Hi there, im having alot of trouble with my new setup (system info in sig) and after some help, ive tried alot of forums but still have not found a solution after several days now of trial and error after error 
The problem is i have 4x512mb OCZ PC3200 ram in my DFI Sli infinity mobo. The memory was originally running at 200mhz. Started up a game and the system lockup after about 10mins of play and i had to hard reset. I then tried @ 166mhz and then games pretty much instantly locked up. only 133mhz will work for hours on end no problems. When i have just 2x 512mb sticks of ram in the mobo running @ 200mhz there are no probs either, and it could be any combination of the 4 sticks.
I have tried alot of different timings and settings in bios with no success, only 133mhz is stable yet after abit of research i should have no problems at all running the ram @ 166mhz and of course cpc is set to 2T.
After more forum posting and research i find this could be a memory controller problem and this is where my main question comes into play. Can you solve a memory controller issue so i can run the 4x512mb ram @ 166mhz (or better if possible). Is it possible that i just need to update the bios or does it come down to hardware and basically there is nothing i can do but replace something?
If any more detailed info is needed on anything let me know and ill post back.
Thank you for any help out there!
