Welcome to the forums

Just go up one notch at a time with the Vcore until stable. Unfortunately, there's no definitive answer to what is safe, anything above the stock VID has a potential for damage, but there are plenty of people running their CPUs much higher than the stock VID with no ill effects.

Just go as high as needed, but if you add more than a few notches and it's still not stable, try adding a small amount of QPI/VTT and you may find that this does the trick - It's just a bit of a balancing act and some CPUs are easier to balance than others

Awesome cheers for quick reply!

I'm a complete noob so one notch would be up to 1.21 right?

Yes, if you were at 1.2v

Ive just been on corsair website for my ram and it says to set the QPI/DRAM volt to 1.3-1.35v is this needed??

Only if it's not stable. Depends on your CPUs memory controller and how good it is. In general, I've found that my 1600MHz dominators don't need much if any extra QPI voltage unless it's accompanied by a hefty overclock on the CPU too.

Thanks again,

got my new setup at 1.3v at 3.8, running prime95 for an hour and a half, about 37 idle and 69 at load. Tried 4 but it BSOD within 10 mins, will go back and tweak when I got some more time.

All in all I'm v.happy

I would really like to start overclocking my Core i7 920 D0 with my Asus P6T Deluxe V2 motherboard.

I do have one question about the overclocking. It says to put DRAM Frequency - DDR3 - 1282MHz but I am using this corsair dominator 1600MHz ram:

CORSAIR DOMINATOR 6GB (3 x 2GB) 240-Pin DDR3 SDRAM DDR3 1600 (PC3 12800) Triple Channel Kit Desktop Memory Model TR3X6G1600C8D - Retail

Please let me know if I should put 1600MHz or the number you mentioned... and also would this in anyway make my ram less performance?

Clunk · #38 29-08-2009, 01:25

Yes, set it to what it says in the guide and you will find that as you up the BCLK, the memory speed will rise too. If you set it to 1600MHz before you start, the memory will be running faster than it should as soon as you start upping the BCLK, so you'll end up with an unstable PC pretty much right away.

After doing the cpu overclock my ram would be at 1600 mhz?

Also if anything goes wrong what should I do to get back and running again?

I am using the Asus Deluxe V2 motherboard.

With the oc i have my ram is running at 1391Mhz and the next option is 1765mhz or so and that is a big jump from one option to the other so what you can do is tighten up the timings. My ram is 8.8.8.24 but im running it @ 7.7.7.21 to make up for the loss in mhz. I haven`t tried to run my ram at 1765mhz as i think it would be unstable but i have been wrong b4 lol.
