Oc kingston pc2 6400 cl6 800 mhz ram

i tried to boost my ram up from 800 mhz to 1066 mhz but i found over heating with my system and cpu

my specs.
mobo gigabyte ep45-ud3r rev(1.1)
xfx 9600 gso
2x2 gb kingston pc2-6400 cl6 240 , 800 mhz
i tb wd sata 2
h.e.c 500w psu

i changed some options from the bios which are :

performance enhance (standard)
mch freq latch 333 mhz
system memory multiplayer spd 4.00b
dram timing spd auto

and i found
V DRAM 1.98V

i didnt play with the voltage and left all other options and timings auto

would any one give me some steps or tell me whats happening ???

  1. How do you know any of your parts are overheating? What are you using to determine this?

    if your DRAM timing is set to auto, the bios may not report accurately and will just show whatever the last manual settings were. Use CPU-z id or such to check the actual speed of the ram and its timings.

    Make sure the command rate is set to 2t if you want it to overclock to 1066mhz, its a sizeable jump.
  2. Oh, forgot to mention that you will want to check into the SPD timings. When I have attempted similar things in the past, I used other brands of 1066mhz ram as a guide to what the "standard issue" timings of a DDR21066mhz chip would be.
  3. now i changed the bios settings to 266 and system multiplayer 4.00b

    while my quad q6600 is running 266x9 (stock)

    but it still show that the dram voltage = 1.98v

    i didnt change any timing or voltage (all set to auto) cause i dont have experince with that

    so i just wanna know am i ok now or that change would damage my ram ???

  4. looks good. Were you previously overclocking the CPU?

    Also, the difference in RAM speed probably won't be noticeable. You will see more gains by OCing the cpu. I have the same one and clock the CPU to 3.0ghz.
