Best DRAM speed for i7-920 @ 3.33 ghz??

[the_wildcard]

I intend on leaving my computer overclocked to 3.33 ghz. I've got a baseclock set at 166 and the dram frequency at 1333. Everything else is set at Auto in my ASUS p6x58d bios.

My ram is DDR3 6 GB (3 x 2 gb) Corsair Dominator TR33X6G1600C8D which is rated at 1600 mhz at 8-8-8-24. Current speed is 1333 mhz.

The current timings at 663 mhz is 8-9-9-24.

My questions are:

1) What is the optimum DRAM speed (1333, 1600, etc) should I be running this ram at, if I want to maintain the 3.33 ghz CPU speed?

2) Can I set the Asus Bios Ai Overclock Tuner setting to XMP, then set the baseclock frequency to 166, then set the dram frequency to 1666?

3) Should I manually enter in the timings?

If the XMP settings are working I wouldn't change them. You can manually set the the frequency using the divider.

If your using the automatic overclock feature in the bios I would read up and manually overclock as the auto generally gives more voltage than is necessary.

Are you using the stock cooler?

Cory, thanks for the reply. To answer your question, no, I am using a megalahem. Probably overkill for just 3.33 ghz, haha.

I'll take a look at the thread and test out your advice. I agree that I do not want to use too much of the automatic, especially when it comes to the voltages. I'd rather read up and set/lock those manually.

Thanks.
