Get the twin pack thing of LL sticks from corsair, they just rock beyond all other RAM chips, i have a Nforce board, only one stick of ram but still its still good, get 2x256 so you can take advantage of the dual channel, it should have little or no effect on how high you can overclock your ram, thats a problem with stupid VIA, not nForce. Umm lets see do i have any other advise...
I am also relivily new to OCing but i know a little
so about your questions
about your question about upping to vcore voltage (cpu voltage) you dont need to unless...go download a thing called Prime95 if you havnt already, its a great tool for testing stability of your overclock, for ram and cpu, so if you can run the torcher test on that for 24-48 hours you can consider yourself pretty dang stable, now if any of that reports erros up your voltage, untill your not comfortable with your temps anymore, then maybe try decresing your overclock, somtimes a few Mhz is all it takes.
RAM, go corsair, crucial is great stuff, but not for overclocking, i have had both now so i know
the 3200 sticks are great, and to anwser your version question buy the sticks from newegg, for two reasons 1. newegg rocks, 2. they sell the 3200 version 1.1 chips, they are what is working with the nforce boards better than the 1.0 chips so buy from them, or i guess googlegear sells 1.1 too if you want to go that way.
ALL THOSE SETTINGS IN YOUR BIOS...
its great isnt it, i got my asus and loved all the new setting sin there, but even it could still use more, the ones you want to pay attention to are the
FSB, Mulitpier, FSB/RAM ratio (its in percents on my board, i dont know about yours) but its what tells how fast the ram should go compared to the FSB, choose either sync or 100% this will run your ram the same speed as everything else (but it will be double (DDR)), All your voltages.
first unlock your chip, or maybe it will unlock itself since its a t-bred-b so once thats done lower your multiplier and relax your memory timings either choose optimal or make the numbers HIGHER. Raise all your voltages to the highest point you feel comfortable with, Then crank up the FSB to 166, then 180, then 190, 200, etc, find where it wont boot anymore, reset your bios (that jumper thing) and find the number inbetween that your ocmputer will boot on, then redice that a little, just to make sure theres no problems later.
Crank up your multiplyer, until it doenst boot, turn it back to the one it booted on and reset the FSB, now tighten (lower) your timings to as low as they will go, different systems react differently to different timings so you will have to experiment, like mine will actually for some reason get better numbers at 2-2-2-6 than 2-2-2-5, i dont know so yeah. If your air cooling, try to keep the voltages within reason, dont go more than 1.85 on your CPU (if you have good air colling) and dont go more than 2.8 on your memory unless you want to void corsairs warrenty.
You can see what i run for air cooling below, and i have 1.8 on my cpu and 1.6 on my memory, but thats becasue i dont have a tbred, you lucky!! and my FSB wont go any higher so theres not much point in raising anything anymore till i can fiz that.
But thats about all i can think of, i hope i helped a little, happy OCing!!
