DDR3 1600 w/ i7: Clocking issues?

[Mill]

Wait - 1.475 vCore? Isn't that really, really high?

 

[Badbonji]

Why yes, yes it is. But there will be a Vdrop, (drop not droop) from BIOS which will put it at 1.45V, which is a bit on the high end but helps to work out a good overclock before attempting to lower it.

Set vcore to what your CPU needs for your oc. The settings in the pic are a little high but they should get you a clean boot with your mem @ 16000 then you can start relaxing them.

16000? Fastest ram ever!

Any luck yet?

No luck Just won't boot when I raise the BCLK. Doesn't help that every time it fails, I need to reset the CMOS, and do ALL the settings again. The CMOS reset button (and the battery, too) is hidden under the graphics card so I have to take that out, hit the button, reseat the graphics card... such a pain

whoops.... I wish I had some ddr3-16000

From MIAHALLENress the power button rapidly 4 or 5 times...she starts right up . Okay start slow change your bclk to 137 then up by 3 till it wont boot. You have a good X58 board capable of 200+ bclk unless it defective.

Fill in this EVGA Bios Template with your current settings and post back we will get your mem sorted out.

I'll give that a shot tonight and report back here, thanks.

Just to satisfy my intellectual curiosity, and guesses as to what is causing it to fail, given that the clock speeds on both memory and cpu are LOWER when I raise the BCLK and drop the multipliers?

 

[trents]

Oops! Didn't read very carefully. You're asking about DDR3 timings, not DDR2. Can DDR3 really go with a 1T at naive speeds? Most DDR2 can't even do that.

 

[mgoode]

Yes, I can run mine @ 1t all the way up ddr3-2000
