I am about to get an xfx gts 250 1 gb. My cpu will surely bottleneck(core 2 duo 1.8 Ghz)(e4300). By how can I overclock it with a stock cooler on an intel d945gccr motherboard?

Check to see if you can change FSB in BIOS on the Intel mobo. You wont't be able to change vcore tho. With stock vcore an E4300 usually tops out @ ~2.6Ghz (290x9).

My motherboard is intel. Not xfx, asus etc. Will I be able to overclock the cpu?

As said, you'll have to go into your BIOS and find out what options are available then report back.

There's a few pin mod for the E4300 to have a FSB of 266mhz or 333mhz and a vmod to increase the cpu voltage.

That'll take you to 266*9= 2.4Ghz or 333*9= 3.0Ghz... but with stock cooler I'd get the 266 FSB pin mod just to be safe. I have a E4300 OC to 3.0 Ghz but with AC pro 7 + AS5.

edit: with the pin mod you don't need to change anything in the MB bios.

Do you have the details of the pin mod for both 333FSB and the various VID values?

Back then I was only able to find 200->266FSB mod for E4x00 documented here.

I will be getting a 550 watt powersupply.
One more thing... Is it safe to overclock?
What problems could I face?
How much will a good cpu fan cost?

I have this cooler and my E4300 OC to 3.0Ghz with no problem.

You'll need a case with good air flow.
Make sure the temps don't go too high.
Overclocking is safe as long as you're carefull not pushing the CPU too high over its limits. What's dangerous with overclocking is if you give too much volt to your CPU.

The PSU must be a very good brand with stable 12v rails.

Hi
I thought that buying a new cpu will be more subtle... I am looking at Q9550(quad core 2.8 GHz). Only thing is that I don't know if my zebronics realwatts 500W pro series can take it. Right now with the XFX gts 250 core 1 gb and e4300 things r goin smoothly.

here is the info on the psu, graphic card and cpu..

input
Item name- Zebronics realwatts pro-500
Voltage- 115/230Vac
Frequncy- 50/60Hz
Input current- 10A/5A

output
22A(+3.3V) and 15A(+5V) combined gives 130W
19A(+12V1) and 19A(+12V2) combined gives 384W
0.3A(-12V) gives 3.6W
2A(+5Vsb) gives 10W
Total max output 500W

All have reg +/-5% except 3.6W which have +/-10%

Min power for my graphic card XFX gts 250 is 450W
power required for the processor I have now(e4300@1.8GHz) is 65W
power required for q9550@2.8GHz is 95W

Till now most of friends tell it will be fine.
What r ur opinion?
