Hi , i am OC to 3.4GHZ (378x9) atm with my Q6600 , i just finished a 10hours test and everything seems fine ...

here is my question ... Should i let my dram ( ddr2 800mhz ) voltage to auto ? or should i set it to 1.8v since it dsnt go over stock Mhz (800) atm it run at 756mhz...

i also still have my ram set to 5-5-5-15 , should i try it to 4-4-4-12 ???

thx you

You can set it to auto, but I prefer to set it manually. You also can set your timings to 4-4-4-12 if you want, but that may require more voltage.

If you do change your settings, remember to stress test the RAM using Prime95's or Orthos's blend test for at least 8hours.

Yeah, a bit faster. Maybe a few seconds faster if you do any encoding or a few frames faster if you play games.

well , i just locked my dram Voltage to 1.8 then i did set the ram clock to 4-4-4-12 and i was not able to enter windows or bios anymore ...

i had change and after some reboot , been able to go back in bios and change it back .

i guess its because the ram was seeking for more V but can i push it over 1.8 even if the ram spec is 1.8 ??? i dont want to fry it .

also if it happen again ( i mean , if i cant enter win/bios ) how can i reset bios to default ? p5k-e jumper ? remove battery ? idk

what memory have you got?
check manufacturers website for specs (max voltage)

If it's stated for 1.8V, then you should leave it there. Anymore would be considered, well, overclocking. I'd say 2V could be fine, just make sure it doesn't get too hot.

You should refer to your motherboard manual. It probably has to do with OCing RAM, like if one isn't stable you use the other setting, but I don't know for sure.

it refers to command rate CR1/CR2 a.k.a. 1T/2T.
if your ram is not high spec, i'd set it to "2n"

the same happen when i try to put the ram at 2n than when i tryed 4-4-4-12 , the system dont even boot and freeze ( freeze also in bios )

maybe the voltage is the problem , but im scared to go over 1.8v , dont wanna burn DRAM ..

and i did try to OC 3.4 to 3.6 but there is not much difference between both , so ill stay at 3.4ghz ( i guess 1mhz over stock speed is enough way enought )
