reviving and overclocking an intel c2d e7300 system crash

Ok, I'm an older newbie but i need some help.
I have this old system that I am trying to revive and use for a media center in my living room.
Everytime I go to try and tweek this thing I crash. I cannot see anything in the bios to untie the cpu speed from the ram. the ram is supposed to be 400mhz but i cannot get it to run at 400mhz with only changing that in the bios. this system crashes all the time, what can i do to help this along... oh, I have a huge heat sink and fan on this thing, thermalake 95w series, It's massive compared to stock.

the report below is all things auto.
help please.

  1. Best answer
    I had problems like this with Intel's 1066mhz cpus. The boards are origionally designed for 800mhz cpus, so the bus is "200mhz" by default, and when you put in the new cpu, it runs at "266mhz", so it tells the system to run at "266mhz". Your HT ussually gets underclocked because the ram cant handle being OC'd that far. Your 800mhz ram(ddr speed in bios gets divided by 2) would be oc'd to 1066 if it did not. That cheap brand ram most likely cant handle it which is why it crashes every time you OC.

    I would stop trying to push it and live with it, that cheap asrock board isn't for overclocking, and it isn't much of a performance difference to begin with.
  2. i have Samsung brand ram also that is supposed to be 400 mhz and it does the same thing. I bought this board because it is one of the few that you can get that is lga 775. It also IS for overclocking. I can oc it to 300mhz cpu with a 10x and run the ram at 400 (333 before overclock) and it is ok (stable) but beyond that it crashes. The mb can handle ddr3 ram, maybe that is what I need to invest in. I have read where ppls have gotten 4.0 and higher from these cpus. I want to push this one that high.
