to register there.Please reset the bios config to default before flashing.
Ok the Temperature at full load(i really mean full load) for these processors is 72C and not 62C.Also the tjunction
for these processors,i.e. the temperature at which the cores shut down is 100C compared to older C2D processors
which is 85C.
Please download Orthos,Core temp,CPU-Z all free software.I think choto has given the link to all these software
downloads in the first page.
Please read carefully and do not skip.
I have overclocked my processor to 2.8Ghz.Currently i am testings with orthos.My ram was Kingston 667Mhz which i
overclocked to 800Mhz.

When overclocking you need to bear these things in mind.
1. Vcore(voltage to CPU core)
2. Memory Voltage
3. Real Bus Speed,theoretical Bus speed and theoretical processor speed
Your mobo should be good,i mean it shouldn't deviate from the Vcore you set by you by too much.For starting i would like to
suggest you that you set your Vcore to 1.23V-1.25V.This would help you lower your temps.Also after doing this stress
test CPU with orthos and see the maximum temps.If the maximum temps are 60C-63C then your safe.
Now since entrana has 800Mhz ram u'll have unlink the processor and ram speed so that only the processor is
overclocked.Look in your motherboard manual for details or google more for help since i don't have this mobo.When
you unlink the ram the ram modules run at their full speed until the prcoessors bus speed closes to the rams speed.
Now some numbers.
Your processors bus speed is 333Mhz and mutiplier is 8.Now 333Mhz*8 gives 2.66Ghz.Also 333Mhz*4 gives theoretical
bus speed 1333Mhz.Most people are only able to utilize actual bus speed in dual channel configuration.
Also theoretical bus speed/2 gives Memory Speed 1333/2=667Mhz,1600/2=800Mhz when the ram speed and processor speed are in sync.
U'll have to see what your motherboard's bios provides u to overclock.Actual bus speed or the theoretical bus
speed.The multiplier on C2D processor is locked so you cannot overclock by increasing the mutiplier which would have
been safer.
Now increase the bus speed calculating the theoretical processor speed(333-3XX(or something)*8 ).
Save the bios config and exit.If the pc does not boot then reset the bios and boot again and lower your speed in
Mhz.
Everything is similar to what choto said except the temps at TDP and tjunction.

^^I know that P5N-E SLI does not have active cooling for NB and no cooling at all for SB but the reviews on most sites say that this board easily overclockes to 500Mhz just like the P5N32-E SLI.
BTW i am desperately trying to grab two pieces of cooler master CoolViva Z1 coolerfor my 8600GT SLI.I don't want to buy online.Prime ABGB and itwares do not deal in VGA coolers for cooler master please advise.Currently i am in discussing with matrix ltd.

I am using Q6600 on stock cooling. I tried overclocking it to 2.8GHz with vcore voltage set to 1.264 volts.
The no-load temps are ~32-34 for all four cores. when I use super-pi to stress the CPU then even at 100% load for all the cores the temperature does not go above 52C. But when I use Orthos for stability testing the temperature of cores become 65C, 62C, 63C, 65C.
Is there anything I can do to clock my cpu to 3.0GHz (except than buying a new cooler).
Also will decreasing the timing of RAM give a boost to my PC. I am using transcend 800MHz RAM.

See clocking to 500FSB is not the point here, i am aware what the NV 6 series chipsets are capable of. Point is they get extremely hot and it is scary,trust me.Also with increasing heat, stability decreases. 680i heats a lot and if not given proper cooling, many have managed to kill the chipset while clocking due to excessive heat.
So just put a 120mm high cfm fan over the NB heatsink and a 80mm over the SB, that should keep things cool.
If possible try applying AS5 on NB heatsink, shud help reduce temps.
SuperPi does not completely stress the CPU as Orthos does. Orthos is the ultimate stress testing test,hence you see the temps rise.I am using Q6600 on stock cooling. I tried overclocking it to 2.8GHz with vcore voltage set to 1.264 volts.

The temps you have posted are very low, reason being G0 stepping of your Quad.
Clocking it to 3G is no big deal, keeping things cool with stock cooler is just expecting too much from the stock cooler.
Tight timings always translate into performance. The core architecture is not Bandwidth hungry. But tight timings even at low speeds is always welcome.
For example, 800 @ 3-3-3-8 is much faster compared to 1000 @ 5-5-5-15
Remember, tightening timings depends on the chips on the ram involved.tightening timings will also require some vdimm bump.Generally Micron chips do tight timings.Promos also does upto come level, Samsung, Hynix, Elpida cant do tight timings. So if a particular RAM doesnt do tight timings, it might do high speeds at loose timings.
Hope this helps.

In the zone
i am looking for a cheap overclocking mobo.....in intel side,good mobos are expensive..so suggest a good cheap overclcoking mobo in AMD side.....
also see this : Biostar GF7050V-M7 NVIDIA GeForce 7050 1333 FSB Rs.3350
considering its biostar and 1333 mhz will it overlcock well ? its for intel....no proper review for this is found in net....also will it support the upcoming penryn proccies ?

@darklord - Thanks for your suggestion.
I am not newbie in overclock zone (theoritical overclock)
but practically this my 1st OC. My previous Mercury 845 mobo didn't
have any option to overclock. I've read many articles before overclocking
my rig to be on safe side.
But I'am a little panic about increasing voltages. So I don't even touch
voltage settings. I always want to take out max performance with stock
cooling ie stock HSF & stock voltages
Note:Mine processors cpu multiplier is locked. So I was unable to change it
in Advanced Chipset Features > System Clocks
Here are my OC procedure's:
1.Flashed bios with latest version. Go to Bios > Advanced Chipset Features >
System Clocks - Disabled all kinds of spread spectrum settings. Didn't change
the pcie frequency though. But gamers should seriously consider to rise it atleast
10-25%. Didn't change HT multiplier settings.
2. In FSB & Memory Config > changed the FSB and Memory Clock Mode to unlinked.
Bumped the "CPU FSB (QDR), MHz to 940 MHz & MEM (DDR), MHz to 685 MHz.
3. Got into Memory Timing Settings and changed them to Following
Memory Timing Setting - Expert
x tCL (CAS Latency) - 5
x tRDC - 5
x tRP - 5
x tRAS - 15
x Command Per Clock (CDM) - Auto (1T)
** Advanced Memory Settings
x tRRD - Auto (3)
x tRC - 18
x tWR - 4
x tWTR - Auto (9)
x tREF - Auto -7.8uS
4. Got into Advanced Chipset Features > CPU Configuration
Limit CPUID MaxVal [Disabled]
x Intel SpeedStep Disabled
CPU Thermal Control [Disabled]
C1E Enhanced Halt State [Disabled]
Execute Disable Bit [Enabled]
5. Got into System Monitor Option & Dynamic Fan Control
My mobos Bios Automatically Clocked all fan speeds @ 100%
6. Disabled all unused sata, ide & fdd ports from Integrated Peripherals Menu
to save power.

@choto bhaiya
is it possible to overclock laptops n wont it cause some problem..
my acer 4710 (havin T5300 1.73 Ghz procy @533Mhz FSB) was overclocked by the the acer company itself. CPU-Z shows FSB speed of 800mhz. n i dont hav any heatin issue ie ideal temp is 43-48 c max temp is 53-54 n in 100% procy use (means during any benchmark test) it reaches 60c....
but i want know can i change OC settings coz in my bios their no options to customize anythin.
