ok so i got this ram http://www.overclockers.co.uk/showproduct.php?prodid=MY-039-KS
its meant to be able to run at 1066mhz,but when i built the pc it was set to 800mhz. Im using a gigabyte GA-EP43-DS3 motherboard and an e5200 cpu. So far ive overclocked the cpu to 3.33ghz,so now the ram is also set to 1066mhz...the problem is my pc keeps crashing when im in game e.g "gearsofwar has stopped working"

The cpu fsb is at 266mhz,cpu voltage is at 1.36v and the ram voltage is at 2.2v.
the ram timings are at 5-5-5-15
could somebody please tell me why i keep crashing?all the temps seem fine,like the cpu would be at 45 degrees in game. At stock bios settings the pc runs perfect

Thanks

It's not always possible to run the 1066 memory at it's stock speed with the E5200/P43 combination. The closest i've got is ~933MHz clocked at 3.5GHz using the x12 multiplier (see sig)

You could try slackening timings and upping the NB a little and other subtle tweaks but i suspect you may have to resign yourself to running your memory slightly under stock via the memory divider - it's not unusual and in some cases to be expected so don't feel too bad if this proves to be the case.

I'll dig out a couple of threads for you as an example/explanation...

but the thing is im running 1066mhz now,seems to run fine outside game but as soon as i go into game and play for a few minutes it seems to crash....grrr

Here you go - you may find both these threads of use:

Link 1

Link 2

In Link 1 you could try my settings and see if they work for you (although you will probably find you need to use a higher vCore voltage) - as a 3.5GHz overclock with memory at ~933MHz is faster than a 3.33GHz OC with memory at 1066MHz.

In Link 2 you will see that Big.Wayne has reached 1066MHz on a P45 MB using the e5200 but most of the P43 owners have had to take a small MHz hit on the memory to achieve our high clocks

If you have to drop a couple of hundred of MHz for stability you won't notice any discernible speed difference in everyday usage. I too could get it to boot set at 1066MHz but i could not get it prime stable and always had cold boot issues. Stability and peace of mind won over a miserly 133MHz.

I only bought 8500 memory for the greater clocking flexibility - i didn't buy it with the expectation of hitting 1066MHz plus a respectable CPU clock.

I would get the machine stable, for now, with a memory setting that is stable for the clock you want to achieve and then, over time, try out differing combinations of settings and you may eventually hit the magic combination.

Good luck.
