why my pc freezes when I oc it beyond 2.8ghz?

someone says that it can oc up to 3.2ghz at stock cooling but in my case it freezes when it reaches above 2.8ghz.

I want my cpu to cope up with my gt 630 because even I lower my resolution at 800x600 and very low details it has the same fps with 1024x768 at high setings(F1 2012)

CPU: Intel Pentuim Dual Core E2180 OC'ed at 2.8 ghz
GPU: gt 630 2gb
RAM: 3GB Kingston DDR2
MOBO: ASRock 945GCM-S
PSU: POWERLOGIC ATX-500W
HDD : 500GB HITACHI 7200RPM

Your CPU's default strap is 200 FSB. That it hits 280 FSB is pretty good in and of itself for a budget board. You will need to loosen up tRD and change the strap settings in the BIOS. (if it's exposed, that is) Of course the CPU and memory themselves should be capable, too. Many E2xxx chips indeed did 3.0 GHz, but there is no guarantee when it comes to overclocking.

Here is a reading material. It's a very comprehensive article on FSB-era overclocking. It has lived out its usefulness but may be able to help you.

it has a jumper named oc800 if it is off its default is 200 fsb but if it is on the default is 266 fsb, it is set to 266 but still it does not pass beyond 280 fsb

What is your memory rated at?

OP, you're kidding, right? Be thankful for what you are getting. What someone else got for an overclock is irrelevant (especially since they probably had different hardware!)

Buy a new computer if you want something faster.

Edit: Btw, not a chance that chip will do 3.2 on a stock Intel cooler.

I had a pair of E2140 CPUs, overclocked to 3.2Ghz (400FSB), and I had to use an aftermarket cooler.

...but it's only a 40% overclock!!111

maybe your CPU hit its limit for the voltage you are using,

and 945GC, this chipset only supports FSB up to 266, after that it can't keep the PCIE clock locked, and you need to be more careful, also keep an eye on the memory clock, it may be the cause of your "problem".

My guess would be voltage limit or even possible fsb wall on your chip

I wouldn't trust that much of an oc in the first place, some errors are hard to detect even after hours of stress testing with Prime95/linpack/Memtest86+/HCI Memtest, etc. Be sure to run those tests anyway though, if you are LOCKING UP at 2.8 that probably means you are accumulating errors at lower speeds.

Looking at a picture of that board the power delivery looks very basic (only 3 phases)
Chances are that motherboard isn't up to the task imo
